Thumb reconstruction using toe-to-thumb transfers restored function and appearance in 11 of 12 patients. This innovative technique preserves foot function and aesthetics, offering a viable solution for thumb amputation.

Area of Science:

  • Microsurgery
  • Orthopedic Surgery
  • Reconstructive Surgery

Background:

  • Thumb amputation significantly impacts hand function and quality of life.
  • Restoring thumb function requires complex reconstructive techniques.

Purpose of the Study:

  • To evaluate the efficacy of a dual-flap toe-to-thumb transfer for thumb reconstruction.
  • To assess functional outcomes, aesthetic results, and donor site morbidity.

Main Methods:

  • Reconstruction of 12 amputated thumbs using combined great toe neurovascular cutaneous and second toe osteotendinous flaps.
  • Both flaps were based on a single vascular pedicle.

Main Results:

  • Successful reconstruction in 11 out of 12 cases (92% success rate).

  • Restored metacarpophalangeal joint mobility (10-50 degrees) and interphalangeal joint mobility (10-30 degrees).
  • Achieved functional opposition and key pinch, with thumb shape and volume similar to the normal thumb. Donor great toes were preserved with normal gait in all patients.

    • Conclusions:

    • Toe-to-thumb transfer is an effective method for thumb reconstruction, restoring function and aesthetics.
    • The technique preserves donor foot function and appearance, making it suitable for children.
    • Potential disadvantages include a lengthy surgical procedure and a notable rate of major complications (17%).
