Abstract
The development of high resolution ultrasound has allowed evaluation of normal and abnormal ultrasound appearance of the ulnar nerve. Ultrasound provides a unique method for evaluation of the ulnar nerve at the elbow because it allows direct imaging of nerve as well as changes in nerve shape, size, echo texture and position during dynamic sonographic study of the nerve. The high resolution dynamic ultrasound helps in evaluation of the ulnar nerve during the extension and different degrees of elbow flexion. It has the ability to follow nerve over a long distance in a limb. The color and power Doppler improve the ability to evaluate the nerve by evaluation of nearby vessel. Entrapment neuropathy of the ulnar nerve at elbow is a disorder results from injury to a nerve as it travels through cubital osteofibrous tunnel. Ultrasound provides a unique opportunity for cliniciants to discover anatomic correlation for clinical and electrophysiological findings in patients with nerve entrapment. The US proved efficacy both as a first-line and in the follow-up period. US revealed morphological information about the exact location, intensity and extent of nerve entrapment
