[Clinical review of thirty-nine cases of ulnar tunnel syndrome].
OBJECTIVE
To discuss the concept of ulnar tunnel at the wrist, the types, causes, traits of compression, diagnosis, and clinical significance of ulnar tunnel syndrome (UTS).


METHODS
Thirty-nine cases diagnosed as having UTS from 1986 were retrospectively reviewed combined with previous relevant literature.


RESULTS
Ulnar tunnel included Guyon's canal, piso-hamate tunnel and hypothenar segment. There were 8 types and many causes of UTS. Some patients had compression in more than one zones and might be associated with carpal tunnel syndrome or cubital tunnel syndrome. UTS could be diagnosed through clinical manifestations and electrophysiological examination.


CONCLUSIONS
Defining the concept of ulnar tunnel and the knowledge of the complexity and rarity of UTS can effectively guide diagnosis and treatment.
