In contradiction to the traditional Hip replacement surgery in hip resurfacing, the femoral head is not removed, but is instead trimmed and capped with a smooth metal covering. The damaged bone and cartilage within the socket is removed and replaced with a metal shell, just as in a traditional total hip replacement. A hip resurfacing operation typically lasts between 1 1/2 and 3 hours. Your surgeon will make an incision in your thigh in order to reach the hip joint. The femoral head is then dislocated out of the socket. Next, the head is trimmed with specially designed power instruments. A metal cap is cemented over the prepared femoral head. The cartilage that lines the socket is removed with a power tool called a reamer. A metal cup is then pushed into the socket and held in place by friction between the bone and the metal. Once the cup is in place, the femoral head is relocated back into the socket and the incision is closed.
Decreased risk of hip dislocation.
Hip resurfacings may be easier to revise as the components used in hip replacements and hip resurfacings are mechanical parts which can wear out or loosen over time.
More normal walking pattern and adjustment with daily routine.
