The present disclosure provides for spinal implants and plates including, for example, expandable plates deployable between a contracted position and an expanded position. The expandable plate may include an expandable body including a first portion and a second portion. The first portion may include a receiving cavity facing the proximal end, and a first through aperture extending in the proximal-to-distal direction. The second portion may include a lower end having a size and shape that corresponds to the receiving cavity, and a second through aperture extending in the proximal-to-distal direction. The expandable plate may include a locking screw and a nut. In at least some embodiments, in a locked position, the locking screw extends through the first through aperture and second through aperture, and is secured to the nut. In various embodiments, in an expanded position the first portion and second portion are farther away from one another relative to a contracted position.
