Abstract
The present invention provides a fused femoral stem system, including a curved short handle, a fixing mechanism and a femoral head prosthesis, one end of the curved short handle is provided with a conical connector, the conical connector is cooperatively connected with a conical connecting hole of the femoral head prosthesis, the other end of the curved short handle is inserted from the osteotomy surface of the femoral neck and stretches to the position of a medullary cavity below a small trochanter, and the curved short handle is connected and fixed with a large trochanter through the fixing mechanism. The present invention has the beneficial effects that, after the growing-in osseointegration with the sclerotin surrounding the proximal bone bed of the host after the surgery of the whole system, the mechanical influence on the retained femoral neck and the sclerotin in the vicinity of the large and small trochanters is substantially similar to the biomechanical state prior to the surgery.
