An international instant-messaging journal club: a modern, fun and global approach to a traditional teaching tool.The aim of this study was to introduce a modern, engaging and easily accessible approach to medical education. A virtual journal club (VJC) was established for the orthopaedic trainees of Ethiopia using instant messaging via Viber. Group discussions included research articles, case reports and radiographs. In addition, senior participants posed quiz questions, with a leaderboard for best performance. Finally, a satisfaction survey was conducted using Google Forms. We have accumulated data from the first five months of educational activity with 73 participants. Seven articles were analysed and debated, covering a broad range of orthopaedic topics, with 56 messages per article on average and 60 quiz questions overall. Our survey received 20 responses, where 95% perceived the VJC as superior to the traditional journal club. Instant messaging is recommended as an educational tool, utilised as an effective VJC. It provides continuous interactive distance learning, without the restrictions of traditional methods.

A novel behavioural INTErvention to REduce Sitting Time in older adults undergoing orthopaedic surgery (INTEREST): results of a randomised-controlled feasibility study.Background: Osteoarthritis is a prevalent condition in older adults that causes many patients to require a hip or knee replacement. Reducing patients' sedentariness prior to surgery may improve physical function and post-operative outcomes. Methods: We conducted a pragmatic randomised-controlled feasibility study with 2:1 allocation into intervention or usual care groups. The intervention, based on Self-Determination Theory, involved techniques to reduce sedentary behaviour, including motivational interviewing, setting of behavioural goals, and more. The primary outcome was feasibility, assessed using mixed methods. We included exploratory measures to inform a future definitive trial, such as ActivPal3 accelerometry to measure movement, the Short Physical Performance Battery (SPPB), Basic Psychological Needs, and cardiometabolic biomarkers. Assessments were at baseline, 1-week pre-surgery, and 6-week post-surgery. Results: We recruited 35 participants aged ≥ 60 years approximately 8 weeks before hip or knee arthroplasty. Participant uptake rate was 14.2%, and retention rate 85.7%. Participants were very satisfied with the study which was found to be feasible with some modifications. Exploratory within-group comparisons found that the intervention has potential to improve SPPB by 0.71 points from baseline to pre-surgery, a clinically significant increase, and reduce sedentary time by up to 66 min d-1. Conclusion: In this older surgical population, it is feasible to use behavioural techniques to displace sedentary time to activity and to conduct a trial spanning the period of surgical intervention. This may improve physical function and surgical outcomes. The INTEREST intervention is now ready for evaluation in a full-scale randomised-controlled trial. Registration: This trial was registered on Clinicaltrials.gov on 13/11/2018. ID: NCT03740412.

A potential role of lymphangiogenesis for peripheral nerve injury and regeneration.Traumatic peripheral nerve injuries are common and socioeconomically highly relevant. Despite significant microsurgical advances, the results of surgical reconstruction are still far from optimal and the rate of life-long complications, such as impaired motor and sensory function or neuropathic pain, is high. Moreover, the regeneration of peripheral nerves is a complex and fragile process that is not yet completely understood. Hence, there is an urgent need to further elucidate the underlying biological mechanisms. Herein, we propose that the neural lymphatic vasculature and lymphangiogenesis play an essential role in both peripheral nerve injury and regeneration and discuss hypothetical mechanisms implementing the current literature. Finally, specific research approaches to test our hypothesis are introduced.

A daily Diagnostic multidisciplinary meeting to reduce time to definitive diagnosis in the context of primary bone and soft tissue sarcoma.Background and objectives: Cancer services are under increasing pressure to deliver waiting time targets. Our service has seen referral numbers increase to over 3000 per annum, with more than 80% coming from secondary care. In order to deliver a responsive service, the department has introduced a daily diagnostic multidisciplinary meeting (DMDT) with the aim being stratification of resources by directing rapid access to clinics and diagnostics to those felt to be at greatest risk of malignancy at the start of the pathway. It also aimed to improve communication with patients and referrers, consistency in decision making and deliver improved diagnostic turn-around times in a sustainable manner. An evaluation was undertaken to assess whether the introduction of the DMDT has improved the pathway, the primary endpoint being a reduction in time to definitive diagnosis (TTDD). Secondary endpoints included measurements of efficiency and whether there has been a reduction in variation in practice. Methods: Retrospective access to a prospective database over a 1-month period before (2015) and after (2018) the intervention. Results: The introduction of the DMDT has led to a reduction in TTDD (7 days). The service also has an added benefit in reducing average total patient miles travelled over the course of diagnosis by 22.68 miles. Conclusion: The introduction of a diagnostic MDT at the start of the pathway does lead to an improvement in service efficiency and a reduction in TTDD.

