用15只兔分3组：A组为完全离断小腿胫后动脉缝接胫后静脉组，B组为部分离断小腿胫后动脉缝接胫后静脉组，C组为完全离断小腿应用传统的胫后动脉缝接胫后动脉对照组，3组均结扎胫前动脉，保留胫前静脉等未动脉化的静脉及缝接其它离断软组织。

［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。

与posterior相关的网络解释 [注：此内容来源于网络，仅供参考]

posterior：[后]

现代解剖学对盆底结构描述日趋细致,腔室理论是代表,它的特点是:在垂直方向上将盆底分为前(anterior)、中(middle)、后(posterior)三个腔室(compartment),前腔室包括阴道前壁、膀胱、尿道;中腔室包括阴道顶部、子宫;后腔室包括阴道后壁、直肠;

posterior：后部

轴向压力大部份为椎间盘所承受,且最大等效应力集中於椎间盘后部(posterior). 除了轴向位移外,亦产生偶合运动,即向后位移及后仰(extension). 作用力的中心线、椎体之几何中心,及脊椎之前弯角度(lordosis)与应力的分布、运动量有很大的关系.

posterior：后面

改变的数量不多,且主要和方向性的辞汇有关:以后面 (posterior) 取代背面 (dorsal),以前面 (anterior) 取代腹面 (ventral) 等等. 在大部分的情况下,之前的辞汇会接在正式辞汇的后面,且以括弧表示;例如,posterior (dorsal) cochlear nucleus.

posterior：后路

后路颈椎间孔切开术/椎间盘切除术是从颈椎后方对神经根施行减压的手术方法. 此术语源自后路(posterior)、颈椎(cervical)、椎间孔切开术(foraminotomy) 和椎间盘切除术(discectomy)这几个词.

Posterior distribution：后验分布

参数被看成是随机变量,它的概率分布有两种:第一种是在试验之前就已经知道的被称为先验分布(prior distribution),它可以通过对以往的关于参数的知识进行总结作一个主观判断得到;第二种是在试验之后得到的被称为后验分布(posterior distribution).
