Arthroscopic Anterior and Posterior Glenoid Bone Augmentation With Capsular Plication for Ehlers-Danlos Syndrome With Multidirectional Instability

Recurrent multidirectional shoulder instability is a difficult clinical problem. This can be compounded in patients with connective tissue diseases such as Ehlers-Danlos syndrome. We present an all-arthroscopic technique involving extra-articular anterior and posterior glenoid bone grafting to augment a capsular repair in a patient with Ehlers-Danlos syndrome and recurrent multidirectional shoulder instability. Graft options include either distal tibial allograft or iliac crest autograft. Anterior graft placement uses a dilated far medial portal using an inside-out technique. The posterior graft is placed through a dilated posterior portal. A 1-mm edge of anterior and posterior glenoid rim is denuded of cartilage for later capsular repair, and grafts are secured flush to the osseous surface. A capsular plication is then completed and repaired to the prepared native glenoid surface, using the grafts as extra-articular osseous bumpers.
