• Are displaced distal clavicle fractures associated with inferior clinical outcomes following nonoperative management? A systematic review

  Haque, Aziz (2024-08)

  Background: Management of displaced distal clavicle fractures remains a topic of discussion because of notoriously high nonunion rates, but there is little documented in the literature as to what effect this may have on patient-reported function. The aim of this systematic review was to look at nonoperative management following displaced distal clavicle fractures to determine union rates, complications, and patient-reported outcome measures. Methods: A review of the online databases MEDLINE and Embase was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Clinical studies that included a cohort of nonoperatively managed displaced distal clavicle fractures and reported on union rate, complications, and patient-reported functional scores were included. Results: Eleven studies were eligible for inclusion (2 randomized controlled trials, 1 prospective noncomparative cohort study, 5 retrospective comparative cohort studies, and 3 case series) with a total of 779 patients included in this review. Average union rate was 63.2% (22.2%-94.4%) in nonoperatively managed patients, compared with 96.3% (87.9%-100%) in operatively managed patients. The Constant-Murley score and Disabilities of the Arm, Shoulder, and Hand questionnaire were the most frequently used outcome measure tools. No study demonstrated any significant difference in any outcome measure when comparing nonoperative with operative treatment. Complication rate (including nonunion) in nonoperatively managed patients was 45.1%, with 11.1% requiring delayed surgery. Average complication rate in the operatively managed groups was 41.2%, with 40.1% requiring a second operation. Conclusion: Nonoperative management of displaced distal clavicle fractures results in higher nonunion rates, but shoulder function remains excellent, and risk of complications and delayed surgery are low. Decision making must take into account patient factors and expectations to provide high-quality, individualized care.
• The variation of anticoagulation prescribed in foot and ankle surgery in the UK - UK foot and ankle thrombo-embolism audit (UK-FATE)

  Houchen-Wolloff, Linzy; Mangwani, Jitendra (2024-06-26)

  Introduction: Venous thrombo-embolism (VTE) is a recognised complication of foot and ankle surgery. There are multiple possible anticoagulation treatments available in the UK to mitigate the risk of developing VTE. Our primary objective was to assess the variability of chemical anticoagulation prescribed in patients undergoing foot and ankle procedures. Methods: This was a UK-based national, multicenter, prospective audit spanning a collection duration of 9 months on all foot and ankle procedures, carried out in 68 UK centers between 1st June 2022 and 30th November 2022, with a further 3-month follow up period. All patients who underwent a foot and ankle surgical procedure (including Achilles tendon rupture treatment) were included in this study. Results: Data on a total of 13,569 patients was submitted. Following data cleansing, 11,363 patients were available for further analysis, with anticoagulation data available for 11,099 patients. There were eleven different chemical anticoagulation treatments recorded across the cohort. A total of 3630 (31.95 %) patients received no chemical anticoagulation. The patients receiving chemical anticoagulation medication could be split into 4 main groups. The most common chemical anticoagulation received was low molecular weight heparin (LMWH) (6303, 84.4 % of patients receiving chemical anticoagulation). Aspirin was given in 4.1 % (308 patients), a Factor Xa inhibitor in 10 % (744 patients) and other anticoagulants (e.g. Warfarin) in 1.5 % (114 patients). The overall VTE rate in this sub analysis of patients receiving chemical anticoagulation, was 1.1 % (83 cases out of 7469). There was no significant difference seen in incidence of VTE between types of anticoagulants, when confounding factors were considered. The duration of post-operative chemical prophylaxis used by participants for most chemical anticoagulants was 6 weeks (64.50 %). Conclusion: There was significant variability of chemical anticoagulants reported in the study, with five different categories of anticoagulants used (including no chemical anticoagulation), and none clearly superior/inferior. The duration of anticoagulation was consistent across types of thromboprophylaxis.
• Cortico-cancellous osseointegration into additively manufactured titanium implants using a load-bearing femoral ovine model

  Mangwani, Jitendra (2024-06-24)

