Extracapsular Proximal Femoral Fracture Intramedullary Nailing Failed Fixation

Authors

Paul L Rodham,Vasileios Giannoudis,Peter V Giannoudis

Published Date

2024/1/31

Fixation failure in the proximal femur is an uncommon phenomenon, occurring most commonly as a result of biomechanical failure. This may be due to failure to achieve reduction or utilisation of an incorrect entry point, both of which can result in a varus deformity. Where this occurs, the proximal femur must be valgised and rigidly secured. If there is a residual bone defect it will require management with either autograft, allograft or a bone substitute.

PurposeThe number of total knee replacements (TKRs) performed per year has been increasing annually and it is estimated that by 2030 demand would reach 3.48 million procedures per year in the United States Of America. The prevalence of periprosthetic fractures (PPFs) around TKRs has followed this trend with incidences ranging from 0.3% to 3.5%. Distal femoral PPFs are associated with significant morbidity and mortality. When there is sufficient bone stock in the distal femur and a fracture pattern conducive to fixation, locking compression plating (LCP) and retrograde intramedullary nailing (RIMN) are commonly used fixation strategies. Conversely, in situations with loosening and deficient bone stock, a salvage procedure such as a distal femoral replacement is recognized as an alternative. This meta-analysis investigates the rates of non-union, re-operation, infection, and mortality for LCPs and RIMNs when performed for distal femoral PPFs fractures around TKRs.

Distal Humerus Failed Plate Fracture Fixation

Authors

Chang-Wug Oh,Peter V Giannoudis

Published Date

2024/1/31

Distal humerus fractures present with either intra-articular involvement or they are pure extra-articular fractures. Initial clinical evaluation must assess the neurovascular status of the affected extremity and associated injuries to the ipsilateral shoulder and wrist joints. A computed tomography (CT) scan must be obtained when extension of the fracture is suspected in the articular surface or when there is intra-articular involvement with comminution. Bic-column fixation usually provides optimum stability allowing early range of motion of the elbow joint reducing the risk of joint stiffness. We present a case that failed following fixation, analyse the aetiology of failure and discuss the treatment that was successfully implemented.

Failed Fixation of Capitellum Fractures

Authors

Paul L Rodham,Vasileios Giannoudis,Peter V Giannoudis

Published Date

2024/1/31

Failure of capitellum fixation is rare. The capitellum when fixed is susceptible to significant shear forces due to its anterior centre of rotation, particularly when loading the elbow in extension. Fixation should aim to best resist these forces, commonly attained through headless compression screws orthogonal to the fracture plane. Rehabilitation should be guarded, and whilst range of movement should be instigated early to regain range of motion, load bearing should be gradually reintroduced. Revision fixation should concentrate on achieving an anatomic reduction, and compression orthogonal to the fracture plane.

Failure of operative treatment of fifth metatarsal fractures may have a variety of aetiologies. The most common are technical errors, for example, inappropriate fixation methods, i.e. small screws that break, leading to non-union. However, overlooking the presence of a simultaneous cavovarus foot deformity and failure to address it during the index procedure may lead to overloading of the lateral column, thus predisposing to failure and/or non-union.

Intertrochanteric fractures are a common type of proximal femoral fracture, and account for high morbidity and mortality. Early recognition and management of such fractures is important, with surgery preferably undertaken within 48 hours. The choice of surgical strategy remains variable between centres and individual surgeons; in part because evidence to support a specific strategy has been weak. Herein, we provide the latest evidence on the management of these fractures.

Metal work failure after fracture fixation is not common. However, when established it may be associated with pain, limb deformity, functional impairment and need for revision surgery. While the causes can be multifactorial including non-compliance, poor bone stock, non-optimum fixation, selection of wrong implant, metal fatigue and infection, its true incidence remains unknown. Herein, we report the incidence of metal work failure after fracture fixation in different anatomical areas.

Published Date

2024/1/31

Failure of operative treatment of subtrochanteric femoral fractures may have various aetiologies. Subtrochanteric femur fractures are difficult to treat due to strong deforming forces at the fracture site, tenuous blood supply, and the immense load-bearing forces exerted through the peri-trochanteric region. Adequate reduction and stable fixation are paramount when treating these fractures to optimize patient outcomes. Special attention should be made to avoid poorly reduced fracture (varus malignment) and lack of medial cortical support.

The treatment of painful KOA in adult patients with ITP has not been well studied yet. We conducted a prospective, double-blind, randomized, placebo-controlled trial to evaluate the efficacy of intra-articular allogeneic PRP injections on symptoms and joint structure in patients with KOA and ITP. 80 participants were randomly allocated in a 1:1 ratio to allogeneic PRP group or saline group. The primary outcome was the WOMAC total score at 12 months post-injection. The number of patients in each group who achieved MCID of primary outcome showed a statistically significant difference only at 3-month (27/39 vs 5/39, P = .001) and 6-month (15/39 vs 3/38, P = .032). The difference in WOMAC total score exceeded the MCID only at 3-month (mean difference of -15.1 [95% CI -20.7 to -9.5], P < .001). Results suggest that allogeneic PRP was superior to placebo only with respect to symptoms at 3-month of follow-up.

