Pediatric flexor tendon repair yields excellent results, with primary suture and controlled mobilization leading to better outcomes than in adults. Repairing both flexor digitorum superficialis (FDS) and flexor digitorum profundus (FDP) tendons is recommended for optimal hand function in children.

Area of Science:

  • Pediatric Orthopedics
  • Hand Surgery
  • Reconstructive Surgery

Background:

  • Flexor tendon injuries in children present unique challenges compared to adults.
  • Early and effective surgical intervention is crucial for restoring hand function.
  • Pediatric patients exhibit distinct healing characteristics influencing surgical outcomes.

Purpose of the Study:

  • To evaluate the efficacy of primary suture and controlled mobilization for pediatric flexor tendon injuries.
  • To compare outcomes of repairing both flexor digitorum superficialis (FDS) and flexor digitorum profundus (FDP) tendons versus FDP alone.
  • To assess the long-term functional recovery and complication rates in children undergoing flexor tendon repair.

Main Methods:

  • Retrospective review of 38 children (mean age 6.7 years) treated between 1985-1992.

  • Surgical repair via primary suture followed by controlled mobilization.
  • Classification of outcomes using Lister's criteria.
  • Analysis of injury zones, specifically zone 2, and associated nerve injuries.

    • Main Results:

    • 82% of patients achieved excellent or good results based on Lister's criteria.
    • Injuries most commonly affected the little finger (23 patients) and occurred in zone 2 (60%).
    • Repair of both FDS and FDP tendons yielded superior outcomes compared to FDP repair alone, even in zone 2.

    Conclusions:

    • Primary suture and controlled mobilization provide excellent outcomes for pediatric flexor tendon injuries.
    • Repairing both FDS and FDP tendons is recommended for optimal functional recovery in children.
    • Children demonstrate superior healing and pliability, leading to better results and fewer complications like adhesions requiring tenolysis compared to adults.
