Rare morphological variants of the bones: Epicondylar processes, metopic suture and Wormian bones in XVIII century skeleton

Abstract

Background: Analysis of the female skeleton from the 18th century revealed a collection of morphological changes. Materials and methods: Anthropological evaluation and dental X-ray techniques allowed the age to be determined at 12–13 years. Results: The distal parts of the both humerus bones had distinct, supracondylar processes of about 5 mm at the medial-lateral surface. The frontal bone had a well-preserved metopic suture along the entire length of the squama. There were also two Wormian bones (Inca bones), asymmetrical mastoid foramen, and only left non-obliterated condylar canal. Conclusions: The skull measurements allowed the cranial index to be determined — 93.5 (brachycephalia) and height-length index — 98.6 (akrocephalus). Moreover, X-ray analysis of incomplete dentition was made.
