摘要
An implant including a cage configured to be implanted between two vertebrae, including a first deployable keel, including a first blade, a first flange extending substantially perpendicularly from a first edge of the first blade, and a second flange extending substantially perpendicularly from a second edge of the first blade, such that the cross-section of the first deployable keel is in the shape of half of an I-beam. The implant further includes a second deployable keel, including a second blade, a third flange extending substantially perpendicularly from a first edge of the second blade, and a fourth flange extending substantially perpendicularly from a second edge of the second blade, such that the cross-section of the second deployable keel is in the shape of half of an I-beam. The first keel is configured to deploy in a superior direction, and the second keel is configured to deploy in an inferior direction.
