“Morphometric Study of intervertebral disc at Lumbar region- MRI Study”

Abstract

Introduction- From C2 to the sacrum, the intervertebral discs serve as the main connecting elements between the neighboring surfaces of the vertebral bodies. Except for the locations of the uncovertebral (neurocentral) joints of Luschka, the disc outlines match those of the nearby bodies. Both inside individual discs and in different locations, their thickness varies.

Material and methods- A retrospective evaluation of the morphometric parameters of the lumbar intervertebral disc was conducted on 150 patients with lower back pain aged 25 to 75 years in the Department of Anatomy, D Y Patil Medical College, in collaboration with the Radiology Department of D Y Patil Hospital, Nerul, Navi Mumbai.

Result- In the present study, we observed that the average anteroposterior diameter of lumbar intervertebral disc was 27.516±4.927, 28.484±5.179, 29.09±4.837, 30.553±5.13, and 29.037±4.74 mm at L1-L2, L2-L3, L3-L4, L4-L5, and L5-S1 of lumbar intervertebral disc, respectively. The average transverse diameter of lumbar intervertebral disc was 32.673±5.274, 34.884±6.456, 38.513±6.405, 40.908±6.30, and 40.476±7.55 mm at L1-L2, L2-L3, L3-L4, L4-L5, and L5-S1 of lumbar intervertebral disc, respectively. The average vertical diameter of lumbar intervertebral disc was 7.735±2.18, 8.18±2.26, 9.47±2.4, 10.96±2.623, and 10.98±3.94 mm at L1-L2, L2-L3, L3-L4, L4-L5, and L5-S1 of lumbar intervertebral disc, respectively.

Conclusion: This study revealed a significant correlation between males and females of the lumbar intervertebral disc. It is anticipated that these data would support operating neurosurgeons and spine surgeons in procedures like decompression and laminectomy.
