[Diagnostic brought in lomboradicular pain in the lower limbs].

Diagnostic brought in lomboradicular pain in the lower limbs. Lower limbs radicular pain are frequent. Most of them are caused by lumbar disc herniation or osteoarthritis spinal stenosis. Interrogation and clinical examination are the key stages of the diagnosis, allowing to detect signs of gravity and to rule out the differential diagnosis. The progress of radiological technics, in particular the MRI, considerably simplified the diagnostic approach, but require confronting, with a rigorous objectivity, imaging with the clinical data. The diagnostic approach has to answer two questions: does the symptoms correspond to a common lomboradicular pain or to an other explanation, tumoral for example? In case of common lomboradicular pain, is it a disc herniation, osteoarthritis, or lumbar spinal stenosis?
