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 top plate including a first surface to engage the first vertebral body, a housing including a second surface to engage the second vertebral body, and a hydraulic system between the top plate and the housing; and
inducing, based on an actuation force to the hydraulic system, movement of the top plate away from the housing at both a first end portion and a second end portion of the spinal implant, wherein
the induced movement of the top plate away from the housing is guided by a linkage, such that the top plate moves away from the housing by a first distance at the first end portion of the implant and a second distance at the second end portion of the implant, and
the first distance is greater than the second distance.
