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 · 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.
In the case of bipolar hemiarthroplasty, the procedure involves replacing the damaged femoral head with a prosthetic component with a two-part design: an inner head and an outer cup. This design allows the head to swivel within the outer cup, which helps reduce wear and tear on the new joint.
The difference between unipolar and bipolar hemiarthroplasty, two surgical approaches for hip joint conditions. Learn about the components replaced, movement mechanisms, surgical indications.
Bipolar hemiarthroplasty of the hip is a routinely done procedure in the elderly with neck of femur fractures. An uncommon yet widely recognized complication is the dislocation of...
10 lis 2020 · Bipolar prostheses do function as originally intended during gait, but movement primarily occurs at the outer bearing during other examinations. The motion patterns of bipolar prostheses change with the increase in acetabular wear.
15 gru 2021 · Predicted benefits of bipolar prosthesis include less acetabular wear, possibly less groin pain and ease of conversion of modular bipolar to a total hip replacement (THR) [14-17]. The theoretical advantage of a bipolar prosthesis is due to movement within the implant rather than between the prosthesis head and the acetabulum, which results in ...
