An intervertebral fusion implant comprises a body defining a longitudinal axis and extending between a first end and a second end. The body defines a first wall configured for engaging a first vertebral surface and a second wall configured for engaging a second vertebral surface. The first wall is connected to the second wall. The first wall is movable relative to the second wall such that the body is deformable from a first, initial implanted configuration such that the body is disposed between the first vertebral surface and the second vertebral surface for fixation thereof and a second configuration such that the body is deformed relative to the first configuration to adapt to an orientation of the first vertebral surface and the second vertebral surface. Methods of use are disclosed.
