Introduction
Ulnar nerve compression is the second most common cause of upper extremity neuropathy after carpal tunnel syndrome (Oswald 1998). Excluding compression at the cervical spine and brachial plexus, the literature describes many sites of compression along the nerve (Contreras 1998, Jones 1991, Khoo 1996, Nuber 1998, Oswald 1998). When diagnosing an ulnar nerve neuropathy the four most common anatomical sites of compression that should be considered are: the Arcade of Struthers, the retrocondylar groove, cubital tunnel and Guyon's canal (Khoo 1996).
