This results in back pain and leg pain (lumbar herniation) or neck pain and arm pain (cervical herniation) due to nerve root irritation. Causes, incidence, and risk factors Return to top The bones of the spinal column, or vertebrae, run down the back connecting the skull to the pelvis. These bones protect nerves as they exit the brain and travel down the back and then to the entire body. The spinal column is divided into several segments the cervical spine (the neck), the thoracic spine (the part of the back behind the chest), the lumbar spine (lower back), and sacral spine (the part connected to the pelvis that does not move).

Extractions: Main Search Index Definition Description Causes ... Resources A herniated disk refers to the rupture of fibrocartilagenous material, called the annulus fibrosis, that surrounds the intervertebral disk. When this occurs, pressure from the vertebrae above and below may force the disk's center portion, a gel-like substance, outward, placing additional pressure on the spinal nerve and causing pain and damage. (Illustration by Electronic Illustrators Group.) Definition Disk herniation is a rupture of fibrocartilagenous material (annulus fibrosis) that surrounds the intervertebral disk. This rupture involves the release of the disk's center portion containing a gelatinous substance called the nucleus pulposus. Pressure from the vertebrae above and below may cause the nucleus pulposus to be forced outward, placing pressure on a spinal nerve and causing considerable pain and damage to the nerve. This condition most frequently occurs in the lumbar region and is also commonly called herniated nucleus pulposus, prolapsed disk, ruptured intervertebral disk, or slipped disk. Description The spinal column is made up of 26 vertebrae that are joined together and permit forward and backward bending, side bending, and rotation of the spine. Five distinct regions comprise the spinal column, including the cervical (neck) region, thoracic (chest) region, lumbar (low back) region, sacral and coccygeal (tailbone) region. The cervical region consists of seven vertebrae, the thoracic region includes 12 vertebrae, and the lumbar region contains five vertebrae. The sacrum is composed of five fused vertebrae, which are connected to four fused vertebrae forming the coccyx. Intervertebral disks lie between each adjacent vertebra.
Extractions: Disk degeneration is noticeable by the age of 20. The process consists of desiccation, or water loss in the nucleus pulposus and decreased tissue resiliency with decrease in the height of the disk space. With age, the initially soft and gelatinous nucleus pulposus is replaced by fibrocartilage and the distinction between nucleus pulposus and annulus fibrosis becomes less distance. The annulus becomes fissured and negative pressures bring nitrogen out of solution causing vacuum phenomenon. Disk height loss leads to malalignment and all of these processes permit disk material to bulge and subsequently herniate. The second finding in this patient was a conjoined nerve root sleeve. This is a congenital anomaly that is considered a normal variant and is found in 1-3% of the population. Pathology: The terminology of disk disease is at times muddy, however the following definitions are helpful: bulge: concentric smooth circumferential expansion of softened disk material beyond the confines of endplates. Protrusion = herniation: focal protrusion of disk material maintaining broad base with parent disk due to weakened or ruptured annulus fibrosus but intact posterior longitudinal ligament (herniation implies ruptured annulus fibrosus but protrusion doesn't necessarily). Extrusion: prominent focal extrusion of disk material with only an isthmus of connection with the parent disk due to ruptured annulus and intact or ruptured posterior longitudinal ligament. Free fragment: frank separation of disk material from parent disk (may migrate). There was no resected pathologic specimen from this patient.
Extractions: Acute Lumbar Disk Injuries in Active Patients Making Optimal Management Decisions Mathew W. Lively, DO; Julian E. Bailes, Jr, MD THE PHYSICIAN AND SPORTSMEDICINE - VOL 33 - NO. 4 - APRIL 2005 For CME accreditation information, instructions and learning objectives, click here In Brief: Managing acute lumbar disk herniations in active patients can be challenging for physicians, especially when controversies surrounding treatment options make choosing the right care more difficult. The prognosis for lumbar disk herniations is generally favorable, and most patients will improve with conservative measures, such as early activity and avoiding bed rest. Minimally invasive techniques, such as percutaneous diskectomy, laser diskectomy, and epidural corticosteroid injection, may help control sciatic pain. Athletes who sustain late-season disk injuries should receive conservative treatment before considering surgery. Those who have early-season injuries may be able to return to competition sooner by having a microdiskectomy before a full course of conservative therapy is completed, but data supporting this approach are currently lacking. T he incidence of low-back pain in college athletes ranges from 6.9% to 64.8%
Extractions: Andrew L. Chen, MD, MS; Jeffrey M. Spivak, MD THE PHYSICIAN AND SPORTSMEDICINE - VOL 31 - NO. 8 - AUGUST 2003 In Brief: Degenerative lumbar spinal stenosis commonly disables and functionally limits the aging population. Degenerative changes may constrict the spinal canal, lateral recesses, and neural foramina, compressing the neural elements. Clinicians can make an earlier, more accurate diagnosis by using advanced imaging techniques. Nonoperative management is the mainstay of treatment, although surgery is indicated in patients who have progressive neurologic decline or when nonoperative measures have failed to adequately address symptoms. I n the 1980s, the median age of the US population increased by 1.4 years, with an additional 2 million people age 65 or older. More people are maintaining active lifestyles as they age; consequently, symptomatic degenerative disease of the spine is often clinically significant and may result in functional debilitation. Lumbar spinal stenosis is characterized by narrowing of the spinal canal and/or the intervertebral foramina that decreases space for the neural elements. The condition may be secondary to congenital (developmental) or degenerative (acquired) causes.

