Tibial surgery in ancient Peru

Abstract

This case study describes a unique anthropogenic modification of two individual skeletons excavated from the pre-Columbian site of Kuelap, Chachapoyas-Amazonas, in the northeastern highlands of Peru. While numerous examples of cranial trepanations using an adjacent drilling technique have been recovered from this site and region, this is the first example of such a surgical technique on a post-cranial element. Skeletal remains demonstrate that ancient Andeans were skilled and successful with many surgical treatments. Ethnohistoric documents suggest the Chachapoya shamans were known for their healing. In these cases, however, there is no evidence of long-term healing. This innovative medical procedure appears to have been an attempt at therapeutic intervention intended to treat an osteomyelitic infection of the distal tibial metaphysis.
