This study evaluated 45 active flexor tendon implants in scarred digits, showing significant improvement in total active motion (TAM). The research indicates the potential for permanent tendon prostheses in hand surgery.

Area of Science:

  • Orthopedic Surgery
  • Biomaterials Science
  • Reconstructive Surgery

Background:

  • Scarred flexor tendon beds present a significant challenge in hand reconstruction.
  • Previous methods often resulted in limited functional recovery.
  • The development of active implants aims to restore digital motion.

Purpose of the Study:

  • To evaluate the efficacy and safety of a novel active flexor tendon implant.
  • To assess functional outcomes, including total active motion (TAM), after implant placement.
  • To determine the feasibility of a permanent flexor tendon prosthesis.

Main Methods:

  • Forty-five active flexor tendon implants (silicone rubber with Dacron core) were placed in scarred digits (II-V).
  • Implant modifications were implemented during the study period to enhance performance.

  • Functional outcomes were assessed by measuring total active motion (TAM) and using the Boyes grade classification.

    • Main Results:

    • Stage I (implant functioning): Average TAM improvement of 72 degrees in digits previously classified as Boyes grade 5 (salvage).
    • Complication rate during Stage I was 11% (5/45).
    • Stage II (tendon autograft): 27 digits showed an average TAM improvement of 62 degrees, with 70% achieving Boyes grade 5.

    Conclusions:

    • Active flexor tendon implants are feasible for restoring motion in scarred tendon beds.
    • Implant modifications improved reliability and longevity.
    • The study suggests the potential for a permanent flexor tendon prosthesis in hand surgery.