  Introduction: Titanium-based implants can be used to fill voids in bone reconstruction surgery. Through additive manufacturing (AM), it is possible to produce titanium implants with osteoconductive properties such as high porosity and low stiffness. AM facilitates a level of design flexibility and personalization that is not feasible with traditional techniques. Methods: In this study, osseointegration into titanium alloy (Ti-6Al-4V) lattices was investigated for 12 weeks post-implantation using a novel bicortical load-bearing ovine model. The objective was to assess the safety and efficacy of AM-fabricated implants using two lattice structures of contrasting stiffness spanning the full width of the femoral condyle. Results: This was achieved by evaluating implant osseointegration and bone-implant contact properties by histomorphometry, scoring local implant tissue responses via histopathology, and micro-computed tomography reconstruction. Discussion: We found that Ti-6Al-4V implants facilitated widespread and extensive osseointegration, with bone maturation ongoing at the conclusion of the trial period. Following the implantation period, no adverse clinical indications that could be directly ascribed to the presence of the implanted device were identified, as determined by macroscopic and microscopic observation.
• Dedicated anticoagulation management protocols in fragility femoral fracture care - a source of significant variance and limited effectiveness in improving time to surgery: The hip and femoral fracture anticoagulation surgical timing evaluation (HASTE) study

  Aujla, Randeep; Sambhwani, Sharan (2024-06-19)

  Introduction: Approximately 20 % of femoral fragility fracture patients take anticoagulants, typically warfarin or Direct Oral AntiCoagulant (DOAC). These can impact timing of surgery affecting patient survival. Due to several possible approaches and numerous factors to consider in the preoperative workup of anticoagulated patients, potential for variations in clinical practice exist. Some hospitals employ dedicated anticoagulation management protocols to address this issue, and to improve time to surgery. This study aimed to determine the proportion of hospitals with such protocols, compare protocol guidance between hospitals, and evaluate the effectiveness of protocols in facilitating prompt surgery. Methods: Data was prospectively collected through a collaborative, multicentre approach involving hospitals across the UK. Femoral fragility fracture patients aged ≥60 years and admitted to hospital between 1st May to 31st July 2023 were included. Information from dedicated anticoagulation management protocols were collated on several domains relating to perioperative care including administration of reversal agents and instructions on timing of surgery as well as others. Logistic regression was used to evaluate effects of dedicated protocols on time to surgery. Results: Dedicated protocols for management of patients taking warfarin and DOACs were present at 41 (52.6 %) and 43 (55.1 %) hospitals respectively. For patients taking warfarin, 39/41 (95.1 %) protocols specified the dose of vitamin k and the most common was 5 milligrams intravenously (n=21). INR threshold values for proceeding to surgery varied between protocols; 1.5 (n=28), 1.8 (n=6), and 2 (n=6). For patients taking DOACs, 35/43 (81.4 %) and 8/43 (18.6 %) protocols advised timing of surgery based on renal function and absolute time from last dose respectively. Analysis of 10,197 patients from 78 hospitals showed fewer patients taking DOACs received surgery within 36 h of admission at hospitals with a dedicated protocol compared to those without (adjusted OR 0.73, 95% CI 0.54-0.99, p=0.040), while there were no differences among patients taking warfarin (adjusted OR 1.64, 95% CI 0.75-3.57, p=0.219). Conclusions: Around half of hospitals employed a dedicated anticoagulation management protocol for femoral fragility fracture patients, and substantial variation was observed in guidance between protocols. Dedicated protocols currently being used at hospitals were ineffective at improving the defined targets for time to surgery.
• Using Artificial Intelligence to predict outcomes of operatively managed neck of femur fractures

  Ashford, Robert (2024-06-30)

  Aims/Background Patients with neck of femur fractures present a tremendous public health problem that leads to a high incidence of death and dysfunction. An essential factor is the postoperative length of stay, which heavily impacts hospital costs and the quality of care. As an extension of traditional statistical methods, machine learning (ML) provides the possibility of accurately predicting the length of hospital stay. This review assesses how machine learning can effectively use healthcare data to predict the outcomes of patients with operatively managed neck of femurs. Methods A narrative literature review on the use of Artificial Intelligence to predict outcomes in the neck of femurs was undertaken to understand the field and critical considerations of its application. The papers and any relevant references were scrutinised using the specific inclusion and exclusion criteria to produce papers that were used in the analysis. Results Thirteen papers were used in the analysis. The critical themes recognised the different models, the 'backbox' conundrum, predictor identification, validation methodology and the need to improve efficiency and quality of care. Through reviewing the themes in this paper, current issues, and potential avenues of advancing the field are explored. Conclusions This review has demonstrated that the use of machine learning in Orthopaedic pathways is in its infancy. Further work is needed to leverage this technology effectively to improve outcomes.
• Incidence, demographics, characteristics and management of acute Achilles tendon rupture: An epidemiological study

  Faiza, Murtaza; Houchen-Wolloff, Linzy; Mangwani, Jitendra; Modha, Gayatri; Shepherd, Jenna (2024-06-21)

