<p>PURPOSE: An expansion gage between the vertebral bodies is provided to enable an operator to easily insert a gage between the vertebral bodies by expanding the size of the cage by using a sliding member in a state in which the cage is installed between the vertebral bodies. CONSTITUTION: An expansion gage (100) between the vertebral bodies expands the space between the vertebral bodies. An upper supporting unit (120) supports the vertebral bodies located on the upper part of the vertebral bodies. A lower supporting unit (130) supports the vertebral bodies located on the lower part of the vertebral bodies. A cage body (110) includes a connecting unit connecting the upper supporting unit and the lower supporting unit. A sliding member (170) reduces or increases a gap between the upper supporting unit and the lower supporting unit.</p> |
