The most common indication for
surgery in persons aged over 60 in the United States is Lumbar
Spinal Stenosis (LSS). Currently, it is estimated that as many as
400,000 Americans, most over the age of 60, may already be
suffering from the symptoms of lumbar spinal stenosis, and this
number is expected to grow as members of the baby boom generation
begin to reach their 60s over the next decade.
The majority of adults will experience pain
from a lumbar, cervical or thoracic spine problem in their
lifetime. Some estimates claim that 90 percent of the U.S.
population may have significant back pain at some point. Back and
neck problems are the most commonly occurring in medicine, and the
second most common neurological ailment in the United States,
second only to headaches. Americans spend at least $50 billion
each year on back and neck pain treatment, the most common cause
of job-related disability and a leading contributor to missed
work.

Acute back pain generally lasts from a few
days to a few weeks. Most acute back pain is the result of an
injury to the lower back or from a disorder such as arthritis.
Acute pain may be caused by a sports injury, everyday tasks, or a
sudden jolt such as a car accident. Symptoms may range from muscle
ache to shooting pain, limited flexibility or range of motion, or
an inability to stand straight.
When back pain occurs repeatedly, it is
known as recurrent back pain. And back pain lasting more than
three months and that doesn't improve within three to four weeks
of medication, is considered as chronic back pain. There are
approximately 5 million people in the U.S. currently suffering
with chronic back pain.
Chronic pain caused by spine problems can
seem very complex, since often the severity of the pain is not a
true indicator of the severity of the problem. There are nearly
100 different symptoms that can be attributed to problems
originating in the spine. The most common, and potentially the
most disabling, spine problem is stenosis of the lumbar canal. In
most cases, stenosis of the lumbar canal can be attributed to
acquired degenerative or arthritic changes in the intervertebral
discs, ligaments and facet joint surrounding the lumbar canal.
