Big Femoral Head (MicroPort)

Multiple types of hip implants are available for different hip replacement approaches, types of patients, and surgeon preferences. Total hip replacement implants replace your arthritic or damaged hip joint eliminating bearing surfaces that are causing you pain. The head of the femur (thigh bone) is replaced by a metal stem with a ball on top. A metal cup is placed in the acetabulum (hip bone socket) and the ball is fitted into the cup creating a new hip joint. Hip Resurfacing implants consist of a reinforcing cap fitted to the upper end of the femur (thigh bone) and a cup inserted into the acetabulum (hip bone socket) similar to that used in a total hip replacement.
