This panel of experts with extensive experience in treating professional athletes to weekend warriors will provide insights into the latest understanding of pathologies and treatments patients with posterior shoulder instability.

Learning Objectives:

• Identify important history and physical exam findings of those with posterior instability and how they differ from anterior instability patients.
