The new edition of this book provides the current information on the diagnostic techniques and therapeutic approaches that will help clinicians optimize care for patients with intervertebral disk disease. The book covers the full range of problems frequently encountered in the clinical setting, including traumatic injuries, non-degenerative disk-diseases, and the numerous clinical syndromes of the cervical, thoracic, and lumbar spine.
For each syndrome, the book provides the definition and prevalence, anatomy, biomechanics, pathological anatomy and pathophysiology, clinical presentation, and the conservative and surgical treatment options.
Features of the third edition:
- New information on the biomechanics of the spine, pain management recent advances in spinal injection techniques, and microsurgical treatment of lumbar disk herniation
- More than 560 high-quality illustrations and images, including MRIs, demonstrating key concepts
- In-depth coverage of essential background information for management, rehabilitation, and preventive treatment

History
Spinal degenerative changes and intervertebral disk diseases are as old as humanity itself. Skeletal remains from all periods, from the era of early humans to modern times, yield plentiful evidence of damage to the vertebral column by wear and tear. Even though intervertebral disk diseases and the related pains in the shoulders, neck, low back, and lower limb are now quite common and are often held to be “diseases of civilization,” it turns out that our remote forebears suffered from them as well. Nor can it be said that the high prevalence of these conditions merely reflects today's longer life expectancy, because they often affect relatively young people.
It is remarkable that the syndrome of lumbar disk prolapse with sciatica, despite its clear-cut constellation of pathoanatomical and clinical neurological findings, was not fully understood until Mixter and Barr' seminal publication of 1934.
Decades before Mixter and Barr, anatomical dissection methods and surgical technique had advanced to the point that their discovery could easily have been anticipated. Indeed, some of the major medical writers of the ancient world and the Middle Ages had already surmised that the cause of sciatica lay in the intervertebral disk (Table 2.1).

Pre-Christian Times
Hippocrates (460–437 BC), for example, described a patient with pain in the hip, lower portion of the sacrum, and buttock, radiating into the leg. His treatment consisted, among other things, of baths and warm compresses, both of which are still in use today (Hippocrates 1897).
AD 1–1700
Galen of Pergamon (AD 128–199) held that certain aspects of the patient's lifestyle, such as sexual excess, over-consumption of wine, and idleness, were major contributing causes of sciatica. His treatment consisted in purification of the body, e. g., by bloodletting.
There were no major advances in the understanding of intervertebral disk disease for many centuries thereafter, notwithstanding the first precise description of the intervertebral disk by Vesalius in 1543 (see References) and the description of lumbago by Sydenham (1624–1689).
1700–1900
It was not until 1764 that Cotugno (1736–1822) published the first comprehensive work dealing with sciatica, De ischiade nervosa commentarius (“remarks on nervous sciatica”). His observations regarding diagnosis and treatment advanced the understanding of this condition so greatly that it came to be known in medical circles as “malum Cotunii”—Cotugno disease. The decades that followed saw further advances by others whose names are connected with clinical tests that are still in use today. The pressure points along the course of the sciatic nerve that were described by Valleix in 1852 are still known by his name, even though they had already been precisely described by Bretschneider 5 years earlier. One searches in vain for the sciatic nerve stretch test, the so-called “Lasègue test,” in Considérations sur la sciatique, Lasègue's magnum opus of 1864; it was first described in writing in 1881 by Lasègue's former student, Forst (cited in Finneson 1980).
The markedly abnormal posture of the trunk that accompanies sciatica due to disk prolapse was presumably known to physicians of earlier centuries but was first correctly described in 1888 by Charcot, the pioneer neurologist of Paris.
From 1900 Onward
Even though Charcot had already associated sciatica with a problem in the lumbar spine, the crucial observation that intervertebral disk lesions could cause cauda equina compression and sciatica was first made decades later by Krause and Oppenheim (1909) and by Goldthwait (1911). No further studies on the subject were made right away; it took 20 years for others to become convinced of the correctness of Goldthwait's idea by corroborating it in their own, larger series of patients. The decisive factor was the development of radiological studies involving the intraspinal injection of contrast substances—first air, as used by Dandy (1919), and then lipiodol, as used by Sicard and Forestier (1922). Regrettably, the pathologist Schmorl, who published his systematic study of the spine in 1928, lacked contact with clinicians who treated patients suffering from low back pain and sciatica. Otherwise, he and his co-workers would surely have grasped the clinical importance of their many discoveries. He described protuberances from the surface of the vertebral body (osteophytes), narrowing of the intervertebral disk, destruction of the anulus fibrosus, and displacement of disk tissue into the spongiosa of the vertebral body in what are now called Schmorl's nodes.
Finally, the seminal paper on intervertebral disk disease was published in 1934 by Mixter and Barr, who clearly described the production of sciatica by lumbar disk herniation and demonstrated the effectiveness of surgical treatment in 58 patients. Further improvements in the diagnosis and treatment of lumbar disk herniation came in the following years and decades.
The improved understanding of the etiology and pathogenesis of lumbar disk syndromes led to comparable advances in the cervical spine. Bärtschi-Rochaix, in 1949, described the causation of shoulder-arm syndrome and of pains in the nuchal region and occiput by loosening and displacement of the cervical intervertebral disks.
This recognition of the mechanically induced degenerative changes of the intervertebral disk as the major pathogenetic factor in disk disease was followed, in the ensuing decades, by further study of the biomechanical and biochemical properties of the disk. Junghanns (1951) brought about a significant advance by identifying the motion segment as the functional unit of the spine.
The introduction and further refinement of magnetic resonance imaging (MRI; Lauterbur and Mansfield 1973) was a major advance in the radiological...
