Aims. The underlying natural history of suspected scaphoid fractures (SSFs) is unclear and assumed poor. There is an urgent requirement to develop the literature around SSFs to quantify the actual prevalence of intervention following SSF. Defining the risk of intervention following SSF may influence the need for widespread surveillance and screening of SSF injuries, and could influence medicolegal actions around missed scaphoid fractures. Methods. Data on SSF were retrospectively gathered from virtual fracture clinics (VFCs) across a large Scottish Health Board over a four-year period, from 1 January 2018 to 31 December 2021. The Bluespier Electronic Patient Record System identified any surgical procedure being undertaken in relation to a scaphoid injury over the same time period. Isolating patients who underwent surgical intervention for SSF was performed by cross-referencing the unique patient Community Health Index number for patients who underwent these scaphoid procedures with those seen at VFCs for SSF over this four-year period. Results. In total, 1,739 patients were identified as having had a SSF. Five patients (0.28%) underwent early open reduction and internal fixation (ORIF). One patient (0.06%) developed a nonunion and underwent ORIF with bone grafting. All six patients undergoing surgery were male (p = 0.005). The overall rate of intervention following a SSF was 0.35%. The early intervention rate in those undergoing primary MRI was one (0.36%), compared with three in those without (0.27%) (p > 0.576). Conclusion. Surgical intervention was rare following a SSF and was not required in females. A primary MRI policy did not appear to be associated with any change in primary or secondary intervention. These data are the first and largest in recent literature to quantify the prevalence of surgical intervention following a SSF, and may be used to guide surveillance and screening pathways as well as define medicolegal risk involved in missing a true fracture in SSFs.

Aims. The aim of this retrospective study was to evaluate the rate of conversion to surgical release after a steroid injection in patients with a trigger finger, and to analyze which patient- and trigger finger-related factors affect the outcome of an injection. Methods. The medical records of 500 patients (754 fingers) treated for one or more trigger fingers with a steroid injection or with surgical release, between 1 January 2016 and 1 April 2020 with a follow-up of 12 months, were analyzed. Conversion to surgical release was recorded as an unsuccessful treatment after an injection. The effect of patient- and trigger finger-related characteristics on the outcome of an injection was assessed using stepwise manual backward multivariate logistic regression analysis. Results. Treatment with an injection was unsuccessful in 230 fingers (37.9%). Female sex (odds ratio (OR) 1.87 (95% confidence interval (CI) 1.21 to 2.88)), Quinnell stage IV (OR 16.01 (95% CI 1.66 to 154.0)), heavy physical work (OR 1.60 (95% CI 0.96 to 2.67)), a third steroid injection (OR 2.02 (95% CI 1.06 to 3.88)), and having carpal tunnel syndrome (OR 1.59 (95% CI 0.98 to 2.59)) were associated with a higher risk of conversion to surgical release. In contrast, an older age (OR 0.98 (95% CI 0.96 to 0.99)), smoking (OR 0.39 (95% CI 0.24 to 0.64)), and polypharmacy (OR 0.39, CI 0.12 to 1.12) were associated with a lower risk of conversion. The regression model predicted 15.6% of the variance found for the outcome of the injection treatment (R. 2. > 0.25). Conclusion. Factors associated with a worse outcome following a steroid injection were identified and should be considered when choosing the treatment of a trigger finger. In women with a trigger finger, the choice of treatment should take into account whether there are also one or more patient- or trigger-related factors that increase the risk of conversion to surgery.

Aims. The aims of this study were to describe the epidemiology of metacarpal shaft fractures (MSFs), assess variation in treatment and complications following standard care, document hospital resource use, and explore factors associated with treatment modality. Methods. A multicentre, cross-sectional retrospective study of MSFs at six centres in the UK. We collected and analyzed healthcare records, operative notes, and radiographs of adults presenting within ten days of a MSF affecting the second to fifth metacarpal between 1 August 2016 and 31 July 2017. Total emergency department (ED) attendances were used to estimate prevalence. Results. A total of 793 patients (75% male, 25% female) with 897 MSFs were included, comprising 0.1% of 837,212 ED attendances. The annual incidence of MSF was 40 per 100,000. The median age was 27 years (IQR 21 to 41); the highest incidence was in men aged 16 to 24 years. Transverse fractures were the most common. Over 80% of all fractures were treated non-surgically, with variation across centres. Overall, 12 types of non-surgical and six types of surgical treatment were used. Fracture pattern, complexity, displacement, and age determined choice of treatment. Patients who were treated surgically required more radiographs and longer radiological and outpatient follow-up, and were more likely to be referred for therapy. Complications occurred in 5% of patients (39/793). Most patients attended planned follow-up, with 20% (160/783) failing to attend at least one or more clinic appointments. Conclusion. MSFs are common hand injuries among young, working (economically active) men, but there is considerable heterogeneity in treatment, rehabilitation, and resource use. They are a burden on healthcare resources and society, thus further research is needed to optimize treatment. Cite this article: Bone Jt Open 2024;5(8):652–661

