[Clinical views on simulation and navigation technologies in kinematics of joints in locomotor surgery].

In this paper the authors give an overview of two systems (simulation and navigation) which are very important and give support to clinical work by making possible good visualization of the morphology and kinematics of joints. The approach to each patient with changes in the joints is individualized with a computer generated tomographical images which give very precise data which up to now had been inaccessible with clinical testing as the only alternative was the well known invasive diagnostic procedures. The first case concerns the COJOKS simulation system (COmputerized Joint Kinematics Simulation). The second case is of a navigation operative system which has recently been put into use and was developed on the basis of the GPS system (MSNT). This system is used for the precise determination of the bone structure of joints which is, by way of computer transformed into virtual 3D shape. This gives the surgeon all the data necessary during the operative procedure on bone and joint structures.
