【Abstract】 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.更多还原
