4. It is related with method about providing that ithe obtained parameters are sent to the software calculating the change of rod lengths actordihg to claim 1, it is characterized by that radiography model can be turned (3) for ensuring that radiography image and model match with each other to determine the coordinate of the bone axes after the roentgen images are taken and to ensure that they are correlated with the position of the fixator.
5. It Is related with method about providing that the; obtained parameters are sent to the software calculating the change of rod lengths according to claim 1, it is characterized by that the length and width of the radiography image can be changed together or separately (4) for ensuring that radiography image and model match with each other to determine the coordinate of the bone axes after the roentgen images; are taken and to ensure that they are correlated with the position of the fixator.
6. It is related with method about providing that the (obtained parameters are sent to the software calculating the change of rod lengths according to claim 1, it is characterized by that radiography image can be shifted vertically 6r horizontally on the coordinate plane (5) for ensuring that radiography image and model match with each other to determine the coordinate of the bone axes after the roentgen images are taken and to ensure that they are correlated with the position of the fixator.
7. It is related with method about providing that the obtained parameters are sent to the software calculating the change of rod lengths according to claim 1, it is characterized by that the axis is determined from the middlafizel poirit of the bone (6) to determine the coordinates of the bone segments connected to top and bottom circle after the radiography image is matched with the model in the coordinate plane.
8. It is related with method about providing that i the obtained parameters are sent to the software calculating the change of rod lengths aqcordi.ng to claim 1, it is characterized by that it is possible that the medium point can be calculated by the software {7) by selecting two external points of the bone as one of the twd methods to be used for determining the middiafizel point.
