<B>Background:</B> The purpose of this study was to report 6 cases of calcific tendinitis with osseous lesion of greater tuberosity.<BR><B>Methods:</B> In 6 shoulders, who had arthroscopic excision of calcium deposits in contact with greater tuberosity, the distribution of calcium deposits were examined by preoperative MRI images, CT images, and arthroscopic intraoperative views. Clinical results and postoperative MRI images were also evaluated.<BR><B>Results:</B> In 4 of 6 shoulders, the calcium deposits extended inside greater tuberosity were observed by the arthroscopic view. In 3 of these 4 shoulders, cortical erosion of greater tuberosity was observed on preoperative CT images. In 2 of these 4 shoulders, low intensity lesions on both T1 and T2 preoperative MRI images were detected inside of greater tuberosity. After removal of calcium deposits, clinical results, evaluated by JOA score, was significantly improved. The low intensity lesions inside greater tuberosity on both T1 and T2 preoperative MRI images were getting smaller, and the intensity of the intraosseous lesions was equal to adjacent rotator cuff tendon on postoperative MRI images.<BR><B>Discussion:</B> In the literature, although most of the calcific tendinitis of rotator cuff was well treated conservatively, calcific tendinitis with osseous involvement of greater tuberosity was less successful in conservative treatment. The sequence of osseous involvement was not elucidated. In this study, arthroscopic removal of the deposits improved JOA score and reduced osseous lesion of greater tuberosity on MRI images.
