Abstract

Introduction: Accurate anatomical descriptions of the size, shape and orientation of the main structures of the human vertebrae and intervertebral discs are necessary for a variety of approaches and objectives such as the identification of clinical situations that are related to the morphometry of the spine structures, such as the incidence of low-back pain related to the spinal canal size. So the present study was done to measure the various morphometric parameters of thoracic vertebral body and neural canal. Materials and Methods: Total 100 sets of dry human thoracic vertebra were obtained. These are of unknown age and sex. All Morphometric parameters were measured by digital Vernier caliper of accuracy of 0.01mm. Anterior height of the body (VBAH), Posterior height of the body (VBPH), Antero-posterior Diameter of Vertebral body (VBAPD), Transverse Diameter of Vertebral body (VBTD), Anteroposterior diameter of Vertebral Canal (VCAPD) and Transverse diameter of Vertebral Canal (VCTD). All parameters were entered into excel sheet and analysis was done by SPSS. Results: Mean VBAH ranged from 13.17+1.35mm (T1) to 17.92+2.25mm (T12), mean VBPH from 15.01+1.27mm (T1) to 20.92+4.58mm (T12), mean VBAPD ranged from 11.62+1.96mm (T1) to 18.12+5.71mm (T12), mean VBTD from 24.28+5.68mm (T1) to 28.59+5.97mm (T12), mean VCAPD ranged from 12.46+1.30mm (T1) to 16.05+2.41mm (T12) and VCTD from 17.15+2.19mm (T1) to 20.11+3.74mm (T12). Conclusion: The results of the present study may help in designing implants and instrumentations; understanding spine pathologies; and management of spinal disorder.
