Bone transport nail

An intramedullary bone transport nail, comprising:

• a nail body defining an internal chamber and defining a longitudinally elongated opening along at least a portion of the nail body;
• a first locking portion defining one or more proximal openings configured to receive one or more proximal fixation elements to fix a proximal end of the intramedullary bone transport nail within a first medullary canal of a first bone fragment;
• a second locking portion defining one or more distal openings configured to receive one or more distal fixation elements to fix a distal end of the intramedullary bone transport nail within a second medullary canal of a second bone fragment;
• a transport carriage assembly positioned within the internal chamber, the transport carriage assembly, comprising:
• a carriage body defining an axial bore and a longitudinally elongated slot along at least a portion of the carriage body, the carriage body further defining at least one radially oriented aperture aligned with the elongated longitudinal opening in the nail body, the radially oriented aperture configured to receive a transport bone segment screw;
• a threaded rod coupled to the carriage body such that the threaded rod is rotatable relative to the carriage body;
• a magnetic driver configured to be non-invasively actuated by a moving magnetic field, the magnetic driver coupled to the threaded rod such that rotation of the magnet drives rotation of the threaded rod;
• and
• a threaded block affixed to the nail body and positioned in the elongated slot of the carriage body, the threaded block defining a threaded bore therethrough, through which the threaded rod of the transport assembly is configured to pass in threaded engagement with the threaded bore such that rotation of the threaded rod relative to the threaded block causes relative axial movement between the transport carriage assembly and the nail body to translate the transport carriage assembly axially relative to the nail body.
