Back Surgery

Back pain is
extremely common, and surgery often fails to relieve it.
Find out why your back hurts and whether surgery might help.
Oh, your aching back. Not simply an ache. This pain is
serious. You wonder if back surgery could end the discomfort
once and for all.
Trauma, aging, improper body mechanics, and normal wear
and tear can all injure your spine. And damage to any part
of your back — especially damage that puts pressure on your
nerves — can cause pain and other symptoms.
Most back problems respond to nonsurgical treatments,
such as anti-inflammatory medication, ice, heat, gentle
massage and physical therapy. When conservative treatments
don't help, back surgery may offer relief. But it doesn't
help every type of back pain. In fact, back surgery is
needed in only a small percentage of cases.
Do you need back surgery?
Most people will have back pain sometime during life. And
90 percent of these people will get better, without
treatment or with conservative therapy for four to six
weeks. Only 5 percent remain disabled longer than three
months.
In most situations, an operation won't be considered
unless conservative measures have failed, and even then
surgery is not often indicated. Back surgery is usually
reserved for times when spinal nerves are compressed,
causing numbness along the back of your leg.
Many types of problems can reduce the amount of space in
the spine, so nerves become pinched. The disks separating
the bones in your spine can also bulge or rupture
(herniate), which can irritate nearby nerves. However, many
people with bulging disks have no pain.
To relieve pressure on the spinal cord or nerves,
surgeons can remove portions of bone to widen the narrowed
area in the vertebrae. Removing the gel-like interior of
ruptured disks also helps relieve pressure on pinched
nerves. Sometimes the entire disk must be removed, with the
adjoining vertebral bodies fused together surgically.
Bone fractures and
deformities
Direct injury to the spine may cause a bone fracture
anywhere along your vertebral column. Osteoporosis — loss of
bone density — can weaken vertebrae, causing them to
fracture or collapse.
In most cases, fractured vertebrae heal without any help.
But if the spinal column is unstable, some doctors opt to
fuse two or more vertebral bodies together, using bone
grafts and metal plates, screws, rods, or cages.
The following conditions may require surgery if they're
progressive, painful or causing nerve compression:
- Scoliosis, a curvature of the spine
- Kyphosis, a humpback deformity
- Spondylolisthesis, the forward slippage of a segment
of the spine
- Spinal stenosis, narrowing of the spinal canal
typically from arthritis
- Radiculopathy, the irritation and inflammation of a
nerve caused by a herniated disk
- Degenerative disk disease, the development of pain
in a disk as a result of its normal wear and tear
Types of back surgery
Different types of back surgery include:
- Discectomy. This involves removal
of the herniated portion of a disk to relieve irritation
and inflammation of a nerve. It's done as an open
surgery and typically involves full or partial removal
of the back portion of a vertebra (lamina) to access the
ruptured disk.
- Laminectomy. This procedure
involves the removal of the bone overlying the spinal
canal. It enlarges the spinal canal and is performed to
relieve nerve pressure caused by spinal stenosis.
- Fusion. Spinal fusion permanently
connects two or more bones in your spine. It can relieve
pain by adding stability to a spinal fracture. It is
occasionally used to eliminate painful motion between
vertebrae that can result from a degenerated or injured
disk.
- Vertebroplasty. During this
procedure, your surgeon injects bone cement into
compressed vertebrae. For fractured and compressed
vertebrae, this procedure can help stabilize fractures
and relieve pain. With a similar but more expensive
procedure — called kyphoplasty — a balloon-like device
is inserted to attempt to expand compressed vertebrae
before bone cement is injected.
- Artificial disks. Implanted
artificial disks are a treatment alternative to spinal
fusion for painful movement between two vertebrae due to
a degenerated or injured disk. These relatively new
devices are still being studied, however, so it's not
yet clear what role they might play in treating spinal
disk disease.
Consider all your options
Before you agree to back surgery, consider getting a
second opinion from a qualified spine specialist. Spine
surgeons hold differing opinions about when to operate, what
type of surgery to perform, and whether — for some spine
conditions — surgery is warranted at all. Back and leg pain
can be a complex issue that may require a team of health
professionals to diagnose and treat.
To prevent recurrent back problems, use good body
mechanics, keep your back muscles conditioned with regular
exercise and stretching, control your weight and don't
smoke.
