Calipers, Surgical, Bone
Definition : Surgical calipers designed to measure the dimension of bones and/or eminences on bones (i.e., epicondyles) during surgical procedures. These instruments are typically handheld metallic calipers that consist of a central graduated frame, a sliding L-shaped bar or two sliding flat bars, and an auxiliary graduated scale to facilitate fine adjustment and to increase the accuracy of the measurement (i.e., vernier calipers). Bone calipers are used to measure the length, thickness, or diameter of the bones. Dedicated bone calipers are available to measure patellar thickness during patellar resurfacing procedures, to map bone ridges (usually with a central pivot and scissorslike handles), and to measure the bony ridge of the maxilla containing the alveoli (i.e., alveolar ridge calipers) during maxillofacial procedures.
