ABSTRACT

Introduction: The adjacent segment disease is a complication of spinal fusion procedures, which occurs in 25% of patients in the first 10 years, its pathophysiology is controversial. Objective: Establish whether there is a relationship between the optimal placements of a single cervical implant with the adjacent segment disease and determine differences between arthrodesis and arthroplasty. Material and methods: Analytical and retrospective study. In which two groups were evaluated (arthroplasty and arthrodesis). The postsurgical Cobb angle was evaluated using Student’s t test. The preoperative Neck Disability Index was compared to the postoperative period using the Wilcoxon test. Results: We included 31 patients with an average age of 51.4 years, the most affected level was C5-C6. The mean follow-up periods in the arthrodesis and arthroplasty group were 41.8 months and 48.6 months respectively. The EVA score for the arthrodesis group and for the arthroplasty group decreased significantly in the first, second and third consultations after surgery compared to the preoperative VAS (p ‹ 0.001). It has been shown that maintaining mobility after the placement of single-level prostheses prevents symptomatic adjacent disc disease and radiological disc disease. Conclusions: With this study we can say that for both techniques there is significant improvement in pain initially but in the long term the arthroplasty leads to a better recovery of the Neck Disability Index.
