Abstract
Introduction
Optimal femoral stem fixation for hemiarthroplasty in older adults with displaced intracapsular fractures remains controversial. Cemented stems may reduce mechanical failure, but cementation carries risks. This study compared mortality and complications after cemented versus uncemented hemiarthroplasty in patients aged 75 years or older.
Methods
We performed a retrospective study of consecutive patients aged 75 years or older who underwent hemiarthroplasty for intracapsular fracture between January 2015 and April 2022. Patients were grouped by stem fixation and followed until death or censoring in December 2025, allowing at least three years of follow-up. Outcomes included periprosthetic femoral fracture, dislocation, periprosthetic joint infection, a composite of any complication, and all-cause mortality from the early postoperative period to 3 years. Multivariable Cox regression was used for 3-year mortality, and a Fine-Gray competing risk model, with death as the competing event, was used for 3-year complications.
