Objective To explore the techenique of fusing the reconstructed titanic plate, the C2 pedical screws, and the autogenous granulated cancellous bone graft in the occipitocervical region. Methods From April 2002 to January 2005, 19 patients aged 31-67 years with occipitocervical instability underwent the occipitocervical fusion using the reconstructed plate, C2 pedical screws, and autogenous granulated cancellous bone graft. Of the patients, 8 had complex occipitocervical deformity，8 had old atlantoaxial fracture and dislocation，2 had rheumatoid arthritis and anterior dislocation of the atlantoaxial joint, and 1 had cancer of the dentoid process of the axis． Results No complication occurred during and after operation．The follow-up for an average of 16 months in 19 patients showed that all the patients achieved solid bony fusion in the occipitocervical region．There was no broken plate, broken screw, looseness of the internal fixation or neurovascular injury. Conclusion The fixation of the C2 pedical screws with the reconstructed titanic plate is reliable, the insertion is easy, and the autogenous granulated cancellous bone graft has a high fusion rate, thus resulting in a satisfactory effect in the occipitocervical fusion.
