| 20080234732 | Dynamic interbody devices - A stabilization system for a human spine is provided. The stabilization system may include two dynamic interbody devices and/or one or more dynamic posterior stabilization systems. The dynamic interbody devices may be inserted into a disc space using a posterior approach. A first portion of a dynamic interbody device may contact a lower vertebra. A second portion of the dynamic interbody device may contact an upper vertebra. The first portion may be wider than the second portion to facilitate a large contact area against the lower vertebra and to facilitate insertion of the dynamic interbody device in the available space. The dynamic interbody devices may allow for coupled axial rotation and lateral bending of vertebrae adjacent to the dynamic interbody devices. The dynamic posterior stabilization systems may provide resistance to movement that mimics the resistance provided by a normal functional spinal unit. | 09-25-2008 |

| 20080234764 | Artificial functional spinal unit system and method for use - Insertion methods for placing dynamic interbody devices between a first vertebra and a second vertebra using a posterior approach are provided. In an embodiment, the insertion method may be based on the first vertebra. A bridge assembly may be attached to tap shafts positioned in the first vertebra. The bridge assembly may establish an insertion angle of implants into a disc space between the vertebrae. In an embodiment, the insertion method may be based on the position of expandable trials positioned between the vertebrae. The trials may be positioned and a bridge assembly may be coupled to the expandable trials and taps positioned in the first vertebra. One or more posterior stabilization systems may be coupled to the vertebrae after insertion of the dynamic interbody devices between the vertebrae. | 09-25-2008 |
| 20080234823 | Artificial functional spinal unit system and method for use - A method of stabilizing a human spine is provided. The spine may be stabilized by inserting one or more dynamic interbody devices in a disc space between a first vertebra and a second vertebra. A dynamic interbody device may be inserted using an anterior approach. One or more dynamic interbody devices may be inserted using a posterior approach. One or more of the dynamic interbody devices may allow for coupled axial rotation and lateral bending of the first vertebra relative to the second vertebra. The spine may also be stabilized by installing one or more posterior dynamic stabilization systems. | 09-25-2008 |
| 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 |

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 |
