Abstract
Methods of performing opening wedge osteotomies are disclosed in which healing of the osteotomy defect is enhanced by packing the opening with pre-packaged, wedge-shaped bone grafts. The bone wedges are provided in sets of three: two larger outer pieces and a smaller inner piece that fits behind a bone plate. The wedge pieces are made of allograft bone or synthetic bone material. Outer surfaces of the two larger pieces preferably are cortical bone or cortical bone-like material.
