摘要

patent summary: "Femoral heads, movable inserts, acetabular components and modular joints for orthopedic implants and methods for using femoral heads, movable inserts, acetabular components and modular joints for orthopedic implants". The present invention relates to femoral heads, movable inserts, acetabular components and modular joints for orthopedic implants, for example hip replacement implants and methods for using femoral heads, movable inserts, acetabular components and modular joints for orthopedic implants. Prosthetic femoral heads, movable inserts and acetabular components are provided which can alleviate soft tissue collision, reduce implant wear and / or reduce frictional torque. Modular joints are provided which may minimize the incidence of loosening and micromotion that may occur in modular joints of orthopedic implants.
