Anteroposterior radiographic and MRI studies were reviewed by a musculoskeletal radiologist to assess calcific tendonitis morphology, size, distance from cuff insertion, and any rotator cuff tear. An additional radiologist evaluated calcific tendonitis size, morphology, and location to evaluate the reliability of these variables.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      In the final cohort of 318 shoulders with calcific tendonitis, the incidence of concomitant rotator cuff tears was 56%. Of all 177 tears, 164 (93%) were partial\u2010thickness and 13 (7%) were complete. Type III calcification morphology (cloudy with soft contour) was most frequently associated with rotator cuff tears and demonstrated an increased odds of tear by a factor of 1.8 (CI\n                      <jats:sub>95%<\/jats:sub>\n                      1.1\u20102.9).There was no statistical difference regarding calcification size or location prognosticating rotator cuff tears or tear thickness.

Specific locations or sizes of calcified lesions do not appear to be reliable factors to predict concomitant rotator cuff tears.
