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.

Surgical decompression of cubital tunnel and subcutaneous ulnar nerve anterior transposition were performed. Focal mild swelling of the ulnar nerve was observed (white arrow).

Guyon’s canal decompression with excision of the ganglion and carpal tunnel release. (A) Ganglion was observed on the pisotriquetral ligament. (B) After excision of the ganglion, the capsule was opened. (C) Carpal tunnel release was also performed with Guyon’s canal release.
