Laboratory tests were carried out on cadaver animal bones to evaluate the thermal effect of inserting K-wires with a pneumatic hammer as compared to drilling. The mean maximum bone temperature 0.5 mm from the K-wires was 34 (22-72) degrees C using the hammer and 54 (19-100) degrees C for drilling, 1.0 mm from the K-wire the mean maximum temperature was 31 (19-52) degrees C for hammering and 47 (17-91) degrees C for drilling. The mean time for the temperature exposure in the cases of drilling was 50 s and for hammering 41 s. The hammering device may reduce the risk of heat-induced injury.
在尸体动物骨上进行了实验室测试，以评估与钻孔相比，使用气锤插入克氏针的热效应。距离克氏针0.5毫米处，使用气锤时骨的平均最高温度为34（22 - 72）摄氏度，钻孔时为54（19 - 100）摄氏度；距离克氏针1.0毫米处，锤击时平均最高温度为31（19 - 52）摄氏度，钻孔时为47（17 - 91）摄氏度。钻孔情况下温度暴露的平均时间为50秒，锤击为41秒。锤击装置可能会降低热致损伤的风险。
