Although surgical division of the transverse carpal ligament is the operative treatment of choice for carpal tunnel syndrome (CTS), controversy exists about the immediate postoperative treatment regimen. Splinting for up to 6 weeks after surgery is recommended by some investigators. We therefore evaluated effectiveness of splinting after open carpal tunnel surgery by a randomized, controlled trial. Fifty consecutive patients with clinically and electrophysiologically confirmed idiopathic CTS were assigned to open carpal tunnel release and randomized to receiving a light bandage (25 patients) or a bulky dressing with a volar splint (25 patients) for 2 days each. All patients were followed up at 3 months. Parameters retrieved were pain as measured using a visual analog scale, two-point discrimination, and grip strength, and nerve conduction studies. At follow-up, all patients reported definite improvement of symptoms, but there was no statistically significant difference between the two groups for any of our outcome measures. Thus, postoperative splinting after open carpal tunnel release does not yield any benefit to eventual outcome. In fact, it adds to the overall operating time and can safely be abandoned.
