Standalone versus Anterior Cervical Plating for One-To-Two Level Anterior Cervical Discectomy and Fusion: A Propensity Score-Matched Comparative Study

Abstract

Anterior cervical discectomy and fusion (ACDF) can be performed with and without supportive anterior cervical plating. Fusion rates, incidence of dysphagia, and repeat surgery are concerns when performing ACDF with or without plating. We aimed to compare procedural success and outcomes between patients treated with and without cervical plating for 1-2 level ACDF. A prospectively maintained database was retrospectively searched for patients who underwent 1-2 level ACDF surgery. Patients were divided into cohorts treated with plating and without (standalone). Propensity score matching (PSM) was performed to eliminate selection bias and control for baseline comorbidities and disease severity. Patient demographics (including age, body mass index, smoking status, diabetes mellitus, osteoporosis), disease presentation (cervical stenosis, degenerative disc disease), and operative details (number of operative levels, cage type used, intraoperative, and postoperative complications) were recorded. Outcomes assessed were fusion observed at 3, 6, and 12months, patient-reported postoperative pain, and any repeat surgeries. Univariate analysis was performed according to data normality and variables for PSM cohorts. A total of 365 patients were identified (plating=289, standalone=76). After PSM, 130 patients (65 in each group) were included for final analysis. Similar mean operative times (101.3±26.5-standalone; 104.8±32.2-plating; P= 0.5) and mean hospital stays (1.2±1.8-standalone; 0.7±0.7-plating; P= 0.1) were noted. Twelve-month fusion rates were also similar (84.6%-standalone; 89.2%-plating; P= 0.6). Repeat surgery rates were equivalent (13.8%-standalone; 12.3%-plating; P= 0.8). In this propensity score-matched case-control study, we report comparable effectiveness and outcomes of performing 1-2 level ACDF with and without cervical plating.
