A case of thenar numbness, with concomitant carpal tunnel syndrome is presented. Physical
findings and the result of injection of a local anesthetic into two different sites
of tenderness suggested coexistence of entrapment and/or compression of the palmar
cutaneous branch of the median nerve and the main trunk of the median nerve at the
carpal tunnel. At operation, constriction of the palmar cutaneous branch of the median
nerve by the fascia of seemingly normal flexor digitorum superficialis was observed
beneath the site of maximum tenderness. After decompression of this nerve, combined
with carpal tunnel release, the patient lost all pain and numbness; there was no recurrence
at 5 months follow-up.
