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.
Claims22
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, each of the first level, the second level, and the intermediate ramp comprising a single threaded hole and collectively defining a longitudinal axis of the bone plate, 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 first and second planes extending through and parallel to the respective first and second levels, the first and second planes being substantially parallel to one another, the first level including a first threaded hole for receiving a first bone fastener, and the second level including a second threaded hole for receiving a second bone fastener, wherein the bone plate includes a third threaded hole through the intermediate ramp, each of the first threaded hole, the second threaded hole, and the third threaded hole defining a centerpoint located along a single axis.
A growth control device comprising:
- a monolithic bone plate having a stepped profile defined by a first level, a second level and an intermediate ramp connecting the first and second levels, each of the first level, the second level, and the intermediate ramp comprising a single threaded hole, 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 first and second planes extending through and parallel to the respective first and second levels, the first and second planes being parallel to one another, 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 the bone plate defining first and second washers unitarily integrated with the bone plate and surrounding the first and second threaded holes on a bone engaging surface of the bone plate.
A growth control device comprising:
- a plurality of bone plates of different sizes, each bone plate having first and second threaded holes and an intermediate portion between the first and second holes, the intermediate portion having a third threaded hole, each of the first threaded hole, the second threaded hole, and the third threaded hole defining a centerpoint located along a single axis, the plurality of bone plates including at least one stepped bone plate having first and second levels connected by the intermediate portion in the form of an angled ramp such that the first and second levels are vertically displaced from one another in separate first and second planes extending through and parallel to the respective first and second levels, the first and second planes being parallel to one another and each of the first level, the second level, and the intermediate ramp comprising a single threaded hole, and at least one arched bone plate having the intermediate portion in the form of a curved arch.
