Attachment of a Myoelectric Prosthesis after Transulnar Osseointegration Implantation: A 2-Patient Case Study

Abstract

Case: This report discusses 2 successful cases of traumatic transulnar amputees who underwent osseointegration implantation. After surgery, a myoelectric prosthetic equipped with Coapt (Chicago, IL) recognition software was attached directly to the implant. Patients underwent training with pattern recognition software to learn to control the myoelectric prosthetic with the multiarticulating hand and wrist. Both implants osseointegrated without signs of loosening at the most recent follow-up of 18 months and 2 years, respectively. Prosthetic control gradually improved to allow activities of daily living. Conclusion: These cases demonstrate what can be achieved with interdisciplinary coordination between surgeons, prosthetists, and emerging technologies.
