Abstract:
1. A fusion device comprising a plurality of fasteners adapted to couple a plurality of housings to vertebral bodies and a plurality of rods coupled to the housings and adapted to extend longitudinally between vertebral bodies to promote fusion between the vertebral bodies, the fusion device further comprising at least one cross-link between the plurality of rods, the improvement comprising: an extension coupled to the cross-link, the extension adapted to traverse an adjacent intervertebral disc space and reside proximate an adjacent vertebra in selective abutment with the adjacent vertebra, such that the extension provides an extension stop to resist movement of the adjacent vertebra in extension while allowing movement of the adjacent vertebra in flexion such that bone fusion across the adjacent intervertebral disc is inhibited; and a flexible band connected to the cross-link and adapted to connect the extension to the adjacent vertebra; wherein at least one through hole extends through the extension and the flexible band extends from the cross-link through the at least one through hole.
