These fractures are classified by UCPF as V.4-B1.

Stable component, good bone quality


Simple fall.

Clinical signs

  • Pain

Plain X-rays remain the first line of investigation.

CT scan can be used to assess the size and position of fragments, implant stability, and bone stock.

Comparison with previous X-rays is useful.
