目的：本文测量国人改良腕高率和腕高指数。方法：按照Ｎａｔｒａｎ方法测量１００例正常人２００个腕关节的标准腕高率、改良腕高率、标准腕高指数及改良腕高指数。结果：国人标准腕高率为０．５４±０．０４２，标准腕高指数为１．００±０．０３４，改良腕高率为１．３４±０．０７６，改良腕高指数为１．００±０．０６１。结论：改良腕高率测量方法具有良好的稳定性、重复性、一致性、灵敏性、特异性和实用性，值得推荐。
Objective: This article measures the improvement of Chinese wrist rate and wrist high index. Methods: According to the Natran method, the standard wrist rate, wrist rate, standard wrist index and modified wrist high index were measured in 200 cases of normal wrist. Results: The standard Chinese wrist rate was 0.54 ± 0.042, the standard wrist high index was 1.00 ± 0.034, the modified wrist high rate was 1.34 ± 0.076 and the improved wrist high index was 1.00 ± 0.061. Conclusion: The modified wrist rate measurement method with good stability, repeatability, consistency, sensitivity, specificity and practicality, it is recommended.
