A method of controlling a surgical intervention to a bone comprises obtaining a three-dimensional image or multiplanar reconstruction of the bone, defining a position and an axis of intervention on the three-dimensional image or multiplanar reconstruction of the bone, and controlling an orientation of an intervention instrument equipped with an orientation sensor during the surgical intervention by evaluating a signal provided by the orientation sensor. The method further comprises referencing the intervention instrument with respect to the bone before the surgical intervention by arranging the intervention instrument in relation to an anatomic landmark and rotating the orientation sensor into a predefined position. The method allows for efficiently achieving correct orientation and position of the intervention instrument in bone surgical intervention. Furthermore, the method provides an efficient real-time control at comparably low efforts. Still further, with the method radiation exposure to the operational staff as well as patients can be reduced.
