An interbody implant for implanting in an intervertebral space surrounded by adjacent vertebral bodies in a patient during spinal fusion, said implant comprising: a plurality of elongate members (20; 40; 70; 100; 210; 201; 209; 211) that form the implant, the plurality of elongate members having superior and inferior surfaces with a height therebetween, and medial and lateral surfaces having a width therebetween, wherein the superior and inferior surfaces are shaped to engage the vertebral bodies, and wherein the height is set at a predetermined distance that is sized to fit into the intervertebral space, and wherein the width is set at a predetermined distance less than the predetermined height, and wherein the interbody implant has a first configuration, a second configuration, and a third configuration, wherein the interbody implant is designed to be inserted into the intervertebral space in the first configuration such that medial and lateral surfaces contact the vertebral bodies, to be actuated from the first configuration into the second configuration such that superior and inferior surfaces engage the vertebral bodies, wherein actuation of the implant from the first configuration to the second configuration distracts the vertebral bodies away from one another to increase the intervertebral space, and to be actuated into the third configuration where the width of the implant is greater than width of the interbody implant in the first or the second configuration, wherein the plurality of elongate members (20; 40; 70; 100; 210; 201; 209; 211) is coupled together with a first spanning component (30; 50; 80; 110; 175; 202; 212) that faces in a first direction and a second spanning component (30; 50; 90; 110; 175; 202; 212) that faces in a second direction opposite the first direction. a plurality of elongate members (20; 40; 70; 100; 210; 201; 209; 211) that form the implant, the plurality of elongate members having superior and inferior surfaces with a height therebetween, and medial and lateral surfaces having a width therebetween, wherein the superior and inferior surfaces are shaped to engage the vertebral bodies, and wherein the height is set at a predetermined distance that is sized to fit into the intervertebral space, and wherein the width is set at a predetermined distance less than the predetermined height, and wherein the interbody implant has a first configuration, a second configuration, and a third configuration, wherein the interbody implant is designed to be inserted into the intervertebral space in the first configuration such that medial and lateral surfaces contact the vertebral bodies, to be actuated from the first configuration into the second configuration such that superior and inferior surfaces engage the vertebral bodies, wherein actuation of the implant from the first configuration to the second configuration distracts the vertebral bodies away from one another to increase the intervertebral space, and to be actuated into the third configuration where the width of the implant is greater than width of the interbody implant in the first or the second configuration, to be inserted into the intervertebral space in the first configuration such that medial and lateral surfaces contact the vertebral bodies, to be actuated from the first configuration into the second configuration such that superior and inferior surfaces engage the vertebral bodies, wherein actuation of the implant from the first configuration to the second configuration distracts the vertebral bodies away from one another to increase the intervertebral space, and to be actuated into the third configuration where the width of the implant is greater than width of the interbody implant in the first or the second configuration, wherein the plurality of elongate members (20; 40; 70; 100; 210; 201; 209; 211) is coupled together with a first spanning component (30; 50; 80; 110; 175; 202; 212) that faces in a first direction and a second spanning component (30; 50; 90; 110; 175; 202; 212) that faces in a second direction opposite the first direction.
