Objective: Using the treatment of low temperature and frozen in liquid nitrogen from the 6-week- old normal Wistar rat femur bone in experimental 20 min upper intercept, rapid recover bone block temperature from the conventional disinfection, after reset, to observe the healing effect of nitrogen on Wistar rats femoral oblique fracture. Methods: Ten 6-week-old Wistar rats were randomly divided into two groups, group A had five Wistar rats that was blank control group, group B was an experimental group. By routine aseptic operation treatment of two groups of Wistar rat right hind femur, A group operation manufacturing oblique fracture model out fracture specimens were immersed in saline at 20 minutes after routine disinfection after the reduction, B group operation manufacturing oblique fracture specimens were frozen in liquid nitrogen removal at low temperature 20 minutes rapidly after 27˚C of sterile saline after rewarming and after routine disinfection fracture reduction model. Results: Experimental study found that the experimental group, femoral specimens were reimplanted into Wistar rats, a few weeks after the observation of normal growth, the growth of the fracture line intact, and the blank control group growth recovery after statistical analysis; there was no significant difference or statistical significance (P > 0.05). Conclusion: Through the experimental study of liquid nitrogen freezing technology has no effect on the Wistar rats of normal bone fracture healing of normal growth, the future will be applied to the clinical treatment.
