Subacromial Balloon Spacer for Massive Irreparable Rotator Cuff Tears

Summary: This study compared the efficacy and safety of a subacromial balloon spacer and arthroscopic partial repair in the treatment of irreparable, posterosuperior massive rotator cuff tears. The results showed that both methods significantly improved symptoms in patients, and the subacromial balloon spacer group had advantages in terms of functional recovery and operative time.

Summary: This study investigated the associations between clinical and demographic parameters and Constant-Murley (CM) scores after subacromial balloon placement for massive, irreparable rotator cuff tears. Results showed a significant improvement in shoulder function postoperatively, limited need for revision surgery, and high patient satisfaction. A greater postoperative acromiohumeral interval and lower preoperative CM score predicted a lower postoperative CM score at final follow-up.
