［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。

Abstract］ objective to investigate anus sphincter preserved surgical method and indication for low rectal cancer.methods 15 cases with low rectal cancer were operated with eversion and pull-through anus preserved colorectal anastomosis through anus.results no patients died of operation,no patients was with fistula and stricture of anastomosis,no defecation incontinence happened after postoperative 20 weeks,only one patient was with local recurrence.following up for 8 months to 5 years,5 cases were with distant metastasis,4 of these died,one of these had lived with liver metastasis for 3 years.conclusion the indication of anus preserved operation should be chosen according to clinical stage and biological characteristic of rectal malignancy; eversion and pull-through anus preserved colorectal anastomosis through anus is a better anus preserved operation for low rectal cancer.

目的 探讨低位直肠癌保留肛门括约肌功能的手术方法和手术适应证。方法对低位直肠癌经腹经肛门直结肠外翻拉出保留肛门吻合术15例。结果全组无手术死亡，未发生吻合口漏和吻合口狭窄，局部复发1例，20周左右恢复正常排便排气功能，无大便失禁病例。随访8个月～5年，5例为远处转移，死亡4例，其中1例肝转移3年仍生存。结论根据直肠癌的临床分期和肿瘤的生物学特性选择保肛手术适应证，经腹、肛门齿线上直肠癌根治性切除，行肛门直结肠外翻拉出吻合是低位直肠癌较好的保肛术式。
