Tóm tắt

Background: Flexor tendon injuries in the hand are categorized into five zones, each requiring specific surgical repair techniques. Flexor digitorum profundus (FDP) tendon injuries in zone II of the hand present a significant challenge due to the complex anatomy and the risk of adhesion formation. Optimal management remains a subject of ongoing debate, with primary repair often favored for its potential to restore function. This study evaluates the early outcomes of primary repair for FDP tendon injuries in zone II. Objectives: To assess the early outcomes of primary flexor digitorum profundus tendon repair in zone II of the hand. Materials and methods: A prospective cross-sectional study was conducted on 32 patients (comprising 51 fingers) with zone II flexor digitorum profundus tendon injuries who underwent primary tendon repair at Can Tho Central General Hospital. Results: The results were observed in 32 patients (29 males, 3 females), with an average age of 31.31±8.59. Left-hand injuries accounted for the majority, representing 62.5%. There were 88.2% patients, with injuries affecting both the FDP and FDS (flexor digitorum superficialis) tendons. First phase surgical wound healing rate was 96.9%, tendon re-rupture rate was 6.3%, and there were no report of bleeding or suture exposure. Strickland criteria evaluation at 6 weeks showed 21.6% excellent, 49% good, 19.6% fair, and 9.8% poor outcomes. Conclusion: The surgical intervention and rehabilitation regimen for FDP tendon injuries in zone II are considered safe and produce a functionally acceptable outcome.
