Abstract

Objectives of the present study were to determine the anatomical parameters of the S1 pedicle in South Indian population and to compare the data, with respect to male and female genders.The stud¬¬y included 50 dry sacra (25 male and 25 female), which were obtained from the anatomy laboratory of our institution. It is observed in the present study that the mean S1 pedicle length was 49.9± 3.6 mm for male and 46.3± 4.8 mm for the female. The cephalocaudal heights of S1 pedicle were 27.2±4.0 mms and 23.9±3.7 mms for the male and female respectively. The anteroposterior width of S1 pedicle was 7.5± 1.3 mms, 7.5± 1.7 mms in males and females respectively. The anteroposterior distances of S1, from the sacral promontory to the spinous process of S1 were 52.9± 5.2 mms and 50.4± 6.8 mms respectively for the male and female genders. The present study observed that the mean S1 pedicle length and the cephalocaudal height were higher (p<0.05) for the males than that of females. The data (male vs female) were not found statistically different (p>0.05), with respect to the anteroposterior width of the S1 pedicle and the anteroposterior distances of S1 from the sacral promontory to the spinous process of S1. We report that the present study has provided important morphometric data onto the pedicle of the first sacral vertebrae, from the anatomical samples of the South Indian population. The knowledge of pedicle diameters of S1 is crucial to the safe placement of screws in the posterior transpedicular screw fixation.
