目的　探讨骨折端受力、肌肉动力、骨痂密度与骨折愈合的关系。方法　通过传感器电测技术与X线灰度分析的方法,从三个方面对骨折愈合的应力适应性进行了研究:①分别对14只1岁龄山羊进行了断端受力与骨折愈合的关系的研究;②对10只健康成年家兔进行了肌肉动力与骨折愈合的关系的研究;③对56只健康成年家兔进行了骨痂密度与骨折愈合的关系的研究。结果与结论　①理想的骨折愈合与最佳的应力状态相适应;②肌肉动力是应力适应的反馈调节因素;③骨痂密度是应力适应的反馈结果。

Objective To explore the relationship between local stress status,muscular motivation,callus density and fracture healing.Methods　Stress adaptability of fracture healing was studied from three respects:1.the relationship between fracture local stress and fracture healing was studied in 14 one year old goats;2.the relationship between muscular motivation and fracture healing was studied in 10 health adult rabbits and 3.the relationship between callus density and fracture healing was studied in 56 healthy adult rabbits.Electric transducer technique and X-ray densitometry method were used in all the three groups of animals.Results and Conclusion　1.Ideal fracture healing should be adapted to the best stress status;2.Muscular motivation is the biofeedback regulation factor of stress adaptability of fracture healing;3.The density of callus is the result of biofeedback of stress adaptability of fracture healing.
