Total hip arthroplasty utilizing an uncemented, flat, tapered stem with a reduced distal profile.

ABSTRACT:

Background

The aim of this study was to report the midterm results of an uncemented, flat, and tapered femoral stem with a reduced distal profile.

Methods

219 total hip arthroplasties were performed using this stem between March 2007 and October 2012. Survival, radiographs, and modified Harris Hip Scores were analyzed.

Results

Twenty-two (11.1%) patients died from comorbidities but retained their hips; 18 (9.1%) patients were lost to follow-up. Of the remaining 179 hips, all stems remained in situ at a median follow-up of 8.4 (7.0-9.3) years. There was 97.5% (95% CI: 95.1-99.9) survival for all-cause revision with 4 hips revised for instability. Early stem subsidence was identified in 2 patients within 3 months postoperative measured at 4 mm in patient 1 and 3 mm in p
