Spinal Compression Fracture: Causes and Treatment

What You Need to Know About Spinal Compression Fractures

A spinal compression fracture happens when one or more vertebrae in the spine collapse or crack under pressure. Picture a building block that slowly crumbles under too much weight. That's essentially what occurs in the vertebral body. These fractures most often happen in the middle and lower back. They can occur suddenly following an injury or develop gradually as bones weaken. Many people don't even realize they have one until the pain becomes severe or their posture changes noticeably. The good news? Understanding the causes and treatment options can help patients make informed decisions about their care.

Common Symptoms and Warning Signs

The most obvious symptom is sudden, sharp back pain that gets worse when standing or walking. Some people describe it as a stabbing sensation that appears out of nowhere. Others notice a gradual ache that builds over weeks.
Height loss is another telltale sign. Losing an inch or more over time often indicates that multiple compression fractures have occurred. Patients may also notice their clothes fitting differently or that bending forward becomes increasingly difficult.

The Impact on Spinal Alignment and Kyphosis

When vertebrae collapse, the spine curves forward abnormally. This condition, called kyphosis, produces the hunched posture often associated with aging. Vertebral compression fractures are common as you age or happen due to osteoporosis, causing the bone to collapse.
Kyphosis does more than affect appearance. It can compress internal organs, making breathing harder and digestion more difficult. The forward curve also shifts the body's center of gravity, increasing fall risk and potentially increasing fracture risk.

Primary Causes and Risk Factors

Understanding why these fractures happen is the first step toward prevention. Three main categories account for nearly all cases.

Osteoporosis and Bone Density Loss

Osteoporosis stands as the number one cause of spinal compression fractures. This condition weakens bones until everyday activities like sneezing, coughing, or bending over can cause a vertebra to crack. An estimated 20% of women over 50 have at least one vertebral compression fracture.
Women face a higher risk due to hormonal changes after menopause that accelerate bone loss. Men aren't immune, though their fractures typically occur about a decade later than women's.

Traumatic Injuries and High-Impact Accidents

Car crashes, falls from heights, and sports injuries can cause compression fractures even in healthy bones. The force overwhelms the vertebra's structural capacity, causing immediate collapse. These traumatic fractures often occur alongside other injuries and require emergency care.
Young, active individuals with strong bones can experience these fractures when extreme force is applied. The treatment approach differs significantly from that of osteoporotic fractures because the underlying bone quality remains good.

Pathological Fractures from Spinal Tumors

Cancer that spreads to the spine weakens vertebrae from the inside. Tumors eat away at bone tissue, creating hollow spaces that can't support normal loads. These pathological fractures require treatment of both the fracture itself and the underlying cancer.
Multiple myeloma, breast cancer, lung cancer, and prostate cancer most commonly spread to the spine. Patients with these diagnoses should report any new back pain immediately.

Diagnostic Procedures and Imaging

Physicians typically begin with a physical examination and medical history. They'll ask about pain location, when it started, and what makes it better or worse. Pressing on the spine helps identify tender areas.
X-rays confirm most compression fractures by showing vertebral height loss or wedge-shaped deformities. MRI scans provide more detail, revealing whether the fracture is new or old and whether soft tissues are affected. CT scans offer the clearest view of bone structure when surgical planning is needed.
Bone density testing through DEXA scans measures osteoporosis severity. This information guides both treatment decisions and prevention strategies. Doctronic.ai can help patients understand their test results and discuss next steps with qualified medical professionals.

Conservative Non-Surgical Treatments

Most compression fractures heal without surgery. The body can repair minor damage when provided with appropriate support and time.

Pain Management and Medication

Over-the-counter pain relievers like acetaminophen and ibuprofen work for mild cases. More potent prescription medications may be required initially. Physicians often recommend short periods of rest, although prolonged bed rest slows healing and weakens muscles.
Nerve block injections can provide relief when oral medications aren't enough. These target specific pain generators near the fracture site.

Back Bracing and Physical Therapy

A rigid back brace limits spinal movement, allowing the fracture to heal while preventing further collapse. Most patients wear braces for 6 to 10 weeks. The brace should fit properly and be worn as directed for best results.
Physical therapy begins once acute pain subsides. Therapists teach exercises that strengthen core muscles without stressing the injured vertebra. Proper body mechanics training helps patients move safely during daily activities.

Surgical Interventions and Minimally Invasive Procedures

Surgery becomes necessary when conservative treatment fails or when fractures cause severe deformity. Modern techniques allow most procedures to be performed through tiny incisions.

Vertebroplasty and Kyphoplasty

Both procedures involve injecting bone cement into the fractured vertebra to stabilize it. Vertebroplasty injects cement directly into the collapsed bone. Kyphoplasty first inflates a balloon to restore some vertebral height before cement injection.
Kyphoplasty may offer better mobility and correction of vertebral body deformities compared to vertebroplasty. Both procedures typically take about one to two hours and allow many patients to go home the same day.

Spinal Fusion for Severe Instability

When fractures cause significant instability or nerve compression, spinal fusion may be required. This surgery permanently connects two or more vertebrae using metal hardware and bone grafts. Recovery is longer than with minimally invasive options, but fusion provides durable stability in severe cases.

Prevention Strategies and Long-Term Bone Health

Preventing compression fractures starts with building and maintaining strong bones. Weight-bearing exercise like walking, dancing, and climbing stairs stimulates bone growth. Resistance training strengthens muscles that support the spine.
Calcium and vitamin D intake should meet daily recommendations. Most adults need 1,000 to 1,200 milligrams of calcium and 800 to 1,000 IU of vitamin D daily. Food sources are preferable, but supplements can fill gaps.
Fall prevention matters enormously for those at risk. Remove tripping hazards at home, install grab bars in bathrooms, and ensure adequate lighting. Regular vision checks help identify problems that increase fall risk.
Medications that slow bone loss or build new bone are available for those with osteoporosis. Bisphosphonates, denosumab, and other treatments can significantly reduce fracture risk when taken as prescribed.
