title: Posterior interosseous nerve paralysis related to focal radial nerve constriction secondary to vasculitis.
abstract: A case of posterior interosseous nerve paralysis is reported with discussion of some characteristics that appear to distinguish it from entrapment neuropathy and neuralgic amyotrophy. The surgical implications are also discussed. More than ten similar cases have been reported, but the pathogenesis of this condition is still controversial. The patient presented with posterior interosseous nerve paralysis related to focal radial nerve constriction secondary to vasculitis in the perineurium. The constriction site was resected and the radial nerve was sutured. The patient recovered completely after 8 months.
