简介:客观;为了评估临床的申请并且在皮肤上讨论反向的背面的掌部的拍动和它的复合拍动的起作用的指示,hand.Methods背叛:从1990~2003,我们使用了反向的背面的掌部的拍动和它的复合拍动在122种情况中修理手指的软织物缺点,它与腱接枝,神经接枝或骨头接枝包括了反向的掌部的拍动的90个盒子和它的复合拍动的32个盒子。基于后续观察,我们分析了在比较tocontralateral的掌部的拍动和它的复合拍动,手术后的轮廓,拍动颜色和质地回顾地摸的颠倒的指示。结果:在122个盒子的系列,熬过的拍动和施主地点缺点直接被关上。后续时期从1-12年。拍动和它的复合拍动的Thepostoperative轮廓,颜色和质地类似于正常手指的那些,尽管线性疤留下了。根据感觉恢复的标准(英国医药研究委员会,BMRC),拍动的感觉功能在操作以后恢复了S31年。在有拍动与腱接枝对待的腱缺点的10种情况中,手指的屈曲扩展的功能用全部的活跃运动的测量的方法与相反地侧面的手指相比恢复了50%-75%。在有不属于工会的phalangeal或拍动与骨头接枝对待的骨头缺点的7种情况中,联合为3months.Conclusions发生在操作以后:到有骨头或腱暴露的手指上的软织物缺点,反向的掌部的拍动和它的复合拍动是为修理的一种更好的选择。修理的范围直到手指的远侧的interphalangeal关节。第二根背面的掌部的动脉象脉管的小花梗的选择更一致、更大,与另外的背面的掌部的动脉比较。手术后的拍动颜色和质地类似于正常手指。
简介:讨论联合外部fixator和皮肤拍动调换的效果在上的目的暴露并且不属于工会的骨头。开的骨折在1998年3月的经期期间在我们的医院里对待到2008年6月的感染的不属于工会、暴露的骨头列在后面的12个盒子的数据被分析的方法。有10个男病人,2个女病人,其变老在19-52年之间并且平均28年。有10胫骨的破裂和2大腿骨的破裂。疾病的功课与19个月的吝啬的时期持续了12-39月。所有盒子被联合外部fixator和皮肤拍动调换对待。结果主要愈合在10种情况中被完成并且推迟在胫骨由于软织物缺点和因此本地的拍动调换在被暴露的2种情况中愈合被执行。所有12个盒子与8个月的平均时间在操作以后在6-12月以内有多骨的联合。他们被跟随在上面为1-3,年和所有破裂愈合了在上面与好功能和没有感染复发。联合外部fixator和皮肤拍动调换治疗在对待上看了最佳的效果的结论感染了,暴露并且不属于工会的骨头
