The determination of skeletal age in young children is useful in predicting eventual leg length discrepancies, but underreading of skeletal age may result in predicting the ultimate leg length to be much longer than it actually will be, with a correspondingly larger discrepancy as well. We evaluated 100 hand/wrist radiographs of 45 children aged between 14 months and 9.8 years. Separate readings were taken of the distal radius and ulna, the carpal bones, and the metacarpals and phalanges. The discrepancy between bone ages and chronologic age was significantly different between regions of the hand and between sexes. When determining bone age in children under age 10 years, care should be taken to consider the entire hand, perhaps with less emphasis on the carpal bones.
幼儿骨骼年龄的测定有助于预测最终的腿长差异，但骨骼年龄判读不足可能会导致预测的最终腿长比实际腿长长得多，相应地差异也会更大。我们评估了45名年龄在14个月至9.8岁之间儿童的100张手部/腕部X光片。分别对桡骨远端和尺骨远端、腕骨以及掌骨和指骨进行判读。手部不同区域以及不同性别之间，骨龄与实际年龄的差异显著不同。在确定10岁以下儿童的骨龄时，应注意考虑整个手部，或许可减少对腕骨的重视。
