Abstract: A total hip femoral prosthesis provides a shortened neck and high porous coating level. Additionally, a means for strengthening the neck may be incorporated to increase stress transfer to the native bone. A method for reducing potential impingement that results from a high neck resection level includes cutting chamfered surfaces into the bone surrounding the proximal end of the implant. Instrumentation and methods of creating chamfered cuts are disclosed.

Abstract: A section of the implant is treated successively and separately with three different acids—hydrofluoric, sulphuric and hydrochloric acid—to create evenly distributed peaks on the surface and sufficient surface area. Plasma rich in growth factors is then applied to said surface.
