What are the three joints of the shoulder?

Sternoclavicular, acromioclavicular and glenohumeral joints


What is a banker lesion?

an injury of the anterior (inferior) glenoid labrum of the shoulder due to anterior shoulder dislocation
A bony bankart is a Bankart lesion that includes a fracture in of the anterior-inferior glenoid cavity of the scapula bone


What is humeral avulsion?

Humeral avulsion of the glenohumeral ligament (HAGL) is defined as an avulsion (tearing away) of the inferior glenohumeral ligament from the anatomic neck of the humerus


What is Hill-sachs lesion?

is a cortical depression in the posterolateral head of the humerus. It results from forceful impaction of the humeral head against the anteroinferior glenoid rim when the shoulder is dislocated anteriorly.


What is an ACJ injury?

Acromioclavicular separation occurs as a result of a downward force being applied to the superior part of the acromion, either by something striking the top of the acromion or by falling directly on it. The injury is more likely to occur if the shoulder is struck with the hand outstretched.


What are the rotator cuff disorders?

Supraspinatous is most commonly involved as is passes beneath the acromion and the acromioclavicular ligaemnt - this is a fixed space - so swelling of the suprspinatous muscle, excessive fluid within the subacromial bursa or subacromial bony spurs may produce a significant impingement when the arm is abducted.
Blodd supply to there is poor - repetetitive trauma can nake tendon susceptible to degenerative change - calcium deposition - extreme pain - partial or full thickness tears may occur - can be unsymptomat
