Abstract
In patients with hypoplastic hip joints, hip joint prostheses with relatively thin and narrow shank blades must be used. For this reason, due to the torque effect of the force acting on the joint head, the danger exists that deformations of the shank blades may occur. This danger is counteracted in that the collar type projection forming the transition between the shank and the prosthesis neck extends in a direction parallel to the prosthesis neck, preferably in a prolongation of the lower edge of the prosthesis neck.
