    摘要： A dynamic stabilization construct for implantation within the spine comprises bone anchors that include a flexible portion between the bone engaging and head portions of the anchor. The head portion is configured to mate with different types of stabilization elements adapted to span between spinal motion segments. The engagement portion can also be configured for different types of fixation to a motion segment, such as within the pedicle of a vertebra. The flexible portion permits limited bending of the bone anchor beneath the level of the stabilization element. In one embodiment, the flexible portion is integrated into the body of the bone anchor in the form of hinge elements. In another embodiment, a separate flexible element, such as a spacer or spring, is interposed between the head and engagement portions. In a further embodiment, the bone anchor includes a portion having a reduced cross-section. The flexible bone anchors may be used to tailor the dynamic flexibility of spinal stabilization instrumentation at each level of the construct.

    摘要： A dynamic stabilization system includes a stabilization element, such as a spinal rod, a plurality of bone anchors, such as bone bolts, and a like plurality of connectors for connecting the bolts to the spinal rod. At least some of the connectors include a flexible element between the bone anchor and the rod and an adjustment element for adjusting the flexibility of the flexible element, to thereby adjust the dynamic flexibility between the rod and the bone anchor. In one embodiment, the flexible element is a flexible bearing element of a rod end bearing.

    摘要： A method for treating a diseased or damaged spinal disc comprises the steps of: (a) providing access to the nucleus pulposus through the annulus; (b) removing at least a portion of the nucleus pulposus to create an intradiscal space; determining the size of the intradiscal space; and (c) sealably introducing under pressure a curable biomaterial through the annulus directly into the intradiscal space. The method may include the additional steps of applying a force to distract the opposing vertebral bodies about the intradiscal space and then removing the distraction force after the biomaterial has cured. The step of determining the size of the intradiscal space may be accomplished by expanding a compliant balloon within the intradiscal space using a contrast medium capable of visualization under fluoroscopy. The curable material is sealably introduced through a vented needle inserted through the opening. The curable biomaterial is introduced until a quantity of the material flows into the vent.

    摘要： A method for treating a herniated spinal disc between opposing vertebral bodies having a damaged outer annulus and an inner nucleus pulposus comprises the steps of: providing access to the nucleus pulposus through the annulus; removing at least a portion of the nucleus pulposus to create an intradiscal space; applying a first distraction force on the opposing vertebral bodies from within the intradiscal space; applying a second distraction force on the opposing vertebral bodies externally of the intradiscal space; and introducing a curable biomaterial through the annulus access directly into the intradiscal space. The first distraction force is applied within the disc space to distract the anterior aspect of the intradiscal space, while the second distraction force is applied exterior to the disc to act on the posterior aspect of the vertebral bodies. The first distraction force is applied prior to the application of the second distraction force and then removed. The second distraction force is maintained during the introduction of the biomaterial into the intradiscal space.

    摘要： A method for treating a spinal disc comprises the steps of: determining the integrity of the annulus by subjecting the annulus to a first pressure applied internally of the annulus; providing access to the nucleus pulposus through the annulus without removing any tissue from the annulus or from the nucleus pulposus; and sealably injecting curable biomaterial through the annulus access directly into the nucleus pulposus at a second pressure correlated with the first pressure. The integrity of the annulus may be determined by a pre-operative discogram using a contrast medium that has a viscosity substantially similar to the viscosity of the biomaterial to be injected. The curable biomaterial may be injected under a pressure sufficient to distract opposing vertebral bodies communicating with the disc space.
