Second, the x-ray discogram should be more clearly illustrated since its interpretation could then be more readily understood and coordinated with the clinical picture of low-back pain. The material for this report is based on experiences while working with Feffer.5,6 There is a need for a more accurate method of diagnosis of intervertebral disc pathology.
