Measurement of Normal Lumbar Spinal Canal in Sudanese using Computed Tomography

Abstract

This was an analytical studyconducted to measure normal lumbar spinal canal in Sudanese population using computed tomography.CT KUB images were taken for 50 adult patientstheir age ranged from 20 to 50 yearsexamined at Alamal National Hospital. The measurement of lumbar canal was taken from L1 to L5 in axial cut from CT images. The results of the study showed that the mean value of midsagittal measurement in the axial cut at L1 was 15.36±1.777mm; L2 was 14.45±1.721mm,forL3 was13.68±1.765 mm,for L4 was 13.21±1.784mm and for L5 was 15.11±2.927mm. The meanvalues of transverse measurement in the axial cut were21.01±2.662mm, 22.36±2.775 mm, 24.36±3.641 mm, 26.48±4.175 mm, and 28.54±4.552 mm from L1 to L5 respectively. The variations in midsaggitaldiameter do not exhibit significant differences between genders as observed in other population groups, except for L1 and L5. The dimensions of transverse and mid sagittal diameter of lumbar spinal canal in male population were higher than female population.In this study the relationship between the patient height and weight measurement in the axial cut was found to be indirect relationship.
