Ultrasound-Guided Deflation and Arthroscopic Removal of a Migrated Subacromial Balloon Spacer

Full-thickness massive irreparable rotator cuff tears present a demanding challenge for the surgeon. The subacromial balloon spacer is a novel biodegradable implant used to treat massive, irreparable rotator cuff tears. There have, however, been several isolated reports of balloon migration. This Technical Note describes ultrasound-assisted balloon deflation followed by arthroscopic removal of a symptomatic dislodged balloon.
