Fracture patterns among the Nubians of Semna South,Sudanese Nubia

A collection of 592 individuals from the site of Semna South in Sudanese Nubia was studied for evidence of healed fractures of the skull and appendicular skeleton. The sample included 241 males, 239 females, 109 subadults and three adults for whom a sex could not be determined. Potential analytical and interpretive bias due to vagaries of preservation was quantified and examined. Almost 21% of the adults exhibited at least one healed fracture, while only two subadults showed such trauma. Rates of fractures, calculated for each bone, varied from a high of 17.9% for the cranium to a low of 0% for the right femur. Some fractures were likely caused by the physical environment, for example, falls along the rocky shores of the Nile. Other trauma, such as craniofacial fractures, found in both males and females, may have been due to interpersonal violence. The high rate of craniofacial trauma may indicate that this group experienced social stress which could have precipitated or intensified interpersonal violence.
