Patent attributes
Expandable spinal implants, systems and methods are disclosed. An expandable spinal implant may include a proximal end plate, a superior endplate, an inferior endplate, and a moving mechanism that is operably coupled to the superior and inferior endplates. The proximal end plate may include at least one bone screw aperture configured to orient a bone screw across a bone screw relief of the superior endplate and/or inferior endplate. The moving mechanism may include a wedge, a first sliding frame, a second sliding frame, a screw guide housing a rotatable first set screw and a rotatable second set screw. A spacing between the superior and inferior endplates may be adjusted upon simultaneous rotation of the first and second set screws and an angle of inclination between the superior and inferior endplates may be adjusted upon translating either of the first set screw and second set screw.
