A spinal stabilization system may include at least one pedicle screw comprising a threaded base to be connected to a superior pedicle of a vertebra and a screw head attached to the threaded base. The system may further include at least one pars interarticularis clamp comprising an elongate body defining a screw head connection point to be connected to the screw head of the pedicle screw, and a laminar hook coupled to the elongate body and configured to wrap around an edge of the lamina and compress the pars interarticularis of the vertebra when the screw head connection point is connected to the screw head.

A translaminar pedicle anchor suspension system (referred as T-PAS system) applicable to vertebral surgeries is disclosed. The T-PAS system comprises: at least one pedicle anchor capable of being fixed to a pedicle of a lower vertebral segment, at least one suspension ligament having one end thereof fixed to the pedicle anchor, and at least one washer capable of fixing the other end of the suspension ligament to a contralateral side of a lamina of an upper vertebral segment. By using the suspension ligament to suspend the upper vertebral segment via a tunnel drilled on the lamina, not only the spine can be dynamically stabilized, but also the use of traditional pedicle screws and bone fusion can be avoided.

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.

Dural repair devices that are configured to effectively and reliably repair the damage of a dural tear due to incidental durotomies are provided, along with methods of use. The devices and methods enhance the ability of a surgeon to repair a patent's dura mater, or dura, during surgery of the central nervous system. The dural repair device has a multi-layer structure configured to exert a pressure or tamponade effect to compress a patient's dura to its state prior to the spinal surgery. Thus, the dural repair devices and methods of use may reduce the patient's risk morbidity, further surgery, spinal headaches, or other injuries and discomforts.

Systems, methods, and devices for securing a sublaminar band are provided. A sublaminar band clamp system may include a first locking mechanism, a second locking mechanism, and a body. The body may include a first portion comprising a first passage, wherein the first locking mechanism is disposed within the first passage. The body may further include a second portion comprising a second passage, wherein the second locking mechanism is disposed within the second passage. A third passage may extend across the body and may be in fluid communication with the second passage. An opening may be positioned between the first and second portions, and the opening may be in fluid communication with the first passage.

Methods and apparatus for accessing and repairing a vertebral disc include a pad with a central cut-out mounted to the skin of a patient or, alternatively, a pedicle-mounted support. An incision is made and then a corridor is created using an elongated guide and a series of dilating tubes. An access to the disc space is created through the superior articular process and the facet joint using the corridor defined by the dilating tubes. Nucleus material is removed from the disc space and the vertebral endplates are prepared. The disc space may be sized to select a suitable implant, which is advanced through the corridor and into the disc space following discectomy and endplate preparation. Bone graft material may be inserted into the disc space following installation of the implant and then posterior rigid fixation may be achieved using percutaneous pedicle screws, followed by closure of the site.

Disclosed are laminoplasty devices and systems, kits that include such laminoplasty devices or systems or components thereof; and methods of assembling and using such laminoplasty devices and systems. In particular, articulating laminoplasty devices are provided that allow lamina plates to be adjusted angularly and transitionally with respect to a cage connecting the lamina plates. Also provided are laminoplasty plates that are configured so as to be assembled with a bone graft housing, and which provide an opening configured to facilitate bone graft insertion into the housing. Further provided are expandable laminoplasty fixation systems that include a lateral mass plate, a lamina plate and a set screw that when screwed and unscrewed, allows one to contract and expand the plates with respect to one another.

Methods and apparatus provide for coupling a spinous process plate to one lateral side of a spinous process of a spine of a patient; coupling a laminar plate to a laminar on the one lateral side of the spinous process of the spine; engaging a sub-laminar hook to the laminar on the one lateral side of the spinous process; and (iv) extending a rod toward a pedicle on the one lateral side of the spinous process of the spine of the patient, where the rod prohibits movement of bone associated with a fracture in a pars interarticularis of a vertebral arch on the one lateral side of the spinous process of the spine.

A single device desirably configured for use at complete cut location of an open door laminoplasty surgical site, and to be adjustable in size and orientation so that they may be adapted to the site at the time of surgery. The device is a one-piece construct of a base with an integrated spacer, with an extension hingedly connected to the base. The base and spacer are integrally formed of material that is not bone or bone-like, such as titanium. The spacer is devoid of void or open areas and includes arched proximal ends.

A surgical system includes a trial connected with a first image guide oriented relative to a sensor to communicate a signal representative of the trial relative to a patient anatomy. A tracking device includes the sensor and communicates with a processor to generate a storable image of the trial relative to the patient anatomy for display from a monitor. A spinal implant is connected with a second image guide oriented relative to the sensor to communicate a signal representative of the spinal implant relative to the patient anatomy. The sensor receives the signal of the second image guide and communicates with the processor to generate an image of the spinal implant in real time for display from the monitor in a configuration to align the spinal implant in real time with the stored image of the trial. In some embodiments, methods, spinal constructs, implants and surgical instruments are disclosed.
