| 摘 要： | 背景:有些观点认为捆绑带的使用会影响骨折部位的血运甚至造成骨折延迟愈合与骨折不愈合.目的:观察3种不同束缚压力捆绑带对骨折动物模型骨痂形成及愈合的影响.方法:建立新西兰大白兔股骨干非负重骨折动物模型,髓内固定后随机分为3组,分别在骨折部位加用200,150,100 N束缚压力的捆绑带固定,术后2,4,6周观察骨痂形成及愈合.结果与结论:200 N压力组骨折固定牢固,但骨折断端外骨痂形成受限,无骨愈合,影响断端远期稳定性.100 N压力组早期骨折断端不稳定,虽不影响骨折愈合,但容易出现畸形愈合.150 N压力组压力适中,骨折固定与愈合均良好.提示在保持适当束缚压力的情况下,捆绑带可以有效维持骨折部位稳定,避免骨折移位或畸形愈合,保障骨折正常愈合,对骨折部位骨膜血运无异常影响,有助于促进骨折早期愈合.

| Abstract: | BACKGROUND:Some people believe that Cerclage band can influence the blood supply at fracture site leading to delayed healing and nonunion of fractures.OBJECTIVE:To observe the effects of Cerclage band with three different bound stresses on the callus formation and fracture healing in fracture animal models.METHODS:Femoral shaft fracture animal models of non-weight-bearing were established and divided into three groups.The cerclage band with three different bound stresses(200,150,100 N) was added at the frac... |
