What It Is

Vertebral compression fractures are fractures that occur when a vertebra (one of the bones of the spine) breaks and collapses. The most common cause is osteoporosis, a condition in which the bones become thin and fragile, but they can also be caused by trauma to the back and by cancer, either spreading to the bone from elsewhere or starting in the spine, such as multiple myeloma (MedlinePlus, 2025). Symptoms usually include back pain, which can come on suddenly and be severe, although some fractures cause no symptoms at first. In rare cases they can cause numbness, tingling, weakness, difficulty walking or loss of control of the bladder or bowel (MedlinePlus, 2025).

By far the biggest cause of wedge fractures is osteoporosis (MedlinePlus, 2025). If the spine is osteoporotic, the bone is thinner and even small traumas or falls can cause a collapse. In fact, the fracture is often the first sign that a person has weak bones (AAOS, n.d.). The collapse can even happen during everyday activities such as reaching, twisting, coughing or sneezing, so some people have no memory of a fall or injury (AAOS, n.d.).

These fractures often happen after a fall (AAOS, n.d.). The most common place for spinal fractures is the level between the upper and lower back, known as the thoracolumbar junction, around the T12 and L1 vertebrae and the vertebrae next to them, such as T11 (Ghadiyaram et al., 2024). This is roughly at the level of the waistline (AAOS, n.d.).

Your doctor can use several different tests to confirm whether you have one of these fractures.

Vertebral Crush / Compression Fracture Anatomy

Bones in the spine are known as vertebrae (plural); there are 24 of them, stacked one on top of each other (AAOS, n.d.). They are joined by facet joints and by the discs that sit in between each vertebra. Spinal nerves leave the spinal cord at each level through openings between the vertebrae, known as foramina.

When the vertebra crushes or collapses, it tends to collapse at the front while the back stays intact (AAOS, n.d.). This is why compression fractures are sometimes known as "anterior wedge fractures". As the bone at the front of the vertebra collapses, it forms a wedge shape. The severity of the fracture affects how much wedging occurs. Also, if there is underlying weakness in the bone, for example from osteoporosis, the wedging is likely to be more pronounced.

In a younger person without osteoporosis, the trauma would need to be significant, such as a bad fall or a car accident, to have enough force to fracture the vertebra.

How to Diagnose a Compression Fracture to the Spine

Diagnosis is not always easy and it's possible for these fractures to be missed. Some cause no symptoms at first and are only found on X-rays taken for another reason (MedlinePlus, 2025). In some cases the history alone strongly suggests a fracture, for example if a person known to have osteoporosis has had a fall. However, in many cases the pain can seem like other problems in the spine. Your doctor will examine your spine and posture, press on parts of your back to find where the pain is coming from, and check your nerves for numbness, reflex changes or weak muscles (AAOS, n.d.).

An X-ray is usually used to look for a compression fracture. An MRI scan can show whether the fracture is new, and a CT scan can show whether the fracture has spread into the spinal canal. Your doctor may also check for osteoporosis with a bone density scan, called a DEXA scan (AAOS, n.d.).

Problems Following a Crush Fracture to the Spine

In the early days there will be pain around the injury site. It often gets worse when you move, especially when changing position, and resting or lying down often helps (AAOS, n.d.). Many people recover well: a spinal fracture usually takes between 6 and 12 weeks to heal (Royal Osteoporosis Society, 2022), and most people feel better within 3 months without surgery (AAOS, n.d.).

The broken bone heals in its new, compressed shape, which can lead to some loss of height and a change in body shape (Royal Osteoporosis Society, 2022). For some people, pain continues after the fracture has healed. This is caused by the change in the shape of the spine, which can strain the joints, ligaments and muscles of the back, irritate nerves, or make existing arthritis worse (Royal Osteoporosis Society, 2022). If you still have pain after three months, there are things that can help you manage it, so talk to me or your family doctor or nurse practitioner.
