AI Technical Summary

Problems solved by technology

This can lead to loosening of the modular joints and the formation of undesirable metal debris
Hip implants with large-diameter femoral heads and mobile inserts are particularly prone to this situation due to the increased lever arm and implant diameter, which lead to greater frictional torque and moment loads at the joint

Abstract

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.
