Familiari F, Nayar SK, Russo R, et al. - This study was undertaken to explore the correlations between clinical/demographic parameters and Constant-Murley (CM) scores after subacromial balloon placement for massive, irreparable rotator cuff tears (MIRCTs) and to assess implant survival, shoulder function, and patient satisfaction. Researchers prospectively examined individuals with rotator cuff tears deemed irreparable on preoperative MRI for whom nonoperative therapy was unsuccessful and who had undergone balloon placement from 2014–2017 with a minimum 1-year follow-up. They evaluated shoulder function applying CM scores and the 12-Item Short-Form Health Survey (SF-12). The analysis enrolled a total of 51 patients (22 women) with a mean age at surgery of 63 years (range, 50–78). It was shown that subacromial balloon spacer placement for MIRCTs was correlated with significant improvement in shoulder function at mean 3-year follow-up, limited need for revision surgery, and high patient satisfaction. At the final follow-up, greater postoperative acromiohumeral interval and lower preoperative CM scores prognosticated lower postoperative CM scores.
