Estimating adult stature from radiographically determined metatarsal length in a Spanish population.

The ability to determine height in adult life can be crucial in the identification of skeletal remains. Very often, the small bones found among such remains are not only the most numerous, but also the best preserved, a fact which calls for more research into developing methods to estimate height from metatarsals. The aim of this paper is to verify the use of the dimensions of the metatarsals as estimators of adult height in a Spanish population using radiologically determined metatarsal lengths and to propose regression equations and test the formulae for determining adult stature. The present research is based on a study of 228 healthy Caucasoid adults from Galicia (NW Spain). The first and second metatarsals of the left foot were measured by a dorso-plantar X-ray using a digital medical image viewer. The best correlation obtained was with the maximum length of the 1st metatarsal for males. The corresponding regression equation is as follows: S=819.88+12.79 M1. A comparison of our statistical results with those of neighbouring population groups indicates that ours is more accurate. This must be due to the so-called specificity of regression equations in relation to the series on the base from which they were developed.
