Is Osseointegration Surgery an Alternative for You?

At Kelsey Prosthetics and Orthotics, we are trained in all advanced technology and medical procedures that assist amputees in mobility and function. One such surgical procedure is osseointegration, in which a titanium rod is implanted in the bone of the residual limb, allowing a prosthesis to be directly connected to the body and therefore eliminating the need for a socket.

Technically called Osseoanchored Prostheses for the Rehabilitation of Amputees (OPRA) Implant System, it was initially designed for adults who have a transfemoral amputation. However, it has been extended to transtibial and upper limb amputees.

The OPRA Implant System is installed in two surgical procedures. In the first procedure, a cylinder-shaped fixture is implanted into the central canal of the bone. Approximately three months later, after tissue has grown to anchor the fixture and the skin tissue has healed, a second surgery is performed to attach an abutment outside of the skin. Then, the OPRA Axor connection device is attached to the abutment. It acts as a safety connection between the implant and the prosthesis, designed to prevent damage if the implant is overloaded, such as in high bending and/or rotational moments. If that occurs, the Axor twists the prosthesis to protect the implant from damage.

Studies indicate that osseointegration has positive outcomes including increased use of a prosthesis, more stability in walking and standing, ability to walk longer distances, comfort when seated and decreased skin problems. Plus, donning and doffing the prosthesis is quicker and easier.

Amputees who are interested in the surgery are advised to thoroughly discuss the benefits and risks with their health care provider.
