Abstract: | This work focuses on the influence of locomotor loads on the trabecular architecture of primate proximal femora. A sample of extant primates was used as a comparative base to analyze the trabecular architecture of two Miocene hominoidean species with regard to their habitual hind limb loading. Thereupon, conclusions on the preferred locomotor strategy of the fossil species were drawn. This study is preconditioned by the fact that bones possess the ability of functional, load directed adaptation, and that specific loads are applied on the femur during distinct locomotor modes. These loads are dependent upon body weight and muscle activity (PAUWELS 1965, DUDA 1996). Different types of locomotion induce different femoral loading, due to the multiple positions of the bodies center of gravity and the various muscles which contract in each phase of locomotion. Therefore, it is hypothesized here that habitual loads which act upon the femur influence the trabecular architecture and therefore the trabecular architecture permits a discrimination of varying locomotor habits. To obtain accurate 3D data of the proximal femoral trabecular architecture, the specimens were imaged with high resolution computed tomography (CT). Based on these 3D images, the trabecular architecture was structurally described and the features of the trochanter minor region were histomorphometrically analyzed to quantify their characteristics. FEM (Finite Element Method) analyses of models obtained by high resolution (CT) 3D data were conducted and demonstrated the prerequisites for correct simulation of femoral loading conditions in trabecular bone. The results of the histomorphometric analysis and the structural description of the extant primate sample yielded architectural models of cancellous bone which correspond to their different locomotor behaviors. The same results of the fossil sample were then compared with the extant primate models. This allowed an estimation of the locomotor preferences of the fossil species. Further research on skeletal mechanics and locomotion will improve and refine the analysis of architectural features in cancellous bone. By focusing on internal bony morphology, this study offers a new method which can be used in concert with the classical analysis of locomotor behavior, which relies on external bony morphology. The applied method will also improve the biomechanical analysis of fragmentary fossil material. This work obtained further insight into the functional adaptation of cancellous bone on applied loads and provided information which can be used in pursuing basic research. |
