摘要： Methods for detecting positional movement of orthopedic implants are described herein. In one embodiment, the method may include receiving a two-dimensional image defining an image plane, the two-dimensional image capturing a reference marker received within the bone and an orthopedic implant received within a bone, calculating a first angle of the reference marker relative to the image plane based on previously stored dimensions of the reference marker, calculating a second angle of the orthopedic implant relative to the image plane based on previously stored dimensions of the orthopedic implant, comparing the first angle to the second angle to calculate a current angle of rotation, and comparing the current angle of rotation to a previously calculated angle of rotation to detect rotation of the orthopedic implant relative to the bone.
