Elbow arthrography.

Arthrography of the elbow is performed infrequently, but may be quite useful in demonstrating the presence, number, and location of intra-articular loose bodies, and in evaluating articular cartilaginous surfaces. Such information may be valuable in the selection of an operative versus a nonoperative course of treatment, and, if surgery is elected, it may be useful to the surgeon in planning the operative approach and in locating the position of all of the abnormalities present. Elbow arthrography is also of occasional value in demonstrating synovial disease, evaluating certain traumatic disorders, and verifying needle position during aspiration. A useful and accurate elbow arthrogram requires careful planning and may require considerable time to perform completely. Plain radiographs should be carefully examined. Fluoroscopic observation before injection may be extremely helpful, and thoughtful selection of the type and amount of contrast medium is necessary. Adequate arthrographic films may be obtained only after careful consideration of the abnormalities to be demonstrated and their location in the joint. Tomography is almost always necessary for a thorough evaluation.