Failure of Plate Fixation of Humeral Shaft Fractures

Authors

Emmanuele Santolini,Peter V Giannoudis

Published Date

2024/1/31

Failure of plate osteosynthesis of humeral shaft fractures could be due to several factors. Lack of adequate mechanical stability is one of them as the humeral shaft is an anatomical area subjected to great displacing forces, particularly torsion, which must be effectively counteracted by a stable fixation until fracture union occurs. Herein, we report on a fixation failure of a humeral shaft fracture stabilized with plating and discuss the etiology of failure and subsequent treatment implemented.

Distal Tibial Extra-Articular Intramedullary Nail Failed Fixation

Authors

Michael J Price,Peter V Giannoudis

Published Date

2024/1/31

Distal tibial extra-articular fractures may present difficulties to be reduced and to be stabilised with a load sharing device—intramedullary (IM) nailing. The surrounding soft tissue envelope of the distal tibia, particularly anteriomedially, is associated with a compromised blood supply to the bone and increased risk of wound-related problems that can lead to wound breakdown and development of secondary infection. Good reduction and optimum fixation are paramount to optimise patient outcomes. Failure of surgical treatment of extra-articular distal tibia fractures may have various aetiologies related to poor reduction, malalignment, mechanical instability and poor bone quality. Herein, a case of failure is presented discussing the aetiology of failure and the subsequent successful treatment plan implemented.

Distal Radius K-Wiring Failed Fracture Fixation

Authors

Michael G Kontakis,Peter V Giannoudis

Published Date

2024/1/31

The fixation of distal radius fractures with closed manipulation and percutaneous pinning is a common practice that has better results than treatment with a cast alone. Infection of the pin entry point site and loss of reduction due to insufficient stability of the construct are examples of complications of this technique. Unstable distal radius fractures, or fractures in osteoporotic patients, are better treated with distal locking volar plates. This chapter illustrates a failed distal radius fracture fixation due to pin entry site infection and loss of reduction.

Complications following fixation of intracapsular neck of femur fractures remain common; however, the provision of an appropriate mechanical environment can be employed to try and prevent them. We present a case of fixation failure due to the use of a technique that does not adequately resist the shear forces that occur during weight-bearing, resulting in shortening and varus collapse. Maintenance of length within the neck could be achieved through the use of fully threaded screws or a fixed angle device, whilst increased resistance against the shear stress experienced in this region may be achieved through the use of an orthogonal Pauwel screw.

Failure of operative treatment of acetabular posterior wall fractures may have a variety of aetiologies, with the most common being technical errors. Examples include intra-articular lag screw penetration, not recognizing fracture patterns that require either a spring or rim plate and inadequate use of bone graft for structural support in cases with an associated marginal impaction injury. This chapter illustrates an example of fixation failure of a posterior wall acetabular fracture secondary to buttress plate misplacement.

The mechanisms underlying AFF remain unclear, with hypotheses including bone turnover suppression and morphological variation. Recent studies have suggested a potential genetic susceptibility to AFF. A scoping review was conducted using PubMed to identify studies published since 2016. Twenty-one studies were identified, focusing on histological and genetic analysis of AFF patients and BP users. Biopsies and imaging modalities were used to assess histological and morphometric parameters, while genetic sequencing was performed to identify variants in target genes.Genetic studies identified variants in geranylgeranyl diphosphate synthase 1 (GGPS1) and CYP1A1 genes, which play roles in osteoclast function and drug metabolism, respectively. Functional analysis revealed reduced enzymatic activity in mutant variants of these genes, which could be further inhibited by BP use. Other genes, such as …

Ankle fractures are intraarticular and therefore require anatomic reduction to obtain satisfactory results. Even slight malreduction can lead to late instability, pain and arthrosis. Ankle syndesmosis complex consists of a significant component of the ankle joint biomechanics and should therefore accurately addressed. However, the amount of diastasis that can be tolerated is not universally accepted. Studies have shown as little as 1 mm of talar displacement can increase joint contact loads by as much as 42%. This chapter illustrates the sequence of a failed ankle fixation and its management.

Failure of midshaft femoral fractures may have various aetiologies. Midshaft femur fractures can be challenging to treat if the surgeon cannot fully appreciate the implant used, patient factors and the plan they are aiming to achieve with the implant (absolute vs relative stabilisation). Adequate reduction and stable fixation are paramount when treating these fractures to optimize patient outcomes. Special attention should be made to the use of NCB plating systems and the appropriate fracture pattern should be selected for their use.

