Abstract: The bone plate (1) has a lower surface (2), an upper surface (3), a thickness T measured between the lower and upper surfaces (2;3), a longitudinal axis (4) and a plurality of plate holes (5) running from the lower surface (2) to the upper surface (3). The bone plate (1) further has a slot (6) extending from the lower surface (2) towards the upper surface (3) and having a width W measured at the lower surface (2) and parallel to the longitudinal axis (4). The slot (6) extends to a maximum distance D measured from the lower surface (2) towards the upper surface (3) of 0.4-0.9 times the thickness T of the bone plate (1). The slot (6) has a width measured parallel to the longitudinal axis (4) which at its maximum extension E is at least 0.8 mm, preferably of at least 3 mm. The slot (6) allows the plate (1) to bend longitudinally—additionally to the intrinsic bendability of the unslotted plate (1)—at most to the amount of 20°, preferably at most to the amount of 10°.

Abstract: A method for generating a 3D reference computer model of at least one anatomical structure for comparison with a selectable pre-, intra- or postoperative set of medical images of at least one anatomical structure, the method including: acquiring at least a first and a second medical image of at least one anatomical structure in a preoperative status from different perspectives using a computer assisted medical imaging device, wherein the first and second medical images are represented by a respective first and second set of digital 2D image data; and generating a 3D reference computer model of an anatomical structure by selecting and extracting a 3D atlas model of an anatomical structure to be treated from a generic anatomical atlas provided in the form of a digital data source, and registering at least a section of each of the first and second medical images to the selected 3D atlas model.

Abstract: A method for generating a graphical 3D computer model of anatomical structures in a selectable pre-, intra-, or postoperative status that includes: (A) receiving a preoperative first medical 3D image data set of anatomical structures to be treated of a patient; (B) generating a first graphical 3D computer model of the anatomical structures to be treated in the form of a digital data set using the data received in step (A); (C) receiving a second medical 2D or 3D image data set of the anatomical structures to be treated; (D) generating a second graphical 2D or 3D computer model of the anatomical structures to be treated in the form of a digital data set using the data received in step (C); and (E) carrying out an image registration process of the first graphical 3D computer model using the second graphical 2D or 3D computer model.
