Summary

This presentation offers a detailed analysis of shoulder instabilities, covering their historical context, unique biomechanics, common pathologies, and a spectrum of individualized surgical treatment options for athletes, emphasizing the critical need to address both glenoid and humeral defects to prevent recurrence.

Key Points

  • Shoulder instability is a prevalent condition, particularly among athletes, characterized by the shoulder's unique anatomy allowing maximum range of motion with limited bone support. 
  • The shoulder's stability relies on a complex interplay of static stabilizers like the labrum and glenohumeral ligaments, and dynamic stabilizers such as the rotator cuff and biceps tendon. 
  • A high recurrence rate of 35-40% after a primary shoulder dislocation is attributed to irreversible injuries, including complete inferior glenohumeral ligament rupture, capsular rupture, and Hill-Sachs lesions. 
  • Shoulder instability is understood as a bipolar lesion, with Bankart lesions affecting the glenoid during the initial dislocation phase and Hill-Sachs lesions occurring on the humeral head during the reduction phase. 
  • Treatment decisions are highly individualized, taking into account patient age, sex, sport type, joint laxity, dominant side, and the presence of concomitant injuries like HAGL, ALPSA, rotator cuff tears, and the “on-track” or “off-track” status of Hill-Sachs lesions. 
  • Effective management of shoulder instability requires a thorough assessment of both glenoid and humeral defects, along with dynamic intraoperative examination, to achieve optimal outcomes and prevent recurrence. 
  • Isolated Bankart repair often has an unacceptably high failure rate, especially in professional athletes, highlighting the need for more comprehensive surgical approaches. 
  • Surgical strategies are tailored to the extent of bone loss and lesion types, ranging from soft tissue repairs (Bankart, Remplissage for Hill-Sachs) to bone augmentation procedures like Latarjet or bone blocks for critical glenoid bone loss (over 15%). 
  • For subcritical glenoid bone loss (10-15%), Dynamic Anterior Stabilization (DAS) involving biceps transfer, often combined with Remplissage and Bankart repair, offers a robust solution.