Olecranon fractures represent 10% of upper limb injuries. Transverse simple fractures of the olecranon can be treated with tension band wiring, representing a simple and effective technique for transforming the triceps distraction forces into forces that cause fracture compression. This valuable surgical fixation technique has basic rules that only succeed if followed. Post-fixation failure of olecranon fractures is not uncommon and can lead to morbidity and increased cost of care. Herein, we present a case of olecranon fixation failure and discuss the aetiology of failure and the strategy for revision surgery.

Recent data from the UK's National Hip Fracture Database (NHFD) demonstrate an upward trajectory in the incidence of hip fractures, a trend which is expected to persist. In 2023 alone, the NHFD reported 72,160 cases, underscoring the prevalence of these injuries. These fractures are associated with significant morbidity, mortality, and economic costs. National guidelines for the surgical management of these fractures are established, although the implementation of total hip arthroplasty (THA) as a primary treatment modality varies. This review offers a narrative synthesis of contemporary literature on hip fractures, focusing on epidemiology, classification systems, and treatment options, with a particular emphasis on the outcomes of THA.

Bone void-filling cements are one of the preferred materials for managing irregular bone voids, particularly in the geriatric population who undergo many orthopedic surgeries. However, bone marrow mesenchymal stem/stromal cells (BM-MSCs) of older-age donors often exhibit reduced osteogenic capacity. Hence, it is crucial to evaluate candidate bone substitute materials with BM-MSCs from the geriatric population to determine the true osteogenic potential, thus simulating the clinical situation. With this concept, we investigated the osteogenic potential of shell nacre cement (SNC), a bone void-filling cement based on shell nacre powder and ladder-structured siloxane methacrylate, using older donor BM-MSCs (age > 55 years) and young donor BM-MSCs (age < 30 years). Direct and indirect cytotoxicity studies conducted with human BM-MSCs confirmed the non-cytotoxic nature of SNC. The standard colony-forming unit-fibroblast (CFU-F) assay and population doubling (PD) time assays revealed a significant reduction in the proliferation potential (p < 0.0001, p < 0.05) in older donor BM-MSCs compared to young donor BM-MSCs. Correspondingly, older donor BM-MSCs contained higher proportions of senescent, β-galactosidase (SA-β gal)-positive cells (nearly 2-fold, p < 0.001). In contrast, the proliferation capacity of older donor BM-MSCs, measured as the area density of CellTrackerTM green positive cells, was similar to that of young donor BM-MSCs following a 7-day culture on SNC. Furthermore, after 14 days of osteoinduction on SNC, scanning electron microscopy with energy-dispersive spectroscopy (SEM-EDS) showed that the amount …

Tibial Plateau Plating Failed Fixation

Posterior shearing tibial plateau injuries represent unique fractures requiring meticulous evaluation and planning. Initial assessment must exclude neurovascular deficit followed by temporary stabilisation with an external fixator as indicated for resuscitation of the surrounding soft tissues and acquisition of computed tomography scan for a detailed evaluation of the fracture pattern and appropriate preoperative planning. Optimum fixation would support the early range of motion of the knee joint for preservation of cartilage and reducing the risk of joint stiffness. Herein we present a case that failed following reconstruction and discuss the aetiology of failure and the subsequent treatment that was performed successfully.

IntroductionInfected tibial non-unions with associated bone loss can be challenging to manage. At present, the two main methods utilized in the management of these fractures include the Ilizarov technique of Distraction Osteogenesis (DO) using external fixator devices, or alternatively, the Induced Membrane Technique (IMT), devised by Masquelet. As there is a paucity of data directly comparing the outcomes of these techniques, there is no universal agreement on which strategy a surgeon should choose to use.AimsThis systematic review and meta-analysis aimed to summarize the outcomes of both DO and IMT, in terms of primary outcomes (bone union and infection elimination), and secondary outcomes (complication rates and functional outcomes).MethodsA PRISMA strategy was used.

Meta-analyses constitute fundamental tools of the Evidence-Based Medicine (EBM) aiming at synthesizing outcome data from individual trials in order to produce pooled effect estimates for various outcomes of interest. Combining summary data from several studies increases the sample size, improves the statistical power of the findings as well as the precision of the obtained effect estimates. For all these reasons, meta-analyses are thought of providing the best evidence to support clinical practice guidelines. However, the strength of the provided evidence is closely dependent on the quality of included studies as well as the rigour of the meta-analytic process. In addition, over the course of the evolution of the current meta-analytic methodology, some concerns have been expressed on the ultimate usefulness of such a complex and time consuming procedure on establishing timely, valid evidence on various …

In an ideal world, different options of care are discussed with patients and their relatives, resulting in a consented treatment plan. We all know this ideal case scenario is far away from reality-without going any further into issues like time constraints, work overload, shortage of staff, documentation needs etc.[2].

