Hip replacement is a surgical procedure in which the hip joint is replaced by artificial implants. Hip replacement surgery can be performed as a total replacement or a hemi replacement (and a half).
Such joint replacement orthopedic surgery generally conducted to relieve arthritis pain or fix physical damage together as part of hip fracture treatment.
Total hip replacement (total hip arthroplasty) consists of replacing the acetabulum and the femoral head while hemiarthroplasty generally only replaces the femoral head.
Hip replacement is currently the most successful and reliable orthopedic operation with 97% of patients report improvement.
Total hip replacement is commonly used to treat joint failure caused by osteoarthritis.
Other indications include rheumatoid arthritis, avascular necrosis, traumatic arthritis, protrusio acetabuli, certain hip fractures, benign and malignant bone tumors, arthritis associated with Paget’s disease, ankylosing spondylitis and juvenile rheumatoid arthritis.
Purpose of the procedure is pain and improvement in hip function.
Hip replacement is usually considered only once other therapies, such as physical therapy and pain medications, have failed.
What Is A Total Hip Replacement?
A total hip replacement is a surgical procedure in which the diseased cartilage and bone surgery of the hip joint is replaced with artificial material. Normal hip joint is a ball and socket joints. The socket is a “cup-shaped” bone pelvis called the acetabulum. The ball is the head of the thigh bone (femur). Total hip joint replacement involves surgical removal of the diseased ball and socket and replace it with a metal (or ceramic) ball and stem inserted into the femur bone and an artificial plastic (or ceramic) cup socket. Metallic artificial ball and stem are called as the “prosthesis.” After inserting the prosthesis into the central core of the femur, it is fixed with bone cement called methylmethacrylate. Or, “cementless” prosthesis is used which has microscopic pores that allow bone ingrowth from the normal femur into the prosthesis stem. This “cementless” hip is felt has a longer duration and is considered especially for younger patients.
