Disfunción del nervio cubital - Overview

Nombres alternativos

Neuropatía del nervio cubital; Parálisis del nervio cubital

Definición:

Es un problema con el nervio cubital, el cual va desde el hombro hasta la mano y permite el movimiento o la sensibilidad en la muñeca y la mano.

Causas, incidencia y factores de riesgo:

El daño a un grupo de nervios, como el nervio cubital, se denomina mononeuropatía. Mononeuropatía significa que hay daño a un solo grupo de nervios. Los trastornos tanto locales como generalizados pueden causarle daño sólo a un nervio.

Las causas usuales de mononeuropatía son:

  • Una enfermedad en todo el cuerpo que daña a un solo nervio
  • Lesión directa a un nervio
  • Presión prolongada sobre el nervio
  • Presión sobre el nervio provocada por inflamación o lesión de estructuras corporales cercanas

La neuropatía cubital ocurre cuando hay daño al nervio cubital, el cual baja por todo el brazo. Este nervio está cerca de la superficie del cuerpo cuando pasa por el codo. El daño destruye la cubierta del nervio (vaina de mielina) o de parte del nervio (axón) y retrasa o impide el envío de señales nerviosas.

El daño al nervio cubital puede ser causado por:

El dolor temporal y el hormigueo de este nervio puede ocurrir si se golpea el codo, produciendo la experiencia de golpear el "hueso de la risa" a la altura de esta articulación.

Una presión prolongada sobre la base de la palma de la mano también puede dañar parte del nervio cubital.

En algunos casos, no se puede identificar ninguna causa.
