| Résumé : | Costo-vertebral joint (CVJ) is a structure that is mechanically involved within both respiratory function and thoracic spine stability [1]. Most of the previous experimental studies concerning CVJ provided in vitro data during loading tests [3, 4].In this paper, in vivo CT imaging data were collected for a thoracic cage in three different lung volumes (from Total lung Capacity (TLC) to Functional residual capacity (FRC)).Fusion methods were then used to register the obtained 3D rib models built from 3D anatomical model and discrete joint kinematics data to provide 3D CVJ visualisation. Helical axis (HA) representation was also obtained. CVJ displacements were interpolated between the different discrete positions including a newly-proposed rib specific anatomical coordinate system. Kinematics was processed using orientation vector position (OVP) method and helical axes computation. Results shows a specific CVJ joint model with three dimensional continuous motion simulation including HA; also simultaneous segmental movement simulation and display of HA variations was shown to be feasible. 1.
