Abstract
The double compression syndrome of the ulnar nerve is a rare condition. Herin, we experienced double compression of ulnar nerve at cubital tunnel and Guyon’s canal by re-evaluation after surgical decompression of cubital tunnel. We might suspect the double compression lesion in cases of worsening of symptom or nerve conduction velocity findings in a relative short duration of symptom as in our case. Meticulous physical examination might be needed to detect the Guyon’s canal syndrome as a comorbidity in the treatment of cubital tunnel syndrome and re-evaluation for dual compression might be recommended if the resolution of symptom was not achieved after surgical decompression of single nerve lesion.
