Fracture around a loose femoral component with good bone stock

These fractures (classified by UCPF as V.3-B2) occur when the femoral component has loosened either at the time of injury or because of preexisting osteolysis. Therefore, surgeons need to consider if a V.3-B1 fracture should in fact be classified as V.3-B2.

Commonly these occur following a simple fall from standing height.

Occasionally, more active patients might sustain a high energy fracture.

• Pain
• Swelling
• Deformity
• Preceding pain or disfunction

Plain X-rays remain the first line of investigation.

CT Scan can help to assess possible fracture extension to the implant interface.
