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

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:
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. Methods. The most common anatomical variant of the scaphoid was modelled from a CT scan of a healthy hand and wrist using 3D Slicer freeware. This model was uploaded into COMSOL Multiphysics software to enable the application of physiological enhancements. Three common waist fracture patterns were produced following the Russe classification. Each fracture had differing stages of healing, ranging from 10% to 90% partial union, with increments of 10% union assessed. A physiological force of 100 N acting on the distal pole was applied, with the risk of refracture assessed using the Von Mises stress. Results. Overall, 90% to 30% fracture unions demonstrated a small, gradual increase in the Von Mises stress of all fracture patterns (16.0 MPa to 240.5 MPa). All fracture patterns showed a greater increase in Von Mises stress from 30% to 10% partial union (680.8 MPa to 6,288.6 MPa). Conclusion. Previous studies have suggested 25%, 50%, and 75% partial union as sufficient for resuming hand and wrist mobilization. This study shows that 30% union is sufficient to return to normal hand and wrist function in all three fracture patterns. Both 50% and 75% union are unnecessary and increase the risk of post-fracture stiffness. This study has also demonstrated the feasibility of finite element analysis (FEA) in scaphoid waist fracture research. FEA is a sustainable method which does not require the use of finite scaphoid cadavers, hence increasing accessibility into future scaphoid waist fracture-related research. Cite this article:

Aims. We aimed to compare reoperations following distal radial fractures (DRFs) managed with early fixation versus delayed fixation following initial closed reduction (CR). Methods. We used administrative databases in Ontario, Canada, to identify DRF patients aged 18 years or older from 2003 to 2016. We used procedural and fee codes within 30 days to determine which patients underwent early fixation (≤ seven days) or delayed fixation following CR. We grouped patients in the delayed group by their time to definitive fixation (eight to 14 days, 15 to 21 days, and 22 to 30 days). We used intervention and diagnostic codes to identify reoperations within two years. We used multivariable regression to compare the association between early versus delayed fixation and reoperation for all patients and stratified by age (18 to 60 years and > 60 years). Results. We identified 14,960 DRF patients, 8,339 (55.7%) of whom underwent early surgical fixation (mean 2.9 days (SD 1.8)). In contrast, 4,042 patients (27.0%) underwent delayed fixation between eight and 14 days (mean 10.2 days (SD 2.2)), 1,892 (12.7%) between 14 and 21 days (mean 17.5 days (SD 1.9)) and 687 (4.6%) > 21 days (mean 24.8 days (SD 2.4)) post-fracture. Patients who underwent delayed fixation > 21 days post-fracture had a higher odds of reoperation (odds ratio (OR) 1.33 (95% CI 1.11 to 1.79) vs early fixation). This worsened for patients aged > 60 years (OR 1.69 (95% CI 1.11 to 2.79)). We found no difference in the odds of reoperation for patients who underwent delayed fixation within eight to 14 or 15 to 21 days post-fracture (vs early fixation). Conclusion. These data suggest that DRF patients with fractures with unacceptable reduction following CR should be managed within three weeks to avoid detrimental outcomes. Prospective studies are required to confirm these findings. Cite this article:
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:
Aims. The aim of this study was to develop a core outcome set of what to measure in all future clinical research on hand fractures and joint injuries in adults. Methods. Phase 1 consisted of steps to identify potential outcome domains through systematic review of published studies, and exploration of the patient perspective through qualitative research, consisting of 25 semi-structured interviews and five focus groups. Phase 2 involved key stakeholder groups (patients, hand surgeons, and hand therapists) prioritizing the outcome domains via a three-round international Delphi survey, with a final consensus meeting to agree the final core outcome set. Results. The systematic review of 160 studies identified 74 outcome domains based on the World Health Organization International Classification of Functioning, Disability, and Health. Overall, 35 domains were generated through thematic analysis of the patient interviews and focus groups. The domains from these elements were synthesised to develop 37 outcome domains as the basis of the Delphi survey, with a further four generated from participant suggestions in Round 1. The Delphi survey identified 20 outcome domains as ‘very important’ for the core outcome set. At the consensus meeting, 27 participants from key stakeholder groups selected seven outcomes for the core outcome set: pain/discomfort with activity, pain/discomfort with rest, fine hand use/dexterity, self-hygiene/personal care, return to usual work/job, range of motion, and patient satisfaction with outcome/result. Conclusion. This set of core outcome domains is recommended as a minimum to be reported in all clinical research on hand fractures and joint injuries in adults. While this establishes what to measure, future work will focus on determining how best to measure these outcomes. By adopting this patient-centred core outcome set, consistency and comparability of studies will be improved, aiding meta-analysis and strengthening the evidence base for management of these common and impactful injuries.

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. Methods. This prospective single-centre study was undertaken between March 2012 and May 2022. The primary outcome was to evaluate the functional outcomes of arthroscopic palmar midcarpal suture. The study included 12 patients, eight male and four female, with a mean age of 27.5 years (19 to 42). They were reviewed at three months, six months, and one year postoperatively. Results. There was a significant improvement in flexion, extension, grip strength, abbreviated version of the Disabilities of the Arm, Shoulder and Hand questionnaire score, and pain, in all patients. After telephone contact with all patients in March 2023, at a mean follow-up of 3.85 years (2.2 to 6.25), no patient had a persistent or recurrent clunk. Conclusion. Arthroscopic suture of the midcarpal capsuloligamentous complex represents a minimally invasive, easy, and reproducible technique for the management of patients with midcarpal instbility, with a clear improvement in function outcomes and no complications.

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. Methods. Participants were recruited as part of DRAFFT2, a UK multicentre clinical trial. Participants were aged 16 years or over with a dorsally displaced distal radius fracture, and were eligible for the trial if they needed a manipulation of their fracture, as recommended by their treating surgeon. Participants were randomly allocated on a 1:1 ratio to moulded cast or Kirschner wires after manipulation of the fracture in the operating theatre. Standard posteroanterior and lateral radiographs were performed in the radiology department of participating centres at the time of the patient’s initial assessment in the emergency department and six weeks postoperatively. Intraoperative fluoroscopic images taken at the time of fracture reduction were also assessed. Results. Patients treated with surgical fixation with wires had less dorsal angulation of the radius versus those treated in a moulded cast at six weeks after manipulation of the fracture; the mean difference of -4.13° was statistically significant (95% confidence interval 5.82 to -2.45). There was no evidence of a difference in radial shortening. However, there was no correlation between these radiological measurements and PROMs at any timepoint in the 12 months post-injury. Conclusion. For patients with a dorsally displaced distal radius fracture treated with a closed manipulation, surgical fixation with wires leads to less dorsal angulation on radiographs at six weeks compared with patients treated in a moulded plaster cast alone. However, the difference in dorsal angulation was small and did not correlate with patient-reported pain and function. Cite this article:
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. 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. Methods. This multicentre randomized controlled trial (RCT) included adult patients with a displaced distal radial fracture, who were randomized to be treated with immobilization in a cast for four or six weeks following closed reduction. The primary outcome measure was the Patient-Rated Wrist Evaluation (PRWE) score after follow-up at one year. Secondary outcomes were the abbreviated version of the Disability of Arm, Shoulder and Hand (QuickDASH) score after one year, the functional outcome at six weeks, 12 weeks, and six months, range of motion (ROM), the level of pain after removal of the cast, and complications. Results. A total of 100 patients (15 male, 85 female) were randomized, with 49 being treated with four weeks of immobilization in a cast. A total of 93 completed follow-up. The mean PRWE score after one year was 6.9 (SD 8.3) in the four-week group compared with 11.6 (SD 14.3) in the six-week group. However, this difference of -4.7 (95% confidence interval -9.29 to 0.14) was not clinically relevant as the minimal clinically important difference of 11.5 was not reached. There was no significant difference in the ROM, radiological outcome, level of pain, or complications. Conclusion. In adult patients with a displaced and adequately reduced distal radial fracture, immobilization in a cast for four weeks is safe, and the results are similar to those after a period of immobilization of six weeks.

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. Methods. We identified 80 consecutive patients with acute scaphoid injuries at one centre who had presented within four weeks of injury. The radiographs and MRI scans were assessed by four observers, two radiologists, and two hand surgeons, using both pre-existing classifications and a new MRI based classification tool, the Oxford Scaphoid MRI Assessment Rating Tool (OxSMART). The OxSMART was used to categorize scaphoid injuries into three grades: contusion (grade 1); unicortical fracture (grade 2); and complete bicortical fracture (grade 3). Results. In total there were 13 grade 1 injuries, 11 grade 2 injuries, and 56 grade 3 injuries in the 80 consecutive patients. The inter-observer reliability of the OxSMART was substantial (Kappa = 0.711). The inter-observer reliability of detecting an obvious fracture was moderate for radiographs (Kappa = 0.436) and MRI (Kappa = 0.543). Only 52% (29 of 56) of the grade 3 injuries were detected on plain radiographs. There were two complications of delayed union, both of which occurred in patients with grade 3 injuries, who were promptly treated with cast immobilization. There were no complications in the patients with grade 1 and 2 injuries and the majority of these patients were treated with early mobilization as pain allowed. Conclusion. This MRI based classification tool, the OxSMART, is reliable and clinically useful in managing patients with acute scaphoid injuries. Cite this article:
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. Methods. An economic evaluation was conducted based on data collected from the Distal Radius Acute Fracture Fixation Trial 2 (DRAFFT2) multicentre randomized controlled trial in the UK. Resource use was collected at three, six, and 12 months post-randomization using trial case report forms and participant-completed questionnaires. Cost-effectiveness was reported in terms of incremental cost per quality-adjusted life year (QALY) gained from an NHS and personal social services perspective. Sensitivity analyses were conducted to examine the robustness of cost-effectiveness estimates, and decision uncertainty was handled using confidence ellipses and cost-effectiveness acceptability curves. Results. In the base case analysis, surgical fixation with K-wire was more expensive (£29.65 (95% confidence interval (CI) -94.85 to 154.15)) and generated lower QALYs (0.007 (95% CI -0.03 to 0.016)) than moulded casting, but this difference was not statistically significant. The probability of K-wire being cost-effective at a £20,000 per QALY cost-effectiveness threshold was 24%. The cost-effectiveness results remained robust in the sensitivity analyses. Conclusion. The findings suggest that surgical fixation with K-wire is unlikely to be a cost-effective alternative to a moulded cast in adults, following manipulation of a fracture of the distal radius in a theatre setting.

Aims. The sensitivity and specificity of electrodiagnostic parameters in diagnosing carpal tunnel syndrome (CTS) have been reported differently, and this study aims to address this gap. Methods. This case-control study was conducted on 57 cases with CTS and 58 controls without complaints, such as pain or paresthesia on the median nerve. The main assessed electrodiagnostic parameters were terminal latency index (TLI), residual latency (RL), median ulnar F-wave latency difference (FdifMU), and median sensory latency-ulnar motor latency difference (MSUMLD). Results. The mean age in cases and controls were 50.7 years (SD 9.9) and 47.9 years (SD 12.1), respectively. The CTS severity was mild in 20 patients (34.4%), moderate in 19 patients (32.8%), and severe in 19 patients (32.8%). The sensitivity and specificity of the electrodiagnostic parameters in diagnosing CTS were as follows: TLI 75.4% and 87.8%; RL 85.9% and 82.5%; FdifMU 87.9% and 82.9%; and MSUMLD 94.8% and 60.0%, respectively. Conclusion. Our findings indicated that electrodiagnostic parameters are significantly associated with the clinical manifestation of CTS, and are associated with high diagnostic accuracy in CTS diagnosis. However, further studies are required to highlight the role of electrodiagnostic parameters and their combination in CTS detection. Cite this article:
Aims. Dupuytren’s contracture is characterized by increased fibrosis of the palmar aponeurosis, with eventual replacement of the surrounding fatty tissue with palmar fascial fibromatosis. We hypothesized that adipocytokines produced by adipose tissue in contact with the palmar aponeurosis might promote fibrosis of the palmar aponeurosis. Methods. We compared the expression of the adipocytokines adiponectin and leptin in the adipose tissue surrounding the palmar aponeurosis of male patients with Dupuytren’s contracture, and of male patients with carpal tunnel syndrome (CTS) as the control group. We also examined the effects of adiponectin on fibrosis-related genes and proteins expressed by fibroblasts in the palmar aponeurosis of patients with Dupuytren’s contracture. Results. Adiponectin expression in the adipose tissue surrounding the palmar aponeurosis was significantly lower in patients with Dupuytren’s contracture than in those with CTS. The expression of fibrosis-related genes and proteins, such as types 1 and 3 collagen and α-smooth muscle actin, was suppressed in a concentration-dependent manner by adding AdipoRon, an adiponectin receptor agonist. The expression of fibrosis-related genes and proteins was also suppressed by AdipoRon in the in vitro model of Dupuytren’s contracture created by adding TGF-β to normal fibroblasts collected from patients with CTS. Conclusion. Fibrosis of the palmar aponeurosis in Dupuytren’s contracture in males may be associated with adiponectin expression in the adipose tissue surrounding the palmar aponeurosis. Although fibroblasts within the palmar aponeurosis are often the focus of attention when elucidating the pathogenesis of Dupuytren’s contracture, adiponectin expression in adipose tissues warrants closer attention in future research.

