Triangle Orthopaedic Associates has wrapped up 26 surgical procedures as part of a national clinical trial focusing on the safety and effectiveness of artificial discs.

The Durham-based firm is working with SpinalMotion, a California-based company that developed the Kineflex cervical disc implant. The disc includes two metal endplates and a metal core. It replaces diseased cervical discs.

Triangle Orthopaedic is one of 23 participating sites in the study. The discs are designed to help patients suffering with severe pain.

“I am very proud of our contribution to this national study,” said Thomas Dimmig, MD, a spine surgeon with Triangle Orthopaedic who is a principal investigator for the clinical study. “In addition, I believe our patients benefit from our commitment to clinical research and our drive to provide solutions to spine disorders.”

Other Triangle Orthopaedic surgeons participating in the trial were David Musante and Ralph Liebelt.
