Extra-Articular Endoscopic BP Decompression—Surgical Technique

We describe all-endoscopic brachial plexus (BP) decompression. Surgery is performed with the patient in the beach-chair position with the usual arthroscopic instruments and pump. The first step is to create 2 portals at the area of the coracoid process and decompress the infraclavicular part of the BP at area of thoracic aperture and coracoid. The second step includes performing 2 portals at supraclavicular fossa and performing decompression of BP at interscalene space. The postoperative period includes a short period of sling immobilization (3-5 days), immediate passive motion after surgery, and active motion after removal of the sling.
