ABSTRACT
Background: BOAST (British Orthopaedic Association Standards for Trauma & Orthopaedics) guidelines recommended that during the coronavirus pandemic most upper limb fractures should be treated conservatively, and removable casts should be used, where possible. As a result, our district general hospital started using a new soft combination (soft-combi) casting technique for conservative management of distal radius fractures (DRFs) in an attempt to reduce follow-up attendances.Aims: To assess if radiological outcomes of soft-combi casts are better or worse than previously used rigid casts for DRFs.Methods: 20 DRFs treated with soft-combi casts were compared with 20 DRFs treated with the old rigid cast types. Radiological parameters were measured pre-manipulation, post-manipulation, at 2-week follow-up, and at final follow-up. Statistical analysis was performed to assess for significant differences seen at follow-up between the groups.Results: The mean loss of volar angulation seen at 2-week follow-up was 4.9 degrees for the rigid casts vs. 1.5 degrees for the soft-combi casts (p=0.158). The mean loss of radial height after 2 weeks was 0.2 mm vs 0.5 mm (p=0.675), and the mean loss of radial inclination was 2.0 degrees vs 1.0 degrees (p=0.349), respectively.Conclusion: The soft-combi casts appeared to be equally effective at maintaining the reduction of DRFs compared to their rigid counterparts, as no statistically significant difference was seen in our study. We can be reassured that continued use of these removable casts in the current climate is unlikely to have a detrimental effect on outcomes for DRFs.
