查询词典 distraction

Methods］When scoliosis of patients were corrected to a certain degree after three weeks of halo pelvic distraction, the most serious collapsed ribs of concave side of the curve underwent a transverse incision the cross ribs. A special rib bender was used to bend the exposed 3 to 6 ribs. The bent ribs were pulled up by double-stranded 10# thick silk which was extended out through the skin and fixed in the upright post of the instrument of Halo pelvic distraction with rubber membranes.

方法］颅盆牵引3周后，脊柱侧弯矫正到一定程度时，在侧弯凹侧肋骨塌陷最重的部位，与肋骨交叉作横切口，暴露3～6条肋骨，用特制的肋骨折弯器将肋骨折弯变圆，用10号双股粗丝线将每条肋骨提起，自皮肤穿出通过橡皮膜在颅盆装置的立柱上作牵引。

Distraction loads can not correct spinal rotatory deformity. Derotation can be achived by applying rotation forces. Improper distraction loads will lead to lumbar kyphosis.

单纯于脊柱凹侧施加撑开力作用可矫正该模型中脊柱冠状面的侧凸畸形，但是若是要将畸形彻底矫正，所需要施加的纵向撑开力有可能超出椎弓根或椎板的破坏载荷而导致椎弓的骨折。

Mandibular distraction osteogenesis perhaps causes a temporarily negative effect on the condyle, which will undergo a long remodification process to be resumed.2.1mmunohistochemical study of type I and III collagen in condyle in mandibular distraction osteogenesisResults: The expression of type I collagen increased more slowly.

犬双侧下颌骨牵张成骨中髁状突软骨Ⅰ、Ⅲ型胶原变化的研究第四军医大学硕士学位论文结果：犬躲状突软骨中1型胶原的表达增加缓慢，至牵张结束8周仍有超常水平；Ill型胶原的表达随时间的延长逐渐增加，至牵张结束4周达到顶峰，随后逐渐减弱。

RESULTS: Distraction osteogenesis implants contained intraoral or extraoral distraction device, which could be used for distraction of transport plate.

结果：牵张成骨植入物分为口内牵张器和口外牵张器，可进行转移盘的牵引。

METHODS: The 8 patients underwent mandibular distraction osteogenesis,and altogether 16 distractors were placed through extraoral or intraoral incisions for bilateral distraction. The distraction device proceeded at the rate of 1 to 1.5 mm per day and consolidated for 4 to 12 weeks.

8例患者均行牵引成骨技术牵引双侧下颌骨治疗，经口内或口外途径共安放16个牵引器，牵引速度1～1.5 mm/d，固定4～12周，随访2～18个月。

Differential expression of IGF-I in muscles of mastication during distraction osteogenesis of mandible in canine.This study was conducted to observe the expression of IGF-I in masseter and geniohyoid during distraction osteogenesis of mandible in canine through the immuno-histocytochemical method.

试验三犬下颌骨牵张成骨过程中咀嚼肌IGF.I的表达变化将所取标本进行免疫组化染色，检测犬下颌骨牵张成骨过程中嚼肌与颁舌骨肌中IGF.I表达的变化。

During the procedure of distraction, geniohyoid expressed hypertrophy and hyperplasia initially and then restore normal level after distraction, while masseters was influenced rarely.

结果发现在牵张过程中，颏舌骨肌先是发生再生与肥大，最终组织学形态恢复至牵张前的形态；而嚼肌受其影响不大，只是在牵张5天时有轻度的萎缩，可能与牵张过程中引起的干扰有关。

Results: During tibial metaphysis callotasis, the range of motion of knee decreased with distraction range of the limb. It was not significantly disordered in 10% distraction group, but it was significantly disordered when the distraction range was up to 20% tibial length.

结果：（1）胫骨干骺端截骨缓慢牵伸延长时，膝关节活动度随延长幅度增大而逐渐减小，当延长幅度低于10％时关节功能障碍尚不明显，但当延长幅度达20％以上时关节活动度出现显著性下降。

Objective: The purpose of this study is to establish a periosteal distraction model on rabbit mandiblar ramus, to observe the formation of newly formed bone and its structure in each phase after distraction of periostea, to observe the changes of periostea after being secondary to distraction forces, to investigate the possibility of osteogenesis by periosteal distraction in oral and maxillofacial region, and to study the possibility of a new restoration method of clincal alveolar and other bony defect.

目的：本研究在兔下颌升支建立骨膜牵张成骨模型，观察牵张骨膜后，在骨膜下新骨的形成，以及新骨在各个阶段的结构，同时观察了骨膜受到牵张力后的改变，研究骨膜牵张在口腔颌面部成骨的可能，为牙槽骨缺损及其他口腔颌面部骨组织缺损探讨新的重建方法。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.
