1. One Spine Surgery only
Initially if you are going to perform surgery you need to do one surgery only.
Lumbar Spine Fusion has been performed for back and leg pain before 1986 and as a
reserve for severe cases because with only a 50% success rate, it was held back for people
that really did need a surgery.
Lumbar fusion had a 50-60% success rate; new instrumentation came in around 1987 or
1988 and stabilized the spine which bumped up the success rate to 80 or 90%.
Unfortunately indications for surgery are not that clear with many physicians being overly
aggressive about back fusions. A failure of a surgery, specifically a laminectomy for
herniated disc, can be a recurrent disc which happens in 2-3% of the time. A patient who
has a failure of laminectomy and had primarily back pain and leg pain will continue to have
the same problem. Many times the disc is removed to relieve pressure on a nerve root, but
if the primary problem was back pain, generally laminectomy will not work. A failure to
diagnose the problem as a painfully generated disc as the pain generator is the problem. So
a failed lumbar laminectomy would be related to a failure of diagnosis. A back fusion for
that specific level would correct the problem. If one does a back fusion on a patient, and
does one level and not clarified other levels of pain, then if the fusion is done at one level
the others will be aggravated with time.
Generally speaking long term at 2-4 years, a patient can have about a 10% chance of
an adjacent level degeneration. In other words if you fuse one or two levels you end up
with excessive motion in another level.
Bottom line is one has to think very clearly what is going to be the outcome; what is the exit
strategy. I am not a great fan of artificial disc in lumbar spine because what happens is in
preserving the motion if the pain generator is preserved then it does not work.
Long story short though is one has to anticipate what goes on and what will have to be done
in the future should this fail. A clear indication of the pain generator can be determined by
1) pressure on the nerve root, 2) performing a discogram to diagnose a painful degenerative
disc, 3) using a facet injection to duplicate and or resolve facet pain or 4) a foraminal nerve
root injections to clarify a lateral disc with pressure on a nerve root. All these are diagnosis
that can be made clearly to ensure the correct surgery is being performed.
When these things are done as when I do my back operations, I clarify where the pain
generator is; find out what’s bothering and what’s not, and document it to the patients’
understanding before we proceed. The success rates can be as good or better then the
primary surgery if it’s done correctly.
