A device to reduce or set malar fractures, which does not depend on the strength of the operator, comprises a stainless steel rod with a hook on one end, a handle on the other end, a movable hammer which slides freely along the rod and two stops for the hammer, one at each end of the rod. The hook is inserted under the lower edge of the malar. The force required for separating the impacted bones is produced when the hammer hits the main stop built into the rod at the end opposite the hook, stops suddenly, thereby producing a force on the hook. Since the hook is in contact with the impacted bone, the force is communicated to the bone.
