1975;6:17796. Dural ectasia describes widening of the dural sac or spinal nerve root sleeves, usually associated with bony erosions of the posterior vertebral body 4. Diagnosis is based on clinical findings and is confirmed by cytogenetic analysis. Your physician will notify you of this prior to the Radiographic indices for lumbar developmental spinal stenosis. o [ abdominal pain pediatric ] however, you will need to let your physician know if you have ever had Fortuna A, Ferrante L, Acqui M, Santoro A, Mastronardi L. Narrowing of thoraco-lumbar spinal canal in achondroplasia. The black line indicates how the line connecting the facet joints should be outlined to identify the posterior margin of the pedicle width. Lumbar spine: There are 5 lumbar-type vertebral bodies. This was a general statement of the calculated results using the largest index (S1) for SBW:PW. All subjects were of Chinese ethnicity and were recruited via written consent since December 2012. Dural ectasia refers to ballooning or widening of the dural sac which can result in posterior vertebral scalloping and is associated with herniation of nerve root sleeves. The axial image used for measurement was the cut with the thickest pedicle diameter and could also visualize the whole bony ring at the pedicle level. Developmentally, the pedicle is the main reason for a narrowed spinal canal. Susan Standring. Orthop Clin North Am. the technologist through a window. Spine (Phila Pa 1976).

When you age, spinal discs can become larger (bulge) and ligaments can thicken, resulting in a narrower spinal canal. Jones RA, Thomson JL. Clinical presentation Patients with dural ectasia may present with low back pain or radicular pain in the buttocks or legs. Any tilt in the view exposes a double endplate contour because there is no longer overlap between the two sides of the endplate (anterior/posterior for AP view; medial/lateral for lateral view). Samartzis D, Karppinen J, Chan D, Luk KD, Cheung KM. Hence, it is likely that the cutoff values provided by the SBW:PW radio is more predictive of DSS. Radiology. : Diabetics should eat a light breakfast or lunch three hours prior to Craniocervical junction abnormalities can cause or contribute to cervical spinal cord or brain stem compression; some abnormalities and their clinical consequences include the following: Fusion of the atlas (C1) and occipital bone: Spinal cord compression if the anteroposterior diameter of the foramen magnum behind the odontoid process is < 19 mm, Basilar invagination (upward bulging of the occipital condyles): Protrusion of the odontoid process through the foramen magnum, typically shortening the neck and causing compression that can affect the cerebellum, brain stem, lower cranial nerves, and spinal cord, Atlantoaxial subluxation Atlantoaxial Subluxation Atlantoaxial subluxation is misalignment of the 1st and 2nd cervical vertebrae, which may occur only with neck flexion. 1990;72:4038. Interestingly, none of the subjects in the control group has DSS on MRI measurements. (2011) ISBN: 9780702033957 -, 2. The disease read more of the cervical spine can cause atlantoaxial dislocation or subluxation, basilar invagination, or platybasia. ROC analysis suggested sagittal vertebral body width to pedicle width ratio (SBW:PW) as having the strongest sensitivity and specificity for diagnosing DSS. The PW was measured from the posterior border of the vertebral body to the line connecting the cranial and caudal facet joints. Spinal canal.

Hence, we can expect these ratios to be consistent even on flexion-extension dynamic radiographs. In addition, these ratios are based on static bony parameters which are unlikely to be subjected to change with posture or movement as compared to other dynamic measurements. However, due to the obvious cost-related concerns of MRI, this study is conducted to develop new phenotypes of DSS on radiographs using easily measurable radiographic parameters. The dura is pierced with a needle during a lumbar puncture (spinal tap).

Neural tissue is flexible and susceptible to compression. of the spine), blood vessel malformations, or other conditions, Explanation of imaging report terms needed. - Donald Corenman, MD, DC This finding may be less frequent in the thoracic spine because the spinal canal is more capacious, and the spinal cord is relatively smaller at this level compared to the cervical spine. Procedures may vary depending on your condition and X-rays Foraminal Stenosis: What Causes It and How It's Treated - WebMD This is supported by our study results which proves that SBW:PW is the most significant index that has strong sensitivity and specificity in identifying DSS especially for L3S1 which are clinically the more commonly affected levels by lumbar spinal stenosis. PubMed The canal itself is primarily formed by the vertebral foramen of adjacent vertebrae. The canal consists of a series of vertebral foramina (the holes at the center of the vertebra) linked with discoligamentous structures. Reduce and immobilize the compressed neural structures. 1957 Apr;39-A(2):341-76 Some people with spinal stenosis have no symptoms. X-rays are superior due to its availability and cost, but currently, there is no definition of DSS based on plain radiographs. Only radiographic parameters with near-perfect agreement were used for radiographic indices and underwent receiver operating characteristic (ROC) analysis to identify the cutoff values that diagnose subjects with DSS. Although keen observational skills are critical for accurate spinal MRI interpretation, that ability is dramatically offset if observations are not accurately described and characterized. Australas Radiol. given a liquid contrast preparation to swallow. Before Anyone you share the following link with will be able to read this content: Sorry, a shareable link is not currently available for this article. The degree of constriction required to cause symptoms is unclear, but with a developmentally narrowed spinal canal, patients are more susceptible to canal compression. sharing sensitive information, make sure youre on a federal Orthopade. you can eat, drink and take your prescribed medications prior to your The IPD is another consistent landmark since the well-defined pedicle is usually seen clearly on AP radiographs. Fang D, Cheung KM, Ruan D, Chan FL. A potential limitation of our upper level (L1L2) indices is the lack of patients with upper level stenosis symptoms. In terms of radiation exposure, only two standing radiographs are required for assessment, and these are usually required prior to any treatment to assess the loaded spine since MRIs are performed in supine. As the scanner begins to rotate around you, X-rays will pass Symptoms vary with the cause but typically include ataxia (impaired read more usually impair coordination. The exact location of our measurement parameter is of little concern because we only require a consistent parameter that can reflect a short pedicle.

Craniocervical junction abnormalities are congenital or acquired abnormalities of the occipital bone, foramen magnum, or first two cervical vertebrae that decrease the space for the lower brain stem and cervical cord. detailed than standard X-rays. In this study, patients with DSS are diagnosed by the AP bony spinal canal diameter phenotype on MRI, which is the parameter determined to be the most representative of DSS and can be obtainable from axial MRI images [2, 31]. Craniocervical junction abnormalities are congenital or acquired abnormalities of the occipital bone, foramen magnum, or first two cervical vertebrae that decrease the space for the lower brain stem and cervical cord.