  Background: Achilles tendon rupture (ATR) account for 10.7% of all tendon and ligament injuries and causes lasting muscular deficits and have a profound impact on patients' quality of life. The incidence, characteristics and management of ATR in the United Kingdom (UK) is poorly understood. This investigation aims to understand the incidence of ATR in the UK. Methods: Prospective data collection of ATR incidence from a United Kingdom Emergency department. Retrospective review of management protocols and immobilisation duration from electronic medical records. Results: ATR incidence is 8 per 100,000 people per annum. Participants were predominately male (79.2%) and primarily reported a sporting mechanism of injury (65.2%). Mean immobilisation duration was 63.1 days. 97.1% were non-surgically managed post ATR. 46.2% of participants had experienced a previous ATR or Achilles tendinopathy prior to their current ATR. Conclusion: The incidence of ATR found was 8. cases per 100,000 people per annum. Most ATR were managed non-surgically in this cohort. The majority of ruptures occurred during sporting activity. Almost one quarter (23.3%) of individuals report Achilles pain prior to ATR.
• Characteristics of patients not receiving chemical thromboprophylaxis following foot and ankle surgery: Data from the multicenter, prospective UK Foot and Ankle Thrombo-Embolism Audit (UK-FATE)

  Mangwani, Jitendra (2024-06-13)

  Background: Although the rate of venous thromboembolism (VTE) after foot and ankle surgery is low, multiple factors influence risk for individual patients. Furthermore, there are no clear guidelines on which patients may benefit from chemical thromboprophylaxis. Our aim was to assess patients not treated with chemical thromboprophylaxis after foot and ankle surgery, and to report on their specific patient and surgical risk factors for VTE. Methods: This was a multicenter, prospective, national audit of patients undergoing foot and ankle surgery (including Achilles tendon ruptures) from 68 participating UK centers. The study was conducted between June 1, 2022, and November 30, 2022, with a further 3-month follow-up. Following data cleansing, 3309 patients were included who did not receive postoperative thromboprophylaxis. Results: Most patients were elective cases (2589 patients, 78.24%) with ASA grade I or II (2679 patients, 80.96%), fully weightbearing postoperatively (2752 patients, 83.17%), and either without ankle splintage, or splinted in a plantigrade boot (2797 patients, 84.53%). The VTE rate was 0.30% overall (11 cases), with no VTE-related mortality. No single demographic, surgical, or postoperative factor was associated with reduced risk of VTE. However, patients who had elective or trauma surgery not involving the ankle, who were ASA grade I or II and who were weightbearing immediately postoperatively (without splinting or in a plantigrade boot) had a VTE rate of 0.05% (1 of 1819 patients), compared with 0.67% (10 of 1490 patients, P = .002). Conclusion: Patients not receiving chemical thromboprophylaxis had a low incidence of symptomatic VTE, although they do represent a curated group considered lower risk. Within this group we describe characteristics associated with a substantially lower risk of VTE. All patients should be assessed on an individual basis, and further work is required to substantiate our findings.
• The impact of anticoagulant medications on fragility femur fracture care: The hip and femoral fracture anticoagulation surgical timing evaluation (HASTE) study

  Aujla, Randeep; Sambhwani, Sharan (2024-06)

  Introduction: Due to their hypocoagulable state on presentation, anticoagulated patients with femoral fragility fractures typically experience delays to surgery. There are no large, multicentre studies previously carried out within the United Kingdom (UK) evaluating the impact of anticoagulant use in this patient population. This study aimed to evaluate the current epidemiology and compare the perioperative management of anticoagulated and non-anticoagulated femoral fragility fracture patients. Methods: Data was prospectively collected through a collaborative, multicentre approach involving hospitals across the United Kingdom. Femoral fragility fracture patients aged ≥60 years and admitted to hospital between 1st May to 31st July 2023 were included. Main outcomes under investigation included time to surgery, receipt of blood transfusion between admission and 48 h following surgery, length of stay, and 30-day mortality. These were assessed using multivariable linear and logistic regression, and Cox proportional hazards models. Only data from hospitals ≥90 % case ascertainment with reference to figures from the National Hip Fracture Database (NHFD) were analysed. Results: Data on 10,197 patients from 78 hospitals were analysed. 18.5 % of patients were taking anticoagulants. Compared to non-anticoagulated patients, time to surgery was longer by 7.59 h (95 %CI 4.83-10.36; p < 0.001). 42.41 % of anticoagulated patients received surgery within 36 h (OR 0.54, 95 %CI 0.48-0.60, p < 0.001). Differences in time to surgery were similar between countries however there was some variation across units. There were no differences in blood transfusion and length of stay between groups (OR 1.03, 95 %CI 0.88-1.22, p = 0.646 and 0.22 days, 95 %CI -0.45-0.89; p = 0.887 respectively). Mortality within 30 days of admission was higher in anticoagulated patients (HR 1.27, 95 %CI 1.03-1.57, p = 0.026). Conclusions: Anticoagulated femoral fragility fracture patients comprise a substantial number of patients, and experience relatively longer delays to surgery with less than half receiving surgery within 36 h of admission. This may have resulted in their comparatively higher mortality rate. Inclusion of anticoagulation status in the minimum data set for the NHFD to enable routine auditing of performance, and development of a national guideline on the management of this growing and emerging patient group is likely to help standardise practice in this area and improve outcomes.
• A protocol for the conduct of a multicentre, prospective, randomized superiority trial of surgical versus non-surgical interventions for humeral shaft fractures

