ABSTRACT
Objective To compare the clinical outcomes of cervical vertebral reconstruction using titanium mesh and nano-hydroxyapatite and polyamide 66 (n-HA/PA66) mesh as two different kinds of artificial vertebrae. Methods From January 2008 to June 2009 had surgically treated 37 cases of cervical spondylosis with anterior corpectomy for decompression, and artificial vertebrae implanted combined platescrews fixation for cervical reconstruction and fusion. As a vertebral substitution, titanium mesh were implanted in 25 cases ( group A ), and the others (12 cases, group B) were implanted with n-HA/PA66 mesh. The height of fusion space immediately postoperatively and the implanted condition were observed. The fusion rate and the JOA score were recorded to compare the clinical outcomes. Results Two groups received 6-20 ( 15.4 ±4.2 )months follow-up. When follow-up to the end grafts were already fusion. The preoperative JOA score in group A,B [(8.40 ±0.96) scores vs. (8.33 ±1.07) scores(P > 0.05)] were increased to (14.36 ±0.86)scores and (14.83 ±0.71) scores after postoperatively (P> 0.05),but there were statistically significant differences between preoperative and postoperative each group (P<0.05). There were 6 cases artificial vertebrae in group A and 1 case in group B subsided asymptomaticly with 100% choiceness rate. Conclusion These two kinds of artificial vertebrae could show similar outcomes in cervical vertebral reconstruction, but the n-HA/PA66 mesh has a lower subsidence rate.
