SYSTEM AND KIT FOR CHARACTERIZING INTERVERTEBRAL DISC SPACE

摘要

A system and kit for determining at least one parameter of an intervertebral space. The system and kit may be useful to determine the appropriate size and geometry of a spinal implant. An expandable member may be inserted into an intervertebral disc space and inflated with an imaging contrast medium. The inflated expandable member and at least the intervertebral disc space may be imaged. The volume of imaging contrast medium in the expandable member may be measured in order to determine the volume of the disc space.
