Surgery For
Back Pain
The good news about surgical
treatments for back pain is twofold: 1) Less than 1 percent of those who
suffer from back pain ever need it. 2) Medical advances have made back
surgery easier to tolerate and recover from, with more optimistic prospects
for recovery than ever before. At present, many experts agree that more
back surgery than was medically necessary was performed in the past, with
too many of the recipients not benefiting from it. Some even became worse
as a result. Today the standard for back surgery is that an individual
has a clearly defined medical condition with a specific solution that
will provide clear benefits.
Below we will look at the
three most common types of back surgery: disc surgery, spine stabilization
and creating additional space in the spine.
Disc Surgery
There are general standards
that must be met before one can be a candidate for disc surgery, a procedure
that is usually done when a disc is herniated (protrudes from its normal
spot) and causing severe discomfort.
A) An MIR or CT scan reveals
that a disc is pressing against the root of a nerve.
B) Persistent pain is experienced
despite the use of more conservative measures, such as weight loss, exercise,
and ergonomic measures.
C) Severe pain is radiating
down the leg or into the buttock, despite conservative interventions of
physical therapy or medications.
D) Neurological warning signs
are observed, such as the loss of reflexes or bodily control. These may
be indicators of a surgical emergency.
Once the need for disc surgery
has been established there are a number of approaches available:
1 Discectomy:
This is the most frequently performed back operation. In general, an incision
is made over the disc and a part, or all of it, is removed in order to
relieve pressure on the nerve.
2 Microdiscectomy:
The procedure is much the same as for a discectomy. The difference is
that a smaller incision is made because magnification is used to enlarge
the view of the target space.
3 Laser Decompression:
A needle is inserted into the disc and a portion of it is destroyed with
a laser. This relieves pressure on the nerve. The advantage of the procedure
is that it is less invasive than traditional surgeries and can be performed
on an outpatient basis.
4 Percutaneous Removal:
A small tube called an endoscope is inserted into the back and used to
remove portions of the disc. This allows the surgeon to pinpoint the problem
and leave the surrounding area intact. This, too, can be performed on
an outpatient basis.
5 Chemonucleolysis:
This is an alternative to taking out part or all of a disc. A preparation
from papaya plants, called chymopapain, is injected and has the effect
of decreasing the size of a disc, with the intention of relieving nerve
pressure.
Spine Stabilization
In this form of back surgery
two vertebrae are joined together in a process called spinal fusion. It
is accomplished by putting bone grafts either between or alongside the
vertebrae. Hollow metal cages filled with bone graft can also be inserted
between the vertebrae. The bones may be attached to the vertebrae with
metal plates or screws that serve as a brace.
Once the grafts are in place
the bones begin growing together, which serves to fuse the vertebrae.
This serves to bring normal stability and strength to structures that
have been fractured or damaged by disease.
Creating Additional
Space
The purpose of this form
of surgery is quite simple: by opening up more room for the vertebrae
pressure is taken off the affected nerve(s). Most often this is done for
patients with spinal stenosis. In this condition the spinal canal has
become too narrow, with the result being a lack of suitable space for
the spinal cord and nerves that causes pain in the back and weakness of
the legs.
In order to provide more
space a laminectomy is performed. This involves removing portions of the
laminae, the bones on the back of the vertebrae.
An Improved Process
With greater specialization
in back surgery and the ongoing development of techniques, success rates
have improved and there has been a reduction in post-surgery difficulties.
Recovery times, especially given the growth in outpatient procedures and
rehabilitation strategies, have been significantly reduced. Surgeries
that once were regarded as things we needed months to fully recover from
are now seen more as temporary interruptions, with some only requiring
a few hours.
An important point to remember
when considering back surgery is that it is only helpful when a specific
change in the anatomy of an individual’s back is called for to correct
a condition that has been clearly identified. It is not done on an exploratory
basis or because no cause has yet been found. In addition, even when the
problem has been identified, surgery is generally regarded as a last resort
and recommended only after more conservative approaches, such as medication
and physical therapy, have been attempted and judged not to be sufficient.
