Abstract

This comprehensive anatomical study on bones and X-rays regarding pedicles of lumbar vertebrae was performed in two parts. In the first part of the present work direct gross measurements of 3 different diameters (v, d, and 1) of both the pedicles of LI to L5 vertebrae (200 male and 200 female) were recorded through sliding vernier caliper. In the second part plain anteroposterior radiographs of the lumbar spine from 500 individuals (250 males and 250 females) were collected, and divided in 6 age groups and 2 different diameters (t and h) were recorded. The minimum horizontal diameter (d) of both the pedicles increased from LI to L5. Whereas, the vertical height (v) of both the pedicles increased from LI to L2, decreased from L2 to L3 and increased from L3 to L5. The anteroposterior length (1) increased bilaterally from LI to L2 and decreased from L2 to L5. All the aforementioned parameters were greater in male than corresponding vertebrae of female. Same trends were confirmed by the radiological study. The maximum horizontal diameter (t) of pedicles on both sides of vertebrae was significantly greater in females in less than 20 years of subjects, due to early pubertal growth spurt, whereas it was significantly greater in males in rest of all the age groups at all segments of vertebral spine. The maximum vertical height (h) of both the pedicles was significantly greater in males of age groups greater than 30 years from LI to L5.
