Use of a splint following open carpal tunnel release: a comparative study

This study was undertaken to compare the clinical effectiveness and costs of postoperative splintage and late rehabilitation with a bulky bandage dressing versus early rehabilitation after carpal tunnel release. In this comparative study, 46 patients were randomly divided into 2 groups. In each group, 3 patients were excluded because of improper follow-up, leaving a total of 40 patients. Group 1 used a splint (exercises given 3 wk postoperatively) and group 2 was given a bulky bandage (exercises provided immediately) after open release. Patients were assessed preoperatively and at the first and third postoperative months with the Questionnaire of Levine for Clinical Assessment of Carpal Tunnel Syndrome. The 2 groups were similar in terms of preoperative functional status scores and in controls at the first and third months (P=.549, P=.326, P=.190). When both groups were compared, no statistical significance was found regarding symptom severity scale scores preoperatively and at the first postoperative month (P=.632 vs P=.353). At the third month, scores were lower in favor of group 2 (P=.023). Additionally, 16 of 20 patients (80%) in group 1 reported a heavy feeling and discomfort caused by the splint. This problem was not reported by the patients in group 2. The cheapest splint on the market was 9 times more expensive than a bulky dressing. The investigators concluded that postoperative immobilization with a splint has no detectable benefits. Use of bulky dressings and abandonment of the use of postoperative splints may prevent unnecessary expenditures without sacrificing patient comfort or compromising the course of healing in carpal tunnel surgery.