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:
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 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. Methods. A retrospective analysis was conducted on patients arthroscopically diagnosed with Palmer 1 A lesions who underwent arthroscopic debridement and partial excision from March 2009 to February 2021, with a minimum follow-up of 24 months. Patients were assessed using the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, Mayo Wrist Score (MWS), and visual analogue scale (VAS) for pain. The poor outcome group was defined as patients whose preoperative and last follow-up clinical score difference was less than the minimal clinically important difference of the DASH score (10.83). Baseline characteristics, arthroscopic findings, and radiological factors (ulnar variance, MRI, or arthrography) were evaluated to predict poor clinical outcomes. Results. A total of 114 patients were enrolled in this study, with a mean follow-up period of 29.8 months (SD 14.4). The mean DASH score improved from 36.5 (SD 21.5) to 16.7 (SD 14.3), the mean MWS from 59.7 (SD 17.9) to 79.3 (SD 14.3), and the mean VAS pain score improved from 5.9 (SD 1.8) to 2.2 (SD 2.0) at the last follow-up (all p < 0.001). Among the 114 patients, 16 (14%) experienced poor clinical outcomes and ten (8.8%) required secondary ulnar shortening osteotomy. Positive ulnar variance was the only factor significantly associated with poor clinical outcomes (p < 0.001). Positive ulnar variance was present in 38 patients (33%); among them, eight patients (21%) required additional operations. Conclusion. Arthroscopic debridement alone appears to be an effective and safe initial treatment for patients with traumatic central TFCC tears. The presence of positive ulnar variance was associated with poor clinical outcomes, but close observation after arthroscopic debridement is more likely to be recommended than ulnar shortening osteotomy as a primary treatment.

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. Methods. In a pragmatic, open-label, multicentre, two-period cluster-randomized superiority trial, we compared these two types of casting. Recruitment took place in ten hospitals. Eligible patients aged ≥ 18 years with a displaced distal radial fracture, which was acceptably aligned after closed reduction, were included. The primary outcome measure was the rate of redisplacement within five weeks of immobilization. Secondary outcomes were the rate of complaints relating to the cast, clinical outcomes at three months, patient-reported outcome measures (PROMs) (using the numerical rating scale (NRS), the abbreviated version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH), and Patient-Rated Wrist/Hand Evaluation (PRWHE) scores), and adverse events such as the development of compartment syndrome during one year of follow-up. We used multivariable mixed-effects logistic regression for the analysis of the primary outcome measure. Results. The study included 420 patients. There was no significant difference between the rate of redisplacement of the fracture between the groups: 47% (n = 88) for those treated with a plaster splint and 49% (n = 90) for those treated with a circumferential cast (odds ratio 1.05 (95% confidence interval (CI) 0.65 to 1.70); p = 0.854). Patients treated in a plaster splint reported significantly more pain than those treated with a circumferential cast, during the first week of treatment (estimated mean NRS 4.7 (95% CI 4.3 to 5.1) vs 4.1 (95% CI 3.7 to 4.4); p = 0.014). The rate of complaints relating to the cast, clinical outcomes and PROMs did not differ significantly between the groups (p > 0.05). Compartment syndrome did not occur. Conclusion. Circumferential casting did not result in a significantly different rate of redisplacement of the fracture compared with the use of a plaster splint. There were comparable outcomes in both groups.

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. Methods. We used data from the Repurposing anti-TNF for Dupuytren’s disease (RIDD) randomized controlled trial of intranodular adalimumab injections in patients with early-stage progressive DD. RIDD found that intranodular adalimumab injections reduced nodule hardness and size in patients with early-stage DD, indicating the potential to control disease progression. A within-trial cost-utility analysis compared four adalimumab injections with no further treatment against standard care alone, taking a 12-month time horizon and using prospective data on EuroQol five-dimension five-level questionnaire (EQ-5D-5L) and resource use from the RIDD trial. We also developed a patient-level simulation model similar to a Markov model to extrapolate trial outcomes over a lifetime using data from the RIDD trial and a literature review. This also evaluated repeated courses of adalimumab each time the nodule reactivated (every three years) in patients who initially responded. Results. The within-trial economic evaluation found that adalimumab plus standard care cost £503,410 per quality-adjusted life year (QALY) gained versus standard care alone over a 12-month time horizon. The model-based extrapolation suggested that, over a lifetime, repeated courses of adalimumab could cost £14,593 (95% confidence interval £7,534 to £42,698) per QALY gained versus standard care alone. If the NHS was willing to pay £20,000/QALY gained, there is a 77% probability that adalimumab with retreatment is the best value for money. Conclusion. Repeated courses of adalimumab are likely to be a cost-effective treatment for progressive early-stage DD. The value of perfect parameter information that would eliminate all uncertainty around the parameters estimated in RIDD and the duration of quiescence was estimated to be £105 per patient or £272 million for all 2,584,411 prevalent cases in the UK.

Aims. This study aims to report the outcomes in the treatment of unstable proximal third scaphoid nonunions with arthroscopic curettage, non-vascularized bone grafting, and percutaneous fixation. Methods. This was a retrospective analysis of 20 patients. All cases were delayed presentations (n = 15) or failed nonoperatively managed scaphoid fractures (n = 5). Surgery was performed at a mean duration of 27 months (7 to 120) following injury with arthroscopic debridement and arthroscopic iliac crest autograft. Fracture fixation was performed percutaneously with Kirschner (K)-wires in 12 wrists, a headless screw in six, and a combination of a headless screw and single K-wire in two. Clinical outcomes were assessed using grip strength, patient-reported outcome measures, and wrist range of motion (ROM) measurements. Results. Intraoperatively, established avascular necrosis of the proximal fragment was identified in ten scaphoids. All fractures united within 16 weeks, confirmed by CT. At a mean follow-up of 31 months (12 to 64), there were significant improvements in the Patient-Rated Wrist Evaluation, Mayo Wrist Score, abbreviated Disabilities of the Arm, Shoulder and Hand score, wrist ROM, grip strength, and the patients’ subjective pain score. No peri- or postoperative complications were encountered. Conclusion. Our data indicate that arthroscopic bone grafting and fixation with cancellous autograft is a viable method in the treatment of proximal third scaphoid nonunions, regardless of the vascularity of the proximal fragment.

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. To explore individuals’ experience of a scaphoid waist fracture and its subsequent treatment. Methods. A purposive sample was created, consisting of 49 participants in the Scaphoid Waist Internal Fixation for Fractures Trial of initial surgery compared with plaster cast treatment for fractures of the scaphoid waist. The majority of participants were male (35/49) and more younger participants (28/49 aged under 30 years) were included. Participants were interviewed six weeks or 52 weeks post-recruitment to the trial, or at both timepoints. Interviews were semistructured and analyzed inductively to generate cross-cutting themes that typify experience of the injury and views upon the treatment options. Results. Data show that individual circumstances might exaggerate or mitigate the limitations associated with a scaphoid fracture, and that an individual’s sense of recovery is subjective and more closely aligned with perceived functional abilities than it is with bone union. Misconceptions that surgery promises a speedier and more secure form of recovery means that some individuals, whose circumstances prescribe a need for quick return to function, express a preference for this treatment modality. Clinical consultations need to negotiate the imperfect relationship between bone union, normal function, and an individual’s sense of recovery. Enhancing patients’ perceptions of regaining function, with removable splints and encouraging home exercise, will support satisfaction with care and discourage premature risk-taking. Conclusion. Clinical decision-making in the management of scaphoid fractures should recognize that personal circumstances will influence how functional limitations are experienced. It should also recognize that function overrides a concern for bone union, and that the consequences of fractures are poorly understood. Where possible, clinicians should reinforce in individuals a sense that they are making progress in their recovery. Cite this article:
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:
Aims. The aim of this study was to describe the introduction of a virtual pathway for the management of patients with a suspected fracture of the scaphoid, and to report patient-reported outcome measures (PROMs) and satisfaction following treatment using this service. Methods. All adult patients who presented with a clinically suspected scaphoid fracture that was not visible on radiographs at the time of presentation during a one-year period were eligible for inclusion in the pathway. Demographic details, findings on examination, and routine four-view radiographs at the time of presentation were collected. All radiographs were reviewed virtually by a single consultant hand surgeon, with patient-initiated follow-up on request. PROMs were assessed at a minimum of one year after presentation and included the abbreviated version of the Disabilities of the Arm, Shoulder and Hand Score (QuickDASH), the EuroQol five-dimension five-level health questionnaire (EQ-5D-5L), the Net Promoter Score (NPS), and return to work. Results. A total of 221 patients were referred to the virtual pathway. Their mean age was 41 years (range 16 to 87) and there were 99 male patients (45%). A total of 189 patients (86%) were discharged with advice and 19 (9%) were recalled for clinical review: seven with an undisplaced scaphoid fracture, six with another fracture of the hand or wrist, two with a scapholunate ligament injury, and four in whom no abnormality was detected. A total of 13 patients (6%) initiated follow-up with the hand service: no fracture or ligament injury was identified in this group. PROMs were available for 179 patients (81%) at a mean follow-up of 19 months (range 13 to 33). The median QuickDASH score was 2.3 (interquartile range (IQR) 0 to 15.9), the median EQ-5D-5L was 0.85 (IQR 0.73 to 1.00), the NPS was 76, and 173 patients (97%) were satisfied with their treatment. There were no documented cases of symptomatic nonunion one year following injury. Conclusion. We describe the introduction of a virtual pathway for the management of patients with a suspected scaphoid fracture. We found high levels of patient satisfaction, excellent PROMs, and no detrimental effects in the vast majority of cases. Cite this article:
Aims. Osteoarthritis (OA) affecting the thumb carpometacarpal joint (CMCJ) is a common painful condition. In this study, we aimed to explore clinicians’ approach to management with a particular focus on the role of specific interventions that will inform the design of future clinical trials. Methods. We interviewed a purposive sample of 24 clinicians, consisting of 12 surgeons and 12 therapists (four occupational therapists and eight physiotherapists) who managed patients with CMCJ OA. This is a qualitative study using semi-structured, online interviews. Interviews were audio-recorded, transcribed verbatim, and analyzed using thematic analysis. Results. A total of 14 themes were developed, six of which were developed relating to the clinical management of CMCJ OA: 1) A flexible ‘ladder’ approach starting with conservative treatment first; 2) The malleable role of steroid injection; 3) Surgery as an invasive and risky last resort; 4) A shared and collaborative approach; 5) Treating the whole person; and 6) Severity of life impact influences treatment. The remaining eight themes were developed relating to clinical trial barriers and facilitators: 1) We need to embrace uncertainty; 2) You are not losing out by taking part; 3) It is difficult to be neutral about certain treatments; 4) Difficult to recruit to ‘no treatment’ ; 5) Difficult to recruit to a trial comparing no surgery to surgery; 6) Patients are keen to participate in research; 7) Burden on staff and participants; and 8) A enthusiasm for a variety of potential trial arms. Conclusion. Our findings contribute to a better understanding of how clinicians manage thumb CMCJ OA in their practice settings. Our study also provides useful insights informing the design of randomized clinical trials involving steroid injections and surgery in people with thumb CMCJ OA. Cite this article:
Aims. Studies on long-term patient-reported outcomes after open surgery for triangular fibrocartilage complex (TFCC) are scarce. Surgeons and patients would benefit from self-reported outcome data on pain, function, complications, and satisfaction after this surgery to enhance shared decision-making. The aim of this study is to determine the long-term outcome of adults who had open surgery for the TFCC. Methods. A prospective cohort study that included patients with open surgery for the TFCC between December 2011 and September 2015. In September 2020, we sent these patients an additional follow-up questionnaire, including the Patient-Rated Wrist Evaluation (PRWE), to score satisfaction, complications, pain, and function. Results. A total of 113 patients were included in the analysis. At ≥ 60 months after an open TFCC reinsertion, we found a mean PRWE total score of 19 (SD 21), a mean PRWE pain score of 11 (SD 11), and a PRWE function score of 9 (SD 10). The percentage of patients obtaining minimum clinically important difference rose from 77% at 12 months to 83% at more than 60 months (p < 0.001). Patients reported fewer complications than surgeons, and overall complication rate was low. Conclusion. Outcomes of patient-reported pain, function scores, and satisfaction are improved five years after open surgery for the TFCC. Cite this article:
Aims. The aim of this study was to assess and compare active rotation of the forearm in normal subjects after the application of a short-arm cast (SAC) in the semisupination position and a long-arm cast (LAC) in the neutral position. A clinical study was also conducted to compare the functional outcomes of using a SAC in the semisupination position with those of using a LAC in the neutral position in patients who underwent arthroscopic triangular fibrocartilage complex (TFCC) foveal repair. Methods. A total of 40 healthy right-handed volunteers were recruited. Active pronation and supination of the forearm were measured in each subject using a goniometer. In the retrospective clinical study, 40 patients who underwent arthroscopic foveal repair were included. The wrist was immobilized postoperatively using a SAC in the semisupination position (approximately 45°) in 16 patients and a LAC in 24. Clinical outcomes were assessed using grip strength and patient-reported outcomes. The degree of disability caused by cast immobilization was also evaluated when the cast was removed. Results. Supination was significantly more restricted with LACs than with SACs in the semisupination position in male and female patients (p < 0.001 for both). However, pronation was significantly more restricted with SACs in the semisupination position than with LACs in female patients (p = 0.003) and was not significantly different in male patients (p = 0.090). In the clinical study, both groups showed improvement in all parameters with significant differences in grip strength, visual analogue scale scores for pain, modified Mayo Wrist Score, the Disability of the Arm, Shoulder, and Hand (DASH) score, and the Patient-Rated Wrist Evaluation (PRWE) score. No significant postoperative differences were noted between LACs and SACs in the semisupination position. However, the disability caused by immobilization in a cast was significantly higher in patients who had a LAC on the dominant hand (p < 0.001). Conclusion. We found that a SAC in the semisupination position is as effective as a LAC in restricting pronation of the forearm. In addition, postoperative immobilization with a SAC in the semisupination position resulted in comparable pain scores and functional outcomes to immobilization with a LAC after TFCC foveal repair, with less restriction of daily activities. Therefore, we recommend that surgeons consider using a SAC in the semisupination position for postoperative immobilization following TFCC foveal repair for dorsal instability of the distal radioulnar joint.

