AANA/ISAKOS Knee and Shoulder Arthroscopy Course-Online Didactics (April 2024)-Posterior Instability

Posterior Instability_ Getting to the Back

Video Transcription

Video Summary

The talk addresses posterior shoulder instability, common in military and athletic populations, and surgical repair techniques. Using a lateral decubitus position, the speaker prefers an anterior superior lateral portal for optimal viewing and a posterior inferior/lateral portal for anchor placement at a 45-degree angle to the glenoid. Techniques include labrum repair, pinch-tuck capsular tightening for laxity, and managing associated lesions like reverse Hill-Sachs and capsular tears. Knotless and suture anchors are options, with careful balancing of repairs crucial for capsule and labrum injuries. Increasing recognition of posterior instability will lead to more surgeries requiring these precise approaches.
