Short femoral stem in total hip arthroplasty: stable fixation and low complication rates in elderly patients.

Background: We present the result of our experience in using a short femoral stem in elderly patients (>70 years of age) compared to patients younger than 70 years.

Methods: Data were prospectively collected on 138 patients who underwent 148 primary total hip arthroplasty (THA), with a conservative short stem between November 2010 and June 2014. The cohort was divided into 2 groups: the study group (group 1) comprised 57 patients (60 THA) over 70 years of age at the time of surgery, with a mean age of 75.
