Abstract

Partial paralysis of the posterior interosseous nerve at the forearm region has been rarely reported. We report our patients. After closed crushing injury at the forearm region, the patients showed "Sign of horns" which means disability of extension at the third and fourth metacarpo-phalangeal joint because of partial paralysis of the posterior interosseous nerve. We treated the patients as conservative treatment and the patients was completely recovered. So the autors report this case.

Keywords: Posterior interosseous nerve, Closed crushing injury
