距骨临床X线测量

目的 研究距骨生长发育规律并建立出生后幼儿至成人正常距骨X线测量值。方法 对1765例正常儿童、青少年右足距骨X线照片进行测量。结果 两岁以前，距骨的生长速度最快，与体格发育(如体重、身高等)相一致。以后不出现明显的增长高峰。到青春发育期，距骨也不出现增长高峰。结论 X线测量值不但用于某些先天性或后天性疾病所致距骨形态改变的正常对照，而且也用于其他方面(如人类学、法医学)的研究。

RADIOGRAPHIC MEASUREMENTS OF TALUS

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).
