克氏针钻孔过程中的冷却并不总能有效防止热相关损伤。在本研究中，我们使用了人体体外模型，并比较了三种克氏针插入方法-钻孔和不冲洗以及气动锤击之间的温升、插入时间和拔出力。将45根克氏针置入15侧新鲜人尸掌骨内。所有三种插入方法均应用于每根掌骨。无冲洗钻孔导致温度升高67.25 +/- 5.4 ℃，冲洗钻孔（4.15 +/- 0.6 ℃）和气动锤击钻孔（31.52 +/- 3.4 ℃）的温度值明显较低。气动锤击的插入时间（47.63 +/- 8.8 s）显著低于无冲洗钻孔（263.16 +/- 36.5 s）和有冲洗钻孔（196.10 +/- 28.5 s）。钻孔（无冲洗）、钻孔（有冲洗）和气动锤击后的拔出力分别为39.85 +/- 4.1 N、57.81 +/- 6.5 N和62.23 +/- 6.7 N。气动锤击比不进行冲洗的钻孔要优越上级，尤其是在不可能进行冲洗的情况下。
Cooling during drilling Kirschner wires is not always effective in preventing thermal related damage. In this study, we used a human in vitro model and compared temperature elevation, insertion time, and extraction force between three Kirschner wire insertion methods-drilling with and without irrigation and pneumatic hammering. Forty five Kirschner wires were inserted into 15 fresh human cadaver metacarpals. All three insertion methods were applied in each metacarpal. Drilling without irrigation resulted in a temperature elevation of 67.25 +/- 5.4 degrees C with significantly lower values for drilling with irrigation (4.15 +/- 0.6 degrees C) and pneumatic hammering (31.52 +/- 3.4 degrees C). The insertion time for pneumatic hammering (47.63 +/- 8.8 s) was significantly lower compared to drilling without irrigation (263.16 +/- 36.5 s) and drilling with irrigation (196.10 +/- 28.5 s). Extraction forces after drilling without irrigation, drilling with irrigation, and pneumatic hammering were 39.85 +/- 4.1 N, 57.81 +/- 6.5 N, and 62.23 +/- 6.7 N, respectively. Pneumatic hammering is superior to drilling without irrigation, especially when irrigation is not possible.
