Distal radius fractures: an evidence-based approach to assessment and management.

Distal radius fractures account for one in five bony injuries in both primary and secondary care. These are commonly the result of a fall on outstretched hands or high-energy trauma. On assessment, clinicians should determine the mechanism of injury, associated bony or soft tissue injuries, and neurovascular symptoms. Investigations should always include radiographs to evaluate for intra-articular involvement and fracture displacement. Owing to the heterogeneous injury patterns and patient profiles, the preferred management should consider the severity of the fracture, desired functional outcome and patient comorbidities. Non-operative management in select patients can give good results, especially in older adults. Immobilisation with or without reduction forms the mainstay of non-operative treatment. Surgical management options include closed reduction and application of a cast, percutaneous K-wires, open reduction and internal fixation with plates, or external fixation. Patients should be encouraged to mobilise as soon as it is safe to do so, to prevent stiffness. Median nerve compression is the most common complication followed by tendon rupture, arthrosis and malunion. This article outlines the British Orthopaedic Association Standards for Trauma and Orthopaedics for the management of distal radius fractures.

Assessment of Distal Radius Fracture Complications Among Adults 60 Years or Older: A Secondary Analysis of the WRIST Randomized Clinical Trial.

Importance: Complications affect treatment outcomes and quality of life in addition to increasing treatment costs. Objectives: To evaluate complication rates after the treatment of a distal radius fracture, to determine whether the rate or complication type is associated with treatment method, and to determine predictors of complications. Design, Setting, and Participants: The multicenter Wrist and Radius Injury Surgical Trial (WRIST), a randomized clinical trial, enrolled participants from April 10, 2012, to December 31, 2016. The study included 304 adults 60 years or older with isolated unstable distal radius fractures; 187 were randomized and 117 opted for casting. The study was conducted at 24 health systems in the United States, Canada, and Singapore. Data for this secondary analysis were collected from April 24, 2012, to February 28, 2018. Interventions: Participants opting for surgery were randomized to receive the volar locking plate system (n = 65), percutaneous pinning (n = 58), or bridging external fixation with or without supplemental pinning (n = 64). Patients who chose not to have surgery (n = 117) were not randomized and were enrolled for casting. Main Outcomes and Measures: Complication rate. Results: The WRIST enrolled a total of 304 participants, of whom 8 casting group participants were later found to be ineligible and were excluded from the analysis, leaving 296 participants. Randomized participants' mean (SD) age was 68 (7.2) years, 163 (87%) were female, and 165 (88%) were white. Casting participants' mean (SD) age was 75.6 (9.6) years, 93 (84%) were female, and 85 (85%) were white. The most common type of complications varied by treatment. Twelve of 65 participants (18.5%) in the internal fixation group reported a median nerve compression, while 16 of 26 participants (25.8%) who received external fixation and 13 of 56 participants (23.2%) who received pinning sustained pin site infections. Compared with the internal fixation group, complication rate for any severity complication was higher in participants who initially received casting (adjusted rate ratio, 1.88; 95% CI, 1.22-2.88), whereas the rate for moderate complications was higher in the external fixation group (adjusted rate ratio, 2.52; 95% CI, 1.25-5.09). Conclusions and Relevance: The distal radius fracture treatment decision-making process for older patients should incorporate a complication profile for each treatment type. For example, external fixation and pinning could be used for patients after apprising them of pin site infection risk. Internal fixation can be done in patients with high functional demands who are willing to receive surgery. Internal fixation use should be substantiated owing to the time and cost involved.

Association between body composition and median neuropathy in patients with physical disabilities.

BACKGROUND: Patients with physical disabilities more often have median neuropathies of the wrist and more than 70% of wheelchair users are overweight or obese. AIM: To explore the effects of body composition on the occurrence of distal median neuropathy and to search for the best probabilistic cutoff value of indicators to predict the likelihood of developing distal median neuropathy in patients with physical disabilities. DESIGN: A prospective study. SETTING: A 1-day annual physical checkup program for employees of a social welfare organization. POPULATION: In total, 72 patients with a physical disability (mean age ± SD, 40.0 ± 8.8 years; 40 women). METHODS: Using electrophysiologic testing to assess distal median nerve function and using a dual-energy X-ray absorptiometry examination to assess body composition. The formula for leg exercise burden index (EBI) was: leg EBI = body fat mass of both legs/lean tissue mass of both legs. RESULTS: The risk of developing a low median sensory nerve conduction velocity in the wrist-to-palm segment (< 43 m/s) was greater for patients with a higher leg EBI, yielding an adjusted odds ratio of 6.88 (P < 0.005). The body mass index (BMI) and being a wheelchair user were predictors of developing long median distal motor latency (> 4 ms). Using receiver operating characteristic analyses, we determined that patients with a physical disability were likely to develop distal median sensory neuropathy if they had a leg EBI of ≥ 0.943 and were likely to develop distal median motor neuropathy if they had a BMI of ≥ 24.5 kg/m2. CONCLUSION: The leg EBI is a predictor of having distal median sensory neuropathy among patients with a physical disability. CLINICAL REHABILITATION IMPACT: The value of the leg EBI can be useful information for identifying risk of distal median sensory neuropathy in patients with a physical disability.