  Singh, Harvinder (2024-04-22)

  Aims: Fractures of the humeral shaft represent 3% to 5% of all fractures. The most common treatment for isolated humeral diaphysis fractures in the UK is non-operative using functional bracing, which carries a low risk of complications, but is associated with a longer healing time and a greater risk of nonunion than surgery. There is an increasing trend to surgical treatment, which may lead to quicker functional recovery and lower rates of fracture nonunion than functional bracing. However, surgery carries inherent risk, including infection, bleeding, and nerve damage. The aim of this trial is to evaluate the clinical and cost-effectiveness of functional bracing compared to surgical fixation for the treatment of humeral shaft fractures. Methods: The HUmeral SHaft (HUSH) fracture study is a multicentre, prospective randomized superiority trial of surgical versus non-surgical interventions for humeral shaft fractures in adult patients. Participants will be randomized to receive either functional bracing or surgery. With 334 participants, the trial will have 90% power to detect a clinically important difference for the Disabilities of the Arm, Shoulder and Hand questionnaire score, assuming 20% loss to follow-up. Secondary outcomes will include function, pain, quality of life, complications, cost-effectiveness, time off work, and ability to drive. Discussion: The results of this trial will provide evidence regarding clinical and cost-effectiveness between surgical and non-surgical treatment of humeral shaft fractures. Ethical approval has been obtained from East of England - Cambridge Central Research Ethics Committee. Publication is anticipated to occur in 2024.
• Comparison of interventions for lateral elbow tendinopathy: A systematic review and network meta-analysis for patient-rated tennis elbow evaluation pain outcome

  Dhingra, Mohit; Lowdon, Hamish; Singh, Harvinder Pal (2024-04-27)

  Purpose: There is controversy regarding the optimal treatment for lateral elbow tendinopathy (LET), and not all available treatment options have been compared directly with placebo/control. A network meta-analysis was conducted to compare the effectiveness of different LET treatments directly and indirectly against control/placebo based on a validated outcome, the Patient-Rated Tennis Elbow Evaluation (PRTEE) pain score. Methods: Randomized, controlled trials comparing different treatment methods for LET were included, provided they reported outcome data using the PRTEE pain score. A network meta-analysis with random effect was used to combine direct and indirect evidence between treatments compared with placebo in the short term (up to six weeks) and midterm (more than six weeks and up to six months) after intervention. Results: Thirteen studies with 12 comparators including control/placebo were eligible. The results indicated no significant improvement in PRTEE pain score in the short term across all treatments compared with control/placebo. In the midterm, physiotherapy/exercise showed benefit against placebo (mean difference: -4.32, 95% confidence interval: -7.58 and -1.07). Although steroid injections, dry needling, and autologous blood also exhibited potential treatment effects, it is crucial for the clinician to consider certain pitfalls when considering these treatments. The limited number of small studies and paucity of data call for caution in interpreting the results and need for further evidence. Conclusions: Patients should be informed that there is currently no strong evidence that any treatment produces more rapid improvement in pain symptoms when compared with control/placebo in the short and medium terms. Type of study/level of evidence: Therapeutic I.
• The paradox of haemodialysis: the lived experience of the clocked treatment of chronic illness

  Burton, James O; Hull, Katherine L (2024-03)

