A detailed literature search was performed to investigate whether the increasing importance of evidence-based hand surgery is reflected in the actual status of Cochrane reviews. Fourteen Cochrane reviews were found and evaluated. Of these, five reviews were in the field of distal radial fractures and four concerned carpal tunnel syndrome. Cochrane reviews were also found for antibiotic treatment, rehabilitation after flexor tendon injuries, mallet finger injuries, little finger metacarpal neck fractures and thumb joint arthritis. All 14 reviews were compromised by methodological flaws and significant clinical heterogeneity of the included studies. Within most reviews the underlying evidence was insufficient and only a very limited number of clinical recommendations could be made. In conclusion, the existing Cochrane reviews in the field of hand surgery show both an increasing interest in establishing systematically summarised knowledge and an enormous demand for good-quality randomised controlled trials.
