Evaluation and Management of Failed Shoulder Instability Surgery

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Surgical Outcomes

Background:

• Failed shoulder instability surgery encompasses more than recurrent dislocations, including subluxation and patient dissatisfaction.
• Understanding the multifactorial reasons for surgical failure is essential for effective management.

Purpose of the Study:

• To review the evaluation and management strategies for failed shoulder instability surgery.
• To identify key factors contributing to surgical failure and guide treatment decisions.

Main Methods:

• A comprehensive literature and online content review was conducted.
• Focus on identifying causes of failure and recommended surgical interventions.

Main Results:

• Key failure factors include poor patient selection, technical errors, and bone loss (over 80% of failures).
• Glenoid bone loss and engaging Hill-Sachs lesions are critical determinants.
• CT scans are vital for quantifying bone loss; treatment varies based on bone loss severity and patient activity.

Conclusions:

• Shoulder instability surgery failures stem from multiple causes.
• Accurate diagnosis of failure etiology is paramount for selecting the appropriate revision strategy.
