The occurrence of total hip impingement, whether or not accompanied by frank dislocation, holds substantial untoward clinical consequences, especially as less-forgiving advanced bearing implant designs come into ever more widespread use. Biomechanical aspects of impingement and dislocation have historically received relatively little scientific attention, although that situation is now rapidly changing. The present article reviews contemporary laboratory and clinical research on the impingement/dislocation phenomena, focusing particularly on how implant design variables, surgical implantation factors and patient activity each act individually and in concert to pose impingement and dislocation challenges. In recent years, several powerful new research methodologies have emerged that have greatly expanded the scope for clinical translation of systematic laboratory study. Transferring the findings from such research into yet better implant designs, and even better surgical procedures, offers encouragement that the clinical impact of this troublesome complication can be further reduced.
全髋关节撞击的发生，无论是否伴有明显脱位，都会带来严重的不良临床后果，尤其是随着耐受性较差的先进轴承植入物设计越来越广泛地使用。撞击和脱位的生物力学方面在历史上受到的科学关注相对较少，不过这种情况现在正在迅速改变。本文回顾了关于撞击/脱位现象的当代实验室和临床研究，特别关注植入物设计变量、手术植入因素和患者活动如何各自单独以及协同作用，对撞击和脱位构成挑战。近年来，出现了几种强大的新研究方法，极大地扩展了系统实验室研究临床转化的范围。将此类研究结果转化为更好的植入物设计以及更好的手术程序，让人看到有望进一步降低这种棘手并发症的临床影响。
