Hemiarthroplasty considerations

1. Surgical considerations

Unstable periprosthetic femur fractures can occur in patients with previous hemiarthroplasty. In this setting, the surgeon should follow the evaluation and treatment outlined in the management of hip periprosthetic femur fractures in the AO Surgery Reference.

In the low-demand patients, following revision of the stem and appropriate fixation of the femur fracture, another hemiarthroplasty component (bipolar or unipolar) can be used.

2. Indications for revision to total hip arthroplasty

  • Associated acetabular cartilage wear with preexisting clinical symptoms
  • Associated acetabular fracture

In these situations, the surgeon should consider inserting an acetabular cup following the surgical techniques recommended in the AO Surgery Reference.
