SAN DIEGO — Patients treated with anterior cervical discectomy and fusion did not have any better outcomes than well-selected patients treated with cervical disc arthroplasty through 84 months follow-up, according to a presenter at the International Society for the Advancement of Spine Surgery Annual Meeting, here.

At final follow-up, the patients who underwent cervical disc arthroplasty (CDR) received the PRESTIGE LP Cervical Disc (Medtronic; Memphis, Tenn.) showed similar improvement in their Neck Disability Index, neck and arm pain and SF-36 scores to a group of patients who underwent anterior cervical disc fusion (ACDF).

“Angular motion in patients with the Prestige LP disc was well preserved at 84-month follow up,” Todd Lanman, MD, said.

In the study 280 patients underwent CDR and 265 patients underwent ACDF. Patients were followed-up through 7 years.

The improvements Lanman and colleagues observed were first evident at 1.5 postoperative months and they were maintained through 84 months of follow-up.

Lanman said segmental motion was maintained postoperatively in the CDA and the implant provided biomechanical stability for the CDA cohort. – by Robert Linnehan
