Abstract
Systems and methods for improved cranio-maxillo-facial distraction are provided. The disclosed subject matter can include a distraction device adapted for subcutaneous implantation in a patient, and a handheld device operationally coupled to the distraction device. The distraction device can include a distraction element, adapted to attach to opposing bony fragments of a bone and perform distraction osteogenesis on the bone, and a rotatable magnetic element, coupled to the distraction element such that rotation of the magnetic element controls the distraction element. The handheld device can include a magnetic element, operationally coupled to and magnetically aligned with the magnetic element of the distraction device, such that rotation of the magnetic element of the handheld device causes corresponding rotation of the magnetic element of the distraction device. The disclosed subject matter also provides techniques for implanting a distraction device to opposing bony fragments of a bone and using such a device.
