Abstract
An implantable spacer body (44) configured to be positioned between the spinous process portions of adjacent vertebrae in such a manner that the spinous process of the superior vertebra rests on and is supported on the spacer body. A pair of extension arms (54, 56) extend from each side of the spacer body and are adapted to be fixed to bone fasteners (86) which engage a region of the inferior vertebral body in locations other than the spinous process, preferably engaging the pedicle regions of the inferior vertebra. Alternatively, the extension arms can be fixed to spinal rods (90, 92) that are fastened to multiple vertebrae in a typical spinal rod assembly.
