Growth Plate Surgery To Help Straighten A Child's Leg

Missouri rates for HCPCS 27485

In a growing child, a small plate and screws are placed across part of a growth plate near the knee to gradually and temporarily slow growth on one side of the bone, allowing the leg to straighten over time as the rest of the leg continues to grow normally. This approach corrects bowed or knock-kneed alignment without fully stopping growth in that area.
