Postoperative Periprosthetic Fractures in Hip Fracture Patients: Exeter vs Anatomic SP2 Lubinus Stem

Femoral Neck Fractures, Periprosthetic Fractures

Recent studies have indicated a high incidence of postoperative periprosthetic femoral fracture in elderly patients treated with two commonly used cemented polished, tapered femoral stems. The aim of this study was to compare the prevalence and incidence rate of PPF in a cohort of elderly with femoral neck fractures (FNF) treated with either a collarless, polished, tapered stem (Exeter) or an anatomic matte stem (Lubinus SP 2). Patients and Methods In a multicentre retrospective cohort study 2529 patients 60 years and above, with a FNF as indication for primary surgery with a cemented hip arthroplasty were included. Patients were treated either with a polished tapered Exeter stem or a matte anatomic Lubinus SP12 stem according to the surgeons preference or to the praxis of the present department. The incidence of perprosthetic femoral fractures Hip-related complications and repeat surgery were assessed at a minimum follow-up of 2 years postoperatively.