Aims. Complete ruptures of the ulnar collateral ligament (UCL) of the thumb are a common injury, yet little is known about their current management in the UK. The objective of this study was to assess the way complete UCL ruptures are managed in the UK. Methods. We carried out a multicentre, survey-based cross-sectional study in 37 UK centres over a 16-month period from June 2022 to September 2023. The survey results were analyzed descriptively. Results. A total of 37 centres participated, of which nine were tertiary referral hand centres and 28 were district general hospitals. There was a total of 112 respondents (69 surgeons and 43 hand therapists). The strongest influence on the decision to offer surgery was the lack of a firm ‘endpoint’ to stressing the metacarpophalangeal joint (MCPJ) in either full extension or with the MCPJ in 30° of flexion. There was variability in whether additional imaging was used in managing acute UCL injuries, with 46% routinely using additional imaging while 54% did not. The use of a bone anchor was by far the most common surgical option for reconstructing an acute ligament avulsion (97%, n = 67) with a transosseous suture used by 3% (n = 2). The most common duration of immobilization for those managed conservatively was six weeks (58%, n = 65) and four weeks (30%, n = 34). Most surgeons (87%, n = 60) and hand therapists (95%, n = 41) would consider randomizing patients with complete UCL ruptures in a future clinical trial. Conclusion. The management of complete UCL ruptures in the UK is highly variable in certain areas, and there is a willingness for clinical trials on this subject.

Aims. The benefit of MRI in the preoperative assessment of scaphoid proximal fragment vascularity remains controversial. The purpose of this study is to compare preoperative MRI findings to intraoperative bleeding of the proximal scaphoid. Methods. A retrospective review of 102 patients who underwent surgery for scaphoid nonunion between January 2000 and December 2020 at a single institution were identified. Inclusion criteria were: isolated scaphoid nonunion; preoperative MRI assessing the proximal fragment vascularity; and operative details of the vascularity of the proximal fragment with the tourniquet deflated. MRI results and intraoperative findings were dichotomized as either ‘yes’ or ‘no’ for the presence of vascularity. A four-fold contingency table was used to analyze the utility of preoperative MRI with 95% confidence intervals. Relative risk was calculated for subgroups to analyze the association between variables and MRI accuracy. Results. Preoperative MRI identified 55 proximal scaphoid fragments with ischaemia and 47 with vascularized proximal fragments. After the proximal fragment was prepared, the tourniquet was deflated and assessed for bleeding; 63 proximal fragments had no bleeding and 39 demonstrated bleeding. MRI was not reliable or accurate in the assessment of proximal fragment vascularity when compared with intraoperative assessment of bleeding. No patient or MRI factors were identified to have a statistical impact on MRI accuracy. Conclusion. Current preoperative MRI protocols and diagnostic criteria do not provide a high degree of correlation with observed intraoperative assessment of proximal fragment bleeding. While preoperative MRI may assist in surgical planning, intraoperative assessment remains the best means for assessing proximal fragment vascularity in scaphoid nonunion. Future efforts should focus on the development of objective measures of osseous blood flow that may be performed intraoperatively. Cite this article: Bone Joint J 2023;105-B(6):657–662

Aims. Wrist arthroscopy is a standard procedure in hand surgery for diagnosis and treatment of wrist injuries. Even though not generally recommended for similar procedures, general administration of perioperative antibiotic prophylaxis (PAP) is still widely used in wrist arthroscopy. Methods. A clinical ambispective dual-centre study was performed to determine whether PAP reduces postoperative infection rates after soft tissue-only wrist arthroscopies. Retrospective and prospective data was collected at two hospitals with departments specialized in hand surgery. During the study period, 464 wrist arthroscopies were performed, of these 178 soft-tissue-only interventions met the study criteria and were included. Signs of postoperative infection and possible adverse drug effects (ADEs) of PAP were monitored. Additionally, risk factors for surgical site infection (SSIs), such as diabetes mellitus and BMI, were obtained. Results. The overall infection rate of SSI was zero. Neither in the PAP group (n = 69) nor in the control group (n = 109) were signs of postoperative infection observed. Observed symptoms of ADEs were three-times higher in the PAP group when compared to the control-group (16.3 vs 5.5%; p = 0.043). No major ADEs were observed, but one in ten patients in the PAP group reported mild to severe intestinal or hypersensitivity symptoms. Conclusion. We demonstrate that the number needed to treat (NNT) with PAP to prevent one postoperative infection in soft-tissue arthroscopies of the wrist is > 109. Conversely, symptoms of ADEs were reported by one out of ten patients given PAP. Considering the high NNT to prevent postoperative infection and the large number of ADEs caused by PAP, we recommend not to use PAP routinely in soft-tissue arthroscopies of the wrist. Subsequent large-scale studies should be conducted to substantiate these results. Cite this article: Bone Jt Open 2023;4(4):219–225

