Hip Replacement

Total Hip ReplacementOSTEOARTHRITIS – The leading cause of joint replacement

The hip joint can develop arthritis over time, leading to a complete wear of the articular cartilage. When this point has been reached in the development of the disease, a total hip replacement is necessary to relieve hip pain and restore function by replacing the worn cartilage with an artificial bearing on both the pelvis and the femoral head.

Whenever the cartilage on the pelvic side is preserved (i.e. after a femoral neck fracture that cannot be repaired, for example) a hemiarthroplasty can be performed, in which the head of the femur is replaced but articulates with the native acetabular (pelvic) cartilage instead of an artificial bearing material as in a total hip replacement.

TOTAL HIP REPLACEMENT

Total Hip Replacement has been one of the most successful surgical procedures from the last century and remains the gold standard for the treatment of hips with arthritis. It starts with the insertion of a stem into the femoral medullary canal. A femoral head is mated with the neck of the stem and articulates with the acetabular component fixed to the pelvic bone.

Several bearing materials are suitable for total hip replacements and all combinations of a metal or ceramic head articulating with polyethylene, metal, or ceramic liners are possible. Your surgeon will determine which bearing couple is preferable based on multiple pre-and post-operative factors.
