Claim:
1. An intervertebral implant configured for insertion along a lateral insertion direction into an intervertebral space defined between a superior vertebra and an inferior vertebra, the intervertebral implant comprising: a first bone contacting member having a first bone contacting surface configured to face the inferior vertebra; a second bone contacting member spaced from the first bone contacting member along a cranial-caudal direction, the second bone contacting member having a second bone contacting surface configured to face the superior vertebra, wherein the first and second bone contacting members have respective sides that are spaced apart along an anterior-posterior direction that is substantially perpendicular to the cranial-caudal direction, wherein the anterior-posterior direction and the cranial-caudal direction are substantially perpendicular to the lateral insertion direction when the implant is disposed in the intervertebral space; at least two expansion compartments that are elongate along the lateral insertion direction and disposed between the first and second bone contacting surfaces, the at least two expansion compartments being spaced apart with respect to each other along the anterior-posterior direction, each expansion compartment defining a first side, a second side spaced from the first side along the anterior-posterior direction, and a distance that extends from the first side to the second side along the anterior-posterior direction, each expansion compartment configured to expand so as to increase the distance between the first and second sides, wherein each of the at least two expansion compartments are configured to cooperate with at least one of the first and second bone contacting members to cause the expansion of the implant in the anterior-posterior direction without substantially causing the implant to expand in the cranial-caudal direction.
