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 vertebra. 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.

摘要:
A prosthetic device for insertion in a spinal column includes a first, second, and third members. The first member includes an inferiorly extending tab and is of a relatively flexible material. The second member includes a superiorly extending tab and is of a relatively flexible material. The third member defines a superior opening for receiving the inferiorly extending tab and an inferior opening for receiving the superiorly extending tab and is of a relatively stiff material. The device also includes a means for providing a rigid connection of the third member to a vertebra.
摘要:
A method of implanting a spinal prosthesis comprises inserting a first member between superior and inferior spinous processes associated with respective superior and inferior vertebrae. The superior and inferior vertebrae are separated by an intermediate vertebra. The method further includes inserting a second member through a channel in the first member. After the second member is inserted, the method requires removing the second member from the channel and inserting a third member through the channel. The third member has a different stiffness than the second member. Finally, the method requires anchoring the third member to the intermediate vertebra, while the third member is inserted through the channel. The third member is anchored at first and second locations disposed on respective first and second lateral sides of the intermediate vertebra.
摘要:
The present application is directed to methods and devices that provide for asymmetrical movement of vertebral members. In one embodiment, first and second anchors connect the rod to the vertebral members. The rod may be fixedly connected to the first anchor, and movably connected to the second anchor. A limiting device may be positioned on one or both sides of the second anchor. The limiting device or devices control an extent of movement between the rod and the second anchor during vertebral motion. In one embodiment, the device controls an amount of flexion and extension of the vertebral members.
摘要:
An interspinous process brace is disclosed and can include a superior component and an inferior component. The superior component can include a superior spinous process bracket that can engage a superior spinous process. The inferior component can include an inferior spinous process bracket that can engage an inferior spinous process. Further, the interspinous process brace can be moved between a bent configuration and a straight configuration. In the bent configuration, an overall height of the interspinous process brace can be minimized to facilitate installation between the superior spinous process and the inferior spinous process.
