Adaptable interbody implant and methods of use

An intervertebral fixation implant comprising:

• a body defining a longitudinal axis and extending between a first end and a second end, the body defining a first wall configured for engaging a first vertebral surface and a second wall configured for engaging a second vertebral surface, the first wall being connected to the second wall such that the walls extend from the first end in a cantilevered configuration,
• the first wall defining an arcuate inner surface and the second wall defining an arcuate inner surface, the inner surfaces defining a deformation cavity and the walls being configured to collapse in the cavity such that the body selectively deforms in a range between a spaced apart distance between the walls and engagement of the walls,
• wherein 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 surface geometry and height of an intervertebral space between the first vertebral surface and the second vertebral surface.

An intervertebral fixation implant comprising:

• a body defining a longitudinal axis and extending between a first end and a second end, the body defining a first wall configured for engaging a first vertebral surface and a second wall configured for engaging a second vertebral surface, the walls including a first pair of lateral arms and a second pair of lateral arms, each of the pair of lateral arms extending between the first end and the second end and defining a cavity therebetween, the arms being configured to collapse in the cavities during deformation,
• each of the pair of arms including at least one post disposed therebetween, the at least one post extending a first distance,
• wherein the first wall is movable relative to the second wall such that the body is selectively deformable from
• a first, initial implanted configuration such that the walls are spaced apart a second distance, the second distance being greater than the first distance, and 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 selectively deformed according to a difference between the first distance relative to the second difference to adapt to an orientation of the first vertebral surface and the second vertebral surface.
