Abstract
A growth control device includes a bone plate having a stepped profile defined by a first level, a second level and an intermediate ramp connecting the first and second levels. The first level includes a first threaded hole for receiving a first bone fastener and the second level includes a second threaded hole for receiving a second bone fastener. The bone plate includes a proximal pair of side female notches, a distal pair of side female notches, a proximal guide hole and a distal guide hole.

A method, the method comprising:
- providing a bone plate having a stepped profile defined by a first level having a first aperture, a second level having a second aperture, and an intermediate ramp connecting the first and second levels, the intermediate ramp being angled relative to the first level and the second level;
- and
- anchoring the bone plate to a first bone portion with a first fastener disposed in the first aperture and to a second bone portion with a second fastener disposed in the second aperture, such that the first bone portion is vertically displaced from the second bone portion and a clearance is provided vertically between the bone plate and at least one of the first and second bone portions.
A method of correcting an angular deformity in a bone, the method comprising:
- providing a bone plate having a stepped profile defined by a first level having a first aperture, a second level having a second aperture, and an intermediate portion connecting the first and second levels;
- anchoring the bone plate to a first portion of the bone with a first fastener disposed in the first aperture and to a second portion of the bone with a second fastener;
- and
- restraining one of a medial side and a lateral side of the bone to cause the bone to grow on the other of the medial side and the lateral side, and thereby gradually correct the angular deformity in the bone.
