Radiographic determination of bone maturation as an aid in predicting chronologic age in the owl monkey (Aotus trivirgatus).
The skeletal development of laboratory-bred owl monkeys (Aotus trivirgatus) ranging from 37 days to 58 months of age was examined radiographically. Femoral length, time of epiphyseal ossification, and fusion of various ossification centers were studied. Chronologic age can be predicted by femoral length determination up to 18 months. Initial ossification of calcaneal, tibial tuberosity, iliac crest, and ischial apophyses occurs between 5.5 and 14 months. Fusion of various secondary ossification centers allows age determination from 7.5 months to 58 months.
