了解骨骼如何响应导致失败（骨折）的负载可以帮助理解导致损伤的力。图19 - 1显示了在急诊室和骨科诊所中常见的损伤。这种损伤的患者通常会说是在跌倒时发生的。但是，如果你问病人，“你打了谁？"，病人不好意思地看着你，说他打架了，或者生气了，撞到了墙上。X光片显示了通常所说的拳击手骨折。它最常见的结果是用拳头击打某人或某物。我们知道这种损伤不是在跌倒时发生的，因为跌倒时的正常反应是张开手，摔倒在张开的手上，导致手腕或肘部骨折，这不是图19 - 1所示的损伤。因此，了解肢体损伤的生物力学有助于确定导致损伤的创伤。
An understanding of how bones respond to loads that cause failure (fractures) can help in understanding the forces that cause the damage. Figure 19.1 shows an injury not uncommonly seen in emergency rooms and orthopedic offices. It is not uncommon for a patient with this injury to state that it happened during a fall. However, if you asks the patient, “Whom did you hit?”, the patient looks at you sheepishly and says that he was in a fight or got angry and hit a wall. The x-ray demonstrates what is commonly known as a boxer’s fracture. It most commonly results from hitting someone or something with a closed fist. We know this injury did not occur in a fall because the normal reaction when falling is to open one’s hand and fall on the open hand, sustaining a wrist or elbow fractures, which is not the injury depicted in Figure 19.1. Thus, an understanding of the biomechanics of extremity injuries helps in determining the trauma that caused an injury.
