Computed tomographic scanning and the lumbar spine. Part I: Economic and historic review.

Computed tomography represents one of the most remarkable short-term technical advances ever seen in medicine. Its recent extension to scanning of the lumbar spine promises to become its most significant extra-cranial application. The accusation has been made that CT scanning represents an expensive diagnostic modality whose cost is unjustified by its clinical value. Recent studies indicate that CT scanning is presently cost-effective and promises to become more so in the future, not only by decreasing the cost of instrumentation but also by replacing other diagnostic tests (particularly those of an invasive type) and lessening the need for exploratory surgery. CT scanning is of direct benefit to the patient because it assures that lumbar surgery is performed only after an accurate and complete diagnosis.

Computed tomographic scanning and the lumbar spine. Part II: Clinical considerations.

With the advent of computed tomography of the lumbar spine, the theories of a small number of pioneering physicians regarding the pathologic sequela of degenerative disc disease and the entities of central and lateral spinal stenosis have been translated into objective determinations which can now be observed by all. CT scanning has provided clinicians with a better appreciation of the diagnostic limitations of myelography and of the pathologic sequela of hemilaminectomy, dorsal-lateral fusion, and discectomy itself. Since the identification by CT scanning of the loss of disc volume, leading to lateral nerve entrapment and nerve compression resulting from fusion overgrowth, it has become clear that our present modes of therapy require comprehensive reevaluation. Because of the findings of CT scanning, dorsal-lateral fusion now appears to have a much reduced role in the treatment of degenerative disc disease and spinal stenosis. In an era in which unnecessary surgery is a matter of concern, CT scanning is an important means of ensuring that surgery will be undertaken only after thorough pathologic conditions.

Safety and clinical efficacy of implanted neuroaugmentive spinal devices for the relief of pain.

When applied under the circumstances of minimal patient risk, as documented in this paper, implanted neuroaugmentive spinal devices are a reasonable means of therapy for selected severe pain problems. With presently developed screening techniques, a 50% good-to-excellent result was obtained in 198 patients predominently consisting of 'failed back surgery syndrome' (94%). These figures represent a very significant improvement in success of treatment for this group of patients when compared to other present modes of therapy. With continued optimization of the use of spinal neuroaugmentive devices, it is likely that future clinical success can be significantly improved.

RF lesion generation.

Although the technique of RF lesion generation is a well-established medical technique, most professionals using it do not understand the basic principles of electronics by which the phenomenon occurs. A review of this with special attention to the 'indifferent' or 'dispersive' electrode would lead to better practice and less adverse effects, such as patient skin burns.

Percutaneous radiofrequency facet denervation.

Percutaneous RF facet denervation is a valid, low-risk means of treating 'mechanical' pain syndromes in previously unoperated patients with back and/or leg pain. In the series of 126 patients, reported long-term overall success was 42%. With improved technique and patient selection, success rate has increased to 67%. This procedure appears to be increasing in clinical value as a more conservative means of treating certain back pain problems, thus avoiding definitive surgery.
