Ninety percent of acute attacks of sciatica will resolve with conservative management within 4 to 6 weeks; only 5 remain disabled longer than 3 months (Gibson and Waddell, 2007; Lehrich and Sheon, 2007; ahcpr 1994). Conservative management for lbp includes: avoidance of activities that aggravate pain Chiropractic manipulation in the first 4 weeks if there is no radiculopathy cognitive support and reassurance that recovery is expected Education regarding spine biomechanics Exercise program heat/cold modalities for home use limited bed rest with gradual. For acute low back pain, the only therapy with good evidence of efficacy is superficial heat." According to a draft technology assessment prepared for the Agency for healthcare research and quality (ahrq) by the duke evidence-based Practice center on spinal fusion for treatment of degenerative. These include medical management (such as nsaids, etc. pain management, injections, physical therapy, exercise and various forms of cognitive rehabilitation. . Such conservative treatments are seldom applied in a comprehensive, well-organized rehabilitation program, although some such programs do exist. .

Spondylolisthesis refers to the forward slippage of one vertebral body with respect to the one beneath. . This most commonly occurs at the lumbosacral junction with L5 slipping over S1, but it can occur at higher levels as well. . It is classified based on etiology into 5 types: dysplastic, defect in pars interarticularis, degenerative, traumatic, and pathologic. . The most common grading system for spondylolisthesis is the meyerding grading system for severity of slippage, which categorizes severity based upon measurements on lateral X-ray of the distance from the posterior edge of the superior vertebral body to the posterior edge of the adjacent inferior. The distance is then reported as a percentage of the total superior vertebral body length (see appendix). Guidelines for the approach to the initial evaluation of lbp have been issued by the Agency for healthcare research and quality (1994) and similar conclusions were reached in systematic reviews (Jarvik et al, 2002; Chou et al, 2007; nice, 2009). . For adults less than 50 years of age with no signs or brains symptoms of systemic disease, symptomatic therapy without imaging is appropriate. For patients 50 years of age and older or those whose findings suggest systemic disease, plain radiography and simple laboratory tests can almost completely rule out underlying systemic diseases. . Advanced imaging should be reserved for patients who are considering surgery or those in whom systemic disease bank is strongly suspected. . Conservative care without immediate imaging is also considered appropriate for patients with radiculopathy, as long as symptoms are not bilateral or associated with urinary retention. . Magnetic resonance imaging (MRI) should be performed if the latter symptoms are present or if patients do not improve with conservative therapy for 4 to 6 weeks. .

For use of evoked potentials in spinal surgery, see cpb 0181 - evoked Potential Studies. Background The lifetime incidence of low back pain (LBP) in the general population is reported to be 60 to 90 with annual incidence. . According to the national Center for health Statistics (Patel, 2007 each year,.3 of new patient visits to primary care physicians are spondylolisthesis for lbp, and nearly 13 million physician visits are related to complaints of chronic lbp. . The causes of lbp are numerous. . For individuals with acute lbp, the precise etiology can be identified in only about 15 of cases (Lehrich et al, 2007). The initial evaluation of patients with lbp involves ruling out potentially serious conditions such as infection, malignancy, spinal fracture, or a rapidly progressing neurologic deficit suggestive of the cauda equina syndrome, bowel or bladder dysfunction, or weakness, which suggest the need for early diagnostic testing. . Patients without these conditions are initially managed with conservative therapy. The most common pathological causes of lbp are attributed to herniated lumbar discs (lumbar disc prolapse, slipped disc lumbar stenosis and lumbar spondylolisthesis (Lehrich and Sheon, 2007).
Similarly, foraminal stenosis is graded as: grade 0 refers to the absence of foraminal stenosis; mild foraminal stenosis (with some perineural fat obliteratio)n; moderate foraminal stenosis (showing perineural fat obliteration engelsk but no morphological changes and severe foraminal stenosis (showing nerve root collapse or morphological change). certain fusion procedures are considered experimental and investigational: for interlaminiar lumbar instrumented fusion (ilif coflex-f implant for lumbar fusion, and minimally invasive transforaminal lumbar interbody fusion (mitlif see cpb 16 - back pain: Invasive procedures. Also see cpb 772 - axial Lumbar Interbody fusion (Axialif). Notes: For purposes of this policy, Aetna will consider the official written report engelsk of complex imaging studies (e.g., ct, mri, myelogram). . If the operating surgeon disagrees with the official written report, the surgeon should document that. The surgeon should discuss the disagreement with the provider who did the official interpretation, and there should also be a written addendum to the official report indicating agreement or disagreement with the operating surgeon. For use of mesenchymal stem cell therapy for spinal fusion, see cpb 0411 - bone and Tendon Graft Substitutes and Adjuncts. .

