[A correlative study of 108 cases of lumbar disc herniation (plain X-ray film, myelography and operative findings)].

This article presented the X-ray plain films and myelograms of 108 patients with lumbar disc herniation and comparative study was made with operative findings. The diagnostic accuracy was 92.8%. Hypertrophic changes with lipping at posterior margin of the vertebral body and narrowing of anterior part of disc space with widening of the posterior part were useful signs for localizing the herniated disc. The myelographic signs of pressure on dural sac and nerve roots were evaluated for its significance in localization of the lesion and differential diagnosis. The X-ray manifestations of L S1 herniation were described in detail.
