Background: Most cases of impossibility of elevation in rotator cuff tears recover gradually with reduction of pain. We studied recovery cases of impossibility of elevation in massive and large rotator cuff tears. Methods: 12 patients with 9 massive rotator cuff tears and 3 large ones had complained of impossibility of elevation, they became able to elevate later with conservative treatment. We determined impossibility of elevation to be below 90 degrees, and recovery to be 150 degrees and over. 5 males and 7 females with an average age of 74 years old took part in the study. 9 cases were right side and 3 were left, and 10 were dominant side and 2 were non-dominant side. 11 cases in 12 had trauma or heavy lifting as the cause of a turn for the worse. Results:The average term from getting worse to recovery was 86.1 days (11-175 days). Average elevation angle was 41.7 degrees at the first examination and 172.5 degrees at the last evaluation. Discussion: We show the average recovery term is 3 months and in the longest case 6 months. These terms may be the indicator that suggest to us the choice between operative treatment and conservative treatment.
