Comparing the Bridge‐Type Zero‐Profile Anchored Spacer (ROI‐C) Interbody Fusion Cage System and Anterior Cervical Discectomy and Fusion (ACDF) with Plating and Cage System in Cervical Spondylotic Myelopathy

Abstract

Objective To compare the clinical efficacy and radioactivity of the bridge‐type zero‐profile anchored spacer (ROI‐C) interbody fusion cage and anterior cervical discectomy and fusion with plating and cage system (ACDF) for cervical spondylotic myelopathy (CSM). Methods This is a retrospective contrastive study. We recruited 35 patients who received ROI‐C (ROI‐C group) and 34 patients who received ACDF (ACDF group), between January 2014 to January 2019, at our treatment center. The ROI‐C group comprised of 11 males and 24 females with a mean age of 61.59 ± 8.21 years (range, 51–71 years). The ACDF group comprised of 12 males and 22 females with a mean age of 60.15 ± 7.52 years (range, 52–74 years). Neck Disability Index (NDI), Japanese Orthopaedic Association score (JOA), Odom's score, cervical Cobb angle, fusion rate, adjoining ossification, and dysphagia. Results A total of 69 patients met the inclusion criteria, and these patients received more than two years of follow‐up. There were significant differences in surgical duration (101 ± 22 min vs. 118 ± 29 min) and blood loss (102 ± 46 ml vs. 145 ± 58 ml) between two groups (P 0.05). Conclusion Both ROI‐C and ACDF achieved good therapeutic effects. However, ROI‐C can reduce the operation time and postoperative complications.
