Is Hemiarthroplasty Same as Hip Replacement?

Overview. A hemiarthroplasty is a surgical procedure that involves replacing half of the hip joint. Hemi means “half” and arthroplasty refers to “joint replacement.” Replacing the entire hip joint is called total hip replacement (THR). A hemiarthroplasty is generally used to treat a fractured hip.

What is the difference between a total hip replacement and a Hemiarthroplasty?

Comparing Surgical Options for Hip Fracture

Options include hemiarthroplasty, which involves replacing the femoral head with a prosthesis, or total hip arthroplasty, which involves replacement of both the femoral head and the acetabulum with prostheses.

Is a Hemiarthroplasty a partial hip replacement?

HonorHealth's orthopedic surgeons perform partial hip replacement, technically known as hemiarthroplasty, almost exclusively when the ball-like head of the thighbone (the femoral head) has been fractured or traumatically injured.
