Editorial Commentary: Dynamic Anterior Stabilization via Biceps Tenodesis to the Glenoid Is an Option for Anterior Shoulder Instability With Subcritical Glenoid Bone Loss

Abstract

A nuanced approach to treatment of anterior shoulder instability is encouraged, particularly in patients with subcritical glenoid bone loss. In patients with bone loss, recurrent instability after isolated arthroscopic Bankart repair has dampened enthusiasm for this procedure. Adjunctive treatment with remplissage or dynamic anterior stabilization via biceps tenodesis to the glenoid is an alternative to bone transfer procedures, which are effective but have higher complication rates. Dynamic anterior stabilization or tenodesis of the long head of the biceps to the 3-o’clock position on the glenoid through a subscapularis split is biomechanically superior to isolated Bankart repair for reducing anterior translation, even in the setting of minor glenoid bone loss due to a sling effect similar to that produced by the Latarjet procedure. A disadvantage is placement of a large implant into the small space of the anterior glenoid and creation of a soft-tissue defect in the capsule.
