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.
Claims12
An orthopaedic gauge including a means for measuring a length dimension of an elongated orthopaedic device, wherein the means for measuring includes a base portion having a fixed reference point thereon and a raised platform extending from the base portion and spaced from the reference point, wherein the raised platform includes a plurality of stops, and wherein the means for measuring further includes a means for positioning one end of the elongated orthopaedic device about the fixed reference point to enable the device to be swung through an arc about the reference point until the other of the device abuts one of the plurality of stops on the raised platform, and wherein the gauge includes a scale thereon to identify a length dimension to correspond to at least one of the plurality of stops.
An orthopaedic gauge for measuring a length dimension of an elongated orthopaedic device, wherein the gauge includes a base portion having a fixed reference point thereon and a raised platform extending from the base portion and spaced from the reference point, wherein the raised platform includes a plurality of stops, and wherein one end of the elongated orthopaedic device is positioned about the fixed 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, and wherein the fixed reference point is a single fixed reference point and wherein the raised platform has a first side spaced in one direction from the single reference point and a second side spaced in a second direction from the single reference point, different from the first direction and wherein the plurality of stops includes a first plurality of stops on the first side of the platform and a second plurality of stops on the second side of the platform, and wherein the gauge includes a scale thereon to identify a length dimension to correspond to at least one of the plurality of stops.
A method of measuring a length dimension of an elongated orthopaedic device comprising the following steps:
- a) providing an orthopaedic gauge including a base portion having a fixed reference point thereon and a raised platform extending from the base portion and spaced from the reference point, and wherein the raised platform includes a plurality of stops;
- b) positioning one end of the elongated orthopaedic device at the fixed reference point;
- and
- c) swinging the device 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.
