Abstract:The aim of this study is to establish normal values as reference for vertebral end plate from T12 to L4 in normal Sudanese subjects using computerized tomography (CT).130 lateral scout CT scans done using GE Healthcare machine with KV120, MA10-50 for lumber vertebra were obtained from subjects (65 males and 65 females) their ages ranged from (15-74) years old .Endplates angle from T12 to L4 were measured using Cobb Method for both genders and the data were correlated to their ages. For males the endplates mean angles were found to be 7.4±3.5,6.6±3.3,4.7±2.9,5.3±3.8,18.8±7.6 and for females 9.2±4.5,9.9±4.5,9.7±4.2,6.8±4.3,5.9,4.6 for T12,L1,L2,L3and L4 respectively. The research also studied the difference according to gender; it showed significant difference at p value 0.05, the end plates angles were affected as the subjects ages increase. The study concluded that the mean Cobb angle end plate differs significantly from males and females Sudanese subjects and it has relation with age and the values differs from what was mentioned in the previous studies, the knowledge of the normal end plates angle allows better characterization and diagnosis for vertebra from T12 to L4.
