Cruciate paralysis secondary to traumatic atlantooccipital dislocation.

Abstract

Cruciate paralysis is a clinical phenomenon thought to result from injury to decussating pyramidal tract fibers at the cervicomedullary junction, producing clinical findings of upper-extremity weakness out of proportion to the lower extremities. The authors present, to their knowledge, the first reported case of cruciate paralysis resulting from atlantooccipital dislocation.
