X-ray images of a person's spine to measure spinal
curvature. A curve or angle of the spine is measured in degrees and describes
how severe the curve is. (The angle is determined by the intersection of lines
projected from the top and bottom of the curve.) If the spine is straight,
there is no angle; this would be a 0-degree curve. If the spine is curved, the
angle can be measured. The larger the curve, the larger the angle or degree
measurement. For example, a 10-degree curve is considered a mild curve, and a
50-degree curve is considered a severe curve.
Many people have
some curve in their spine. In fact, spinal curves that are less than 10 degrees
are considered a normal variation of the spine. Curves that are greater than 10
degrees may be monitored (to see whether the curve is getting worse) or may
How do you know when that achy pain in your back is more than you can handle alone? Experts agree -- if your back pain is in conjunction with any of the following symptoms, skip the at-home remedies for in-office help.
There are several red flags that doctors look for when evaluating low back pain.
The purpose of these warning signs is to detect fractures, tumors, or infections of the spine. If you have any of these red flags along with back pain, see your doctor as soon as possible.
In addition to the severity of the curve, curves
are described by their direction and location.
Direction is based on which way the curve bends
away from the center of the body. For example, if the inner side of the curve
is to the right, it is called a right curve.
Location is determined
by the spinal bone at the center of the curve. The spine is divided into three
parts: neck region (cervical), chest area (thoracic), and lower back (lumbar).
A curve may be labeled according to the number of spinal bones involved. For
example, T5 to T12 means that the curve involves the 5th through the 12th chest
(thoracic) spinal bones.
