Radial Nerve Compression

The radial nerve is also known as the “great extensor nerve” due to its innervation of the triceps, wrist and finger extensors. It originates from the posterior cord of the brachial plexus, and its course along the proximal humerus makes it particularly vulnerable to injury by compression at the proximal arm. In the primary care setting, radial neuropathy is the third most common compressive neuropathy syndrome of the peripheral nerves. “Crutch palsy” occurs when improper use or fitting of crutches causes prolonged compression of the radial nerve at the axilla. Bilateral radial nerve compression due to axillary crutches is a relatively rare entity with few well documented cases in the literature. Crutch palsy occurs from improper use of crutches causing prolonged compression of radial nerve. Proper fitting and education on correct usage of crutches may prevent this complication. A thorough history, physical exam and electrodiagnostic study are helpful in the diagnosis and prognosis of the illness. Radial compression neuropathy may be caused by extrinsic or intrinsic compression, and can occur at various locations along the course of the radial nerve.
