摘要： An expandable intervertebral implant for insertion between vertebrae of a human spine is described. The intervertebral implant includes an upper body that engages a first vertebra of the human spine, a lower body that engages a second vertebra of the human spine, an insert, and an advancing element. The advancing element may engage the insert such that advancement of the advancing element causes the insert to at least partially rotate between the upper body and the lower body. Rotation of the insert may cause the insert to interact with at least a portion of the upper body or at least a portion of the lower body to increase a separation distance between the upper body and the lower body, thereby increasing a height of the intervertebral implant after insertion of the implant between the first vertebra and the second vertebra of the human spine.

摘要： An articulating expandable intervertebral implant for insertion between vertebrae of a human spine is described. The articulating expandable intervertebral implant includes an upper body that engages a first vertebra of the human spine, a lower body that engages a second vertebra of the human spine, and an elongated member. The superior surface of the lower body includes a channel. A portion of the inferior surface of the upper body may be substantially concave. The elongated member may include a cam portion along a length of the elongated member. The elongated member may be positioned in the channel of the lower body. The substantially concave portion of the upper body may contact the elongated member, such that rotation of the elongated member about a longitudinal axis of the elongated member increases a height and/or increases articulation of the intervertebral implant after insertion of the intervertebral implant.

摘要： An expandable intervertebral implant for insertion between vertebrae of a human spine is described. The expandable intervertebral implant includes an upper body that engages a first vertebra of the human spine, a lower body that engages a second vertebra of the human spine, an insert, and a spacer. The insert may be positioned between an inferior surface of the upper body and a superior surface of the lower body. The insert may be engaged to increase a separation distance between the lower body and the upper body. A spacer may be inserted between the upper body and the lower body to maintain the increased separation distance between the upper body and the lower body after expansion of the intervertebral implant in the human spine.
