The QUATTRO Dual Mobility Cup.A Technical Revolution in Total Hip Arthroplasty:History and evolution of a French concept

摘要

Total hip arthroplasty (THA) consists of replacing a diseased hip with an artificial joint: the hip implant helps to relieve pain and improve a patient's mobility. Over the past 50 years, this procedure has become one of the most reliable in the fieldof orthopedic surgery and it has contributed to great improvement in the quality of life and activity level of older people[1].The Judet brothers tried first in 1950 to replace the femoral head with an acrylic polymer sphere fixed in the femoral shaft with a metal-reinforced stem[2]. But the "modern" hip prosthesis configuration was invented by Sir John Charnley in 1962: he combined a femoral stem with an acetabular cup, with both components fixed to bone thanks to acrylic bone cement [3-5].
