“…2 The variability in width, height, orientation and interpedicular distance makes pedicle screw insertion very challenging. 3 For a successful surgery and appropriate implant design, sufficient knowledge of lumbar vertebral pedicle morphometry and anatomical data is critical in order to avoid inadvertent penetration of the pedicle wall. 4 The anatomy of the lumbar pedicle has been extensively studied previously using cadavers, dry bones and different imaging techniques; however, wide regional variations has been noted.…”

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.

“…The authors mentioned that, load has to pass through the pedicles against gravity at L5 level 7,19,28 . Therefore, the transfer of load from the body to the laminae in L5 will be upwards against gravity, making L5 possess the strongest pedicles with maximum thickness 3 . In the present study also the thickness of pedicles is maximum at L5 level on both sides and in both genders.…”

“…The lumbar pedicles play an important role in the transfer of body weight from the neural arch to the anterior part of the vertebral column 2 . An accurate knowledge of the lumbar pedicle dimensions has imperative implications for surgical interventions 3 . The majority of clinicians apply anatomical landmarks to guide pedicle screw placement in the lumbar spine 4 .…”

Background: The vertebral column is the central pillar of the body which has cervical, thoracic, lumbar, sacral and coccygeal parts. Out of these, the lumbar part is made up of five lumbar vertebrae which lies between the thoracic part above and the sacral part below. Objective: The study aimed to measure pedicle dimensions of lumbar vertebrae by using computed tomography scan. Methodology: This is a descriptive cross-sectional study which was conducted on 115 images of computed tomography scan collected from the Department of Radio-Diagnosis, Dhulikhel Hospital between May and October 2019 after receiving ethical approval from the Institutional Review Committee. All the scans available in the department were taken for the study. Point estimate at 95% Confidence Interval was calculated along with frequency and proportion for binary data. Data analysis was done in the Statistical Package for the Social Sciences version 16 (SPSS 16.0). Results: The pedicle chord length and breadth progressively decrease from L1 to L5 vertebral levels and pedicle thickness gradually increases from L1 to L5 vertebrae on both sides in both genders. The pedicle chord lengths were found significantly different whereas breadth and thickness were insignificantly different between males and females at all lumbar vertebral levels except at L1 for breadth. Conclusions: The pedicle chord length and breadth gradually decreases whereas thickness increases from L1 to L5 vertebral levels amongst Nepalese population.

“…Thus detailed knowledge about the pedicle size and dimensions is required while using the pedicle. 7 Fracture of the pedicle may occur due to the use of relatively oversized screw. Thus minimum diameter of the pedicle is required for the choice of the screw.Thus accurate anatomical knowledge of the morphometry of vertebral pedicle are also important for preoperative procedure planning and in the design and manufacture of pedicle screws.…”

Background: In the dynamic part of the spinal column the lumbar vertebra are the largest vertebra that support the maximum body weight and exhibit the greatest degree of degenerative changes. Pedicles of the vertebra act as a port to perform procedures inside the bodies of the vertebra such as biopsies, vertebroplasties or kyphoplasties. Pedicle screw fixation is a technically demanding procedure. Accurate anatomical knowledge of the morphometry of vertebral pedicle are also important for preoperative procedure, planning and in the design and manufacture of pedicle screws. The objective of this study to observe the morphometry of lumbar pedicles to determine the size of the screw in transpedicular screw fixation on the perspective of Bangladesh. Materials and methods: A descriptive observational study was conducted at Southern Medical College and Hospital in the Department of Anatomy on 65 dry adult human lumbar vertebra from December 2020 to May 2021. Width height of pedicle along with antero-posterior diameter of lateral recess (Depth) were observed by using digital Vernier Calipers and after recording data were analysed. Results: The study shows that there is gradual increase in the mean width of the pedicles on both right and left side from L1 to L5. Mean height of the pedicle and antero-posterior diameter of lateral recess both showed decrease at the level of L3 both on the right and left side. Conclusions: The measured data will give a gross measurement of pedicle of lumbar vertebra on Bangladeshi people, hope to provide the clinicians a better support during working with pedicles.
