Spinal instrumentation without fusion for
scoliosis involves attaching devices (such as metal
rods, hooks, wires, and screws) in or near the spine to correct a spinal curve
without actually fusing the vertebrae together. The goal of this surgical
procedure is to stabilize a severe spinal curve in a growing child without
fusing an area of the spine that would stop growth in that area.
This procedure is used, with some limitations, on children who are
still growing and have severe spinal curves that are getting worse.
Benefits of this procedure include that
it:
- Allows for normal vertical growth of the
spine.
- May stabilize a severe spinal curve.
- Prevents a
spinal curve from getting worse.
Limitations of this procedure include:
- Possible complications from surgery, such as
devices that do not stay in place or break, the need to remove devices due to
infection or other problems, or the need for another surgery.
- The
need for several surgeries (as many as six surgeries, or two surgeries per
year).
- The need to wear a full-time brace.
Spinal fusion surgery is necessary when the child is nearly finished
growing.
Despite these limitations, the development and use of instrumentation
without fusion is an important alternative for some children with severe
scoliosis who are still growing.
