Compression fractures of the back are broken vertebrae. Vertebrae are the bones of the spine.
Osteoporosis is the most common cause of this type of fracture. Osteoporosis is a disease in which bones become fragile. In most cases, bone loses calcium and other minerals with age. Other causes may include:
Having many fractures of the vertebrae can lead to kyphosis. This is a hump-like curvature of the spine.
Compression fractures can occur suddenly. This can cause severe back pain.
Compression fractures due to osteoporosis may cause no symptoms at first. Often, they are discovered when x-rays of the spine are done for other reasons. Over time, the following symptoms may occur:
Pressure on the spinal cord from hunched over posture can, in rare cases, cause:
Your health care provider will perform a physical exam. This may show:
A spine x-ray may show at least 1 compressed vertebra that is shorter than the other vertebrae.
Other tests that may be done:
Most compression fractures are seen in older people with osteoporosis. These fractures often do not cause injury to the spinal cord. The condition is usually treated with medicines and calcium supplements to prevent further fractures.
Pain may be treated with:
Other treatments may include:
Surgery may be done if you have severe and disabling pain for more than 2 months that does not get better with other treatments. Surgery can include:
Other surgery may be done to remove bone if the fracture is due to a tumor.
After surgery you may need:
Most compression fractures due to injury heal in 8 to 10 weeks with rest, wearing of a brace, and pain medicines. However, recovery can take much longer if surgery was done.
Fractures due to osteoporosis often become less painful with rest and pain medicines. Some fractures, though, can lead to long-term (chronic) pain and disability.
Medicines to treat osteoporosis can help prevent future fractures. However, medicines cannot reverse damage that has already occurred.
For compression fractures caused by tumors, the outcome depends on the type of tumor involved. Tumors that involve the spine include:
Complications may include:
Call your provider if:
Taking steps to prevent and treat osteoporosis is the most effective way to prevent compression or insufficiency fractures. Getting regular load-bearing exercise (such as walking) can help you avoid bone loss.
