[Ultrasound imaging of the elbow joint. Loose joint bodies and osteochondrosis dissecans].

In 6 patients with loose bodies due to osteochondritis dissecans, trauma or chondromatosis at the elbow, an additional ultrasonic examination was performed. In all cases loose bodies as well as the osteochondral lesion at the radial head and trochlea humeri were seen. Ultrasonic examination of the elbow is recommended in addition to the mandatory x-ray examination. However, sonography enables reduction of x-ray exposure because additional x-ray tomography can be avoided.
