Outcomes Good in Clinical Trial of Artificial Cervical Disc
Preliminary data suggests that cervical disc arthroplasty may be viable alternative to fusion
THURSDAY, April 27 (HealthDay News) -- Cervical disc arthroplasty with the Prestige ST artificial cervical disc is associated with significantly greater maintenance of neck motion in patients with single-level cervical disc disease, compared to standard treatment, according to preliminary research presented this week at the annual conference of the American Association of Neurological Surgeons in San Francisco.
Praveen V. Mummaneni, M.D., of Emory University in Atlanta, and colleagues randomized 120 patients with symptomatic cervical disc disease to receive either cervical discectomy and implantation of the Prestige ST device, or the standard treatment of cervical discectomy and fusion.
The researchers found that all postoperative outcome scores improved for both groups. But radiographic analysis showed that the Prestige device helped maintain and restore segmental motion, with most patients in the Prestige group demonstrating significantly greater maintenance of neck motion than patients in the fusion group. They reported that no revision surgeries occurred in the Prestige group compared to two revisions in the fusion group.
"Early results from the clinical trial are encouraging and indicate that the Prestige ST artificial cervical disc may become a viable alternative to cervical fusion in the near future," Mummaneni said in a statement.
