手法复位治疗36例儿童肱骨髁上骨折

儿童肱骨髁上骨折多见于儿童,成年和老年人亦可发生.是肘部最常见的损伤之一.约占全身骨折发生率的第三位,占肘部损伤发生率的39.74%.儿童肱骨髁上部位在结构上最为薄弱,为松质骨与骨皮质交界处.肘关节及侧副韧带相对比较坚固,故肘关节损伤时容易发生骨折不易发生脱位.根据暴力的形式及受伤时肘关节体位不同,可造成不同类型的髁上骨折.其中伸直尺偏型最多,发生率高达90%以上.此型骨折发生后,骨折远端向尺侧移位,尺侧骨皮质可有嵌压塌陷,骨膜多被剥离,桡侧骨膜多断裂,因此复位后骨折远端容易向尺侧再移位.即使达到解剖对位,也因尺侧骨皮质嵌压缺损而向尺侧偏移.故此型骨折肘内翻畸形的发生率极高.

The technique replacement treats 36 example child humerus supracondyloid bone fracture

The child humerus supracondyloid bone fracture sees much in the child,grown--up and the senior citizen also may occur. Is one of elbow department most common damages. Approximately composes whole body bone fracture formation rate third,accounts for the elbow department damage formation rate 39. 083 % child humerus supracondyloid spot to be weakest in the structure, for substantia spongiosa bone and bone cerebral cortex intersection point. Elbow joint and ligamenta collateralia relative quite firm, when the elbow ioint damages easy to have the bone fracture not not easily to have the dislocation. And is iniured according to the violence form when the elbow joint body posture is different,may create the different type the supracondyloid bone fracture. In which leaning extends the straightedge to be most,the formation rate reaches as high as above 90%. After this bone fracture occurs, the bone fracture far--end to ruler side shifting,the ruler side bone cerebral cortex may have inlays collapses by pressure falls,the periosteum many is stripped, oar side periosteum multi--breaks, after therefore repositions the bone fracture far--end again to shift easi- ly to the ruler side. Even if achieves the dissection to the position,but because also the ruler side bone cerebral cortex inlays presses the damage to the ruler side displacement. Therefore in the bone fracture elbow turns the abnormal formation rate to be extremely high.
