title: [Sonographic determination of the humerus retrotorsion angle].
abstract: In patients with habitual dislocation of the shoulder and post-fracture malrotation the measurement of humeral torsion is important in preoperative diagnostics. An easy method of ultrasonic measurement of humeral torsion is proposed. The correlation with anthropometric, radiological and CT-measurement is good, what could be shown in 20 macerated humeri. In 111 patients with normal glenohumeral joints the average of humeral retrotorsion was 61 degrees. 86% had a torsion between 40 and 80 degrees.
