    摘要: The present invention provides tools and methods designed to aid in the placement of facet joint prostheses at virtually all spinal levels. One aspect of the present invention is a measurement tool for installing a cephalad facet joint prosthesis including a fixation measurement element and a support arm element. This measurement tool assists in the selection and/or configuration of a cephalad facet joint prosthesis for implantation in a patient. Another aspect is a measurement tool for installing a caudal facet joint prosthesis including a stem element and a trial caudal bearing surface element. This measurement tool assists in the selection and/or configuration of a caudal facet joint prosthesis for implantation in a patient. Yet another aspect is a measurement tool holder including a measurement surface connected to a holder element. This tool holder assists in determining the measurements obtained with the caudal facet joint prosthesis measurement tool.
