Overview
A vertebral compression fracture is a break in one of the bones (vertebrae) of the spine where the bone collapses, usually reducing its height. It most often affects the thoracic or lumbar spine and can cause pain because the injured bone and nearby tissues become irritated during movement. Depending on the cause and severity, it may lead to reduced mobility and sometimes body posture changes such as a gradual forward curve. When the fracture is due to osteoporosis, it can signal that bone strength is significantly reduced.
Symptoms
Pain is often felt in the mid-back or low back and may worsen with standing, walking, bending, or twisting, especially soon after the injury. Some people notice stiffness, muscle spasm, and limited ability to sit or lift objects. If the fracture is related to nerve irritation, symptoms may include pain that shoots into the leg or numbness/tingling, though many compression fractures do not directly injure nerves. In more severe or multiple fractures, posture can change and breathing may feel less comfortable due to reduced chest wall movement.
Causes
Vertebral compression fractures most commonly occur after trauma such as a fall, a sports injury, or a car accident. In older adults or people with low bone density, even minor stress-like lifting, a sudden twist, or coughing-can cause the vertebra to collapse. The typical mechanism is loss of structural strength or direct compressive force that leads to microfracture and then collapse of the vertebral body. Osteoporosis is the leading underlying cause in many nontraumatic cases.
Risk Factors
Risk is higher with osteoporosis or osteopenia, which makes vertebrae more likely to fracture under relatively small forces. Age, prior fractures, and long-term steroid use (such as prednisone) increase the chance of bone weakening. Smoking, excessive alcohol intake, low body weight, and certain medical conditions that affect bone metabolism (such as some endocrine disorders) can further raise risk. A history of cancer can also increase risk because bone can weaken or be affected by metastases.
Prevention
Preventing a first or repeat compression fracture focuses on protecting bone and reducing fall risk. Regular weight-bearing and resistance exercise, adequate calcium and vitamin D intake, and smoking cessation can support bone strength. If osteoporosis is diagnosed, taking prescribed osteoporosis medications and attending follow-up bone health care can reduce future fractures. Using safe movement techniques, improving balance, and ensuring good home lighting and fall-proofing can lower the risk of traumatic injury.
How the Diagnosis Is Evaluated
A clinician typically starts with a history of how the pain began, including any fall or injury, and whether the pain is sudden or progressively worsening. The physical exam checks spine tenderness, range of motion, posture, gait, and any signs of nerve involvement such as weakness or abnormal sensation. Imaging is used to confirm the diagnosis, most often starting with X-rays, which can show vertebral height loss and fracture patterns. MRI is commonly used when the fracture is suspected but X-rays are unclear, when pain is severe, or when there are neurologic symptoms or concern for other causes like infection or tumor.
Nonsurgical Treatment Options
Most vertebral compression fractures are treated conservatively to reduce pain and allow healing. This usually includes short-term pain control with acetaminophen and/or nonsteroidal anti-inflammatory drugs if appropriate, along with activity modification and gradual return to movement. Bracing (such as a thoracolumbar brace) may be used for short periods to limit painful motion and improve comfort. Physical therapy focuses on gentle mobility, safe strengthening, posture training, and fall-prevention strategies. If the fracture is due to osteoporosis, clinicians may also recommend osteoporosis treatment to improve bone strength and reduce the risk of future fractures. In selected cases with persistent, severe pain despite conservative care, minimally invasive options like vertebroplasty or kyphoplasty may be considered; these are typically discussed after imaging confirms an appropriate fracture pattern and timing.
When to Seek Medical Attention
Seek prompt medical attention if you have new back pain after a fall, especially if the pain is severe, worsening, or limits walking. Get urgent care right away if you develop numbness, tingling, weakness, trouble walking, or any bowel or bladder changes. Also seek urgent evaluation for fever, unexplained weight loss, severe night pain, or pain that does not improve at all after the initial healing period. If you cannot bear weight, have rapidly progressive deformity, or experience sudden escalation of symptoms, contact a clinician immediately.
Frequently Asked Questions
Answer What does a vertebral compression fracture feel like?
Answer Many compression fractures improve over weeks with conservative care, but the timeline varies depending on the fracture cause and severity.
Answer Most people are treated without surgery, and additional procedures are usually reserved for persistent, severe pain or specific imaging findings.
Next Steps
If you suspect a vertebral compression fracture, arrange an evaluation soon-especially if pain started after a fall or is severe and limiting. Ask whether imaging is needed and whether your symptoms suggest nerve involvement or a nontraumatic cause like osteoporosis. In the meantime, consider gentle activity within comfort and avoid heavy lifting or twisting until you're assessed.
