Osseointegration is an innovative and revolutionary technology for individuals who have undergone upper or lower limb amputation, offering an innovative solution for patients experiencing poor socket-limb fit. Its purpose is to restore the mechanical axis of the limb to pre-amputation conditions.
The osseointegration implant rigidly attaches to the limb, eliminating unwanted movement, minimizing friction, and providing patients with increased freedom and comfort.
Osseointegration is performed during one or two separate procedures, depending on the patient’s individual circumstances. Specialized tools are used to prepare the bone channel for implant placement, which is then firmly pressed into position. This initial stability allows for earlier commencement of physiotherapy. Unnecessary soft tissues and fat are removed during the procedure to minimize the distance between the bone and the skin and reduce the risk of complications. Muscle groups are positioned to function correctly within the leg, while the fascial layer of the soft tissue closely approximates the bone. Subsequently, a circular skin opening is created at the base of the stump, above the tip of the implant. Through this opening, an adapter is connected to the implant, enabling the external attachment of remaining components and the prosthetic limb.
This technology originated in the 1990s and became possible through close collaboration between physicians and engineers, all with the aim of helping patients regain pain-free mobility.
Today, technology continues to evolve. Surface coatings are embedded with antibacterial nanoparticles, and fully customizable 3D-printed implants further enhance clinical research outcomes and reduce complications.
Technological advancements have also made osseointegration applicable to amputations below the elbow and below the knee, as well as finger amputations.
Professor Munjed Al Muderis, an Australian orthopedic surgeon, is the creator of osseointegration. To date, he has successfully performed over 700 procedures. While primarily operating in Australia, his collaboration with the Paley European Institute now allows European patients to benefit from this procedure.
