Abstract: Expandable fusion devices, systems, instruments, and methods thereof. The expandable fusion implant may include upper and lower endplates configured to engage adjacent vertebrae and an actuator assembly for expanding the upper and lower endplates. An insertion and expansion instrument includes outer and inner drivers, which allow the surgeon to independently control parallel and lordotic expansion of the implant.

Abstract: Disclosed herein are an inserter instrument, a system including the inserter, a spinal implant, and fasteners for affixing the implant to the spine of a subject, and related methods for performing spinal procedures including insertion of spinal plates. The inserter includes a housing, an inner sleeve slidably disposed within the housing, and an awl slidably disposed within the housing and inner sleeve. The housing includes a rotatable portion configured to actuate translation of the inner sleeve proximally or distally relative to the housing along a central axis to releasably engage the spinal implant using a distal engagement portion of the inner sleeve. The awl is configured to form a pilot hole in a vertebra at the surgical site, which is configured to receive a fastener to fix the spinal plate to the spine.

Abstract: An implant assembly including an expandable vertebral body replacement implant. The implant assembly includes a right hand end and a left hand end configured to attach to a threaded actuator. An outer ring is configured to surround each of the right and left hand ends and the threaded actuator. The implant assembly may include removable endplates configured to engage vertebral bodies as interbody spacer or through a corpectomy. The implant assembly includes a locking mechanism to prevent collapse or movement the implant assembly after implantation. The locking mechanism automatically engage after removal of an inserter instrument from the implant assembly.

Abstract: Expandable fusion devices, systems, and methods thereof. The expandable fusion implant may include upper and lower endplates configured to engage adjacent vertebrae and an actuator assembly for expanding the upper and lower endplates to independently control anterior and posterior heights of the implant. The actuator assembly may be operated in two modes: (1) to force the upper and lower endplates apart resulting in parallel expansion; and (2) to increase the anterior height of the implant resulting in an increase in lordotic angle.