Degenerative changes of the cervical spine have been observed in as many as 95 of asymptomatic individuals older than 65 years. Myelopathy is believed to develop in up to 20 of individuals with evidence of spondylosis. 5, 11, 13, 14, 15, 16, 17 lateral cervical stenosis results from encroachment on the lateral recess and the neuroforamina of the cervical region, primarily as a result of hypertrophy of the uncovertebral joints, lateral disc annulus bulging, and facet hypertrophy. Thoracic spinal stenosis The thoracic spinal canal varies from 12 to 14 mm in diameter in the adult. Thoracic spinal stenosis is often associated with focal disease of a long-standing nature. It may be associated with disk bulging or herniation, hypertrophy of the posterior elements (namely, the facet and ligamentum flavum and, occasionally, calcification of ligamentum flavum.
Primary central thoracic spinal stenosis is rare. In some cases, hypertrophy or ossification of the posterior longitudinal ligament results in central canal stenosis. 6 lateral thoracic stenosis may result from hypertrophy of facet joints with occasional synovial cyst encroachment. Lumbar spinal stenosis The diameter of the normal lumbar spinal canal varies from 15 to. Lumbar stenosis results from a spinal canal diameter of less than 12 mm in some patients; a diameter of 10 mm is definitely stenotic. Keim and colleagues present the following lumbar spinal stenosis (LSS) anatomical classification scheme 18 : Lateral, secondary to superior articulating process (SAP) hypertrophy medial, secondary to inferior articulating process (IAP) hypertrophy central, due to hypertrophic spurring, bony projection, or ligamentum flavum/laminar thickening Fleur de lis.
Degenerative spondylolisthesis of the lumbar Spine - spineUniverse
In hyperflexion, neural structures are tethered anteriorly against the bulging disc annulus and spondylitic bars. In the event of a vertebral collapse, the cervical spine loses its shape, which may result in anterior cord compression. In the central cervical spinal region, hypertrophy of the ligamentum flavum, bony spondylitic hypertrophy, and bulging of the disc annulus contribute to development of central spinal stenosis. In each case, the relative significance of each structure contributing to the stenotic pattern is variable. Congenital stenosis of the cervical spine may predispose an individual to myelopathy as a result of minor trauma or spondylosis. 5, 6, 10, 11, 12, 13, 14, cervical spondylosis refers to age-related degenerative changes of the cervical spine. These changes, which include intervertebral disk degeneration, disk space narrowing, spur formation, and facet and ligamentum flavum hypertrophy, can lead to the narrowing of the cervical spinal canal. Cervical spondylotic myelopathy (CSM) refers to the clinical presentation resulting from these degenerative processes. Csm is the most common cause of spinal cord dysfunction in adults older than 55 years.
The lower cervical canal measures 12-14. Cervical stenosis is associated with an ap diameter of less than 10 mm, while diameters of 10-13 mm are relatively stenotic in the upper cervical region. Sagittal measurements taken of the anteroposterior diameter of the cervical spinal canal are highly variable in otherwise healthy persons. An adult male without spinal stenosis has a diameter of 16-17 mm in the upper and middle cervical levels. Magnetic resonance imaging (MRI) scans and reformatted computed tomography (CT) images are equally as effective in obtaining these measurements, while radiography is not accurate. View Media gallery, movement of the cervical spine exacerbates congenital or acquired spinal stenosis. In hyperextension, the cervical cord increases in diameter. Within the canal, the anterior roots are pinched between the annulus margins and spondylitic bony bars. In the posterior canal, hypertrophic facet joints and thickened infolded writing ligamentum flavum compress the dorsal nerve roots.
nerve root is impinged by L5 sap). The mid zone extends from the medial to the lateral pedicle edge. Mid-zone stenosis arises from osteophytosis under the pars interarticularis and bursal or fibrocartilaginous hypertrophy at a spondylolytic defect. Exit-zone stenosis involves an area surrounding the foramen and arises from facet joint hypertrophy and subluxation, as well as superior disk margin osteophytosis. Such stenosis may impinge the exiting spinal nerve. Far-out (extracanalicular) stenosis entails compression lateral to the exit zone. Such compression occurs with far lateral vertebral body endplate osteophytosis and when the sacral ala and L5 transverse process impinge on the L5 spinal nerve. Cervical stenosis, the anteroposterior (AP) diameter of the normal adult male cervical canal has a mean value of 17-18 mm at vertebral levels C3-5.
Lumbar computed tomography (CT) myelogram scan demonstrates a normal central canal diameter. Lateral recess summary stenosis (ie, lateral gutter stenosis, subarticular stenosis, subpedicular stenosis, foraminal canal stenosis, intervertebral foramen stenosis) is defined as narrowing (less than 3-4 mm) between the facet superior articulating process (SAP) and the posterior vertebral margin. Such narrowing may impinge the nerve root and subsequently elicit radicular pain. This lateral region is compartmentalized into entrance zone, mid zone, exit zone, and far-out stenosis. Amundsen and colleagues found concomitant lateral recess stenosis in all cases of central canal stenosis. 9 (see the image below. lateral and axial magnetic resonance imaging (MRI) scan demonstrating right L4 lateral recess stenosis secondary to combination of far lateral disk protrusion and zygapophysial joint hypertrophy. View Media gallery, the entrance zone lies medial to the pedicle and sap and, consequently, arises from facet joint sap hypertrophy.
Spondylolisthesis overview Grades, causes, and Treatments
Central canal stenosis, commonly occurring at an intervertebral disk level, defines midline sagittal spinal canal diameter narrowing that may elicit neurogenic claudication (NC) or pain in the buttock, thigh, or leg. Such stenosis results from ligamentum flavum hypertrophy, inferior articulating process (iap facet hypertrophy of the cephalad vertebra, vertebral body osteophytosis, vertebral body compression fractures, and herniated nucleus pulposus (HNP). Abnormalities of the disk usually do not cause qualitative symptoms of central stenosis in a normal-sized canal. In developmentally small canals, however, a prominent bulge or small herniation can cause symptomatic central stenosis. Large disk herniations can compress the dural sac and compromise its nerves, particularly at the more cephalad lumbar levels where the dural sac contains more nerves. (see the images below.).
