A CT-based radiographic analysis of parameters of congenital lumbar neuroforaminal stenosis.

ABSTRACT:

Background

Quantitative parameters for the diagnosis of congenital lumbar stenosis (CLS) have yet to be universally accepted. This study establishes parameters for congenital stenosis of lumbar neuroforaminal dimensions (LNFD) using computed tomography (CT), assessing the influences of patient sex, race, and ethnicity.

Methods

Measurements of LNFD were performed on CT scans from 1,000 patients aged 18-35 years without spinal pathology.

Results

Irrespective of vertebral level, mean anatomic LNFD measurements were as follows: 8.66±2.1 and 8.76±3.14 mm for left and right widths, 17.76±2.74 and 17.7±3.26 mm for left and right heights, and 133.12±34.72 and 133.4±33.86 mm² for left and right areas. Threshold values for neuroforaminal stenosis, regardless of verte
