A member asked:
Is a hip hemi arthroplasty the same thing as a total hip replacement?
4 doctors weighed in across 3 answers
No: A hemi hip arthroplasty is a partial replacement where only the ball part is replaced with an artificial ball that is attached with a stem into the femur. The cup side of the hip joint is not replaced. In a total hip replacement an artificial acetabular cup is placed and secured into the socket and a ball is placed into the femur.

No: In a total hip replacement, both the ball portion and the socket portion of the hip are replaced. This is typically performed for arthritis. In a hemiarthroplasty, only the ball portion is replaced. This surgery is usually done for a hip fracture.

No: A hip hemiarthroplasty does not include lining the socket with metal and a new bearing. It only replaces the femoral head. A total hip does both.
