Disfunción del nervio femoral - Symptom

Nombres alternativos

Neuropatía del nervio femoral; Neuropatía femoral

Síntomas:

  • Cambios en la sensibilidad del muslo, rodilla o pierna tales como disminución de la sensibilidad, entumecimiento, hormigueo, ardor, sensación de que "la rodilla se sale" o se dobla, o (poco común) dolor.
  • Debilidad de la rodilla o la pierna, incluyendo dificultad para subir y bajar peldaños, especialmente esto último.

Signos y exámenes:

Un examen de nervios y músculos (examen neuromuscular) de las piernas muestra que el nervio femoral no está trabajando bien. Usted podría tener debilidad al extender la rodilla o al doblarse a la altura de la cadera. Los cambios de sensibilidad se localizan en la parte superior frontal del muslo y la pantorrilla interior. El reflejo rotuliano puede disminuir o estar ausente. Los músculos cuadríceps de la parte frontal del muslo pueden estar más pequeños de lo normal.

Los exámenes que revelan disfunción del nervio femoral pueden abarcar:

  • Electromiografía (EMG)
  • Pruebas de conducción nerviosa ( VCN que por lo general se hace al mismo tiempo que una EMG)
  • Resonancia magnética para buscar masas o tejido anormal (lesiones)

Los exámenes se realizarán de acuerdo con la presunta causa del problema, para lo cual el médico tomará como base su historia clínica, los síntomas y el patrón de desarrollo de dichos síntomas. Estos exámenes pueden abarcar diversas pruebas de sangre, radiografías, gammagrafías u otros exámenes.
