A spinal fusion is simply the uniting of two bony segments,
whether a fracture or a vertebral joint. The reason
for instrumentation with rods and screws is to act as
and 'internal cast' to stabilize the vertebra until
the fusion, or bony re-growth, can occur.
Historically spinal fusions have been used to correct
degenerative spondylolisthesis. However, there are many
indications for a spinal fusion and it is not the only
procedure preformed to treat those various conditions.
You should talk to your doctor about what procedure
is best for you.
There are two types of lumbar fusion. The traditional
"open" lumbar fusion achieved via a large
incision in the back, or newer "minimally invasive"
techniques that uses smaller incisions to achieve the
same results. Click on a link below to see the details
of each surgery type.
