Abstract
A surgical treatment for restoring proper anatomical spacing and alignment to vertebral bones including: determining an angular misalignment associated with adjacent vertebral bones; sequentially inserting and removing a series of progressively wider cylindrical spacer elements into the corresponding intervertebral space between the adjacent vertebral bones until the proper anatomical spacing between the adjacent vertebral bones is restored; for each intervertebral space, inserting a diametrically tapered cylindrical porous spacer element into the intervertebral space between the corresponding adjacent vertebral bones; rotating the diametrically tapered cylindrical porous spacer element such that the rotational orientation of the tapered cylindrical porous spacer element introduces the appropriate counter offset to the intervertebral space of the previously misaligned scoliotic vertebral bones, thereby restoring the proper anatomical alignment of the vertebral bones; and stabilizing the adjacent vertebral bones to permit infused growth of bone into the diametrically tapered cylindrical porous spacer element.
