文题释义:
脉冲电磁场:由美国著名矫形外科专家Bassett提出并成功地应用于临床治疗,有显著的治疗效果。其基本原理在于可变电磁场能诱发导体中的电压和电流。
森林图:是以统计指标和统计分析方法为基础,用数值运算结果绘制出的图型。它在平面直角坐标系中,以一条垂直的无效线(横坐标刻度为1或0)为中心,用平行于横轴的多条线段描述了每个被纳入研究的效应量和可信区间(confidence interval,CI),用一个棱形(或其它图形)描述了多个研究合并的效应量及可信区间。它非常简单和直观地描述了Meta分析的统计结果,是Meta分析中最常用的结果表达形式。
摘要
背景:
临床研究证实了低频脉冲电磁场除了用于骨折延迟愈合与骨不连外,对新鲜骨折、骨切除术及疲劳骨折的治疗也有显著疗效。
目的:系统评价低频脉冲电磁场促进骨愈合的临床疗效和安全性。
方法:通过检索中国学术期刊全文数据库(CNKI)、美国国立医学图书馆生物医学信息检索系统(PubMed)等数据库中1985年1月至2016 年5月有关低频脉冲电磁场促进骨折愈合的随机对照临床研究文献,对纳入文献进行资料提取、方法学质量评价,并采用 RevMan5 .1软件进行统计分析。
结果与结论:①有13篇文献符合纳入标准,共有1 244例患者,均为随机对照临床试验;②Meta分析结果显示:低频脉冲电磁场治疗组的总体有效率高于对照组的总体有效率;治疗组的骨折愈合时间显著低于对照组的骨折愈合时间;治疗组的骨密度显著高于对照组的骨密度;③结果说明,低频脉冲电磁场促进骨折愈合的总有效率较高,能显著缩短骨折愈合时间且安全性较高,但还需要大量Jadad法评分高的多中心、大样本量随机对照临床试验来进一步验证。

Abstract:

BACKGROUND: Low frequency-pulsed electromagnetic fields (LF-PEMFs) have been confirmed to not only treat delayed bone union or nonunion, but also be effective for fresh bone fractures, ostectomy and fatigue fractures.
OBJECTIVE: To systematically evaluate the efficacy and safety of LF-PEMFs for bone healing. 
METHODS: CNKI and PubMed databases were retrieved for the randomized controlled trials concerning LF-PEMFs promoting bone healing published from January 1985 to May 2016. Meta-analysis was conducted on RevMan 5.1 software after data management and quality assessment.
RESULTS AND CONCLUSION: Thirteen eligible literatures were enrolled, involving 1244 patients. Meta-analysis showed that the overall effectiveness and bone mineral density in the LF-PEMFs group were significantly higher than those in the control group. The healing time in the LF-PEMFs group was significantly shorter than that in the control group. These results suggest that LF-PEMFs show high efficacy and safety for bone healing, and also can markedly shorten the healing time. However, more high-quality multi-center, large-scale randomized controlled trials are still needed to testify all above conclusions.
