Abstract: | Intracortical bone remodeling and cortical thickness data were collected from middiaphyseal thin sections of the humerus, ulna and tibia for 47 specimens ofSaguinus fuscicollis. Individuals were classified into age cohorts: Young Adult, Mid-adult I, Mid-adult II and Old Adult. Correlation analyses revealed significant relationships between age cohort and the number of osteons for the humerus and ulna, and between age cohort and non-Haversian canals for each of the three long bone elements. Significant relationships between age cohort and dimension of cortex size suggested an age-related pattern of cortical shifting in the ulna and older-age bone loss in the tibia. |