Bone damage arising from fractures or trauma frequently results in infection, impeding the healing process and leading to complications. To overcome this challenge, we engineered highly porous chitosan scaffolds (S1, S2, and S3) by incorporating 30 (wt)% iron-doped dicalcium phosphate dihydrate (Fe-DCPD) minerals and different concentrations of cerium oxide nanoparticles (CeO2) (10 (wt)%, 20 (wt)%, and 30 (wt)%) using the lyophilisation technique. The scaffolds were specifically designed for the controlled release of antibacterial agents and were systematically characterised by utilising Raman spectroscopy, X-ray diffraction, scanning electron microscopy, and energy-dispersive X-ray spectroscopy methodologies. Alterations in the physicochemical properties, encompassing pore size, swelling behaviour, degradation kinetics, and antibacterial characteristics, were observed with the escalating CeO2 concentrations. Scaffold cytotoxicity and its impact on human bone marrow mesenchymal stem cell (BM-MSCs) proliferation were assessed employing the 2,3-bis-(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide (XTT) assay. The synthesised scaffolds represent a promising approach for addressing complications associated with bone damage by fostering tissue regeneration and mitigating infection risks. All scaffold variants exhibited inhibitory effects on bacterial growth against Staphylococcus aureus and Escherichia coli strains. The scaffolds manifested negligible cytotoxic effects while enhancing antibacterial properties, indicating their potential for reducing infection risks in the context of bone injuries.

IntroductionCarbon fibre-reinforced polyetheretherketone (CFR-PEEK) plates represent an exciting development within trauma and orthopaedic surgery, offering advantages including radiolucency, material properties similar to bone, and lack of localised tissue reaction. As more call for trials examining their use, there is no data available as to the acceptability of these implants to patients. This study aimed to therefore examine the acceptability of CFR-PEEK plates to patients undergoing fracture surgery.MethodsThis was a prospective cross-sectional survey of patients undergoing surgery for a fracture of the ankle, distal femur, distal radius, or proximal humerus. Once a decision had been made to pursue operative fixation with a plate, patients were provided with descriptions of both CFR-PEEK and stainless steel and titanium metal implants alongside the current clinical evidence. All patients undertook a …

Background The incidence of hip fractures and subtrochanteric fractures in particular is increasing, along with the globally expanding aging population. Intramedullary nailing remains the ‘gold standard’ of their treatment. Blood loss can be a result of the original trauma, but also secondary to the subsequent surgical insult, especially during the reaming of the intramedullary canal. Objectives The aim of our study was to report on the blood loss and incidence of blood transfusion in patients presenting with a subtrochanteric fracture treated with intramedullary nailing. Most importantly, we aim to identify factors associated with the need for transfusion within the first 48 h post‐operatively. Methods Following institutional board approval, 431 consecutive patients (131 males; age: 79.03 years old, SD 13.68 years) presenting in a Level 1 Trauma Centre with a subtrochanteric fracture treated with an intramedullary nail …

We report on the treatment of a neglected displaced vertical shear pelvic fracture with functional impairment 6 months after injury in a 74-year-old woman with underlying osteoporosis. She was managed with open reduction and internal fixation and grafting of her left SI joint, while the ipsilateral pubic rami fractures were treated conservatively. She achieved union and pain free weight bearing 6 months postoperatively. Appropriate evaluation of the pathology and selection of the appropriate treatment in this elderly patient cohort is essential for a successful outcome. Experienced surgical team and individualized treatment approach are also vital to optimize the result of treatment.

Avascular necrosis of the femoral head (AVNFH) is relatively infrequent, but if undiagnosed or untreated, it may result in significant functional disability, and due to severe ongoing pain, a total hip replacement (THR) may be necessitated. Most cases are associated with trauma, but a number of established risk factors exist. Diagnosis can be challenging but relies on clinical history, physical examination, and radiology. X-ray and MRI are used to stage avascular necrosis (AVN) lesions, which in turn influence management decisions.We present a male in his early 40s, diagnosed with a right-sided AVNFH (Ficat-Arlet stage I) five years previously at another centre. A number of risk factors were identified, such as chronic alcohol abuse, smoking, obesity, and Klinefelter’s syndrome. A'watch and wait'approach was adopted, which included advice on reducing risk factors and commencement on aspirin and alendronic acid. However, his pain had recently increased, resulting in a significant reduction in mobility and an increased reliance on opiates. MRI demonstrated progression to Ficat-Arlet stage II, and the appearance of an additional smaller, second lesion located more medially in the same femoral head. Due to his symptom severity, he was offered a THR. In view of his young age, he came to our tertiary referral centre for a second opinion. He elected for a simultaneous dual surgical decompression of both AVN lesions and biological stimulation for bone-guided regeneration. This involved the delivery of growth factor (bone morphogenetic protein), progenitor cells, and a scaffold/matrix. At 36 months post-operatively, he continued to have the full, pain …

