A compression fracture of the back occurs when the bones of your spine (vertebrae) collapse. Compression fractures can cause your vertebrae to collapse, leading to poor posture, pain, loss of height, and a variety of other symptoms.
Other possible causes of compression fractures of the back include:
- physical trauma to your back
- a tumor that either originates in your spine or spreads to your spinal area (relatively rare)
The following people are at a high risk for a compression fracture of the back:
- women, especially those who have gone through menopause
- older men, particularly those over 60
- people with a calcium deficiency
Compression fractures caused by back injuries can be very painful. It may feel as though someone is stabbing a knife into your back. Fractures resulting from osteoporosis may cause you more pain when you are standing than when you are lying down. These fractures may also cause you to stoop over, develop a hump on your back (kyphosis), and loose up to six inches in height as your vertebrae compress.
The following symptoms are rare, but they are caused by pressure on your spinal chord due to poor posture:
- numbness or tingling in your limbs or other areas of your body
- difficulty walking and moving around
Your doctor will first examine you to see if your spine is curved or if you have developed a hump on your back. The doctor will then use a CT scan, an MRI, an X-ray, and/or a bone density test to check for osteoporosis and to diagnose compression fractures.
Tumors that may be responsible for a compression fracture can show up in diagnostic imaging tests, as can traumatic injuries to your back.
If the underlying cause of you compression fractures is osteoporosis, your doctor may recommend:
- pain medications
- bed rest to help your body heal
- physical therapy to help strengthen your core muscles and spinal support muscles
- a back brace, which can help support your spine
- calcium supplements to prevent additional bone problems and future compression fractures
If a tumor has caused your compression fracture, more invasive treatments may be used, including:
- surgery to remove sections of bone or tissue
- lengthening your spine by injecting a special kind of cement (vertebroplasty) into the space between your vertebrae
If your fractures are caused by a back injury, your surgeon may need to fuse some of your vertebrae together to relieve pain and pressure on your nerves.
Many patients with osteoporosis are able to live without high levels of back pain if they rest and take pain medication as needed. It isn’t possible to reverse bone damage from osteoporosis, but taking calcium supplements, not smoking, and taking medication to strengthen your bones can help protect against future breaks.
If an injury caused your compression fracture, recovery can take eight to ten weeks or longer. You may need to wear a back brace and get plenty of bed rest. If a tumor caused your fracture, the underlying cause of the tumor (lung cancer, for example) must be treated and the tumor removed. Your prognosis will depend on the type of tumor that caused your condition.