  Studies exploring the relationship between time and chronic illness have generally focused on measurable aspects of time, also known as linear time. Linear time follows a predictable, sequential order of past, present and future; measured using a clock and predicated on normative assumptions. Sociological concepts addressing lifecourse disruption following diagnosis of chronic illness have served to enhance the understanding of lived experience. To understand the nuanced relationship between time and chronic illness, however, requires further exploration. Here, we show how the implicit assumptions of linear time meet in tension with the lived experience of chronic illness. We draw on interviews and photovoice work with people with end-stage kidney disease in receipt of in-centre-daytime haemodialysis to show how the clocked treatment of chronic illness disrupts experiences of time. Drawing on concepts of 'crip' and 'chronic' time we argue that clocked treatment and the lived experience of chronic illness converge at a paradox whereby clocked treatment allows for the continuation of linear time yet limits freedom. We use the concept of 'crip time' to challenge the normative assumptions implicit within linear concepts of time and argue that the understanding of chronic illness and its treatment would benefit from a 'cripped' starting point.
• Advancements in De Quervain tenosynovitis management: a comprehensive network meta-analysis

  Dhingra, Mohit; Hall, Melinda; Pradhan, Akhilesh (2024-04-12)

  Purpose: This study presents a network meta-analysis aimed at evaluating nonsurgical treatment modalities for De Quervain tenosynovitis. The primary objective was to assess the comparative effectiveness of nonsurgical treatment options. Methods: The systematic review was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Searches were performed in multiple databases, and studies meeting predefined criteria were included. Data extraction, risk of bias assessment, and statistical analysis were carried out to compare treatment modalities. The analysis was categorized into short-term (within six weeks), medium-term (six weeks up to six months), and long-term (one year) follow-up. Results: The analysis included 14 randomized controlled trials encompassing various treatment modalities for De Quervain tenosynovitis. In the short-term, extracorporeal shockwave therapy demonstrated statistically significant improvement in visual analog scale pain scores compared with placebo. Extracorporeal shockwave therapy also ranked highest in the treatment options based on its treatment effects. Corticosteroid injections (CSIs) combined with casting and laser therapy with orthosis showed favorable outcomes. Corticosteroid injection alone, platelet-rich plasma injections alone, acupuncture, and orthosis alone did not significantly differ from placebo in visual analog scale pain score. In the medium-term, extracorporeal shockwave therapy remained the top-ranking option for visual analog scale pain score, followed by CSI with casting. In the long-term (one year), CSI alone and platelet-rich plasma injections demonstrated sustained pain relief. Combining CSI with orthosis also appeared promising when compared with CSI alone. Conclusions: Corticosteroid injection with a short duration of immobilization remains the primary and effective treatment for De Quervain tenosynovitis. Extracorporeal shockwave therapy can be considered a secondary option. Alternative treatment modalities, such as isolated therapeutic injection, should be approached with caution because they did not show substantial benefits over placebo.
• The economic and resource burden of e-scooter-related orthopaedic injuries: A district general hospital's experience

  Antonik, M; Sankar, S; Shepherd, J; Hassan, S (2024-03-11)

  Purpose: Electric scooters (e-scooters) are an increasingly popular method of transportation worldwide. However, there are concerns regarding their safety, specifically with regards to orthopaedic injuries. We aimed to investigate the overall burden and financial impact on orthopaedic services as a result of e-scooter-related orthopaedic injuries. Methods: We retrospectively identified all e-scooter-related injuries requiring orthopaedic admission or surgical intervention in a large District General Hospital in England over a 16-month period between September 2020 and December 2021. Injuries sustained, surgical management, inpatient stay and resources used were calculated. Results: Seventy-nine patients presented with orthopaedic injuries as a result of e-scooter transportation with a mean age of 30.1 years (SD 11.6), of which 62 were males and 17 were females. A total of 86 individual orthopaedic injuries were sustained, with fractures being the most common type of injury. Of these, 23 patients required 28 individual surgical procedures. The combined theatre and recovery time of these procedures was 5500 min, while isolated operating time was 2088 min. The total cost of theatre running time for these patients was estimated at £77,000. A total of 17 patients required hospital admission under Trauma and Orthopaedics, which accounted for total combined stay of 99 days with a mean length of stay of 5.8 days. Conclusion: While there are potential environmental benefits to e-scooters, we demonstrate the risks of injury associated with their use and the associated increased burden to the healthcare system through additional emergency attendances, frequent outpatient clinic appointments, surgical procedures, and hospital inpatient admissions.
• Flexor Injury Rehabilitation Splint Trial (FIRST): protocol for a pragmatic randomised controlled trial comparing three splints for finger flexor tendon repairs

  Dias, Joseph (2024-03-16)

