Abstract
Periprosthetic fractures (PPF) of the lower extremity are increasing as the population ages, as the number of joint replacement increases, and patients remain active. The management of PPFs is challenging because of implant and cement obstruction within the bone, poor bone quality, and limited availability of bone stock for screw purchase. Historically, they have been associated with high rates of nonunion, infection, and fixation failure. Minimally invasive osteosynthesis (MIO) has reduced complications and improved union rates compared to conventional open plating of fractures. This paper reviews the principles of treatment, implant choices, and technical challenges of MIO for PPF in the lower extremity. In recent series, PPF for the lower extremity has shown reduced complication rates, improved union, and early mobilization compared prior open treatment. MIO for PPF is technically challenging but promising method of treatment for PPF.
