寰枢椎骨折脱位后路内固定植骨融合术

[目的]探讨寰枢椎骨折脱位后路内固定植骨融合术的方法和疗效。[方法]在气管插管全麻下对26例寰枢椎骨折脱位的患者施行后路内固定植骨融合术。对有椎体后弓和椎板骨折者采用枕颈内固定（Aixs）植骨融合术，对无椎体后弓和椎板骨折且无需行椎管减压的寰枢椎骨折采用椎板夹（Apofix）内固定。[结果]随访5～60个月，平均16．8个月。全组病例未发生椎动脉或脊髓损伤等并发症。术后临床症状均得到较好改善，X线片复查提示椎体侧块关节突和枕骨髁部螺钉位置良好，无松动或断钉现象，植骨3个月均达到骨性融合。[结论]Aixs内固定植骨融合术或Apofix内固定术是治疗寰枢椎骨折脱位的有效方法之一。

Posterior internal fixation and bone grafting fusion for atlantoaxial fracture or dislocation

[Objective]To evaluate the method and curative effect of posterior internal fixation and bone grafting fusion for atlantoaxial fracture or dislocation.[Method]Posterior internal fixation and bone grafting fusion were made on 26 patients with atlantoaxial fracture or dislocation in condition of tracheal intubation anesthesia.Occipitocervieal fixation(Aixs) and bone grafting fusion were performed on patients with fracture of vertebral lamina-arch.Vertebral lamina splint fixation (Apofix) was performed on patients without fracture of vertebral lamina-arch and decompression of vertebral canal.[Result]Followed up for 5 to 60 months(averaged,16.8 months),the vertebral artery and spinal cord injury were not occurred and clinical symptom was relieved in all patients.X ray examination showed screws in vertebral articular process and occipital condyle were normotopic without laxation and fragmentation.The bone grafting transformed into osseous fusion after 3 months.[Conclusion]Aixs fixation and bone grafting fusion and Apofix fixation are effective methods for atlantoaxial fracture or dislocation.
