Periprosthetic Femur Fractures Around a Loose Femoral Stem.

Abstract

A critical component in the evaluation of a patient with a periprosthetic hip fracture is determination of stem stability. Failure to critically evaluate preoperative radiographs and subsequently intraoperative stem position may result in an incorrect treatment algorithm and early catastrophic failure of the implant construct. In 2018, this is becoming a larger issue as demand for revision total hip arthroplasty increases. Several factors contribute to the type of implant used in these fractures and depend on age, activity level, comorbidities, and available bone stock. The purpose of this article is to review the evaluation of periprosthetic hip fractures around a loose stem and provide tips and tricks for their management to allow for a successful, long-lasting outcome.