Published Date

2023/5/1

The ability to enhance fracture healing is paramount in modern orthopaedic trauma, particularly in the management of challenging cases including peri-prosthetic fractures, non-union and acute bone loss. Materials utilised in enhancing fracture healing should ideally be osteogenic, osteoinductive, osteoconductive, and facilitate vascular in-growth. Autologous bone graft remains the gold standard, providing all of these qualities. Limitations to this technique include low graft volume and donor site morbidity, with alternative techniques including the use of allograft or xenograft. Artificial scaffolds can provide an osteoconductive construct, however fail to provide an osteoinductive stimulus, and frequently have poor mechanical properties. Recombinant bone morphogenetic proteins can provide …

Periprosthetic acetabular fractures are rare but potentially devastating complications of total hip arthroplasty. As the number of total hip arthroplasties performed annually increases, so has the incidence of periprosthetic fractures, with the topic being spotlighted more frequently in the orthopaedic community. There is a particular sparsity of literature regarding periprosthetic acetabular fractures, with periprosthetic femoral fractures after total hip arthroplasty being traditionally far more commonly reported. This article aims to provide an up-to-date review of the epidemiology, risk factors, diagnostic challenges, classifications, and management strategies for periprosthetic acetabular fractures after total hip arthroplasty.

Reconstructive surgery of the clavicle using free vascularised fibula grafting (FVFG) is sometimes required for the management of severe bone loss or non-union. As the procedure is relatively rare, there is no universal agreement on the management and outcome. This systematic review aimed to first, identify the conditions for which FVFG has been applied; second, to gain an understanding of the surgical techniques used; and third, to report outcomes related to bone union, infection eradication, function and complications. A PRISMA strategy was used. Medline, Cochrane Central Register of Controlled Trials, Scopus and EMBASE library databases were interrogated using pre-defined MeSH terms and Boolean operators.

Reconstruction of infected long bone defects: Issues and Challenges

Authors

Costas Papakostidis,Peter V Giannoudis

Published Date

2023/3/1

Complex extremity trauma, commonly the result of high energy injury, is usually characterized by extensive soft tissue destruction and concomitant bone loss. These injuries, during their course of management are frequently compounded by infection and non-union. An infected non-union, particularly when involving the tibia, which is characterized by a deficient soft-tissue envelope, is challenging to treat [1]. These injuries pose major therapeutic challenges to the limb reconstruction surgeons as several critical issues should be adequately addressed in order to achieve osseous union with simultaneous eradication of the infection and restoration of reasonable limb function. These critical issues include amongst others, bone loss (either due to the initial injury or to the subsequent surgical debridement), precarious soft tissue coverage, failed previous internal fixation, draining sinuses, leg-length discrepancies …

Published Date

2023/12/1

Periarticular fractures are complex injuries affecting the joint articular surface, the subchondral area, the metaphyseal region, the surrounding soft tissue envelope and not infrequently the ligamentous structures.The management of these injuries has evolved over the years, from one stage to two stage procedures thus facilitating soft tissue resuscitation, adequate pre-operative planning and the use of biologics optimizing the conditions for definitive fixation for a successful long-term outcome. Provisional fixation constitutes an essential step in the surgical treatment of these fractures. Herein, the role of provisional fixation as well as strategies on how they should be applied are discussed. The aim is to revisit this important step of provisional fracture fixation since its introduction by Albin Lambotte, in the early 1900′s.

Published Date

2023/2/1

Distal femoral fractures in elderly or osteoporotic patients constitute a challenging injury, especially in the settings of fracture comminution or periprosthetic fractures. A recent trend in the treatment of these difficult injuries is the double fixation with a nail and a plate, a strategy that comes with advantages including faster weight-bearing and lower risk for non-union. Although biomechanical studies have demonstrated the superiority of nail-plate constructs, there is a paucity in the literature regarding the indications and results of treatment. A review of the literature to date was carried out to identify which group of patients would benefit the most from this type of reconstruction and to evaluate the clinical outcomes.