  Background: Without surgical repair, flexor tendon injuries do not heal and patients' ability to bend fingers and grip objects is impaired. However, flexor tendon repair surgery also requires optimal rehabilitation. There are currently three custom-made splints used in the rehabilitation of zone I/II flexor tendon repairs, each with different assumed harm/benefit profiles: the dorsal forearm and hand-based splint (long), the Manchester short splint (short), and the relative motion flexion splint (mini). There is, however, no robust evidence as to which splint, if any, is most clinical or cost effective. The Flexor Injury Rehabilitation Splint Trial (FIRST) was designed to address this evidence gap. Methods: FIRST is a parallel group, superiority, analyst-blind, multi-centre, individual participant-randomised controlled trial. Participants will be assigned 1:1:1 to receive either the long, short, or mini splint. We aim to recruit 429 participants undergoing rehabilitation following zone I/II flexor tendon repair surgery. Potential participants will initially be identified prior to surgery, in NHS hand clinics across the UK, and consented and randomised at their splint fitting appointment post-surgery. The primary outcome will be the mean post-randomisation score on the patient-reported wrist and hand evaluation measure (PRWHE), assessed at 6, 12, 26, and 52 weeks post randomisation. Secondary outcome measures include blinded grip strength and active range of movement (AROM) assessments, adverse events, adherence to the splinting protocol (measured via temperature sensors inserted into the splints), quality of life assessment, and further patient-reported outcomes. An economic evaluation will assess the cost-effectiveness of each splint, and a qualitative sub-study will evaluate participants' preferences for, and experiences of wearing, the splints. Furthermore, a mediation analysis will determine the relationship between patient preferences, splint adherence, and splint effectiveness. Discussion: FIRST will compare the three splints with respect to clinical efficacy, complications, quality of life and cost-effectiveness. FIRST is a pragmatic trial which will recruit from 26 NHS sites to allow findings to be generalisable to current clinical practice in the UK. It will also provide significant insights into patient experiences of splint wear and how adherence to splinting may impact outcomes. Trial registration: ISRCTN: 10236011.
• Frequency and reporting of complications after Dupuytren's contracture interventions: a systematic review and meta-analysis

  Dias, J; Divall, P; Kulkarni, K; Raval, P

  Introduction: Numerous complications are reported following interventions for Dupuytren's contracture; however, their incidence, management, and outcomes remain poorly reported. The aims of this review were to report the proportions of complications, compare likelihood of complications between interventions, and evaluate reporting of complications, including assessment, grading, management, and subsequent reporting of their impact on patient outcomes. Methods: Extracted data included patient demographics, intervention details, complications, their management, and final outcomes. Analysis of descriptive data enabled review of complications reporting. Meta-analysis(MA) of non-comparative datasets enabled estimation of proportions of patients experiencing complications. Network meta-analysis(NMA) of comparative studies estimated the relative occurrence of complications between interventions. Risk of bias analysis was performed. Results: 26 studies, comprising 10,831 patients, were included. Interventions included collagenase injection, percutaneous needle fasciotomy(PNF), limited fasciectomy(LF), open fasciotomy(OF), and dermofasciectomy(DF). Overall quality and consistency of outcomes reporting was poor. MA enabled estimates of probabilities for three common complications(infection, nerve injury, complex regional pain syndrome(CRPS)) across all interventions; the reported rates for LF were 4.5% for infection, 3% for nerve injury, and 3.3% for CRPS. As the commonest intervention, LF was used as the reference intervention for comparison of the commonest complications via NMA, including haematoma [OF OR 0.450(0.277, 0.695); PNF OR 0.245(0.114, 0.457)], infection [PNF OR 0.2(0.0287, 0.690); DF OR 2.02(1.02, 3.74)], and neuropraxia [PNF OR 0.0926(0.00553, 0.737)]. We noted that the complication incidence was higher the more invasive the intervention. Conclusions: There was limited reporting of complication occurrence, management, and outcomes following interventions, contributing to a gap in information for informed patient consent. MA was possible for reporting of proportions for infection, nerve injury, and CRPS across interventions. NMA enabled direct comparison of the six commonest complications between interventions. These findings can guide intervention selection. Improving consistency and quality in complications reporting is essential to aid counselling of patients regarding the true rates and consequences of the risks of interventions. Type of study/level of evidence: 2.
• Early and 1-year mortality of native geriatric distal femur fractures: A systematic review and time-to-event meta-analysis

  Srinivasan, Ananth (2024-02-23)

