Radiological outcomes following surgical fixation with wires versus moulded cast for patients with a dorsally displaced fracture of the distal radius: a radiographic analysis from the DRAFFT2 trial.

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.

Patterns of recontracture after surgical correction of Dupuytren disease.

PURPOSE: To study the evolution of deformity of the proximal interphalangeal joint over 5 years after good surgical correction of Dupuytren-induced contracture. METHODS: We assessed 63 patients (72 fingers; 69 hands) with Dupuytren disease for the degree of contracture, its correction after surgery, and the range of movement at the proximal interphalangeal joints at 3 and 6 months, and 1, 3, and 5 years after fasciectomy with or without the use of a firebreak graft. We investigated associations between the recurrence of contracture and preoperative patient and surgical factors. RESULTS: There were 4 patterns of evolution of contracture after surgical correction. A total of 31 patients (33 hands) showed good improvement that was maintained for 5 years (minimal recontracture group). Twenty patients (23 hands) showed good initial improvement, which mildly worsened (< 20°) but was then maintained over 5 years (mild early recontracture group). Four patients (5 hands) worsened in first 3 months after surgery (> 20°) but there was no further worsening (severe early recontracture group). Eight patients (8 hands) worsened progressively over 5 years (progressive recontracture group). Worsening of contracture more than 6° between 3 and 6 months after surgery predicted progressive recontracture at 5 years. CONCLUSIONS: Recurrence of contracture (not disease recurrence) could be predicted as early as 6 months after surgery for Dupuytren disease.

The onset, progress and factors influencing degenerative arthritis of the wrist following scaphoid fracture non-union.

BACKGROUND/AIMS: Scaphoid non-union causes osteoarthritis but factors associated are poorly understood. We investigated the rate of osteoarthritis after scaphoid fracture non-union, and if duration and fracture location influenced arthritis and its severity. METHODS: This retrospective cross-sectional observational study of 278 consecutive cases with scaphoid fracture non-union retrieved data on demographics, non-union duration, fracture location, dorsal intercalated segment instability (DISI), severity and distribution of wrist arthritis. Patient Evaluation Measure (PEM) and Quality of Life assessed impact on patients. Regression models investigated prediction of osteoarthritis by different variables. Time-to-event analysis investigated osteoarthritis evolution. Missing (MAR) data for the PEM and QoL was imputed and analysed. RESULTS: 278 patients, 246 males, aged 27.9 years (range 11 to 78 years), with a scaphoid fracture non-union confirmed on computed tomography (CT) scans (243) and plain radiographs (35) were reviewed. The interval between injury and imaging was 3.3 years (SD 5.9 years; range 0.1-45). The fracture was proximal to the ridge in 162, distal to the ridge in 83 and in the proximal 20% in 33. DISI (RLA ≥ 10°) occurred in 93.5% (260/278). Osteoarthritis was identified in 62.2% (173/278), and we classified a SNAC pattern in 93.6% (162/173). Of these, 100 (61.7%) had SNAC 1, 22 (13.6%) SNAC 2, 17 (10.5%) SNAC 3, and 23 (14.2%) SNAC 4. The mean duration in years for SNAC 1, 2, 3 and 4 were 2.5, 6.0, 8.2, and 11.3 years respectively. In fractures proximal to the ridge, 50% had arthritis in 2.2 years. Whereas in proximal pole, and distal to the ridge, 50% developed in 3.8 and 6.6 years, respectively. The PEM score was 42.8% (SD 18.9%) in those without arthritis and 48.8% (SD 21.5%) in those with arthritis. The mean QoL was 0.838 in patients without SNAC and 0.792 with SNAC. CONCLUSION: Scaphoid fracture non-union caused early carpal collapse, majority had osteoarthritis usually observed within a year following injury and occurred earliest in proximal waist fractures. Distribution of osteoarthritis (SNAC stage) may not always follow a distinctive pattern, as previously described.

Utilising the impact of COVID-19 on trauma throughput to adapt elective care models for more efficient trauma care.

BACKGROUND: Coronavirus disease 2019 (COVID-19) has necessitated adaptations in local trauma services, with implementation of novel methods of practice, strategic adaptations, and shifting of resource management. Many of these may serve the driver for landmark changes to future healthcare provision. AIM: To analyse the impact of COVID-19 on service provision by comparing throughput and productivity metrics with preceding years to identify differences in practice that were successful, cost-effective, and sustainable. METHODS: We quantified orthopaedic trauma care provision at a single University Teaching Hospital over a three consecutive year period, from 1st January 2018 to 31st December 2020. Each year was split into four phases based on the 2020 national COVID-19 pandemic periods. We quantitatively analysed change in rates of inpatient trauma operative case load, sub-specialty variation, theatre throughput, and changes in management strategy. Qualitative analysis was based on multidisciplinary team interviews to highlight changes to care pathways. RESULTS: Of 1704 cases were admitted in 2020, 11.9% and 12.4% fewer than 2019 and 2018, respectively. During phase 1, hip fractures encompassed the majority (48.8%) of trauma throughput, with all other subspecialties seeing a reduction. Mean length of stay was shorter during phase 1 (5.7 d); however, the time in theatre was longer (144.3 min). Both, Charlson (0.90) and Elixhauser (1.55) Comorbidity Indices indicated the most co-morbid admissions during 2020 phase 1. CONCLUSION: COVID-19 has resulted in a paradigm shift in how care is accessed and delivered, with many evolving changes and adaptations likely to leave an impression upon healthcare provision in the future.
