Methods 8 cases of atlantoaxial fractures and dislocations were treated with Apofix lamina clamp internal fixation.

对8例寰枢椎骨折、脱位患者采用Apofix椎板夹固定。

Results In the 43 cases,there were 12 cases C1 fractures,20 C2 spinous process fracture,4 C2 axoid fractures,4 Hangman fracture,and rotated atlantoaxial dislocation in 1.Only 1 case was simple ligamentum transversum injury.

结果 43例中，C1骨折12例，C2齿状突骨折20例，C2椎体骨折4例，C2椎弓骨折4例，单纯性寰枢关节旋转脱位2例，单纯横韧带损伤1例。

Objective To investigate the method and effect of the treatment of atlantoaxial fracture and dislocation.

目的 探讨应用Apofix椎板夹治疗寰枢椎骨折、脱位的方法及疗效。

［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。

Methods. A 26-year-old man with Down syndrome suffered from retropharyngeal infection, after which his atlantoaxial subluxation was aggravated and myelopathy developed.

一26岁男性唐氏综合症患者，在咽后部感染后，继发日益严重的寰枢椎半脱位，并发生脊髓病。

Methods: 28 rabbits were divided into 3 groups (4 animals for every group). All animals were dissected to keep the spine and the pelvis, hip joint, the upper part of the femur, with the anterior and posterior longitudinal ligaments, intervertebral disk and psoas muscle, erector spinae, and supraspinal ligament attached to it.

取家兔12只，分3组，每组4只，解剖后保留枢椎以下完整之脊柱及骨盆、髋关节、上段股骨，不损伤脊柱前、后纵韧带、椎间盘及所附着之腰大肌，保留脊柱背侧的竖脊肌、棘上韧带，置于生物力学拉伸测试仪（日本岛津制作所产AGS-J系列）。

Results. The normal atlantoaxial relation was restored and the torticollis resolved.

结果：手术恢复了正常寰枢椎关系，并纠正了斜颈。

There is great suitability of C(subscript 2/3) transarticular screw fixation, and it could be used as an alternative screw anchor point for posterior cervical instrumentation.

经C(下标 2/3)侧块关节进行螺钉固定在解剖学上是可行的，可以作为枢椎后路螺钉固定的补充方法。

The second part aims to investigate a new method to analyze the cervical rotatory manipulation safety by the finite elements analysis of the odontoid process,since nowadays,there is few basic researches on biomechanics and quite a lot miscarriages take place when the cervical rotatory manipulation is applied in the clinic.

第二部分，针对目前临床颈部推拿失误较多，生物力学基础研究薄弱的状况，对颈椎枢椎齿突受力情况进行有限元分析，以此探讨新的颈椎推拿安全分析的方法。
