Artificial Hip Joint Parts: A Comprehensive Guide

The parts of an artificial hip joint include:

Femoral component or stem: This is a metal component that is inserted into the hollow part of the femur (thigh bone). It typically consists of a long stem that anchors into the femur.
Femoral head: This component is a metal ball that replaces the head of the femur. It is attached to the femoral stem and acts as the new 'ball' in the joint.
Acetabular component or socket: This is a cup-shaped component made of metal or ceramic that replaces the damaged hip socket (acetabulum) in the pelvic bone.
Liner: The liner is a plastic, ceramic, or metal insert that fits inside the acetabular component. It provides a smooth surface for the femoral head to move against.
Acetabular screws: These are used to secure the acetabular component to the pelvic bone for stability.
Acetabular shell: This is a metal cup that holds the liner in place and is fixed to the acetabular screws.

These components work together to replace the damaged or diseased hip joint, allowing for improved mobility and pain relief.
