The present invention relates to prostheses for treating spinal pathologies, and more specifically to a system and method for treating articulating surfaces of cervical vertebrae facet joints. The system includes a superior implant for placement on a superior articulating surface and an inferior implant for placement on an inferior articulating surface. In addition, described is a method for providing articulating surfaces for cervical vertebrae facet joint articular facets.

Systems and method in accordance with the embodiments of the present invention can include an implant for positioning within a cervical facet joint for distracting the cervical spine, thereby increasing the area of the canals and openings through which the spinal cord and nerves must pass, and decreasing pressure on the spinal cord and/or nerve roots. The implant can be inserted laterally or posteriorly.

Prostheses and methods for repair of cervical fact joints. In one aspect, the articulating surfaces of the natural facets of a facet joint are removed only a sufficient amount to allow the insertion of flat or slightly curvilinear portions of prostheses therebetween in an overlapping relationship. The portions are so inserted and the prostheses mounted by attachment to adjacent vertebrae. Also, a single natural facet may be similarly repaired with a single prosthesis. In another aspect, the invention provides a single prosthesis that is useful in repairing articulating surfaces in more than one cervical facet joint.

In an embodiment of the present invention, a tool resembles an implant for positioning within a cervical facet joint. The tool can be used for distracting and/or sizing the cervical facet joint and thereby distracting the cervical spine and increasing the area of the canals and openings through which the spinal cord and nerves must pass, and decreasing pressure on the spinal cord and/or nerve roots. The tool can be inserted laterally or posteriorly.

A device and method for a minimally invasive surgical implantation to reduce radicular symptoms by inserting an expandable cervical distraction implant in the facet joint and distracting the adjacent cervical vertebrae to increase the foraminal dimension. The implant, when positioned in the cervical facet joint, expands to via delivery of an inflation medium to increase the space between the vertebrae, thereby increasing the foraminal area or dimension, and reducing pressure on the nerves and blood vessels of the cervical spine.

A spinal fixation access and delivery system is disclosed. In some aspects, the system is used to access the cervical facet joint via a posterior access approach. The system may include an access device including a body having a proximal portion and a distal portion and a chamfered or beveled end feature positioned at the distal portion of the body and configured for insertion at the cervical facet joint. The system may further include a guide device having access device engagement features and a spinal fixation member. The access device includes at least one guide device receiving feature complementary to or keyed to the engagement feature of the guide device.

The invention discloses an anterior cervical facet joint twist lock distraction reduction device. The anterior cervical facet joint twist lock distraction reduction device comprises a restoration assembly and a locking assembly. The restoration assembly comprises handheld parts, the middles of the two handheld parts are hinged, first adjusting cylinders are arranged at the bottom ends of the handheld parts and rotationally connected with the handheld parts, the first adjusting cylinders sleeve the peripheries of the tops of distraction rods, the bottom ends of the distraction rods are fixedlyconnected with intervertebral distraction plates, the bottoms of the distraction rods penetrate through a vertebral body front edge pressing plate, and the distraction rods are in threaded connectionwith the vertebral body front edge pressing plate; and the locking assembly comprises an anterior steel plate and an intervertebral space steel plate, and the anterior steel plate comprises a head steel plate, a telescopic sleeve rod and a tail steel plate which are fixedly connected in sequence in the length direction. The two processes of distraction and lifting a vertebral body are combined inone device, the operation is easy, and meanwhile the anterior fixation is more flexible.

The invention relates to a cervical facet joint dislocation massage instrument. In order to solve the problem that because the current product is wrapped around the neck, in order to realize the up and down pulling of a distance of each joint of the cervical spine, and restore each joint to a correct position, the mandible must be moved up and down together, but an up and down movement range of the flexible mandible is relatively large after bearing a force, it is difficult to coordinate with each joint of the cervical spine, and thereby satisfactory treatment effects cannot be achieved, the cervical facet joint dislocation massage instrument is proposed. The massage instrument comprises a head support frame, a neck bracket, a telescopic support frame, adjustment support frames, and massage mechanisms. The design has simple making process and low cost, the making cost is saved while making more people affordable, an interval between the head support frame and the neck bracket can be adjusted to adapt to people with different neck lengths and thicknesses, the tail of the neck support frame, namely the neck end, is provided with the adjustment support frames, the ergonomics is easierto fit, a neck position fixing apparatus is abutted against to ensure that the apparatus cannot fall off, the massage mechanisms follow the trend of manual massage, it is more in line with the traditional Chinese medicine skill, and the effect is better.
