A morphomertic study of dry human typical thoracic vertebral body in coastal region, Andhra Pradesh

Background: The frequent surgical interventions of the thoracic spine are more common due to a wide array of traumatic, degenerative, and neoplastic diseases. For successful surgical management of these conditions, detailed anatomical knowledge of the thoracic vertebrae is required. Previous studies in the past about morphometry of thoracic vertebrae mainly focused on pedicle diameters and their angulations. The vertebral body was not studied particularly in the coastal region, Andhra Pradesh which is the reason the present study has given importance to the morphometry of the vertebral body. Aim was to measure the various parameters of the vertebral body in typical thoracic vertebrae.Methods: 82 dry human typical thoracic vertebrae from the department of anatomy, Andhra Medical College, Visakhapatnam were studied for the various morphometric parameters.Results: The antero posterior distance of the vertebral body in typical thoracic vertebrae ranged from 14.5-27.5 mm with a mean of 21.77 mm. The vertebral body superior transverse diameter ranged from 18.1-38.7 mm with a mean of 28.22 mm. The vertebral body inferior transverse diameter ranged from 22.6-41.2 mm with a mean of 31.3 mm. The anterior height of the body ranged from 10.2-24.1 mm with a mean of 18.17 mm. The right and left lateral height of the body ranged from 9.0-24.7 mm with a mean of 18.4 mm.Conclusions: The results provide information for more accurate modelling and design of vertebral body implants and instrumentations for the Indian population.
