Abstract
A method of assembling a system for manipulating the skeletal system includes obtaining a monolithic member having opposing ends, one end including a housing having an axially extending cavity. A distraction rod is obtained that has opposing ends, a first end having an inner threaded cavity. A rotatable, radially poled magnet is rotationally coupled to a lead screw having threads. The threads of the lead screw are engaged with the threaded cavity of the distraction rod. The magnet and at least a portion of the first end of the distraction rod are inserted into the axially extending cavity such that the distraction rod and the monolithic member are in coaxial relation to one another. The magnet is axially locked in relation to the monolithic member, wherein the axially locked magnet is capable of rotation. The distraction rod is rotationally locked in relation to the monolithic member.
