These fractures occur proximal to the femoral component. It is important to evaluate prosthesis stability to determine if fixation is appropriate.
Intramedullary nailing is often desirable and so information about the presence of an open or closed box is needed.
These fractures are classified by UCPF as V.3-C.
Commonly these occur following a simple fall from standing height.
Occasionally, more active patients might sustain a high energy fracture.
Similar to other femoral shaft or distal femur fractures.
Plain X-rays remain the first line of investigation.
CT Scan is rarely helpful. It may be used to assess possible loosening at the implant interface or occult fracture extension.