During the past decade, more and more large-scale pragmatic clinical trials have been carried out in orthopedic trauma surgery. This trend is fueled by the common belief that the larger the numbers in a trial, the broader the eligibility criteria, and the less strict the regimentation of local treatment standards by protocol, the more trustworthy the findings would be. However, it must also be taken into account that the precision of an outcome measurement does not depend on the sample size alone, but the homogeneity of the studied population. Consequently, a small trial with stringent entry and assessment criteria may offer similarly precise answers as a large trial with less strict entry and assessment criteria because of the basic mathematical correlation between standard deviation and standard error of the mean. There is now a lively and controversial debate about the role of randomized controlled trials (RCT) in an …

The management of patients with multiple injuries remains challenging. Patients presenting with comorbidities, such as diabetes mellitus, may have additional unpredictable outcomes with increased mortality. Therefore, we aim to investigate the impact of major trauma centres in the UK on the outcomes of polytrauma patients with diabetes. The Trauma Audit and Research Network was used to identify polytrauma patients presenting to centres in England and Wales between 2012 and 2019. In total, 32,345 patients were thereby included and divided into three groups: 2271 with diabetes, 16,319 with comorbidities other than diabetes and 13,755 who had no comorbidities. Despite an overall increase in diabetic prevalence compared to previously published data, mortality was reduced in all groups, but diabetic patient mortality remained higher than in the other groups. Interestingly, increasing Injury Severity Score (ISS) and age were associated with increasing mortality, whereas the presence of diabetes, even when taking into consideration age, ISS and Glasgow Coma Score, led to an increase in the prediction of mortality with an odds ratio of 1.36 (p < 0.0001). The prevalence of diabetes mellitus in polytrauma patients has increased, and diabetes remains an independent risk factor for mortality following polytrauma.

A prospective, feasibility, randomised study was performed to compare intramedullary versus extramedullary fixation of unstable pertrochanteric fractures and to assess the feasibility of including patients with dementia. From July 2016 to November 2017, 60 consecutive patients with an unstable pertrochanteric (OTA/AO 31-A2) fracture were randomized to either receive a short cephalomedullary nail (Endovis EBA2, Citieffe) or a dynamic hip screw (DHS, Zimmer Biomet). Primary feasibility measures included randomisation, recruitment, and retention rates. Secondary outcomes included peri-operative parameters, patient-reported outcomes and radiographic outcomes. Patients were followed-up at two, four, and twelve weeks. There was no difference in the randomisation rate between patients with and without cognitive impairment. Significantly more patients without cognitive impairment attended the 12-week follow-up. The overall recruitment rate was 0.9 patients per week. Patients treated with the nail had less pain at 2 weeks and less neck collapse, medialisation, and leg shortening at all time points. The rest of secondary outcomes were similar. Patients with dementia can successfully be enrolled in a randomised trial on hip fractures. Patients treated with the Endovis nail had lower levels of pain at two weeks and better radiographic outcomes.

Multiple myeloma (MM) shows constitutive activation of canonical and noncanonical nuclear factor κB (NF-κB) signaling via genetic mutations or tumor microenvironment (TME) stimulations. A subset of MM cell lines showed dependency for cell growth and survival on the canonical NF-κB transcription factor RELA alone, suggesting a critical role for a RELA-mediated biological program in MM pathogenesis. Here, we determined the RELA-dependent transcriptional program in MM cell lines and found the expression of the cell surface molecules interleukin-27 receptor-α (IL-27Rα) and the adhesion molecule JAM2 to be responsive to RELA at the messenger RNA and protein levels. IL-27Rα and JAM2 were expressed on primary MM cells at higher levels than on healthy long-lived plasma cells (PCs) in the bone marrow. IL-27 activated STAT1, and to a lesser extent STAT3, in MM cell lines and in PCs generated …

Non-union is the failure of a fracture to unite in a timely fashion with an incidence reported to range from 2%-10%[1]. The aetiology is often multifactorial, involving a complex interplay relating to the biological pre-requisites and mechanical environment, as well as the physiological state of the host [2]. It is believed that the evolution of fracture healing involves the participation and optimum interaction of the key players (growth factors, stem cells, osteoconductive scaffolds and adequate mechanical environment) according to the ‘diamond concept’[2]. There is a lack of current clinical treatment guidance on the topic, as well as varying definitions of non-union which further adds to the challenge of managing non-union.

High-energy fractures of the proximal tibia with extensive fragmentation of the posterolateral (PL) quadrant of the tibial plateau are challenging to manage. Herein, we present a review of the literature on the patterns and options of approach and fixation of the PL fragment of the tibial plateau to optimize the treatment of this specific injury pattern. We searched PubMed (1980–May 2020) to identify and summarize the most relevant articles evaluating both the morphology and treatment recommendations, including the choice of approach and fixation strategy, for the PL tibial plateau fracture. We found PL fragment can present in several patterns as a pure split, split depression, contained pure depression, and noncontained depression (rim crush), which are mostly determined by the position of the knee and the force magnitude applied during the course of the accident. Based on previous concepts described by …

