The superolateral portal for arthroscopy of the shoulder.

With the advent of arthroscopic procedures for the treatment of a variety of clinical conditions affecting the shoulder has come the need for better techniques for visualization of structural pathology, and better techniques for visualization of intracapsular structures during operative procedures. We present a new portal for shoulder arthroscopy that is safe to insert, providing a panoramic view of the glenohumeral joint (especially anteriorly), and allowing unobstructed observation of large instruments passed through more traditional anterior portals nearby. The superolateral portal is particularly suited for use in anterior stabilization procedures of the shoulder, where it can be used for direct visualization of the anterior glenoid neck, thus permitting the surgeon to perform such tasks as debridement or mobilization of tissues, and placement of tacks or sutures.
