Complex extensor tendon injuries: early active motion following single-stage reconstruction.

Abstract

This study presents a retrospective evaluation of patients managed with single-stage repair following complex extensor tendon injuries. Over a 2-year period, 21 extensor tendons were reconstructed in 18 patients with complex hand injuries in zones V-VII. All eight patients needed soft tissue cover. Active mobilisation was started in the first week. Total active motion (TAM) at 4 weeks was a mean of 159 degrees (SD 21.57) and at 6 weeks it was 202.6 degrees (SD 13.26). Average TAM at 8 weeks was 223.8 degrees (SD 16.46) and 249.5 degrees (SD 14.38) at 12 weeks. Grip strength at 12 weeks and 6 months was around 75% and 90% of the contralateral normal hand in most of the patients. Single-stage reconstruction of complex extensor tendon injuries seems to reduce morbidity in terms of hospitalisation, and reduced cost of treatment. It also helps to achieve better functional outcome in the early postoperative period.