Aims. Current National Institute for Health and Clinical Excellence (NICE) guidance advises that MRI direct from the emergency department (ED) should be considered for suspected scaphoid fractures. This study reports the current management of suspected scaphoid fractures in the UK and assesses adherence with NICE guidance. Methods. This national cross-sectional study was carried out at 87 NHS centres in the UK involving 122 EDs and 184 minor injuries units (MIUs). The primary outcome was availability of MRI imaging direct from the ED. We also report the specifics of patient management pathways for suspected scaphoid fractures in EDs, MIUs, and orthopaedic services. Overall, 62 of 87 centres (71%) had a guideline for the management of suspected scaphoid fractures. Results. A total of 11 of 87 centres (13%) had MRI directly available from the ED. Overall, 14 centres (17%) used cross-sectional imaging direct from the ED: MRI in 11 (13%), CT in three (3%), and a mixture of MRI/CT in one (1%). Four centres (6%) used cross-sectional imaging direct from the MIU: MRI in three (4%) and CT in two (2%). Of 87 centres’ orthopaedic specialist services, 74 (85%) obtained repeat radiographs, while the most common form of definitive imaging used was MRI in 55 (63%), CT in 16 (19%), mixture of MRI/CT in three (3%), and radiographs in 11 (13%). Conclusion. Only a small minority of centres currently offer MRI directly from the ED for patients with a suspected scaphoid fracture. Further research is needed to investigate the facilitators and barriers to the implementation of NICE guidance. Cite this article:
Aims. To determine the role of early MRI in the management of suspected scaphoid fractures. Methods. A total of 337 consecutive patients presenting to an emergency department (ED) following wrist trauma over a 12-month period were prospectively included in this service evaluation project. MRI was not required in 62 patients with clear diagnoses, and 17 patients were not managed as per pathway, leaving a total of 258 patients with normal scaphoid series radiographs who were then referred directly from ED for an acute wrist MRI scan. Patient demographics, clinical details, outcomes, and complications were recorded at a minimum of a year following injury. Results. The median time from injury to ED presentation was one day and the median number of positive clinical signs was two out of three (snuffbox tenderness, tubercle tenderness, pain on telescoping). Of 258 patients referred for acute MRI, 208 scans were performed as 50 patients either did not tolerate (five patients) or did not attend their scan (45 patients). MRI scans demonstrated scaphoid fracture (13%), fracture of another
Aims. The aim of the Scaphoid Waist Internal Fixation for Fractures Trial (SWIFFT) was to determine the optimal treatment for adults with a bicortical undisplaced or minimally displaced fracture of the waist of the scaphoid, comparing early surgical fixation with initial cast immobilization, with immediate fixation being offered to patients with nonunion. Methods. A cost-effectiveness analysis was conducted to assess the relative merits of these forms of treatment. The differences in costs to the healthcare system and quality-adjusted life years (QALYs) of the patients over the one-year follow-up of the trial in the two treatment arms were estimated using regression analysis. Results. Our base case analysis found that patients randomized to early surgical fixation had statistically significantly higher mean costs to the NHS of £1,295 more than for the cast immobilization arm (p < 0.001), primarily due to the cost of surgery. They also had a marginally better quality of life, over the period, of 0.0158 QALYs; however, this was not statistically significant (p = 0.379). The mean combined cost per additional QALY was £81,962, well above the accepted threshold for cost-effectiveness used in the UK and internationally. The probability of early surgery being cost-effective in this setting was only 5.6%. Conclusion. Consistent with the clinical findings of SWIFFT, these results indicate that initial cast immobilization of minimally displaced scaphoid fractures, with immediate fixation only offered to patients with nonunion, is the optimal form of treatment, resulting in comparable outcomes with less cost to the healthcare system.

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:
Aims. Patients with a triangular fibrocartilage complex (TFCC) injury report ulnar-sided wrist pain and impaired function. The surgical procedure of TFCC reinsertion aims to improve function in patients with this injury in whom conservative treatment has failed. The purpose of this study was to investigate the outcomes of open TFCC reinsertion. Methods. The study involved 274 patients who underwent open repair of the TFCC between December 2013 and December 2018. The patients completed the Patient-Rated Wrist Evaluation (PRWE) questionnaire, and scored pain and function using a visual analogue scale (VAS). Range of motion (ROM) was assessed by experienced hand therapists. Results. Clinically significant improvements were reported in pain, function, and grip strength in 220 patients (80%) three and 12 months postoperatively. Conclusion. These data will help surgeons to make decisions about the outcomes of open repair of the TFCC and to counsel patients appropriately. Level of evidence: III. Cite this article:
Aims. The purpose was to evaluate early clinical, patient-reported, and radiological outcomes of the scapholunate ligament 360° tenodesis (SL 360) technique for treatment of scapholunate (SL) instability. Methods. We studied the results of nine patients (eight males and one female with a mean age of 44.7 years (26 to 55)) who underwent the SL 360 procedure for reducible SL instability between January 2016 and June 2019, and who were identified from retrospective review of electronic medical records. Final follow-up of any kind was a mean of 33.7 months (12.0 to 51.3). Clinical, radiological, and patient-reported outcome data included visual analogue scale (VAS) for pain, Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH), Mayo Wrist Score (MWS), and Patient-Rated Wrist Examination (PRWE). Means were analyzed using paired t-test. Results. Before surgery, patients with SL instability were significantly impaired with respect to wrist flexion, extension, and grip strength (mean flexion, 51° (20° to 85°) vs 73° (45° to 90°); mean extension, 46° (15° to 70°) vs 66° (45° to 80°); mean grip strength, 25 kg (20 to 31) vs 50 kg (35 to 68) compared to the unaffected side). The mean SL gap (4.9 mm (2.3 to 7.3) vs 2.1 mm (1.6 to 2.9)) and mean SL angle (71° (59° to 105°) vs 50° (38° to 64°) were also significantly greater in the affected wrist. At final follow-up, there was mean improvement regarding clinical, radiological, and functional outcomes comparing preoperative to final postoperative values for the VAS for pain scale, QuickDASH, MWS, PRWE, and SL gap and SL angle. Conclusion. In our small series, the SL 360 procedure for reducible SL instability has favourable early clinical, patient-reported, and radiological outcomes at a mean of 33.7 months (12.0 to 51.3). The suture tape and tendon construct confers robust stability, permitting earlier mobilization without the inherent disadvantages of Kirschner wire stabilization. Cite this article:
Aims. Displaced distal radius fractures were investigated at a level 1 major trauma centre during the COVID-19 2020 lockdown due to the implementation of temporary changes in practice. The primary aim was to establish if follow-up at one week in place of the 72-hour British Orthopaedic Association Standards for Trauma & Orthopaedics (BOAST) guidance was safe following manipulation under anaesthetic. A parallel adaptation during lockdown was the non-expectation of Bier’s block. The secondary aim was to compare clinical outcomes with respect to block type. Methods. Overall, 90 patients were assessed in a cross-sectional cohort study using a mixed, retrospective-prospective approach. Consecutive sampling of 30 patients pre-lockdown (P1), 30 during lockdown (P2), and 30 during post-lockdown (P3) was applied. Type of block, operative status, follow-up, and complications were extracted. Primary endpoints were early complications (≤ one week). Secondary endpoints were later complications including malunion, delayed union or osteotomy. Results. In P1, 86.6% of patients were seen between days one to three, 26.7% in P2, and 56.7% in P3. There were no documented complications from days one to three. Operative rate was 35.5%, which did not vary significantly (p= 0.712). Primary endpoints occurred between day four to seven, and included one patient each period treated for plaster cast pain. Secondary endpoints in P1 included delayed union (one patient). During P2, this included malunion (one patient), a pressure sore (one patient) and ulnar cutaneous nerve symptoms (two patients). In P3, malunion was identified in one patient. Mean follow-up was six months (4 to 9) with union rate 96%. Change in block practice varied significantly (p =＜0.05). The risk ratio of complications using regional block (Bier’s) over haematoma block was 0.65. Conclusion. Follow-up adaptations during lockdown did not adversely affect patient outcomes. Regional anaesthesia is gold standard for manipulation of displaced distal radial fractures. Cite this article:
Aims. The objective of this systematic review was to describe trapeziectomy outcomes and complications in the context of osteoarthritis of the base of the thumb after a five-year minimum follow-up. Methods. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to guide study design, and 267 full-text articles were assessed for eligibility. After exclusion criteria application, 22 studies were included, involving 728 patients and 823 trapeziectomies. Outcomes included pre- and postoperative clinical and radiological characteristics. Complications and revisions were recorded. Results. All the studies reported good results regarding pain and range of motion at the last follow-up of 8.3 years (5 to 22); the mean satisfaction rate was 91% (84% to 100%). It was difficult to assess the impact on metacarpophalangeal joint motion in extension with contrary results. The key pinch returned to its preoperative values, whereas tip pinch showed a modest improvement (+14%), with a mild improvement found in grip strength (+25%) at the last follow-up. The mean progressive trapezial collapse was 48% (0% to 85%) and was not correlated with pain, grip strength, or satisfaction. The most represented complications were linked to tendons or nerves affected during additional procedures to stabilize the joint (11.6%; n = 56). Mechanical complications included symptomatic scapho-M1 impingement (3.1%; n = 15/580), leading to nine surgical revisions out of 581 trapeziectomies. Meta-analysis was not possible due to study heterogeneity and limited data. Conclusion. After a minimum five-year follow-up, trapeziectomy achieved high patient satisfaction and pain relief. However, strength seemed to be deteriorating with detrimental consequences, but this did not correlate with trapezial collapse. The issues related to underestimating mechanical complications and varying degrees of success should be highlighted in the information given to patients. Evidence-based analyses should help the surgeon in their decision-making. Cite this article:
Aims. The results of surgery for Dupuytren’s disease can be compromised by the potential for disease recurrence and loss of function. Selecting which patients will benefit from repeat surgery, when to operate, and what procedure to undertake requires judgement and an understanding of patient expectations and functional needs. We undertook this study to investigate patient outcomes and satisfaction following repeat limited fasciectomy for recurrent Dupuytren’s disease. Methods. We prospectively identified all patients presenting with recurrence of Dupuytren’s disease who were selected for surgical treatment with repeat limited fasciectomy surgery between January 2013 and February 2015. Patients were assessed preoperatively, and again at a minimum of five years postoperatively. We identified 43 patients who were carefully selected for repeat fasciectomy involving 54 fingers. Patients with severe or aggressive disease with extensive skin involvement were not included; in our practice, these patients are instead counselled and preferentially treated with dermofasciectomy. The primary outcome measured was change in the Michigan Hand Outcomes Questionnaire (MHQ) score. Secondary outcomes were change in finger range of motion, flexion contracture, Semmes-Weinstein monofilament (SWM) values, and overall satisfaction. Results. There was a significant improvement in MHQ scores, across all domains, with a mean overall score increase of 24 points (p < 0.001). The summed flexion contracture across the metacarpophalangeal joint (MCPJ) and the proximal interphalangeal joint (PIPJ) reduced from means of 72.0° (SD 15.9°) to 5.6° (SD 6.8°) (p < 0.001). A significant increase in maximal flexion was seen at the MCPJ (p < 0.001) but not the PIPJ (p = 0.550). The mean overall satisfaction score from the visual analogue scale was 8.9 (7.9 to 10.0). Complications were uncommon although five fingers showed reduced sensibility at final follow-up. Conclusion. Our study shows that repeat limited fasciectomy for selected patients presenting with recurrence of Dupuytren’s disease can be an effective and safe treatment resulting in excellent patient-reported outcomes and levels of satisfaction.

Aims. With novel promising therapies potentially limiting progression of Dupuytren’s disease (DD), better patient stratification is needed. We aimed to quantify DD development and progression after seven years in a population-based cohort, and to identify factors predictive of disease development or progression. Methods. All surviving participants from our previous prevalence study were invited to participate in the current prospective cohort study. Participants were examined for presence of DD and Iselin’s classification was applied. They were asked to complete comprehensive questionnaires. Disease progression was defined as advancement to a further Iselin stage or surgery. Potential predictive factors were assessed using multivariable regression analyses. Of 763 participants in our original study, 398 were available for further investigation seven years later. Results. We identified 143/398 (35.9%) participants with DD, of whom 56 (39.2%) were newly diagnosed. Overall, 20/93 (21.5%) previously affected participants had disease progression, while 6/93 (6.5%) patients showed disease regression. Disease progression occurred more often in patients who initially had advanced disease. Multivariable regression analyses revealed that both ectopic lesions and a positive family history of DD are independent predictors of disease progression. Previous hand injury predicts development of DD. Conclusion. Disease progression occurred in 21.5% of DD patients in our study. The higher the initial disease stage, the greater the proportion of participants who had disease progression at follow-up. Both ectopic lesions and a positive family history of DD predict disease progression. These patient-specific factors may be used to identify patients who might benefit from treatment that prevents progression. Cite this article:
Aims. Fixation of scaphoid nonunion with a volar locking plate and cancellous bone grafting has been shown to be a successful technique in small series. Few mid- or long-term follow-up studies have been reported. The aim of this study was to report the mid-term radiological and functional outcome of plate fixation for scaphoid nonunion. Methods. Patients with a scaphoid nonunion were prospectively enrolled and treated with open reduction using a volar approach, debridement of the nonunion, and fixation using a locking plate and cancellous bone grafting, from the ipsilateral iliac crest. Follow-up included examination, functional assessment using the patient-rated wrist/hand evaluation (PRWHE), and multiplanar reformation CT scans at three-month intervals until union was confirmed. Results. A total of 49 patients with a mean age of 31 years (16 to 74) and a mean duration of nonunion of 3.6 years (0.4 to 16) were included. Postoperatively, the nonunion healed in 47 patients (96%) as shown on CT scans. The mean time to union was 4.2 months (3 to 12). Due to impingement of the plate on the volar rim of the radius and functional limitation, the hardware was removed in 18 patients. At a median follow-up of 38 months in 34 patients, the mean active range of motion (ROM) improved significantly from 89° to 124° (SD 44°; p = 0.003). The mean grip strength improved significantly from 52% to 79% (SD 28%; p < 0.001) of the contralateral side. The mean PRWHE score improved significantly from 66 to 17 points (SD 25; p < 0.001). Conclusion. Locking plate fixation supplemented with autologous cancellous bone grafting is a successful form of treatment for scaphoid nonunion. Functional outcomes improve with the passage of time, and mid-term results are excellent with a significant improvement in ROM, grip strength, and functional outcome as measured by the PRWHE.

