摘要:
A laterovertically expandable scaffolding is provided for supporting an intervertebral disc space using a minimally invasive procedure. The scaffolding can be configured to provide a low-profile entry in a collapsed configuration through the single point of entry through the annulus. The expanding including laterally expanding at least a portion of a first support and at least a portion of a second support away from each other and, vertically expanding at least a portion of the first support or at least a portion of the second support for a distraction of the intervertebral space. The lateral movement can include a rotation at a point of intersection between the first support and the second support, the intersection being biased anteriorly in the intevertebral space to facilitate the adding of the grafting material.
