An interbody spacer includes concave lateral surfaces extending at an angle with respect to the longitudinal axis. In one aspect, the interbody spacer includes upper and lower convex surfaces defined by an arc extending from a center point offset from the spacer midpoint. In another aspect, lateral edges of the upper and lower surfaces are also defined by convex arcs extending from a center point offset from the spacer midpoint.