Aims. Brachial plexus injury (BPI) is an often devastating injury that affects patients physically and emotionally. The vast majority of the published literature is based on surgeon-graded assessment of motor outcomes, but the patient experience after BPI is not well understood. Our aim was to better understand overall life satisfaction after BPI, with the goal of identifying areas that can be addressed in future delivery of care. Methods. We conducted semi-structured interviews with 15 BPI patients after initial nerve reconstruction. The interview guide was focused on the patient’s experience after BPI, beginning with the injury itself and extending beyond surgical reconstruction. Inductive and deductive thematic analysis was used according to standard qualitative methodology to better understand overall life satisfaction after BPI, contributors to life satisfaction, and opportunities for improvement. Results. Among the 15 patients interviewed, the following themes emerged: 1) happiness and life satisfaction were noted despite limitations in physical function; 2) quality of social support influences life satisfaction during recovery from BPI; and 3) social participation and having a sense of purpose impact life satisfaction during recovery from BPI. Conclusion. How patients perceive their BPI treatment and recovery varies widely, and is not directly linked to their self-reported functional outcome. Patients with stronger social circles and activities that give them a sense of fulfillment were more likely to be satisfied with their current status. Evaluating a patient’s social network, goals, and potential supportive adaptations early in the treatment timeline through coordinated multidisciplinary care may improve overall satisfaction during recovery from BPI.

Aims. The primary aim of this study was to describe patient satisfaction and health-related quality of life (HRQoL) following corrective osteotomy for a symptomatic malunion of the distal radius. Methods. We retrospectively identified 122 adult patients from a single centre over an eight-year period who had undergone corrective osteotomy for a symptomatic malunion of the distal radius. The primary long-term outcome was the Patient-Rated Wrist Evaluation (PRWE) score. Secondary outcomes included the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) score, the EQ-5D-5L score, complications, and the Net Promoter Score (NPS). Multivariate regression analysis was used to determine factors associated with the PRWE score. Results. Long-term outcomes were available for 89 patients (72%). The mean age was 57 years (SD 15) and 68 were female (76%). The median time from injury to corrective osteotomy was nine months (interquartile range (IQR) 6 to 13). At a mean follow-up of six years (1 to 11) the median PRWE score was 22 (IQR 7 to 40), the median QuickDASH score was 11.4 (IQR 2.3 to 31.8), and the median EQ-5D-5L score was 0.84 (IQR 0.69 to 1). The NPS was 69. Multivariate regression analysis showed that the presence of an associated ulnar styloid fracture was the only significant independent factor associated with a worse PRWE score when adjusting for confounding variables (p = 0.004). Conclusion. We found that corrective osteotomy for malunion of the distal radius can result in good functional outcomes and high levels of patient satisfaction. However, the presence of an ulnar styloid fracture may adversely affect function. Level of Evidence: III (cohort study). Cite this article:
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:
Aims. To assess the proportion of patients with distal radius fractures (DRFs) who were managed nonoperatively during the COVID-19 pandemic in accordance with the British Orthopaedic Association BOAST COVID-19 guidelines, who would have otherwise been considered for an operative intervention. Methods. We retrospectively reviewed the radiographs and clinical notes of all patients with DRFs managed nonoperatively, following the publication of the BOAST COVID-19 guidelines on the management of urgent trauma between 26 March and 18 May 2020. Radiological parameters including radial height, radial inclination, intra-articular step-off, and volar tilt from post-reduction or post-application of cast radiographs were measured. The assumption was that if one radiological parameter exceeds the acceptable criteria, the patient would have been considered for an operative intervention in pre-COVID times. Results. Overall, 92 patients formed the cohort of this study with a mean age of 66 years (21 to 96); 84% (n = 77) were female and 16% (n = 15) were male. In total, 54% (n = 50) of patients met at least one radiological indication for operative intervention with a mean age of 68 years (21 to 96). Of these, 42% (n = 21) were aged < 65 years and 58% (29) were aged ≥ 65 years. Conclusion. More than half of all DRFs managed nonoperatively during the COVID-19 pandemic had at least one radiological indication to be considered for operative management pre-COVID. We anticipate a proportion of these cases will require corrective surgery in the future, which increases the load on corrective upper limb elective services. This should be accounted for when planning an exit strategy and the restart of elective surgery services. Cite this article:
Aims. The aim of this study was to analyze the association between the shape of the distal radius sigmoid notch and triangular fibrocartilage complex (TFCC) foveal tear. Methods. Between 2013 and 2018, patients were retrospectively recruited in two different groups. The patient group comprised individuals who underwent arthroscopic transosseous TFCC foveal repair for foveal tear of the wrist. The control group comprised individuals presenting with various diseases around wrist not affecting the TFCC. The study recruited 176 patients (58 patients, 118 controls). The sigmoid notch shape was classified into four types (flat-face, C-, S-, and ski-slope types) and three radiological parameters related to the sigmoid notch (namely, the radius curvature, depth, and version angle) were measured. The association of radiological parameters and sigmoid notch types with the TFCC foveal tear was investigated in univariate and multivariate analyses. Receiver operating characteristic curves were used to estimate a cut-off for any statistically significant variables. Results. Univariate analysis showed that the flat-face type was more prevalent in the patients than in the control group (43% vs 21%; p = 0.002), while the C-type was lower in the patients than in the control group (3% vs 17%; p = 0.011). The depth and version angle of sigmoid notch showed a negative association with the TFCC foveal tear in the multivariate analysis (depth: odds ratio (OR) 0.380; p = 0.037; version angle: OR 0.896; p = 0.033). Estimated cut-off values were 1.34 mm for the depth (area under the curve (AUC) = 0.725) and 10.45° for the version angle (AUC = 0.726). Conclusion. The proportion of flat-face sigmoid notch type was greater in the patient group than in the control group. The depth and version angle of sigmoid notch were negatively associated with TFCC foveal injury. Cite this article:
Aims. In the UK, fasciectomy for Dupuytren’s contracture is generally performed under general or regional anaesthetic, with an arm tourniquet and in a hospital setting. We have changed our practice to use local anaesthetic with adrenaline, no arm tourniquet, and perform the surgery in a community setting. We present the outcome of a consecutive series of 30 patients. Methods. Prospective data were collected for 30 patients undergoing open fasciectomy on 36 digits (six having two digits affected), over a one-year period and under the care of two surgeons. In total, 10 ml to 20 ml volume of 1% lidocaine with 1:100,000 adrenaline was used. A standard postoperative rehabilitation regime was used. Preoperative health scores, goniometer measurements of metacarpophalangeal (MCP), proximal interphalangeal (PIP) contractures, and Unité Rheumatologique des Affections de la Main (URAM) scores were measured pre- and postoperatively at six and 12 weeks. Results. The mean preoperative contractures were 35.3° (0° to 90°) at the metacarpophalangeal joint (MCPJ), 32.5° (0° to 90°) at proximal interphalangeal joint (PIPJ) (a combined deformity of 67.8°). The mean correction was 33.6° (0° to 90°) for the MCPJ and 18.2° (0° to 70°) for the PIPJ leading to a combined correction of 51.8°. There was a complete deformity correction in 21 fingers (59.5%) and partial correction in 14 digits (37.8%) with no correction in one finger. The mean residual deformities for the partial/uncorrected group were MCP 4.2° (0° to 30°), and PIP 26.1° (0° to 85°). For those achieving a full correction the mean preoperative contracture was less particularly at the PIP joint (15.45° (0° to 60°) vs 55.33° (0° to 90°)). Mean preoperative URAM scores were higher in the fully corrected group (17.4 (4 to 31) vs 14.0 (0 to 28)), but lower at three months post-surgery (0.5 (0 to 3) vs 4.40 (0 to 18)), with both groups showing improvements. Infections occurred in two patients (three digits) and both were successfully treated with oral antibiotics. No other complications were noted. The estimated cost of a fasciectomy under local anaesthetic in the community was £184.82 per patient. The estimated hospital theatre costs for a fasciectomy was £1,146.62 under general anaesthetic (GA), and £1,085.30 under an axillary block. Conclusion. This study suggests that a fasciectomy performed under local anaesthetic with adrenaline and without an arm tourniquet and in a community setting is safe, and results in favourable outcomes regarding the degree of correction of contracture achieved, functional scores, and short-term complications. Local anaesthetic fasciectomy in a community setting achieves a saving of £961.80 for a GA and £900.48 for an axillary block per case. Cite this article:
Aims. Besides conventional radiographs, the use of MRI, CT, and bone scintigraphy is frequent in the diagnosis of a fracture of the scaphoid. However, which techniques give the best results remain unknown. The investigation of a new imaging technique initially requires an analysis of its precision. The primary aim of this study was to investigate the interobserver agreement of high-resolution peripheral quantitative CT (HR-pQCT) in the diagnosis of a scaphoid fracture. A secondary aim was to investigate the interobserver agreement for the presence of other fractures and for the classification of scaphoid fracture. Methods. Two radiologists and two orthopaedic trauma surgeons evaluated HR-pQCT scans of 31 patients with a clinically-suspected scaphoid fracture. The observers were asked to determine the presence of a scaphoid or other fracture and to classify the scaphoid fracture based on the Herbert classification system. Fleiss kappa statistics were used to calculate the interobserver agreement for the diagnosis of a fracture. Intraclass correlation coefficients (ICCs) were used to assess the agreement for the classification of scaphoid fracture. Results. A total of nine (29%) scaphoid fractures and 12 (39%) other fractures were diagnosed in 20 patients (65%) using HR-pQCT across the four observers. The interobserver agreement was 91% for the identification of a scaphoid fracture (95% confidence interval (CI) 0.76 to 1.00) and 80% for other fractures (95% CI 0.72 to 0.87). The mean ICC for the classification of a scaphoid fracture in the seven patients diagnosed with scaphoid fracture by all four observers was 73% (95% CI 0.42 to 0.94). Conclusion. We conclude that the diagnosis of scaphoid and other fractures is reliable when using HR-pQCT in patients with a clinically-suspected fracture. Cite this article:
Aims. The aim of this study was to investigate whether intraoperative 3D fluoroscopic imaging outperforms dorsal tangential views in the detection of dorsal cortex screw penetration after volar plating of an intra-articular distal radial fracture, as identified on postoperative CT imaging. Methods. A total of 165 prospectively enrolled patients who underwent volar plating for an intra-articular distal radial fracture were retrospectively evaluated to study three intraoperative imaging protocols: 1) standard 2D fluoroscopic imaging with anteroposterior (AP) and elevated lateral images (n = 55); 2) 2D fluoroscopic imaging with AP, lateral, and dorsal tangential views images (n = 50); and 3) 3D fluoroscopy (n = 60). Multiplanar reconstructions of postoperative CT scans served as the reference standard. Results. In order to detect dorsal screw penetration, the sensitivity of dorsal tangential views was 39% with a negative predictive value (NPV) of 91% and an accuracy of 91%; compared with a sensitivity of 25% for 3D fluoroscopy with a NPV of 93% and an accuracy of 93%. On the postoperative CT scans, we found penetrating screws in: 1) 40% of patients in the 2D fluoroscopy group; 2) in 32% of those in the 2D fluoroscopy group with AP, lateral, and dorsal tangential views; and 3) in 25% of patients in the 3D fluoroscopy group. In all three groups, the second compartment was prone to penetration, while the postoperative incidence decreased when more advanced imaging was used. There were no penetrating screws in the third compartment (extensor pollicis longus groove) in the 3D fluoroscopy groups, and one in the dorsal tangential views group. Conclusion. Advanced intraoperative imaging helps to identify screws which have penetrated the dorsal compartments of the wrist. However, based on diagnostic performance characteristics, one cannot conclude that 3D fluoroscopy outperforms dorsal tangential views when used for this purpose. Dorsal tangential views are sufficiently accurate to detect dorsal screw penetration, and arguably more efficacious than 3D fluoroscopy. Cite this article:
Aims. We hypothesized that the wide-awake local anaesthesia with no tourniquet (WALANT) technique is cost-effective, easy to use, safe, and reproducible, with a low learning curve towards mastery, having a high patient satisfaction rate. Furthermore, WALANT would be a suitable alternative for the austere and developing nation environments where lack of funds and resources are a common issue. Methods. This was a randomized control trial of 169 patients who required surgery for closed isolated distal radius fractures. The study was performed between March 2016 and April 2019 at a public sector level 1 trauma centre. General anaesthesia was used in 56 patients, Bier’s block in 58 patients, and WALANT in 55 patients. Data were collected on pre-, peri-, and postoperative parameters, clinical outcome, hospital costs, and patient satisfaction. One-way analysis of variance (ANOVA) was used with a p-value of 0.05 being significant. Results. Operations with WALANT proceeded sooner, and patients recovered faster, resulting in mean fewer missed working days (7.8 (SD 1.67)) compared with general anaesthesia (20.1 (SD 7.37)) or Bier’s block (14.1 (SD 7.65)) (p < 0.001). The WALANT patients did not develop complications, while the other patients did (p < 0.04). Clinical outcomes did not differ, nor did surgeon qualification affect clinical outcomes. Mean hospital costs were lower for WALANT ($428.50 (SD 77.71)) than for general anaesthesia ($630.63 (SD 114.77)) or Bier’s block ($734.00 (SD 37.54)) (p < 0.001). Patient satisfaction was also higher (p < 0.001). Conclusion. WALANT for distal radius fractures results in a faster recovery, is more cost-effective, has similar clinical outcomes, and has fewer complications than general anaesthesia or Bier's block. This makes WALANT an attractive technique in any setting, but especially in middle- and low-income countries. Cite this article:
Aims. Carpal malalignment after a distal radial fracture occurs due to loss of volar tilt. Several studies have shown that this has an adverse influence on function. We aimed to investigate the magnitude of dorsal tilt that leads to carpal malalignment, whether reduction of dorsal tilt will correct carpal malalignment, and which measure of carpal malalignment is the most useful. Methods. Radiographs of patients with a distal radial fracture were prospectively collected and reviewed. Measurements of carpal malalignment were recorded on the initial radiograph, the radiograph following reduction of the fracture, and after a further interval. Linear regression modelling was used to assess the relationship between dorsal tilt and carpal malalignment. Receiver operating characteristic (ROC) analysis was used to identify which values of dorsal tilt led to carpal malalignment. Results. A total of 250 consecutive patients with 252 distal radial fractures were identified. All measures of carpal alignment were significantly associated with dorsal tilt at each timepoint. This relationship persisted after adjustment for age, sex, and the position of the wrist. Capitate shift consistently had the strongest relationship with dorsal tilt and was the only parameter that was not influenced by age or the position of the wrist. ROC curve analysis identified that abnormal capitate shift was seen with > 9° of dorsal tilt. Conclusion. Carpal malalignment is related to dorsal tilt following a distal radial fracture. Reducing the fracture and improving dorsal tilt will reduce carpal malalignment. Capitate shift is easy to assess visually, unrelated to age and sex, and appears to be the most useful measure of carpal malalignment. The aim during reduction of a distal radial fracture should be to realign the capitate with the axis of the radius and prevent carpal malalignment. Cite this article:
Aims. The aim of this study was to compare patient-reported outcome measures (PROMs) and the Single Assessment Numerical Evaluation (SANE) score in patients treated with a volar locking plate for a distal radial fracture. Methods. This study was a retrospective review of a prospective database of 155 patients who underwent internal fixation with a volar locking plate for a distal radial fracture between August 2014 and April 2017. Data which were collected included postoperative PROMs (Disabilities of the Arm, Shoulder, and Hand questionnaire (DASH) and Patient-Rated Wrist Evaluation (PRWE)), and SANE scores at one month (n = 153), two months (n = 155), three months (n = 144), six months (n = 128), and one year (n = 73) after operation. Patients with incomplete data were excluded from this study. Correlation and agreement between PROMs and SANE scores were evaluated. Subgroup analyses were carried out to identify correlations according to variables such as age, the length of follow-up, and subcategories of the PRWE score. Results. The Pearson correlation coefficient (r) between PROMs and SANE scores was -0.76 (p < 0.001) for DASH and -0.72 (p < 0.001) for PRWE, respectively. Limits of agreement between PROMs and ‘100-SANE’ scores were met for at least 93% of the data points. In subgroup analysis, there were significant negative correlations between PROMs and SANE scores for all age groups and for follow-up of more than six months. The correlation coefficient between PRWE subcategories and SANE score was -0.67 (p < 0.001) for PRWE pain score and -0.69 (p < 0.001) for PRWE function score, respectively. Conclusion. We found a significant correlation between postoperative SANE and PROMs in patients treated with a volar locking plate for a distal radial fracture. The SANE score is thus a reliable indicator of outcome for patients who undergo surgical treatment for a radial fracture. Cite this article:
Aims. Base of thumb osteoarthritis (BTOA) is a common age-related disease which has a significant negative impact upon quality of life. Our aim was to assess current UK practice in secondary care with regard to the nature of non-surgical treatments, the surgical procedures most commonly performed, and factors influencing the surgical decision-making process. Methods. Ten consecutive patients undergoing surgery for BTOA between March 2017 and May 2019 were prospectively identified in 15 UK centres. Demographic details, duration of symptoms, radiological grade, non-surgical management strategies, and surgery conducted were recorded. A supplementary consultant questionnaire consisting of four multiple-choice-questions (MCQ) based on hypothetical clinical scenarios was distributed. Results. A total of 150 patients were identified with a mean age of 64 years (SD 9), comprising 119 females and 31 males. Median duration of symptoms prior to surgery was 24 months (Interquartile range (IQR) 12 to 40). Hand therapy was used in 67 patients (45%), splints in 80 (53%), and 121 patients (81%) received one or more intra-articular injections, of which 81 (67%) were image-guided (14 (12%) ultrasound and 67 (55%) fluoroscopic). Only 48 patients (32%) received all three non-surgical treatments. Simple trapeziectomy (79 patients) and trapeziectomy with ligament reconstruction and/or tendon interposition (69 patients) were the most commonly performed operations. One patient was treated with arthrodesis, and one with arthroplasty. The supplementary questionnaire revealed that no specific patient or disease characteristics significantly influenced the type of surgery undertaken. Conclusion. We found considerable variation in practice of both non-surgical and surgical management of BTOA. The proportion of patients exhausting non-surgical strategies before being offered surgery is low. Surgeons tend to favour a single type of surgery irrespective of patient or disease characteristics. Cite this article:
Aims. The aim of this study was to investigate whether clinical and radiological outcomes after intramedullary nailing of displaced fractures of the fifth metacarpal neck using a single thick Kirschner wire (K-wire) are noninferior to those of technically more demanding fixation with two thinner dual wires. Patients and Methods. This was a multicentre, parallel group, randomized controlled noninferiority trial conducted at 12 tertiary trauma centres in Germany. A total of 290 patients with acute displaced fractures of the fifth metacarpal neck were randomized to either intramedullary single-wire (n = 146) or dual-wire fixation (n = 144). The primary outcome was the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire six months after surgery, with a third of the minimal clinically important difference (MCID) used as the noninferiority threshold. Secondary outcomes were pain, health-related quality of life (EuroQol five-dimensional questionnaire (EQ-5D)), radiological measures, functional deficits, and complications. Results. Overall, 151/290 of patients (52%) completed the six months of follow-up, leaving 83 patients in the single-wire group and 68 patients in the dual-wire group. In the modified intention-to-treat analysis set, mean DASH scores six months after surgery were 3.8 (. sd. 7.0) and 4.4 (. sd. 9.4), respectively. With multiple imputation (n = 288), mean DASH scores were estimated at 6.3 (. sd. 8.7) and 7.0 (. sd. 10.0). Upper (1 - 2α)) confidence limits consistently remained below the noninferiority margin of 3.0 points in the DASH instrument. While there was a statistically nonsignificant trend towards a higher rate of shortening and rotational malalignment in the single wire group, no statistically significant differences were observed across groups in any secondary outcome measure. Conclusion. A single thick K-wire is sufficient for intramedullary fixation of acute displaced subcapital fractures of the fifth metacarpal neck. The less technically demanding single-wire technique produces noninferior clinical and radiological outcomes compared with the dual-wire approach. Cite this article:
Aims. The aim of this study was to investigate the difference in functional outcome after repair and non-repair of the pronator quadratus muscle in patients undergoing surgical treatment for a distal radial fracture with volar plating. Patients and Methods. A total of 72 patients with a distal radial fracture were included in this randomized clinical trial. They were allocated to have the pronator quadratus muscle repaired or not, after volar locked plating of a distal radial fracture. The patients, the assessor, the primary investigator, and the statistician were blinded to the allocation. Randomization was irreversibly performed using a web application that guaranteed a secure and tamper-free assignment. The primary outcome measure was the Patient Rated Wrist Evaluation (PRWE) after 12 months. Secondary outcomes included the Disabilities of the Arm, Shoulder and Hand (DASH) score, pronation strength, grip strength, the range of pronation and supination, complications, and the operating time. Results. Of the 72 patients, 63 (87.5%) completed follow-up for the primary outcome measure: 31 (86.1%) from the non-repair group and 32 (88.9%) from the repair group. At the 12-month follow-up, the mean difference in PRWE of 5.47 (95% confidence interval (CI) -4.02 to 14.96) between the repair (mean 18.38 (95% CI 10.34 to 26.41)) and non-repair group (mean 12.90 (95% CI 7.55 to 18.25)) was not statistically significant (p = 0.253). There was a statistically significant difference between pronation strength, favouring non-repair. We found no difference in the other secondary outcomes. Conclusion. We found that repairing pronator quadratus made no difference to the clinical outcome, 12 months after volar plating of a distal radial fracture. We conclude that there is no functional advantage in repairing this muscle under these circumstances and advise against it. Cite this article:
Aims. Plate and screw fixation has been the standard treatment for painful conditions of the wrist in non-rheumatoid patients in recent decades. We investigated the complications, re-operations, and final outcome in a consecutive series of patients who underwent wrist arthrodesis for non-inflammatory arthritis. Patients and Methods. A total of 76 patients, including 53 men and 23 women, with a mean age of 50 years (21 to 79) underwent wrist arthrodesis. Complications and re-operations were recorded. At a mean follow-up of 11 years (2 to 18), 63 patients completed questionnaires, and 57 attended for clinical and radiological assessment. Results. Of the 76 patients, 46 (60.5%) had complications, resulting in 65 re-operations, mainly related to the plate and screws. In the 63 patients who completed the questionnaires, the mean Quick Disabilities of Arm, Shoulder and Hand (QuickDASH) score was 36 (0 to 91), the mean Patient-Rated Wrist and Hand Evaluation (PRWHE) score was 40 (0 to 96), and 14 patients (22%) reported no wrist pain. Grip strength, pinch strength, and pronation and supination were significantly reduced compared with the contralateral forearm. The outcome was worse in patients who had previously undergone surgery to the wrist, and those with complications. A total of 13 are awaiting further re-operations, giving a total re-operation rate of 63% (40/63). Conclusion. We observed complications and re-operations throughout the follow-up period and therefore consider wrist arthrodesis to be more complicated than previously assumed. Many of the patients never got used to or accepted their stiff wrists and reported a substantial reduction in function and residual pain. Motion-sparing surgery should be offered prior to wrist arthrodesis. Cite this article:
Aims. The aim of the Scaphoid Magnetic Resonance Imaging in Trauma (SMaRT) trial was to evaluate the clinical and cost implications of using immediate MRI in the acute management of patients with a suspected fracture of the scaphoid with negative radiographs. Patients and Methods. Patients who presented to the emergency department (ED) with a suspected fracture of the scaphoid and negative radiographs were randomized to a control group, who did not undergo further imaging in the ED, or an intervention group, who had an MRI of the wrist as an additional test during the initial ED attendance. Most participants were male (52% control, 61% intervention), with a mean age of 36.2 years (18 to 73) in the control group and 38.2 years (20 to 71) in the intervention group. The primary outcome was total cost impact at three months post-recruitment. Secondary outcomes included total costs at six months, the assessment of clinical findings, diagnostic accuracy, and the participants’ self-reported level of satisfaction. Differences in cost were estimated using generalized linear models with gamma errors. Results. The mean cost up to three months post-recruitment per participant was £542.40 (. sd. £855.20, n = 65) for the control group and £368.40 (. sd. £338.60, n = 67) for the intervention group, leading to an estimated cost difference of £174 (95% confidence interval (CI) -£30 to £378; p = 0.094). The cost difference per participant increased to £266 (95% CI £3.30 to £528; p = 0.047) at six months. Overall, 6.2% of participants (4/65, control group) and 10.4% of participants (7/67, intervention group) had sustained a fracture of the scaphoid (p = 0.37). In addition, 7.7% of participants (5/65, control group) and 22.4% of participants (15/67, intervention group) had other fractures diagnosed (p = 0.019). The use of MRI was associated with higher diagnostic accuracy both in the diagnosis of a fracture of the scaphoid (100.0% vs 93.8%) and of any other fracture (98.5% vs 84.6%). Conclusion. The use of immediate MRI in the management of participants with a suspected fracture of the scaphoid and negative radiographs led to cost savings while improving the pathway’s diagnostic accuracy and patient satisfaction.

