Randomised controlled trials in hand surgery: a scoping review

Abstract

Objectives To identify the evidence gaps that exist regarding the efficacy or effectiveness of hand surgery. Setting A scoping review. We systematically searched MEDLINE, Embase and CENTRAL databases to identify all hand surgical randomised controlled trials from inception to 7 November 2020. Results Of the 220 identified randomised controlled trials, none were fundamental efficacy trials, that is, compared surgery with placebo surgery. 172 (78%) trials compared the outcomes of different surgical techniques, and 143 (65%) trials were trauma related. We identified only 47 (21%) trials comparing surgery with non-operative care or injection. Conclusion The evidence supporting use of surgery especially for chronic hand conditions is scarce. To determine optimal care for people with hand conditions, more resources should be aimed at placebo-controlled trials and pragmatic effectiveness trials comparing hand surgery with non-operative care.