  Purpose: Distal femur fractures (DFF) account for 6% of all femoral fractures and predominate in females. The current 1-year mortality of DFF is currently reported to be between 10 and 38%, a wide margin, and confounded by multiple factors including age, high energy mechanisms, pathological and periprosthetic fractures. The purpose of this study was to assess and determine all-cause mortality following geriatric native distal femur fractures at 30 days, six months and one year. Methods: - The databases Cochrane CENTRAL, MEDLINE, EMBASE and NHS NICE Healthcare Databases Advanced Search Interface were searched in accordance with PRISMA guidelines. Original research articles relevant to mortality outcomes in native geriatric distal femur fractures following low energy trauma were included. A time-to-event data meta-analysis model was used to estimate pooled 30-day, six month and one-year mortality. A random effects meta-regression model was performed to assess potential sources of heterogeneity when studies reported on factors affecting the mortality observed in patients with geriatric distal femur fractures. Results: - Thirteen studies were included in the meta-analysis with a mean age of 79.6 years. Eight studies reported the 30-day mortality of distal femur fractures in patients as a pooled estimate of 8.14%. Pooled estimate for 6-month mortality reported was 19.5% and the one-year mortality reported by ten studies was 26.10%. Time-to-event modelling showed that risk of mortality at one year in elderly patients with distal femur fractures was significantly higher HR = 4.31 (p < 0.001). When evaluating prognostic predictors, age and Type C fracture were predictive of highest mortality rates. Conclusions: - This study is the first meta-analysis to evaluate the early and long-term mortality observed in elderly patients presenting with native distal femoral fractures. Through our results we have shown the quantifiable impact patient age and fracture configuration has on one-year mortality in this patient cohort.

  How long is the arm immobilised after a conservatively managed displaced proximal humerus fracture and does early mobilisation effect complication rates: A systematic review

  Tunnicliffe, Helen; Divall, Pip; Singh, Harvinder (2024-03-21)

  Background: Conservative management of displaced proximal humerus fractures involves a period of rest in a sling followed by physiotherapy. The aim of this review is to provide a narrative synthesis of how long immobilisation is used, types of slings, when and how exercises are introduced, and if complications may be associated with these components. Method: A systematic search of the literature was undertaken. Two researchers screened relevant articles using Covidence software, with a third reviewer consulted for consensus. Data was extracted and a narrative synthesis is presented. Results: Thirty-nine studies were included (3059 studies screened, 159 full-text reviews). This included a cohort of 2664 patients with a mean age of 70.9. Time immobilised in sling ranged from 1 to 6 weeks. Sling types were variable and were grouped into low, medium and higher levels of support. Exercises were introduced at variable timescales tending to introduce passive and pendular exercises first. Complications were reported in 243 incidences (9.1%). Discussion: There was vast variation in how long patients were immobilised for, types of slings used and when and how exercises were introduced and progressed. No relationship was found between complications and these components. Research to identify the most effective approach is required.
• Modified Mason-Allen vs two simple stitch fixation for medial meniscus posterior root tears: a systematic review and meta-analysis

  Aujla, Randeep; Boksh, Khalis; Elbashir, Mohamed (2024-01-23)

  Background: Various suture configurations are available for medial meniscus posterior root tear (MMPRT) repair. The modified Mason-Allen (MMA) technique has been proposed as a refixation technique for MMPRT instead of the conventional 2 simple stitches (TSS). This is in view of its superior biomechanical characteristics. Purpose: To perform a systematic review and meta-analysis to compare MMA and TSS configuration techniques for MMPRT repair and identify any differences between the 2 techniques in terms of clinical outcomes, medial meniscal extrusion (MME), and postoperative healing. Study design: Meta-analysis; Level of evidence, 4. Methods: The Cochrane Controlled Register of Trials, PubMed, Medline, and Embase databases were used to perform a systematic review and meta-analysis using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria with the following search terms: ("meniscus" OR "meniscal injuries") AND ("Mason-Allen" OR "simple stitch" OR "suture techniques"). Data pertaining to all patient-reported outcome measures, postoperative complications, MME, postoperative healing, cartilage degeneration, and progression of knee osteoarthritis were extracted from each study. The pooled outcome data were analyzed using random- and fixed-effects models. Results: After abstract and full-text screening, 6 clinical studies were included. In total, there were 291 patients; 160 underwent MMA fixation, and 131 underwent the TSS technique. The majority of studies had similar surgical techniques regarding repair technique, suture material, tibial fixation, and number and position of tibial tunnels. There were no differences between the groups in terms of patient-reported outcome measures at 14.2 months. Both techniques were also similar in the degree of postoperative MME and meniscal healing. Conclusion: Both suture configurations were equivalent in terms of clinical outcomes, the extent of meniscal extrusion, and postoperative healing. The TSS technique may offer advantages in terms of faster learning curve and shorter operative time. However, randomized controlled trials with large sample sizes, longer follow-up and assessment of chondral degeneration, and presence of knee osteoarthritis are required to assess whether a true difference exists, as the majority of included studies were limited by their retrospective design.
• Learning curve of total ankle arthroplasty: a systematic review

