Dynamic Anterior Stabilization Using the Long Head of the Biceps for Anteroinferior Glenohumeral Instability

Anteroinferior glenohumeral instability can be treated by variants of the Bankart repair, remplissage, and the Latarjet procedure, although all options remain associated with complications, including recurrence, stiffness, persistent pain, apprehension, and dislocation arthropathy. The authors therefore thought of a concept of dynamic anterior stabilization to treat anteroinferior glenohumeral instability by transferring the long head of the biceps within a subscapularis split to the anterior glenoid margin, thereby creating a "sling effect" by using a conservative technique. A standard Bankart repair is then to re-establish the labral damper effect. The main benefit of the dynamic anterior stabilization procedure is that it grants the "sling effect," but is easier and safer than arthroscopic Latarjet. It does not require screws nor traction of the coracoid process, and should therefore reduce the risks of neurologic damage. Furthermore, the procedure can be performed with only 3 small incisions, because it does not require coracoid transfer, which eliminates risks of nerve dissection, graft overhang, and cortical resorption, hence reducing the probability for dislocation arthroplasty. Lastly, the pectoralis minor remains intact, which would avoid scapular dyskinesis.
