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 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.
