Guyon's canal syndrome is caused by entrapment of the ulnar nerve in Guyon canal at wrist. Conservative and surgical approaches are used for treatment of Guyon’s canal syndrome, but the effect of conventional treatments is questionable. The purpose of this study is to show the effect of extracorporeal shock wave therapy (ESWT) as a new strategy of Guyon's canal syndrome. ESWT was applied to four patients, who diagnosed with Guyon’s canal syndrome, twice a week for 6 weeks, 500 shocks, 4 Hz, 0.08 mJ/mm2. The outcome measurement was including the visual analog scale (VAS), QuickDASH scale electrophysiologic study, which performed before treatment, after treatment and 6 month after treatment. The 4 patients were showed improvement of clinical parameter and electrophysiologic parameter. Conclusively, ESWT may be a useful conservative method for treating Guyon's canal syndrome.
