Elbow joint: assessment with double-contrast CT arthrography.

The elbow joint was evaluated by means of computed tomography (CT) immediately following double-contrast arthrography. Normal baseline anatomy and representative abnormal studies are illustrated. Intraarticular abnormalities, such as osteocartilaginous bodies, hyperplastic synovium, fracture fragments, and osteophytes, were identified and precisely located on postarthrography CT scans. This technique, which enabled such abnormalities to be seen, has provided an anatomic and mechanical basis for seemingly idiopathic instances of limited elbow motion.
