ABSTRACT:
A hip joint prosthetic device having a support shank to be fitted into the medullary canal of the femur and which, in its proximal region, has a curvature in the AP plane with a center of curvature at its anterior that makes the shank more compatible to naturally existing conditions of the femur, permits a substantial increase in the shank thickness, reduces shank tendency to turn within the medullary canal, simplifies the prosthesis operating procedures and improves the association of the shank with the trochanter region of the femur.
