Abstract: A measuring instrument configured to measure a bone and a plate to determine the size of an attachment clamp, including: a medial clamp configured to engage a medial portion of the bone; a medial gauge connected to the medial clamp, the medial gauge including: a key along a portion of the medial gauge adjacent the medial clamp; a gauge indicator configured to indicate the size of attachment clamp; and a threaded portion; a lateral clamp configured to engage a plate on the bone, where the lateral clamp has a hollow portion with a channel, wherein the gauge indicator is positioned in the hollow portion and wherein the channel is configured to engage the key of the gauge indicator to prevent the lateral clamp from rotating about the gauge indicator; and a tightening knob threaded onto the thread portion of the of the medial gauge, wherein one end of the tightening knob indicates on the gauge indicator the size of the attachment clamp.
