BYU engineers conceive disc replacement to treat chronic low back pain
Date:6/12/2012

In between the vertebrae of the human spine are 23 Oreo-sized, cartilage-filled discs that hold the vertebrae together and allow for spine movement.

While the discs are critical for movement, they can become the source of back pain when they degenerate or herniate a major health problem that affects 85% of Americans and drains the U.S. economy to the tune of $100 billion every year.

A new biomedical device to surgically treat chronic back pain an artificial spinal disc that duplicates the natural motion of the spine has been licensed from Brigham Young University to a Utah-based company.

The artificial disc was conceived by engineering professors Anton Bowden and Larry Howell and BYU alum Peter Halverson. It will be developed to market by Crocker Spinal Technologies, a company founded by BYU President's Leadership Council member Gary Crocker and headed by BYU MBA graduate David Hawkes.

The BYU researchers report on the mechanism's ability to facilitate natural spine movement in a study published in a forthcoming issue of the International Journal of Spine Surgery.

"Low back pain has been described as the most severe pain you can experience that won't kill you," said Bowden, a BYU biomechanics and spine expert. "This device has the potential to alleviate that pain and restore the natural motion of the spine something current procedures can't replicate."

Currently, the most common surgical treatment for chronic low back pain is spinal fusion surgery. Fusion replaces the degenerative disc with bone in order to fuse the adjacent segments to prevent motion-generated pain.

Unfortunately, patient satisfaction with fusion surgery is less than 50 percent.

The solution researched by the BYU team, and now being developed by Crocker Spinal Technologies, consists of a compliant mechanism that facilitates natural spine movement and is aimed at restoring the function of a healthy spinal disc.'/>"/>
