Lumbar vertebral fracture

A vertebral fracture is a break or collapse of a bone in the spine. It primarily affects individuals with bones weakened by osteoporosis or those who have experienced significant trauma. This injury leads to acute back pain, changes in posture, and limitations in daily activities. It requires a thorough medical evaluation and structured rehabilitation, including physiotherapy, to manage pain, restore mobility through safe, progressive exercises, strengthen supporting muscles, and implement strategies to prevent falls. To understand how vertebral fractures differ from other back problems, please consult our complete guide to back pain.

What is a vertebral compression fracture?

A vertebral compression fracture occurs when a bone in the spine crushes or collapses, losing more than 15-20% of its normal height. This type of fracture primarily affects the thoracolumbar junction (T11-L2) in individuals with bones weakened by osteoporosis.¹

The spine is made up of bones called vertebrae. Each vertebra has a hard outer shell (cortical bone) and a spongy interior (trabecular bone). The spongy bone provides strength to the vertebra while keeping it lightweight. When too much pressure is applied, this interior collapses. This typically happens in the front part of the vertebra during bending movements.²

The thoracolumbar junction (T11-L2) experiences the most fractures because it's a transition zone between the rigid thoracic spine and the more mobile lumbar spine. This area undergoes significant mechanical stress during daily activities.⁵ The middle of the thoracic spine (T6-T8) also shows a high risk in individuals with lumbar osteoarthritis and osteoporosis. Multiple fractures can lead to an excessive forward curvature called kyphosis (a rounded back) and a gradual loss of height.

What causes spinal fractures?

Osteoporosis is the cause of most vertebral fractures, accounting for approximately 700,000 fractures annually in the United States. Postmenopausal women are 2 to 3 times more at risk than men, and this risk significantly increases after age 60.^7,8

The main causes include:

Osteoporosis (fragility fractures): A healthy young adult's bones can withstand 6,000-8,000 Newtons of force. Advanced osteoporosis reduces this resistance to less than 2,000 Newtons.⁹ Fractures can occur during everyday activities like coughing, sneezing, or bending forward. High-energy trauma: Falls from heights, car accidents, and sports injuries create enough force to fracture even healthy vertebrae in young adults.¹⁰ Pathological conditions: Cancer can spread to the spine (metastases), creating areas of bone destruction vulnerable to fractures. Breast, lung, prostate, and kidney cancers frequently spread to the spine.¹¹ Repetitive loading: Stress fractures affect certain athletes involved in gymnastics, rowing, or weight training.¹⁴

Category	Risk factors
Age and sex	Advanced age (especially over 60), female sex (2-3x higher risk)
Medical history	Previous vertebral fracture (5x higher risk), family history of osteoporosis
Medications	Prolonged use of corticosteroids (prednisone, cortisone)
Lifestyle	Smoking, excessive alcohol consumption, sedentary lifestyle, low body weight
Nutrition	Vitamin D deficiency, insufficient calcium intake

The good news? Most vertebral fractures heal well with proper care. Your body has a remarkable ability to repair bone.

What are the symptoms of a vertebral fracture?

Vertebral fractures cause sudden and intense back pain (rated 7-10 out of 10) at the fracture site. This pain is worsened by movement and relieved by resting in a lying position. Chronic symptoms include a gradual loss of height and a hunched posture.^15,16

Acute symptoms: Pain peaks within a few hours after the fracture. Patients describe sharp, throbbing, or crushing pain. They can often identify the exact moment of injury. Worsening pain: Bending forward, getting up from a chair, and rolling in bed increase pain. Lying on your back with proper support partially relieves it. Chronic symptoms: Each fracture can reduce total height by 1-2 centimeters.¹⁷ Multiple fractures lead to a cumulative loss of height and progressive thoracic kyphosis (giving the appearance of a "dowager's hump").¹⁸ Severe kyphosis reduces the volume of the rib cage, potentially causing shortness of breath during exertion, with an approximate 9% reduction in lung volume for each thoracic fracture.²⁰ Silent Fractures: Approximately one-third of vertebral fractures remain clinically silent, discovered incidentally during imaging for other reasons.²²

Rest assured: even if the pain is intense initially, it generally lessens significantly within the first few weeks. It's normal to feel limited at first. With time and the right exercises, you will regain your mobility.

