Introduction: The typical thoracic vertebrae form essential part of the vertebral column which support the spine, aid respiration and anchor ribs. Their unique structure enables limited movement, essential for posture and stability.

Aim and Objective: This study measures various parameters of T2-T8 vertebrae for anatomical and clinical insights.

Materials and Methods: This study analysed 38 dry typical thoracic vertebrae of unknown gender and age from an anatomical collection, free of deformities. Morphometric measurements were taken using a digital vernier calliper.

Results: The typical thoracic vertebra exhibits a body with a superior ap diameter ranging from 14.65 to 25.01 mm (mean 19.13 ± 2.97 mm) and a posterior height of 14.72 to 22.10 mm (mean 17.48 ± 1.63 mm). The superior transverse diameter of 19.34 to 29.00 mm (mean 23.78 ± 2.41 mm) and an average height of right-side pedicles 9.75 ± 1.06 mm. The height of right-side laminae 17.63 ± 1.76 mm and width of right-side laminae are 5.88 ± 1.89 mm. The spinous process, projecting posteriorly has a length ranging from 27.32 to 47.83 mm (mean 35.89 ± 5.36 mm).

Conclusions: Detailed knowledge about this study will guide surgeons and orthopaedician in surgeries like vertebroplasty, fracture reduction surgeries and vertebral prosthetic surgeries.
