Acromioplasty/acromionectomy is another term for shoulder arthroscopy. A shoulder arthroscopy uses a small camera called an arthoscope to look at or repair tissues near the shoulder joint. The arthroscope is inserted through a small skin incision. It is done for shoulder problems that include: torn rotator cuffs, bone spurs, inflammation, arthritis, loose tissue removal, damaged biceps tendons or shoulder instability.
