【摘要】目的：探讨不同固定方式治疗小儿伸直性肱骨髁上骨折的临床疗效。方法：回顾性分析2013年2月-2014年2月在我院进行治疗的48例小儿伸直型肱骨髁骨折患者的临床资料，根据固定方式将48例患者分成两组，克氏针组与夹板组，每组24例，克氏针组采取闭合复位后经皮克氏针固定，夹板组采取手法复位后杉树皮小夹板外固定，比较两组患者手术后骨折移位情况， 3个月后肢体功能活动情况及术后并发症发生率。结果：克氏针组无移位的发生率明显大于夹板组(P<0.01),差异有统计学意义。而夹板组的轻度移位，McIntyreⅢa ，McIntyreⅢb的发生率明显高于克氏针组(P<0.01),差异有统计学意义。克氏针组的优良例数明显高于对照组(P<0.01),有统计学意义。克氏针组患者术后并发症发生率明显低于对照组（P<0.01),有统计学意义.结论：克氏针固定术治疗小儿伸直型肱骨髁骨折具有术后移位少，功能恢复好，并发症发生率低等特点，故在小儿伸直型骨髁骨折治疗过程中应优先选择。
Abstract Objective: To investigate the clinical effect of different fixation method in treating pediatric extension-type supracondylar fracture of humerus. Methods: 48 cases of pediatric extension-type supracondylar fracture of humerus in our hospital from February 2013 to February 2014 were selected and they were divided into K-wire group and splint group, 24 cases in each group. K-wire group was given closed reduction and percutaneous K-wires fixation, splint group was given maneuver reposition and external fixation of small splints. Compared the fracture displacement situation, motor function of limbs after 3 months, postoperative morbidity rate of the two groups. Results: Occurrence rate of fracture displacement of K-wire group was obviously larger than splint group (P<0.01), the difference was statistically significant. Mild displacement, McIntyreⅢa and McIntyreⅢb occurrence rate of splint group was obviously higher than K-wire group (P<0.01), the difference was statistically significant. Excellent cases of K-wire group was obviously higher than control group (P<0.01), the difference was statistically significant. Adverse reaction rate of K-wire group was obviously lower than control group(P<0.01), the difference was statistically significant. Conclusion: K-wire fixation in treating pediatric extension-type supracondylar fracture of humerus has mild displacement, quicker function recovery, lower complication incidence rate and should be chosen preferentially.
