Abstract: Abstract:Rabbit is a commonly used experimental animal model for necrosis of the femoral head, but there is currently a lack of feasible and standardized injection methods for rabbit hip joint injection. Different from the traditional groin approach, this study was based on animal experiments. According to the anatomical characteristics of rabbits, this study retracted the hip joint to extend the joint space, accurately positioned, and explored a new method of injection and administration in the hip joint cavity of rabbits from the dorsal approach to avoid nerves and blood vessels. The result showed that this method was simple and convenient, and the drug can be smoothly injected into the rabbit hip joint cavity in strict accordance with the operation steps, with high safety and feasibility. This study provides a feasible and standardized operation process for rabbit hip joint injection in animal experiment, and the technical reference for the development of animal experiment.

摘要： 摘要:兔为股骨头坏死常用的实验动物模型,但目前缺少可行且规范的兔髋关节腔注射给药方法。 与传统腹股沟入路不同,本研究在动物实验基础之上,根据兔的解剖特征,内收髋关节以扩大关节间隙,精准定位,从背侧入路,避开神经和血管,探索了一种新的兔髋关节腔注射给药方法。 结果表明,该方法操作简便,严格按照操作步骤即可将药物顺利注入兔髋关节腔,安全性及可行性高。 本研究为动物实验中兔髋关节腔注射提供了可行且规范化的操作流程,为动物实验的开展提供了参考。
