What is a Spinal Fracture?
A "broken back" or spinal fracture happens when the structural integrity of a vertebra is compromised. Depending on how the bone breaks, a fracture can be stable (the spine remains aligned and can support weight) or unstable (the spine cannot carry weight, risking severe damage to the spinal cord and nerves).
While limb fractures are typically casted, spinal fractures are managed differently. Treatment focuses heavily on maintaining spinal stability and preventing neurological damage while the bone heals naturally.
Symptoms & Warning Signs
Symptoms of a spinal fracture vary widely based on the severity and location of the break.
Intense pain at the site of the fracture (often in the mid or lower back) that significantly worsens with movement, standing, or walking.
If bone fragments press against nerves or the spinal cord, you may experience numbness, tingling, or weakness in your arms or legs.
Severe weakness, paralysis in any part of the body, or a sudden loss of bladder or bowel control following a fall or injury are medical emergencies requiring immediate surgical evaluation.
Causes & Risk Factors
Spinal fractures are generally categorized into two main causes based on the patient's age and bone health:
The primary cause in younger, healthy individuals. This includes high-impact events like severe car accidents, major falls from a height, or sports injuries.
The leading cause of fractures in adults over 50. Osteoporosis causes bones to become porous and brittle. In severe cases, minor actions like twisting, bending to lift an object, or even a strong cough can cause a vertebra to collapse.
Types of Spinal Fractures
How the bone breaks dictates the treatment plan. The two most common forms are:
- 1
Compression Fractures: Common in osteoporosis. The front (anterior) part of the vertebra collapses under pressure, causing the bone to take on a "wedge" shape. These are usually stable fractures.
- 2
Burst Fractures: Usually caused by severe trauma. The vertebra is crushed in multiple directions, and bone fragments may spread out (burst) into the spinal canal, threatening the spinal cord. These are often highly unstable.
Treatment Options
Conservative (Non-Surgical) Treatment
Used for stable fractures where the spinal cord is not at risk:
- Pain Management: Medications to manage acute pain while the bone begins to knit together.
- Rest & Modification: A short period of rest followed by careful, modified activity.
- Bracing: Wearing a rigid back brace (like a TLSO) for 6 to 12 weeks to immobilize the spine and reduce pressure on the fractured bone.
Surgical Treatment
Surgery is required for unstable fractures, burst fractures, or when there is neurological damage.
For severe trauma, surgeons use metal screws and rods to stabilize the spine and remove any bone fragments pressing on the spinal cord.
For osteoporotic compression fractures, bone cement is injected into the collapsed vertebra to stabilize it and quickly relieve pain.
Recovery & Long-term Effects
Most spinal fractures heal within 6 to 12 weeks. However, there are important long-term considerations, especially for patients with osteoporosis:
When multiple vertebrae collapse into a wedge shape, it can cause the spine to curve forward, creating a hunched back appearance (kyphosis).
Having one osteoporotic spinal fracture significantly increases the risk of having another. Managing bone density through medication and diet is critical.
Persistent, dull back ache is common after the bone has healed, requiring long-term physical therapy and core strengthening.
