What Is an Osteoporotic Spinal Fracture?
A vertebral body weakened by osteoporosis can collapse under upright load. These fractures occur with small strains such as a mild fall, bending or even coughing, and sometimes spontaneously; they are most common at the thoracolumbar junction (T12-L1). Each fracture causes a loss of vertebral height and, over time, loss of body height. An important caution: one fracture markedly raises the risk of further fractures — so even a single fracture is reason enough to take osteoporosis seriously.
Symptoms
In an acute fracture the typical finding is sudden, severe back pain, often beginning with a minor trigger; the pain is marked at the fracture level, worsens on sitting up and turning, and eases when lying down. When several fractures accumulate, progressive height loss and a forward hunch can develop, which may affect breathing and balance. Some fractures are silent and are found incidentally on imaging done for another reason. Nerve compression is rare but, if it occurs, leg pain or weakness may be added.
Diagnosis: Acute or Old?
Assessment begins with plain X-ray, which shows the collapse in vertebral height. MRI is critical for distinguishing whether the fracture is new (acute) or old, and helps exclude nerve compression and other causes such as tumor or infection. CT shows the bony structure and any fragment displacement. The degree of osteoporosis is measured by bone densitometry (DEXA). The treatment decision is made according to the age of the fracture, the severity of pain and the general condition.
Conservative Treatment First — Surgery Is Not Mandatory
Most cases heal within weeks with conservative treatment: short-term pain management, early mobilization, brace support in selected patients and physiotherapy. In cases with pain resistant to conservative care and severe enough to prevent movement, minimally invasive augmentation is considered: vertebroplasty (injecting bone cement into the fractured body) or kyphoplasty (first gaining height with a balloon and then injecting cement). With marked nerve compression or instability, more extensive surgery may be needed.
The Real Treatment: Osteoporosis Itself
Kyphoplasty can provide relief in a painful fracture, but the foundation of preventing new fractures is treating osteoporosis. Adequate calcium and vitamin D, regular weight-bearing exercise, stopping smoking and excess alcohol, reducing the risk of falls and the medication prescribed by the physician form a whole. If a spinal fracture has occurred, preventing a second is as important as treating the first. Outcomes vary individually with age, bone quality and accompanying conditions; no outcome is guaranteed.
