Figure 16-7 || Coracoplasty technique (right shoulder, 30 degree (A) and 70 degree (B-F) views). A. The rotator interval has been opened while preserving the comma tissue ( black comma symbol ) to show a coracoid (C) tip osteophyte. B. Before coracoplasty, less than a 3-mm coracohumeral interval is present with upper subscapularis (SSc) fraying (E) from impingement on the osteophyte. C. A high-speed burr is used to perform the coracoplasty from an ASL working portal with the instrument anterior to the comma. D. The end point of coracoplasty is a 7- to 10-mm coracohumeral interval and the conjoint tendon (CT) coplanar with the coracoid. F. Internal rotation and the posterior lever push bring the lesser tuberosity (LT) bone into the working space. H, humeral head.
