Superomedial Portal (Ejnisman's Portal) and Modified "Chicken-Wing" Patient Position for Scapulothoracic Arthroscopy.

Scapulothoracic arthroscopy is performed to treat scapulothoracic joint disorders, such as scapulothoracic bursitis, snapping scapula, and osteochondroma of the anterior scapula surface, and in the extraction of firearm projectiles. This article describes this treatment using an alternative superomedial portal and modified chicken-wing position to improve access to the scapulothoracic space and thus perform the procedure as safely as possible, with less morbidity and excellent results for the patients.
