Spinal Injury- Fractures of Vertebrae

Osteoporosis and Spinal Fractures

As we get older, our bones thin and our bone strength decreases. Osteoporosis is a disease in which bones become very weak and more likely to break. It often develops unnoticed over many years, with no symptoms or discomfort until a bone breaks.

Fractures caused by osteoporosis most often occur in the spine. These spinal fractures — called vertebral compression fractures — occur in nearly 700,000 patients each year. They are almost twice as common as other fractures typically linked to osteoporosis, such as broken hips and wrists.

Not all vertebral compression fractures are due to osteoporosis. But when the disease is involved, a fracture is often a patient’s first sign of a weakened skeleton from osteoporosis. To learn more about osteoporosis


Your spine is made up of 24 bones, called vertebrae, that are stacked on top of one another. These bones connect to create a canal that protects the spinal cord. Other parts of your spine include:

Spinal cord and nerves. These “electrical cables” travel through the spinal canal carrying messages between your brain and muscles. Nerve roots branch out from the spinal cord through openings in the vertebrae.

Intervertebral disks. In between your vertebrae are flexible intervertebral disks. These flat, round disks are about a half-inch thick. They cushion the vertebrae, acting as shock absorbers when you walk or run.

Osteoporosis is a natural aging phenomenon; as we get older, our bones weaken. When the vertebrae in the spine weaken, they can narrow and become flatter. This can make elderly patients shorter and lead to a rounded back, a hump or a “bent forward look” to the spine.

Changes in the spine from the progression of osteoporosis

As osteoporosis progresses, the vertebrae weaken and become flatter. This can cause a severely rounded back (“dowager’s hump”).

The weakened vertebrae are at a high risk for fracture. A vertebral compression fracture occurs when too much pressure is placed on a weakened vertebra and the front of it cracks and loses height. Vertebral compression fractures are often the result of a fall, but people with osteoporosis can suffer a fracture even when doing everyday things, such as reaching, twisting, coughing, and sneezing.

A vertebral compression fracture

A vertebral compression fracture (arrow) has a wedged-shaped appearance. The front of the vertebra has cracked and shortened while the back remains intact.


A vertebral compression fracture causes back pain. The pain typically occurs near the break itself. Vertebral compression fractures most commonly occur near the waistline, as well as slightly above it (mid-chest) or below it (lower back).

The pain often gets worse with motion, particularly when you are changing positions. It is often relieved by rest or lying down. Coughing and sneezing can also make the pain increase. Although the pain may move to other areas of the body (for example, into the abdomen or down the legs), this is uncommon.

Doctor Examination

Physical Examination

Your doctor will talk with you about your general health and medical history and ask you to describe your symptoms. He or she will then perform a physical exam.

While you are standing, your doctor will examine the alignment, or straightness, of your spine and your posture. He or she will also push on certain places on your back to try and identify whether your pain is from an injury to the muscle or bones.

To make sure there is no injury to the spinal nerve roots, your doctor will conduct a neurologic examination—looking for loss of sensation, changes in reflexes, or muscle weakness.


Nonsurgical Treatment

Fortunately, most people who suffer a vertebral compression fracture get better within 3 months without specific treatment to repair the fracture. Simple measures, such as a short period of rest and limited use of pain medications, are often all that is required. In some cases, patients are instructed to wear a brace to restrict movement and allow the vertebral compression fracture to heal.

If your doctor has also diagnosed osteoporosis, you are at increased risk for additional vertebral compression fractures and other fractures, such as to the hip and wrist. Your doctor will address treatments for bone density loss during this time.

Surgical Treatment

If you have severe pain that does not respond to nonsurgical treatment, then surgery may be considered.

In the past, the only surgical options available to patients with vertebral compression fractures involved extensive procedures. Today, vertebral augmentation procedures offer a minimally invasive alternative.

The two types of vertebral augmentation methods available are kyphoplasty and vertebroplasty. The best candidates for these procedures are patients who suffer severe pain from recent vertebral compression fractures. If you are a candidate for kyphoplasty or vertebroplasty, your doctor will talk with you about which procedure may be better for you based on the type of vertebral compression fracture you have.

Kyphoplasty. In a kyphoplasty, a needle is inserted into the fractured vertebra using an x-ray for guidance. A small device called a balloon tamp is then inserted through the needle and into the fractured vertebra. The balloon tamp is inflated from within the vertebra, which restores the height and shape of the vertebral body. When the balloon tamp is removed, it leaves a cavity that is filled with a special bone cement that strengthens the vertebra.

Surgical Outcomes

Several reports have been published on the results of vertebral augmentation procedures. In two large studies, the benefit of vertebroplasty was found to be very short term. In contrast, studies indicate that kyphoplasty may increase function and decrease pain more quickly than nonoperative treatment.

The American Academy of Orthopaedic Surgeons has reviewed the current research on osteoporotic spinal compression fractures and developed a Clinical Practice Guideline that provides evidence-based information about vertebral augmentation procedures. For more information: .

Your doctor will discuss realistic expectations for recovery if vertebroplasty or kyphoplasty is recommended for you.
