BACKGROUND: Autogenous bone has been used in cervical vertebra graft bone fusion in earliest stage and at most. However, its source is limited, simultaneously, induced many complications such as infection, hemorrhage and postoperative pain in the donor bone region. Recently, above-mentioned complications were avoided or reduced with the usage of new graft bone fusion material. OBJECTIVE: To compare clinical efficacy using MC+~R combination of autogenous bone or calcium sulfate artificial bone in antador cervical fusion.METHODS: A total of 26 patients (34 levels) with cervical spondylotic myelopathy underwent anterior cervical discectomy and cervical intervertebral fusion from January to December 2008. Anterior cervical oblique cut was 3.0-4.0 cm. The endplate were preserved after the cervical intervertebral disc and the posterior longitudinal ligament were removed. Autogenous bone group was filled with autogenous bone. Calcium sulfate artificial bone group was filled with Wdght's Osteoset artificial bone. Anchoring clip was implanted between the cervical vertebrae. Every patient had a short neck incision was assessed with X-ray, JOA grade and Odom's evaluation scale.RESULTS AND CONCLUSION: The two groups of 26 patients (34 segments)were followed up. The JOA score of postoperation was no significant difference between the two groups. According to the Odom's evaluation scale, the excellent and good rate of calcium sulfate group was higher than autogenous bone group, but there was not statistical significance (P>0.05). The fusion rate of autogenous bone group was higher than calcium sulfate group at 3 and 6 months, but the fusion rate of two groups were 100% at 12 months. Although the calcium sulfate group at 6 months, lordosis angle lost more than 0.4°than the autogenous bone group,but no significant statistically between the two groups (P>0.05). MC+ combination of autogenous bone or Calcium sulfate had the same clinical efficacy in the treatment of cervical spondylotic myelopathy, but the calcium sulfate artificial bone could be effectively avoided the complications of donor site.
