A method for performing a surgical procedure on a patient using a robotic system and a navigation system. The robotic system includes a cutting tool. The navigation system has at least one locating device to track a portion of the patient during the surgical procedure. The navigation system provides information as to a position of the portion of the patient. An optical cutting guide is projected onto the portion of the patient to enable cutting of the portion of the patient with the cutting tool of the robotic system while the optical cutting guide is projected onto the portion of the patient.

An expandable implant having superior and inferior endplates is disclosed. The superior endplate includes a first inside surface having a crossbar extending in the widthwise direction. The inferior endplate includes a second inside surface having a medial support structure, a threaded core, and a receiving cavity. A threaded locking screw may be disposed in the threaded core, and a proximal saddle may be disposed in the receiving cavity. In various embodiments, in a locked position, a relative position of the inferior endplate with respect to the superior endplate is fixed, and the threaded locking screw directly contacts, pushes, applies a force against, and/or compresses, the proximal saddle, the proximal saddle directly contacts, pushes, applies a force against, and/or compresses the crossbar, the crossbar directly contacts, pushes, applies a force against, and/or compresses the distal saddle, and the distal saddle directly contacts and is engaged against the second interior distal wall.

Exemplary assemblies, apparatuses, systems, methods, and kits are provided herein related to modular tibial inserts. One such assembly can comprise a modular tibial insert assembly having: a modular medial insert component, the modular medial insert component having a medial component proximal side proximally disposed from a medial component distal base side, wherein a medial component body extends between the medial component proximal side and the medial component distal base side; a modular lateral insert component, the modular lateral insert component having a lateral component proximal side proximally disposed from a lateral component distal base side, wherein a lateral component body extends between the lateral component proximal side and the lateral component distal base side; wherein the modular tibial insert assembly has an assembled configuration and a disassembled configuration, and wherein the modular medial insert component is configured to fixedly engage the modular lateral insert component in the assembled configuration.

Provided is a structurally stable interbody cage. An interbody cage 1 includes a main body 2 distally including two branches 20,21 that are spaced apart from each other upward and downward, a rod 3 provided in the main body 2 so as to extend between the two branches 20,21, and a slider 4 configured to separate the two branches 20,21 upward and downward, the slider 4 being supported by the rod 3 so as to be movable in an axis direction of the rod, wherein the two branches 20,21 each distally have an inclined surface 26A, the inclined surfaces 26A facing each other, the distance between the inclined surfaces 26A gradually increasing toward distal ends thereof; the slider 4 slides on the inclined surfaces 26A of the two branches 20,21 when the slider 4 moves in the axis direction of the rod 3, and the two branches 20,21 each proximally have a constricted part 27 with a narrow thickness and an opening 5 is present between the upper constricted part 27 and the lower constricted part 27, the opening 5 being formed by a plurality of holes 50 to 52 continuous in the axis direction of the rod 3 and having an upper edge and lower edge that form protruding curves in a lateral view.

A vertebral implant device is described comprising a wedge, a plate having an external surface configuration and one or more plate tine, a staple having one or more staple tine and a coupling device. The coupling devices is configured to couple the wedge, the plate and the staple whereby when the vertebral implant is secured in a vertebral body, the external surface configuration of the plate alters the relative orientation of a superior endplate surface plane and an inferior endplate surface plane of the vertebral body and alters the alignment of the spine. In some embodiments, plate tines and staple tine are configured to frictionally engage the vertebral body. In some embodiments, the coupling device is a screw and a nut. In some embodiments, interchangeable wedges are used to provide multiple implant device configurations.

Systems for joint arthroplasty include prostheses which are secured to bone with sliding anchors. Examples include unicondylar and bicondylar knee prostheses for hemi-arthroplasty and total arthroplasty. Instruments guide the anchors into proper engagement with the prosthetic components. Methods of using the prostheses and instruments are disclosed.

A bone graft delivery system and method for using same to deliver graft material into a surgical site. The system includes an interbody implant having a securing site disposed on a surface of the implant and a holder having an elongated, hollow handle including a distal end. The distal end of the holder is configured to removably engage the securing site of the interbody implant to secure the interbody implant to the distal end of the holder until such time as a user desires to disengage the holder from the interbody implant. The interbody implant may be a cage implant having opposing anterior and posterior surfaces, opposing first and second lateral surfaces, and opposing top and bottom surfaces, wherein the top surface comprises a first aperture and the bottom surface comprises a second aperture, the posterior surface comprising a third aperture, the first, second, and third apertures all linking to a main cavity, the main cavity generally extending between the top surface and the bottom surface.

Expandable fusion devices, systems, instruments, and methods thereof. The expandable fusion device is capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. The fusion device may include a body, a first endplate, and a second endplate. A drive screw may be rotated to move the first and second endplates outwardly and into an expanded configuration. Instruments may be provided to ensure the implant is inserted safely and as intended.
