Coronal plane lateral expandable implants

Abstract

Expandable intervertebral fusion implants, system, and methods for coronal correction. The implant may include top and bottom endplates configured to engage adjacent vertebrae, a dual actuator assembly including a rotatable drive screw actuator and a rotatable actuator nut concentric to the drive screw actuator, and driving ramps positioned along the shaft of the drive screw actuator and engaged with the top and bottom endplates via complementary ramped surfaces. When inserted in a disc space, the implant has an ipsilateral side and a contralateral side, and rotation of the drive screw actuator and/or the actuator nut causes movement of one or more of the driving ramps, thereby causing independent expansion in height of the contralateral and/or ipsilateral sides of the implant to correct the coronal deformity.
