Objective: To compare results of Plate-Graff, Plate-Cage and PEEK cage in patients with cervical stenosis. Material and methods: Prospective, with before and after intervention and comparative study. From January 2005 to October 2011 we included 37 patients (male: 48.6%, female: 51.4%) post-surgery by anterior approach; 3 groups via: Group I, arthrodesis with Plate-Graff n = 12 (M 41.7%, F 58.3%) with 22 levels, group II, Plate-Cage n = 11 (M 63.6% 36.4% F) 19 levels, group III, PEEK cage, n = 14 (M 0% F 50%) with 25 levels. Functional assessment pre- and postoperative with neck disability index (NDI) and visual analogue scale for pain (VAS). The radiological assessment with X-rays only. Descriptive statistics were obtained. Wilcoxon method use according to data distribution, non parametric tests of ranges with sign of Kruskal-Wallis for comparison between more than two groups, and significance level with p ‹ 0.05. We used the statistical package SPSS version 15. Results: The majority of patients was found between the sixth and eighth decade of life. At one year of follow up the NDI and pain with VAS shown improvement with statistical difference in three groups (p = 0.001). However, the radiographic measurements per year of follow-up showed a significant improvement of segmental lordosis (p = 0.02) only in patients with Plate-Graff. Conclusions: Using the graft offers best clinical and radiographic results compared with the Plate Cage and box peek to one year of follow-up.
