Objective: The purpose of this study was to analyze the cervical range of motion (ROM) after revised C1-C2 pedicle screw fixation for pediatric @entity1 with @entity8432 . Methods: 17 pediatric @entity1 (age range 5-14 years; mean 8.3 years) underwent the revised C1-C2 pedicle screw technique. Pre- and postoperative cervical ROM during flexion/extension, rotation and lateral bending were measured using a head-mounted motion goniometer. Plain radiographs, CT scans and MRI were performed to assess @entity1745 , the accuracy of screw placement, and bone fusion. The American Spinal Injury Association classification was used to evaluate neurological function. Results: Revised atlantoaxial pedicle screw fixation was successfully performed in all 17 pediatric @entity1 . There were no perioperative complications. All cases showed evidence of bone fusion 6 months after surgery by CT scan. During the follow-up period (24-92 months), of 6 @entity1 with preoperative @entity602 , 3 improved from grade D to grade E and 3 from grade C to grade D. The final follow-up cervical ROM was significantly greater than the preoperative and 6-month postoperative ROM. There was a statistically significant difference between preoperative and 6-month postoperative ROM for flexion, extension, and left and right @entity717 . Conclusion: As a short-segmental fixation technique, revised C1-C2 pedicle screw fixation can provide effective biomechanical stability. Final follow-up cervical ROM is significantly increased through alleviating cervical @entity158 and symptoms of @entity602 after surgery and possible subaxial compensation.    2014 S.
