Massive irreparable rotator cuff tears (MIRCTs) represent a difficult situation especially in painful and pseudoparalytic patients. A new technique, consisting of an arthroscopic implantation of an inflatable biodegradable “balloon”, serving as a temporary subacromial spacer, has been introduced recently for MIRCTs. The purpose of this paper is: 1) to present the efficacy and safety results of patients treated with the balloon; 2) to show that these results are maintained over time, after balloon degradation; 3) to compare these results to published results of other procedures available for MIRCTs. This paper presents the first group of 22 patients (females/males 13/8, one bilateral), treated in a single-surgeon, prospective and on-going series of 97 shoulders operated with the balloon, since September 2010. The mean age is 69.3 (52–86) and the average follow-up 52.5 months. The balloon is inserted arthroscopically and inflated with saline. The procedure is simple with a short operative time (10–20 min). It can also supplement partial repairs, especially of the subscapularis, as well as repairable massive tears with bad tissue quality. The balloon is not used in severe cuff tear arthropathy or complete insufficiency of the external rotators. Final outcome scores, Constant (CS) and UCLA scores are obtained at least three years after complete balloon degradation (which occurs within 12 months), and are also compared to those of other treatments available for MIRCTs. No device related safety issues were observed in this group. Good results, including rapid pain relief and restoration of active motion, which maintained over time, are obtained in 85% of the patients. The CS has improved significantly (average preop/postop: pain 2.9/12.7; ADL 6.8/17.4; ROM 22.8/36.6; strength 3.1/5.6; TOTAL 35.8/72.3; NORMATIVE 42.7/86.4). The UCLA score has also improved significantly (preop/postop: pain 1.9/8.6; function 3.9/8.6; active flexion 3.5/4.5; strength in flexion 2.4/3.4; satisfaction 0/4.5; TOTAL 11.2/29.8). Pseudoparalysis is reversed (average preop/postop flexion 86°/156.8°). The CS and UCLA score for the balloon are superior compared to published results of debridement, biceps tenotomy/tenodesis, partial repair, tuberoplasty and latissimus dorsi transfer. CS (86.4/63.8), CS pain (12.7/11.9) and flexion (156.8/128.0) are also better for the balloon compared to the reverse prosthesis. The balloon is indicated for MIRCTs, as well as reparable massive tears with a high risk of retear. The implantation is a straightforward and short procedure, which has excellent safety profile and positive effect on painful MIRCTs including pseudoparalysis. The balloon provides significant improvement in the CS and UCLA score that persists way beyond its degradation. The balloon patients' shoulder function is superior to the other available treatment options. Additional studies are needed to further confirm the effectiveness of the balloon as a first line treatment for MIRCTs

Aims

The aim of the study was to develop a quantitative scoring system to predict whether a large-to-massive rotator cuff tear was arthroscopically reparable prior to surgery.

The outcome of an anatomical shoulder replacement depends on an intact rotator cuff. In 1981 Grammont designed a novel large-head reverse shoulder replacement for patients with cuff deficiency. Such has been the success of this replacement that it has led to a rapid expansion of the indications. We performed a systematic review of the literature to evaluate the functional outcome of each indication for the reverse shoulder replacement. Secondary outcome measures of range of movement, pain scores and complication rates are also presented.

Study design: Retrospective study of 34 patients with a massive rotator cuff tear, who were treated with an arthroscopic tuberoplasty, debridement of the degenerate cuff and biceps tenotomy. Objectives: To evaluate the clinical outcome of a reversed decompression at the medium term follow up. Summary of background data: Rotator cuff repair can become impossible for massive tears in the elderly. If conservative management fails, a reverse total shoulder arthroplasty (RSA) is commonly used. However, Fenlin described in 2002 a tuberoplasty for this pathology and reported good to excellent results. This procedure appears to be well tolerated as it is arthroscopic, not time consuming and not depending on intensive physiotherapy. In case of failure, a primary RSA is still possible. Methods: 36 patients treated with a tuberoplasty between February 2002 and September 2006 were identified. One patient deceased, one patient developed Alzheimer dementia, leaving 34 patients available for follow-up. They completed the SF-36 questionnaire and the Simple shoulder test. They were clinically reviewed and scored with the Constant-Murley score. All 34 had complete radiographic work-up (x-ray; ultrasound) preoperatively and at final follow up. Results: Median age at operation was 71 years (range: 52,5 – 82,16). Mean follow-up was 3,1 years (SD: +/− 0,75). Mean operating time was 35 minutes (SD: +/− 12.33). There were no surgical complications. Postoperatively, there was an uneventful recovery in all patients. At final follow-up, two patients were revised to a RSA. One patient was revised after 9 months because of continuous pain and loss of function. The second patient developed a complete osteonecrosis and was revised after one year. The 32 remaining patients had a preoperative Constant-Murley score adjusted for age and gender of 34,8. This improved to an average of 84 at final follow up. The simple shoulder test improved from an average of 1,8 to 8,4. The average decrease of subacromial space was 2,34 mm and the loss of glenohumeral joint space was 0,57. Finally, the preoperative grade of arthrosis was 0,46 compared to a postoperative average of 1,1. At final follow-up, 85% (27/32) were either satisfied or very satisfied with the result. 12,5% (4/32) appreciated the result as only fair. 2,5% (1/32) was dissatisfied, but didn’t consider revision surgery. Conclusion: We conclude that a tuberoplasty with rotator cuff debridement and biceps tenotomy is a reliable treatment for massive rotator cuff tears in the elderly at medium follow up. In case of failure, revision to RSA is still a valuable option
