    Abstract: Devices and methods for spinal stabilization include first and second anchor assemblies (30) engageable to respective ones of first and second vertebrae and a connecting element (40, 40', 140, 142, 144, 146, 240) engageable to the first and second anchor assemblies (30). The connecting element (40, 40', 140, 142, 144, 146, 240) includes opposite first and second members (44, 46, 244, 246) and a dampener (48, 248) between the end members (44, 46, 244, 246) that provides a flexible bumper between the end members (44, 46, 244, 246) to provide dynamic stabilization of the spinal column when engaged to the anchor assemblies (30).

    Abstract: A spinal rod having first and second end members. The end members may be flexible or rigid. An expandable intermediate section is positioned between the first and second end members. The intermediate section may be axially expandable upon the introduction of a substance into a port that may be located in either of the first and second end members or the intermediate section. The intermediate section may be expandable between a first size, where the first and second end members are spaced a first distance apart, and a second enlarged size, where the first and second end members are spaced a second greater distance apart.

    Abstract: A system (20, 120, 220) involving anchor retaining mechanisms for a bone plate includes a plate (22, 122, 222) with at least a first hole therethrough between an upper surface and a lower surface of the plate (22, 122, 222) to receive an anchor (26, 226) for engaging a bony segment. The system also includes a partially annular retaining member (28, 128, 228) engageable to the plate (22, 122, 222) and positionable in the hole of the plate (22, 122, 222) to prevent anchor backout while allowing insertion of the anchor (26, 226) through the plate hole and removal of the anchor (26, 226) from the plate hole.

    Abstract: Systems and methods for positioning a connecting element adjacent an anatomical structure in minimally-invasive surgical procedures, including an electronic guidance system associated with the connecting element and at least one receiving portion of a tissue anchor that receives the connecting element in the patient. The electronic guidance system includes a processor subsystem to receive signals from the guidance system and provide relative positional data between the connecting element and the at least one receiving portion to aid the surgeon in guiding the connecting element to the receiving portion. In one embodiment, the systems and methods are used in association with positioning a connecting element adjacent the spinal column in minimally-invasive spinal stabilization procedures.

    Abstract: An implant assembly for stabilizing a spinal motion segment includes a spacer which is at least partially flexible and positionable between adjacent spinous processes. The spacer member includes upper and lower surfaces structured to receive a respective adjacent one of the upper and lower spinous processes of the spinal motion segment and a body having flexibly distinctive first and second sections relative to one another configured to modify the manner of movement at the spinal motion segment.
