目的:观察伤肢肌肉在电动刺激下被动收缩活动能否加速骨折愈合。

方法:家兔64只,造成右胫骨横断骨折,然后随机分为两组,一组为实验组,于选模后第3天开始给予伤肢电动刺激使其肌肉被动进行收缩活动；另一组不予任何刺激作为对照。两组动物于骨折后2、4、6、8周分批处死,进行X线片、生物力学、病理组织学对比观察。

结果:实验组动物骨折的愈合速度快于对照组,其伤肢抗折性能也优于对照组(P<005).

结论:伤肢肌肉被动收缩活动能促进家兔骨折愈合。

Morphology and Biomechanics Studies of Muscular Activity Accelerate Healing of Fracture on Rabbits Injury Limbs

Abstract:

Objective:To observe whether or not passive muscular contraction under electric stimulation in injury limbs can accelerate the healing of fracture.

Methods:64 rabbits of right tibia transverse fracture were chosen.The rabbits were divided into two groups randomly.In test group,the wound limbs accepted electric stimulation to produce passive muscular contraction,while in control group accepted nothing.The rabbits were killed separately on the end of the 2th,4th,6th and 8th week after the fracture had been made.The contrast study of the X ray,biomechanism and pathology had be done.

Results:The healing of fracture of test group is better than that of the control group.(P<0.05)

Conclusion:Passive muscular contraction in injury limbs can accelerate the healing of fracture.
