  • Patent number: 9610084
    Abstract: A hip replacement method in which includes making an anterior incision and a lateral incision proximate the hip joint. The method next includes preparing a femoral passage directed along an axis of the femoral neck of the femur. An acetabulum reamer coupled to a femoral elongate element installed in the femoral passage is used to ream the acetabulum. The femoral head is prepared using a tool coupled to a femoral elongate element installed in the femoral passage. An acetabular prosthesis is then installed using a femoral elongate element installed in the femoral passage. A femoral prosthesis is installed using a femoral elongate element installed in the femoral passage. All of the foregoing steps are performed without dislocating the hip joint.
