    Study DesignA retrospective chart review was conducted at a single institution.ObjectiveThe purpose of this study was to investigate the clinical outcomes of cervical disc arthroplasty (CDA) used for the treatment of symptomatic adjacent segment disease (ASD) developed after anterior cervical discectomy and fusion (ACDF).BackgroundA major clinical concern following ACDF is the development of ASD. ASD after ACDF is often treated with an additional fusion, but risks include pseudoarthrosis and further ASD. CDA is a motion-preserving alternative that addresses these concerns, and therefore, has been proposed as an alternative treatment for ASD after ACDF.Materials And MethodsPatients who underwent CDA at level(s) adjacent to a prior ACDF (n = 120) were identified from a consecutive series of patients who underwent CDA at one institution. Pre-CDA to post-CDA patient-reported outcome measures were compared using the paired Wilcoxon signed-rank test.ResultsA total of 142 devices were implanted-98 patients underwent a 1-level CDA, and 22 patients underwent a 2-level CDA. The mean follow-up duration after CDA was 32.11 months. Neck pain, arm pain, and Neck Disability Index scores significantly improved from the preoperative to postoperative time point (respectively: 6.14-3.02, 4.42-1.61, 44.28-28.62, all P < 0.001). In total, 7 patients underwent reoperation (5.83%). One of these patients underwent reoperation for pseudarthrosis at the level of ACDF following a hybrid procedure. The indications for index level reoperations (n = 3) were foraminal stenosis, osteolysis, and postoperative hematoma. All patients with an adjacent level reoperation (n = 3) received surgery at levels adjacent to the prior fusion, not the more recent CDA.ConclusionThe results of this study found that CDA was effective for the treatment of ASD following ACDF. CDA appears to be a viable treatment option for ASD after ACDF in appropriately selected patients.Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.
