Arthroscopic Metal-Free Bone Grafting

Bony glenoid defects frequently occur in patients with recurrent anterior shoulder instability. Free bone block procedures aim to restore the glenoid concavity and anatomy of the glenohumeral joint to reestablish stability. Various bone-grafting techniques have been published that have yielded satisfactory clinical and radiological outcomes in the long term. However, the structural integrity and clinical function of the subscapularis tendon may be compromised after open shoulder stabilization procedures.¹ The bone block cerclage is an innovative arthroscopic surgical technique that preserves the integrity of the subscapularis and provides a metal-free fixation of the bone graft.² Two interconnected FiberTape and TigerTape cerclage sutures provide a firm compression of the graft and a strong fixation that minimizes construct displacement at high loads.³
