Atypical compression of the deep branch of the ulnar nerve in Guyon's canal by a ganglion. Case report.
A 61-year-old woman with an ulnar claw-finger deformity but no sensory loss had a cystic lesion excised from Guyon's canal. The ganglion was in zone 1 of the canal, which is associated with both motor and sensory deficit, but on this occasion it caused motor dysfunction alone.
