The present invention discloses an interspinous process fusion device, a method of fabricating the interspinous process fusion device, and a surgical method for maintaining a space between two spinous processes in a spine of a patient using the fusion device. The interspinous process fusion device including a distal tip member, a middle plate, a proximal plate, an elongate member, and a plurality of movable wings. The elongate member having a first end, a second end, and a longitudinal axis extending between the first and second end. The distal tip member is connected to the first end of the elongate member, the proximal plate is connected to the second end of the elongate member, and the middle plate and plurality of wings are positioned intermediate the distal tip member and the proximal plate along the longitudinal axis to form the interspinous process fusion device assembly.

A total artificial spinous process (spino)-laminar prosthesis (TASP-LP) including a body having a portion forming a spinous process extending away from the body, a first lamina portion extending from a first side of the body, and a second lamina portion extending from a second side of the body, wherein the first lamina portion and the second lamina portion are disposed on opposite sides of the spinous process.

A system includes a first pedicle screw, a second pedicle screw, and an adjustable rod having an outer housing coupled to one of the first pedicle screw and the second pedicle screw, the outer housing having a threaded shaft secured to one end thereof extending along an interior portion thereof. The system further includes a hollow magnetic assembly disposed within the outer housing and having a magnetic element disposed therein, the hollow magnetic assembly having an internal threaded surface engaged with the threaded shaft, the magnetic assembly being coupled to the other of the first pedicle screw and the second pedicle screw, wherein the hollow magnetic assembly rotates in response to an externally applied magnetic field to thereby lengthen or shorten the distance between the first pedicle screw and the second pedicle screw.

An implant system for correcting deformities is provided. The implant system includes A proximal extension having a hollow interior and a distal extension configured to be received within the hollow interior of the proximal extension. The implant system also includes a locking element configured to lock the distal extension from moving with respect to the proximal extension. The distal extension is configured with ratchet teeth on a top surface for interacting with a distractor instrument for contacting or distracting the distal extension with respect to the proximal extension. The proximal extension and distal extension are configured to receive clamping elements for coupling to the implant to anatomical regions of the body.

Lamina plates can include various features that allow a surgeon to couple the plate to a vertebra, such as a plurality of receiving holes for receiving a spinal fixation element. The plate can be shaped and the receiving holes positioned such that spinal fixation elements can be installed with reduced exposure of the spine and along a trajectory that enhances purchase with bone. The lamina plate can include one or more features for coupling at least one receiver head to the plate for receiving a spinal stabilization element. Since the receiver head can be coupled to the plate after the plate is implanted, it does not restrict the range of angles or trajectories at which the spinal fixation elements can be installed.

A method of repairing a pars fracture includes docking a needle guide on a lamina of the pars, inserting a needle at least partially through the needle guide, inserting a stylet at least partially through the needle, inserting a guidewire at least partially through the needle, removing the needle from the needle guide, removing the needle guide, positioning a screw assembly in contact with the lamina and co-axially with the guidewire, rotating an elongated portion of the screw assembly with respect to the lamina to move the screw assembly distally with respect to the lamina such that a distal end of the elongated portion of the screw assembly travels through an interior portion of the pars and into a superior portion of the pars, and approximating the distal end of the elongated portion of the screw assembly and a collar of the screw assembly to approximate the interior portion of the pars and the superior portion of the pars.

Lamina plate assemblies, systems, and methods thereof. A lamina plate assembly may be configured to provide lamina support following laminectomy, for example, in cervical and lumbar cases. The lamina plate assembly may include a generally elongate body having a first free end, a second free end, and a posterior portion disposed between the first free end and the second free end. Different embodiments of securing portions are used to secure the lamina plate assembly to a vertebra.

The invention discloses a bionic artificial spinal joint, wherein the spinal joint includes a plurality of fixing units, the fixing units are fixed on a vertebral body, at least two fixing units located on one side of a spine are arranged along the extension direction of the spine and fixed in sequence, and sufficient force can be borne between two adjacent fixing units. The overall micro-motion joint structure formed by two adjacent fixing units is both supportable and bendable. The present application imitates the function of the human inter-process joints, so that the spine equipped with the bionic artificial spine joint can be bent within a certain angle range while maintaining the height of the intervertebral space, thereby avoiding the problem of spinal rigidity after the traditional spine surgery pedicle internal fixation.

Various embodiments described herein provide devices and associated methods for treating spinal disease by implanting one or more interspinous process spacing devices. In one embodiment, an interspinous process spacing device includes a first attachment side, a second attachment side, a spacer tray, and a securing means. The spacer tray extends from the first attachment side and is slideably insertable through a spacer tray slot formed in the second attachment side. The spacer tray is adapted to be positioned between a spinous process of a first vertebra and a spinous process of an adjacent second vertebra, and the spacer tray includes a trough formed in a top surface of the spacer tray. The securing means is configured to engage the trough of the spacer tray to secure the second attachment side relative to the first attachment side.

Interspinous process implants are disclosed. Also disclosed are systems and kits including such implants, methods of inserting such implants, and methods of alleviating pain or discomfort associated with the spinal column.
