OBJECTIVE: To evaluate the long-term clinical therapeutic effect of polyaxial screw-rod system for posterior cervical arthrodesis on @entity1 with @entity4097 .    Methods: From March 2007 to May 2013, 22 @entity1 with @entity4097 underwent @entity5 resection and posterior cervical arthrodesis in our institution. The medical records of these @entity1 were reviewed respectively. There were 10 males and 12 females with ages ranging from 16 to 60 years old. Posterior cervical arthrodesis by polyaxial screw-rod was performed at the upper cervical spine ( @entity18361 ). All @entity1 were followed-up clinically and radiographically.    Results: The average follow-up was 65.5 months. Twenty-two @entity1 were enrolled and a total of 114 screws were placed in this study. Histopathology revealed @entity808 , @entity1653 , @entity6010 and @entity7667 in 16, 3, 1 and 1 case (s), respectively. The @entity5 with component of @entity6010 was observed in 1 case. All @entity1 received @entity5 resection and posterior athrodesis by polyaxial screw-rod system. Cervical @entity1513 was encountered in one @entity1 and this @entity1 suffered the recurrence of @entity5 . Solid fusion was achieved in all @entity1 . The average postoperative Japanese Orthopaedic Association (JOA) score was 13.9 and the average recovery rate was 51.4%. @entity16 was found in 2 @entity1 . No complications, such as spinal cord or @entity1317 , postoperative @entity614 or instrumentation failure, were observed.    Conclusion: The long-term clinical therapeutic effects of posterior cervical arthrodesis using polyaxial screw-rod system on @entity4097 are satisfactory, with no severe complication.
