The Primoris® femoral stem was designed to preserve bone and maintain normal stress to the proximal femur, thereby minimizing stress-shielding. The implant is anchored in the femoral neck and metaphysis without diaphysial involvement and differs from other neck prothesis by: a) Elliptical shape to fit the inner neck dimensions. b) On top of Ti– porous-coating electrochemically deposited hydroxy apatite (Bonemaster®) c) The surgical technique aims to enhance initial implant stability by compaction of neck and metaphyseal cancellous bone. As part of stepwise introduction to monitor bone remodeling, RSA data and clinical results.Introduction
