Flexor tendon graft through intact superficialis tendon

H H Stark, N P Zemel, J H Boyes

    The Journal of Hand Surgery
    |November 1, 1977
    PubMed
    Summary

    Free tendon grafts successfully reconstructed the flexor profundus mechanism in 25 fingers, with 20 patients achieving satisfactory functional outcomes. This surgical approach offers significant benefits for selected patients with finger injuries.

    Area of Science:

    • Orthopedic Surgery
    • Hand Surgery
    • Reconstructive Surgery

    Background:

    • Flexor profundus tendon injuries can lead to significant loss of finger function.
    • Previous surgical techniques for flexor profundus reconstruction have varied outcomes.
    • Free tendon grafts offer a potential solution for restoring flexor profundus function.

    Purpose of the Study:

    • To evaluate the efficacy of free tendon grafts in reconstructing the flexor profundus mechanism.
    • To assess functional outcomes based on specific criteria for satisfactory results.
    • To identify patient and injury characteristics that predict successful outcomes.

    Main Methods:

    • Retrospective review of 25 patients undergoing flexor profundus reconstruction with free tendon grafts over 14 years.

  • Graft placement involved passing through or alongside the intact superficialis tendon.
  • Outcomes were evaluated using defined criteria for finger flexion, distal joint flexion, and proximal interphalangeal/distal interphalangeal joint extension.

    • Main Results:

    • Twenty out of 25 patients (80%) achieved satisfactory functional results.
    • Satisfactory outcomes were defined by specific range of motion and flexion criteria.
    • Four patients had unsatisfactory results, and one remained unchanged.

    Conclusions:

    • Free tendon grafting is an effective method for reconstructing the flexor profundus mechanism.
    • Selected patients aged 10-21 with limber joints and minimal scarring can benefit significantly.
    • Adequate superficialis tendon function is crucial for optimal outcomes in this patient group.
