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

Metacarpal fractures represent up to 33% of all hand fractures; of which the majority can be treated non-operatively. Previous research has shown excellent putcomes with non-operative treatment yet surgical stabilisation is recommended to avoid malrotation and symptomatic shortening. It is unknown whether operative is superior to non-operative treatment in oblique or spiral metacarpal shaft fractures. The aim of the study was to compare non-operative treatment of mobilisation with open surgical stabilisation. 42 adults (≥ 18 years) with a single displaced oblique or spiral metacarpal shaft fractures were randomly assigned in a 1:1 pattern to either non-operative treatment with free mobilisation or operative treatment with open reduction and fixation with lag screws in a prospective study. The primary outcome measure was grip-strength in the injured hand in comparison to the uninjured hand at 1-year follow-up. The Disabilities of the Arm, Shoulder and Hand Score, ranges of motion, metacarpal shortening, complications, time off work, patient satisfaction and costs were secondary outcomes. All 42 patients attended final follow-up after 1 year. The mean grip strength in the non-operative group was 104% (range 73–250%) of the contralateral hand and 96% (range 58–121%) in the operatively treated patients. Mean metacarpal shortening was 5.0 (range 0–9) mm in the non-operative group and 0.6 (range 0–7) mm in the operative group. There were five minor complications and three revision operations, all in the operative group. The costs for non-operative treatment were estimated at 1,347 USD compared to 3,834USD for operative treatment; sick leave was significantly longer in the operative group (35 days, range 0–147) than in the non-operative group (12 days, range 0–62) (p=0.008). When treated with immediate free mobilization single, patients with displaced spiral or oblique metacarpal shaft fractures have outcomes that are comparable to those after operative treatment, despite some metacarpal shortening. Complication rates, costs and sick leave are higher with operative treatment. Early mobilisation of spiral or long oblique single metacarpal fractures is the preferred treatment.

Our aim was to ascertain if K-wire configuration had any influence on the infection and complication rate for base of 4th and 5th metacarpal fractures. We hypothesised that in individuals whose wires crossed the 4th and 5th carpometacarpal joint (CMCJ), the rate of complications and infection would be higher. Data was retrospectively analysed from a single centre. 106 consecutive patients with a base of 5th (with or without an associated 4th metacarpal fracture) were analysed between October 2016 and May 2021. Patients were split into two groups for comparison; those who did not have K-wires crossing the CMCJ's and those in whose fixation had wires crossing the joints. Confounding factors were accounted for and Statistical analysis was performed using SPSS version 20 software. Of 106 patients, 60 (56.6%) patients did have K-wires crossing the CMCJ. Wire size ranged from 1.2-2.0 with 65 individuals (65.7%) having size 1.6 wires inserted. The majority of patients, 66 (62.9%) underwent fixation with two wires (range 1-4). The majority of infected cases (88.9%) were in patients who had k-wires crossing the CMCJ, this trended towards clinical significance (p=0.09). Infection was associated with delay to theatre (p=0.002) and longer operative time (p=0.002). In patients with a base of 4th and 5th metacarpal fractures, we have demonstrated an increased risk of post-operative infection with a K-wire configuration that crosses the CMCJ. Biomechanical studies would be of use in determining the exact amount of movement across the CMCJ, with the different K-wire configuration in common use, and this will be part of a follow-up study

Our aim was to explore factors associated with early post operative infection for surgically managed base of 4th/5th metacarpal fractures. We hypothesised that K-wires crossing the 4th and 5th carpometacarpal joint (CMCJ) would be associated with an increased risk of post-operative infection. Data from consecutive patients requiring surgical fixation for a base of 4th/5th metacarpal fracture from October 2016 to May 2021 were collected. Patient demographics, time to surgery, length of surgery, operator experience, use of tourniquet, intra-operative antibiotics, number and thickness of K-wire used, as well as whether or not the K-wires crossed CMCJ joints were recorded. Factors associated with post operative infection were assessed using Chi Squared test and univariable logistic regression using R studio. Of 107 patients, 10 (9.3%) suffered post operative infection. Time to surgery (p 0.006) and length of operation (p=0.005) were higher in those experiencing infection. There was a trend towards higher risk of infection seen in those who had K-wires crossed (p=0.06). On univariable analysis, patients who had wires crossed were >7 times more likely to experience infection than those who didn't (OR 7.79 (95% CI, 1.39 - 146.0, p=0.056). Age, smoking, K-wire size, number of K-wires used, intraoperative antibiotics, tourniquet use and operator experience were not associated with infection. In patients with a base of 4th/5th metacarpal fractures requiring surgical fixation, we find an increased risk of post-operative infection associated with K-wires crossing the CMCJ, which has implications for surgical technique. Larger prospective studies would be useful in further delineating these findings

