Abstract
New bone formation (e.g., periosteal reaction) is one component of bone and joint disease diagnosis. Its application in the archeologic record has been compromised by lack of standardization. An objective technique for validating observations seems especially valuable when visual examination of a single data set results in widely disparate perspectives. Such discrepancies as to presence or absence of periosteal reaction are amenable to objective analysis. Bone, as any other form of matter, has a variety of properties. Some are characterized by weight or volume and are referred to as colligative. Some are related to its intrinsic nature, independent of mass. The latter are referred to as non-colligative. Non-colligative properties of matter provide an opportunity to assess structure, independent of quantity. Study of one such property, entropy, revealed that taphonomic changes can confidently be distinguished from bone surface reaction. Contrasted with the homogeneous entropy of normal bone, the loss of surface bone inherent in taphonomy results in reduced entropy. Contrasted with the homogenous patterns of normal bone, specific non-homogenous patterns allow periosteal reaction to be recognized, independent of variety of periosteal reaction or its origin. Thermographic approach allows observational techniques to be independently validated. Such validation allows for greater facility in interobserver archeologic site sample comparisons.
