This paper describes the use of ultrasound in the evaluation of the elbow. Ultrasound has emerged as a useful imaging method for the diagnosis of joint and soft tissue pathology. The elbow is easily amenable to ultrasound examination due to its superficial position. Ultrasound is able to assess various abnormalities of the elbow affecting tendons, muscles, ligaments and bursa around the elbow as well as to define the nature of soft-tissue swelling, such as a space- occupying lesion or synovial enlargement. Intra-articular loose bodies and occult fracture can be delineated with this method as well. At the cubital tunnel, ultrasound allows accurate imaging of the ulnar nerve and proves changes that occur in compressive syndromes. It is likely that the use of ultrasound will increase further concerning evaluation of the wide range of disorders of the elbow. (J Korean Assoc Pain Med 2008;7:90-96)
