[Tomodensitometry of the humeral distal extremity. Morphologic and biometric study of the pillars]

Biometry by computerized tomography on osseous series has not yet been applied in physical anthropology. I performed computed tomographical cross-sections on nine distal human humeri, every three millimetres, up to five centimetres of their length. The bi-epicondylar width was the reference level to compare the bones. I took several measurements at each level for each bone, and each area was calculated. The results confirmed our previous data on dry bones. Many reproducible and valuable measurements were possible, the accuracy of several was increased, and new measurements were defined. The morphological analysis of density measurements added new data. The osseous areas were easily integrated. This method which does not alter bones is precise and important in osteological studies in modern and paleo-anthropological primatology.
