Anterior shoulder dislocation while carrying a frail elder. A dislocated shoulder is a condition in which the head of the humerus is detached from the glenoid fossa. [2] Symptoms include shoulder pain and instability. [2] Complications may include a Bankart lesion, Hill-Sachs lesion, rotator cuff tear, or injury to the axillary nerve. [1]
Axillary nerve palsy is a neurological condition in which the axillary (also called circumflex) nerve has been damaged by shoulder dislocation. It can cause weak deltoid and sensory loss below the shoulder. [1] Since this is a problem with just one nerve, it is a type of Peripheral neuropathy called mononeuropathy. [2]
The mechanism is thought to be severe hyperabduction and external rotation of the arm, combined with retraction of the scapula. The distal clavicle is found in 2 orientations, either subacromial or subcoracoid. With the subcoracoid dislocation, the clavicle becomes lodged behind the intact conjoined tendon.
The two mechanisms that can occur are traction and heavy impact. [22] [23] Traction, also known as stretch injury, is one of the mechanisms that cause brachial plexus injury. The nerves of the brachial plexus are damaged due to the forced pull by the widening of the shoulder and neck. This is a closer look at the traction mechanism at the ...
X-ray at right shows same shoulder after reduction and internal rotation, revealing both a Bankart lesion and a Hill-Sachs lesion. Diagnosis can be suspected by history and physical examination which is usually followed by imaging. Because of the mechanism of injury, apprehension of anterior dislocation is common with provocative maneuvers.
Cunningham shoulder reduction was originally published in 2003 [1] and is an anatomically based method of shoulder reduction that utilizes positioning (analgesic position), voluntary scapular retraction, and bicipital massage. It is designed for true anterior/subcoracoid glenohumeral dislocations in patients who can fully adduct their humerus. [2]

The mechanism of action has been described as a triple blocking effect: conjoint tendon of shoulder i.e short head of the biceps and coracobrachialis, acting as a sling on the subscapularis and capsule with the arm abducted and externally rotated; increasing or restoring the glenoid bone; and
