In the antero-posterior views of the lumbar X-ray film of 294 normal Korean adults(124 males, 171 females), the following measurement was made: the measurement of the interpeduncular distance, width of the lumbar vertebral body and height, and thickness of the pedicle. The lumbar spinal canal was classified into 4 types and 7 subtypes, according to Piera et al. The mean value of interpeduncular distances of each lumbar vertebral level was measured in relation to the variables of sex and age.
The value of interpeduncular distances at each level was related to the pedicle index and width of the vertebral bodies. Statistical analysis was made.
The percentage ofy type A was 74.49%, type B, 20.75%, type C, 4.76%, but type D was not observed. The mean value of the interpeduncular distances of each level of the lumbar vertebra was measured. In male, L1 was 25.44㎜, L2, 23.80㎜, L3, 24.04㎜, L4, 25.36㎜, and L5, 28.41㎜, The difference between male and female was significant(p<0.05). The difference between each age group was not significant(F>3.58). There was no significant relationship between the interpeduncular distance, pedicle indices and the width of the body at all levels.
