✓ This study was designed to investigate neural mechanisms of referred pain in lumbar intervertebral disc lesions. Patients with a degenerative disc in lower lumbar segments occasionally complain of groin pain, which cannot be explained anatomically as having a radicular origin. In rats pretreated with intravenous application of Evans blue dye, the dye extravasation appeared in the groin skin after application of capsaicin to the ventral portion of the L5–6 intervertebral disc. This response occurred even in rats with a sectioned L-5 spinal nerve and sympathetic trunks, but did not occur in rats with a sectioned genitofemoral nerve. Capsaicin topically applied to the sciatic nerve did not cause dye extravasation in the hindpaw. Therefore, groin dye extravasation was not due to a direct effect of capsaicin but, rather, presumably was caused by an “antidromic axon reflex” of dichotomizing C fibers or to a segmental sympathetic reflex causing vascular permeability. The present results indicate that the ventral portion of the lumbar discs is neurally connected to the groin skin via the upper (L-2) lumbar spinal nerves in rats. Groin pain coincident with low-back pain may be explained as referred pain, indicating that a lesion is present in the ventral portion of the lumbar intervertebral disc space.

✓ The case of a 13-year-old boy with a gelatinous, herniated lumbar intervertebral disc is reported. Roentgenographic examination 8 years following laminectomy demonstrated spondylolysis and spondylolisthesis of L-5 on S-1. Related case reports and theories are tabulated and discussed.

✓ The authors describe a technique whereby a portion of the lamina removed during exposure of an intervertebral lumbar disc protrusion is implanted in the intervertebral disc space following disc excision. An analysis of 456 consecutive cases operated on by this technique and followed from 1 to 10 years is presented. Of the 418 patients followed, 92% indicated they were able to return to their normal activities and were satisfied with the result. Thirty percent of the patients indicated they had required some conservative treatment for recurrent episodes of back or leg pain. Ten patients had subsequent back surgery; only one implant has dislocated.

✓ A case of retroperitoneal vascular injury during removal of a lumbar intervertebral disc is presented. It is proposed that the rapid escape of irrigating saline through the disc space may serve as a reliable sign of surgical perforation of the anterior annulus and anterior longitudinal ligament prior to the appearance of other signs of vascular injury.

✓ Chymopapain chemonucleolysis was performed on 100 patients with primary lumbar intervertebral disc disease. The results were compared with those of 174 patients who underwent laminotomy, foraminotomy, and discectomy. Primary lumbar intervertebral disc disease was arbitrarily divided into degenerative, complex, previous surgical, and simple disc syndromes. No difference was seen between chemonucleolysis and surgery in the first three divisions; between 55% and 60% of patients responded successfully to treatment. In the simple disc division 89% of the surgical and 60% of the chemonucleolysis patients had successful results.

✓ Three teenagers operated on for suspected rupture of a lumbar intervertebral disc are presented. The finding at surgery in each case was a bony, cartilaginous, and nucleus pulposus ridge crossing the anterior spinal canal. Since the bony epiphyseal ring or apophysis is said to be deficient posteriorly, these patients presumably had a dislocation of an anomalous epiphyseal ring.

✓ Thirty-three intervertebral disc patients who otherwise would have been subjected to surgery were treated by injection with chymopapain. The pharmacology, toxicology, physiology, immunology, and chemical action of this enzyme, which specifically reacts with chondromucoproteins, are discussed. Results indicate that this method, although still experimental and unapproved by the U. S. Food and Drug Administration, may become a useful addition to the surgeon's armamentarium in the treatment of intervertebral disc disease.

Rapid Conversion

✓ In the first of a two-part study, the authors review the known biochemical, pharmacological, toxicological, and experimental data concerning chymopapain and the intervertebral disc. They describe the action of this proteolytic enzyme, which apparently disrupts the protein mucopolysaccharide component of disc material, most marked in the nucleus pulposus. A rapid conversion to collagen causes a loss of disc space height; toxicity appears to result from alteration of bonding between capillary endothelial cells that in turn produces hemorrhage. Part 2 reviews significant reported results and complications of clinical chemonucleolysis.
