ABSTRACT:
An orthopaedic gauge 1 for measuring a length dimension of an elongated orthopaedic device, such as a screw 50, 60, or 70 or a pin or other elongated orthopaedic device. The gauge 1 includes a base portion 10 having a fixed reference point thereon, such as a raised post 12, and a raised platform 20 extending from the base portion 10 and spaced from the reference point. The raised platform 20 includes a plurality of stops 22. One end of the orthopaedic device is positioned about the reference point and the device is swung through an arc about the reference point until the other end of the device abuts one of the plurality of stops on the raised platform. A suitable scale such as 38 or 39 is provided to correspond with the plurality of stops for determining a length dimension of the device.
