Control of independent digital flexion and extension has remained an elusive goal
in myoelectric prosthetics for upper extremity amputees. We first performed a cadaver
study to determine the feasibility of transferring the interossei muscles for each
digit to the dorsum of the hand without damaging the neurovascular pedicles. Once
this capability was ensured, a clinical case was performed transferring the interossei
of the middle and ring fingers to the dorsum of the hand where they could serve as
a myoelectric signal for a partial hand amputee to allow individual digital control
with a myoelectric prosthesis. Before surgery, it was impossible to detect an independent
signal for each interossei; however, after the surgery, signals were reliably detected,
which allowed these muscles to serve as myosites for finger flexion using a myoelectric
prosthesis and move each digit independently. This concept of salvaging innervated
and perfused muscles from an amputated part and transferring them into the more proximal
and superficial portion of a salvaged limb has broad applications for improved myoelectric
prosthetic control.
