有读者问及某些比赛测骨龄是怎么回事,其实,人的年龄有两种,一种为日历年龄,即从出生年月起推算出来的年龄;另一种为生物年龄,即骨骼年龄,简称骨龄。它是以骨成熟度来描述儿童发育状况的指标,这是不易改动的。其解剖学定义为骨骺及小骨骨化中心出现的年龄和骨骺与骨干愈合的年龄。 我国已于近年研究制定了中国人手腕骨的发育评价标准作为骨龄的评价标准。用骨龄可将发育类型分为三组:骨龄减生活年龄之差在±1岁之内为发育一般组;骨龄大于生活年龄1岁以上为发育提前或早熟组;骨龄小于生活年龄1岁以上为发育延迟或晚熟组。相比生活年龄,骨龄更能反映儿童的生长发育状况,所以目前人们比较重视骨龄的研究与应用。
Some readers asked some of the game measured bone age is how the matter, in fact, there are two kinds of human age, one for the calendar age, that is estimated from the date of birth age; the other is the biological age, the skeletal age , Referred to as bone age. It is an indicator of bone maturity to describe the state of child development, which is not easy to change. Its anatomy is defined as the age at which the epiphysis and the ossification center appear and the age at which the epiphysis and the bone are healed. In recent years, China has developed a Chinese wrist evaluation of the development of bone as the evaluation criteria for bone age. Bone age can be divided into three types of developmental types: the difference between the age of bone less life within ± 1 years of development for the general group; bone age greater than the age of 1 years of age for the development of early or precocious; bone age less than 1 year of age of life Delayed or late development of late group. Compared to the age of life, bone age can better reflect the growth and development of children, so people pay more attention to bone age research and application.
