Measurement of normal end plates angle from T12 to L4 in Sudanese using Computerized Tomography.

Abstract

This study was done to identify the normal end plate angle from T12 to L4 for Sudanese patients using Cobb method as well as to assess the relation of these angles in both gender with age. The study was done in the period from November 2010 to July 2011. In Soba hospital, Yastabshiroon medical centers, Bugaa specialized hospital, Imperial hospital. 130 Sudanese patients (65 male and 65 female) with different ages; they had CT examination for abdomen, pelvic or lumbar spine. Lateral scout was done and all the cases were diagnosed as normal. Exclusion criteria were major trauma; any disease of the vertebral column, spinal canal, para-vertebral soft tissues. The measurement was done by drawing a perpendicular line to a line drawn from the superior end plate of the upper-end Of T12,L1,L2,L3,L4 vertebrae and the inferior end plate of the lower-end of T12,L1,L2,L3,L4 vertebrae; the angle formed by the intersection of the two perpendicular lines as Cobb angle which had been evaluated. . The study showed that for Male; the mean end plate angle was found to be 7.4±3.5for T12, 6.6±3.3 forL1,4.7±2.9 for L2, 5.3±3.8 for L3,18.8±7.6for L4. For -Female ; the mean end plate angle was 9.2±4.5for T12, 9.9±4.5 For L1, 9.8±4.3 for L2,6.8±4.3for L3, 5.9±4.6 for L4. The mean end plate of T12 was found to be increased significantly with age in male and female but no significant relation were found in L1,L2,L3,L4.
