ABSTRACT
Objective To investigate the rule of the talar growth and establish a normal radiographic measurement scale of the talus from postnatal infants to adults. Methods Radiographic measurements were performed with the lateral radiographs of right talus in 1*!765 normal cases(age 1 to 18). Results The talar growth velocity was the fastest before two years old.It was consistent with the development of physiques(e.g.height and weight),and then there was not a remarkable increase in the talar growth.At puberty,a temporal sudden increase was not found in the talus.Conclusion Radiographic measurements not only provide a normal contrast for the flats of the talus or the abnormal shapes caused by some congenital or acquired disease,but also was useful to the other subject(e.g.anthropology,forensic science).
