New Anatomic Facet Replacement System continues clinical progress

Facet Solutions : 19 October, 2007  (New Product)
Facet Solutions has announced that additional surgical procedures utilising the company's Anatomic Facet Replacement System (AFRS) have been successfully completed as part of an FDA approved IDE Clinical Trial.

The AFRS is the first anatomic facet replacement device designed to provide patients with lumbar spinal stenosis and facet degeneration a motion preserving alternative to fusion.

The procedures were implemented by John Regan, MD, a board-certified orthopaedic surgeon at Century City Doctors Hospital in Los Angeles, California and Darryl DiRisio, MD, associate professor and neurosurgeon at Albany Medical College, Albany, New York.

A fusion uses metal rods and screws to join vertebrae together. While most patients report pain relief after a spinal fusion, the surgery often eliminates flexibility and range of motion, and can cause unnecessary wear on other spinal levels. By contrast, the AFRS is designed to mimic normal motion and prevent adjacent level degeneration.


The AFRS is made of two highly polished cobalt chrome implants that articulate similar to other total joints that have been used successfully in hip and knee replacements for several decades


'Until recently, people suffering from chronic lower back pain caused by lumbar spinal stenosis had few treatment options,' explained Dr Regan. 'Facet joint replacement utilising the AFRS not only relieves low back pain but also has the potential to significantly improve the patients' flexibility and range of motion.

Dr DiRisio noted that the use of facet joint replacement for the treatment of spinal stenosis following a spinal decompression is a notable advance in spinal surgery. He said: 'It offers surgeons an alternative treatment for patients who have suffered for years from this debilitating condition.'

New clinical investigator, Kenneth Pettine, MD, board-certified orthopaedic surgeon with the Rocky Mountain Spine Arthoplasty Specialists in Loveland, Colorado is looking forward to offering this new treatment option to his patients.

'Recently, I hosted a local community presentation to educate patients on the advantages of this new technology,' stated Dr Pettine. 'I was very pleased with the strong attendance and was encouraged that a third of the attendees had signed up to learn more about the AFRS trial. The potential for patients to maintain motion, and continue with the normal activities of daily living, is what I believe is driving the high level of interest in this trial.'

Note: AFRS is an investigational device in the USA. AFRS is limited by United States Federal Law for investigational use only.
