摘要
Abstract
It is necessary to realize the mechanical properties of the C2 -3 、T10 - 11、 L3 -4 in order to prevent and treat the herniated disk. So we test the bent experiment of the C2 -3、T10 -11、L3 -4 taken from the fresh dead bodies and provide biological mechanical data for clinic. The experimental specimens are taken from male fresh corpses of normal people, 20 -30 years old respectively. The C1 - S1 spine specimens are taken from the bodies within one hour after death, and the C2 -3 、T10 - 11 、L3 -4 intervertebral discs and vertebral bodies are cut by line cutting, each thirteen samples. Do the test on the Japanese shimadzu electronic universal testing aircraft, the experimental speed is 5mm/min, obtain the bending mechanics performance index of maximum load、 maximum bending moment、 maximum stress of the C2 - 3、 T10 - 11、 L3 - 4 groups. The maximum load and maximum bending moment of C2- 3group is less than the T10 - 11 group and the L3 -4 group with a significant difference (p ＜ 0.05 ). The maximum stress of C2 - 3 group is less than T10 - 11 group, with a significant difference (p ＜ 0.05 ). The maximum stress of L3 -4 group is greater than the T10- 11 group and the C2- 3 group with a significant difference (p ＜ 0.05 ).关键词
