Joshua C Rozell,1 Dimitri E Delagrammaticas,2 Ran Schwarzkopf1 1Department of Orthopaedic Surgery, NYU Langone Orthopaedic Hospital, New York, NY, USA; 2Central Coast Orthopedics, San Luis Obispo, CA, USACorrespondence: Ran SchwarzkopfNYU Langone Orthopaedic Hospital, 301 East 17th St, Suite 1402, New York, NY 10003, USATel [phone]Email [e-mail]: Interprosthetic femur fractures are a rare but serious complication following total hip and knee arthroplasty. Classification systems have focused not only on diagnosis but also on treatment algorithm. Critical to the evaluation of patients with these fractures are an assessment of fracture location, bone quality, and the presence of stemmed implants. The gold standard for fracture fixation is locked plating with bicortical and unicortical screws, supplemented with wires or cables as needed. For patients with compromised bone stock or insufficient bony area for fixation, allograft augmentation with struts or interprosthetic sleeves may be used. For fractures with severe bone loss, conversion to a megaprosthesis or total femur replacement may be warranted.Keywords: interprosthetic, total knee arthroplasty, total hip arthroplasty, revision, periprosthetic fracture
