抄録

The defects created by the anterior margin of the glenoid in the posterolateral area of the humeral head has been recognized as the dislocation of the shoulder joint. It was well known as the Hill-Sachs notch and was regarded as one of the reasons for recurrent dislocation of the shoulder joint. The defects in the humeral head were demonstrated by internal rotation and Stryker's notch viewer, radiographicaly. Orthographic projections were performed on 15 cases of recurrent dislocation of the shoulder. The patient is supine on the table with a cassette under his shoulder, the humerus is positioned at 135 degrees forward elevation and 15 degrees internal rotation. Without tilting the X-ray beam, it is centered over the humeral head.<BR>The posterolateral notches were positive in 59% of the cases using Stryker's notch viewer, but 88% of the cases were positive using the orthographic projection technique. The orthographic projection was useful in observing the posterolateral notch, because of its high recognition rate. Furthermore, there is no distortion on X-rays and the quantitative analysis of the notches are superior.
