The most common approach for total hip ahroplasty is: (A) Anterolateral, (B) Posterolateral, (C) Anteromedial, (D) Posteromedial
Answer is B. Total hip replacement is an operation where both, the acetabulum and the head of the femur are replaced with aificial components. For the acetabulum, a cup made of high-density polyethene is used, and for the head, a specially designed prosthesis made of metal alloy (cobalt-chromium alloy) is used. The most common approach for total hip ahroplasty is the posterolateral approach. Ref: Maheshwari 6e pg 338.
