Abstract

A massive rotator cuff tear is not necessarily irreparable. Number of tendons involved, muscle-tendon unit quality, and decreased acromionhumeral distance (AHD) are as important as tear size in determining reparability of lesion. Massive and irreparable rotator cuff tears cannot be anatomically repaired to the bone and are a common source of pain and disability even in middle-aged patients. In these patients when conservative management has failed, it is possible to perform different surgical techniques. A functional repair can help to restore the horizontal force couple of the cuff on the humeral head and to increase the AHD. Debridement of irreparable tears and biceps tenotomy or tenodesis can have a role in low functional demand patients but results deteriorate over time. Recently, several commercially available tissue-engineered biological and synthetic scaffolds have been developed to augment rotator cuff repairs. The aim is to provide a mechanical improvement in case of poor quality tissue at time zero and give a support to have a better cuff healing. In selected cases, the scaffold can be used also to bridge tendon defect. Patients who not have pseudoparalysis, cuff tear arthropathy and with intact deltoid function can benefit from tendon transfers with satisfactory outcomes. These different procedures should be chosen for each patient with selected criteria and after a satisfactory explanation about the really possible expectation after surgery.
