Long-term outcomes with a partial neck-preserving cementless short stem in primary total hip arthroplasty for young patients: a single center first one hundred cases

Purpose This study aimed to assess the long-term results of THA patients who received a cementless short stem regarding clinical outcomes, bone changes, complications, and incidence of femoral revision. Methods A retrospective evaluation of the first 100 THA employing a type 2B cementless stem (Mini hip stem, Corin, Cirencester, United Kingdom) by the same surgeon at one institution. We only include patients with 18 years or more, and with a minimum follow up of 8 years. Patient’s Harris hip score (HHS), the University of California, Los Angeles activity score (UCLA), and radiographic outcomes were evaluated. Results A total of 100 primary hip arthroplasties with Mini Hip stems were performed on 84 patients, with an average age of 47 years old. The median follow-up was 120 months (IQR 57.5-136.5), with 47 patients having a minimum 10-year follow-up. The patient’s HHS improved significantly ( p
