<p>The present invention extends to a stemmed amputation implant. In some embodiments, a dual stemmed implant includes a base plate and two intramedullary rods extending from the proximal side of the base plate. The two intramedullary rods are configured for insertion into corresponding intramedullary bone canals reamed into remaining portions of amputated bones, such as, for example, a tibia and fibula or an ulna and radius. The position of the intramedullary rods relative to one another is configured to maintain appropriate separation between amputated bones when the first intramedullary rod and the second intramedullary rod are inserted into the amputated bones. In some embodiments, a hollow tube replaces one or more of the intramedullary rods. A hollow tube can be configured to cover the exterior of a bone, such as, for example, the fibula, when the bone is not stable enough for intramedullary fixation.</p> |
