骨质由骨组织构成,分为骨密质和骨松质。骨松质结构疏松呈海绵状,由不规则的骨小梁排列而成,填充于骨的内部。目前针对各种临床和非临床干预下股骨头骨松质结构改变的研究较为多见,大多集中在股骨头骨松质的骨组织形态计量学研究,研究方法有股骨头切片法、微CT扫描及树脂包埋体视显微观察法,多采用兔作为实验对象[1,2]。兔的股骨头较大,在对其骨松质的实验研究中操作容易,各种研究方法易于实现,但也有其缺点,比如不适于运动模型的建立。大鼠是
Bone is composed of bone tissue, divided into bone cortex and cancellous bone. Loose spongy structure spongy sponge, arranged by irregular trabecular bone, filled in the interior of the bone. At present, the studies on the changes of the cancellous structure of the femoral skull under various clinical and nonclinical interventions are more common, most of which focus on the bone histomorphometry of femoral skull spondylolysis. The research methods include femoral head biopsy, micro-CT scanning and resin Embedding body microscopic observation method, the use of rabbits as experimental subjects [1,2]. Rabbit femoral head larger, easy to operate in the experimental study of its cancellous bone, a variety of research methods easy to implement, but also has its drawbacks, such as not suitable for the establishment of exercise model.
