Abstract: Introduction: Measurement of bone or any part of human body provides accurate knowledge about morphology of the structure which helps the clinicians in diagnosing and treating various diseases. Due to present lifestyle and with its speed, it has resulted in increase in the incidence of assaults on the vertebral column in the form of different spinal pathologies such as prolapsed intervertebral discs, spondylolisthesis, spondylosis, fractures
[1]. The horizontal diameter of pedicle decides the screw diameter. The transverse (width) and vertical (height) parameters of pedicle help in determining the screw path. So, the pedicle morphometry becomes important in the selection of most suited pedicle screw. The morphometry of the pedicle may vary from population to population.
Aims and objectives: To investigate the variability of the morphology and provide morphometric data of crucial parameters useful for accurate designing and placement of lumber pedicle screw. The result of this study can be used to carry out larger studies.
Method and Materials: This prospective study is based on Salim A. Lad et al. [2]. Data was collected by CT scan measurement of the pedicles along with its parameters (vertical height and width), and was compared with other associated studies with a collection of a mixed group of 80 patients age group of 18–60 years admitted to R.N.T Medical College and M. B. Hospital, Udaipur.
Result: The mean L1 pedicle width from left is 7.20mm and from right side is 7.23, L2 pedicle width from left is 7.88 and from right side is 7.90, L3 pedicle width from left is 9.20 and from right side is 9.23, L4 pedicle width from left is 10.5 and from right side is 10.51 and L5 pedicle width from left is 12.7 and from right side is 12.7mm.
Conclusion: In the present study we have made an attempt to understand the morphometry of the lumbar pedicles to decrease the risk of postoperative complications. The present study concludes that the different dimensions of the pedicle which have been studied would be of great help for successful pedicle screw fixation and also for quantification of spinal stenosis. There are, of course, a few limitations in our study.
