Abstract:
1. A prosthetic apparatus for total hip replacement, comprising: a prosthetic femoral head comprising a partially spherical head portion configured to fit rotatably within a prosthetic acetabular cup seated in an acetabulum, the prosthetic femoral head also comprising a neck engagement portion configured to fixedly join a prosthetic femoral neck; an intramedullary rod configured to be inserted within a femur such that at least a portion of a proximal end of the intramedullary rod is positioned within a trochanteric region of the femur and a distal end of the intramedullary rod is positioned deeper in the femur, the intramedullary rod including a lateral bore; and a prosthetic femoral neck having a head engagement end configured to fixedly join the neck engagement portion of the prosthetic femoral head, the prosthetic femoral neck comprising a taper, the prosthetic femoral neck configured to be advanced from a position along a side of a patient's body, through a side of the femur opposite the acetabulum, and through the lateral bore of the intramedullary rod, wherein the taper is configured to lock the prosthetic femoral neck such that the head engagement end of the prosthetic femoral neck fixedly joins the neck engagement portion of the prosthetic femoral head while a portion of the prosthetic femoral neck occupies the lateral bore; and a support sleeve adapted to be seated in the trochanteric region of the femur, the support sleeve including a rod bore and a neck passage, the rod bore configured to hold a portion of the proximal end of the intramedullary rod while the distal end of the intramedullary rod is positioned deeper in the femur such that the neck passage is aligned with the lateral bore of the intramedullary rod to accommodate advancement of the prosthetic femoral neck through both the neck passage and the lateral bore.
