“…It again showed increase from L4-L5. 26 It was also observed that the mean values for anteroposterior diameter of vertebral canal were found to be higher in males than females at L2 and L4 vertebral levels whereas these values were found to be higher among females at L1, L3 and L5 vertebral levels. Contrary to this study, Zhou et al and Alam et al, suggested that the antero-posterior diameter was higher among males than females at all levels of vertebrae.…”

Background: Lumbar region is the most vulnerable area for the common symptom of backache. The lumbar part of spinal canal encloses the cauda equina. Narrowing of the canal can be either developmental or acquired. This leads to compression of the cauda equina and subsequently pain develops which may be further associated with neurological features. The aim of the present study was to measure the dimensions of lumbar vertebrae. Methods: The present study was a descriptive and cross-sectional type. It consisted of 266 images of computed tomography scan of individuals. The various dimensions of lumbar vertebral canal and body were measured in millimeter. The descriptive statistical analysis was done. Results: The mean of the transverse diameter of lumbar vertebral canal increased from L1 to L5 but the antero-posterior diameter decreased from L1 to L4 followed by increased at L5. It was also observed that both transverse and antero-posterior diameter of body progressively increased from L1 to L5 vertebrae. The canal-body ratio was inconsistent for any vertebral level. There were significant differences in various dimensions of lumbar vertebrae between males and females. Conclusions: All the measured diameters of canal and body revealed increasing cranio-caudally sequence in the lumbar part of spine. The antero-posterior diameter of canal could attract the attention of clinician as an important structural change with significant radiological and clinical implications.

“…17,23,24 Al-Rakhawy et al and Banik et al encountered a dip in IPD at L3 level while Attar et al found the mean IPD increase to halt at L2 level. 23,25,26 Some studies have reported much larger values of IPD at L5 level. 5,24,25 The remarkably higher value at L5 was probably caused by the different configuration of the vertebra, in which the pedicles were more lateroventrally implanted on the body and were fused with the transverse processes.…”

“…23,25,26 Some studies have reported much larger values of IPD at L5 level. 5,24,25 The remarkably higher value at L5 was probably caused by the different configuration of the vertebra, in which the pedicles were more lateroventrally implanted on the body and were fused with the transverse processes. 27 Mansur et al noted that the transverse diameter of the spinal canal of any lumbar vertebra is proportional to the size of the vertebral body at that level and that its ratio with the body would be more helpful for identifyng spinal canal stenosis.…”

Background: Pedicle screw instrumentation has revolutionized spine surgery on account of its superiority over other stabilization systems. It is safe when properly placed and versatile for a range of procedure from fracture fixation to complex deformity correction. Sound anatomical knowledge of the pedicle may also be helpful during surgical approach to lumbar foramina disc herniation and epidural steroid injection as well as in the diagnosis of some lumbar degenerative diseases and chronic back pain. In this study we aimed to provide locoregional data on lumbar pedicle morphometry of Nepalese population. Methods: A descriptive observational study was conducted on 50 dry adult human lumbar vertebrae of unknown sex at Chitwan Medical College from August 2020 to December 2020. Pedicular width, height and the interpedicular distance were measured. All the data were numerally coded in excel and analysis was done in Statistical Package for Social Sciences (SPSS) version 20. Results: The mean width of the pedicles of left side gradually increased as we moved down the vertebrae and measured 7.43 ±0.84 mm in L1 and 12.18±1.71 mm in L5 vertebrae. The mean width of the pedicles on the right side, however, showed an increasing trend with a lower value at L3 level and was measured as 7.91± 1.17 mm. The mean height of the pedicles alternatively decreased and increased down the vertebrae for both the sides. The mean interpedicular distance gradually increased craniocaudally and was found to be 20.35±0.95 for L1 and 25.97±3.58 mm for L5 vertebrae. Conclusions: This study confirmed the measurement of lumbar pedicles’ dimensions and provides its regional data on Nepalese population. These data may be critical for clinicians working near the vicinity of the lumbar pedicles.

Background: The objective of this anatomical study was to perform the morphometry of dried lumbar vertebrae in human cadavers. Methods: This study utilized 200 adult human cadaveric dried lumbar vertebrae. The digital Vernier calipers was used to perform the measurements.The height, antero-posterior length, transverse length of the body of the vertebrae, interpedicular distance at the lateral ends, lamina length, height and thickness, superior and inferior articular facet height and width, mid sagittal and transverse diameter of vertebral foramen, height, width and thickness of the pars inter-articularis were measured. Results: The vertebral body’s anteroposterior length was more at the lower border than at the superior border (p < 0.01). The length of lamina was higher over the right in comparison to the left (p < 0.001). The height of lamina, width of inferior articular facet, diameter of lateral recess and thickness of pars inter-articularis were greater for the left sided specimens (p < 0.01). The statistical significance was not observed for the comparison of the remaining parameters (p > 0.05). Conclusion: This anatomical study offered several dimensions of lumbar vertebrae, which are essential in the surgical practice. The implants at the lumbar vertebrae need to be manufactured based on the anatomical dimensions of that particular sample population.
