ABSTRACT
PURPOSE: The purpose of this study was to present the outcomes of wide-awake flexor tendon repairs in zones 1 and 2 in a major hand trauma referral center. METHODS: Zone 1 and zone 2 wide-awake flexor tendon repairs performed between August 2018 and March 2020 were analyzed retrospectively. Outcomes were assessed by the original Strickland-Glogovac criteria for fingers and Buck-Gramcko scoring system for thumbs. Further descriptive analysis of the groups according to potential negative factors, such as injury mechanism, concomitant neurovascular injury, and the extent of injury in zone 2, were performed. RESULTS: A total of 94 tendons were repaired in 67 digits (58 fingers, 9 thumbs) of the 61 patients included in the study. Satisfactory results were achieved in 89.6% of the fingers and 77.8% of the thumbs. Intraoperative gapping was corrected after active digital extension-flexion test in 1 patient. Rupture was seen in 1 patient for a rate of 1.5%. The tenolysis indication rate was 5.1% for fingers and 11.1% for thumbs. CONCLUSIONS: In our series, functional outcome scores, tenolysis, and rupture rates remained similar with findings in the literature. The outcome of a flexor tendon repair is influenced by many factors that cannot be controlled intraoperatively. To assess the effect of performing the repair in a wide-awake setting on the outcome, clinical trials with large patient groups are needed. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
