A method and a device are provided, for measuring an actual length of a fractured bone based on 2D fluoroscopic images of proximal and distal sections of the bone, each of the images including a reference body. Based on the images, a spatial position of a first end point and a spatial position of a second end point are determined, taking into account dimensions taken from a bone model of a bone corresponding to the imaged bone and the spatial positions of the reference bodies. The actual length of the fractured bone is defined as the distance between the two end points.
