Unusual compressive neuropathies of the upper limb.

Compression neuropathies are one of the most common causes of upper extremity pain. This article has addressed the diagnosis and treatment of some of the more unusual neuropathies. As always, a thorough knowledge of anatomy and its valuation, and a careful and impulsive physical examination will guide the clinician to the appropriate diagnosis. Electrical studies, done carefully and with the clinical diagnosis as a label, will often be confirmatory. In cases not responsive to nonoperative measures, surgery to decompress the nerve and to restore missing function will usually proved a modicum of patient improvement.
