Posterior Glenoid Bone Loss and Instability: An Evidence-based Approach to Diagnosis and Management

Posterior glenohumeral instability is an underappreciated cause of disability that may necessitate surgical intervention to allow functional glenoid restoration. However, posterior glenoid bone abnormalities, when sufficiently severe, may contribute to persistent instability despite a well-performed capsulolabral repair. Recognition and understanding of these lesions is critical to both surgical decision making and execution of the surgical plan. Numerous procedures have been described to address posterior instability including recent developments in arthroscopic grafting techniques. The purpose of this article was to provide an evidence-based strategy for diagnosis and management of posterior shoulder instability and glenoid bone loss.

Automated summary

Posterior glenohumeral instability is an often overlooked cause of disability requiring surgical intervention. Even with a well-performed capsulolabral repair, severe posterior glenoid bone abnormalities can still lead to persistent instability. Understanding and recognizing these lesions is crucial for effective surgical decision making and implementation. Various procedures, including recent advancements in arthroscopic grafting techniques, have been developed to address posterior instability. This article aims to provide an evidence-based strategy for diagnosing and managing posterior shoulder instability and glenoid bone loss.
