Abstract
Olduvai Hominin (OH) 8, a 1.76 million year old left foot skeleton, has osteophytic lipping on the metatarsal bases, which when compared to a modern sample, may help paleoanthropologists determine whether the foot bones represent an injured subadult or an osteoarthritic adult. This study compares the OH 8 lipping pattern to those of 140 individual Amerindians comprising four different age classes to determine whether the OH 8 lipping is likely to be age-related osteoarthritis. OH 8 metatarsal lipping followed a pattern similar to that determined in the comparative sample to be age-related osteoarthritis. Similarities include metatarsal base lipping that is frequently located on the dorsal surface, metatarsal base lipping that is more severe on the lateral metatarsals compared to the medial metatarsals, and the presence of a pseudojoint between metatarsal 1 and metatarsal 2. The chance of finding an individual with osteoarthritis lipping increases from 3.45% in the age group 18-22 years to 55% in individuals over 35 years. The chance of finding a pseudojoint increases from 1.32% in non-osteoarthritic individuals to 15.15% in individuals with osteoarthritis. Results from this study indicate that the OH 8 foot bones are most likely from an adult and more likely to belong to Paranthropus boisei, the skull of which was found in the same excavations with OH 8, than to the juvenile Homo habilis holotype.
