Abstract
The femoral neck preserving hip implant includes a polymer femoral head molded onto a femoral head base, which is attached to a femoral neck rod to be inserted into the femoral neck of a patient. A metal acetabular cup is inserted into an acetabulum anatomy of a pelvis. The femoral head interfaces with the acetabular cup as a smooth plastic-to-metal spherical-surface joint. A main body shaft to be inserted into a femoral shaft has a diagonal hole therethrough located at a center line of the femur's neck to receive the femoral neck rod at a specified angle. A secured lock mechanism in the main body shaft above the diagonal hole is screwed down to compressively engage the femoral neck rod. Both the diagonal hole and the end of the femoral neck rod may have a slight taper. The femoral neck rod also has a radially outward extending flange that forms a contact feature that sits upon the resection plane of the femoral neck to stabilize against axial force loading.
