FEMORAL HEADS, MOBILE INSERTS, ACETABULAR COMPONENTS, AND MODULAR JUNCTIONS FOR ORTHOPEDIC IMPLANTS AND METHODS OF USING FEMORAL HEADS, MOBILE INSERTS, ACETABULAR COMPONENTS, AND MODULAR JUNCTIONS FOR ORTHOPEDIC IMPLANTS

摘要

Femoral heads, mobile inserts, acetabular components, and modular junctions for orthopedic implants, e.g., hip replacement implants, and methods of using femoral heads, mobile inserts, acetabular components, and modular junctions for orthopedic implants are provided. Prosthetic femoral heads, mobile inserts, and acetabular components are provided that can alleviate soft tissue impingement, reduce implant wear, and/or reduce frictional torque. Modular junctions are provided that can minimize the incidence of loosening and micromotion that can occur at modular junctions of orthopedic implants.
