14 sie 2024 · Bipolar hip replacement is a type of partial hip replacement where the femoral head (the ball) is replaced with a prosthetic implant. Unlike total hip replacement, which replaces both the ball and the socket, bipolar hip replacement involves only the femoral head.
13 lip 2024 · What is a Bipolar Hip Prosthesis? Imagine a ball and socket joint which is your hip joint. In a healthy hip, the ball (femoral head) at the top of the thighbone fits snugly into the socket (acetabulum) of the pelvis.
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.
3 sty 2019 · Treatment for femoral neck fractures can be successfully achieved through a Bipolar Hemiarthroplasty using Bipolar Hip Prosthesis. Hemiarthroplasty is a surgical procedure that replaces one half of the hip joint with a prosthetic, while leaving the other half intact.
21 lip 2024 · unipolar and a bipolar prosthesis for use in hemiarthroplasty. The theoretical decrease in articular cartilage wear and increased range of motion with the bipolar device are frequently cited as the benefits obtained by choosing a bipolar design. Most frequently, cost containment is cited as the primary indication for use of a unipolar device.
15 paź 2020 · Bipolar hemiarthroplasty implants have an intra-prosthetic articulation that decreases motion at the bone-prosthesis interface which has been shown to decrease acetabular erosion in both randomized controlled trials[4] and large registry data .
