20090105757 | Posterior stabilization systems with shared, dual dampener systems - Dynamic posterior stabilization systems and methods of stabilizing vertebrae are described. A dynamic posterior stabilization system may include a first bone fastener configured to couple to a first vertebra, a second bone fastener configured to couple to a second vertebra, and a dampener system attached to the first bone fastener and the second bone fastener. The dampener system may include a first dampener set and a second dampener set. Compression of the first dampener set provides resistance to movement of the first bone fastener towards the second bone fastener. Compression of the first dampener set and the second dampener set provides resistance to movement of the first bone fastener away from the second bone fastener. | 04-23-2009 |
20090105758 | Dampener system for a posterior stabilization system with a variable length elongated member - Dynamic posterior stabilization systems and methods of stabilizing vertebrae are described. A dynamic posterior stabilization system may include a first bone fastener configured to couple to a first vertebra, a second bone fastener configured to couple to a second vertebra, and a dampener system attached to the first bone fastener and the second bone fastener. The dampener system may include a single dampener set. Compression of the single dampener set provides resistance to movement of the first bone fastener towards the second bone fastener. Compression of the first dampener set and the second dampener set provides resistance to movement of the first bone fastener away from the second bone fastener. | 04-23-2009 |
20090105759 | Spinal stabilization systems with dynamic interbody devices - A stabilization system for a human spine is provided. The stabilization system may include one or more dynamic interbody devices and/or one or more dynamic posterior stabilization systems. The dynamic interbody devices may allow for coupled axial rotation and lateral bending of vertebrae adjacent to the dynamic interbody devices. In an embodiment, the dynamic interbody device includes a keel having a neck and a cylindrical base. The cylindrical base is wider than the neck. In an embodiment, portions of the dynamic interbody device that allow for flexion and/or extension of vertebra coupled to the dynamic interbody device are coupled together by ball bearings. | 04-23-2009 |
20090105827 | Dampener system for a posterior stabilization system with a fixed length elongated member - Dynamic posterior stabilization systems are described. A dynamic posterior stabilization system may include bone fasteners and a dampener system. The dampener system may include a fixed length elongated member. The dampener system may also include one or more dampener sets. The dampener sets may provide resistance to movement of vertebrae coupled to the dynamic posterior stabilization system. In some embodiments, the elongated member has at least two portions having different diameters. The different portions interact with other portions of the dampener system to allow for compression of a dampener set. In some embodiments, the dampener system includes a sleeve coupled to the elongated member. In some embodiments, the dampener system includes a pair of washers coupled to the elongated member. The sleeve or the pair of washers allow the dampener system to be secured to a bone fastener. | 04-23-2009 |
20090105828 | Posterior stabilization system with isolated, dual dampener systems - Dynamic posterior stabilization systems and methods of stabilizing vertebrae are described. A dynamic posterior stabilization system may include bone fasteners and a dampener system. The bone fasteners may be secured to the vertebrae, and the dampener system may be attached to the bone fasteners. The dampener system may include a first dampener set and a second dampener set positioned on an elongated member. The first dampener set may be compressed and provides resistance to movement of the first bone fastener towards the second bone fastener. The second dampener set may be compressed and provide resistance to movement of the first bone fastener away from the second bone fastener. | 04-23-2009 |
20090105829 | Dampener system for a posterior stabilization system with a variable length elongated member - Dynamic posterior stabilization systems are described. A dynamic posterior stabilization system may include bone fasteners and a dampener system. The dampener system may include a first elongated member and a second elongated member that couple together to form a variable length elongated member. The dampener system may also include one or more dampener sets. The dampener sets may provide resistance to movement of vertebrae coupled to the dynamic posterior stabilization system. | 04-23-2009 |
20120143254 | POSTERIOR STABILIZATION SYSTEMS WITH SHARED, DUAL DAMPENER SYSTEMS - Dynamic posterior stabilization systems and methods of stabilizing vertebrae are described. A dynamic posterior stabilization system may include a first bone fastener configured to couple to a first vertebra, a second bone fastener configured to couple to a second vertebra, and a dampener system attached to the first bone fastener and the second bone fastener. The dampener system may include a first dampener set and a second dampener set. Compression of the first dampener set provides resistance to movement of the first bone fastener towards the second bone fastener. Compression of the first dampener set and the second dampener set provides resistance to movement of the first bone fastener away from the second bone fastener. | 06-07-2012 |
20120245689 | INTERBODY DEVICE INSERTION SYSTEMS AND METHODS - Provided is a system for implanting an interbody device into a disc space located between a first and second vertebra includes a guide frame including a guide member having an opening. The system further includes an implant trial including an elongated body and a base plate coupled to the elongated body. The elongated body of the implant trial is releasably coupled to the guide member of the guide frame during use such that the opening guides longitudinal movement of the implant trial relative to the guide frame.
