EP8.33 Evaluating Calcar Engagement and Post-Implantation Remodeling in Two Collared, Triple Taper Stems
Abstract Background Femoral stem collars are intended to improve axial stability and load transfer following total hip arthroplasty (THA). However, substantial variability exists in collar geometry across implant systems, and how collar size and collar–calcar interaction influences femoral remodeling and the risk of me...
