摘要：
A system for fusing a spine comprises a flexion limiting tether having a superior portion, and an inferior portion. The superior portion of the device is coupled to a superior portion of the spine, and the inferior portion of the device is coupled to an inferior portion of the spine thereby constraining flexion of the spine. The system also includes bone graft for fusing the superior and inferior portions of the spine together. The bone graft is disposed between the superior and inferior portions of the spine, and the tether has a width suitable for holding the bone graft in a mass disposed between the superior and inferior portions of the spine. The tether also has a porosity suitable to allow body fluids to pass therethrough so that the graft material forms a solid mass.
