Abstract: The implant includes two side walls resting against the vertebral end-plates and an intermediate wall joining the supporting walls. The implant can be deformed for insertion between the vertebrae to be treated to restore the attenuated mobility of the vertebrae, and includes mounting elements mounting on the vertebrae. The side walls have a curved shape, whose convexity is oriented towards the outside of the implant; the intermediate wall has a curved shape, whose convexity is oriented towards the outside of the implant such that it does not form any pronounced angles with the supporting side walls. The supporting side walls and the intermediate wall, have a partially oval shape; and the mounting elements are configured such that the implant can be mounted on the vertebrae.

Abstract: A bone fastener assembly instrument that can assemble a two-component bone fastener during surgery is provided. The bone fastener may be of a type that comprises a threaded bolt and nut for securing an implantable device to bone, such as a spinous process. A method for using the bone fastener assembly instrument is also provided.

Abstract: The present invention provides interspinous vertebral and lumbosacral stabilization devices, and methods of using these devices for treating spinal instability conditions. The invention includes interspinous vertebral stabilization devices adapted for placement between the spinous processes of two or more adjacent vertebrae. The invention also includes lumbar stabilization devices adapted to be placed between a lumbar vertebra and an adjacent vertebra, including the first sacral vertebra (S1), to stabilize the lumbosacral region of a patient, and method for using such devices.

Abstract: A functionally dynamic stabilization unit and system for treatment of spinal instability are provided. Each unit, and collectively, the system, is configured to control flexion, extension and translation of the affected unstable vertebral area, thereby stabilizing the vertebral segments by restoring normal function. This is achieved by providing a unit and system that allow for lateral bending, axial compression, rotation, anterior segmental height adjustment, and posterior segmental height adjustment. The unit and system provide sufficient segmental stiffness, while also limiting, or controlling, the range of motion (i.e., sufficient stiffness in the neutral or active zone, while limiting or preventing motion outside of the active zone) to stabilize the vertebral segments. In use, the system mimics the natural movement of the normal spine. Furthermore, the system includes a rigid, fusion-promoting coupler configured for use in an adjacent level, or as a substitute for the functionally dynamic unit.

Abstract: A modular, customizable system that provides components for assembling an implantable device is provided. The system allows the user to assemble an implantable spine stabilization device that is flexible and allows dynamic stabilization. The same system also provides components for assembling a rigid or non-flexible fusion-enabling spine stabilization device. The components of the system are easily interchangeable, allowing the user the ability to customize the assembled device for a true fit with the patient, as well as allow an easy conversion of the dynamic device into a fusion-enabling device. Associated insertion instruments and methods of use are also disclosed.

Abstract: A surgical instrument system comprises surgical instruments for use with an implantable interspinous device having at least one pair of wings for securing the implantable device to a spinous process. The instrument system may include a surgical instrument for expanding or spreading the pair of wings to accommodate the spinous process. Further, a surgical instrument may be provided for crimping or compressing the pair of wings against the spinous process for secure attachment of the device to a vertebra. The surgical instruments may be configured similar to pliers and apply force to the pair of wings within a predetermined range so as to avoid damage, weakening or breakage of the pair of wings. The surgical instrument system may also include interspinous devices of differing sizes.

Abstract: A bone-anchoring device is provided. The bone-anchoring device may comprise a screw including a threaded shaft portion configured to engage bone tissue, and a head portion having a cup-shaped cavity. The device may further include a rod connector and a linking member, wherein the linking member includes a spherical head portion configured to engage the cup-shaped cavity of the head of the screw, a widened flange s configured to engage the linking member, and an elongate body extending from the widened flange portion and configured to extend through an opening in the rod connector.

Abstract: Implantable devices are provided for stabilizing adjacent vertebrae and the lumbosacral region of a patient. The devices can comprise an interspinous flexible spacer body having a substantially U-shape comprising a superior section, inferior section, and a midsection extending therebetween. The superior and/or inferior sections can include a pair of lateral walls configured to engage a spinous process of a vertebra. Fixation caps can be provided for securing a spinous process of a vertebra to the flexible spacer body. To secure the flexible spacer body between the lumbar vertebra and an adjacent vertebra, an anchor assembly is provided. Also provided are methods of using the implantable devices to stabilize a patient's spine.

Abstract: An implantable interlaminar-interspinous stabilization system is provided. The system may comprise a U-shaped implantable device having an inferior section, a superior section, a midsection extending therebetween, and pair of lateral walls for engaging a spinous process of a vertebra, each of the lateral walls including an aperture with a countersink for receiving a bone fastener. The system may also include a bone fastener comprising a threaded bolt and a threaded nut for securing the implantable device to the spinous processes. Insertion tools may be provided for aligning the threaded bolt and nut through the apertures of the implantable device.
