A hip prosthesis comprising a hollow intramedullary stem with a tapered, closed inner end for insertion along the medulla of the femur, a brace segment on the outer end of the stem for engaging the stump of the femoral neck, a spherical ball on the brace segment, and a lag screw for slidable insertion through a passage in the brace segment into the screw-threaded interior of the stem. The stem has longitudinal slots through which the screw teeth of the lag screw project to engage cancellous bone.
