Abstract:
Background: Pedicle screw fixation in the thoracic spine remains a technical challenge. Knowledge of the pedicle diameter and chord length is essential for choosing the appropriate pedicle screw, whereas the pedicle angle is important for accurate screw lacement.
Objective: To measure the various dimensions of pedicles in typical thoracic vertebrae. Material and methods: Two hundred dry human typical thoracic vertebrae of undetermined gender and age were selected for the study. The various parameters of pedicles were measured. Results: The mean pedicle width at the midpoint of the pedicle on the left was 4.33 ± 1.03 mm and on the right side was 4.29 ± 0.97 mm. The mean pedicle height at the midpoint of the pedicle on the left side was 10.54 ± 1.17 mm and on the right side was 10.6 ± 1.1 mm. The mean transverse pedicle angle on the left side was 14.37 ± 5.25 degrees and on the right side was 14.52 ± 5.3 degrees. The mean sagittal pedicle angle on the left side was 13.81 ± 3.27 degrees and on the right side was 13.82 ± 3.26 degrees. The mean chord length on the left was 35.94 ± 3.94 mm and on the right side was 35.83 ± 3.97 mm. Conclusion: Thus, a comprehensive data set has been presented which will help in development of pedicle instruments for Indian population.
