Single-Stage Flexor Tendon Graft Reconstruction of the Fifth Finger: A Case Report

Abstract: Flexor tendon injuries, particularly in zone II of the hand, represent a surgical challenge. Secondary reconstruction following failed primary repair often involves a two-stage tendon graft. However, in selected cases, a single-stage reconstruction can yield favorable outcomes. We present the case of a 20-year-old woman with a history of failed primary repair of the flexor digitorum superficialis (FDS) and flexor digitorum profundus (FDP) tendons of the fifth finger. She was successfully treated with a single-stage tendon graft using the palmaris longus tendon. The postoperative course included 4 weeks of immobilization followed by 20 sessions of passive and active rehabilitation. At 3 months, she recovered satisfactory flexion with good functional outcomes. This case supports the role of single-stage grafting in well-selected patients.
