  • Publication number: 20070191834
    Abstract: Devices and methods for attaching a support to the sacrum. One device may include first and second anchors that mount to the sacrum, and first and second lateral extensions coupled to the anchors to secure the device to the sacrum. A bearing face having a width is positioned between the lateral extensions. The face may have a height in an anterior-posterior direction greater than the spinous process of the sacrum. Further, the bearing face may be oriented in a superior direction when the device is mounted to the sacrum. An implant may be supported by the device to space the sacrum and L5 vertebrae. The implant may be an interspinous device and positioned between the L5 spinous process and the bearing face. The implant is supported at least in part by the bearing face.

  • Publication number: 20070191838
    Abstract: The present application is directed to devices and methods for spacing apart spinous processes. In one embodiment, the device includes a body having a central portion that separates first and second sections. The body is constructed of a combination of an elastic material and a bio-absorbable material. When initially implanted within a patient, the bio-absorbable material affects the stiffness of the device. The device stiffness changes to that of the elastic material as the bio-absorbable material is absorbed by the body.

  • Publication number: 20070191833
    Abstract: A method spacing spinal elements includes installing a first spinal implant having a sensor associated therewith; selecting a second spinal implant based on measurement data provided by the sensor; and replacing the first spinal implant with the second spinal implant. The first and second implants may be installed in separate surgical procedures, or during the same surgical procedure, and the implants may be positioned between a superior spinous process and an inferior spinous process and advantageously directly engage the same. The selection of the second implant may be based on the data provided by the sensor and a material property of the second spinal implant, such as its stiffness. The measurement data may correspond to strain or force data. The sensor may be, but is not required to be, embedded in the first spinal implant. A corresponding apparatus is described.

  • Publication number: 20070191846
    Abstract: A spinal rod having first and second end members. The end members may be flexible or rigid. An expandable intermediate section is positioned between the first and second end members. The intermediate section may be axially expandable upon the introduction of a substance into a port that may be located in either of the first and second end members or the intermediate section. The intermediate section may be expandable between a first size, where the first and second end members are spaced a first distance apart, and a second enlarged size, where the first and second end members are spaced a second greater distance apart.

  • Publication number: 20070100340
    Abstract: A prosthetic device and a method of implanting same between two vertebrae of a vertebral column to stabilize the column, according to which each vertebrae is engaged by a spacer, and the spacers are connected to permit relative movement between the spacers so that the distance between the spacers can vary to conform with the distance between the vertebrae and accommodate bending movements of the vertebral column.

  • Publication number: 20070027545
    Abstract: One embodiment of the present application includes: performing a medical procedure on a segment of a patient's spine. This segment includes two vertebrae each in contact with a spinal disk positioned in an intervertebral disk space. A passage is formed that follows a pathway through the vertebrae and the intervertebral disk space. This passage extends from an extradiscal opening through one of the vertebrae along a path that turns to change direction. The tubular device is inserted in the passage and extends through the intervertebral disk space. A fluid material is introduced into the tubular device to at least partially fill it to provide a spinal prosthetic structure. Other embodiments and inventive aspects include other prosthetic device arrangements, implantation methods, systems, and techniques.

  • Publication number: 20070005062
    Abstract: Systems and methods for multi-directional stabilization of a spinal column segment are provided. The systems include one or more motion preserving constructs that are engaged to adjacent vertebrae and extend trans-axially between the vertebrae obliquely to the central axis of the spinal column. The systems permit motion of at least a portion of a vertebral level while providing stabilization at least when tensioned. Systems that provide stabilization in compression are also contemplated.

  • Publication number: 20060247625
    Abstract: One technique of the present application includes: evaluating a patient having a previously implanted spinal construct and corresponding spinal fusion from an earlier procedure and determining a spinal segment adjacent to the spinal fusion is degenerating after completion of the earlier procedure. After this determination, the previously implanted spinal construct is augmented by attaching a flexible polymer elongated member to the spinal segment adjacent to the spinal fusion with a bone fastener and by coupling the flexible polymer elongated member to one or more elements of the previously implanted spinal construct. In one form, the elongated member is at least partially comprised of polyetheretherketone.

  • Publication number: 20060247623
    Abstract: A posterior spinal fixation device or dynamic spinal stabilization device or other orthopedic device includes an active agent-delivery component. The active agent-delivery component has an active agent impregnated therein or adsorbed thereon or otherwise contained therein and is configured to release the active agent locally after the device is implanted in a patient. One preferred type of implant in accordance with the invention is an implant for stabilizing a spinal motion segment that includes a spacer member positionable between adjacent spinous processes or transverse processes or other posterior spinal element, including an implanted anchor element.

  • Publication number: 20060247782
    Abstract: One embodiment of the present application includes a spinal disk prosthesis with one end portion to form a load transmitting relationship with one vertebra of a patient's spine and another end portion to form a load transmitting relationship with another vertebra of the patient's spine. A tube connects the end portions together and a damping material is positioned inside the tube. The end portions each include a magnet to generate a corresponding magnetic field. These magnetic fields are oriented to provide a repulsive force between the end portions to provide a magnetic bearing.

  • Publication number: 20060241626
    Abstract: A series of instruments (30, 80, 120, 210, 510, 550) are provided for direct-anterior and oblique-anterior disc space and end plate preparation. The instruments (30, 80, 120, 210, 510, 550) provide precise guidance for channel formation in the vertebral endplates by guiding rotating and bladed cutting instruments (122, 250, 580). Instrumentation (550) for oblique-anterior disc space preparation includes compound angulation to account for the angle of approach to the spine and the angulation between adjacent vertebrae. Methods and techniques for use of the instruments (30, 80, 120, 210, 510, 550) are also described.
