What Causes Back Pain?
Your spine is at the center of a delicately balanced system that
controls all of your body's movements. Bones, muscles, ligaments,
tendons, and nerves all work together to balance the weight of your
body. Even minor damage to one component of your back's structure
can upset this fragile balance and make movement painful. It is
not surprising, then, that back pain is second only to headache
as the most common cause of pain, or that 8 out of 10 people will
have a problem with back pain at some time.
Back pain occurs when one or more nerves in the spinal column become
impinged, or pinched. This is commonly caused by a disc or bone
spur pushing into the canal that houses the spinal cord, the cauda
equina, and the nerve roots.
At birth, discs are comprised primarily of water, but they tend
to dry and shrink as a person ages, causing changes in the spinal
column. Further changes can occur when a disc ruptures or herniates
(protrudes) because of injury. Very often in response to these changes,
tissue around the spinal canal thickens, reducing the space in the
spinal canal. This narrowing is commonly called stenosis. Additionally,
when the facet joints degenerate, they become larger, form spurs,
and can pinch the nerve roots or even the spinal cord.
If you are unable to function at an acceptable level for your lifestyle,
or your neurological deficit is becoming progressively worse in
spite of conservative treatment, then surgery is often the recommended
treatment. In the vast majority of cases, modern spinal surgery
is extremely successful in alleviating pain and restoring mobility.
Orthopedic Spine Care of Long Island, PC—a highly skilled
and experienced orthopaedic practice—has helped hundreds of
patients like you achieve freedom from pain with spinal surgery.
There are a number of different surgical approaches to relieving
back pain. Orthopedic Spine Care of Long Island, PC has determined
which one is best for you based on your specific condition. The
following is a general description of some of the most commonly
performed procedures:
• Discectomy—the removal of all or
part of the offending disc
• Decompression—the removal of bone
spurs
• Corpectomy—the removal of a vertebra
• Fusion—the joining of discs to prevent
motion in the affected area
Spinal surgery, as with any major surgery, is not without risks.
Orthopaedic surgeons at the Orthopedic Spine Care of Long Island,
PC will discuss with you possible complications of surgery and will
tell you how you can help reduce your risks both before and after
surgery.
Understanding Spinal Anatomy
Your spine is a strong and flexible bony structure, made up of five
sections from the neck to the tailbone, consisting of 33 bones or
vertebrae.
1. Cervical spine (neck)
2. Thoracic spine (upper back)
3. Lumbar spine (lower back)
4. Sacrum
5. Coccyx (tailbone)
In the cervical, thoracic, and lumbar areas, cushion-like discs
separate the vertebrae, giving the spine the ability to bend and
turn. There are five vertebrae in the sacrum, but they are fused
naturally and do not have discs to separate them. The coccyx has
four smaller vertebrae that also are fused.
The Cervical Spine
The cervical spine (neck) consists of seven vertebrae numbered C1
through C7 from top to bottom. Each of the top two vertebrae has
a unique design. C1 is a two-tiered ring that is attached to the
skull. C2 has a protrusion that acts as a post around which C1 rotates.
C1 and C2 are primarily responsible for the motion of the head.
Each of the remaining vertebrae in the cervical, thoracic, and lumbar
regions has a pair of facet joints that connect to muscles and ligaments
to keep the vertebra in place, as well as a disc, which cushions
the spine and allows it to move.
The Thoracic Spine
The thoracic spine (upper back) consists of 12 vertebrae that are
attached to the ribcage. Very little motion occurs in this region
and problems in this area are relatively uncommon.
The Lumbar Spine
The lumbar spine has five vertebrae. This region endures a lot of
stress, especially when you bend, and is a common source of back
pain.
The Spinal Cord
The spinal cord runs from the brain through the cervical and thoracic
spine, where the nerve roots come off the cord to form the cauda
equina, or “horse’s tail.” At each level of vertebra,
a nerve root exits on each side of the spine to the right and the
left.
In the cervical spine, the nerve root is labeled according to the
lower segment that it runs between; in the lumbar spine, the nerve
root is named after the
upper segment that it runs between. That means that the C5 nerve
root runs between C5 and C4, and the L4 nerve root runs between
L4 and L5.
