Objective To study the influence of different fusion methods in intervertebral height of patients with cervical spondylotic myelopathy after cervical anterior corpectomy. Methods 65 patients with cervical spondylotic myelopathy who accepted cervical anterior corpectomy during May, 2010 to July, 2012 were selected. 20 patients accepting autogenous iliac bone grafting were divided into the control group. 20 patients accepting titanium mesh cages without end caps were divided into the non-caps group while 25 patients accepting titanium mesh cages with modular end caps were divided into the modular caps group. The change of intervertebral height of patients before and after the surgery and the incidence of the complication of all the patients were compared. Results The difference of height of the anterior border and posterior border before and after the surgery was not statistically significant (P>0.05). The loss of the height of the anterior and posterior borders of the intervertebral height of the modular caps group in 1 year after the surgery was statistically less than that of the other two groups(P<0.05). The incidence of the modular caps group after the surgery was statistically less than that of the other two groups (8% vs 45%, 40%；χ2=8.236, 6.583 P=0.004, 0.010). Conclusion The application of modular end caps in cervical anterior corpectomy could maintain the cervical intervertebral height postoperatively and reduce the postoperative subsidence rate of titanium mesh cage, which is worth further promotion.
