Fracture around a loose femoral component with poor bone stock
General considerations
These fractures occur when osteolysis has caused the loss of bone stock and loosening of the femoral component.
They are classified by UCPF as V.3-B3.
Etiology
V.3-B3 fractures often occur with minimal or no trauma.
Clinical signs
- Preexisting swelling, pain, and dysfunction
- New pain, swelling, and deformity after injury
- History of possible infection
Imaging
Plain X-rays remain the first line of investigation.
CT Scan is required to assess possible fracture extension to the implant interface.