Proximal humerus fractures : a review of anatomy, classification, management strategies, and complicationsProximal humerus fractures are prevalent in older adults, particularly women, primarily due to osteoporosis and increased fall risk. These fractures often result from low-energy falls in elderly patients, while in younger individuals, they are more likely to occur with high-energy trauma, which may involve additional injuries to soft tissue and neurovascular structures. Proper anatomical understanding, including key structures and blood supply, is crucial for effective management and to prevent complications. Several classification systems assist in guiding treatment for proximal humerus fractures, including Codman's, Neer's, Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association (AO/OTA) system, and the Codman-Hertel system, which helps predict ischemia risk. Evaluation of proximal humerus fractures begins with Advanced Trauma Life Support (ATLS) protocols, emphasizing a thorough shoulder assessment, particularly focusing on skin integrity in elderly patients. Neurological and vascular examinations are essential due to the common occurrence of nerve injuries, especially involving the axillary nerve. Imaging typically includes multiple standard views, with advanced imaging reserved for complex cases and for assessing associated soft tissue injuries. Treatment options range from conservative management for stable fractures to surgical intervention for more complex cases. Surgical choices include techniques like fixation, nailing, and various arthroplasty options, with some procedures potentially offering advantages for older adults with bone quality or soft tissue challenges. Rehabilitation is a vital component of recovery, with emphasis on early mobility and gradual strengthening to restore function, especially in older patients. Complications following open reduction and internal fixation (ORIF) for proximal humerus fractures can include issues such as non-union, malunion, osteonecrosis, infection, joint stiffness, and fixation failure. In cases where non-union or fixation failure occurs, revision surgery or arthroplasty may be necessary. Joint stiffness may require further intervention if physical therapy is insufficient, while symptomatic osteonecrosis might also need surgical management. Malunion is generally better tolerated in older patients but may require correction in younger individuals. Other surgical options, such as hemiarthroplasty (HA) and reverse shoulder arthroplasty (RSA), share similar risks, including infection, fractures, complications at the tuberosity, stiffness, and instability. RSA may be favored when there are tuberosity or rotator cuff issues. Closed reduction with percutaneous pinning carries a high risk of pin migration and malunion, which can result in deformities, pain, and dysfunction. Proper anatomical knowledge is essential to avoid neurovascular injury and to manage common issues such as pin-site infections effectively.

Evaluation of Patient-Initiated Follow-Up (PIFU) service in a Fracture clinic : a comprehensive service evaluation and patient satisfaction auditBackground Outpatient clinics are increasingly challenged by high patient volumes and rising "did not attend" (DNA) rates, leading to extended wait times and declines in patient satisfaction. Traditional follow-up (FU) models with routinely scheduled appointments contribute to inefficiencies, as stable patients may attend unnecessary visits, thus straining clinic resources. The patient-initiated follow-up (PIFU) model offers an alternative where patients schedule appointments only when necessary. This study evaluates PIFU's efficacy in improving outpatient services and patient satisfaction by reducing routine appointments and prioritizing patient-driven follow-up. Methods This service evaluation and patient satisfaction audit was conducted at the fracture clinic of Royal Shrewsbury Hospital over three months (December 2023-March 2024). Out of 3828 patients seen, 203 were assigned to PIFU based on criteria indicating stable conditions with minimal follow-up requirements. The remaining patients were either scheduled for routine follow-ups or discharged. Data were collected retrospectively from clinic records, and a structured questionnaire assessed patient satisfaction with the PIFU service. Results Among the 203 patients assigned to PIFU, 183 (90.15%) patients received an informational leaflet, with all respondents finding it easy to understand. However, only 41 (20.2%) of patients utilized the PIFU service, primarily for concerns about pain, healing, or complications. Satisfaction among PIFU users was high, with 163 (80.3%) patients rating the service 5/5. Non-users mostly cited no perceived need for follow-up. Demographic analysis indicated that patients aged 40-60 were predominant (n=132; 65.02%) among the PIFU cohort. Conclusion The PIFU model demonstrated the potential to alleviate clinic workload by reducing routine follow-ups while maintaining high patient satisfaction. Although utilization rates were low, those who engaged found the service beneficial, suggesting PIFU's value for patients comfortable with self-management. Improved patient education may enhance engagement, supporting the broader implementation of PIFU in outpatient settings. Further research is warranted to explore barriers to patient-initiated follow-up and refine eligibility criteria for optimal outcomes.

