Abstract

Purpose: This study compared the results of anterior cervical discectomy and fusion with autogenous bone graft (AFA) with or without plate fixation through a retrospective review of one or two-level degenerative cervical disorder, and the average follow-up was 6 years.
Material and Methods :Group A (n=40) underwent one-level (A-1/26) or two-level (A-2/14) fusion and AFA alone. Group B (n=36) underwent one-level (B-1/24) or two-level (B-2/12) fusion and AFA with plate construct. The following parameters were analyzed: the fusion rate, the change of Cobb’s angle, the adjacent level degeneration (ALD), the clinical outcome and the rate of complications.
Results:There was a significant difference in the fusion rate between group A and B (p=0.028). Group B had a significant increase in the change of Cobb’s angle compared to groups A (p=0.004). ALD were developed in 16 of 40 cases (40%) in group A, and in 4 of 36 cases (11%) in group B. There was a significant difference in ALD between group A and group B (p=0.004).
Conclusion: We think that plate augmentation is necessary for the maintenance of lordosis, for reducing the pseudarthrosis and adjacent level degeneration, and to improve the clinical outcome after treatment of degenerative cervical disorders.
