Standardization of long bone growth in children

Abstract Diaphyseal lengths of long bones of juveniles from five prehistoric Native American populations were collected in order to test the hypothesis of equivalence of relative lengths of all long bones. Results indicate that the relative lengths of all long bones are not equivalent and that the long bones of the Native Americans exhibit a consistent, significant sequence from relatively most affected (relatively smallest) to relatively least affected (relatively longest): femur, fibula, tibia, humerus, ulna and radius. This sequence can be explained if it is assumed that the most rapidly growing long bones are the most greatly affected by nutritional and disease stress.
