20080200995Percutaneous implant for limb salvage - A percutaneous implant device is biologically attached to bone and soft tissue of a broken limb or amputated limb without longitudinal or lateral movement. Bone and soft tissue in-growth are promoted. The percutaneous implant device has a bio-compatible metal alloy stem member, having an integral tapered fluted section designed to fit into a taper reamed bone canal. A precisely dimensioned cylindrical central core cooperates with a suture ring and an external extension member, facilitating attachment of the percutaneous implant device to a hand or foot prosthesis. A porous metal outer body having a female taper at one end and the capacity to promote growth of bone and soft tissue, is press fitted on the central core contacting suture ring. The assembled implant is inserted into a taper reamed bone cavity until the male taper-reamed bone free end contacts the female taper. Soft skin is extended over the outer surface of the porous metal outer body and the surrounding suture ring.08-21-2008
