What are the four immediate complications to look for and the associated signs in the case of an antero-internal glenohumeral dislocation?

So I will just explain it

Explanation:

°°Mechanism of injury is usually a blow to an abducted, externally rotated and extended extremity.

°°It may also occur with posterior humerus force or fall on an outstretched arm.

°°On exam, the arm is usually abducted and externally rotated, and the acromion appears prominent

°°There are associated injuries in up 40% of anterior dislocations including nerve damage, or tears and fractures associated with the labrum, glenoid fossa, and/or humeral head.
