Abstract: A distraction device for subcutaneous attachment to vertebrae for correcting curvature of a spine is provided. The distraction device includes a housing that includes a generally hollow interior, a drive system including a drive rod operatively supported in the hollow interior of the housing and a drive element coupled to the drive rod. The drive rod is rotatable within the housing about an axis of rotation and includes a first member a second member. The distraction device includes a first extension arm operatively coupled to the first end of the housing and a second extension arm operatively coupled to the second end of the housing. Rotation of the drive rod, induced by the drive element, causes the first extension arm to move into or out from the opening at the first end of the housing in a first movement direction and the second extension arm to move into or out from the opening at the second end of the housing in a second movement direction to vary a length of the distraction device.
