RESUMO
OBJECTIVE: This study was undertaken to identify pathological conditions within the population living at Atalla (1000-500 BCE), an important early village site and ritual center located in Huancavelica, Peru. MATERIALS: Articulated burials (N = 3) and commingled human remains excavated during the 2015 and 2016 field seasons. METHODS: Osteological remains were analyzed for macroscopic evidence of pathological changes. RESULTS: A case of bilateral proximal radioulnar fusion was observed in an Early Horizon (ca. 800 BCE) subadult skeleton (Individual 1). A differential diagnosis of this pathology supports congenital radioulnar synostosis (CRUS), a rare developmental condition. Enamel hypoplasia was also identified in the same individual. CONCLUSIONS: Burial treatment of Individual 1 does not provide any indication that CRUS was afforded an exceptional social significance. CONTRIBUTION TO PALEOPATHOLOGY: This example of CRUS is notable as it represents the second published archaeological case of CRUS from Peru and the earliest reported case globally. LIMITATIONS OF THIS STUDY: The osteological sample currently available from this site is limited. SUGGESTIONS FOR FUTURE RESEARCH: Increased fieldwork in this region is recommended to further clarify the distribution and social significance of CRUS in the prehistoric Andes.
