The treatment of irreparable massive rotator cuff tears with inspace balloon: rational and medium-term results

BACKGROUND AND AIM OF THE WORK: The treatment of irreparable massive rotator cuff tears (MIRCTs) represents a challenge for the orthopedic surgeon both for the affected population and for the intrinsic characteristics of the injury. There are different types of treatment ranging from bursectomy to reverse shoulder prosthesis and subacromial spacers. The aim of the work is to establish the clinical and functional improvement of patients treated with subacromial spacer. METHODS: we conducted 2 studies: the first analyzing a sample of 24 patients (14 females and 10 male, mean age 65.7 years) operated between 2015 and 2017 whose last follow up dates back to October 2021 and a second one analyzing 55 patients (including patients of the first sample) (30 females and 25 males, mean age 64 years) over a period of time from 2015 to 2021. The mean follow up was 56 months. All patients were diagnosed with irreparable massive rotator cuff tears and treated with subacromial spacer. RESULTS: the result in both studies was an increase of Constant score, tripled from the pre-operative values, in ROM, doubled, and a reduction of VAS. CONCLUSIONS: the clinical results are encouraging and the use of the subacromial spacer could be a valid surgical alternative for patients with MIRCTs. However, we needed randomized trials with long-term follow-up.(www.actabiomedica.it)
