What is a partial hip replacement?

A partial hip replacement, also known as a hemiarthroplasty, involves replacing only the femoral head (top portion of the thigh bone) with an artificial implant. This procedure is typically performed in cases where the femoral head has been damaged or affected by conditions such as arthritis, fractures, or avascular necrosis (a condition where the blood supply to the bone is compromised).

In contrast to a total hip replacement, where both the femoral head and the socket of the pelvis (acetabulum) are replaced, a partial hip replacement involves a smaller incision and less bone removal. The recovery time and rehabilitation period may also be shorter for a partial hip replacement.

However, a partial hip replacement may not be suitable for all patients. Factors such as age, overall health, and the extent of damage to the joint may need to be considered before deciding on the best treatment option. Your doctor will discuss the risks, benefits, and alternatives to a partial hip replacement with you to determine the most appropriate treatment plan.
