Does wrist immobilization following open carpal tunnel release improve functional outcome? A literature review.
Carpal Tunnel Syndrome (CTS) is a compressive neuropathy of the median nerve in the carpal tunnel. It is the most common peripheral entrapment neuropathy. The surgical management includes dividing the flexor retinaculum to decompress the median nerve. Post-operative mobilization of the wrist is controversial. Some surgeons splint the wrist for 2-4 weeks whilst others encourage early mobilization. The literature has been inconclusive as to which method is most beneficial. The purpose of this study is to review the literature regarding the effectiveness of wrist immobilization following open carpal tunnel decompression. We reviewed all published clinical trials claiming to evaluate the mobility status following open carpal tunnel release. Studies not in the English language as well as those with small number of patients (n < 30) were excluded. There were five studies that fulfilled the eligibility criteria and were included in this review. We conclude that there is no beneficial effect from post-operative immobilization after open carpal tunnel decompression when compared to early mobilization.
