Dynamic spinal plating system

摘要

Dynamic spinal plating systems that can be placed on the anterior aspect of the spine to aid in spinal fusion and surgical methods for using the dynamic spinal plating systems are disclosed. The dynamic spinal plating systems including a plate and at least one bone attachment mechanism. The plate including a superior end with at least one screw hole, an inferior end, and two lateral sides forming an opening that is transverse by the bone attachment mechanism. The dynamic spinal plating systems also include at least one screw plate with a center screw hole and two passageways that mate with two transverse members of the bone attachment mechanism. When implanted the vertebral stabilization devices may provide a degree of movement in the superior-inferior direction providing for a minimal change in length as the patient moves and as vertebral body height decreases.

主权项

1. A dynamic spinal plating system comprising:
a plate with a superior end, an inferior end, and first and second lateral sides that connect the superior end and inferior end and form an opening therebetween that is elongated along a first direction extending between the superior and inferiors ends, wherein the superior end includes at least one through hole, and wherein the first and second lateral sides each include a slot that extends therethrough and along the first direction; and at least one bone attachment mechanism extending transverse to and within the opening between the first and second lateral sides of the plate, wherein the at least one bone attachment mechanism comprises:
a pair of transverse members;a first locking mechanism coupled to a first end of the pair of transverse members and positioned on a side of the first lateral side opposite the opening; anda second locking mechanism coupled to a second end of the pair of transverse members and positioned on a side of the second lateral side opposite the opening; wherein the pair of transverse members is spaced along the first direction and the pair of transverse members pass through the slots of the first and second lateral sides to allow the pair of transverse members to slide along the first direction within the opening.
