Recurrent anterior shoulder instability associated with bony defects.

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Anatomy

Background:

• Shoulder instability is often managed with arthroscopic stabilization.
• Bony defects of the glenoid or humerus present unique challenges in shoulder instability.
• Current management paradigms are shifting from open vs. arthroscopic to addressing bony defects.

Purpose of the Study:

• To highlight the challenges in managing shoulder instability with bony defects.
• To emphasize the importance of recognizing and quantifying bone loss.
• To discuss the shift towards bony procedures for specific instability cases.

Main Methods:

• Review of clinical history and physical examination findings.
• Utilization of advanced radiographic imaging for defect assessment.
• Comparison of nonoperative, soft tissue, and bony surgical interventions.

Main Results:

• Nonoperative treatments are often inadequate for large bony defects.
• Bony procedures may provide superior outcomes compared to soft tissue procedures in cases with significant bone loss.
• Surgical techniques for bony defects are complex and have a steep learning curve.

Conclusions:

• Accurate diagnosis of bony defects is crucial for successful shoulder instability treatment.
• A paradigm shift towards bony reconstruction is occurring for specific instability patterns.
• Addressing bone loss is paramount for achieving stable and functional shoulder outcomes.
