【摘要】Objective To compare the radiographic outcome of three different fusion methods in maintenance of intervertebral height after cervical anterior corpectomy.Methods From May 2005 to November 2009,a total of 77 patients with cervical spondylotic myelopathy who underwent anterior cervical corpectomy and fusion were reviewed in the study.Fusion methods included autogenous iliac bone grafting in 22 patients(group 1),titanium mesh cages without end caps in 21 patients(group 2) and titanium mesh cages with modular end caps in 34 patients(group 3).No significant differences were found in age,gender or level of corpectomy among the three groups (P ＞ 0.05).The height of anterior border (HAB) and the height of posterior border(HPB) of the fused segment were measured on lateral radiographs pre-operatively,post-operatively and at final follow-up to evaluate the outcome.The incidence of subsidence of titanium mesh cage and iliac bone was also reviewed retrospectively.The statistical analysis included One-way variation analysis and chi-square test.Results All cases obtained the follow-up with an average of(30 ± 5)months (range 24 to
