Summary

Total hip arthroplasty (THA) is a widely accepted procedure for the treatment of end-stage hip osteoarthritis. Neck preserving short stems have gained popularity in recent years, as they aim to preserve proximal femoral bone stock and enable a more physiological load transfer. However, the use of these stems in patients with specific femoral deformities, such as DORR Type C femurs, can present unique challenges. DORR Type C femurs are characterized by decreased cortical bone thickness and increased medullary canal width, which can impact the fit and stability of the femoral stem component. Short stem total hip arthroplasty has emerged as a potential solution for these patients, as it aims to preserve proximal femoral bone stock and improve load transfer to the surrounding bone. This study seeks to investigate the measured subsidence of short stem total hip arthroplasty in patients with DORR Type C femur configuration and the clinical outcomes associated with this approach.
