Introduction: Vertebral pedicle assessment is important in choosing appropriate pedicle screw for spinal fixation. Differences have been reported in morphology of vertebral pedicles in the literature between various ethnic groups. So, main objectives of this study is to record surgically relevant parameters using Computed Tomography Scan.

Methods: This prospective cross sectional study was performed from September 2016 to August 2017 on 110 patients (>18 years) referred for Computed Tomography scan to Department of Radiology, Tribhuvan University Teaching Hospital, Kathmandu, Nepal. Ethical approval was taken from Institutional Review Board, Institute of Medicine, Maharajgunj, Kathmandu, Nepal with reference number 368 (6-11-E)/074. The scans of lower thoracic and lumbar spine of patient, free from spinal disorders were reviewed for the morphology of vertebral pedicle. We analyzed 880 vertebrae. Parameters evaluated were chord length, depth along midline axis, transverse pedicle isthmus width and transverse pedicle angle. Data was collected in predesigned proforma in Microsoft Excel spread sheet and analysis were done using software, SPSS (Statistical Package for Social Science) version 16.

Results: Mean transverse pedicle isthmus width was least at T10 vertebral level (6.21 mm) while the largest was seen at L5 vertebral level (14.04 mm). The chord length was more than the depth along midline axis at all levels except at T11 and T12. The mean transverse pedicle angle faced laterally at T11 and T12 vertebral level.

Conclusion: It is sensible to ask for pre-operative Computed Tomography scans in order to choose appropriate screw size to prevent intra-operative and post-operative complications.
