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...
10 lis 2020 · Bipolar prostheses are designed to have two articulations. The inner, low friction bearing is composed of a metal inner head and a polyethylene liner, while the outer bearing is composed of a metal outer head and an acetabulum.
13 lip 2024 · Femoral neck fractures. In certain cases of fractured femur necks, especially in younger, active patients, a bipolar prosthesis can offer a good balance of stability and mobility. The additional articulation within the bearing allows for some movement, which can be beneficial for long-term function. Avascular necrosis (AVN)
15 gru 2021 · The purpose of this study was to compare the functional and radiological outcome of cemented unipolar vs modular bipolar hemiarthroplasty in displaced femoral neck fracture in elderly patient population. Methods: It is a prospective randomized study, with 44 patients in each group.
Symptoms of Hip Fractures: Severe Hip Pain: Especially in the groin or outer thigh. Inability to Move: Difficulty moving the leg or bearing weight. Swelling and Bruising: Around the hip or thigh.
