There is little evidence that two surgical procedures commonly used to treat spinal fractures caused by osteoporosis reduce pain for patients better than pharmaceutical drugs, according to a new report by an international task force of bone health experts published in the Journal of Bone and Mineral Research..

More than 10 million Americans suffer from osteoporosis, a loss of calcium and bone density that worsens over time and significantly raises the risk of bone fractures, especially among the elderly. About 750,000 spinal fractures occur each year in the United States alone.

The task force looked at two types of spinal fusions: vertebroplasty, where medical grade cement is injected into the broken vertebrae to fuse bone fragments together; and balloon kyphoplasty, where a balloon is inserted into the compressed area of the spine to lift it and allow the cement to be inserted. Metal plates, screws and rods can also be used in spinal fusions, but were not the focus of the study.

The researchers found little to no evidence that vertebroplasty or kyphoplasty relieve pain effectively. In five clinical studies, vertebroplasty provided no significant benefit in pain control over placebo or sham procedures. There were no placebo-controlled trials for balloon kyphoplasty, leaving doctors to rely on anecdotal, low-quality evidence.
