    摘要： A bone anchor including a bone engaging element and an implant engaging element. The bone engaging element includes a first portion formed of a first material and a second portion formed of a second material and extending at least partially along a length of the first portion, and with the second portion of the bone engaging element positioned between the first portion and adjacent bone tissue when the bone engaging element is engaged with the bone to provide an interface with the adjacent bone tissue. In one embodiment, the first portion of the bone engaging element exhibits a first level of rigidity and the second portion exhibits a second level of rigidity less than the first level of rigidity. In another embodiment, the bone engaging element includes external threads, with the second portion of the bone engaging element defining at least a portion of the external threads.

    摘要： A bio-compatible stabilization system includes one or more inserters and a connector for traversing a space between one or more bony structures. The stabilization system is designed to reduce or eliminate stress shielding effects while functioning as a tension band. The elastic properties of the connector can be selected and set on a per-patient basis to allow variance in range of motion and to tailor the connector to the particulars of a patient, i.e., age, gender, weight, height, condition, and the like.

    摘要： Devices and methods include a multi-axial anchor assembly engageable to a vertebra and a connecting element positionable through a receiver of the anchor assembly. The anchor assembly includes a flexible member between the receiver and an anchor member of the anchor assembly, thereby providing a flexible joint in the anchor assembly for allowing limited movement after primary multi-axial capability between the receiver and the anchor member has been arrested.

    摘要： Methods and devices retract tissue for minimally invasive surgery in a patient. A retractor includes a working channel formed by a first portion and a second portion. The first and second portions are movable relative to one another from a first configuration for insertion that minimizes trauma to skin and tissue to an enlarged configuration after insertion to further retract skin and tissue in a minimally invasive manner. An optional intermediate retractor assembly is positionable between the first and second retractor portions to provide further tissue retraction capabilities.
