Abstract
An intramedullary bone transport nail configured for axial bone segment transport by an externally applied magnetic field includes a nail body defining an internal chamber; locking portions for locking respective ends of the nail body in first and second bone fragments of a long bone, respectively; and a transport carriage assembly that is arranged in an axially movable manner within the internal chamber of the nail body and has an aperture for accommodating a transport bone segment screw for fixing a middle bone segment of the long bone to the bone transport carriage. The nail body defines an elongated longitudinal opening to allow axial motion of the transport bone segment screw as the transport carriage assembly moves axially by rotation of a threaded rod affixed to a magnetic driver. Rotation of the threaded rod is achieved by application of torque to the magnetic driver by a rotating external magnetic field.
