Spinographic measurements on lateral lumbar radiographs are numerous and have much clinical significance. The present study is aiming to qualify the clinical significance of McNabbs line in which the inferior endplate line is extended posteriorly. The line is deemed positive if the superior articular facet of the vertebra below extends above this line thus representing a segmental hyperextension.
The present study will objectively compare the results of McNabbs line drawn onto exisiting x-rays with the corresponding patients complaints. That is back pain, pain in the lower limb and paresthesia in the lower limb. Since the x-rays to be used are taken erect this contrasts with McNabbs studies in which x-rays taken in the recumbent position were used, thus rendering the disc and posterior spinal elements non-weightbearing. The study will attempt to reveal if a relationship exists between McNabbs line and the clinical condition of the patient, if McNabbs line holds any value as a diagnostic tool, and if McNabbs line is a useful measurement to be used as an adjunct to measuring the intervertebral disc space in assessing the condition of the disc.
