Tissue-sparing surgery: 25 years’ experience with femoral neck preserving hip arthroplasty

Abstract

Tissue-sparing surgery is a surgical strategy that aims to preserve, as much as possible, both bone and soft tissue, in order to minimize the invasiveness of the operation and the overall treatment aggression. This is achieved, in the field of hip replacement surgery, by conservation of the femoral neck through the use of “mini-prostheses” such as the Biodynamic and later the CFP. In this paper, we illustrate the biomechanical characteristics and structure of the CFP prosthesis and briefly describe our 25-year experience in conserving the femoral neck during hip replacement surgery. In particular, we report the results of 943 implants, demonstrating a high percentage of excellent results and good clinicoradiographic results (97%) with a survival rate of almost 100%.
