Abstract: A spinal alignment system for interconnecting vertebral bodies is disclosed. The system includes a bone screw polyaxially connected to a seat. The seat includes a top opening, a first rod receiving portion and a second rod receiving portion, a first rod channel and a second rod channel. The system is implanted into a first vertebral body. A first rod is introduced to the seat through the top opening in a first orientation and connected to the first rod receiving portion. A second rod is introduced to the seat through the top opening in a first orientation and connected to the second rod receiving portion. The first and second rods are each moved into a second orientation such that the rods project through the first and second rod channels, respectively. The rods are capable of polyaxial movement with respect to the seat for landing the opposite ends of the rods in adjacent seats of screw systems implanted in other vertebral bodies. A closure mechanism that is configured to lock the polyaxial motion of the rods with respect to the seat and to lock the polyaxial motion of the bone screw with respect to the seat simultaneously or independently is provided. The seat is connectable to a cannula for delivering the first and second rods into the first seat in a percutaneous, minimally invasive procedure.

Abstract: Systems and devices for dynamically stabilizing the spine are provided. The systems include a superior component for attachment to a superior vertebra of a spinal motion segment and an inferior component for attachment to an inferior vertebral of a spinal motion segment. The interconnection between the two components enables the spinal motion segment to move in a manner that mimics the natural motion of the spinal motion segment while substantially offloading the facet joints of the spine. Methods are also provided for stabilizing the spine and for implanting the subject systems.

Abstract: An apparatus and method of use directed towards protective and supportive hole caps for prosthetic implant devices are disclosed. The present hole cap supports a prosthesis and provides a physical barrier between the prosthesis and underlying bone matter. In a preferred embodiment, the hole cap includes at least one compression spring formed along the perimeter of the cap. The compression spring maintains the hole cap within a counter-bored hole after the hole cap is inserted within the counter-bored hole. In accordance with the present invention, the compression spring deflects slightly towards the center of the hole cap when the cap is inserted within the counter-bored hole. The compression spring provides sufficient compression force against the sidewalls of the counter-bored hole to thereby hold the hole cap in place within the hole. The counter-bored hole is preferably shaped to snugly receive the outer perimeter of the hole cap. Alternative configurations are disclosed for maintaining the hole cap within an associated hole formed in the implant. The hole caps are used for covering holes in implants affixed to a patient's body with or without the use of bone screws. The hole caps prevent the flow of unwanted debris into the counter-bored hole and into the patient's underlying bone matter.
