Lumbar vertebral canal morphometry for computerised tomography in spinal stenosis
Spine
|March 1, 1983
Summary
Computerised tomography aids in diagnosing spinal stenosis by identifying lesions. Morphometric data from human skeletons provides normal dimension ranges for accurate diagnosis.
Area of Science:
- Radiology and Imaging
- Orthopedic Surgery
- Anatomy
Background:
- Computerised tomography (CT) is a noninvasive imaging technique valuable for detecting space-occupying lesions in the lumbar spine.
- CT plays a growing role in confirming clinical diagnoses of spinal stenosis, including trefoil configuration and narrow lateral recess.
Purpose of the Study:
- To establish normal morphometric dimensions of the lumbar vertebral canal and nerve root tunnels.
- To provide reference ranges for diagnosing spinal stenosis using computerised tomography.
Main Methods:
- Morphometric analysis of a large sample of human skeletons.
- Data collected across both sexes, two racial groups, and all five lumbar vertebral levels.
Main Results:
- Established a comprehensive dataset of lumbar vertebral morphometry.
- Provided normative ranges for key spinal canal and nerve root tunnel dimensions.
Conclusions:
- Morphometric data is essential for the accurate diagnosis of spinal stenosis via computerised tomography.
- This study provides critical reference values to enhance diagnostic accuracy in spinal stenosis.
