Abstract
An interbody vertebral cage facilitates minimally invasive approaches to the intervertebral disc for corrective restoration of disc height, stabilization between vertebra, and fusion. The preferred embodiment provides a streamlined, slender straight contour with a central hinge or other articulating apparatus that allows the introduction of the cage into the operative field and disc space in a minimally invasive, bone-sparing manner. After partial insertion, the hinge component is activated, allowing the operator to steer the cage anterior-medially within the disc space to an anterior-central position within the intervertebral space. In this state the cage is shaped like a crescent, chevron or boomerang.
