Introduction: The position of column is important because when columns are placed further away from centre of load they can resist bending and buckling forces better than columns which are placed closer to each other.
Objective: This study has been attempted to find out the relative positions of the columns to each other by comparing mean arch indices and its ratio to mean inferior body surface area.
Materials and Methods: The 6 cervical and upper 5 thoracic vertebrae of 30 human adult male columns were selected for the study. The various parameters such as inferior body surface area, arch index and the ratio arch index to inferior body surface area were measured for each of the 6 cervical and upper 5 thoracic vertebrae of 30 columns.
Results: Measurements of the area of the inferior surface of the body, arch index and the ratio of arch index to inferior surface of the body. The ratio showed a gradual decline from C2 to T5 level. Above C7 level the size of the arch was greater than body area, but at T1 the two were of almost equal size, below which body area exceeded the arch size. In relation to the body area, neural arch size diminished considerably in the thoracic region.
Conclusion: The measurements obtained by the present study reveals the importance of neural arch in understanding the mechanics of spinal anatomy and its applications with respect to transmission of weight.
