INTERVERTEBRAL DISC SPACE SIZING TOOLS AND METHODS
摘要
<p>A method and apparatus for making a size measurement within an intervertebral space by placing an expandable and contractible device into the intervertebral space, expanding the device, measuring a size characteristic of the space, contracting the device and then removing it. The measurement may be accomplished by an external x-ray or other imaging device imaging the expanded device in situ or by mechanically operated devices. An apparatus and method is provided for the measuring of the intervertebral space at a controlled distraction force. The apparatus includes an expandable device for providing a measurement within the intervertebral space and facilitating the measurement of the angulations of the lordotic curve of the intervertebral space.</p>
