ABSTRACT:
A device and a method related to performing a pelvic osteotomy. A fixation bracket including dual planar plate members joined rigidly at their marginal edges by a web member makes possible the fixation of ilial sections in a desired angular and positional relationship. Elongate holes in each plate member include beveled features that allow the bracket, when secured by screws, compressibly to urge the two ilium sections toward one another normal to the plane of a cut therebetween. In a modification, the angle formed by the web member between the two plate members is adjustable by a surgeon in a range around its nominal value. The improved osteotomy method made possible by the fixation bracket includes offsetting of the ilial section away from the pelvic canal, before its rotated rejoining with the pelvis from which it was separated.
