To assess the age estimation from the degree of osteophyte formation of vertebral column, we set grading scores from 0 to 3 for the osteophyte formation based on the height of the process of vertebral column, and defined the average of the values at the cervical, thoracic and lumbar parts of the vertebra to be ‘osteophyte formation index’ for an individual. We evaluated osteophyte formation in autopsied 225 bodies (138 males, 87 females) during 5 years, and statistically analyzed the integrated data. The following were statistically obtained for each sex: correlation coefficient, regression equation, standard error of estimate (SE) between the score at each part of the vertebral column and age, and between ‘osteophyte formation index’ and age. In all the parts of the vertebra, there was a significant correlation between the score value and age. We recognized a significant correlation between ‘osteophyte formation index’ (X) and age (Y), and regression lines were Y=37.90+12.07X (SE; 12.6 y.o.) in males and Y=36.67+18.64X (SE; 11.9 y.o.) in females. It was apparent that to know the degree of the osteophyte formation was useful in age estimation.
