Hoag Hospital Chosen as One of Two California Sites for Clinical Investigation of Cervical Artificial Disc Replacement

NEWPORT BEACH, Calif., Feb. 27 /PRNewswire/ -- The Institute for Spine at Hoag Memorial Hospital Presbyterian is the only Orange County facility participating in a national clinical investigation of cervical artificial disc replacement surgery. The procedure is targeted for the treatment of cervical disc disease, resulting from disc degeneration or injury to the cervical vertebrae -- or bones of the neck.

The FDA-regulated clinical trial, which includes the participation of 20 sites nationwide, is being headed locally by neurosurgeon William R. Dobkin, M.D., and orthopedic surgeon J. Carlisle Brown, M.D. Hoag Hospital was chosen as one of two sites in California to participate in the trial.

"At Hoag's Institute for Spine, the close partnership between orthopedic surgeons and neurosurgeons creates a unique synergy between the medical specialties," explains Dr. Dobkin. "Our multi-disciplinary approach keeps us on the forefront of new medical approaches, and if this clinical investigation succeeds, it will be a major advance for spine surgery."

Cervical disc disease occurs when the gel-like discs between the vertebrae of the neck become dislodged due to accidents, muscle strain, arthritis or aging. The condition may impinge on the spinal cord or nerves, often resulting in neck pain, radiating arm pain and temporary changes in nerve function that may cause tingling, lack of coordination, numbness or weakness in an arm or hand.

The traditional surgical option for cervical disc disease is disc removal followed by spinal fusion. About 200,000 cervical procedures are performed annually in the United States, many of which involve the placement of bone graft and a metal plate to help rigidly fuse or weld the vertebrae together. Patients' symptoms are subsequently relieved, but the fused vertebrae can limit neck movement and may put additional stress on the discs above and below the fusion.

With cervical artificial disc replacement surgery, a small prosthetic device with an elastic nucleus, known as the Bryan(TM) Cervical Disc Prosthesis, is inserted into the vertebrae to replace the removed disc. This investigational device is designed to provide the motion and elastic characteristics of the natural cervical disc.

"We are interested in determining if this investigational procedure will result in better and more natural range of motion for patients, and enhanced long-term preservation of adjacent normal discs than with the traditional surgical option of fusion," explains Dr. Brown. "Additionally, while recovery time from this investigational procedure is consistent with fusion, patients are spared from wearing a brace post-operatively."

The Bryan(TM) Cervical Disc Prosthesis was first implanted in Belgium in January 2000. Since that time, more than 1,000 patients outside North America have had the procedure, and the device is currently distributed in more than 17 countries.

Approximately 10 patients are expected to receive the investigational device at Hoag Hospital during the next six months-with a total of approximately 200 nationwide. Patients undergoing the clinical trial at Hoag Hospital are being carefully screened for participation. Additionally, as part of the trial, patient outcomes will be closely monitored for 24 months following the procedure.
