✓ The authors report their experience with 12 cases in which the roots of the sciatic nerve were compressed at the intervertebral foramina by degenerative arthritis (arthrosis) of the posterior facets, and in which foraminotomy and facetectomy brought relief of pain. Patients with disc narrowing, spondylolisthesis, and transitional vertebrae place unusual stress on the posterior facets. This may lead to hypertrophy and the development of marginal osteophytes that project downward with eventual constriction of the intervertebral foramen and entrapment of the nerve root. Such alterations are common in patients over 40, and when found in the presence of unremitting sciatic pain without evidence of a herniated disc or other etiology, a causal relationship must be considered.

✓ Synovial cysts of the ligamentum flavum, measuring 1 cm in diameter, caused compression of the lumbar nerve roots in four patients. The authors discuss the association of these cysts with advanced focal spondylosis, and speculate on their etiology.

Bladder Evaluation

✓ One hundred patients with the provisional diagnosis of nerve root compression in the lumbar spine were subjected to routine bladder evaluation by cystometry in addition to the standard somatic neurological examination. Eighty-three were found to have cystometrograms characteristic of bladder hypofunction. Residual urine was found in 20% of the 100 patients. By contrast, the examination of the somatic nervous system disclosed sensory deficits in 36%, weakness in 59%, reflex alterations in 66%, and positive sciatic-stretch tests in 69%. Almost all cystometric studies (96%) became normal after successful surgical or conservative therapy. It is concluded that occult bladder dysfunction is a major manifestation of lumbar nerve root compression. The neurophysiological mechanisms involved are discussed in detail.

Epidural Gas

✓ Extreme lateral disc herniations are increasingly recognized as a cause of lumbar nerve root compression syndromes. This disorder often presents major diagnostic and therapeutic challenges, especially in the presence of multiple degenerative changes and chronic back pain in elderly patients. The authors describe two patients with presentations and findings that have not been previously described in the literature. Both patients had histories of upper lumbar back and leg pain. Degenerative spine disease, gaseous degeneration of the intervertebral discs, and epidural gas in the lateral recesses were noted on imaging studies. However, because both patients had undergone prior epidural diagnostic and therapeutic procedures, the epidural gas in the lateral recesses could be attributed either to gaseous disc degeneration or to the previous intraspinal procedures. One patient was found to have a large, far lateral extruded disc fragment that contained air. The nerve root in the second patient was impaled by an unusual combination of a small extruded disc fragment as well as an air-filled sac that was surrounded by the walled-off fragment's capsule and which freely communicated with the gaseous degenerated disc space. The suspected mechanism of root compression is illustrated and discussed. The possibility of disc herniation should be seriously considered in cases of nerve root compression in which epidural gas is present, especially those associated with gaseous degenerated discs.
