ABSTRACT

Background: The thoracolumbar vertebral column comprising of 17 vertebrae (thoracic:12; lumbar:5) is designed to support the combined weight of the head, upper limb and torso in erect position and also the weight of the burdens born upon these parts of the body. These weights subject the vertebral column mainly to the vertical compression forces, the magnitude of which increases in craniocaudal direction i.e. from T1-L5, thus the size of vertebral bodies also increase craniocaudally.

Purpose of study: The present study has been conducted upon vertebral bodies of 510 vertebrae (thoracic: 360; lumbar: 150) with the aim to provide a baseline data for mathematical modeling and biomechanical studies of human spine. The anteroposterior and transverse diameters of the vertebral body along its upper and lower surfaces were measured with  vernier calipers.

Results: All the linear dimensions increased from T1-L5 with few exceptions. The anteroposterior diameter on lower surface decreased slightly at L5 which showed that comparatively less compressive force is exerted upon L5 as compared with L4 or L3. On comparing on both surfaces, it was more at lower surface by 1mm from T1-L1 and almost same from L2-L5. Similarly, transverse diameter of vertebral body along upper surface was less in the centre than the maximum transverse diameter by 4-5mm in thoracic region and 2-3mm in lumbar region. Further it was more as compared to anteroposterior diameter at all levels on both surfaces.

Conclusion: In humans, the thoracolumbar vertebral column supports the combined weight of the head, upper limb and torso in erect position which subject it to vertical compression forces. The magnitude of these forces increase from T1-L5, increasing the size of vertebral bodies in same pattern.

Key Words: Anteroposterior Diameter, Transverse Diameter, Vertebral Body, Weight Bearing.
