Abstract:
L in ulna and radius.In other long bones.most cases are asymmetrical.This means that the side-difference has been existedduring the fetal life.2.The sex-difference is non-significant during the fetal lifeat the age before 35th week.3.It has been found that the growing speed of limblong bones are different during the different periods of fetal live.It is suggestedthat the growth of fetal limb long bones be divided into two stages:(1)12th-13thweek is a high-speed synchronism stage,the length increased fast and generally theupper limb bones are longer than the relevant lower l(?)mb bones;(2)19th-35thweek is a reduced-speed divergent stage,the growing speed decreased relatively,helower limb long bones are over the upper in length.
