How To Reduce Anterior Shoulder Dislocations Using Scapular Manipulation
Relevant Anatomy for Scapular Manipulation
In most anterior dislocations, the humeral head is trapped outside and against the anterior lip of the glenoid fossa. Reduction techniques must distract the humeral head away from the lip and then return the humeral head into the fossa. Deficits of the axillary nerve are the most frequent nerve deficits with anterior shoulder dislocations. They often resolve within several months, sometimes soon after the shoulder reduction. Axillary artery injury is rare with anterior shoulder dislocations and suggests possible concurrent brachial plexus injury (because the brachial plexus surrounds the artery).
