A 3D mathematical model for planning ostectomy on long-bone angular deformities

This study describes a 3D mathematical model for planning a corrective ostectomy on long bones with angular deformities based on CT imaging. The use of three-dimensional information allows the model to compute and correct the bone angulation and rotation. The cutting point selection is developed minimizing the bone length reduction inherent in an ostectomy process. An example of its application on a two year old dog is shown at the end of the paper.
