"It is often the result of chronic injury rather than acute dislocation; the incidence of ALPSA lesions increases in patients with multiple dislocations."
"Unlike the Bankart lesion in which the labrum and glenoid periosteum are avulsed from the underlying glenoid, an ALPSA lesion involves mobilisation of the labrum, which remains attached to the periosteum overlying the glenoid (thus sleeve). As a result, an ALPSA lesion may heal (as opposed to a Bankart lesion, which does not); however, it can do so in an abnormal position requiring identification and early surgical repair."
