Abstract
Abstract An articulated fixator for setting bones having a toggle piece to which is connected a brace piece. A pair of bars, each of which is to be fastened to a respective piece of the bone to be set, is pivotally connected to said toggle piece. A pair of stays are provided, each of which has one end pivotally connected to the end of the brace piece remote from the toggle piece. Each stay has a slot therein and a connection is made between a stay and a respective bar at a selected point along the length of the slot of a stay. In this manner two independent angles of fixation can be obtained.
