Compression fractures are the result of "crumbling or smashing of cancellous bone by forces acting parallel to the long axis of bone. It is applied particularly to vertebral body fractures."[1]

Cause / etiology

Compression type fractures can occur to any bone when an applied force overwhelms the ability of the trabecular structure of that bone to resist the pressure. Compaction of the bone occurs and a loss of height or size of the particular structure, most commonly a vertebra, results. A single traumatic injury may precipitate the fracture or, in the case of chronic disease, multiple tiny compressions occur over time with a slow loss of height. Under normal circumstances, healthy bone requires a significant fall or impact to cause compression, but more commonly, diseases that weaken the trabecular matrix within cancellous bone lower the threshold required to cause the bone to collapse. Spontaneous compression fractures appear to occur for no reason at all when a cough or a sneeze triggers the collapse. Essentially, the bone has become so weak that normal weight bearing is no longer possible. Conditions that can result in spontaneous compression fractures include those that cause osteopenia, or calcium loss within the bone, such as osteoporosis, metabolic diseases, metastatic cancer and lymphoma among others.

Diagnosis

Compression fractures of the spine are generally identified by the patient history of back pain, tenderness in the area of the fracture, and spasm or contracture of the surrounding musculature. The presence of hyperkyphosis (hunchback) may be a sign of an underlying compression fracture as about one third of cases have vertebral fractures.[2]

Xray is the most common test for detecting and confirming compression fractures, though Computed Tomography (CT scan) and bone scan can show early signs of disruption of the trabecular pattern especially in those resulting from underlying disease. A triple phase bone scan is particularly useful in determining the age of the compression when timing of the injury is critical for treatment purposes. Magnetic Resonance Imaging (MRI) will show an increased signal if inflammation is part of the process.

Treatment

Depending on the cause and severity of the vertebral compression fracture, treatment will include medication to control pain, inflammation or muscle spasm. Injection of calcitonin may reduce pain.[3] It might also include bracing or casting to prevent further collapse until healing can occur.

Invasive treatment

Invasive treatments may include balloon kyphoplasty and vertebroplasty.

Balloon kyphoplasty uses a specialized balloon in an attempt to restore as much of the original height of the vertebra as possible before applying the cement and removing the balloon, minimizing the spinal distortions. Balloon kyphoplasty may reduce pain according to an industry sponsored randomized controlled trial.[4]

Vertebroplasty injects a cementlike paste into the compacted vertebra in an effort to prevent further collapse. Vertebroplasty does not seem to help according to blinded randomized controlled trials.Cite error: Closing </ref> missing for <ref> tag Vertebroplasty was helpful in a subsequent randomized controlled trial that was not blinded.
