髋部护具是预防跌倒相关髋部骨折的一种很有前途的策略。然而，临床试验产生了相互矛盾的结果，部分原因是缺乏对测量和优化髋关节保护器生物力学性能的技术达成一致，这是临床试验的先决条件。2007年11月，国际髋关节保护器研究小组在哥本哈根召开会议，讨论髋关节保护器临床有效性的障碍。本文代表了该小组对评估髋关节保护器生物力学性能的推荐方法的循证共识声明。测试的主要结果应该是在模拟大转子坠落过程中施加于股骨颈的轴向压缩力峰值减少的百分比（与未填充的情况相比）。为了提供合理的结果，测试系统应准确模拟骨盆解剖，以及碰撞时的冲击速度（3.4 m/s）、骨盆刚度（可接受范围：39-55 kN/m）和身体有效质量（可接受范围：22-33 kg）。鉴于目前缺乏关于特定髋关节保护器临床疗效的明确证据，目前生物力学测试的主要价值是比较不同产品的保护价值，而不是拒绝或接受特定设备的市场使用。
Hip protectors represent a promising strategy for preventing fall-related hip fractures. However, clinical trials have yielded conflicting results due, in part, to lack of agreement on techniques for measuring and optimizing the biomechanical performance of hip protectors as a prerequisite to clinical trials. In November 2007, the International Hip Protector Research Group met in Copenhagen to address barriers to the clinical effectiveness of hip protectors. This paper represents an evidence-based consensus statement from the group on recommended methods for evaluating the biomechanical performance of hip protectors. The primary outcome of testing should be the percent reduction (compared with the unpadded condition) in peak value of the axial compressive force applied to the femoral neck during a simulated fall on the greater trochanter. To provide reasonable results, the test system should accurately simulate the pelvic anatomy, and the impact velocity (3.4 m/s), pelvic stiffness (acceptable range: 39–55 kN/m), and effective mass of the body (acceptable range: 22–33 kg) during impact. Given the current lack of clear evidence regarding the clinical efficacy of specific hip protectors, the primary value of biomechanical testing at present is to compare the protective value of different products, as opposed to rejecting or accepting specific devices for market use.