Abstract. Objectives. 1. To describe the epidemiology of metacarpal shaft fractures (MSF) in adults. 2. To evaluate the variation in practice and document complications following usual care. 3. To explore factors associated with treatment modality. 4. To document hospital resource use following MSF. Methods. A multi-centre, retrospective, cross-sectional study of MSF at six centres. The healthcare records, operative notes and imaging of adults presenting within 10 days of a MSF, affecting the second to fifth metacarpal between 1st August 2016 to 31st July 2017, were reviewed. Total number of Emergency Department (ED) attendances were used to calculate prevalence. Data analyses are primarily descriptive with 95% confidence intervals to quantify uncertainty in estimates. Results. Of 837, 212 ED attendances, 793 patients (75% male, 25% female), with 897 MSF were eligible, a prevalence of 0.1%. The median age was 27 years (16–97); the highest incidence was in males aged between 16 and 24 years. The most common fracture pattern was transverse. While 83% were treated non-surgically overall, this varied across centres. Twelve different types of non-surgical and six different types of surgical treatment were used. Multi-fragmentary fracture patterns were most likely to be treated surgically and long oblique least likely. Fracture pattern, complexity, displacement and age were associated with treatment modality. Patients treated surgically required more radiographs, longer radiographic and outpatient follow-up and were more likely to be referred for therapy. 5% (39/793) experienced a complication. 20% (160/783) failed to attend at least one or more clinic appointments. Conclusions. MSF are a common injuries, predominantly affecting young males of working age. There is variation in mode and type of treatment, with the majority treated non-surgically in the selected centres. Despite a low complication rate, they require considerable secondary care resources. Further research into the optimal treatment modality for these injuries is needed. Declaration of Interest.

Aims

Virtual fracture clinics (VFCs) are advocated by recent British Orthopaedic Association Standards for Trauma and Orthopaedics (BOASTs) to efficiently manage injuries during the COVID-19 pandemic. The primary aim of this national study is to assess the impact of these standards on patient satisfaction and clinical outcome amid the pandemic. The secondary aims are to determine the impact of the pandemic on the demographic details of injuries presenting to the VFC, and to compare outcomes and satisfaction when the BOAST guidelines were first introduced with a subsequent period when local practice would be familiar with these guidelines.

Introduction and Purpose. Metacarpal fractures constitute approximately one third of all hand fractures. The majority of these fractures are treated by conservative non-surgical methods. The aim of this study is to obtain the appropriate anatomical alignment of the fracture with dynamic metacarpal stabilization splint (DMSS) and to maintain the proper bone anatomy until the union is achieved. In addition, by comparing this method with short arm plaster splint (SAPS) application, it is aimed to evaluate whether patients are superior in terms of comfort, range of motion (ROM) and grip strength. Materials and Methods. In our study, SAPS or DMSS was applied to the patients with 5th metacarpal neck fracture randomly after fracture reduction and followed for 3 months. A total of 119 patients with appropriate criteria were included in the study. Radiological alignment of the fracture and amount of joint movements were evaluated during follow-up. Grip strength was evaluated with Jamar dynamometer. EQ-5D-5L and VAS scores were used for clinical evaluation. Results. 103 patients completed their follow-up. 51 patients were treated with SAPS and 52 patients were treated with DMSS. The mean age of the SAPS was 29.5 (SD ± 9.4; 16–53 years) and the mean age of the DMSS group was 27.8 (SD ± 11.6; 16–63). Pressure sores was seen in 5 patients in the DMSS group, while no pressure sore was seen in the SAPS (p = 0.008). There was no significant difference between the two groups in the VAS scores at all times. There was no significant difference between the mean dorsal cortical angulation (DCA) before the reduction, after the reduction and at the third month follow-ups. There was no statistically significant difference between the length of metacarps at first admittion before reduction, after reduction and at third month follow-ups. When the grip strength of the two groups were compared as a percentage, the grip strength of the patients in the DMSS group was found to be higher at 1st month, 2nd month and 3rd month (p <0.001). When the ROM values of the patients were evaluated, DMSS group had a higher degree of ROM in the first month compared to the SAPS group (p <0.001). No statistically significant difference was detected among groups at third month in the ROM of the IP and MP joints. However, wrist ROM was statistically higher in DMSS group at 3rd month (p <0.05). There was a statistically significant difference between EuroQol scores in favor of DMSA group (p <0.05). Discussion and Conclusion. In stable 5th metacarpal neck fractures, DMSA is as effective as SAPS to maintain bone anatomy. In addition, DMSA can be preferred for fixation plaster splint or circular plaster applications for the prevention of reduction in boxer fractures, with the advantage of having high clinical scores, which is an indication of early acquisition of grip strength, ease of use and patient comfort

Background

Due to the overwhelming demand for trauma services, resulting from increasing emergency department attendances over the past decade, virtual fracture clinics (VFCs) have become the fashion to keep up with the demand and help comply with the BOA Standards for Trauma and Orthopaedics (BOAST) guidelines. In this article, we perform a systematic review asking, “How useful are VFCs?”, and what injuries and conditions can be treated safely and effectively, to help decrease patient face to face consultations. Our primary outcomes were patient satisfaction, clinical efficiency and cost analysis, and clinical outcomes.

Aims

We quantitatively compared the 3D bone density distributions on CT scans performed on scaphoid waist fractures subacutely that went on to union or nonunion, and assessed whether 2D CT evaluations correlate with 3D bone density evaluations.
