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 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 fixation system for repairing a pars fracture includes a needle guide configured to be docked on a lamina of the pars, a needle, a guidewire, and a screw assembly. A portion of the needle is configured for insertion through a passage of the needle guide. A portion of the guidewire is configured for insertion through a passage of the needle. The screw assembly includes a collar and an elongated portion, the collar being movable with respect to the elongated portion. A portion of the screw assembly is configured to contact the lamina co-axially with the guidewire.

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.

An adjustable spinal stabilization system for maintaining preselected spacing and movement between adjacent vertebrae in a spinal column and for providing overall stability thereto. The system includes at least one interlaminar member positioned in the spaces intermediate a first vertebra and the vertebrae positioned immediately above or immediately below and adjacent to the first vertebra. The interlaminar member is operatively connected to an adjustable support structure and cooperates therewith to maintain the preselected spacing between adjacent vertebrae and to provide overall stability to the spinal column.

Various embodiments of a spinal shield having a shield body including a plurality of lateral extensions configured to be positioned over an exposed spinal canal for establishing a protective barrier around the contents of the exposed spinal canal are disclosed.

For treating a fracture in a pars interarticularis, methods and apparatus provide for: (i) coupling a spinous process plate to a lateral side of a spinous process of a spine of a patient, the spinous process plate extending substantially parallel to a sagittal plane through the spine, the spinous process plate including a first fixation element configured to attach the spinous process plate to the lateral side; (ii) coupling a laminar plate to a laminar on the lateral side, the laminar plate extending transversely from the spinous process plate and transversely to both the sagittal plane and a coronal plane through the spine, the laminar plate including a second fixation element configured to attach the laminar plate to the laminar on the lateral side; (iii) engaging a sub-laminar hook to the laminar on the lateral side, the sub-laminar hook extending transversely from the laminar plate and substantially parallel to a transverse plane through the spine, the sub-laminar hook configured to extend and hook beneath the laminar on the lateral side; (iv) extending a rod toward a pedicle on the lateral side, the rod having proximal and distal ends and extending substantially perpendicular to a length of the fracture, from the laminar plate toward the pedicle; and (v) anchoring the rod in a configuration that prohibits movement of first and second parts of the fractured pars interarticularis relative to one another, by coupling the proximal end to the laminar plate, and the distal end to the pedicle on the lateral side.

A spinal implant includes a first member configured to penetrate tissue and a second member. The second member has an abutment engageable with a surgical instrument and at least one peripheral capture element engageable with a moveable arm of the surgical instrument. Systems, spinal constructs, surgical instruments and methods are disclosed.

A device for reconstructing a spinous process, the device comprising a main portion having at least a first engaging hole; one fixing bar transversely insertable into the engaging hole; and said main portion having at least one through-seat for inserting ligaments to be reconstructed. Other aspects are disclosed and claimed.

A surgical implant device configured to adjust in planar orientation or angular orientation or both to correspond to the structure of the lamina to be spanned at the site of a cut of the laminoplasty surgery. The device includes a base having slots extending adjacent thereto, and an extension having a head configured to be adjustably positionable within the slots.
