Periprosthetic Fractures in Megaprostheses: Algorithmic Approach to Treatment.

With increases in both life expectancy and the number of patients with endoprosthetic replacements, more periprosthetic fractures are expected to occur. Periprosthetic fractures related to megaprostheses present a treatment challenge, with a high incidence (one-third of affected patients) of secondary revision as a result of prosthetic loosening, infection, nonunion, refracture, or even amputation. Efforts to improve endoprosthetic reconstruction should focus on preventing postoperative complications. Understanding the causes of complications and strategies to avoid them could lead to significant improvements in implant survival, limb function, and patient outcomes. This article presents a concise review of the current literature and an algorithmic approach to reconstruction of these complex injuries. [Orthopedics. 2017; 40(3):e387-e394.].
