The purpose of this investigation was to determine the effectiveness of commercially available wrist guards in preventing wrist fractures. Forty arms were harvested from 20 cadaveric specimens. The forearms from each cadaver, one with a wrist guard and one without a wrist guard, were then fractured using an instron Servohydraulic Material Testing System. The group of forearms tested to failure without wrist guards failed at an average force of 2245 N, while the group tested with wrist guards fractured at an average force of 2285 N, revealing no statistical difference. Similarly, observed fracture patterns were not noted to be different in the two groups. The in-line skating wrist guards tested were not effective in preventing wrist fractures under the experimental conditions of our study.
本研究的目的是确定市售护腕在预防腕部骨折方面的有效性。从20个尸体标本上取下40只手臂。然后使用英斯特朗伺服液压材料测试系统将每个尸体的前臂，一只佩戴护腕，另一只不佩戴护腕，造成骨折。未佩戴护腕测试至失效的前臂组平均在2245 N的力下失效，而佩戴护腕测试的组平均在2285 N的力下骨折，未显示出统计学差异。同样，两组中观察到的骨折模式也没有差异。在我们研究的实验条件下，测试的直排轮滑护腕在预防腕部骨折方面无效。
