Pittsburgh-based Allegheny Health Network neurosurgeon Donald Whiting, MD, is developing an artificial spinal joint, according to CBS Pittsburgh.
The joint replacement is currently being studied in patients suffering from spinal stenosis with back pain and leg symptoms. Study participants must have complications at only one level and a relatively health intervertebral disc. Patients are randomly assigned to undergo spinal fusion or receive the artificial joint.
The investigational artificial joint features a shock absorb design to allow the patient to bend forwards and backwards. "It's really good for people who are young and active, who would normally need a fusion, but this is a good way to maintain motion," Dr. Whiting told CBS.
If the study demonstrates the artificial joint is noninferior to spinal fusion, it will go before the FDA for approval.
