OBJECTIVE
To find a new reference for assessment of pediatric forearm radiographs besides the traditional RCL.
METHODS
RCLs were drawn on the anteroposterior (AP) and lateral radiographs of 170 normal pediatric forearms. Three lines were drawn on each radiograph: the first was drawn along the longitudinal center of the radial neck (N-line); the second, along the radial shaft (S-line); and the third, through the midpoints of the proximal and distal radial physes (P-line).
RESULTS
The P-line was least likely to miss the capitellum on both AP views and lateral views, and the P-line most frequently passed through the central third of the capitellum on both AP views and lateral views.
CONCLUSIONS
Our proposed radiocapitellar P-line was found to be much more reliable in younger children than traditional RCLs.
目的
除了传统的桡骨小头中心连线（RCL）外，寻找一种评估小儿前臂X线片的新参考方法。
方法
在170例正常小儿前臂的前后位（AP）和侧位X线片上绘制RCL。每张X线片上绘制三条线：第一条沿着桡骨颈的纵向中心绘制（N线）；第二条沿着桡骨干绘制（S线）；第三条通过桡骨近端和远端骨骺中点绘制（P线）。
结果
在AP位和侧位上，P线最不容易遗漏肱骨小头，且在AP位和侧位上，P线最常穿过肱骨小头的中央三分之一。
结论
我们提出的桡骨小头P线在年幼儿童中比传统的RCL可靠得多。
