Patent ID: 8273111

Claim:
A growth control device comprising: 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 intermediate ramp being angled relative to the first level and the second level such that the first and second levels are vertically displaced from one another in separate planes, the first level including a first threaded hole for receiving a first bone fastener, the second level including a second threaded hole for receiving a second bone fastener, the bone plate including a proximal pair of side female notches, a distal pair of side female notches, a proximal guide hole and a distal guide hole; and a holding device including first and second pivotably coupled arms, first and second legs extending from the corresponding first and second arms, a guiding bore defined between the first and second legs, and a curved split slot defined by a distal end of each of the first and second legs and shaped to receive one of a proximal end or a distal end of the bone plate, the split slot defining a split hole at a perimeter of the first and second legs so as to coextend with the guiding bore.