How are spinal fractures diagnosed?

Diagnosis involves a combination of X-rays to show vertebral height loss, an MRI to distinguish between acute and chronic fractures, and a DEXA test to evaluate underlying osteoporosis. The TLICS classification helps guide decisions for either conservative or surgical treatment.²³

X-rays: Lateral views show the loss of vertebral body height and fracture lines. A loss of height exceeding 15-20% indicates a fracture. Genant Classification: Grade 1 (mild): 20-25% height loss. Grade 2 (moderate): 25-40%. Grade 3 (severe): over 40%.²⁴ MRI (Magnetic Resonance Imaging): MRI definitively identifies acute fractures due to bone marrow edema patterns visible for 6-12 weeks post-injury.²⁵ It also differentiates benign osteoporotic fractures from pathological fractures caused by cancer.²⁶ DEXA Test (Bone Density): T-scores between -1.0 and -2.5 indicate osteopenia (low bone mass). T-scores below -2.5 define osteoporosis. Each standard deviation decrease in bone density approximately doubles the risk of fracture.^27,28

Which imaging technique best shows spinal fractures?

MRI proves superior for detecting acute fractures, determining the age of a fracture, and identifying pathological fractures. This is thanks to its ability to visualize soft tissues, which is not possible with X-rays or CT scans.²⁹

How are fractures classified for treatment?

The TLICS (Thoracolumbar Injury Classification and Severity) classification system assesses the fracture's shape, ligament integrity, and neurological status. Scores below 4 points typically suggest conservative management, whereas scores above 4 indicate a potential benefit from surgery.³⁰

How does physical therapy help with recovery from spinal fractures?

Physiotherapy guides recovery through three distinct phases: acute pain management (0-4 weeks), progressive mobilization (4-8 weeks), and strengthening (8-16 weeks). This includes safe exercises, education on body mechanics, and strategies for fall prevention.

To learn more about how physiotherapy effectively treats back pain, please visit our page on services for the back region.

Phase	Timeline	Goals and interventions
Acute	0-4 weeks	Pain management, positioning (pillows under knees), body mechanics, transfer techniques
Subacute	4-8 weeks	Progressive walking, gentle range of motion exercises, beginning extension exercises
Consolidation	8-16 weeks	Progressive strengthening, resistance training, balance training, fall prevention

Fall prevention programs reduce the rate of falls by approximately 25% in older adults.³⁸

You are not alone in this journey. Our physiotherapists will support you every step of the way, adjusting exercises to your comfort level.

How long does it take for spinal fractures to heal?

Vertebral fractures typically heal within 12-16 weeks. Acute pain significantly lessens after 4-6 weeks. Bone healing progresses through inflammatory, reparative, and remodeling phases over 3-12 months.^39,40

Pain Trajectory: Severe acute pain is most prominent during the first 2-4 weeks, then gradually decreases. Most patients experience a substantial reduction by 6-8 weeks.⁴¹ Approximately 30% of patients report persistent pain beyond 12 months.⁴² Fracture Cascade Risk: Patients with a vertebral fracture face an approximately 5 times higher risk of additional vertebral fractures and a 2 times higher risk of hip fractures.⁴⁵

Everyone heals at their own pace. If your recovery takes longer than expected, don't be discouraged. Your physical therapist will adjust your program according to your individual progress.

What exercises are safe after a spinal fracture?

Safe exercises include walking with good posture, isometric core strengthening, spinal extension exercises, and balance training. Initially, avoid bending forward and twisting under load.

