Lesions Of The Shoulder ALPSA lesion - Everything You Need To Know - Dr. Nabil Ebraheim

Dr. Ebraheim’s educational animated video describes lesions of the shoulder - ALPSA Lesion.

ALPSA is a torn anterior inferior glenoid labrum. The labral ligament complex is displaced medially and shifted inferiorly. The labrum is displaced by the inferior glenohumeral (IGHL) ligament and the labrum is rolled up like a sleeve with an intact anterior scapular periosteum.
ALPSA is associated with a more severe injury and the labral part remains attached to the periosteum of the scapular margin and can be tethered in this abnormal location increasing the chances of further displacement and radiolocation.
ALPSA may need to be repaired early before it heals in an abnormal position, which will make the surgery difficult later on.
Perthes lesion is different! Nondisplaced avulsed anterior inferior labrum with medial stripping and an intact scapular periosteum.
