Sonography of the normal elbow.

Sonography was performed in 30 normal patients, neonatal to 45 years old, to illustrate our technique for complete and rapid examination of the elbow joint. Sonography is an easy, noninvasive method of evaluating the articulating surfaces, tendinous insertions, and supporting soft tissues of the elbow joint. Reliable identification of both normal and diseased anatomy is possible at all ages. Familiarization with the sonographic appearance of the six elbow ossification centers aids in sonographic interpretation.
