Toe transplantation to the forearm stump enabled a 100% accuracy rate in controlling a multi-freedom electronic artificial hand. This innovative technique offers a promising solution for improving prosthetic control and reducing errors.

Area of Science:

  • Medical Engineering
  • Reconstructive Surgery
  • Prosthetics

Background:

  • Forearm amputation presents significant challenges for restoring hand function.
  • Advanced electronic artificial hands offer potential but often face control accuracy issues.

Purpose of the Study:

  • To evaluate the efficacy of using a transplanted toe to control a multi-freedom electronic artificial hand.
  • To assess the functional outcomes and control accuracy of this reconstructive approach.

Main Methods:

  • A 19-year-old female patient with a forearm amputation underwent transplantation of her second toe to the forearm stump.
  • Post-transplantation, the patient underwent comprehensive rehabilitation focusing on weight bearing, sensory feedback, stability, and digit control.
  • The reconstructed digit was used to control a multi-dimension-freedom electronic artificial hand.

Main Results:

  • The transplanted toe demonstrated successful survival and integration.
  • Following rehabilitation, the reconstructed digit exhibited good function.
  • The electronic artificial hand achieved a 100% accuracy rate in performance tests.

Conclusions:

  • Toe transplantation to the forearm stump is a viable method for controlling advanced electronic artificial hands.
  • This technique significantly improves control accuracy, achieving 100% in this case.
  • It presents a valuable pathway for enhancing prosthetic control and minimizing false actions in multi-freedom artificial hands.
