Zusammenfassung:Paralysis or nerve injury associated with fractures of forearm bones fracture is rare and is more common in exposed fractures with large soft-tissue injuries. Ulnar nerve paralysis is a rare condition associated with closed fractures of the forearm. In most cases, the cause of paralysis is nerve contusion, which evolves with neuropraxia. However, nerve lacerations and entrapment at the fracture site always need to be borne in mind. This becomes more important when neuropraxia appears or worsens after reduction of a closed fracture of the forearm has been completed. The importance of diagnosing this injury and differentiating its features lies in the fact that, depending on the type of lesion, different types of management will be chosen. A paralisia ou lesão nervosa associada à fratura dos ossos do antebraço é rara, é mais comum nas fraturas expostas com grande lesão de partes moles. A paralisia do nervo ulnar é uma condição incomum associada a fraturas fechadas do antebraço. Na grande maioria dos casos, a causa da paralisia é a contusão do nervo, que evolui com neuropraxia. No entanto, devemos sempre estar atentos às lacerações do nervo e ao encarceramento do nervo no foco de fratura. Isso se torna mais importante quando ocorre o surgimento da neuropraxia ou pioria após a feitura da redução da fratura fechada do antebraço. A importância do diagnóstico da lesão e diferenciar suas características estão no fato de que, conforme o tipo de lesão, diferentes tipos de manejo serão escolhidos.
