Spinal disorders are often confusing when first presented to the clinician. Unfortunately, too much reliance is placed upon radiographic examination. A thorough neurological examination should not be neglected. Such an examination can be rapidly performed, and is inexpensive. Proper radiological interpretation depends upon the central beam being directed through the area of the lesion as determined by the neurological examination.
