SPREADING AND CONTRACTING TOOL FOR KNEE OSTEOTOMIES

摘要

A tool for spreading and contracting a bone along a cut formed therein as part of a knee osteotomy procedure is provided. The spreading tool includes an upper arm and a lower arm respectively extending along a length between an effort end and a load end, the arms being pivotally connected to one another via a hinge positioned between the effort and load ends; and an anchor interface proximate the load ends for anchoring the load ends of the arms relative to respective first and second fixed positions on the bone. The tool being operable, via rotation of the arms about the hinge, between a closed configuration in which the load ends of the upper and lower arms are proximate one another and an open configuration in which the load ends of the upper and lower arms are spaced apart from one another.
