Abstract
A rotational correction system includes an implant having first and second sections, the implant having a rotatable permanent magnet disposed in a housing of the first section, the rotatable permanent magnet mechanically connected to a nut operatively coupled to the second section. A keyed portion is interposed between the nut and one or more non-linear grooves disposed on an inner surface of the housing. An external adjustment device having at least one rotatable magnet configured to rotate the rotatable permanent magnet of the implant is part of the system. Rotation of the rotatable permanent magnet of the implant in a first direction effectuates a clockwise change in the rotational orientation of the first section relative to the second section and rotation of the rotatable permanent magnet of the implant in a second direction effectuates a counter-clockwise change in the rotational orientation of the first section relative to the second section.

2. A method for altering rotational alignment of two sections of a patient'"'"'s bone, comprising:
-
securing a first portion of a intramedullary rotational correction device to a first section of the patient'"'"'s bone; securing a second portion of the intramedullary rotational correction device to a second section of the patient'"'"'s bone; positioning an external adjustment device in external proximity to the patient'"'"'s bone, the external adjustment device configured to activate an actuator disposed within the intramedullary rotational correction device; and operating the external adjustment device to activate an actuator of the intramedullary rotational correction device, the actuator thereby causing a rotation of the second portion of the intramedullary rotational correction device with respect to the first portion of the intramedullary rotational correction device. - View Dependent Claims (4, 6)

11. A intramedullary rotational correction device, comprising:
-
a first portion comprising a housing and configured to be secured to a first section of a patient'"'"'s bone; a second portion comprising a shaft and configured to be secured to a second section of the patient'"'"'s bone; an actuator disposed within the housing of the first portion, wherein upon an activation of the actuator the second portion rotates in relation to the first portion, thereby modifying the rotational orientation of the first section of the patient'"'"'s bone relative to the second section of the patient'"'"'s bone. - View Dependent Claims (13, 14, 15)
