A spinal stabilization system generally comprises first and second anchor members configured to be secured to first and second vertebrae within a patient's body, a flexible element secured to the first anchor member, and a rigid element secured to the second anchor member. An end portion of the rigid element is coupled to an end portion of the flexible so that the system is able to provide both rigid and dynamic stabilization. The coupling is maintained even if the flexible element relaxes after a period of time within the patient's body.

A bone anchor system anchors a support member to a bone. The bone anchor system comprises a body having a shank adapted for insertion into a hole in the bone. A head is formed on the shank. The head has a support engagement portion adapted to secure the support member to the body. A passage extends from an entry point to an exit point formed in the body. An expandable member has a flexible wall at least partially enclosing an anchoring chamber. The expandable member has an expanded state configured to conform to a cavity in the bone. The anchoring chamber is in fluid communication with the exit point. The expandable member is adapted to expand when a filler material is provided into the anchoring chamber. A portion of the expandable member conforms to the cavity and the body and the support member are substantially anchored to the bone.

An intervertebral endoprosthesis for insertion into the intervertebral space between two adjacent vertebrae is provided that includes first and second base members, each having a first surface configured to engage one of the vertebrae and a second opposite surface and a resilient insert disposed between the base members. The insert includes an outer shell defining an interior chamber and is disposed in contacting engagement with the second surface of each of the base members. The resilient insert further includes a core disposed within the chamber and connected to the outer shell. The intervertebral endoprosthesis further includes first and second coupling members, each of the coupling members extending between the core of the resilient insert and one of the base members. The first and second coupling members independently couple the first and second base members to the resilient insert, wherein the first and second base members are movable independently of one another and the adjacent vertebrae are movable independently of one another when the intervertebral endoprosthesis is inserted into the disc space.

A spacer for maintaining separation between adjacent spinous processes having a first and second end support, a connecting member, and a central member positioned between the first and second end supports. The spacer is adjustable between a collapsed configuration and an expanded configuration such that when the connection member is pulled to bring the first and second end supports closer together, the central member expands into the expanded configuration to contact and support adjacent spinous processes.