Aims. A conventional arthroscopic capsuloligamentous repair is a reliable surgical solution in most patients with scapholunate instability. However, this repair does not seem to be sufficient for more advanced injuries. The aim of this study was to evaluate the functional results of a wide arthroscopic dorsal capsuloligamentous repair (WADCLR) in the management of severe scapholunate instability. Methods. This was a prospective single-centre study undertaken between March 2019 and May 2021. The primary outcome was the evaluation of the reduction of the radiological deformity and the functional outcomes after WADCLR. A secondary outcome was the evaluation of the effectiveness of this technique in patients with the most severe instability (European Wrist Arthroscopy Society (EWAS) stage 5). The patients were reviewed postoperatively at three, six, and 12 months. Results. The study included 112 patients (70 male and 42 female). Their mean age was 31.6 years (16 to 55). A total of three patients had EWAS stage 3A injuries, 12 had stage 3B injuries, 29 had stage 3C injuries, 56 had stage 4 injuries, and 12 had stage 5 injuries. There was a significant improvement of the radiological signs in all patients with a return to normal values. There was also a significant improvement in all aspects of function except for flexion, in which the mean increase was negligible (0.18° on average). There was also a significant improvement in all criteria for patients with a stage 5 injury, except for some limitation of extension, flexion, and radial and ulnar deviation, although these showed a trend towards improvement (except for flexion). Conclusion. WADCLR is a minimally invasive, easy, and reproducible technique with few complications, offering a clear improvement in function and a reduction in the radiological deformity at one year postoperatively.

Aims. The primary aim of this study was to describe long-term patient-reported outcomes after ulna shortening osteotomy for ulna impaction syndrome. Methods. Overall, 89 patients treated between July 2011 and November 2017 who had previously taken part in a routine outcome evaluation up to 12 months postoperatively were sent an additional questionnaire in February 2021. The primary outcome was the Patient-Rated Wrist and Hand Evaluation (PRWHE) total score. Secondary outcomes included patient satisfaction with treatment results, complications, and subsequent treatment for ulnar-sided wrist pain. Linear mixed models were used to compare preoperative, 12 months, and late follow-up (ranging from four to nine years) PRWHE scores. Results. Long-term outcomes were available in 66 patients (74%) after a mean follow-up of six years (SD 1). The mean PRWHE total score improved from 63 before surgery to 19 at late follow-up (difference in means (Δ) 44; 95% confidence interval (CI) 39 to 50; p = <0.001). Between 12 months and late follow-up, the PRWHE total score also improved (Δ 12; 95% CI 6 to 18; p = < 0.001). At late follow-up, 14/66 of patients (21%) reported a PRWHE total score of zero, whereas this was 3/51 patients (6%) at 12 months (p = 0.039). In all, 58/66 patients (88%) would undergo the same treatment again under similar circumstances. Subsequent treatment (total n = 66; surgical n = 57) for complications or recurrent symptoms were performed in 50/66 patients (76%). The most prevalent type of reoperation was hardware removal in 42/66 (64%), and nonunion occurred in 8/66 (12%). Conclusion. Ulna shortening osteotomy improves patient-reported pain and function that seems to sustain at late follow-up. While satisfaction levels are generally high, reoperations such as hardware removal are common. Cite this article: Bone Jt Open 2022;3(5):375–382

Aims. The aim of this study was to evaluate the need for hand trauma services during the COVID-19 pandemic lockdown, specifically related to surgical requirements. This will provide useful information for planning and resource allocation in the event of any further lockdown. Methods. A prospective analsysis of all patients attending our hand trauma unit throughout the UK COVID-19 lockdown period (24 March to 10 May 2020) was carried out. Prospectively collected departmental data from the same period in 2019 was obtained and reviewed for comparison. The number of patients attending clinic, undergoing surgery, the type of surgical procedure, and rate of surgery was compared. Results. In all, 463 patients attended hand trauma services during the lockdown period compared to 793 in 2019 (32% reduction); 190 surgical procedures were carried out during lockdown compared to 236 in 2019 (20% reduction). Intervention rate was higher during the lockdown period (41% compared to 30%). There was no difference in the type of cases. In the first half of lockdown, 47% fewer procedures were performed than in 2019, but in the second half of lockdown 13% more procedures were carried out than the same period in 2019. Conclusion. Requirements for hand trauma surgery remain high during a pandemic lockdown. Attendances and surgical requirements can be expected to steadily return to normal levels during a prolonged lockdown period. Throughout any future lockdown period adequate surgical provision must be maintained for patients with hand injuries. Cite this article: Bone Joint Open 2020;1-10:639–643

Aims

The aim of this study was to compare the cost-effectiveness of surgical fixation with Kirschner (K-)wire ersus moulded casting after manipulation of a fracture of the distal radius in an operating theatre setting.

