Claim:
1. An apparatus for recording a first anatomical position of a selected body part of a patient, comprising: (a) an attachment device, wherein the attachment device couples to at least one selected body part of the patient; (b) a measuring device, comprising a gyroscope, an inclinometer, or a combination thereof, wherein the measuring device measures the orientation of a first anatomical position of the selected body part relative to a known landmark within the body of the patient; (c) a connector that couples the measuring device to the attachment device, and (d) at least three non-collinear fiducial markers that are operably positioned relative to the connector at predetermined fixed distances and predetermined fixed angles relative to each other to define a three-dimensional space; wherein the measuring device is orthogonal to the three, non-collinear fiducial markers, and further wherein the orientation of the first anatomical position of the selected body part is measured three-dimensionally using pitch, yaw, and roll data obtained from the measuring device.
