摘要：
A method for measuring the displacements of a vertebral column includes: an initial step, for each vertebra in a segment, including: detection of an initial orientation of the location marker associated with the vertebra, determination of an initial orientation of a vertebral plane parallel to at least one end plate of the vertebra, and a calculation of a geometric transformation associated with the vertebra correlating the initial orientation of the vertebral plane of the vertebrae with the initial orientation of the location marker associated, and； a step measuring displacement of at least one vertebra, including: detection of the current orientation of the location marker associated with the at least one vertebra, and a calculation of the current orientation of the vertebral plane of the at least one vertebra from the current orientation of the location marker associated and the geometrical transformation associated with the at least one vertebra.
