［Objective］ To analyze the outcome of internal fixation for occipitalization with atlantoaxial joint dislocation by posterior decompression and occipitocervical fusion ［Method］ From December 2005 to June 2007,8 patients with occipitalization and atlantoaxial joint dislocation received removal of the posterior arcus of atlas and the enlargement of the posterior edge of the foramen magnum after skull traction performing for an average of 135 daysAll patients were operated on by posterior craniocervical fusion using cervifix internal fixation system and autologous ilium graftsThe clinical efficacy after operation was analyzed by Japanese Orthopaedic Associationneural function score ［Result］ All the patients were followed up from 6 months to 2 years, average of 15 monthsNo complication was foundAtlantodental interval was 5~9 mm before and 4~6 mm after skull tractionAtlantoaxial joint dislocation didn't completely reducedThe neurological defects were improved to some extents according to the JOA scoreImageology showed all patients had full decompression and bony fusionThe loosening or broken internal fixation was not found ［Conclusion］ Posterior decompression and fusion is a feasible method for the treatment of occipitalization with atlantoaxial joint dislocation,and the clinical effect is satisfactory

分析后路减压枕颈融合内固定术治疗合并寰枢关节脱位的寰椎枕骨化临床疗效。［方法］2005年12月至2007年6月间，对8例合并寰枢关节脱位的寰椎枕骨化患者在行颅骨牵引治疗一段时间（12~16 d，平均135 d）后采用枕骨大孔后缘扩大，寰椎后弓切除减压取自体髂骨枕颈融合Cervifix系统内固定术，手术后采用日本骨科学会神经功能评分分析临床疗效。［结果］8例患者随访6个月~2年，平均为15个月。8例患者无一例出现术后并发症，术前寰齿前间隙为5~9 mm，经颅骨牵引后为5~7 mm，寰枢关节脱位未能完全复位。手术前后JOA评分示神经症状均有不同程度恢复，影像学检查示枕颈区减压充分植骨区获得骨性融合，无一例出现内固定松动或断裂。［结论］合并寰枢关节脱位的寰椎枕骨化患者术前仔细评估影像学改变，采用颅骨牵引一段时间后行后路减压枕颈融合内固定术的治疗方案是合理可行的，且临床效果满意。

The use of locked periarticular elbow plates improves the stability of the fixation and allows fragment specific angle-stable fixation especially with the comminuted C3 types.23 The exposure needed for this fixation is similar to conventional distal humeral double plating.
