Fractures périprothétiques [Periprosthetic fractures]

A periprosthetic fracture is a fracture around or in proximity of a prosthetic implant. As more and more prostheses are implanted, the incidence of periprosthetic fractures also increases. Several risk factors have been outlined, some due to the patient, and some due to the implant itself. Key points in diagnosis are the case history and the imaging, as they allow the distinction between a well-fixed and a loose prosthesis. Correct classification is crucial for the treatment choice, which can be non-operative or consist in an osteosynthesis or in a revision arthroplasty, depending on the patient's general medical condition and the local status.
