Claim 18:
19. A distraction and retraction system comprising:
a distraction and retraction device including:
a housing having an actuator positioned therein;
a drive element coupled to the actuator and configured to rotate in response to actuation of the actuator;
a first rod configured to move in relation to the drive element and the housing in response to rotation of the drive element; and
a second rod telescopically displaceable from within a cavity of the first rod in response to rotation of the drive element,
wherein the first rod is configured to translate longitudinally along an exterior of the housing upon actuation of the actuator, wherein actuation of the actuator in one direction causes the first rod to translate along the exterior of the housing such that an overall length of the device increases, and wherein actuation of the actuator in another, opposite direction causes the first rod to translate along the exterior of the housing such that an overall length of the device decreases; and

an adjustment device configured to cause actuation of the actuator, the adjustment device positioned external to the distraction and retraction device.
