Anatomic morphological study of thoracolumbar foramen in normal adults

Abstract

Background: Based on CT images of the thoracolumbar intervertebral foramen and its surrounding parameters, and analyzing the intervertebral foramen morphology and the correlation between the measured parameters, to provide an anatomical basis for clinical minimally invasive transvertebral surgery. Materials and methods: Ten fresh adult cadaveric specimens (32-50 years old) with bilateral (T1-S1) spinal segments were selected for a total of 20 sides, a total of 340 intervertebral foramen, were measured with vernier calipers in the Department of Anatomy, Inner Mongolia Medical University. The intervertebral foramen height, the minimum sagittal diameter of the foramen, the width of the spinal ganglion, the sagittal diameter of the spinal ganglion and the sagittal diameter of the intervertebral foramen were measured. This study was reviewed and approved by the local Ethics Committee. Results: The results of the minimum sagittal diameter of the T9-10~L5/S1 intervertebral foramen were 6.
