description Austin Moore Overview

Austin Moore was an American orthopedic surgeon whose name is attached to the Austin Moore prosthesis, an early metal implant used to replace the femoral head. Introduced in the early 1950s, the device is a one-piece, or unipolar, hemiarthroplasty prosthesis designed for insertion into the femur. It became widely associated with surgical treatment of displaced femoral-neck fractures, particularly in older patients.

help Austin Moore FAQ

What is an Austin Moore prosthesis used to replace?

It replaces the femoral head and neck on the hip side of the joint while leaving the patient's acetabulum intact. This makes it a hemiarthroplasty implant rather than a total hip replacement.

Why was the Austin Moore prosthesis historically important?

Developed by orthopedic surgeon Austin T. Moore, it became one of the first widely used metal femoral-head prostheses. Its design helped establish hip hemiarthroplasty as a treatment for displaced fractures of the femoral neck.

What is distinctive about the stem of an Austin Moore implant?

The classic implant has openings in its stem intended to permit bone ingrowth and anchorage. It is generally inserted without bone cement, unlike cemented designs such as the Thompson prosthesis.

Is an Austin Moore replacement the same as a modern total hip replacement?

No. A total hip replacement substitutes both the femoral component and the acetabular socket, while an Austin Moore hemiarthroplasty replaces only the femoral side.
