  • Patent number: 9962166
    Abstract: This invention is the method of treating an ailment associated with the cervical portion of the spine by performing an intravertebral corpectomy that includes the steps of removing the vertebral corpus to define a working channel for the surgeon to gain access to the epidural space so as to attend to and perform a procedure on the pathology. This method obviates the problems incidental to more radical cervical spine operations such as discectomy or corpectomy which requires removal of a portion of the vertebra and adjacent intervertebral discs for decompression of the cervical spinal cord and spinal nerves and using a bone graft with or without a metal plate and screws to reconstruct the spine and provide stability. Prior to terminating the surgery, the opening formed by the removed vertebral corpus is fitted and/or filled with a suitable implant.

The second curvature may enable the bodies to be immovably fastened to the rod in a manner that precludes the cylindrical members from contacting each other or causing a false torque condition to exist when the skeletal fixation apparatus is installed in the patient.

  • Patent number: 8945187
    Abstract: A vertebral rod for stabilizing a patient's spine. The rod may include an elongated body with first and second ends and have an elongated cross-sectional shape with a major axis and a minor axis and a centroid positioned at an intersection of the axes. First and second longitudinal channels may extend through the body. The channels may be spaced apart and contained within the body. The body may have a first flexural rigidity along the major axis and a different second flexural rigidity along the minor axis.

  • Patent number: 8906067
    Abstract: A spinal fixation device may include a bone anchoring member, a rod receiver, and an connection member. The rod receiver may include a channel for receiving a rod projection from a first adjacent fixation assembly. The rod receiver may have a central axis such that the channel is generally perpendicular to the central axis. The connection member may have a rod projection configured to extend to a second adjacent fixation assembly. The rod receiver may be coupled to the connection member and rotatable about the central axis of the rod receiver. The interior fixation assembly may be axially fixed such that the bone anchoring member, the rod receiver and the connection member are not translatably movable relative to each other.

  • Patent number: 8882806
    Abstract: A spine stabilization system is provided. The system utilizes a self-cutting rod having a sharp cutting edge that can be anchored to a patient's spine with pedicle screws. The system can be percutaneously delivered, low profile, and allow cutting of surrounding tissue rather than simply spreading the tissue apart during rod insertion.

  • Patent number: 8795336
    Abstract: A stabilization device for bone parts or vertebrae includes two bone anchoring devices for anchoring in the bone parts or vertebrae. At least one of the bone anchoring devices includes an anchoring element with an anchoring section for anchoring in a bone part or a vertebra and a head, and a receiving part for receiving a stabilization rod. The receiving part has a seat for receiving the head so that the head can pivot with respect to the receiving part. The stabilization device includes a first pressure element which is movable in the receiving part so that it can be pressed onto the head to lock the angular position of the head. The stabilization device includes at least two stabilization rod sections, and at least two guiding channels within the receiving part which have a distance from each other for guiding through the at least two stabilization rod sections so that the rod sections do not touch each other.
