Objective: To assess the causes and the ulnar nerve compression areas in Guyon’s canal.
Material and method: A retrospective study, with a mean follow-up of 9 months, was conducted on 12 patients intervened due to cubital tunnel syndrome. An electrophysiological study was performed on all cases and it was observed if there was a relationship with the presence of carpal tunnel syndrome.
Results: A clear origin of the nerve compression was only found in 3 cases. There is a higher presence of carpal tunnel syndrome in those cases of with idiopathic ulnar nerve compression, but it is not statistically significant.
Conclusions: In our experience, the majority of ulnar nerve compressions in the wrist are of idiopathic origin. There is a clinical improvement of the symptoms with surgery.
