Periprosthetic fractures of the femur (lower extremity)

A 66-year-old female tripped and fell while getting out of a car. Her past surgical history included a left Total Knee Replacement (TKR) performed six months earlier.

Radiographs revealed a left-sided comminuted periprosthetic femur fracture proximal to the femoral component. A CT Scan was performed and the femoral component was determined to be stable. Through a minimally invasive technique with indirect reduction, the fracture was reduced and fixed using a LISS locking plate and screws.

She returned for regular follow-up and healed uneventfully and at 2 years she presents with an excellent outcome including a healed periprosthetic femur fracture, resolution of pain, and a return to pre-injury activities.
