A bioactive spinal implant used in cervical fusion, Anterior Lumbar Interbody Fusion (ALIF), Posterior Lumbar Interbody Fusion (PLIF), and Transforaminal Interbody Fusion (TLIF), having properties and geometries that enhance bone contact, stability, and fusion between adjacent vertebral bodies.

An improved anterior cervical plating system and methods of cervical fusion using such a system are provided. The cervical plating system includes an interlocking mechanism that integrated into each of the plates such that any two plates may cooperatively engage through the interlocking mechanism such that a new cervical plate can be interconnected with a pre-existing plate during revision surgery without removal of the pre-existing plate.

A surgical screw that includes a body portion that facilitates bone in-growth from a bone in which the screw is mounted so as to stabilize the screw in the bone. The body portion can have various configurations for facilitating bone in-growth, such as indentations, a roughened surface, such as by acid etching or abrasive media blasting, specialized coatings, such as hydroxyapetite, sintered beads, machined channels, etc. Because the body portion of the screw facilitates bone growth, the screw will be more firmly mounted to the bone so as to have a greater integrity in response to movement of the bone. The type of surgical screw can be any surgical screw that will benefit from being better anchored in bone, such as pedicle screws, long bone screws, cervical fusion screws, tendon anchoring screws, etc.

A posterior cervical fusion surgery assembly and method. The assembly includes a sled adapted to be positioned in a facet joint and two receivers slidably mounted on the sled. The receivers are adapted to support surgical instruments such as a drill, a tap, and a screw. The sled assists in orienting the instruments at a desired angle with respect to the spine.

In an exemplary embodiment of the present invention, a method of implanting a fusion plate, having at least two primary fastener openings, into a patient is described. According to the inventive method, a throat of the patient is dissected, providing access through the throat dissection to a spinal column of the patient. The fusion plate is inserted into the throat dissection, and the fusion plate is then positioned in an asymmetrical relationship with a sagittal plane of the spinal column. A first primary fastener is inserted through a first primary fastener opening of the fusion plate and into the first vertebra. A second primary fastener is inserted through a second primary fastener opening of the fusion plate and into the second vertebra. A cervical fusion apparatus is also disclosed.

The invention discloses an adaptive floating combined cervical interbody fusion cage comprising a cage body, a steel plate, a screw and a spherical connection mechanism. The screw penetrates the steel plate and the spherical connection mechanism to fix to the cage body, and the steel plate is rotationally connected to the fixed end of the cage body through the spherical connection mechanism. The steel plate and the cage body are connected in a floating manner, the fusion cage can be adjusted according to the implant position, the adjacent cervical surfaces are fitted tightly, the screw between the steel plate and the cage body is screwed after the adjustment to fix the steel plate and the cage body, the incision is small, and the operation difficulty is low.

The invention discloses an occipital bone fixation assembly for occipital-cervical fusion, which comprises a screw part, a fixing plug and a tightening nut; a clamping part is arranged at the bottom of the screw part, and the clamping part is connected with the screw part, and the bone is punched at the thicker part of the occipital bone. hole, so that the clamping part passes through the bone hole and cooperates with the fixed plug and the tightening nut to make a fixed connection with the occipital bone; the fixed plug includes a plug hole, an upper disc cap and a lower plug tube; the upper disc cap and the lower plug tube are integrally formed, and the The centerlines of the upper disc cap and the lower plug tube are collinear, the plug hole runs through the upper disc cap and the lower plug tube, the lower plug tube is a hollow tube, which can be used for bone grafting, and the side wall of the tube is distributed with circular holes Facilitate the fusion of bone graft and occipital bone hole; because the bottom clamping part of the screw rod is in contact with the inner plate of the occipital bone, the lower surface of the tightening nut is in contact with the upper disc cap, and as the tightening nut is tightened, the lower surface of the upper disc cap is in contact with the occipital bone The outer plates are in contact with each other, and as a whole, the screw part is tightly fixed on the occipital bone to achieve the purpose of fixing. Since the connection method of this method is clamped and fixed up and down, the force volume of the fixed component and the occipital bone is larger.

A Cloward-style cage device for anterior cervical fusion and fixation includes a body and a lateral stabilizer. The device uses the historical Cloward-style approach, and, as such, decompresses the interbody disc. The device can be used with a cylindrical drill bit to drill through the interbody disc to remove a portion of the interbody endplates to decompress a remaining portion of the interbody disc. The lateral portions of the endplates are generally preserved. The device has a cylindrical body formed of a mesh-like material, with lateral stabilizers.