Wide awake local anaesthesia no tourniquet surgery of the foot and ankle: a review of indications, technique, patient satisfaction, and complicationsWide-awake surgery of the hand was surrounded by a lot of apprehension, mainly over concerns around using epinephrine near digits and its potential to cause digital ischemia and necrosis. With multiple reports underlining its safety and effectiveness, it is now being widely adopted in hand and wrist surgery. The British Society for Surgery of the Hand has already published guidelines on operating outside of main theatres, with an emphasis on wide awake local anaesthesia no tourniquet (WALANT). However, the same cannot be said for its use in foot and ankle procedures. There have been a handful of reports describing WALANT in bony and soft tissue procedures of the foot and ankle, with varied success. We aim to describe the scope of WALANT in these procedures and explore in detail its current role in the domain of lower extremity wide-awake surgery.

Porcine submucosal extracellular matrix wrapping of the ulnar nerve in revision cubital tunnel surgeryThe wrapping technique aims to protect the nerve when the nerve bed is compromised or more commonly to prevent the recurrence of scar tethering following neurolysis. A wrap provides a physical barrier to scar and helps restore the paraneurial gliding layer. This study aimed to evaluate the results of the AxoGuard® nerve protector, a porcine-derived submucosal extracellular matrix (PECM), used as an adjunct in persistent or recurrent cubital tunnel syndrome (CuTS). This retrospective cohort study evaluated patients diagnosed, between 2012 and 2020, with neuropathic pain who underwent revision surgery. Patients were categorised into Group A (revision surgery only) and Group B (revision surgery and adjunctive PECM nerve wrapping). Disease severity was scored at the baseline and six months post-operatively using the McGowan classification. A linear regression model was used to assess the effect of wrapping the ulnar nerve on the clinical outcome at six months. Fifty-nine nerves were treated; among them, adjunctive PECM wrapping was used in 32 nerves. Disease severity at baseline was similar between the groups. After adjusting for differences in baseline characteristics, participants in Group B improved with a significant difference of 0.43 McGowan points over Group A (95% CI (0.01-0.86), p = 0.049). There were no implant-related complications. Group B improved with excellent or good outcomes in 84.4% patients at the final follow-up. Persistent or recurrent CuTS were associated with neuropathic pain and significant nerve scar tether. The use of PECM appears to lead to improved clinical symptoms, possibly by reducing adhesions and encouraging physiological glide. LEVEL OF EVIDENCE: Level III evidence.

The effect of injurious compression on the elastic, hyper-elastic and visco-elastic properties of porcine peripheral nerves.The aim of this study was to characterise the viscoelastic and hyper-elastic properties of the ulnar nerve before and after compression has been induced, in order to aid the understanding of how the mechanical properties of nerves are altered during nerve compression, a contributing factor to cubital tunnel syndrome. Ulnar nerves were dissected from porcine legs and tensile tested to 10% strain. The Young's modulus and Yeoh hyper-elastic model were used to evaluate the materials elastic and hyper-elastic properties respectively. Dynamic mechanical analysis (DMA) was used to evaluate the viscoelastic properties over a range of frequencies between 0.5 Hz and 38 Hz. The nerves were then compressed to 40% for 60 s and the same tests were carried out after compression. The nerves were stiffer after compression, the mean Young's modulus before was 0.181 MPa and increased to 0.601 MPa after compression. The mean shear modulus calculated from the Yeoh hyper-elastic model was also higher after compression increasing from 5 kPa to 7 kPa. After compression, these properties had significantly increased (p < 0.05). The DMA results showed that the nerves exhibit frequency dependent viscoelastic behaviour across all tested frequencies. The median values of storage modulus before compression ranged between 0.605 and 0.757 MPa across the frequencies and after compression between 1.161 MPa and 1.381 MPa. There was a larger range of median values for loss modulus, before compression, median values ranged between 0.073 MPa and 0.216 MPa and after compression from 0.165 MPa to 0.410 MPa. There was a significant increase in both storage and loss modulus after compression (p < 0.05). The mechanical properties of the nerve change following compression, however the response to decompression in vivo requires further evaluation to determine whether the observed changes persist, which may have implications for clinical recovery after surgical decompression in entrapment neuropathy.

