Abstract
One aspect of the disclosure relates to an extramedullary distraction and compression system. The extramedullary distraction system includes: a housing configured to be attached to a bone at a first location, the housing having a magnet and a lead screw positioned therein, wherein the lead screw is coupled to the magnet such that rotation of the magnet causes rotation of the lead screw, at least one retainer clip disposed around the lead screw; a rod configured to be attached to the bone at a second location and configured to interact with the lead screw such that, upon rotation of the lead screw, the rod distracts or contracts relative to the housing.

An extramedullary distraction and compression system comprising:
- a housing configured to be attached to a bone at a first location, the housing having a magnet positioned therein;
- a rod configured to be attached to the bone at a second location and comprising a lead screw therein, wherein the lead screw comprises a keyed outer surface at an end proximate the magnet and is coupled to the magnet such that rotation of the magnet causes rotation of the lead screw, and the rod is configured to interact with the lead screw such that, upon rotation of the lead screw, the rod distracts or contracts relative to the housing;
- and
- at least one retainer clip disposed around the lead screw, wherein a portion of the lead screw proximate the end with the keyed outer surface includes at least one recess and the at least one retainer clip is disposed within the at least one recess of the lead screw.
