Abstract：Objective To develop a butterfly-style occipitocervical fixation system applied in upper cervical spine surgery for underage children, and to explore its preliminary applicable effect. Methods A set of occipitocervical fixation device with low-profiles and multi-anchor points was designed according to pediatric anatomic characteristics, and the clinical effect was observed in one child applied with the system. Results Being consisted of butterfly-style occipital plate, pedicle screws and titanium rod (3.5 mm), butterfly-style occipitocervical fixation system was developed successfully. The system was applied for a 2-year-old child with atlantoaxial dislocation. Postoperative results showed that atlantoaxial reduction was obtained, spinal cord compression was relieved and fixation placement position was satisfactory. The patient was followed-up for 1 year, during the follow-up, spinal function was improved significanly, and normal walking function was restored. Conclusion Novel butterfly-style occipitocervical fixation system could improve the occipital fixation rigidity, and is suitable for underage children who have to receive upper cervical spine surgery.