Aims. The aim of this study was to compare the clinical effectiveness of Kirschner wire (K-wire) fixation with locking-plate fixation for patients with a dorsally displaced fracture of the distal radius in the five years after injury. Patients and Methods. We report the five-year follow-up of a multicentre, two-arm, parallel-group randomized controlled trial. A total of 461 adults with a dorsally displaced fracture of the distal radius within 3 cm of the radiocarpal joint that required surgical fixation were recruited from 18 trauma centres in the United Kingdom. Patients were excluded if the surface of the wrist joint was so badly displaced it required open reduction. In all, 448 patients were randomized to receive either K-wire fixation or locking-plate fixation. In the K-wire group, there were 179 female and 38 male patients with a mean age of 59.1 years (19 to 89). In the locking-plate group, there were 194 female and 37 male patients with a mean age of 58.3 years (20 to 89). The primary outcome measure was the patient-rated wrist evaluation (PRWE). Secondary outcomes were health-related quality of life using the EuroQol five-dimension three-level (EQ-5D-3L) assessment, and further surgery related to the index fracture. Results. At 12 months, 402/448 participants (90%) recruited into the main study provided PRWE scores. At year two, 294 participants (66%) provided scores; at year five, 198 participants (44%) provided scores. There was no clinically relevant difference in the PRWE at any point during the five-year follow-up; at five years, the PRWE score was 8.3 (12.5) in the wire group and 11.3 (15.6) in the plate group (95% confidence interval -6.99 to 0.99; p = 0.139). Nor was there a clinically relevant difference in health-related quality of life. Only three participants had further surgery in the five years after their injury (one in the wire group and two in the plate group). Conclusion. This follow-up study continues to show no evidence of a difference in wrist pain, wrist function, or quality of life for patients treated with wires versus locking plates in the five years following a dorsally displaced fracture of the distal radius.

