Bursoscopic evaluation for degree of rotator cuff tear using an air-infusion method.

This article presents a method of bursoscopic examination with use of a glenohumeral air-infusion technique for the detection of full-thickness tears hidden by bursal tissue. We inflated the glenohumeral joint with 50 to 60 mL of air while simultaneously observing the joint with bursoscopy for the detection of air bubble leakage. The air-infusion technique is valuable in detecting full-thickness tears and useful for evaluating the patency of repair.
