We compared the clinical outcomes of post-trapeziectomy protocols according to their duration. The main hypothesis was that there would be no significant difference in postoperative function whether immobilization duration was 2 or 4 weeks. The secondary hypotheses were that there would be no significant difference in postoperative pain, motion, or strength. 40 trapeziectomies were reviewed. Two weeks' postoperative commissural immobilization was systematic. Patients were then divided in two groups. For the first 20 patients (group I), immobilization stopped at 2 weeks. For the next 20 patients (group II) it was replaced by a splint for further 2 weeks. We compared mean pre- and post-operative (10-20 weeks) function (QuickDASH score), pain (visual analog scale - VAS), thumb opposition (Kapandji score) and strength (palmar pinch test) between the two groups. There was no significant difference between groups in postoperative values or in pre- to post-operative progression. The main hypothesis was confirmed: there was no significant difference in the postoperative function whether the immobilization was for 2 or 4 weeks. The secondary hypotheses regarding postoperative pain, motion and strength were also confirmed.
