A Rare Case of Open (Gustilo II) Periprosthetic Fracture (Vancouver B2) in a Polytraumatized Patient.

Periprosthetic femoral fracture is the third most frequent complication after total hip replacement (THR). It is mainly caused by low-energy trauma in the elderly. Open periprosthetic fractures are significantly rarer and are caused by high-energy trauma. Here we present a case of a 73-year-old man who sustained an open (Gustilo II) left periprosthetic femoral fracture with an unstable femoral component (Vancouver B2). After an early stabilization with a temporary external fixator, a single-stage revision using a tapered long femoral stem was performed. At the last follow-up (3.2 years), the patient was satisfied and walked without pain and aids, and the Harris Hip Score was 83.5. No signs of infection or osteolysis were present in the last radiographs.
