Total Hip Arthroplasty Stems and Femur Strain During Implant Insertion: A Biomechanical Study of Single Taper, Double Taper, and Collared Monolithic Stems.

ABSTRACT:

Objective

In total hip arthroplasty (THA), intraoperative periprosthetic femoral fracture (IOPFF) is a significant concern, often occurring during femoral canal instrumentation and stem implantation due to proximal femur strain. However, the impact of different stem designs on this strain remains unclear. This study conducted a biomechanical analysis comparing strain patterns on the proximal femur during the implantation of three stem types: single taper, double taper, and collared stems. This study aims to explore if there is a difference in strain patterns placed on the proximal femur during the implantation of three different stem types: single taper, double taper, and collared stems?

Methods

There were 24 cadaveric femurs randomly assigned to three groups based on implan