Our aim was to systematically review literature of trauma related rotator cuff tears in order to evaluate the outcome and healing integrity in relation to time of surgery. Our research question was whether earlier surgical repair leads to superior functional results. This review was conducted according to PRISMA statement. A literature search of Pubmed, Embase, Cohrane was conducted, with two researchers assessing studies for eligibility and quality. A total of 20 studies, published between 1980 and 2019, met the inclusion criteria and were divided into two groups based on duration of symptoms before surgery. Group A comprised of studies in which duration was< 3 months and Group B> 3 months. Within each group there was a statistically significant improvement in the CS from pre-operative to post-operative outcome, but the improvement for Group A was statistically higher in comparison to Group B (P= 0.01). Nevertheless, there was no significant difference in the final outcome for the two groups (P= 0.29). The re-tear rate per 100 patients was calculated 28.5 (±7.2) for Group A, and 17.2 (±12.56) for Group B (P= 0.056). Our results suggest that functional outcome and tendon healing may not be valid arguments for early surgical repair. Therefore, repair of traumatic RCTs could be recommended whenever technically possible.

Background Long bone fractures display significant non-union rates, but the exact biological mechanisms implicated in this devastating complication remain unclear. The combination of osteogenetic and angiogenetic factors at the fracture site is an essential prerequisite for successful bone regeneration. The aim of this study is to investigate the results of the clinical implantation of growth factors for intraoperative enhancement of osteogenesis for the treatment of long bone fractures and non-unions. Methods A systematic literature review search was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines in the PubMed and Web of Science databases from the date of inception of each database through to 10 January 2022. Specific inclusion and exclusion criteria were applied in order to identify relevant studies reporting on the treatment of upper and lower limb long bone non-unions treated with osteoinductive or cellular factors. Results Overall, 18 studies met the inclusion criteria and examined the effectiveness of the application of Bone Morphogenetic Proteins-2 and -7 (BMPs), platelet rich plasma (PRP) and mesenchymal stem cells (MSCs). Despite the existence of limitations in the studies analysed (containing mixed groups of open and close fractures, different types of fractures, variability of treatment protocols, different selection criteria and follow-up periods amongst others), their overall effectiveness was found significantly increased in patients who received them compared with the controls (I2 = 60%, 95% CI = 1.59 [0.99–2.54], Z =1.93, p = 0.05).

The scoring system was developed based on the clinical experience of the authors carrying out this type of reconstructive surgery and the existing research evidence at that period of time. By attributing values to clinical features that we felt were important we included such parameters as bone quality, original fracture characteristics (closed or open), number of previous interventions, invasiveness of previous interventions, adequacy of previous surgery, bone alignment, presence of bone defect, state of the soft tissues, and the American Society of Anesthesiologists (ASA) grade of the patient. The severity of non-union was graded using a scale of 0 to 100, with a higher score indicating a greater severity. Moreover, based on the final score computed, the result …

Musculoskeletal trauma refers to injuries of the spine, pelvis and extremities and is primarily managed by Orthopaedic Surgeons. Its burden to society is tremendous and involves both direct costs (related to the healthcare provided) and indirect costs, such as the long-lasting consequences of physical and psychological impairment to citizens, loss of income and employment and therefore reduced taxpayer contributions. Currently, there are scarce statistics to estimate the scale of the problem, which is huge. If the numbers are not known, then prompt actions that will save money and provide optimal health care cannot be implemented. One solution could be National Trauma Registries: these are databases that collect such information in a systematic way. The EuroTARN project was started in 2005 to enable EU Member States to create such registries and to combine them at a Federal Level. It has stalled and needs political support to complete.

Traumatic bone defects represent a complex clinical scenario and a major cause of patient disability. Advances in fixation methods, bone reconstruction, soft tissue management, and antibiotics have led to an increase in limb salvage rates. Autogenous bone grafting remains the gold standard for small defects, while distraction osteogenesis, vascularized bone grafts and the induced membrane technique among others, offer solutions for the larger defects. Each method carries unique advantages and shortcomings.These debilitating injuries must be managed in specialized units with input from a multidisciplinary team.The rehabilitation may be prolonged, while the end result may be associated with a degree of residual functional impairment.

Critical-size long bone defects represent one of the major causes of fracture non-union and remain a significant challenge in orthopaedic surgery. Two-stage procedures such as a Masquelet technique demonstrate high level of success however their main disadvantage is the need for a second surgery, which is required to remove the non-resorbable cement spacer and to place the bone graft into the biological chamber formed by the ‘induced membrane’. Recent research efforts have therefore been dedicated towards the design, fabrication and testing of resorbable implants that could mimic the biological functions of the cement spacer and the induced membrane. Amongst the various manufacturing techniques used to fabricate these implants, three-dimensional (3D) printing and electrospinning methods have gained a significant momentum due their high-level controllability, scalable processing and relatively low …

With an ever-ageing population, the incidence of hip fractures is increasing worldwide. Increasing age is not just associated with increasing fractures but also increasing comorbidities and polypharmacy. Consequently, a large proportion of patients requiring hip fracture surgery (HFS) are also prescribed antiplatelet and anti-coagulant medication. There remains a clinical conundrum with regards to how such medications should affect surgery, namely with regards to anaesthetic options, timing of surgery, stopping and starting the medication as well as the need for reversal agents. Herein, we present the up-to-date evidence on HFS management in patients taking blood-thinning agents and provide a summary of recommendations based on the existing literature.

