Expandable fusion devices, systems, instruments, and methods thereof. The expandable fusion implant may include an upper endplate and a lower endplate configured to engage adjacent vertebrae, an expansion gear configured to adjust a height of the upper endplate, a locking collar configured to attach to an inserter instrument at multiple orientations for a desired surgical approach, and an actuation ram configured to lock, unlock, or change insertion orientation of the locking collar. The expandable fusion device is attachable to the inserter instrument to reorient the locking collar and expand the upper endplate.
