Context: Posterior shoulder instability is a commonly misdiagnosed disorder in many competitive athletes.
Type of Study: Clinical review.
Evidence Acquisition: Relevant studies on posterior shoulder instability from 1950 to 2010 in PubMed and Cochrane databases were reviewed.
Results: A total of 107 studies were reviewed.
Conclusion: Patients who have undergone at least 6 months of physical therapy and still experience instability symptoms should be considered for surgical stabilization directed at their underlying pathology.
