Position: abduction and external rotation
Displaces: antero-medially
What three structures are at risk of damage?

What are the five lesions that can occur due to dislocation
Hills-Sachs Bankart SLAP HAGL ALPSA
Describe a Hills Sachs lesion
Fracture on postero-lateral head of humerus due to impact of rim of glenoid
Describe the Bankart lesion

What does SLAP stand for?
Superior labrum anterior and posterior
What does HAGL stand for?
