Shoulder instability can occur in any direction and presents across a broad spectrum including traumatic dislocations, repetitive microinstability events or subluxations, and global joint laxity. The development of pain, functional decline, and articular pathologic condition is a multifaceted process that is influenced by the underlying bony morphology, biology of the surrounding soft tissue structures, dynamic coordination of the periscapular musculature, and patient factors such as age, activity level, and associated injuries. This article will focus on the younger, active patient with instability due to deficiencies in the capsulolabral complex and dynamic stabilizers.
