Abstract

Introduction: The purposes of this study were to identify the 2 year rate of reoperation and determine patient-reported outcomes after elective one- and two-level anterior cervical discectomy and fusion (ACDF) with structural allograft and anterior plating using indications similar to cervical disc arthroplasty.

Materials and methods: A retrospective chart review was performed on 116 consecutive one- and two-level primary ACDF for adult degenerative disease with structural allograft and anterior plating in one surgeon's practice. Patient-reported visual analog score (VAS), Oswestry disability index (ODI) and radiographs, collected prospectively on all operative patients preoperatively and postoperatively at 6 weeks, 3 months, 6 months, 1 year, and 2 years were reviewed. Patient demographics and reoperation rates were obtained from the chart.

Results: One hundred and four patients were identified with a final reoperation rate of 2.9% at a mean final follow-up 2 years (95% CI 17.2-29.0). No reoperations occurred within 90 days. After 1 year, three patients required reoperation. The mean patient-reported outcomes improved (VAS, 6.6 preoperatively to 3.0 at final follow-up and ODI, 24.3 preoperatively to 12.3 at final follow-up). These improvements were statistically significant (p < 0.01). No significant patient risk factors for reoperation were found.

Conclusions: The rate of reoperation for one- and two-level anterior cervical discectomy and fusion at follow-up was found to be lower than those previously published in the literature quoted for CDA. Arthrodesis continues to demonstrate improvements in patient-reported outcomes.
