COMPARISON OF THE SURGICAL OUTCOMES FOR TRIGGER FINGER AND TRIGGER THUMB: PRELIMINARY RESULTS

Abstract

We reviewed 110 trigger digits, treated surgically, to compare the outcomes of trigger finger and trigger thumb in terms of peri-operative characteristics and complications. The patients with trigger thumb complained mainly of pain on motion, while those with trigger finger complained of triggering or limited range of motion. Trigger fingers had a significantly longer duration before surgery than did trigger thumbs. Trigger fingers took significantly longer for the symptoms to subside. In our series, 64% of trigger fingers had a flexion contracture of the PIP joint more than three weeks after surgery. Our results suggest that the peri-operative characteristics and outcomes differ between trigger finger and thumb, and that the surgical outcome for trigger finger was poorer than that for trigger thumb, partly due to flexion contracture of the PIP joint.
