Abstract
A hip implant comprises an acetabular cup to be inserted into an acetabulum of a pelvis, together with a femoral head and neck portion and a main body shaft to be inserted into the femoral neck and proximal femoral shaft. The femoral head and acetabular cup form a smooth spherical-surface joint. The femoral head on a femoral head base is attached to a femoral neck rod, which has a tapered end that engages in a hole through the main body shaft, i.e. the main body shaft has a diagonal hole therethrough located at the center line of the neck of the femur to receive the tapered end at a specified angle that aligns with center line of the neck. A secured lock mechanism, insertable into the main body shaft above the diagonal hole, can be screwed down to compressively engage the tapered end of the femoral neck rod. The diagonal hole (and matching tapered end of the femoral neck) can have an overlapping two-circle cross-section, can have a specified taper angle, and a choice of incline to match a patient's femoral angle between the neck and shaft. The tapered neck rod can have wedge-shaped locking surface features to provide even more stability.
