[Intermittent Claudication Secondary to Spine and/or Spinal Cord Diseases].

Currently, intermittent claudication is classified into the vascular (mainly secondary to peripheral arterial disease) and neurogenic (mainly secondary to lumbar canal stenosis) types. Intermittent claudication due to spinovascular insufficiency (myelopathy) has rarely been reported since it was first described by J. Dejerine in 1894. However, currently, intrinsic (vascular diseases of the spinal cord) and extrinsic (disorders causing cervicothoracic cord compression) factors are implicated as contributors to this condition. No internationally accepted, transdisciplinary and standardized definition, technical terminology, and classification of intermittent claudication are currently available. I propose a new classification in this article. I have focused on intermittent claudication secondary to spine and/or spinal cord diseases, with regard to its epidemiology, symptomatology, and differential diagnosis.
