Abstract
A fastener assembly including an existing polyaxial pedicle screw that has been previously installed in a spinal structure, the polyaxial pedicle screw including a polyaxial head to which a prosthetic member is secured, a fastening portion fastened to the polyaxial head over the prosthetic member, and a connector element that extends from the fastening portion, the connector element being connected to another spinal structure.
Description
- This invention relates generally to polyaxial fasteners, such as a polyaxial pedicle screw assembly, and particularly to a fastener assembly that fastens to polyaxial pedicle screws that have already been installed in spinal structure.
- Polyaxial pedicle screw assemblies are well known in the art and may be used for connecting vertebrae or other spinal structure to rods in spinal surgery. For example, polyaxial pedicle screw assemblies are known that incorporate a ball joint at the connection to the rod to allow the surgeon some flexibility in placing the screws. Tightening a nut on the screw compresses the ball joint components to lock the angular position of the ball joint.
- The present invention seeks to provide a fastener assembly that fastens to polyaxial pedicle screws that have already been installed in spinal structure, as is described more in detail hereinbelow. The fastener assembly of the present invention may be used to fasten different elements to the pedicle screws, such as but not limited to, fusion rods between adjoining vertebrae or crossbars and other connections from the pedicle screws to any suitable portion of the spine in the patient.
- The present invention provides the possibility of connecting with cross connectors to fusion systems directly to the pedicle screw and not between the fusion rods as in current prior art systems.
- There is thus provided in accordance with an embodiment of the invention a fastener assembly including an existing polyaxial pedicle screw that has been previously installed in a spinal structure, the polyaxial pedicle screw including a polyaxial head to which a prosthetic member is secured, a fastening portion fastened to the polyaxial head over the prosthetic member, and a connector element that extends from the fastening portion, the connector element being connected to another spinal structure.
- In accordance with an embodiment of the invention the fastening portion includes a wedge ring and the connector element includes a conical ring into which the wedge ring fits, the connector element including a connecting member that extends from the conical ring, wherein the wedge ring is sized to fit over the polyaxial head and the conical ring wedges the wedge ring onto the polyaxial head.
- Further in accordance with an embodiment of the invention the wedge ring has a conical periphery with a top surface that has a larger outer diameter than a bottom surface thereof, and the conical ring has a top surface with a larger inner diameter than a bottom surface thereof, the larger outer diameter not being greater than the larger inner diameter. A plurality of grooves may be formed in the conical periphery of the wedge ring. One or more of the grooves may be open at the top surface and closed at the bottom surface and one or more other grooves may be closed at the top surface and open at the bottom surface.
- In accordance with another embodiment of the invention the fastening portion includes a closed ring and the connector element includes a connecting member that extends from the closed ring, and wherein the existing polyaxial pedicle screw includes a first mechanical fastener fastened to the polyaxial head, wherein the closed ring is placed over the first mechanical fastener such that the first mechanical fastener protrudes through the closed ring, and further including a second mechanical fastener that fastens to the first mechanical fastener and is tightened against the closed ring.
- In accordance with yet another embodiment of the invention the fastening portion includes an open ring that fits over the polyaxial head and a mechanical fastener that fastens end portions of the open ring towards each other so as to clamp the open ring onto the polyaxial head, and the connector element includes a connecting member that extends from the open ring. The end portions of the open ring can be angled at an acute angle with respect to a top surface of the open ring.
- There is also provided in accordance with an embodiment of the invention a method including fastening a fastening assembly to a polyaxial head of an existing polyaxial pedicle screw that has been previously installed in a spinal structure, a prosthetic member being secured to the polyaxial head, wherein the fastening assembly includes a fastening portion fastened to the polyaxial head over the prosthetic member and a connector element that extends from the fastening portion, and connecting the connector element to another spinal structure.