Back pain is one of the leading reasons for office visits to primary care physicians and one of the most common diagnoses for nonsurgical hospital admissions in adults under 65 years of age. More than 75 percent of persons at some time in their lives have severe low back pain that requires medical attention, with an annual incidence of 7 to 15 percent. Medical expenses directly related to back pain total more than $8 billion per year. Disability payments and indirect expenses are more than double that amount. Although lumbar disk disease accounts for a small percentage of patients with back pain, it has been estimated that the annual medical cost for treatment of lumbar disk disease alone is nearly $5 billion.[1,2]

Heightened awareness of lumbar disk disease among family physicians will likely result in better care for patients with low back pain. However, the focused attention on this condition also increases the possibility that lumbar disk disease (or "suspected" lumbar disk disease) will be overdiagnosed, resulting in needless patient anxiety and unnecessary and costly interventions, including inappropriate surgery. Although patients with low back pain are commonly seen in family practice, only a small percentage present with a herniated intervertebral disk. More than 90 percent of all episodes of back pain can probably be attributed to mechanical causes, although the precise pathoanatomic lesion may not be identifiable.[1]

Extractions: This page contains a working JAVA applet that simplifies the use of the results of the Prospective Lumbar Discectomy Study. The Prospective Lumbar Discectomy Study was jointed sponsored by the American Association of Neurological Surgeons and the Congress of Neurological Surgeons, to try to identify factors that could be used to predict the outcome of lumbar disk surgery. In that study I performed a multivariate (stepwise logistic regression) analysis of eighteen factors, and found that six independently influenced to likelihood of a good outcome (at one year) from lumbar disk surgery. Since logistic regression results are odds ratios that are not easy to intuitively combine, I have created this calculator application to allow you to "plug in" various values for criitical patient factors to see their effect on the likelihood of a good outcome in the Prospective Lumbar Discectomy Study group of patients. NOT a substitute for medical consultation and is NOT a clinical tool. It just illustrates the results of the study in a more intuitive way.

Thirteen patients with foraminal or extraforaminal lumbar disk herniation were treated during a 32-month period. Myelography and magnetic resonance imaging proved to be ineffective in identifying the lesion in most patients. High-resolution computed tomography demonstrated the lesions in all patients, and the findings were subsequently confirmed at surgery. Surgical treatment consisting of disk fragment removal and nerve root decompression was effective in relieving radicular pain.

Extractions: Here at CMRS we often find ourselves going against conventional wisdom in our therapeutic recommendations. Our explanation for this is that we really care for patients and dig diligently for the right answers, and we are not bound by establishment blinders and the need for conformity to an established but arbitrary and often ineffective standard of orthodox care. One example of this difference is our long standing recommendation that acute injured limbs NOT be immobilized. I wrote an article in this e-newsletter some months ago that informed our readers that an establishment study had validated our view and had found that immobilization was counter-productive.
