Document Summary

Anterior dislocation: common mechanism: abduction (close to 90 deg. ), lateral rotation, axial (traumatic) load to the shoulder from behind pushing it forward. Recognition: appearance: prominence of humeral head (with someone with less muscle), deltoid contour - you will see: bulge in armpit, fossa, acromion, but not deltoid. Armpit nerve, sensory and motor disruption with anterior dislocation. Where will they have sensory disruption and what muscles will be affected? (independent study: deltoid will be affected and sensory loss will occur below the shoulder around deltoid. Bankart lesion: detachment of glenoid labrum from glenoid (80% of people who have their first dislocations will have this). When a labrum/lip is damaged, you will have dislocations frequently. Slap lesion: superior labrum from anterior to posterior. The tendon of the long head of biceps can tear the labrum (like a pop can) when traction is present. Shoulder ripped out of socket, tear through labrum most of the time.
