The expandable fusion implant may include an upper endplate and a lower endplate configured to engage adjacent vertebrae, an actuation gear configured to adjust a height of the upper endplate, an interface collar configured to attach to an inserter instrument at multiple orientations for a desired surgical approach, and an expansion and orientation lock configured to lock the orientation of the interface collar and lock the height of the upper endplate. The expandable fusion device is attachable to the inserter instrument to secure the interface collar and disengage the lock from the actuation gear to permit expansion of the upper endplate.

Abstract: Embodiments herein are generally directed to vertebral implants and implant trials for use with vertebral implant assemblies. In some embodiments, these implants and implant trials may be used in conjunction with corpectomy procedures.

Abstract: A bone stabilizing plate includes two plate portions, each affixable to bones of a patient, the plate portions telescoping together with mating rails and grooves. A limiter associated with one of the plate portions sliding engages one a catch associated with the other of the plate portions, when the plate portions are telescoped together, and resists stops telescoping when the plate portions are telescoped a predetermined distance apart. Once the limiter and catch are engaged, the plate portions enable imposition of a minimum compressive force between bones connected to the plates. The limiter is resiliently positioned to deflect into a relief formed in its respective plate portion. A groove positioned proximate the catch enables free telescoping motion limited by the engagement of the catch and limiter, whereby the minimum compressive force between bones is maintained, and Wolfe's Law may apply.

Abstract: A surgical driver apparatus includes a housing and an inner driver shaft having a proximal end secured within the housing and a distal end extending out from a first side of the housing. The inner driver shaft is configured to rotate with respect to the housing. The surgical driver apparatus further includes an outer driver shaft and an idler driver shaft. The outer driver shaft is positioned coaxial with the inner driver shaft and configured to rotate independently from the inner driver shaft. The idler driver shaft is configured to transmit torque to the outer driver shaft. Additionally, the surgical driver apparatus includes a driver key comprising a driving feature and a counter-driving feature. The driver key is configured to engage a second side of the housing in one of a plurality of orientations configured to rotate the inner driver shaft and/or the outer driver shaft.

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: 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.

Abstract: An inserter assembly for a spinal plate which includes a fastener hole for receiving a bone screw. The assembly includes an awl, and a shaft having a lumen for receiving the awl and a distal tip. A collar has a central hole for receiving the awl. A distal collar tip is adapted to be inserted into the fastener hole. An interior curved surface of the collar receives the distal tip of the shaft for polyaxial movement of the shaft relative to the collar.
