Introduction

The shoulder joint provides a wide range of
motion but the price of mobility is reduced
stability.
Common injuries sites include rotator cuff,
capsule, ligaments, bursae, and the glenohumeral
joint.
 The shoulder joint cannot have full range of
motion without the cooperation of the shoulder
girdle muscles.

Bones
The scapula, clavicle, and humerus
serve as attachments for most of the
shoulder joint muscles.

The shoulder joint is known as the
glenohumeral joint and is classified as
enthrodial (ball-and-socket).
 The glenoid labrum – cartilaginous
ring that surrounds the glenoid fossa.
