Fracture around a stable femoral component with good bone stock

General considerations

These fractures occur when the femoral component remains well fixed and was functioning well prior to the injury.

These fractures are quite rare because the fracture pattern tends to either occur proximal to the femoral component (V.3-C type) or causes loosening of the femoral component (V.3-B2 type).

These fractures are classified by UCPF as V.3-B1.

Etiology

Commonly these occur following a simple fall from standing height.

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

Clinical signs

  • Pain
  • Swollen
  • Deformity

Imaging

Plain X-rays remain the first line of investigation.

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