Modular Well-Fixed Hip Revision Stem Fracture: A Case Report and Literature Review

Fabio Pessina et al. Arch Bone Jt Surg. 2024.

Abstract

This study presents a case of repeated prosthetic fractures in a modular hip prosthesis in a 56-year-old male patient. After the initial implantation of a modular total hip prosthesis in 2006, the patient experienced two instances of prosthetic implant fractures over seventeen years. In this study, we analyze the clinical case, explore potential underlying causes of this complication, and delve into current indications and strategies for the revision of fractured prosthesis stems. The discussion is informed by a literature review and underscores the significance of selecting appropriate revision techniques to address this challenge.

Keywords: Fracture; Hip arthroplasty; Modular; Revision; Well-fixed stem.
