|20100217319||SYSTEM AND METHOD FOR SPINAL STABILIZATION - Various stabilization rods and methods for manufacturing a connection member having a flexible section coupled between two rigid sections are disclosed. The rigid sections may have exterior surfaces adapted to have an increased surface area to inhibit the flexible section from separating from the rigid sections.||08-26-2010|
|20100160968||SYSTEMS AND METHODS FOR PEDICLE SCREW-BASED SPINE STABILIZATION USING FLEXIBLE BANDS - Embodiments of the disclosure provide a spinal stabilization rod useful for connecting a set of bone fasteners that can anchor a spinal stabilization system onto vertebral bodies. The spinal stabilization rod comprises rigid sections for coupling with bone fastener assemblies engaged in vertebrae and a flexible band for coupling the rigid sections. A bumper may be disposed around the rod to encase the flexible band. The spinal stabilization system may include a dampener.||06-24-2010|
|20100152785||COAXIALLY LOCKABLE POLY-AXIAL BONE FASTENER ASSEMBLIES - A poly-axial bone fastener assembly having a collar and a bone fastener can be coaxially locked to prevent poly-axial movements of the collar relative to the bone fastener while permitting the collar to rotate about an axis of the bone fastener, thereby combining the functions and advantages of a poly-axial bone screw and a fixed angle bone screw. Some embodiments of a coaxial locking mechanism may include a c-clip with a locking pin, a c-clip with hooks, a split ring with square corners, a pin that spins inside the collar, pins that travel about a neck of the bone fastener, a coaxially locking top that screws into the collar over a head of the bone fastener, and a top nut that threads onto the head of the bone fastener inside the collar to trap a flange of the collar between a shoulder of the bone fastener and the top nut.||06-17-2010|
|20100114165||POSTERIOR DYNAMIC STABILIZATION SYSTEM WITH PIVOTING COLLARS - A dynamic spinal stabilization system. The system can include a spinal stabilization rod and a pivoting collar which can be attached to a vertebra. The pivoting collar can define a bore which has internal surfaces and corresponding contact points. The bore can accept the rod and allow it to pivot about a contact point. The internal surfaces can be structured, shaped, and dimensioned to limit the range of motion of the rod in some or all directions. One portion of the rod can be flexible while another portion of the rod can be flexible. The flexible portion of the rod can engage the pivoting collar and bend within the pivoting collar to provide a greater range of motion.||05-06-2010|
|20100057131||POLYAXIAL TRANSVERSE CONNECTOR - A polyaxial transverse connector for stabilizing a portion of the spine. Connector bodies are coupled to rods attached to either side of the spine. Heads of transverse members are positioned in the connector bodies such that they exhibit polyaxial motion. The transverse members may have curves or offsets to accommodate other components or patient anatomy. A connector connects the transverse members and male threaded inserts are advanced into the connector bodies to inhibit motion of the polyaxial transverse connector.||03-04-2010|
|20100036434||RESCUE REDUCTION BONE ANCHOR - Systems and methods for reducing spinal stabilization rods. One embodiment provides an instrument including a body (defining a threaded slot for receiving the spinal stabilization rod), an alignment feature, and a flange (for mounting the instrument on a bone anchor), each of which can correspond to portions of the bone anchor. The alignment feature can align the threads of the instrument and bone anchor to form substantially continuous threads. The alignment features can be a pin and a hole oriented radially with respect to the instrument. An actuator can actuate the instrument alignment features toward, or away from, the instrument body. An actuator slot can correspond to the instrument slot. The threads of the instrument slot can include a thread diameter transition portion. In some embodiments, the instrument threads can include an anti-splay feature which mitigates reaction moments arising from the reduction of the spinal stabilization rod.||02-11-2010|
|20100036432||TWIST OFF REDUCTION SCREW - Methods and systems for reducing spinal stabilization rods. In one embodiment, a method can include attaching a collar to a boney structure. The collar can include a body and an extension, each including arms further defining threaded slots. A separation member can couple the body and the extension to each other. The method can include reducing the rod using the collar and separating the extension from the body by applying a torque to the extension. The separation of the extension from the body can be accomplished with one substantially continuous motion and can leave tissues adjacent to the collar substantially undisturbed. The arms of the extension can be prevented from splaying, thereby mitigating a moment during the reduction of the spinal stabilization rod through the extension. Thus, the separation member can transmit tensile forces and certain amounts of torques between the body and the extension.||02-11-2010|
|20100024487||Surgical Instrument With Integrated Reduction And Distraction Mechanisms - Embodiments of a surgical instrument disclosed herein can include mechanisms for reduction and distraction as well as compression. Some embodiments of the surgical instrument may comprise a reducer knob having a first passage through which a first shaft of a driver is acceptable, a connecting element coupled to the reducer knob and having a second passage through which the first shaft of the driver is acceptable, a compressor handle coupled to the connecting element at a first end and having a through hole, and a common handle coupled to the compressor handle via the through hole and pivots between the reducer knob and the compressor handle. With embodiments of a surgical instrument disclosed herein, surgical personnel can distract and hold vertebrae in a distracted state and perform a reduction without having to switch or add instruments. Some embodiments disclosed herein can be particularly useful for reducing spondylolisthesis during posterior fixation.||02-04-2010|
|20090138047||TRANSVERSE CONNECTOR WITH CAM ACTIVATED ENGAGERS - An adjustable transverse connector connects orthopedic stabilization rods that may be parallel or skewed in orientation relative to each other The connector may include two sections that are joined together by a fastener. The connector may be adjustable in many ways. The overall length of the connector may be adjustable. The rod openings of the connector may be partially rotatable about a longitudinal axis of the connector. The two sections of the connector may be angulated. The connector may include cam locks that securely attach the connector to the rods. Rotating a cam lock may extend a rod engager into a rod opening. The rod engager may be a portion of the cam lock. The extension of the rod engager into a rod opening may push a rod against a body of the transverse connector to form a frictional engagement between the connector, the rod, and the rod engager.||05-28-2009|
|20080288002||Spinal Stabilization Systems and Methods - One embodiment provides a bone fastener including a collar, a fastener member, and a pin. The collar can have an upper portion with slot to receive an elongated member and a lower portion with a socket and an opening. The fastener member can have head and shank portions. The socket can receive the head portion and prevent movement of the head portion through the opening when the head portion is out of registration with the opening. The head portion and the socket can be configured to allow angulation of the fastener member within a defined range of motion within a selected plane. The head portion and the socket can define apertures which can be aligned with each other when the head portion is in the socket and which can receive the pin. One embodiment provides a generally spherical head portion with a flat.||11-20-2008|
