MR features of nerve disorders at the elbow.
MR imaging is a useful method for evaluating nerve disease. It can portray the normal anatomy and identify unsuspected space-occupying masses. Severe intrinsic nerve disease can be depicted. This article outlines the normal anatomy of the three major nerves that traverse the elbow joint: the ulnar nerve, the median nerve, and the radial nerve. Entrapment and compression neuropathies of each nerve are discussed in detail. Finally, the role of MR imaging in delineating each nerve abnormality is examined.
