A spinal compression fracture happens when one of the vertebrae — the small bones that make up the spine — collapses or breaks. It’s most often seen in older adults with osteoporosis, but it can also happen in younger people after trauma, heavy lifting, or from conditions that weaken bone. So what is a spinal compression fracture, and how do we manage it?

What is a spinal compression fracture?

The vertebrae are shaped like stacked blocks. When a bone is weakened or subjected to excessive force, one or more vertebrae can be compressed or collapse. This causes pain, loss of height, and sometimes a spinal deformity. Compression fractures are most common in the mid-to-lower thoracic spine (between the shoulder blades and the lower back), though they also occur in the lower back.

Symptoms of a spinal compression fracture

Symptoms range from mild to severe. Common features include:

  • Sudden back pain after bending, lifting, or minor trauma
  • Pain that worsens on standing or walking and eases when lying down; coughing or sneezing can aggravate it
  • Tenderness over the affected vertebra
  • Loss of height, in long-standing cases
  • Numbness or tingling, in severe cases where the fracture presses on a nerve

Many people initially mistake the pain for a simple muscle strain, which can delay diagnosis.

When a spinal compression fracture needs prompt attention

See a doctor if you’re older — particularly postmenopausal — and develop sudden back pain after a minor strain or fall, as this can be an osteoporotic compression fracture. Seek urgent assessment for back pain with leg weakness, numbness around the back passage, or loss of bladder or bowel control, which can signal pressure on the spinal cord or nerves. It’s also important to exclude an underlying cause such as cancer or myeloma, especially with unexplained weight loss, night pain, or a history of cancer.

Causes and risk factors

The commonest cause is osteoporosis, which weakens the bone. Other causes include:

  • Trauma, such as a fall or road accident
  • Prolonged corticosteroid use
  • Metabolic bone diseases
  • High-impact sport or weightlifting, in rare cases

How is a spinal compression fracture diagnosed?

A careful assessment confirms the fracture and identifies the underlying cause:

  • X-rays — the first-line test, showing loss of vertebral height (more than about 4 mm) or a wedge-shaped deformity
  • MRI — dates the fracture (new vs old), rules out malignancy or infection, and shows whether the spinal cord or nerves are affected
  • CT — assesses fracture stability and helps plan treatment
  • Bone-density (DEXA) scan — essential for assessing osteoporosis in postmenopausal women and older men
  • Blood tests — for metabolic bone disease or malignancy (including a myeloma screen: blood count, inflammatory markers, calcium, vitamin D, PTH and thyroid, kidney function, bone profile, protein electrophoresis, and testosterone in men)

Spinal compression fracture treatment

Treatment depends on the severity, the symptoms, and the underlying cause.

Conservative treatment

Most spinal compression fracture treatment is managed without surgery:

  • Rest and activity modification, with a return to gentle activity almost immediately, within comfort
  • Pain relief with paracetamol or anti-inflammatories
  • A spinal brace can be offered for support and pain, though the evidence is limited
  • Physiotherapy to strengthen the core and back muscles once the pain settles
  • Osteoporosis management — calcium, vitamin D, and bisphosphonates, which reduce acute fracture pain (as an IV infusion) and help prevent further fractures
  • Intranasal calcitonin (200 units daily) may reduce pain and improve mobility in the first four weeks.

Interventional options

Considered only if the pain is severe or persistent despite a brace, painkillers, bone medication, and physiotherapy for at least three weeks:

  • Vertebroplasty — injecting bone cement into the fractured vertebra. Notably, two high-quality studies found no benefit over a placebo procedure, so it’s used selectively.
  • Kyphoplasty — similar, but a small balloon first restores some height before the cement. Results are generally better than vertebroplasty, though the risks are higher.

Surgery

Rarely needed, but indicated for unstable fractures or those compressing the spinal cord.

Recovery and rehabilitation

Healing usually takes 8–12 weeks, though it varies. Early physiotherapy — posture, flexibility, and strengthening the muscles on either side of the spine — helps prevent further injury and maintain mobility. Weight-bearing exercise, fall prevention, and osteoporosis management are key to reducing the risk of another fracture.

Frequently asked questions about a spinal compression fracture

How serious is a compression fracture of the spine?

It ranges from mild to severe. Most cause pain without threatening the spinal cord, but multiple fractures can lead to deformity, chronic pain, or even restricted breathing. Fractures caused by cancer such as multiple myeloma or significant trauma can be more serious and need urgent management — which is why the cause is always investigated.

How can you strengthen the spine after a compression fracture?

Rehabilitation is essential. Physiotherapy focuses on gentle core and back extensor strengthening, posture correction, and balance training, while weight-bearing exercises such as walking help maintain bone density. Adequate calcium and vitamin D, plus osteoporosis medication where needed, strengthen the bone and help prevent further fractures.

How long does a spinal compression fracture take to heal?

Most heal within 8–12 weeks with conservative treatment. The pain usually improves within a few weeks, though full recovery can take longer in people with osteoporosis. Early, guided movement is key to regaining function.

Does a compression fracture always mean osteoporosis?

Not always, but it’s the commonest cause — so osteoporosis should be assessed (with a DEXA scan) in older adults. In younger people, or where there are warning signs, other causes such as trauma, steroid use, or (rarely) cancer such as multiple myeloma are considered. Finding and treating the underlying cause is part of preventing the next fracture.

Final word from Sport Doctor London about spinal compression fractures

Spinal compression fractures are common, especially in older adults with osteoporosis. Most heal with conservative treatment, but early diagnosis, proper bone-health management, and targeted rehabilitation are essential for a full recovery and to prevent recurrence. If you’re older and develop sudden back pain — particularly after a minor strain or injury — it’s important to be assessed to rule out a compression fracture.
