Occult fractures of the greater tuberosity of the humerus: radiographic and MR imaging findings.

Abstract

The purpose of this study is to discuss the clinical implications of diagnosing a one-part greater tuberosity fracture on radiography and to describe associated rotator cuff findings on MR imaging. One-part greater tuberosity fractures are traditionally treated conservatively. Because clinical findings simulate those of rotator cuff abnormalities, some patients with missed or nonvisible fractures may be referred for MR imaging for further examination. In our study, MR imaging revealed no associated cuff abnormalities that required early surgery. Diagnosis of such a fracture on radiography may obviate the need for unnecessary MR imaging and arthroscopic surgery.