Aims. The aims of this study were: firstly, to investigate the influence
of the thickness of cartilage at the sigmoid notch on the inclination
of the distal radioulnar joint (DRUJ), and secondly, to compare
the sensitivity and specificity of MRI with plain radiographs for
the assessment of the inclination of the articular surface of the
DRUJ in the coronal plane. . Patients and Methods. Contemporaneous MRI images and radiographs of 100 wrists from
98 asymptomatic patients (mean age 43 years, (16 to 67); 52 male,
53%) with no history of a fracture involving the wrist or surgery
to the wrist, were reviewed. The thickness of the cartilage at the
sigmoid notch, inclination of the DRUJ and Tolat Type of each DRUJ
were determined. . Results. The assessment using MRI scans and cortical
Aims. The aims of this study were to compare the mid-term outcomes
of patients with late-stage arthritis of the wrist treated with
proximal row carpectomy (PRC) and dorsal capsular interposition
(DCI) arthroplasty with a matched cohort treated with routine PRC
alone. Patients and Methods. A total of 25 arthritic wrists (24 patients) with pre-existing
degenerative changes of the proximal capitate and/or the lunate
fossa of the radius were treated with PRC + DCI over a ten-year
period. This group of patients were matched 1:2 with a group of
50 wrists (48 patients) without degenerative changes in the capitate
or lunate fossa that were treated with a routine PRC alone during
the same period. The mean age of the patients at the time of surgery
was 56.8 years (25 to 81), and the demographics and baseline range
of movement of the wrist, grip strength, Quick Disabilities of the
Arm, Shoulder, and Hand (QuickDASH) score, and Patient-Rated Wrist
Evaluation (PRWE) score were similar in both groups. . Results. At a mean follow-up of 5.9 years (1.8 to 11.8), significant improvements
in mean grip strength, the flexion-extension arc of movement of
the wrist, QuickDASH, and PRWE scores were seen in both groups.
There was no diifference between the groups for any of the outcomes.
One patient in the PRC + DCI group required additional surgery for
a deep infection, while two in the PRC group had complications (one
wound dehiscence requiring revision closure, one transient radial
sensory neuritis). One patient in each group required total arthrodesis
of the wrist for progressive degenerative radiocarpal changes. A
total of 70 patients (93%) were satisfied with the outcomes. Conclusion. PRC with DCI is an effective form of treatment for late-stage
arthritis of the wrist involving the capitolunate joint, with mid-term
outcomes that are similar to those in patients without degenerative
changes affecting the capitate or lunate fossa who are treated with
a routine PRC alone. Cite this article:
Aims. Positive ulnar variance is an established risk factor for idiopathic
ulnar impaction syndrome (UIS). However, not all patients with positive
ulnar variance develop symptomatic UIS and other factors, including
the morphology of the lunate, may be involved. The aim of this study
was to clarify the relationship between lunate morphology and idiopathic
UIS. Patients and Methods. A cohort of 95 patients with idiopathic UIS (UIS group) was compared
with 95 asymptomatic controls with positive ulnar variance. The
shape of the lunate was measured using the capitate-triquetrum distance
(CTD), ulnar coverage ratio (UCR), radiolunate distance and radiolunate
angle. The association of radiographic parameters and lunate types
with the development of UIS was investigated in univariable and
multivariable analyses. Receiver operating characteristic curves
were used to estimate a cutoff for any statistically significant
variables. Results. The proportion of type II lunates, which have a medial hamate
facet, were significantly higher in the UIS group than in the control
group in the univariable analysis (p = 0.001). CTD (odds ratio (OR)
1.52; 95% confidence interval (CI) 1.11 to 2.06; p = 0.008) and
UCR (OR 44.78; 95% CI 5.35 to 374.90; p = 0.002) showed a positive
association with UIS in the multivariable analysis. Estimated cutoff
values were 2.5 mm for the CTD (area under the curve (AUC) = 0.65) and
0.4 for the UCR (AUC = 0.64). Conclusion. The proportion of type II lunates was greater in the UIS group
than in the control group. A large UCR, which represents the broad
base of the lunate, was positively associated with the development
of idiopathic UIS. Cite this article:
Aims. The aim of this study was to test the null hypothesis that there
is no difference, from the payer perspective, in the cost of treatment
of a distal radial fracture in an elderly patient, aged >
65 years,
between open reduction and internal fixation (ORIF) and closed reduction (CR). Materials and Methods. Data relating to the treatment of these injuries in the elderly
between January 2007 and December 2015 were extracted using the
Humana and Medicare Advantage Databases. The primary outcome of
interest was the cost associated with treatment. Secondary analysis included
the cost of common complications. Statistical analysis was performed
using a non-parametric t-test and chi-squared test. Results. Our search yielded 8924 patients treated with ORIF and 5629 patients
treated with CR. The mean cost of an uncomplicated ORIF was more
than a CR ($7749 versus $2161). The mean additional
cost of a complication in the ORIF group was greater than in the
CR group ($1853 versus $1362). Conclusion. These findings show that there are greater payer fees associated
with ORIF than CR in patients aged >
65 years with a distal radial
fracture. CR may be a higher-value intervention in these patients. Cite this article:
Aims. The aim of this meta-analysis was to assess the safety and efficacy
of collagenase clostridium histolyticum compared with fasciectomy
and percutaneous needle fasciotomy (PNF) for Dupuytren’s disease. Materials and Methods. We systematically searched PubMed, EMBASE, LILACS, Web of Science,
Cochrane, Teseo and the ClinicalTrials.gov registry for clinical
trials and cohort or case-control studies which compared the clinical
outcomes and adverse effects of collagenase with those of fasciectomy
or PNF. Of 1345 articles retrieved, ten were selected. They described
the outcomes of 425 patients treated with collagenase and 418 treated
by fasciectomy or PNF. Complications were assessed using inverse-variance
weighted odds ratios (ORs). Clinical efficacy was assessed by differences
between the means for movement of the joint before and after treatment.
Dose adjustment was applied in all cases. Results. Random-effects modelling showed that patients treated with collagenase
had 3.24 increased odds of adverse effects compared with those treated
by fasciectomy (OR 4.39) or PNF (OR 1.72,). The effect was lost
when only major complications were assessed. Joint movement analysis
revealed a difference between means of less than 10%, indicating
equivalent clinical efficacy in the short and medium term for collagenase
and fasciectomy. We were unable to analyse this for PNF due to a
shortage of data. Conclusion. There were no significant differences in effect size between
collagenase and fasciectomy. The use of collagenase was associated
with a higher overall risk of adverse effects than both fasciectomy
and PNF. Cite this article:

Australian Rules Football players after fixation of a non-thumb
metacarpal fracture was safe and effective. Patients and Methods. A total of 16 patients with a mean age of 25 years (19 to 30)
identified as having a non-thumb metacarpal fracture underwent open
reduction and internal plate and screw fixation. We compared the
players’ professional performance statistics before and after the
injury to determine whether there was any deterioration in their
post-operative performance. Results. Of the 16, 12 sustained their fracture during the season: their
mean time to return to unrestricted professional play was two weeks
(1 to 5). All except two of the 48 player performance variables
showed no reduction in performance post-operatively. Conclusion. Our data suggest that professional athletes who sustained a non-thumb
metacarpal fracture can safely return to professional play without
restriction two weeks after internal fixation. Cite this article:

