A device for treatment of spondylotic disease includes a distractor for distracting vertebral facets of first and second vertebrae located adjacent each other. The distractor includes a first abutment surface for interfacing with an inferior articular facet of the first vertebra. The distractor also includes a second abutment surface for interfacing with the superior articular facet of the second vertebra corresponding to the inferior articular facet of the first vertebra. The first and second abutment surfaces of the distractor engage with each other and are separated by a predetermined distance.

The present application generally relates to orthopedic systems, and in particular, to systems including independent plates and spacers. A plating system can include a spacer and a plate that is independent from the spacer. A number of locking mechanisms can be provided to secure the plate to the spacer. In some cases, the spacer includes a pair of notches that extend on an outer surface of the spacer. The plate can include a pair of lateral extensions that can engage the notches to secure the plate to the spacer. In other cases, the spacer includes an opening including a pair of inlets. The plate can include an enclosed posterior extension that can be received in the pair of inlets to secure the plate to the spacer.

A vertebral facet distractor includes an elongated generally cylindrical contour including a first end surface, a second end surface, an outer sidewall, an inner sidewall, and a central lumen having an opening in one of the first end surface and the second end surface. The outer sidewall may be provided with a surface irregularity, such as a screw thread. The vertebral facet distractor may further include a holder including an elongated body and a tip that extends through the opening and is engaged with the contour. The tip may be provided with a screw thread that is engaged with the contour or may engage the contour in an interference fit.

Instruments, kits, and methods are disclosed for installing an implant spacer through an incision and down a surgical corridor. The instruments also serve to align a drill guide and align and insert a spacer stabilizer for stabilization of adjacent bone portions. The instrument comprises an elongated guide bar body, an inserter face at a distal end of said guide bar body for abutting an instrument attachment portion of a spacer, a connection tip portion for securing a spacer against an inserter face, and a guide portion of said elongated guide bar body for aligning instruments with said spacer and for introducing a stabilizer to secure the spacer in a predetermined position between the bone portions. Included is a retractable graft block for securing graft material within an aperture of said spacer during insertion of the spacer.

The present disclosure relates to an implant for insertion into an intervertebral space between a first vertebral member and a second vertebral member subsequent to a removal of a third vertebral member between the first vertebral member and the second vertebral member, the implant includes a first end, a second end and an implant body. The first end is to be secured to the first vertebral member. The second end is to be secured to the second vertebral member. The implant body is between the first end and the second end, wherein the implant body provides relative motion between the first end and second end.

An intervertebral cage structure that comprises a main body having a first surface and a second surface located opposite to the first surface, a first plate disposed on the first surface of the main body, a second plate disposed on the second surface of the main body, and an opening formed at a center portion of the intervertebral cage structure and extending from the first plate to the second plate via the main body, wherein the first and second plates comprise a surface pattern comprising at least one of a symmetrical geometric pattern and an asymmetrical geometric pattern.

A vertebral facet distractor intended to be positioned between first and second articular facets in an articular facet joint to provide distraction between the first and second articular facets includes an elongated generally cylindrical contour including opposed top and bottom surfaces, an outer sidewall, an inner sidewall, and a central lumen that defines an opening in the bottom surface. The outer sidewall is provided with a surface irregularity to promote bone fusion when the vertebral facet distractor is positioned between the first and second articular facets in the articular facet joint.

An implant for use in spinal surgery comprises a resilient element having an inflatable cavity. It is formed of a biologically compatible material and is arranged for placement between end plates of adjacent vertebra. The implant may also include a wound disc replacement element. A method of performing spinal surgery on a patient comprises securely mounting a patient onto a patient support table; imaging a spinal region of the patient; building up a three-dimensional image file of the spinal region of the patient; storing the image file; and utilizing the image file for planning and carrying out computer controlled spinal surgery on the patient utilizing the implant. A computer-controlled surgical implant system comprises a steerable endosurgical implanting assembly operative to install the implant at a desired location in a patient; and a computerized controlled, which operates the steerable endosurgical implanting assembly.

A method of performing a computer-assisted surgical procedure on the spine of a patient comprising the steps of: planning, on a computer, a surgical procedure based on at least one of two- and three-dimensional images of the patient's spine; affixing a robotic assembly over an operative region of the patient; determining, with a computer in communication with the robotic assembly, a desired trajectory of a surgical tool along at least one of an access path and an implant path towards the surgical target site; and placing at least a portion of the surgical tool through the aperture along said desired trajectory along at least one of said access path and said implant path towards the surgical target site.
