The Starfish Procedure enables myoelectric prosthetic digits for partial hand amputations. This surgical technique allows intuitive control of prosthetic fingers with minimal signal interference.

Area of Science:

Reconstructive surgery
Biomedical engineering
Prosthetics

Background:

Partial hand amputations pose challenges for restoring prehensile function.
Existing myoelectric prosthetics often lack intuitive individual digit control.
Minimizing myoelectric cross-talk is crucial for effective prosthetic function.

Purpose of the Study:

To present the Starfish Procedure for creating muscle transfers in partial hand amputations.
To enable the generation of intuitively controlled electromyographic signals for prosthetic digits.
To achieve individual digital control with minimal myoelectric cross-talk.

Main Methods:

The Starfish Procedure involves muscle transfers to create multiple sources of myoelectric signals.
Preoperative planning is essential for optimizing signal generation.

Keywords:

Amputation Electromyographic signal Interossei muscle transfer Myoelectric control Partial hand amputation Prosthesis Ray resection

The procedure does not require microsurgery, enhancing its applicability.

Main Results:

The Starfish Procedure facilitates the generation of high-quality myoelectric signals.
It allows for intuitive, individual control of prosthetic digits.
Minimal myoelectric cross-talk is achieved, improving prosthetic function.

Conclusions:

The Starfish Procedure is a viable surgical option for partial hand amputations requiring myoelectric prosthetic digits.
It offers a method for achieving intuitive and precise prosthetic control.
The technique's applicability is broad due to its non-microsurgical nature.
