spinal cord signal abnormalities. Patients with CSM have an average minimal AP canal diameter of 11.8mm, 1) and values ≤ 10mm were likely to be associated with myelopathy 2). Patients with an AP diameter < 14mm may be at increased risk, 3) and CSM is rare in patients with a diameter > 16mm, even with significant spurs 4)

IMPRESSION: Congenital narrowing of the AP diameter of the pedicles at all levels. MR examination of the lumbar spine is otherwise normal. 2014-10-16 These measurements were taken at the level of maximum spinal cord compression (MCL) identified as maximum reduction of AP spinal canal diameter in comparison with other segments. In patients with multisegmental involvement and a similar degree of spinal canal stenosis, the level with the smallest spinal cord area was chosen. It was concluded that a sagittal diameter of the cervical spinal canal of less than 12 mm from C3 to C7, 16 mm in C1 or 13 mm in C2 should be suspected as indicating a narrow canal in patients “Flattened” canal with predominantly reduced spinal canal AP diameter and flattened spinal canal contents; Predominantly reduced interlaminar angle and consequent prominence of the anteromedial border of facets; Combined type, with global reduction of all canal parameters, including the AP and transverse diameters, and the interlaminar angle. Congenital Spinal Stenosis. No measurements are absolute; however, AP dimensions of the spinal canal less than 10 mm in the cervical region and 12 mm in the lumbar region (see Fig. 3.7) are considered to be stenotic.To some extent canal dimensions are more critical in the cervical spine, due to the presence of the cord, and in this region AP diameters of 10 to 13 mm are considered to represent The AP diameter of the normal lumbar spinal canal varies widely from 15 to 27 mm.

Measurements of the canal dimensions have been undertaken and an AP diameter of I1 .S mm and an interpedicular distance of less than 16 are consistent with stenosis (Ullrich et al. 1980).

AP indicates anteroposterior. These factors include the patient's age, symptom duration, preoperative cervical curvature, preoperative high signal intensity within the spinal cord and preoperative spinal cord angulation, transverse area of the spinal cord, and the anteroposterior (AP) diameter of the spinal canal, spinal cord, and vertebral body at the maximum compression site (2– 4, 6– 8, 12– 16, 18, 22, 23, 26, 29 The AP diameter of the normal lumbar spinal canal varies widely from 15 to 27 mm. Lumbar stenosis results from an AP spinal canal diameter of less than 12 mm in some patients; a diameter of 10 mm is definitely stenotic and may be a primary source of symptoms.

The mean AP diameter of the spinal canal is 12 mm; Cross sectional area Minimal cross sectional area is normally at the level of the facet joints; The narrowest cross sectional area is at the level of L3/L4; Men have narrower spinal canals at the L3 - L5 levels; Canal area of 180 mm 2 ± 50 mm 2 is normal in the lumbar spine

Using lateral dynamic radiographs of the cervical spine, the AP diameter from C3 to C6 in the neutral position and Penning's jaw diameter in extension (jaw diameter) from C2/3 to C5/6 were measured. The number of trapezoid-shaped vertebral bodies with a thickened posterior margin were also counted as such thickening might be one of the causes of spinal canal narrowing.

The anteroposterior (AP) diameter of the normal adult male cervical canal has a mean value of 17-18 mm at vertebral levels C3-5. The lower cervical canal measures 12-14 mm. Cervical stenosis is It refers to the narrowing of the spinal canal, nerve root canals, or intervertebral foramina of the cervical spine.

The mean AP spinal canal diameter was 7.7±0.7 mm at the cervical level, 6.2±0.8 mm at the thoracic level, and 8.4±0.7 mm at the lumbar level.

I recently had an MRI that shows congenitally narrowed spinal canal from level C3 - C6. C3-C4 have diffuse disc bulge with spurs and moderate to severe narowing of the spinal canal to 5mm in AP diameter. C4-C5 has disc desiccation with diffuse disc bulge and osteophyte with moderately narrowing of the spinal canal to 7mm in AP diameter.

Absolute stenosis is defined as the anterior-posterior (AP) diameter of the spinal canal <10 mm. Relative stenosis: 10-12 mm AP diameter. CT and MRI can visualize both the central and lateral canals. Electromyography (EMG) and nerve conduction velocity (NCV) are additional studies that may be useful in differentiating peripheral neuropathy from lumbar spinal stenosis .

Lumbar Spinal Canal . It also represents a FMSD drawn between the middle of the posterior vertebral wall (more precisely the posterior longitudinal ligament) and the cranial part of the spinous process which is more ventral than the caudal part; on this caudal part is inserted the yellow ligament spinal canal. With flexion and extension, each structure displayed unique characteristics.

1 Etiology Acquired cervical stenosis results from age-related degenerative disk and facet disease with associated uncinate process hypertrophy, ligamentum flavum thickening, and buckling of the posterior longitudinal ligament. These measurements were taken at the level of maximum spinal cord compression (MCL) identified as maximum reduction of AP spinal canal diameter in comparison with other segments. In patients with multisegmental involvement and a similar degree of spinal canal stenosis, the level with the smallest spinal cord area was chosen.
