Abstract
Methods and apparatus for performing an osteotomy. One embodiment includes a kit comprising a bone plate, a bridging device, and a spreading device. The bridge is configured to hold open the incision in the bone, whether the spreading device is inserted into the bone, or the bone plate is attached to the bone. The spreading device preferably includes a scissors-type mechanism for spreading two wedge-shaped members apart, contemplating both pivotal and displacement movements of one wedging member relative to another wedging member. The spring device preferably includes an ergonomic grip for the hand of the physician, and a hammering surface useful in inserting the spreading device into the incision.
