Anti-retropulsion lumbar interbody device

Abstract

An anti-retropulsion lumbar interbody device has a spacer body positionable, from a posterior direction, between a first vertebrae and a second vertebrae. At least one fixation member is connected to the spacer body. The at least one fixation member is movable between a retracted position and a deployed position, wherein in the deployed position, at least a portion of the at least one fixation member extends from the spacer body to a position configured to contact the first or second vertebrae when the spacer body is positioned between the first and second vertebrae. Wherein after the at least one fixation member is in the deployed position, and when the spacer body is moved in an anterior direction, the at least one fixation member self-retracts, thereby allowing the spacer body to be removed from the position between the first and second vertebrae.
