远红外陶瓷对家兔实验性骨折愈合的影响

目的探索促进骨折愈合的方式方法.方法采用中国杂交兔80只,用手锯造成兔双侧桡骨中段3mm标准骨缺损,随机分成两组,分别用远红外陶瓷高分子绷带和普通高分子绷带固定双前肢,于3,4,5,6周分别摄片、做组织切片、力学测试和电镜观察.结果远红外陶瓷对家兔骨折愈合有促进作用(P<0.05).结论远红外陶瓷加入高分子绷带中用于骨折固定,既有外固定作用,又有加速骨折愈合的促进作用,为骨折愈合提供了一种新的治疗方法.

Far-infrared pottery macromolecule bandage for fracture healing of rabbits experimentally

Objective To explore the optimal method of promoting fracture healing.Methods Under aseptic operation, the medium of both radii in 80 rabbits was formed 3 mm defect. Then,the rabbits were randomly divided into two groups:A group rabbits were fixated by far-infrared pottery macromolecule bandage(SIO 2IMgo,AL 2O 3 etc) on both radii.B group were treated by common macromolecule bandage.The rabbits were sacrificed at 3rd,4th,5th and 6th week after surgery. Specimens were obtained from the fracture site and evaluated with x-ray film, electron microscopic, pathology and mechanics measurement. Results It was found that far-infrared pottery macromolecule bandage on fracture healing had better promoting effect than that of common macromolecule bandage (P<0.05).The effect accelerated at the 4-5th week after treatment. Conclusion Far-infrared pottery incorporated with macromolecule bandage has both external fixation and promoting fracture healing for fracture. Therefore, it provides a new therapy for promoting fracture healing.
