摘　　要：本文论述了骨折外固定或内固定中存在的“应力保护”对骨折愈合的影响及其防止措施。骨组织的代谢、修复与重建需要一定的生理应力,这种应力是一种生物力学信号,有利于骨组织的修复与重建。骨折的固定如过分地阻止了这种生理应力就造成“应力保护”,不利于骨折愈合。认为在骨折固定中既要使断端保持稳定,又要允许一定的生理应力存在。认为内外固定治疗骨折的观点受到了挑战,研制柔软的固定材料以避免固定造成的“应力保护”是骨科固定发展的方向。The auther discusses the influence of stress-protection on fracture union and its protective method. The metabolism, healing and remoding of osteo-tissue need some physiologic stress. This kind of stress serves as a biomechanical signal and can promote the healing and remoding of osteo-tissue. If the fracture fixation over-protects this physiologic stress, it produces stressprotection which is harmful to the fracture union. So it is necessary not only to keep the fracture's fragments stable, but also to maintain some physiologic stresses in the fracture treatment. It's important to find out some flexible fixation materials and to avoid stress-protection in the development of orthopeadics.
