Particular Shaped Rod Patents (Class 606/261)
  • Publication number: 20100106193
    Abstract: A system and method for ameliorating spinal column anomalies, such as scoliosis, while accommodating growth of juvenile patients, includes pedicle screws and a spinal rod of non-circular cross section. Each pedicle screw includes spinal rod engagement mean for achieving a slide-only engagement between each segment of said spinal rod that is respectively engaged with the pedicle screw. Pedicle screws are thereby allowed to slide longitudinally along the spinal rod as attached vertebrae move during growth, while movement in other directions is arrested in order to preserve a proper orientation of involved vertebrae to maintain scoliotic correction in three dimensions.

  • Publication number: 20100063544
    Abstract: A spine or spinal rod has a cross-section defining angled sides that cooperate with a spinal rod opening of a spinal rod holder. In one form, the spine rod has an essentially pentagonal cross-section that thus essentially defines angled sides or side surfaces that interact with the spinal rod holder opening to positively seat the spine rod into the spinal rod holder and prevent spine rod from rotation. In the pentagonal cross-section form, the spine rod has a top or posterior side/side surface, a bottom or anterior side/side surface, a first lateral side/side surface, a second lateral side/side surface, a first angled sub-lateral side/side surface and a second angled sub-lateral side/side surface. The first and second angled sub-lateral sides/side surfaces provide contact with angled sides of the spine rod holder opening. In another form, the spine rod has an essentially V-shaped cross-section that defines sides/side surfaces that interact with the spinal rod holder opening.

  • Patent number: 7632293
    Abstract: A damping element for the dynamic stabilization of two bones, particularly of two adjacent bodies of the vertebra, includes a flexible spring element having a hollow space. The hollow space is open on a first end and closed on a second end by a wall extending transversely to the longitudinal axis of the damping element. A clamping sleeve is inserted at least partially into the hollow space. The sleeve has a front end directed towards the wall of the flexible spring element. The distance between the front end and the wall affects the damping characteristics of the damping element. A coaxial connecting element is attached to each end of the flexible spring element. Each connecting element is configured to be connected within an osteosynthetic stabilizing device.

  • Patent number: 7597707
    Abstract: A pedicle screw with a closure device including a seat element and a closure cap for quick closure of the seat element of the pedicle screw. An elastic rod element inserted therein in the seat recess, which element serves to stabilize a vertebral column, is held in a form-locking way. The closure cap of the closure device has the function of a cross-brace, and can transfer the forces absorbed by it from the rod element to the pedicle screw. Disposed on the closure cap with a holding recess are engagement elements which, during insertion of the closure cap, automatically lock in place in a stable position in the seat element provided with a U-shaped seat recess. The seat recess and the holding recess preferably have a ridged or grooved structure corresponding to the rod element used.

  • Publication number: 20080275506
    Abstract: A spinal implant for insertion in the intervertebral space is formed as a hollow cage, wedge shaped in profile, with a lesser height leading end for a low profile entry. The cage has two open sides with a plurality of angled teeth along opposite longitudinal edges for engaging the end plates of adjacent vertebrae when the cage is rotated into position. One portion of the angled teeth is angled toward an end of the cage and another portion of the angled teeth is angled away from that end to provide a lock preventing the cage from migrating ventrally or dorsally from the spine. Upon rotation, the leading end has a greater height than the trailing end. Opposing side walls of the cage include recesses to facilitate rotation of the cage and minimize stress on adjacent vertebrae.

    Abstract: The present application is directed to vertebral rods constructed for vertebral movement in first and second planes, and to prevent or inhibit vertebral movement in a third plane. The vertebral rod may include one or more notches. The notches change the cross section shape of the rod and thus the structural characteristics. The notches may be shaped, sized, and positioned to facilitate vertebral movement in the first and second planes, and prevent or inhibit movement in the third plane. A fill material may be positioned within the notches to strengthen the rod and/or provide durability.
