22 cze 2022 · Bipolar hemiarthroplasty (BHA) is a surgical treatment for femoral neck fractures of the hip. An artificial joint with two bearings replaces the damaged joint. The bearings allow the head to...
13 lip 2024 · The bipolar prosthesis itself is a two-part implant. It has a metal stem that fits into the hollow shaft of the femur and a smooth, articulating head. However, the key difference from a standard hip replacement is that the head in a bipolar prosthesis has two articulating surfaces.
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.
14 sie 2024 · Bipolar hip replacement involves replacing the femoral head with a two-piece prosthesis that allows for dual mobility, whereas total hip replacement involves replacing both the acetabulum and the femoral head with single-piece components.
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.
15 paź 2020 · The main theoretical advantage of a bipolar femoral prosthesis is decreased acetabular cartilage erosion secondary to shared articulation within the dual-bearing system . This is in contrast to the fixed unipolar femoral prosthesis which articulates directly at the acetabular-implant interface.
During a hemiarthroplasty procedure, the damaged femoral head and neck are removed and replaced with a small spherical artificial ball (prosthetic) held in place by either cement or acrylic bone cement. Physical therapy is essential following this procedure to help restore movement and normal joint function.
