摘要： The present invention provides an expandable intervertebral implant that is selectively disposed in the intervertebral space and deployed, thereby in-situ distracting, realigning, and/or stabilizing or fusing a portion of the spine of a patient in the treatment of injury, disease, and/or degenerative condition. The expandable intervertebral implant includes a superior member and an inferior member, each of which has a partially or substantially wedge or prismatic shape and a partially or substantially convex or other-shaped surface that is suitable for engaging the substantially concave surfaces of the associated bony superior and inferior intervertebral endplates. Once disposed in the intervertebral space, the expandable intervertebral implant is actuated and deployed, with the superior member and the inferior member moving apart from one another, seating against the associated intervertebral endplates, and distracting, realigning, and/or stabilizing them to a desired degree. The external surface of each of the superior member and the inferior member is provided with a plurality of ridges or other friction structures, providing purchase with the associated intervertebral endplates.

摘要： An expandable intervertebral implant, including a superior and inferior members configured to engage a superior and inferior intervertebral body, and an expansion mechanism disposed between the members to selectively adjust separation between them. The expansion mechanism includes a proximal wedge structure and a distal wedge structure that are relatively translated between the superior and inferior members. The wedge structures are coupled to the superior and inferior members by a plurality of track structures and rail structures. The superior and inferior members are configured to mate vertically when the expansion mechanism is undeployed via conformal protruding and recessed features.