Aims. The primary aim of this study was to assess if traumatic triangular fibrocartilage complex (TFCC) tears can be treated successfully with immobilization alone. Our secondary aims were to identify clinical factors that may predict a poor prognosis. Methods. This was a retrospective analysis of 89 wrists in 88 patients between January 2015 and January 2019. All patients were managed conservatively initially with either a short-arm or above-elbow custom-moulded thermoplastic splint for six weeks. Outcome measures recorded included a visual analogue scale for pain, Patient-Rated Wrist Evaluation, Disabilities of the Arm, Shoulder and Hand score, and the modified Mayo Wrist Score (MMWS). Patients were considered to have had a poor outcome if their final MMWS was less than 80 points, or if they required eventual surgical intervention. Univariate and logistic regression analyses were used to identify independent predictors for a poor outcome. Results. In total, 76% of wrists (42/55) treated with an above-elbow splint had a good outcome, compared to only 29% (10/34) with a short-arm splint (p < 0.001). The presence of a complete foveal TFCC tear (p = 0.009) and a dorsally subluxated distal radioulnar joint (DRUJ) (p = 0.032) were significantly associated with a poor outcome on univariate analysis. Sex, age, energy of injury, hand dominance, manual occupation, ulnar variance, and a delay in initial treatment demonstrated no significant association. Multiple logistic regression revealed that short-arm immobilization (p < 0.001) and DRUJ subluxation (p = 0.020) were significant independent predictive factors of an eventual poor outcome. Conclusion. Nonoperative management of traumatic TFCC injuries with above-elbow immobilization is a viable treatment method, particularly in patients without DRUJ subluxation. Early surgery should be considered for patients with dorsal ulnar subluxation treated with short-arm splints to prevent prolonged morbidity. Cite this article: Bone Joint J 2021;103-B(8):1386–1391

Aims

The study aimed to assess the clinical outcomes of arthroscopic debridement and partial excision in patients with traumatic central tears of the triangular fibrocartilage complex (TFCC), and to identify prognostic factors associated with unfavourable clinical outcomes.

Aims

It is not clear which type of casting provides the best initial treatment in adults with a distal radial fracture. Given that between 32% and 64% of adequately reduced fractures redisplace during immobilization in a cast, preventing redisplacement and a disabling malunion or secondary surgery is an aim of treatment. In this study, we investigated whether circumferential casting leads to fewer fracture redisplacements and better one-year outcomes compared to plaster splinting.

Aims

To estimate the potential cost-effectiveness of adalimumab compared with standard care alone for the treatment of early-stage Dupuytren’s disease (DD) and the value of further research from an NHS perspective.

Aims

The primary aim of this study was to report the radiological outcomes of patients with a dorsally displaced distal radius fracture who were randomized to a moulded cast or surgical fixation with wires following manipulation and closed reduction of their fracture. The secondary aim was to correlate radiological outcomes with patient-reported outcome measures (PROMs) in the year following injury.

Aims

The evidence demonstrating the superiority of early MRI has led to increased use of MRI in clinical pathways for acute wrist trauma. The aim of this study was to describe the radiological characteristics and the inter-observer reliability of a new MRI based classification system for scaphoid injuries in a consecutive series of patients.

Aims

There is ambiguity surrounding the degree of scaphoid union required to safely allow mobilization following scaphoid waist fracture. Premature mobilization could lead to refracture, but late mobilization may cause stiffness and delay return to normal function. This study aims to explore the risk of refracture at different stages of scaphoid waist fracture union in three common fracture patterns, using a novel finite element method.

Aims

There is no level I evidence dealing with the optimal period of immobilization for patients with a displaced distal radial fracture following closed reduction. A shorter period might lead to a better functional outcome due to less stiffness and pain. The aim of this study was to investigate whether this period could be safely reduced from six to four weeks.

Aims

Patients with midcarpal instability are difficult to manage. It is a rare condition, and few studies have reported the outcomes of surgical treatment. No prospective or retrospective study has reported the results of arthroscopic palmar capsuloligamentous suturing. Our aim was to report the results of a prospective study of arthroscopic suture of this ligament complex in patients with midcarpal instability.

Aims

To analyze the short-term outcome of two types of total wrist arthroplasty (TWA) in terms of wrist function, migration, and periprosthetic bone behaviour.
