Anatomy
The capsular ligament of the shoulder surrounds the glenohumeral joint.
It attaches from the scapula, just outside the glenoid labrum, and medial to the supraglenoid tubercle to allow for the attachment of the biceps brachii. It attaches onto the anatomical neck of the humerus, except medial where it extends down to the surgical neck to allow some slack for abduction.
Functions
Support and stability for the glenohumeral joint.
Clinical
Frozen shoulder or adhesive capsulitis is the inflammation and stiffness of the capsular ligament. It greatly reduces movement and can lead to chronic pain.