  Arshad, Zaki; Haq, Ibrahim I; Bhatia, Maneesh (2024-02)

  Introduction: Together with ankle arthrodesis, total ankle arthroplasty is now accepted as a first-line intervention in the management of end-stage arthritis of the ankle. The evidence regarding how outcomes are affected by surgeon experience is inconsistent; we performed a systematic review to evaluate the effect of a learning curve in total ankle arthroplasty outcomes. Methods: An electronic database search was performed in PubMed, Embase, ISI Web of Science and Cochrane trials. Two reviewers independently conducted a two-stage title/abstract and full text screening. English-language original research studies comparing patient-reported outcome measures (PROMs), complication/revision rates, operative time, length of stay or radiation exposure according to surgeon experience were included. Quality assessment was performed using the methodological index for non-randomised studies. Results: All but one included study report either improved PROMs, reduced complication/revision rate, reduced hospital stay length/operative time or reduced radiation exposure with increasing surgeon experience. However, the majority of these findings lack statistical significance. Two studies assessing the plateau of the learning curve report a wide range of plateau thresholds between 9 and 39 cases. Conclusion: This review finds a largely non-significant trend towards improvements in PROMs, complication, and revision rates with improved surgeon experience. The lack of statistical significance in a number of studies may be partially explained by methodological flaws, with more suitably designed studies reporting significant improvements. Future research into the effect of advancements in implant design and insertion guides is required to further characterise the magnitude of the learning curve and guide both mitigation and learning strategies.
• The STAR care pathway for patients with pain at 3 months after total knee replacement: a multicentre, pragmatic, randomised, controlled trial

  Esler, Colin (2022-01-28)

  Background: Approximately 20% of people experience chronic pain after total knee replacement, but effective treatments are not available. We aimed to evaluate the clinical effectiveness and cost-effectiveness of a new care pathway for chronic pain after total knee replacement. Methods: We did an unmasked, parallel group, pragmatic, superiority, randomised, controlled trial at eight UK National Health Service (NHS) hospitals. People with chronic pain at 3 months after total knee replacement surgery were randomly assigned (2:1) to the Support and Treatment After Replacement (STAR) care pathway plus usual care, or to usual care alone. The STAR intervention aimed to identify underlying causes of chronic pain and enable onward referrals for targeted treatment through a 3-month post-surgery assessment with an extended scope practitioner and telephone follow-up over 12 months. Co-primary outcomes were self-reported pain severity and pain interference in the replaced knee, assessed with the Brief Pain Inventory (BPI) pain severity and interference scales at 12 months (scored 0-10, best to worst) and analysed on an as-randomised basis. Resource use, collected from electronic hospital records and participants, was valued with UK reference costs. Quality-adjusted life-years (QALYs) were calculated from EQ-5D-5L responses. This trial is registered with ISRCTN, ISRCTN92545361. Findings: Between Sept 6, 2016, and May 31, 2019, 363 participants were randomly assigned to receive the intervention plus usual care (n=242) or to receive usual care alone (n=121). Participants had a median age of 67 years (IQR 61 to 73), 217 (60%) of 363 were female, and 335 (92%) were White. 313 (86%) patients provided follow-up data at 12 months after randomisation (213 assigned to the intervention plus usual care and 100 assigned to usual care alone). At 12 months, the mean between-group difference in the BPI severity score was -0·65 (95% CI -1·17 to -0·13; p=0·014) and the mean between-group difference in the BPI interference score was -0·68 (-1·29 to -0·08; p=0·026), both favouring the intervention. From an NHS and personal social services perspective, the intervention was cost-effective (greater improvement with lower cost), with an incremental net monetary benefit of £1256 (95% CI 164 to 2348) at £20 000 per QALY threshold. One adverse reaction of participant distress was reported in the intervention group. Interpretation: STAR is a clinically effective and cost-effective intervention to improve pain outcomes over 1 year for people with chronic pain at 3 months after total knee replacement surgery.
