Abstract

Standard growth of lower extremities in children and adolescents in Hong Kong

We aimed to generate growth charts of lower-limb long bones to serve as our local reference for the comparison and prediction of bone length with respect to age. In patients with leg-length discrepancy, longitudinal measurements of femur and tibia of the unaffected leg were taken and charted against bone age and chronological age. Altogether, 123 femur and tibia lengths were measured in 10 Chinese patients. The bone age ranged from 2.90 to 19.00 years old, and chronological age ranged from 1.25 to 16.67 years old. In general, bone length and age held a quadratic relationship. There was no significant difference in bone length estimation with respect to whether the bone age or chronological age was used. A highly significant statistical correlation (p=0.969, at an 0.01 level of significance) was found between bone age and chronological age.

香港兒童及青少年下肢骨骼生長標準圖

高希雅、李閏海

本研究旨在制定香港兒童及青少年下肢的骨骼生長標準圖,作本地比較及估算骨骼生長速度的參考資料。我們在下肢不等的病者中,取其非患側股骨和脛骨的長度,與骨齡和時序年齡相對照,繪出相關的標準圖。本研究共納入10名下肢不等的本地病者 (骨2.9-19.00歲;時序年1.25-16.67歲),共量度了123例股骨及脛骨長度。結果顯示骨長與年齡呈非常顯著的二元次曲線關係 (p= 0.969),而骨長估算誤差跟年齡類別無顯著關係。
