RADIOLOGICAL EVALUATION OF INTERVERTEBRAL FORAMINA OF LUMBAR REGION IN SYMPTOMATIC AND ASYMPTOMATIC SUBJECTS
Journal Title: JOURNAL OF ANATOMICAL SCIENCES - Year 2017, Vol 25, Issue 2
Abstract
Introduction: Spinal stenosis is defined as the narrowing of central spinal canal or its lateral recesses. Stenosis of spinal canal becomes important only when it results in interference with the normal functions of the contents of the canal. The present study was aimed to evaluate the clinical relevance of stenosis of intervertebral foramina through the most recent technique MRI. Material & Methods: Antero-posterior diameter (APD) of intervertebral foramina of both sides was taken into account to ascertain any deviation from normal. The data was statistically analyzed using unpaired “t” test with Welch correction. Antero-posterior diameter of intervertebral foramina were compared between symptomatic and asymptomatic subjects and statistically analyzed. The data was represented as mean ± SEM (Standard Error of Mean). A probability (p) value of less or equal to (≤) 0.05 was considered statistically significant and all diameters were taken in millimeter. Results: The diameter of intervertebral foramina of left and right side was maximum at L1L2 level and minimum at L4L5 level in both symptomatic and asymptomatic subjects. The diameter of left neural foramina was slightly more than that of right ones. Minimum diameter was seen at L4L5 level making this level susceptible to compressive symptomatology.
