Abstract
A fusionless method of treating spinal deformities in the spine of a child or young adult involves attaching a tether to vertebral bodies on the convex side of the spine. Deformities are treated by using the tether to selectively constrain growth in a portion of the convex side of the spine. One device for tethering the spine is a combination of a strand threaded through channels defined in a set of blocks attached to the vertebral bodies on the convex side of the spine. Another device useful in the method is to attach spinal staples, preferably made of a shape memory alloy, to vertebral bodies, the staples spanning the intervertebral disc space.
