Bipolar hemiarthroplasty is a surgical procedure used to treat hip fractures, particularly when the head of the femur is damaged. The term "hemiarthroplasty" refers to replacing half of the hip joint with a prosthetic.
Use a trial bipolar or unipolar head prosthesis on the definitive stem to confirm appropriate diameter and neck length. The latter affects leg length, soft-tissue tension, and hip stability. With the hip reduced, confirm the range of motion and stability.
This procedure replaces one half of the hip joint with a prosthetic while leaving the other half intact. For patients with arthritis in their remaining hip joint from having previously suffered a fracture, it's best to use a bipolar version with a head that swivels during movement.
