Customized Bone Distraction Method, Device and System

A bone distraction method comprising the steps of:

• creating a virtual three-dimensional model of a bone to be distracted using computer-aided design;
• determining desired affixation locations on the virtual three-dimensional model for a first bone plate and a second bone plate and determining a desired distraction vector;
• creating a virtual three-dimensional template of the first bone plate and a virtual three-dimensional template of the second bone plate such that the inner surface of the virtual three-dimensional first bone plate template conforms to the surface topography of the bone at the desired attachment location for the virtual three-dimensional first bone plate template on the virtual three-dimensional model and the inner surface of the virtual three-dimensional second bone plate template conforms to the surface topography of the bone at the desired attachment location virtual three-dimensional second bone plate template on the virtual three-dimensional model;
• determining the desired osteotomy location on the bone, and creating a virtual guide edge defining the desired osteotomy location on at least one of the virtual three-dimensional first bone plate template and second bone plate template;
• creating a first bone plate based on the virtual three-dimensional first bone plate template and a second bone plate based on the virtual three-dimensional second bone plate template, the inner surfaces of each bone plate conforming to the exterior surface of the bone at the affixation location and the guide edge defining the osteotomy location on the bone;
• providing a distraction mechanism, wherein the first bone plate and the second bone plate are releasably attachable to the distraction mechanism to create a distractor device such that the distraction mechanism is oriented in the desired distraction vector when the distractor device is affixed to the bone;
• attaching the first bone plate and the second bone plate to the distraction mechanism;
• affixing the first bone plate and the second bone plate to the bone;
• detaching the distraction mechanism from the first and second bone plates;
• performing an osteotomy on the bone using the guide edge to create a first bone segment and a second bone segment wherein the first bone plate is affixed to the first bone section and the second bone plate is affixed to the second bone segment;
• and
• re-attaching the bone distractor to the first and second bone plates and incrementally distracting the bone segments during osteogenesis.
