The hip joint is also known as a ball and socket joint, where the ball (femoral head) of the thigh bone fits into the socket (acetabulum) of the pelvis bone.
Damage to the hip bones can be treated by hip resurfacing, which is a surgical procedure in which the damaged parts of the femoral head are trimmed, and the socket is removed and replaced with metal caps.
Hip resurfacing is an alternative to total hip replacement surgery where both the ball and socket of the hip joint are completely removed and replaced with plastic, metal, or ceramic prosthetics.
Advantages of hip resurfacing.
The advantages of hip resurfacing over total hip replacement include:
- Easier to revise: Components used in both procedures usually wear out, loosen or fail after a period of 10 to 20 years, requiring revision surgery. As hip resurfacing involves less removal of bone, the revision surgery should be easier to perform.
- Lower risk of hip dislocation: As the ball size in hip resurfacing is larger and closer to the normal size, the risk of hip dislocation is less.
- More natural walking pattern
- Greater range of hip motion
