The Socket and Ball Joint: A Comprehensive Guide

The socket and ball joint, also known as the spherical joint, is a type of synovial joint that allows for a wide range of motion, including flexion, extension, abduction, adduction, and rotation. It is found in many parts of the body, including the shoulder, hip, and thumb.

Anatomy of the Socket and Ball Joint

The socket and ball joint consists of two bones: a cup-shaped socket and a ball-shaped head. The head of the bone fits into the socket, and the two bones are held together by a capsule of ligaments. The capsule is lined with a synovial membrane, which produces a lubricating fluid that reduces friction between the bones.
