Percutaneous Osseointegrated Prostheses for Transfemoral Amputations.

The direct attachment of the osseointegrated prosthesis to the skeleton avoids the inherent problems of socket suspension. It also permits physiological weight bearing, improved range of motion in the proximal joint, and osseoperceptive sensor feedback, enabling better control of the artificial limb by amputees. This article describes the osseointegration program in Sweden based on the use of bone-anchored prostheses for transfemoral amputation rehabilitation. The authors discuss in detail the patient-centered evaluation, surgical technique, and postoperative rehabilitation protocol. The outcomes of a prospective study of transfemoral amputees using the bone-anchored prostheses are presented.
