Compressive neuropathies of the elbow

The major peripheral nerves supplying motor and sensory function to the forearm and hand traverse the elbow joint. The complex anatomical relationships of these nerves to the joint and its surrounding musculotendinous structures creates a series of sites where these nerves are vulnerable to compression. Compression syndromes result in distressing constellations of pain, paraesthesia, weakness and loss of coordinated motor function. This article discusses the anatomy and pathophysiology of compressive neuropathies around the elbow joint, their presentation, how they are investigated and diagnosed, and the available management options.
