These fractures are similar to V.4-B2 fractures, but with more severe bone loss.
They are classified by UCPF as V.4-B3.
Fractures often occur with minimal or no trauma.
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.
Prior X-Ray is useful for comparison of implant position and bone loss.
