Abstract
An articulated tensioning device includes a first foot and a second foot. One of the feet includes a projection configured to engage a fastener hole of a bone plate and the other of the feet includes a hole therethrough for receiving a fastener. The device also includes a slider translatable relative to the first foot and a bridge link pivotably connected to the slider at a first point pivotably connected to the second foot at a second point. A fulcrum link is pivotably connected to the second foot and a third point on the bridge link that is between the first point and the second point.
