Normal Lateral Recess Height Size on CT and MRI
Normal lateral recess height measures greater than 2 mm on CT and MRI; values at or below this threshold indicate stenosis requiring clinical correlation.

L
Normal Lumbosacral Angle Size on X-ray, CT & MRI
The normal lumbosacral angle measures 26–57° on lateral imaging; deviations correlate with low back pain, spondylolisthesis, and altered spinal biomechanics.
Normal Lumbosacral Disc Angle Size on X-ray, CT & MRI
The normal lumbosacral disc angle measures 10–15° on lateral imaging; deviations may indicate spondylolisthesis, disc pathology, or postural malalignment.
P
Normal Pseudosubluxation Size on Cervical Radiography
Normal pseudosubluxation at C2/C3 measures less than 3 mm on lateral cervical radiography, a critical threshold to distinguish physiologic from true subluxation.
Normal Pseudosubluxation Size on Cervical Spine Radiography
Normal cervical pseudosubluxation measures less than 3 mm at C3/C4 on lateral radiography, a key threshold for distinguishing physiologic from pathologic displacement.
S
Normal Spinal Canal Diameter Size on X-Ray, CT & MRI
Normal spinal canal diameter ranges 17–22 mm in the thoracic spine and 15–25 mm in the lumbosacral spine on radiography, CT, and MRI.
T
Normal Thoracic Wedge Compression Fracture Size on X-Ray/CT
Normal anterior-to-posterior vertebral height difference in thoracic wedge compression fracture is less than 3 mm on lateral radiography and CT.
V
Normal Van Akkerveeken Distance Size: X-ray, CT, MRI
Normal Van Akkerveeken distance is less than 3 mm on lateral radiography, CT, and MRI, serving as a key marker for lumbosacral instability.
W
Normal Wedge Compression Fracture Size on Radiography & CT
Normal anterior-posterior vertebral height difference for lumbosacral wedge compression fracture is <3 mm on lateral radiography and CT.