Articular fractures of the distal humerus in adults are challenging fractures requiring adequate surgical exposure for optimum reconstruction. Most commonly, an articular osteotomy of the olecranon is performed, but complications have been reported related to both creating and repairing the articular osteotomy. We describe the use of an extra-articular olecranon osteotomy for approaching articular fractures of the distal humerus. We highlight the surgical steps required to obtain adequate exposure facilitating anatomical reduction, stable fixation, and early range of motion of the elbow joint. This technique can be added to the surgeon's armamentarium for the management of these complex injuries. [Orthopedics. 2022;45(4):e220–e225.]

Treatment of fractures remains challenging and carries a high economical burden to both patients and society. In order to prevent some of the complications, the use of bone adhesives has been proposed, but up to date, bone adhesives are not part of the current clinical practice. Early results of use of bone cements and bone glues are promising, focusing in the areas of highly fragmented fractures, fixation of long bone fractures, filling bone voids and defects, promoting osseointegration, preventing non-union while maintaining the reduction of fracture fixation. This review aims to describe the state-of-the-art of the development, properties and use of adhesives in fracture treatment.

The first published surgical treatment of patella fracture was in 1841 by Dieffenbach who cut both the patellar and quadriceps tendons and used compressive bandage to oppose the fragments [1]. However, historically, American surgeon George McClellan is credited by later authors to be the first one who successfully internally fixed a patella fracture around 1838, using holes to pass a softiron wire to approximate the fragments, although earlier unsuccessful attempts resulting in patient death have also been reported [1]. Before the antiseptic era, many attempts focused on the use of the percutaneous “Malgaigne hooks” to approximate the fragments, with several authors reporting on modifications of the original 1843 device by Malgaigne, however this was complicated by high rates of infection leading to septic arthritis and death by septic shock [1].

Although I feel it is a little early to call time on the Major Trauma Centre, it is a reminder that any clinical service must adapt to the changing needs of the population they serve, and as highlighted, two areas stand out as targets for improvement, the fate of the elderly trauma patient, and the role of inter-hospital transfer in trauma. Elderly trauma patients are different to those that Major Trauma Centres were initially designed to serve. They have differing needs from the traditional multi-injured patient, they are frail and have high mortality from lesser injuries, and that mortality relates as much if not more, to their preexisting frailty and medical comorbidity as to their injury. Their needs are as much medical and social as surgical, and it is right to say that services need to …

Dicalcium Phosphate Dihydrate (DCPD) mineral scaffolds alone do not possess the mechanical flexibility, ease of physicochemical properties’ tuneability or suitable porosity required for regenerative bone scaffolds. Herein, we fabricated highly porous freeze-dried chitosan scaffolds embedded with different concentrations of Dicalcium Phosphate Dihydrate (DCPD) minerals, i.e., 0, 20, 30, 40 and 50 (wt)%. Increasing DCPD mineral concentration led to increased scaffold crystallinity, where the % crystallinity for CH, 20, 30, 40, and 50-DCPD scaffolds was determined to be 0.1, 20.6, 29.4, 38.8 and 69.9%, respectively. Reduction in scaffold pore size distributions was observed with increasing DCPD concentrations of 0 to 40 (wt)%; coalescence and close-ended pore formation were observed for 50-DCPD scaffolds. 50-DCPD scaffolds presented five times greater mechanical strength than the DCPD mineral-free scaffolds (CH). DCPD mineral enhanced cell proliferation for the 20, 30 and 40-DCPD scaffolds. 50-DCPD scaffolds presented reduced pore interconnectivity due to the coalescence of many pores in addition to the creation of closed-ended pores, which were found to hinder osteoblast cell proliferation.

The first Trauma and Orthopaedic unit dates back to 1780, originally dedicated to the treatment of children's deformities. The specialty has subsequently become multifaceted, with a plethora of subspecialty areas of which orthopaedic trauma is the most commonly practiced. Recently there has been a significant demand for an evidence base with more than 130,000 of the 162,000 publications in the last century occurring within the past 20 years. This narrative review will summarise some of the more landmark changes within orthopaedic trauma that have been made within the past 20 years, whilst also attempting to predict where the specialty will continue to develop as we move forward.
