Calcific tendinitis of the rotator cuff with trochiteal osteolysis. A rare clinical radiologic complication.

Among cases of calcific tendinitis that are unresponsive to any type of non-surgical treatment, the authors report 3 cases, out of a total of 32 submitted to surgery, that presented with an osteolytic cavity filled with calcium salts in the insertional region of the supraspinous tendon. These patients presented with pain that they had been experiencing for an average of 4 years, with acute recurrent episodes. When this pathology can be determined radiographically, early surgery is recommended, considering that any type of non-surgical treatment is destined to fail.