The endocrinology of sarcopenia and frailty.Sarcopenia describes low muscle mass and strength associated with ageing, whilst reduced physical performance indicates the severity of the condition. It can happen independently of other medical conditions and can be a key feature of the frailty phenotype. Frailty is a syndrome of increased vulnerability to incomplete resolution of homeostasis, following a stressor event. Researchers have described the implications of hypothalamic pituitary dysregulation in the pathogenesis of both entities. This review summarizes the recent evidence in this area as well as other endocrine factors such as insulin resistance and vitamin D status and outlines current research priorities. We conducted searches to PubMed and Embase databases for articles, reviews and studies reporting new data on the interaction between hormones of the endocrine system and frailty and/ or sarcopenia in the last 5 years. Interventional studies, cohort studies, case-control studies and animal studies were included. Clinical trials register was also searched to identify ongoing relevant studies. Studies have given us insights into the complex relationships between factors such as anabolic hormones, glucocorticoids and vitamin D on muscle strength and performance and their involvement in ageing phenotypes. However, robust randomized controlled trials are needed to consolidate existing evidence in humans and inform clinical practice. Current evidence supports hormone replacement in patients with confirmed deficiencies, to optimize health and prevent complications. Hormone replacement has limited use for age-related conditions. Current interest is focused on muscle/bone/fat interactions and health outcomes in "sarcopenic obesity." A life-course approach to improving 'health-span' is advocated. Lifestyle factors such as nutrition and physical activity have important interactions with body composition, physical function and metabolic outcomes. Large-scale clinical trials will determine the efficacy and long-term safety of hormone supplementation in the management of sarcopenia and frailty.

Outcomes of free vascularized fibular grafts in treating massive forearm skeletal defectsIntroduction: Reconstructing long bone defects in the upper limbs, particularly the radius and ulna, poses significant challenges. These defects, resulting from trauma, tumors, infections, or congenital anomalies, require precise surgical intervention for functional restoration. Traditional non-vascularized autogenous bone grafts have limitations, such as resorption and limited biological activity. To address these challenges, free vascularized fibular grafts (FVFGs) have been developed, offering enhanced recovery by supplying nutrients and structural support, particularly in large defects or compromised vascularity. Materials and methods: This retrospective study reviewed patients with significant forearm skeletal defects treated with FVFGs at our institution from January 2008 to January 2019. Included were patients with radius or ulna defects exceeding 8 cm due to trauma, tumor excision, or non-union fractures. Data on demographics, clinical details, surgical techniques, and outcomes-including graft union time, complications, range of motion, and the disabilities of the arm, shoulder and hand (DASH) scores-were analyzed. Results: Eight patients, with a mean age of 27.6 years and an average defect length of 9.8 cm, were included. All patients achieved graft union within an average of 4 months, with no tumor recurrence or significant complications. Functional outcomes showed mean forearm pronation of 56.9 degrees, supination of 52.5 degrees, and a mean DASH score of 17.7. Conclusions: FVFG is a safe and effective technique for managing complex forearm bone defects, providing high union rates and good functional outcomes. It should be considered a primary option for large forearm skeletal defects.

The effect of video-assisted learning on pre-operative knowledge and satisfaction for total knee arthroplasty surgery: a randomised-controlled studyIntroduction: Traditionally, surgical procedures are explained through consultations between the surgeon and the patient to ensure informed consent. Patient education enhances engagement and knowledge, aiding informed decision-making. This study aimed to assess the effect of an educational video on preoperative patient knowledge and satisfaction in the context of total knee arthroplasty (TKA) as an adjunct to the consent process. Methods: A prospective randomized controlled study involving 100 patients in dedicated elective orthopedic units in UK-based hospitals was conducted. After consultation with a dedicated knee surgeon and a preoperative education day for TKA run by dedicated orthopedic nurse specialists, patients were randomized into one of two limbs (video vs no video) at a 1:1 ratio. The treatment group (video group) was shown a video about the principles and steps of the procedure, including the recovery time. Following this, a 10-point knowledge test was completed, and patients rated their satisfaction with the preoperative education on a scale of 0-10. Results: Patients in the video limb group had a significantly greater mean knowledge score and greater satisfaction with preoperative education than patients who did not view the video. The video group (n = 49) had a mean knowledge score of 8.73 +/- 0.159 compared to 7.68 +/- 0.281 for the nonvideo limb (n = 50) (p < 0.05). The video group had a mean satisfaction score of 9.00 +/- 0.123 compared to 8.40 +/- 0.121 for the nonvideo limb group (p < 0.05). Conclusion: Video-assisted consent in total knee arthroplasty improves preoperative knowledge and patient satisfaction when used as an adjunct in the consent process. A simple, standardized video, either pre- or post-consultation could reinforce information that the patient receives in a simple effective manner, allowing for true informed consent.

