Arthroscopic All-Intra-articular Revision Eden-Hybinette Procedure for Recurrent Instability After Coracoid Transfer.

Abstract

Failure, in the form of recurrent shoulder instability, following a coracoid transfer procedure presents a challenging problem. Successful treatment with a revision Eden-Hybinette procedure, by both an open and arthroscopic approach using screws to secure the bone graft, has previously been reported. However, both the open and arthroscopic approach have required careful dissection through the distorted soft-tissue anatomy in the anterior compartment in front of subscapularis to gain access to the front of the glenoid through a muscle split. In this article, we describe a modification of an arthroscopic Eden-Hybinette technique that is undertaken intra-articularly and only requires portals through the rotator interval. This technique avoids having to undertake any extra-articular dissection in the anterior compartment and can address potential problems with retained metalwork and pre-existing anchor voids within the glenoid. In this Technical Note, we describe and highlight the pearls and pitfalls of an all-intra-articular arthroscopic revision Eden-Hybinette procedure.
