Osteoarthritis in Hands, Feet, Spine, and Temporomandibular Joint from Individuals Buried at Tiwanaku Sites in Moquegua, Peru
Author(s): Sara Becker
This study evaluated evidence of osteoarthritis in the multiple joints of the wrist and hand (ulnae, radii, carpals, and metacarpals, finger phalanges), ankle and feet (tibia, tarsals, metatarsals, foot phalanges), spine (cervical, thoracic, lumbar vertebrae), and temporomandibular joint from human skeletal remains previously excavated from Tiwanaku sites within the Moquegua Valley of Peru (AD 500-1000). Osteoarthritis, a type of degenerative joint disease with a complex etiology, has been shown to occur in situations where movements are repeated frequently enough to damage joint surfaces. This skeletal condition was used to understand patterns and levels of activity from five Tiwanaku colony sites (M1, M10, M11, M43, M70). Data were collected from older juveniles and adults (n=183), cross-evaluated by age-at-death and sex, and preliminary results show differences, especially in hands, feet, and spine, between individuals from these sites. In addition, evidence of osteoarthritis in the temporomandibular joint, especially among younger folk, may be related to artificial cranial modification. Overall, these results support the idea that the site groupings represent spatial differences in occupation and that repetitive labor likely began among older subadults (10+ years) in the prehistoric Andean culture of Tiwanaku.
