Articulated Caliper with Ruler
Vincent Y. Ng, MD
A highly precise (within 1 mm) device designed to help gauge distances between two points — can be used even if there are intervening structures like soft tissue or bone, and in situations where a straight ruler will not work
Examples of use include gauging limb length in total hip arthroplasty, confirming length in megaprosthetic knee replacements, and assessing dimensions of allografts.
