摘要
有关骨化方面的资料,我国尚缺系统的调查,文献中只查到山东医学院学报中刊登的一篇^([1])。但收集例数较少,不能以此确定骨化年龄标准,此外尚未查到其他有关国人骨化方面的资料。数十年来的教学及临床方面的应用,都不得不采用外国人的材料,由于生活习惯和营养条件的不同,这些材料是否符合我国实际,不无可疑。
A radiographical investigation on the time of appearance of ossification center andunion of epiphyses to the shaft of bones of hand and wrist was carried out in 1,890normal and healthy children(960 males and 924 females)in Shanghai.They weredivided into 22 age groups,ranging from new born,3 months,6 months,1 year,2 yearsand then yearly up to 18 years of age.Both hands and wrists were radiographed.The result is as follows:The ossification centers of the carpal bones appear in the following order:os capita-tum;os hematum;epiphysis of ulna;os triquetrum;os lunatum;os trapezium;os trape-zoideum;os scaphoideum,epiphysis of radius and os pisiforme.The appearance of the ossification centers and fusion of the opiphyses of the bonesof hand and wrist in the females occurs 1--2 years earlier than the males.The symmetrical appearance of the ossification centers of bones of both hands andwrists occurs in 56.5%and asymmetrical ones in 43.5%.Fusion of epiphyses of bones of both hands and wrists takes place symmetrically orsimultaneously at a higher ratio(78.8%).A standard type of ossification and maturation of bones of hand and wrist togetherwith drawings has been proposed for each age group.
