复位

objective the purpose of this study was to summarize our experience of the application of internal rigid fixation with miniplate to treatment of mandibular fractures.methods a retrospective analyisis of clinical data of 67 cases,who had experienced the anatomic reduction and rigid fixation by using miniplate.with the help of maxillomandibular distraction pre operation and post operation and temporary maxillomandibular fixation during operation,the fracture bones were smoothly reduced and fixed.results clinical and radiographic examination showed that all cases gained good clinical results and precise anatomic alignment of fracture postoperatively without infection,malocclusion,bone malunion or other complications.conclusion mocortical miniplate fixation of the mandible is a reliable and effective techinique providing rigid fixation and an ideal modality for the treatment of mandibular fractures.combined with maxillomandibular fixation.

对67例下颌骨骨折患者的临床资料进行回顾总结，所有患者应用小型接骨板行坚固内固定治疗。其中7例颏部骨折，12例颏旁骨折，16例颏孔区骨折，9例体部多发性骨折，5例体部粉碎性骨折；18例合并其他部位骨折。所有患者术前经临床检查和影像学检查明确骨折的位置和骨折线的数目后，分段牙弓夹板结扎、颌间弹性牵引，使移位的骨折段逐渐复位；术中经口内切开复位、细钢丝颌间结扎、小型接骨板坚固内固定；术后行临床检查和影像学复查，必要时颌间弹性牵引7～10 d。结果所有患者手术切口ⅰ期愈合，治疗效果满意；临床检查所有患者牙合关系良好、面部对称；影像学复查证实骨折线对位良好。结论经口内切开小型接骨板坚固内固定辅以颌间固定治疗下颌骨骨折效果可靠，术后并发症少，是一种理想的手术方法。

Methods The design of burn scar flaps in tendo calcaneus was improved. In virtue of accessary transverse incision, ankle joints were reposited, without incision or free liberation of the internal side's scar flap.Results Improved scar flaps in tendo calcaneus met the need of ankle joints' functional reposition with an additional benefit that internal scar flaps were not prone to necrosis.

对跟腱瘢痕瓣进行改良设计，不切开内侧瓣内缘切口，内侧瘢痕瓣不游离，借助辅助横切口，将踝关节复位，同时观察早期烧伤创面的不同处理方法和伤后至手术时间的长短对功能复位的影响。

Adductor tenotomy,closed reduction and frog type plaster immobilization process is a effective way to treat children with DDH between 6～36 months old.

内收肌切断、手法闭合复位、改良蛙式石膏固定方法对6～36个月发育性髋脱位患者是一种有效的治疗方法，能很好的降低股骨头缺血性坏死的发生率，复位前髋臼指数值的大小与股骨头缺血性坏死的发生关系不大，但大于2 cm的高度脱位是并发股骨头缺血性坏死的重要因素之一。

In the fourth chapter and the fifth chapter, the article designed the front-end, including the power generating circuits, the clock generating circuits, the modulation/ demodulation circuits, and the voltage comparator. All the circuits were simulated and proved to work correctly. Finally the article designed layout of the front-end.

Results The rupture of posterior capsule, broken ciliary zonule, prolapse of vitreous during surgery trauma after surgery, type and material of intraocular lens were mainly causes of posterior chamber IOL dislocation. Pupillary dilatation with 1% tropicamide was achieved on 2 of 23eyes, Simple-replace of the IOL was performed succesfully on 10 eyes, anterior IOLs were implanted on 4 eyes, posterior IOLs were implanted on 4 eyes, and the IOL was removed on 3 eye.

结果 手术中后囊膜破裂、悬韧带离断、玻璃体脱出、手术后外伤及人工晶状体的材料和类型是后房型人工晶状体脱位的主要原因。23眼中2眼用1%托吡卡胺扩瞳后自行复位；10眼单纯手术复位成功；4眼更换前房型人工晶状体；4眼更换后房型人工晶状体；3眼取出人工晶状体后未再植入。
