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.
