Abstract

We applied our own standardized CT procedure to scan the wrists of 50 subjects with irritation and/or deficit in the ulnar nerve. The direct and indirect causes of nerve compression were identified in 43 cases and divided into 4 disease groups: I) Intra or extracanal cysts; II) Calcification of the ulnar artery; III) Deformation of the small canal; IV) No CT distinction between nerve and artery. Deformation of the small canal was in turn caused by different factors such as degeneration of the carpal bone following rheumatoid arthritis, trauma, surgery for carpal syndrome and syndrome of the carpal canal. Fifteen patients underwent surgery which disclosed that failure to distinguish ulnar artery and nerve at CT was due to fibrosis of the paranerve with reduced connective tissue and fibrous laces between nerve and artery. Guyon's syndrome, carpal syndrome and so-called synovial cysts were frequently associated and seem to confirm a common degenerative origin in cases not resulting from external indirect causes. CT remains the cheapest most complete imaging procedure for diagnosis of wrist canal syndromes.
