Assessment of Superior and Inferior End plates In Normal lumbar Vertebrae from L1 to L5, Using Computed Tomography in Sudanese Population

The purpose of this study was to standardize the normal values as reference for Cobb angle of lumbar vertebral in normal Sudanese subjects using Computerized Tomography (CT). This study was done at Al-Zytouna specialized hospital and Royal Care hospital. This is a descriptive study, the samples of 200 patients in different ages and different genders and used Cobb method in measurement. The lateral scouts for lumbar spine were obtained. Traumatic cases, any disease of the vertebral column, spinal canal, para vertebral muscles diseases cases were excluded. Toshiba CT scanner was used. The exposure factors were KVp120, MA10-50. End plates angle from L1 to L5 was measured using Cobb method for both genders and the data were correlated to their ages, weight, height and body mass index (BMI). . The mean Cobb angles of lumbar vertebrae in males were found to be (4.770), (4.800), (4.640), (4.990), (7.160), and in females (5.4200), (5.340), (5.280) (5.660), (8.050) for L1, L2, L3, L4 and L5 respectively. There were significant differences in the Cobb angle of lumbar spine between both genders at p value 0.05. The mean BMI in males was (24.53 kg/m2), and in females was (25.79 kg/m2), where was a linear relationship between Cobb angle of the lumbar vertebral and BMI There is significant differences in Cobb angle of lumbar spine between the two genders at p value 0.05. The study concluded that the mean Cobb angle of lumbar vertebral differs significantly from males and females Sudanese.
