Subacromial Access in Shoulder Arthroscopy Using a Posterior-to-Anterior Cannula-Guided Technique.

ABSTRACT: Accessing the subacromial space remains a fundamental yet challenging step in shoulder arthroscopy, particularly during rotator cuff repair. Limited space, bursitis, and adjacent tissue inflammation often complicate visualization and scope advancement. This technical note presents a reproducible and efficient 2-portal technique for subacromial access using a metal arthroscopic sheath, trocar, and rigid cannula. The procedure begins with creation of a standard posterior portal through which the sheath is advanced beneath the acromion using wrist-guided flexion-extension to identify anatomic landmarks. The sheath is then passed lateral to the coracoacromial ligament and retrieved from the anterior portal under direct visualization. A 6.0-mm cannula is introduced into the rotator interval and
