The purpose of this study is to determine the normal ranges of radioulnar (i.e. medial-lateral) finger deviations during growth. We retrospectively measured radioulnar interphalangeal joint angles in 6236 properly aligned thumbs and fingers in trauma radiographs of 4720 patients aged 0 to 19 years. The mean interphalangeal joint angle of the thumb was 0.2° (standard deviation 1.5°). The average proximal interphalangeal joint angles were ulnar deviation of 2.5° (1.7°) for the index, ulnar deviation 1.7° (1.5°) for the middle, radial deviation 1.3° (1.8°) for the ring, radial deviation 2.0° (2.8°) for the little fingers. The distal interphalangeal joint angles were ulnar deviation of 2.5° (1.7°), ulnar deviation 2.1° (1.7°), radial deviation 2.1° (1.7°), radial deviation 5.1° (2.8°) from index to the little fingers. Thumbs were typically straight, whereas the index and middle fingers deviated ulnarly, and ring and little fingers radially. There were no relevant differences in sex or laterality.
本研究旨在确定生长过程中桡侧（即内外侧）手指偏斜的正常范围。我们回顾性地测量了 4720 名 0 至 19 岁患者创伤 X 线片中 6236 个正确对齐的拇指和手指的桡尺侧掌指关节角度。拇指掌指关节角度的平均值为 0.2°（标准差 1.5°）。平均近节指骨间关节角度为：示指尺侧偏斜 2.5°（1.7°），中指尺侧偏斜 1.7°（1.5°），环指桡侧偏斜 1.3°（1.8°），小指桡侧偏斜 2.0°（2.8°）。远节指骨间关节角度为：示指尺侧偏斜 2.5°（1.7°），中指尺侧偏斜 2.1°（1.7°），环指桡侧偏斜 2.1°（1.7°），小指桡侧偏斜 5.1°（2.8°）。拇指通常是直的，而示指和中指尺侧偏斜，环指和小指桡侧偏斜。性别或侧别无明显差异。
