Dual expanding spinal implant, system, and method of use

An expandable and contractable spinal implant, comprising:

• an expandable body extending from a proximal end to a distal end in a proximal-to-distal direction, extending from a first lateral side to a second lateral side in a widthwise direction, and extending from a superior end to an inferior end in a vertical direction, the expandable body being defined by a superior endplate and an inferior endplate opposite the superior endplate, the expandable body including a beveled hook portion at a distal end thereof;
• the superior endplate including a first outside surface and a first inside surface opposite the first outside surface, the first inside surface including first proximal ramps and first distal ramps disposed opposite the first proximal ramps;
• the inferior endplate including a second outside surface and a second inside surface opposite the second outside surface, the second inside surface including second proximal ramps and second distal ramps disposed opposite the second proximal ramps;
• a support frame coupled to the superior endplate and the inferior endplate, the support frame having a proximal screw guide and a distal screw guide opposite the proximal screw guide, the proximal screw guide defining a first rotation axis and the distal screw guide defining a second rotation axis, the first and second rotation axes extending in the proximal-to-distal direction;
• a proximal set screw rotatably supported by the proximal screw guide and a distal set screw rotatably supported by the distal screw guide;
• a proximal wedge coupled to the proximal set screw and including first superior ramped surfaces and first inferior ramped surfaces, and a distal wedge coupled to the distal set screw and including second superior ramped surfaces and second inferior ramped surfaces,
• wherein:
• the proximal wedge and distal wedge are configured to simultaneously distract the superior and inferior endplates in a parallel manner upon simultaneous rotation of both the proximal set screw and distal set screw in a first direction and simultaneously contract the superior and inferior endplates in a parallel manner upon simultaneous rotation of both the proximal set screw and distal set screw in a second direction opposite the first direction.
