Abstract

We report 2 patients with nerve palsy caused by hourglass-like constriction. One patient with paralysis of flexor pollicis longus and intact 2nd flexor digitorum profundus was found to have non-traumatic multiple fascicular torsions within main trunk of median nerve after epineurotomy. He was managed by nerve reconstruction using medial antebrachial cutaneous nerve graft and fully recovered the function of flexor pollicis longus. The other patient presented with palsy of muscles innervated by posterior interosseous nerve. We also explored and had nerve reconstruction using sural nerve graft. He partially recovered the function of posterior interosseous innervated muscles.
