摘　　要：目的　探讨距骨的形成及各个不同发育阶段的形态、结构和解剖特点。方法　出生前、后至正常成人 1795例右足侧位X线照片 ,其中男 917例 ,女 878例 ,1岁一个年龄组 ,每组 30～ 60例。结果　距骨原发骨化形态 ,从圆形到椭圆形 ,逐渐呈哑铃状外观。出生至 1岁 ,距骨生长速度增快 ;7岁时 ,距骨体部的增长加快 ,各骨性关节面和骨性突起相继出现。男 14岁 ,女 12岁以后 ,距骨的生长基本停止。Objective To investigate the formation,shapes,structures and anatomical features of the talus in different growth periods.Methods The shape growth of the talar was observed with lateral radiographs of the right foot from prenatal or postnatal to adults in 1795 cases(male 917,female 878,one group per year,every group 30～60 cases).Results The primary ossification shape of the talus manifested from roundness to ellipse and presented dumbbell appearances gradually.The growth speed of the talus increased rapidly from postnatal to 1 years old.The growth of the talar body increased rapidly up to 7 years old,and bone joint surface and protrude appeared one after the other.The growth of the talus stopped basicall after male 14 and female 12 years old.Conclusion The talar growth characteristics can be applyied to the judge of skeletal age and the diagnosis of the talar congenital and endemic diseases.
