Abstract

An apparatus for use in an arrangement for measuring the relative position of two bones during surgery includes a clamp and a measurement arm. The clamp is adapted to engage and secure to an anchor in a fixed vertical position, the anchor being secured to a first bone location. The measurement arm comprises an elongate portion and a locator portion that extends angularly from the elongate portion. The measurement arm is slidably supported on the clamp. The measurement arm is further rotatably supported on the clamp at a position in which an axis of rotation of the measurement arm is spaced apart from a longitudinal axis of the anchor.