Walk: Exercise is safest and most beneficial early on. Maintain an upright posture and avoid leaning forward.⁴⁶ Start with 5-10 minutes, then gradually increase to 30 minutes daily by 6-8 weeks. Isometric Exercises: Muscle contraction without joint movement, safe during acute phases. Abdominal bracing (gentle contraction of the transverse abdominis) and gluteal squeezes are particularly recommended.⁴⁷ Perform holds for 5-10 seconds, repeat 10 times. Extension Exercises: Lying face down (prone position) for 10-15 minutes daily provides gentle passive extension.⁴⁸ Active exercises include prone lifts (cobra pose), wall angels, and chin tucks. Progressive Resistance Training: Starts approximately 8-12 weeks post-fracture.⁴⁹ Progress from body weight to resistance bands to light free weights. Balance Training: Single-leg standing, tandem walking (heel-to-toe), weight-shifting exercises, and gentle tai chi movements.⁵¹ Begin with stable support (hold onto a counter), then progress to unsupported challenges. To Avoid Initially: Forward bending under load, twisting under load, high-impact activities.

How can future spinal fractures be prevented?

Prevention combines osteoporosis treatment (bisphosphonates reduce risk by 50-70%), calcium (1200mg) and vitamin D (800-1000 IU) supplementation, regular weight-bearing exercise, and fall prevention strategies.⁵³

Strategy	Recommendations
Medications	Bisphosphonates (alendronate, risedronate), denosumab, anabolic agents (teriparatide)
Supplements	Calcium 1200mg/day, vitamin D 800-1000 IU/day, magnesium
Exercise	Daily weight-bearing activities (walking, stairs), strength training 2-3 times/week
Fall prevention	Home safety, vision correction, medication review, balance exercises
Lifestyle	Smoking cessation, limit alcohol, maintain healthy weight, adequate protein intake

Osteoporosis Medications: Bisphosphonates (alendronate, risedronate) reduce the risk of vertebral fracture by 50-70%.⁵³ Anabolic agents (teriparatide, romosozumab) show an even greater reduction of 65-85% in severe cases.⁵⁴ Exercise for Bone Health: Weight-bearing activities (walking, climbing stairs, dancing) stimulate bone formation.⁵⁷ Resistance training 2-3 times per week with moderate to high intensity improves bone density.⁵⁸ Fall prevention: Home safety assessments eliminate hazards (loose rugs, poor lighting). Vision correction and medication review also reduce the risk of falls.⁵⁹

When are procedures such as vertebroplasty considered?

Vertebroplasty is considered for painful fractures that do not respond to 4-6 weeks of conservative treatment. This injection of bone cement offers potential relief, but controlled studies show mixed results.⁶⁵

Vertebroplasty: Percutaneous injection of bone cement (PMMA) into the fractured vertebral body under fluoroscopic guidance to stabilize the fracture.⁶³ Kyphoplasty: Adds an initial step of inflating a balloon inside the vertebral body to attempt to restore height before cement injection.⁶⁴ Effectiveness: Initial studies suggested dramatic relief in 75-90% of patients.⁶⁷ However, two placebo-controlled trials published in 2009 showed no significant benefit compared to a sham procedure.⁶⁸ Subsequent studies suggest modest benefits in carefully selected patients.⁶⁹

The decision requires an individualized assessment, weighing potential benefits against risks, considering pain severity, fracture characteristics, and response to conservative treatment.

What are the long-term effects of spinal fractures?

Long-term effects include chronic pain (30% of patients beyond one year), progressive deformity with kyphosis and height loss, reduced lung function, and a 5 times higher risk of future vertebral fractures.^72,77

Chronic pain: Persists beyond expected healing times in approximately 30% of patients. Management approaches include continued exercise, postural training, and manual therapy.⁷² Spinal DeformityProgressive thoracic kyphosis shifts the center of gravity forward, requiring compensatory postural adjustments and increased muscle effort.⁷³ Reduced lung capacityApproximately a 9% reduction in vital capacity for each thoracic vertebral fracture.⁷⁵ Fracture cascadePatients face an approximately 5 times higher risk of subsequent vertebral fractures and 2 times higher risk of hip fracture. The highest risk period occurs within the first year following the initial fracture, highlighting the importance of immediate aggressive osteoporosis treatment.^77,78

Patients receiving coordinated multidisciplinary care (medical treatment, physiotherapy, nutritional optimization) demonstrate superior outcomes.⁸¹
