Specialized Toolkit Series: Shoulder Instability-Dynamic Anterior Shoulder Stabilization

Dynamic Anterior Shoulder Stabilization – You Need This In Your Bag of Tricks

Video Transcription

Video Summary

Tiago Martino discusses dynamic anterior shoulder stabilization (DAS) as a surgical option for anterior shoulder instability with subcritical bone loss (<20%). DAS transposes the long head of the biceps tendon to the anterior glenoid rim through the subscapularis split to replicate latarjet procedure effects but with fewer complications. The technique involves creating a subscapularis split and fixing the biceps tendon to the glenoid. Biomechanical studies show DAS reduces instability comparable to the latarjet for 10-20% bone loss, but it’s not recommended beyond 20%. Early clinical outcomes show low recurrence rates (4-6%). Martino prefers DAS over isolated Bankart repair except in contact athletes.
