Functional outcome in patients with zone V flexor tendon injuries

Introduction Zone V flexor tendon injuries may involve major nerves and arteries as well as the wrist and finger flexors. Although these injuries are not infrequent, few studies have reported functional outcomes. The purpose of this study was to evaluate the functional outcome in patients with flexor tendon repairs in zone V.Materials and methods Eighteen patients with repaired zone V flexor tendon injuries were followed up for an average of 20 months. The postoperative rehabilitation program consisted of a combined regime of modified Kleinert and modified Duran techniques. Outcome parameters were hand function according to the Buck-Gramcko assessment system, grip and key pinch strength values, and return to work status.Results Functional results were excellent in 92.8% of the digits, good in 1.4%, and poor in 5.8%. Grip strength recovered to an average of 77% and pinch strength to 74% of the uninjured hand. Two tendon ruptures occurred in a patient, and tenolysis was required in 3 patients. Of 15 patients who were employed at the time of injury, 13 returned to their original occupations.Conclusion Satisfactory functional results can be obtained when proper surgical technique is coupled with careful postoperative management in patients with zone V flexor tendon injuries.
