Abstract
Background: Cervical disc arthroplasty replacement (CDA) was developed to avoid specific disadvantages of cervical fusion. The purpose of this paper is to provide 10-year follow-up results of an ongoing prospective study after CDA.
Methods: 384 patients treated using the Mobi-C (ZimVie, Troyes, France) were included in a prospective multicenter study. Routine clinical and radiological examinations were reported pre and postoperatively with up to 10-year follow-up. Complications and revision surgeries were also documented.
Results: at 10 years showed significant improvement in all clinical outcomes (NDI, VAS for arm and neck pain, SF-36 PCS and MCS). Motion at the index level increased significantly over baseline (mean ROM=7.6° vs. 8° at 5 years and 6.0° preoperatively; P<0.001) and 71.3% of the implanted segments remained mobile (ROM>3°). Adjacent discs were also mobile at 10 years with the same mobility as preoperatively. At 10 years, 20.9% of the implanted segments demonstrated no heterotopic ossification (HO). Thirty-four patients (8.9%) experienced 41 adverse events, with or without reoperation during the 5 first years. We found only two additional surgeries after 5 years. We observed an increased percentage of working patients and a decrease in medication consumption. Regarding the overall outcome, 94% of patients were satisfied.
Conclusions: Our 10-year results showed significant improvement in all clinical outcomes, with low rates of revision or failure. This experience in patients with long-term follow-up after CDA endorses durable, favorable outcomes in properly selected patients.
