What type of GH instability is most common?

Anterior instability is the most common form of glenohumeral instability and may be associated with nerve injury. The diagnosis of anterior, posterior or multidirectional instability is based on a thorough history and physical examination that includes specific provocative maneuvers.

What causes deep sulcus sign?

A sulcus is defined as a depression greater than a finger breadth between the lateral acromion and the head of the humerus 2).

What is the purpose of the sulcus test?