The British Orthopaedic Surgery Surveillance study: slipped capital femoral epiphysis: the epidemiology and two-year outcomes from a prospective cohort in Great Britain.Aims: The aim of this study was to inform the epidemiology and treatment of slipped capital femoral epiphysis (SCFE). Methods: This was an anonymized comprehensive cohort study, with a nested consented cohort, following the the Idea, Development, Exploration, Assessment, Long-term study (IDEAL) framework. A total of 143 of 144 hospitals treating SCFE in Great Britain participated over an 18-month period. Patients were cross-checked against national administrative data and potential missing patients were identified. Clinician-reported outcomes were collected until two years. Patient-reported outcome measures (PROMs) were collected for a subset of participants. Results: A total of 486 children (513 hips) were newly affected, with a median of two patients (interquartile range 0 to 4) per hospital. The annual incidence was 3.34 (95% confidence interval (CI) 3.01 to 3.67) per 100,000 six- to 18-year-olds. Time to diagnosis in stable disease was increased in severe deformity. There was considerable variation in surgical strategy among those unable to walk at diagnosis (66 urgent surgery vs 43 surgery after interval delay), those with severe radiological deformity (34 fixation with deformity correction vs 36 without correction) and those with unaffected opposite hips (120 prophylactic fixation vs 286 no fixation). Independent risk factors for avascular necrosis (AVN) were the inability of the child to walk at presentation to hospital (adjusted odds ratio (aOR) 4.4 (95% CI 1.7 to 11.4)) and surgical technique of open reduction and internal fixation (aOR 7.5 (95% CI 2.4 to 23.2)). Overall, 33 unaffected untreated opposite hips (11.5%) were treated for SCFE by two-year follow-up. Age was the only independent risk factor for contralateral SCFE, with age under 12.5 years the optimal cut-off to define 'at risk'. Of hips treated with prophylactic fixation, none had SCFE, though complications included femoral fracture, AVN, and revision surgery. PROMs demonstrated the marked impact on quality of life on the child because of SCFE. Conclusion: The experience of individual hospitals is limited and mechanisms to consolidate learning may enhance care. Diagnostic delays were common and radiological severity worsened with increasing time to diagnosis. There was unexplained variation in treatment, some of which exposes children to significant risks that should be evaluated through randomized controlled trials.

The British Orthopaedic Surgery Surveillance study: Perthes' disease: the epidemiology and two-year outcomes from a prospective cohort in Great Britain.Aims: The aim of this study was to evaluate the epidemiology and treatment of Perthes' disease of the hip. Methods: This was an anonymized comprehensive cohort study of Perthes' disease, with a nested consented cohort. A total of 143 of 144 hospitals treating children's hip disease in the UK participated over an 18-month period. Cases were cross-checked using a secondary independent reporting network of trainee surgeons to minimize those missing. Clinician-reported outcomes were collected until two years. Patient-reported outcome measures (PROMs) were collected for a subset of participants. Results: Overall, 371 children (396 hips) were newly affected by Perthes' disease arising from 63 hospitals, with a median of two patients (interquartile range 1.0 to 5.5) per hospital. The annual incidence was 2.48 patients (95% confidence interval (CI) 2.20 to 2.76) per 100,000 zero- to 14-year-olds. Of these, 117 hips (36.4%) were treated surgically. There was considerable variation in the treatment strategy, and an optimized decision tree identified joint stiffness and age above eight years as the key determinants for containment surgery. A total of 348 hips (88.5%) had outcomes to two years, of which 227 were in the late reossification stage for which a hip shape outcome (Stulberg grade) was assigned. The independent predictors of a poorer radiological outcome were female sex (odds ratio (OR) 2.27 (95% CI 1.19 to 4.35)), age above six years (OR 2.62 (95% CI (1.30 to 5.28)), and over 50% radiological collapse at inclusion (OR 2.19 (95% CI 0.99 to 4.83)). Surgery had no effect on radiological outcomes (OR 1.03 (95% CI 0.55 to 1.96)). PROMs indicated the marked effect of the disease on the child, which persisted at two years. Conclusion: Despite the frequency of containment surgery, we found no evidence of improved outcomes. There appears to be a sufficient case volume and community equipoise among surgeons to embark on a randomized clinical trial to definitively investigate the effectiveness of containment surgery.
