Complete rupture of the supraspinatus tendon is not only a relatively common lesion but an extremely painful one. In spite of this, the diagnosis is seldom made and the condition suffers from general neglect. Several instances will be cited in proof of this statement. In May 1943, a study was made of the records of a fine orthopedic clinic. These records covered fifteen years, and in them were listed six hundred and fifty varied types of painful shoulders. The diagnosis of complete rupture of the supraspinatus tendon was not made in a single case. This finding aroused great curiosity, and as a result personal conversations were held with twenty leading orthopedic surgeons in the middle and far west in the eight months that followed. Without a single exception, they readily admitted never having made the diagnosis of complete rupture, and consequently they had never seen or repaired such a rupture.
