Osseointegration allows for the direct attachment of an external prosthesis to the skeleton through the surgical implantation of intramedullary device.
Historically osseointegration was first introduced as a two-stage procedure. This approach involved implanting a press fit intramedullary component followed by a 6-8 week period of passive healing. After this time a second surgery was needed to create an opening in the skin or “stoma” as it is commonly called, insertion of dual cone and external components. After this, rehabilitation would be commenced.
Since 2014 A/Prof Al Muderis modified the surgical technique and developed a new implant design which facilitated the ability to perform single-stage surgery without compromising outcomes. This has resulted in eliminating the need for a second operation and the associated risks, improved soft tissue management, faster rehabilitation, earlier return to work and lower overall costs.
Osseointegration has the potential to:
A lot of patients ask if their reason for amputation will limit their suitability for osseointegration. The vast majority of our case cohort have undergone an amputation as a result of trauma. Following this, the second biggest cause of amputation has been due to infection, commonly an infected joint replacement. Cancer follows third, however we have to take caution that the site of amputation has not undergone radiation therapy as this will affect outcomes of osseointegration.
