摘要:
A method of controlling a surgical intervention to a bone (31) comprises: obtaining a three-dimensional image or multiplanar reconstruction of the bone (31), defining a position and an axis of intervention on the three-dimensional image or multi-planar reconstruction of the bone (31), and controlling the orientation of an intervention instrument (1) equipped with an orientation sensor (2) during the surgical intervention by evaluating a signal provided by the orientation sensor (2). The method further comprises referencing the intervention instrument (1) with respect to the bone (31) before the surgical intervention by arranging the intervention instrument (1) along an anatomic landmark (32) being an edge of the bone (31) and rotating the orientation sensor (2) into a predefined position, or by arranging the intervention instrument (1) essentially perpendicular to an anatomic landmark (32) being an essentially flat surface of the bone (31) and rotating the orientation sensor (2) into a predefined position. The method according to the invention allows for efficiently achieving correct orientation and position of the intervention instrument in a bone surgical intervention. Furthermore, the method according to the invention provides an efficient real-time control at comparably low efforts. Still further, with the method according to the invention radiation exposure to the operational staff as well as patients can be reduced.
