Bankart Spectrum (4 stages)

GLAD: Superficial partial labral injury with cartilage tear. Stable
Perthes: Avulsed anterior labrum (only minimal displacement). Inferior GH complex still attached to periosteum. Intact periostium
ALPSA: Similar to Perthes, but medially displaced, “bunched up” inferior GH complex. Intact periostium.
True Bankart: Torn labrum, periostium distupted.
Bony Bankart: Anterior, inferior glenoid fracture.
