Using both clinical and laboratory studies we investigated whether predrilling before insertion of external fixation pins is necessary for use in treating distal radius fractures. Our clinical study included 50 consecutive external fixators (4.0- and 2.5-mm pins) using 100 predrilled and 100 direct-drilled pins placed in a randomized manner. There was no increased incidence of pin track infection or other pin problem with the direct-drilled technique. There were, however, significantly elevated temperatures with the direct-drilled technique. We therefore recommend predrilling even though the temperature differences in this bone with this fixator were not clinically evident.
我们通过临床和实验室研究，调查了在治疗桡骨远端骨折时，插入外固定针之前预先钻孔是否必要。我们的临床研究纳入了50例连续使用外固定器（4.0毫米和2.5毫米的针）的病例，以随机方式置入100枚预先钻孔的针和100枚直接钻孔的针。直接钻孔技术并未增加针道感染或其他针相关问题的发生率。然而，直接钻孔技术会使温度显著升高。因此，尽管使用该固定器时这种骨内的温度差异在临床上并不明显，我们仍建议预先钻孔。
