<p>A spinal construct (16) and method for implantation is provided which utilizes a spinal implant (17) adapted for insertion within an intervertebral space between an adjacent pair of vertebral bodies (11, 12), and an elongate member (26) adapted for anchoring to the adjacent vertebral bodies (11, 12). The spinal implant (17) defines a first transverse dimension (A) and a different second transverse dimension (B), and is initially inserted into the intervertebral space while in a first operational configuration wherein the first transverse dimension (A) extends along the height of the intervertebral space. The elongate member (26) is anchored to the vertebral bodies (11, 12) to establish and maintain a select height of the intervertebral space. The spinal implant (17) is then rotated to a second operational configuration wherein the second transverse dimension (B) extends along the height of the intervertebral space. The elongate member (26) serves to maintain the select height of the intervertebral space to provide a controlled amount of compression onto the spinal implant (17) and/or a bone growth promoting material contained therein. The elongate member (26) also serves to resist tensile loads during extensional movement of the vertebral bodies (11, 12) to maintain the vertebral endplates in intimate contact with the spinal implant (17).</p> |
