摘要:
One technique of the present application includes: evaluating a patient having a previously implanted spinal construct and corresponding spinal fusion from an earlier procedure and determining a spinal segment adjacent to the spinal fusion is degenerating after completion of the earlier procedure. After this determination, the previously implanted spinal construct is augmented by attaching a flexible polymer elongated member to the spinal segment adjacent to the spinal fusion with a bone fastener and by coupling the flexible polymer elongated member to one or more elements of the previously implanted spinal construct. In one form, the elongated member is at least partially comprised of polyetheretherketone.

Devices and methods for spinal stabilization include first and second anchors engageable to respective ones of first and second vertebrae and a connector assembly engageable with the anchors to provide a desired stabilization effect. The connector assembly includes a pair of bumper assemblies extending between the bone anchors and a connecting element extending through the bumper assemblies and connecting the first and second bone anchors to one another.

Devices and methods for replacing one or more spinous processes of a patient include a replacement body with a lamina portion positionable anteriorly toward the spinal canal along with a spinous process portion extending posteriorly from the lamina portion to replace a removed spinous process. Connecting elements extend from opposite sides of the body for connection to the vertebral body with anchors.

Posterior spinal stabilization devices and methods include first and second elongate elements engageable along the spinal column and a spinous process replacement body positionable between the elongate elements. Connection mechanisms are provided to adjustably connect the spinous process replacement device to the elongate elements so that the spinous process replacement device can be moved to the desired location between the connecting elements and secured in the desired location.

Devices, instruments, systems and techniques for guiding an implant to a location adjacent a bone anchor include a guide member with a connecting portion and a guiding portion. The connecting portion is adjacent the bone anchor, and the guiding portion extends proximally from the connecting portion and is adapted guide an implant therealong toward the bone anchor. The guiding portion is flexible to facilitate manipulation and implant placement in the patient's body.
