    Abstract: Methods, apparatus and systems for constraining spinous processes to elastically limit flexion of two or more adjacent spinal segments rely on placing a tether structure over at least three adjacent vertebral bodies or two adjacent vertebral bodies and the sacrum. The tether structures may be continuous, for example in the form of a continuous loop, or may be discontinuous, for example in the form of a loop or elongate element having at least two anchor structures for securing in bone.

    Abstract: Methods and apparatus for controlling flexion in a spinal segment of a patient include performing a spinal fusion procedure on a pair of adjacent vertebrae in the spinal segment and implanting a constraint device into the patient. Adjusting length or tension in the constraint device allows the constraint device to provide a force a force resistant to flexion of the spinal segment undergoing fusion. The constraint device also modulates loads borne by the spinal segment undergoing fusion or tissue adjacent thereto.

    Abstract: A spinal implant for limiting flexion of the spine includes a tether structure for encircling adjacent spinal processes. Usually, a pair of compliance members will be provided as part of the tether structure for elastically limiting flexion while permitting an extension. A cross-member is provided between the compliance member or other portions of the tether structure to stabilize the tether structure and prevent misalignment after implantation.

    Abstract: A method for improving shear loading capacity of a spinal segment having a superior vertebra, an inferior vertebra or sacrum, and a facet joint, includes providing a constraint device having an upper portion, a lower portion and a compliance member coupled therebetween. The constraint device is coupled with the spinal segment such that the upper portion of the constraint device is coupled with the superior vertebra and the lower portion of the constraint device is coupled with the inferior vertebra or a sacrum. The constraint device provides a force resistant to flexion of the spinal segment. Also, length or tension in the constraint device is adjusted so as to increase engagement between an upper portion of the facet joint and a lower portion of the facet joint, thereby increasing capacity of the spinal segment to resist shear loading.

    Abstract: An exemplary method for constraining spinous processes to elastically limit flexion of a spinal segment comprises piercing an interspinous ligament to form a first penetration above an upper side of an upper spinous process and advancing a first end of a first tether through the first penetration. The interspinous ligament is pierced again to form a second penetration below a lower side of a lower spinous process and a second end of a second tether is advanced through the second penetration. Joining the first and second tethers together forms an extensible tether structure coupling the upper and lower spinous processes together while permitting extension therebetween. Adjusting the tether structure sets relative distance or angle between the upper and lower spinous processes to a target value.
