‘骨龄是骨骼年龄的简称,医学上是通过对骨成熟程度的测定来确定的。人身上有206块骨头,每块骨头都有各自的形态结构、功能和神经血管,有着生长、发育、修复、愈合及再生的能力。借助关节,骨连接形成骨骼,以维持体形、支持体重,保护和支持脏器。骨骼还供肌肉附着,成为人体的运动器官,在身体的各种运动中起杠杆作用骨髓具有造血功能,是人体重要的免疫器官之一……可见,骨骼就像是一部精密而神奇的机器,参与着人体的一切活动。骨的发育过程具有连续性和阶段性,各阶段具有一定的形态特点,能在X光片上表现为一定的征象,称之为成熟标志。目前,骨龄测定已在医学、体育学、法学和人类学研究等方面广泛应用,通常采用的最简捷方法,就是拍摄手腕部骨骼的X光片,来研究其发育程度。
’Bone age is the abbreviation of bone age, medically determined by the degree of bone maturity. There are 206 bones in the body. Each bones has its own morphological structure, function and nerve blood vessels, with the ability to grow, develop, repair, heal and regenerate. With the help of joints, the bones are connected to form the skeleton to maintain body shape, support body weight and protect and support organs. Bone also for muscle attachment, as the human body’s organs of movement in the body’s various movements play a lever role of bone marrow hematopoietic function, is one of the body’s important immune organs ... Visible, the bones is like a sophisticated and magical machine , Involved in all activities of the human body. Bone development process has a continuity and stage, each stage has a certain morphological characteristics, can be displayed on the X-ray film for certain signs, known as a sign of maturation. Currently, bone age determination has been widely used in medical, physical education, law and anthropology research. The simplest method usually used is to study the development of the wrist by analyzing the X-ray of the bones of the wrist.
