Abstract:
Objective To summarize the clinical results of posterior fusion plus pedicle screw fixation in treatment of dens fracture combined with recoverable atlantoaxial dislocation. Methods Twenty-seven patients with dens fractures combined with recoverable atlantoaxial dislocation were treated with posterior pedicle screw fixation, reduction and fusion. In this series of patients, skull traction was made to restore the normal atlantoaxial joint before the operation. Results Atlantoaxial alignment or stability were restored, without complication due to instrumentation. A follow-up for 12-48 months (average 24 months) showed osseous union. Conclusion Posterior aflantoaxial pedicle screw and rod fixation provides immediate three-dimensional rigid fixation of aflantoaxial joint and is a more effective technique compared with previously reported techniques.