Aims. Few studies have examined the long-term outcome of carpal tunnel
release (CTR). The aim of this study was to evaluate the patient-reported
long-term outcome of CTR for electrophysiologically severe carpal
tunnel syndrome (CTS). Patients and Methods. We reviewed the long-term outcome of 40 patients with bilateral
severe CTS who underwent 80 CTRs (46 open, 34 endoscopic) between
2002 and 2012. The outcomes studied were patient-reported outcomes
of numbness resolution, the Boston Carpal Tunnel Questionnaire (BCTQ)
score, and patient satisfaction. Results. The mean follow-up was 9.3 years. Complete resolution of numbness
was reported by 93.8% of patients, persistent numbness by 3.8%,
and recurrent numbness by 2.5%. The mean BCTQ symptom score was
1.1 (. sd. 0.3; 1.0 to 2.55) and the mean Boston function
score was 1.15 (. sd. 0.46; 1.0 to 3.5). 72.5% of patients
were asymptomatic and had no functional impairment. Men had poorer
outcomes than women and patients <
55 years had poorer outcomes
than patients ≥ 55 years. All patients who had undergone endoscopic
CTR reported complete resolution of numbness compared with 89.1%
of those who had undergone open release (p = 0.047). There was no
significant difference in outcome between dominant and non-dominant
hands. Patient satisfaction rates were good. There were no adverse events. Conclusion. CTR has a favourable outcome and good rates of satisfaction,
even in patients with bilateral severe CTS at a mean of nine years
after surgery. Endoscopic CTR has a higher rate of numbness resolution
than open surgery. There were no significant differences in outcome
between the dominant and non-dominant hand. Cite this article:
Aims. Our purpose was to determine the quality of current randomised
controlled trials (RCTs) in hand surgery using standardised metrics. Materials and Methods. Based on five-year mean impact factors, we selected the six journals
that routinely publish studies of upper extremity surgery. Using
a journal-specific search query, 62 RCTs met our inclusion criteria.
Then three blinded reviewers used the Jadad and revised Coleman Methodology
Score (RCMS) to assess the quality of the manuscripts. Results. Based on the Jadad scale, 28 studies were of high quality and
34 were of low quality. Methodological deficiencies in poorly scoring
trials included the absence of rate of enrolment, no power analysis,
no description of withdrawal or dropout, and a failure to use validated
outcomes assessments with an independent investigator. Conclusion. A large number of RCTs in hand, wrist, and elbow surgery were
of suboptimal quality when judged against the RCMS and Jadad scales.
Even with a high level of evidence, study design and execution of
RCTs should be critically assessed. Methodological deficiencies
may introduce bias and lead to statistically underpowered studies. Cite this article:
Aims. The aims of this study were to evaluate the clinical and radiological
outcomes of the Universal-2 total wrist arthroplasty (TWA) in patients
with rheumatoid arthritis. Patients and Methods. This was a retrospective review of all 95 Universal-2 TWAs which
were performed in our institution between 2003 to 2012 in patients
with rheumatoid arthritis. A total of six patients were lost to
follow-up and two died of unrelated causes. A total of ten patients
had bilateral procedures. Accordingly, 75 patients (85 TWAs) were
included in the study. There were 59 women and 16 men with a mean
age of 59 years (26 to 86). The mean follow-up was 53 months (24
to 120). Clinical assessment involved recording pain on a visual
analogue score, range of movement, grip strength, the Quick Disabilities
of the Arm, Shoulder and Hand (DASH) and Wrightington wrist scores.
Any adverse effects were documented with particular emphasis on
residual pain, limitation of movement, infection, dislocation and
the need for revision surgery. Radiographic assessment was performed pre-operatively and at
three, six and 12 months post-operatively, and annually thereafter.
Arthroplasties were assessed for distal row intercarpal fusion and
loosening. Radiolucent zones around the components were documented
according to a system developed at our institution. Results. The mean worst pain was 8.1 (3 to 10) pre-operatively and 5.4
(0 to 10) at latest follow-up (p <
0.001). Movements were preserved
with mean dorsiflexion of 29. o . (0. o. to 70. o. )
and palmar flexion of 21. o. (0. o. to 50. o. ).
The mean grip strength was 4.8 kg (1.7 to 11.5) pre-operatively
and 10 kg (0 to 28) at final follow-up (p <
0.001). The mean
QuickDASH and Wrightington wrist scores improved from 61 (16 to
91) to 46 (0 to 89) and 7.9 (1.8 to 10) to 5.7 (0 to 7.8) (p <
0.001).
A total of six patients (7%) had major complications; three required
revision arthroplasty and three an arthrodesis. The Kaplan-Meier
probability of survival using removal of the components as the endpoint
was 91% at 7.8 years (95% confidence interval 84 to 91). Conclusion. The Universal-2 TWA is recommended for use in patients with rheumatoid
arthritis. Cite this article:
Aims. We performed a systematic review of the current literature regarding
the outcomes of unconstrained metacarpophalangeal joint (MCPJ) arthroplasty. Materials and Methods. We initially identified 1305 studies, and 406 were found to be
duplicates. After exclusion criteria were applied, seven studies
were included. Outcomes extracted included pre- and post-operative
pain visual analogue scores, range of movement (ROM), strength of
pinch and grip, satisfaction and patient reported outcome measures
(PROMs). Clinical and radiological complications were recorded.
The results are presented in three groups based on the design of
the arthroplasty and the aetiology (pyrocarbon-osteoarthritis (pyro-OA),
pyrocarbon-inflammatory arthritis (pyro-IA), metal-on-polyethylene
(MoP)). Results. Results show that pyrocarbon implants provide an 85% reduction
in pain, 144% increase of pinch grip and 13° improvements in ROM
for both OA and IA combined. Patients receiving MoP arthroplasties
had a reduction in pinch strength. Satisfaction rates were 91% and
92% for pyrocarbon-OA and pyrocarbon-IA groups, respectively. There were
nine failures in 87 joints (10.3%) over a mean follow-up of 5.5
years (1.0 to 14.3) for pyro-OA. There were 18 failures in 149 joints
(12.1%) over a mean period of 6.6 years (1.0 to 16.0) for pyro-IA.
Meta-analysis was not possible due to the heterogeneity of the studies
and the limited presentation of data. Conclusion. We would recommend prospective data collection for small joint
arthroplasties of the hand consisting of PROMs that would allow
clinicians to come to stronger conclusions about the impact on function
of replacing the MCPJs. A national joint registry may be the best
way to achieve this. Cite this article:
Aims. We conducted a study to determine whether radiological parameters
correlate with patient reported functional outcome, health-related
quality of life and physical measures of function in patients with
a fracture of the distal radius. Patients and Methods. The post-operative palmar tilt and ulnar variance at six weeks
and 12 months were correlated with the Patient Rated Wrist Evaluation,
Disabilities of the Arm, Shoulder and Hand, and EuroQol scores,
grip strength, pinch strength and range of movement at three, six
and 12 months for 50 patients (mean age 57 years; 26 to 85) having surgical
fixation, with either percutaneous pinning or reconstruction with
a volar plate, for a fracture of the distal radius. Results. Radiological parameters were found to correlate poorly with the
patient reported outcomes (r = 0.00 to 0.47) and physical measures
of function (r = 0.01 to 0.51) at all intervals. Conclusion. This study raises concerns about the use of radiological parameters
to determine management, and to act as a surrogates for successful
treatment, in patients with a fracture of the distal radius. Restoration
of ‘normal’ radiographic parameters may not be necessary to achieve
a satisfactory functional outcome for the patient. Cite this article:
Aims. Chronic conditions of the wrist may be difficult to manage because
pain and psychiatric conditions are correlated with abnormal function
of the hand. Additionally, intra-articular inflammatory cytokines
may cause pain. We aimed to validate the measurement of inflammatory cytokines
in these conditions and identify features associated with symptoms. Patients and Methods. The study included 38 patients (18 men, 20 women, mean age 43
years) with a chronic condition of the wrist who underwent arthroscopy.
Before surgery, the Self-Rating Depression Scale (SDS), Hand20 questionnaire
and a visual analogue scale (VAS) for pain were used. Cytokine and
chemokine levels in the synovial fluid of the wrist were measured
using enzyme-linked immunosorbent assays and correlations between
the levels with pain were analysed. Gene expression profiles of
the synovial membranes were assessed using quantitative polymerase
chain reaction. Results. Older patients had high pre-operative Hand20 scores. One-year
post-operative Hand20 and VAS scores and pre-operative VAS scores
correlated with SDS scores. Post-operative VAS scores negatively
correlated with the expression of nerve growth factor and SDS scores
positively correlated with the expression of tumour necrosis factor-alpha
and negatively correlated with the expression of tumour necrosis
factor-converting enzyme. Conclusion. There was a positive correlation between depression and chronic
conditions of the wrist. Levels of some cytokines correlate with
pain and depression. Additionally, cytokines may be important in
the assessment and treatment of chronic conditions of the wrist
and depression. Cite this article:
Aims. Total wrist arthrodesis (TWA) produces a spectrum of outcomes.
We investigated this by reviewing 77 consecutive TWA performed for
inflammatory and post-traumatic arthropathies, wrist instability
and as a salvage procedure. . Patients and Methods. All operations were performed by a single surgeon using a specifically
designed pre-contoured dorsally applied non-locking wrist arthrodesis
plate at a single centre. . Results. Median post-operative Buck-Gramcko Lohman (BGL), Disabilities
of the Arm, Shoulder and Hand and Patient Rated Wrist Evaluation
scores at six years (interquartile range (IQR) 3 to 11) were 9 (IQR
= 6 to 10), 19 (IQR = 7 to 45) and 13 (IQR = 1 to 31) respectively.
Polyarticular inflammatory arthritis and female gender were associated
with poorer patient-reported outcomes, although the effect of gender
was partly explained by higher rates of inflammatory disease among
women. Return to work was negatively influenced by workers’ compensation
and non-inflammatory wrist pathology. There was no difference in
complication rates for inflammatory and non-inflammatory indications. . Take home message: Polyarticular inflammatory arthritis is a
risk factor for adverse patient-reported outcomes in TWA. Furthermore,
when compared with patients without inflammatory arthritis, dorsally
applied pre-contoured plates can be used for wrist arthrodesis in
patients with inflammatory arthritis without an increased risk of complications. Cite this article:
Aims. The aim of this study was to compare the Push Ortho Thumb Brace
CMC and a custom-made orthosis in the treatment of patients with
primary osteoarthritis of the carpometacarpal joint of the thumb.
Our outcome measures were pain scores, tests of hand function, patient
satisfaction and patient preference. Patients and Methods. A multicentre crossover randomised controlled trial was conducted
which included 63 patients (44 women) with primary osteoarthritis
of the carpometacarpal joint of the thumb. Of these, 59 patients
with a mean age of 60.1 years (standard deviation 8.2), completed
the study. Patients used both orthoses for two weeks with a two-week washout
period in-between. Pain was measured on a 10-cm visual analogue
scale. Hand function was assessed using the Jebsen Taylor Hand Function
test, Nine Hole Peg Test, key grip, pinch grip and Functional Index
for Hand Osteoarthritis. Patient preference was assessed using the
Dutch version of the Quebec User Evaluation of Satisfaction with
Assistive Technology score. Results. Both orthoses resulted in a minor reduction in pain scores without
significant difference between the two orthoses. The Push Ortho
Thumb Brace CMC interfered less with key grip (p <
0.001) and
the Nine Hole Peg Test (p <
0.001) than the custom-made orthosis.
The Push Ortho Thumb Brace CMC had a higher patient satisfaction
(p <
0.001) and most patients preferred this orthosis for future
use. Conclusion. When considering an orthosis for osteoarthritis of the carpometacarpal
joint of the thumb, patients may prefer the Push Ortho Thumb Brace
CMC. Cite this article:
Aims. This study explores the epidemiology of patients with a fracture
of the scaphoid presenting to a regional teaching hospital. Patients and Methods. All patients with a confirmed fracture of the scaphoid over a
retrospective period between January 2010 and May 2013 were included.
Their demographics, deprivation status and when the fracture occurred
was noted and assessed. There were 415 fractures in 365 males and
50 females. Results. The incidence of fracture of the scaphoid was 12.4 in 100 000
each year in the general population. The mean age of the patients
was 22 years (nine to 35); the highest incidence was in males aged
between 15 and 19 years. We calculate the annual incidence in the
United Kingdom to be 7265 each year. Patients with the lowest socioeconomic status
had an incidence of 18.57 in 100 000 whereas the least deprived
patients had an incidence of 9.98 (p <
0.001). There was evidence
of a seasonal trend (p = 0.022) with the highest monthly rate found
in June (16.96 in 100 000 each year) and the lowest was in December
(7.61 in 100 000 each year). There were significantly fewer presentations of
fracture at the weekend (p <
0.001), and the highest incidence
was on Mondays. Most fractures occurred at the waist (64%) and tubercle
(18.1%). Take home message: In this large-scale epidemiological study,
we confirmed that young men are most at risk of sustaining a fracture
of the scaphoid, and report new factors in relation to social deprivation
and seasonality that influence scaphoid fractures. Cite this article:
Aims. The degree of displacement of a fracture of the distal radius
is an important factor which can be assessed using simple radiographic
measurements. Our aim was to investigate the reliability and reproducibility
of these measurements and to determine if they should be used clinically. Patients and Methods. A 10% sample was randomly generated from 3670 consecutive adult
patients who had presented to University Hospitals of Leicester
NHS Trust between 2007 and 2010 with a fracture of the distal radius.
Radiographs of the 367 patients were assessed by two independent
reviewers. Four measurements of displacement of the fracture were recorded
and the inter-observer correlation assessed using the intra-class
correlation coefficient. Results. Inter-observer correlation was high (>
0.8) for three of the
four measurements. Repeat measurements of a further randomly generated
10% sample (37) were made four weeks later to assess intra-observer
agreement, which was again high (>
0.8) for the same three parameters
(radial height, radial inclination and dorsal/palmar tilt). Correlation was
poor for articular step and gap. Conclusion. Radiographic assessment of radial angle, radial inclination and
dorsal/palmar tilt is a reliable method of determining the degree
of displacement of a fracture of the distal radius. Cite this article:
Arthritis of the wrist is a painful disabling
condition that has various causes and presentations. The traditional treatment
has been a total wrist fusion at a price of the elimination of movement.
However, forms of treatment which allow the preservation of movement
are now preferred. Modern arthroplasties of the wrist are still
not sufficiently robust to meet the demands of many patients, nor
do they restore normal kinematics of the wrist. A preferable compromise
may be selective excision and partial fusion of the wrist using
knowledge of the aetiology and pattern of degenerative change to
identify which joints can be sacrificed and which can be preserved. . This article provides an overview of the treatment options available
for patients with arthritis of the wrist and an algorithm for selecting
an appropriate surgical strategy. Cite this article:
We present an economic evaluation using data
from the Distal Radius Acute Fracture Fixation Trial (DRAFFT) to compare
the relative cost effectiveness of percutaneous Kirschner wire (K-wire)
fixation and volar locking-plate fixation for patients with dorsally-displaced
fractures of the distal radius. . The cost effectiveness analysis (cost per quality-adjusted life
year; QALY) was derived from a multi-centre, two-arm, parallel group,
assessor-blind, randomised controlled trial which took place in
18 trauma centres in the United Kingdom. Data from 460 patients
were available for analysis, which includes both a National Health
Service cost perspective including costs of surgery, implants and
healthcare resource use over a 12-month period after surgery, and
a societal perspective, which includes the cost of time off work
and the need for additional private care. . There was only a small difference in QALYs gained for patients
treated with locking-plate fixation over those treated with K-wires.
At a mean additional cost of £714 (95% confidence interval 588 to
865) per patient, locking-plate fixation presented an incremental
cost effectiveness ratio (ICER) of £89 322 per QALY within the first
12 months of treatment. Sensitivity analyses were undertaken to
assess the ICER of locking-plate fixation compared with K-wires.
These were greater than £30 000. . Compared with locking-plate fixation, K-wire fixation is a ‘cost
saving’ intervention, with similar health benefits. Cite this article:
There is no consensus on the benefit of arthroscopically
assisted reduction of the articular surface combined with fixation
using a volar locking plate for the treatment of intra-articular
distal radial fractures. In this study we compared the functional
and radiographic outcomes of fluoroscopically and arthroscopically
guided reduction of these fractures. Between February 2009 and May 2013, 74 patients with unilateral
unstable intra-articular distal radial fractures were randomised
equally into the two groups for treatment. The mean age of these
74 patients was 64 years (24 to 92). We compared functional outcomes
including active range of movement of the wrist, grip strength and Disabilities
of the Arm, Shoulder, and Hand scores at six and 48 weeks; and radiographic
outcomes that included gap, step, radial inclination, volar angulation
and ulnar variance. . There were no significant differences between the techniques
with regard to functional outcomes or radiographic parameters. The
mean gap and step in the fluoroscopic and arthroscopic groups were
comparable at 0.9 mm (standard deviation. (sd). 0.7) and
0.7 mm (. sd. 0.7) and 0.6 mm (. sd. 0.6) and 0.4 mm
(. sd. 0.5), respectively; p = 0.18 and p = 0.35). . Arthroscopic reduction conferred no advantage over conventional
fluoroscopic guidance in achieving anatomical reduction of intra-articular
distal radial fractures when using a volar locking plate. Cite this article:
This article is a systematic review of the published
literature about the biomechanics, functional outcome and complications
of intramedullary nailing of fractures of the distal radius. We searched the Medline and EMBASE databases and included all
