Abstract
A spinal implant for placement between vertebral bodies includes a first member for engaging one of the vertebral bodies, a second member for engaging an opposing one of the vertebral bodies, and at least one extendable support element for inducing movement of the entire first member away from the second member. The first member is connected to the second member such that the first member moves away from the second member by a larger distance at a first end of the implant than at a second end of the implant. A connecting member may connect the first and second members together at the second end of the implant. The connecting member may include one or more rotatable linkages, or the connecting member may be an extension of one of the first and second members slidably received within a track defined within the other of the first and second members.
Claims (10)
1 . A method of performing interbody fusion, the method comprising:
positioning a spinal implant between a first vertebral body and a second vertebral body, wherein the spinal implant includes a first member having a first surface for engaging the first vertebral body and a second member having a second surface for engaging the second vertebral body;
actuating one or more extendable support elements connected between the first and second members such that each of the one or more extendable support elements extends at the same rate with at least one of the extendable support elements actuated by a fluid; and
inducing, based on the actuation of the at least one extendable support element, movement of the entire first member away from the second member at both a first end portion and a second end portion of the spinal implant, wherein the induced movement of the first member away from the second member is guided by a linkage, such that the first member moves away from the second member by a larger distance at the first end portion of the implant than at the second end portion of the implant.
2 . The method of claim 1 , wherein the linkage is positioned at the second end portion of the implant such that the induced movement of the linkage guides the first member away from the second member by constraining the movement of the first member at a second end of the implant.
3 . The method of claim 1 , wherein the at least one extendable support element is located at the first end portion of the spinal implant.
4 . The method of claim 1 , further comprising inducing, based on the actuation of the at least one extendable support element, movement of the linkage.
5 . The method of claim 1 , wherein the linkage is a rotatable linkage having a first end and a second end, the first end of the linkage being pivotably connected to the first member and the second end of the linkage being pivotably connected to the second member.
6 . The method of claim 1 , wherein the linkage is a rotatable linkage.
7 . The method of claim 1 , wherein the linkage is configured such that the first member rotates about a point spaced apart from the implant proximate the second end portion of the implant.
