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.

Abstract: Systems for positioning a patient are provided. A patient positioning system comprising: an upper support comprising: a mounting plate for a pad; a hinge comprising a curved surface including teeth, the curved surface operable to rotate; a pawl that is in contact with the teeth of the hinge, wherein the pawl is operable to allow rotation of the pad in a first direction due to angles of the teeth; a moveable member extending from the hinge, the moveable member including teeth; and a second pawl that is in contact with the teeth of the moveable member, the second pawl operable to allow movement of the moveable member due to angles of the teeth of the moveable member; and a lower support connected to the upper support via the moveable member.

Abstract: Systems for positioning a patient are provided. A patient positioning system comprises a set of break assemblies, each break assembly comprising a mount for receiving padding, wherein each break assembly is operable to independently rotate to provide a coronal break relative to a longitudinal axis of the frame; and a set of tilt assemblies mounted to the frame, each tilt assembly operable to independently tilt relative to a longitudinal axis of the frame, wherein the break assemblies are mounted to the tilt assemblies.
