FUNCTIONAL EVALUATION OF DIGITS AFTER FLEXOR TENDON PRIMARY ZONE II REPAIR

Abstract

Aim: The purpose of this prospective study was an evaluation of results in primary treatment of flexor tendon laceration in zone II. Special emphasis has been given to the postoperative rehabilitation program.

Material and Methods: Nineteen patients, (23 fingers), with laceration of the flexor tendons in zone II were treated operatively. Twelve males and seven females were included in the study. Their mean age was 28 (range, 16 to 50) years. In twelve cases a concomitant laceration of the digital nerve was present, hi all cases primary repair of all injured tendons and nerves was performed and a dorsal splint was applied. On third to fifth postoperative day an exercise program commenced involving passive flexion-active extension of the injured fingers. Eighteen (22 fingers) of 19 patients completed the follow-up.

Results: The results were estimated according to Strickland’s original classification system. In fifteen cases the result was excellent, in five good, and in two fair. Conclusions: After primary repair of injured flexor tendons, close follow-up, early protected motion and unrestricted motion of the interphalangeal joints affers the best chance of restoring optimal function to the hand.