studies which reported the outcome of intramedullary (IM) nailing
of fractures of the distal radius. Data about functional outcome,
range of movement (ROM), strength and complications, were extracted.
The studies included were appraised independently by both authors
using a validated quality assessment scale for non-controlled studies
and the CONSORT statement for randomised controlled trials (RCTs). The search strategy revealed 785 studies, of which 16 were included
for full paper review. These included three biomechanical studies,
eight case series and five randomised controlled trials (RCTs). . The biomechanical studies concluded that IM nails were at least
as strong as locking plates. The clinical studies reported that
IM nailing gave a comparable ROM, functional outcome and grip strength
to other fixation techniques. . However, the mean complication rate of intramedullary nailing
was 17.6% (0% to 50%). This is higher than the rates reported in
contemporary studies for volar plating. It raises concerns about
the role of intramedullary nailing, particularly when comparative
studies have failed to show that it has any major advantage over
other techniques. Further adequately powered RCTs comparing the
technique to both volar plating and percutaneous wire fixation are needed. Cite this article:
Wrist block has been used to provide pain relief
for many procedures on the hand and wrist but its role in arthroscopy
of the wrist remains unexplored. Chondrotoxicity has been a concern
with the intra-articular infiltration of local anaesthetic. We aimed
to evaluate and compare the analgesic effect of portal and wrist
joint infiltration with a wrist block on the pain experienced by
patients after arthroscopy of the wrist. A prospective, randomised, double-blind trial was designed and
patients undergoing arthroscopy of the wrist under general anaesthesia
as a day case were recruited for the study. Levo-bupivacaine was
used for both techniques. The effects were evaluated using a ten-point
visual analogue scale, and the use of analgesic agents was also
compared. The primary outcomes for statistical analyses were the
mean pain scores and the use of analgesia post-operatively. . A total of 34 patients (63% females) were recruited to the portal
and joint infiltration group and 32 patients (59% males) to the
wrist block group. Mean age was 40.8 years in the first group and
39.7 years in the second group (p >
0.05). Both techniques provided
effective pain relief in the first hour and 24 hours post-operatively
but wrist block gave better pain scores at bedtime on the day of
surgery (p = 0.007) and at 24 hours post-operatively (p = 0.006). . Wrist block provides better and more reliable analgesia in patients
undergoing arthroscopy of the wrist without exposing patients to
the risk of chondrotoxicity. Cite this article:
We conducted an observational radiographic study
to determine the inter- and intra-observer reliability of the AO classification
of fractures of the distal radius. Plain posteroanterior and lateral
radiographs of 456 patients with an acute fracture of the distal
radius were classified by a consultant orthopaedic hand specialist
and two specialist trainees, and the k coefficient for the inter-
and intra-observer reliability of the type, group and subgroup classification
was calculated. . Only the type of fracture (A, B or C) was found to provide substantial
intra-observer reliability (k . type. 0.65). The inclusion
of ‘group’ and ‘subgroup’ into the classification reduced the inter-observer
reliability to fair (k. group. 0.29, k. subgroup . =
0.28) and the intra-observer reliability to moderate (k. group. 0.53,
k. subgroup. 0.49). Disagreement was found to arise between
specific subgroups, which may be amenable to clarification. Cite this article:
We performed a retrospective study to determine
the effect of osteoporosis on the functional outcome of osteoporotic
distal radial fractures treated with a volar locking plate. Between
2009 and 2012 a total of 90 postmenopausal women with an unstable
fracture of the distal radius treated with a volar locking plate
were studied. Changes in the radiological parameters of 51 patients
with osteoporosis (group 1, mean age 66.9, mean T-score –3.16 (. sd. 0.56))
were not significantly different from those in 39 patients without
osteoporosis (group 2, mean age 61.1, mean T-score –1.72 (. sd. 0.57)).
The mean Disabilities of the Arm, Shoulder and Hand (DASH) score
at final follow-up was 11.5 (. sd. 12.2) in group 1 and 10.5
(. sd. 13.25) in group 2. The mean modified Mayo wrist score
at final follow-up was 79.0 (. sd. 14.04) in group 1 and 82.6
(. sd. 13.1) in group 2. However, this difference was not
statistically significant (p = 0.35 for DASH score, p = 0.2 for
modified Mayo wrist score). Univariable and multivariable logistic regression
analysis showed that only the step-off of the radiocarpal joint
was related to both a poor DASH and modified Mayo wrist score. Pearson’s
correlation coefficient showed a weak negative relationship only
between the
T-score and the change in volar tilt (intraclass coefficient –0.26,
p = 0.02). We found that osteoporosis does not have a negative effect on
the functional outcome and additional analysis did not show a correlation
between T-score and outcome. Cite this article:
We compared the ceiling effects of two patient-rating
scores, the Disability of the Arm, Shoulder and Hand (DASH) and
Patient-Rated Wrist Evaluation (PRWE), and a physician-rating score,
the Modified Mayo Wrist Score (MMWS) in assessing the outcome of
surgical treatment of an unstable distal radial fracture. A total
of 77 women with a mean age of 64.2 years (50 to 88) who underwent
fixation using a volar locking plate for an unstable distal radial fracture
between 2011 and 2013 were enrolled in this study. All completed
the DASH and PRWE questionnaires one year post-operatively and were
assessed using the MMWS by the senior author. The ceiling effects
in the outcome data assessed for each score were estimated. The data assessed with both patient-rating scores, the DASH and
PRWE, showed substantial ceiling effects, whereas the data assessed
with MMWS showed no ceiling effect. Researchers should be aware of a possible ceiling effect in the
assessment of the outcome of the surgical treatment of distal radial
fractures using patient-rating scores. It could also increase the
likelihood of a type II error. Cite this article:
We report a new surgical technique for the treatment
of traumatic dislocation of the carpometacarpal (CMC) joint of the
thumb. This is a tenodesis which uses part of the flexor carpi radialis. . Between January 2010 and August 2013, 13 patients with traumatic
instability of the CMC joint of the thumb were treated using this
technique. The mean time interval between injury and ligament reconstruction
was 13 days (0 to 42). The mean age of the patients at surgery was
38 years: all were male. . At a mean final follow-up of 26 months (24 to 29), no patient
experienced any residual instability. The mean total palmar abduction
of the CMC joint of the thumb was 61° and the mean radial abduction
65° The mean measurements for the uninjured hand were 66° (60° to
73°) and 68° (60° to 75°), respectively. The mean Kapandji thumb
opposition score was 8.5° (8° to 9°). The mean pinch and grip strengths
of the hand were 6.7 kg (3.4 to 8.2) and 40 kg (25 to 49), respectively.
The mean Disabilities of the Arm, Shoulder, and Hand questionnaire
score was 3 (1 to 6). Based on the Smith and Cooney score, we obtained
a mean score of 85 (75 to 95), which included four excellent, seven
good, and two fair results. Our technique offers an alternative method of treating traumatic
dislocation of the CMC joint of the thumb: it produces a stable
joint and acceptable hand function. Cite this article:
We report a new surgical technique of open carpal
tunnel release with subneural reconstruction of the transverse carpal
ligament and compare this with isolated open and endoscopic carpal
tunnel release. Between December 2007 and October 2011, 213 patients with carpal
tunnel syndrome (70 male, 143 female; mean age 45.6 years; 29 to
67) were recruited from three different centres and were randomly
allocated to three groups: group A, open carpal tunnel release with
subneural reconstruction of the transverse carpal ligament (n =
68); group B, isolated open carpal tunnel release (n = 92); and
group C, endoscopic carpal tunnel release (n = 53). At a mean final follow-up of 24 months (22 to 26), we found no
significant difference between the groups in terms of severity of
symptoms or lateral grip strength. Compared with groups B and C,
group A had significantly better functional status, cylindrical
grip strength and pinch grip strength. There were significant differences
in Michigan Hand Outcome scores between groups A and B, A and C,
and B and C. Group A had the best functional status, cylindrical
grip strength, pinch grip strength and Michigan Hand Outcome score. Subneural reconstruction of the transverse carpal ligament during
carpal tunnel decompression maximises hand strength by stabilising
the transverse carpal arch. Cite this article:
We conducted an anatomical study to determine
the best technique for transfer of the anterior interosseous nerve (AIN)
for the treatment of proximal ulnar nerve injuries. The AIN, ulnar
nerve, and associated branches were dissected in 24 cadaver arms.
The number of branches of the AIN and length available for transfer
were measured. The nerve was divided just proximal to its termination
in pronator quadratus and transferred to the ulnar nerve through
the shortest available route. Separation of the deep and superficial
branches of the ulnar nerve by blunt dissection alone, was also
assessed. The mean number of AIN branches was 4.8 (3 to 8) and the
mean length of the nerve available for transfer was 72 mm (41 to
106). The transferred nerve reached the ulnar nerve most distally
when placed dorsal to flexor digitorum profundus (FDP). We therefore
conclude that the AIN should be passed dorsal to FDP, and that the
deep and superficial branches of the ulnar nerve require approximately
30 mm of blunt dissection and 20 mm of sharp dissection from the
point of bifurcation to the site of the anastomosis. The use of this technique for transfer of the AIN should improve
the outcome for patients with proximal ulnar nerve injuries. Cite this article:
Penetration of the dorsal screw when treating
distal radius fractures with volar locking plates is an avoidable complication
that causes lesions of the extensor tendon in between 2% and 6%
of patients. We examined axial fluoroscopic views of the distal
end of the radius to observe small amounts of dorsal screw penetration,
and determined the ideal angle of inclination of the x-ray beam
to the forearm when making this radiological view. Six volar locking plates were inserted at the wrists of cadavers.
The actual screw length was measured under direct vision through
a dorsal approach to the distal radius. Axial radiographs were performed
for different angles of inclination of the forearm at the elbow. Comparing axial radiological measurements and real screw length,
a statistically significant correlation could be demonstrated at
an angle of inclination between 5° and 20°. The ideal angle of inclination
required to minimise the risk of implanting over-long screws in
a dorsal horizon radiological view is 15°. Cite this article:
Damage to the cartilage of the distal radioulnar
joint frequently leads to pain and limitation of movement, therefore repair
of this joint cartilage would be highly desirable. The purpose of
this study was to investigate the fixation of scaffold in cartilage
defects of this joint as part of matrix-assisted regenerative autologous
cartilage techniques. Two techniques of fixation of collagen scaffolds,
one involving fibrin glue alone and one with fibrin glue and sutures, were
compared in artificially created cartilage defects of the distal
radioulnar joint in a human cadaver. After being subjected to continuous
passive rotation, the methods of fixation were evaluated for cover
of the defect and pull out force. No statistically significant differences were found between the
two techniques for either cover of the defect or integrity of the
scaffold. However, a significantly increased mean pull out force
was found for the combined procedure, 0.665 N (0.150 to 1.160) versus 0.242
N (0.060 to 0.730) for glue fixation (p = 0.001). This suggests that although successful fixation of a collagen
type I/III scaffold in a distal radioulnar joint cartilage defect
is feasible with both forms of fixation, fixation with glue and
sutures is preferable. Cite this article:
The purpose of this study was to evaluate treatment
results following arthroscopic triangular fibrocartilage complex (TFCC)
debridement for recalcitrant ulnar wrist pain. According to the
treatment algorithm, 66 patients (36 men and 30 women with a mean
age of 38.1 years (15 to 67)) with recalcitrant ulnar wrist pain
were allocated to undergo ulnar shortening osteotomy (USO; n = 24),
arthroscopic TFCC repair (n = 15), arthroscopic TFCC debridement
(n = 14) or prolonged conservative treatment (n = 13). The mean
follow-up was 36.0 months (15 to 54). Significant differences in
Hand20 score at 18 months were evident between the USO group and
TFCC debridement group (p = 0.003), and between the TFCC repair
group and TFCC debridement group (p = 0.029). Within-group comparisons showed
that Hand20 score at five months or later and pain score at two
months or later were significantly decreased in the USO/TFCC repair
groups. In contrast, scores in the TFCC debridement/conservative
groups did not decrease significantly. Grip strength at 18 months
was significantly improved in the USO/TFCC repair groups, but not
in the TFCC debridement/conservative groups. TFCC debridement shows
little benefit on the clinical course of recalcitrant ulnar wrist
pain even after excluding patients with ulnocarpal abutment or TFCC
detachment from the fovea from the indications for arthroscopic
TFCC debridement. Cite this article:
There is conflicting evidence about the functional
outcome and rate of satisfaction of super-elderly patients (≥ 80 years
of age) after carpal tunnel decompression. We compiled outcome data for 756 patients who underwent a carpal
tunnel decompression over an eight-year study period, 97 of whom
were super-elderly, and 659 patients who formed a younger control
group (<
80 years old). There was no significant difference between
the super-elderly patients and the younger control group in terms
of functional outcome according to the mean (0 to 100) QuickDASH
score (adjusted mean difference at one year 1.8; 95% confidence
interval (CI) -3.4 to 7.0) and satisfaction rate (odds ratio (OR)
0.78; 95% CI 0.34 to 1.58). Super-elderly patients were, however,
more likely to have thenar muscle atrophy at presentation (OR 9.2,
95% CI 5.8 to 14.6). When nerve conduction studies were obtained,
super-elderly patients were more likely to have a severe conduction deficit
(OR 12.4, 95% CI 3.0 to 51.3). Super-elderly patients report functional outcome and satisfaction
rates equal to those of their younger counterparts. They are more
likely to have thenar muscle atrophy and a severe nerve conduction
deficit at presentation, and may therefore warrant earlier decompression. Cite this article:
The aims of this study were to assess the efficacy
of a newly designed radiological technique (the radial groove view)
for the detection of protrusion of screws in the groove for the
extensor pollicis longus tendon (EPL) during plating of distal radial
fractures. We also aimed to determine the optimum position of the
forearm to obtain this view. We initially analysed the anatomy of
the EPL groove by performing three-dimensional CT on 51 normal forearms.
The mean horizontal angle of the groove was 17.8° (14° to 23°).
We found that the ideal position of the fluoroscopic beam to obtain
this view was 20° in the horizontal plane and 5° in the sagittal
plane. We then intra-operatively assessed the use of the radial groove
view for detecting protrusion of screws in the EPL groove in 93
fractures that were treated by volar plating. A total of 13 protruding
screws were detected. They were changed to shorter screws and these
patients underwent CT scans of the wrist immediately post-operatively.
There remained one screw that was protruding. These findings suggest
that the use of the radial groove view intra-operatively is a good
method of assessing the possible protrusion of screws into the groove
of EPL when plating a fracture of the distal radius. Cite this article:
The aim of this study was to determine the effect
of a Galeazzi fracture on the strength of pronation and supination at
a mean of two years after surgical treatment. The strength of pronation
and supination was measured in varying rotational positions of the
forearm of ten male patients (mean age 38.9 years (21 to 64)) who
had undergone plate fixation for a Galeazzi fracture. The stability
of the distal radioulnar joint was assessed, and a clinical assessment using
the quick-Disabilities of the Arm Shoulder and Hand (quickDASH)
questionnaire and patient-related wrist examination (PRWE) scores
was undertaken. In addition, the strength of pronation and supination
was measured in a male control group of 42 healthy volunteers (mean
age 21.8 years (18 to 37)). . The mean absolute loss of strength of supination in the injured
compared with the non-injured arm throughout all ranges of forearm
rotation was 16.1 kg (. sem. 5.3), corresponding to a relative
loss of 12.5% (95% confidence interval (CI) 3.6 to 21.4). For the
strength of pronation, the mean loss was 19.1 kg (. sem. 4.5),
corresponding to a relative loss of 27.2% (95% CI 14.2 to 40.1).
Loss of strength of supination following a Galeazzi fracture correlated with
poor quickDASH (p = 0.03) and PRWE scores (p <
0.01). Loss of strength of pronation (27.2%), and of supination (12.5%)
in particular, after a Galeazzi fracture is associated with worse
clinical scores, highlighting the importance of supination of the
forearm in function of the upper limb. Cite this article:
In Canada, Dupuytren's contracture is managed
with partial fasciectomy or percutaneous needle aponeurotomy (PNA).
Injectable collagenase will soon be available. The optimal management
of Dupuytren’s contracture is controversial and trade-offs exist
between the different methods. Using a cost-utility analysis approach,
our aim was to identify the most cost-effective form of treatment
for managing Dupuytren’s contracture it and the threshold at which
collagenase is cost-effective. We developed an expected-value decision
analysis model for Dupuytren’s contracture affecting a single finger,
comparing the cost-effectiveness of fasciectomy, aponeurotomy and collagenase
from a societal perspective. Cost-effectiveness, one-way sensitivity
and variability analyses were performed using standard thresholds
for cost effective treatment ($50 000 to $100 000/QALY gained).
Percutaneous needle aponeurotomy was the preferred strategy for
managing contractures affecting a single finger. The cost-effectiveness
of primary aponeurotomy improved when repeated to treat recurrence.
Fasciectomy was not cost-effective. Collagenase was cost-effective
relative to and preferred over aponeurotomy at $875 and $470 per
course of treatment, respectively. . In summary, our model supports the trend towards non-surgical
interventions for managing Dupuytren’s contracture affecting a single
finger. Injectable collagenase will only be feasible in our publicly
funded healthcare system if it costs significantly less than current
United States pricing. Cite this article:
