ABSTRACT

Introduction: Injuries to the extensor tendons in the hand are common in the daily practice of the orthopedic surgeon. Currently, the extensor zone I of the hand does not have a gold standard of treatment. Objective: To describe the functional results of the surgical repair, with a 1.3-mm anchor, of rupture of the extensor tendon in zone I of the hand and follow-up at six months post-surgical evolution. Material and methods: We included a retrospective cohort of patients subjected to tenorrhaphy with a 1.3-mm anchor (MICROFIX QUICKANCHOR Plus DePuy MitekTM Raynham, MA) of the extensor tendon in zone I of the hand with traumatic lesions and follow-up six months after surgery. The patients were evaluated from March 2013 to February 2017. The degrees of mobility, flexion and extension of the distal interphalangeal (DIP) joint were grouped into four categories: poor, fair, good and excellent. Results: We included 43 patients with extensor tendon rupture in zone I of the hand who were managed with tenorrhaphy with a 1.3-mm anchor. Extension of the DIP joint was good in 34 (79%) cases and was regular in 9 (21%); flexion was excellent in 23 (54%) cases and good in 15 (35%). Conclusion: Tenorrhaphy with a 1.3-mm anchor is a novel procedure that has been described for the first time for the management of extensor tendon rupture in zone I of the hand. The functional results of the DIP joint, six months after the procedure, were superior to those reported with conventional techniques.
