One or more sutures can be used in spinal applications to hold an intradiscal device in place between two vertebrae or repair a defect in the soft tissue of the spine, such as the annulus fibrosis or the dura. Tension can also be applied to the sutures to stabilize a spinal segment having an intradiscal device to prevent or minimize excessive spinal extension, lateral bending, and axial rotation of the spinal segment. Anchors are placed in two adjacent vertebrae and sutures are passed through each anchor. The sutures can be passed through portions of the intradiscal device, Alternatively, the sutures can be passed through a mesh patch which is held against the vertebrae to hold the intradiscal device in place. Tension is applied to the first and second ends of the sutures and the sutures are welded together. The sutures can be welded in a cross-braced arrangement minimize or prevent extension, lateral bending, and rotation of the spinal segment. For example, the sutures can be welded in a diagonal pattern, a horizontal pattern, a vertical pattern or any combination thereof across the adjacent vertebrae.
