1. A guided bone growth plate configured for tethering the physis of a subject, comprising at least two plate segments, each plate segment attachable to bone;
the guided bone growth plate having
(i) a locked position in which the plate segments are connected by a connector mechanism so that the plate segments are in a fixed, spaced apart relation to one another along a longitudinal axis, the plate segments configured for tethering the physis to reduce physeal bone growth; and
(ii) an unlocked position in which the plate segments are fully disconnected such that the plate segments are configured to move apart along the longitudinal axis only in response to bone growth;
a magnetically responsive driver on at least one of the plate segments, the driver capable of being actuated by application of magnetic force to the driver to disconnect the connector mechanism to change the plate from the locked position to the unlocked position.
