    Abstract: A variable length nail is provided with at least 5 mm of axial length change in each direction. An external adjustment device having at least one rotatable magnet is placed in proximity to the patient's skin. The external adjustment device is operated so that a magnetic field of the at least one rotatable magnet of the external adjustment device causes the rotatable permanent magnet of the variable length nail to rotate, causing either extension or retraction of the distraction shaft relative to the housing. In another embodiment, a rotational correction system is provided in which the bone implant has first and second sections that rotate with respect to one another in response to a magnetic field applied by the external adjustment device. In this regard, rotational adjustment of two bone sections may be accomplished.
