Patent number: 8142481Abstract: The pedicle screw system may be used for fixation of spinal segments and may be advantageous when minimally invasive surgery (MIS) techniques are employed. The pedicle screw system includes a tulip assembly comprising of a tulip body, an inner member, and an expansion member. Installation of the pedicle screw system into pedicles of the spine, for example, includes inserting the pedicle screw into a portion of the spine and then coupling the tulip assembly to the pedicle screw. The tulip assembly may be locked onto the pedicle screw before a distraction rod is placed in the tulip assembly. After the rod is placed in the tulip assembly, the tulip body and the inner member can be rotated relative to one another to lock the rod into the tulip assembly. In addition, the relative rotation may also provide additional locking of the tulip assembly to the pedicle screw.Type: GrantFiled: January 21, 2010Date of Patent: March 27, 2012Assignee: X-spine Systems, Inc.Inventor: David R.

Patent number: 8097025Abstract: A fastener and a bone fixation assembly for the internal fixation of vertebral bodies such as a pedicle screw is provided which allows a detachable tulip to be provisionally locked to a pedicle screw in a first position, while securely locking the tulip assembly to the pedicle screw when in a second position. According to one exemplary embodiment, the tulip assembly includes a tulip body, a coupling saddle, and an expansion ring serving as a fastener. The fastener secures the tulip body to the pedicle screw, while the coupling saddle provides a means to provisionally lock the tulip body at an angle relative to the pedicle screw via an interference fit. Incline planes on the walls of the tulip body provide means to rotationally lock a rod within the tulip assembly, and fully lock the tulip assembly to at an angle relative to the pedicle screw.Type: GrantFiled: March 27, 2008Date of Patent: January 17, 2012Assignee: X-spine Systems, Inc.Inventors: David T.
