The calcaneus secundarius is an accessory ossicle of the anterior calcaneal facet. Dry bone examination of 1,367 calcanei revealed this trait 47 times (3.4%). Familiarity with the calcaneus secondarius may prove to be of clinical and radiographic value in distinguishing pathologic from normal variants in the calcaneus.
An unusual foot deformity in an archaeological specimen from Oldham County, Texas, is presented. It is hoped that through description and radiographic and photographic examination the readers will be able to offer opinions concerning the frequency or possible etiology of the condition.
The authors present a pictorial essay showing the range of variability of separate and attached os trigona in dry-bone specimens. The presence of free os trigona is found to be 1.7% in an early 20th-century skeletal sample, with no findings of the trait in 513 tali of prehistoric native Americans and Eskimos.
A unilateral foot deformity in an archaeological specimen from Point Hope, Alaska, is presented. Radiographic and gross examination of the bones of the malformed left foot suggests that this adult female suffered from a rare and possibly unique limb deficiency presenting as unilateral congenital absence of the phalanges, synostosis and hypoplasia of the metatarsals, and mild hypoplasia of the calcaneus.
The authors have presented a forensic anthropology case that established positive identification by comparison of antemortem and postmortem x-rays of the legs and feet. This case illustrates one method of ascertaining the identity of a burned and skeletonized victim. By careful reconstruction and examination of the skeleton, the investigators were able to determine not only age, race, and sex, but also trauma sustained to the head and left arm at the time of death. This case highlights the importance and application of clinical radiography in a legal context.
