Abstract

The effectiveness of various therapeutic methods on bone fracture has been demonstrated in several studies. In the present study, we tried to evaluate the effect of local low-magnitude, high-frequency vibration (LMHFV) on rat tibia fracture in comparison with pulsed electromagnetic fields (PEMF) during the healing process. Mid-diaphysis tibiae fractures were induced in 30 Sprague-Dawley rats. The rats were assigned into groups such as control (CONT), LMHFV (15 min/day, 7 days/week), and PEMF (3.5 h/day, 7 days/week) for a three-week treatment. Nothing was applied to control group. Radiographs, serum osteocalcin levels, and stereological bone analyses of the three groups were compared. The X-rays of tibiae were taken 21 days after the end of the healing process. PEMF and LMHFV groups had more callus formation when compared to CONT group; however, the difference was not statistically significant (P = 0.375). Serum osteocalcin levels were elevated in the experimental groups compared to CONT (P ≤ 0.001). Stereological tests also showed higher osteogenic results in experimental groups, especially in LMHFV group. The results of the present study suggest that application of direct local LMHFV on fracture has promoted bone formation, showing great potential in improving fracture outcome.

摘要

多项研究已证实了各种治疗方法对骨折的有效性。在本研究中,我们试图评估局部低强度、高频振动(LMHFV)与脉冲电磁场(PEMF)相比,在大鼠胫骨骨折愈合过程中的作用。在30只Sprague-Dawley大鼠中诱导造成胫骨干中段骨折。将大鼠分为对照组(CONT)、LMHFV组(每天15分钟,每周7天)和PEMF组(每天3.5小时,每周7天)进行为期三周的治疗。对照组不施加任何处理。比较了三组的X线片、血清骨钙素水平和骨组织形态计量学分析结果。在愈合过程结束21天后拍摄胫骨X线片。与CONT组相比,PEMF组和LMHFV组有更多的骨痂形成;然而,差异无统计学意义(P = 0.375)。与CONT组相比,实验组血清骨钙素水平升高(P≤0.001)。骨组织形态计量学测试也显示实验组有更高的成骨效果,尤其是在LMHFV组。本研究结果表明,对骨折部位直接施加局部LMHFV可促进骨形成,在改善骨折愈合结果方面显示出巨大潜力。《生物电磁学》。2017年;38:339 - 348。©2017威利期刊公司。
