Mechanical loading of the lower extremities due to muscle and joint contact forces plays an important role in orthopaedic and trauma surgery. Detailed, patient specific information on the in vivo forces and their distribution is, however, currently not readily available to the surgeon in clinical routine. The goal of this study was to elucidate the relationship between the position of the cup and the musculoskeletal loading conditions at the hip using validated analyses, and further, to evaluate the predictions of the biomechanical conditions against the results of a clinical study. The results indicate that restoring the anatomical hip centre to its anatomical mediolateral position could help to reduce joint loads and add to the longevity of the reconstruction. The routine use of validated analyses of musculoskeletal loading conditions, such as in the presented example using standardised pre-operative planning and sound intra-operative decision support systems, could contribute to securing a high standard in patient treatment.
由于肌肉和关节接触力导致的下肢机械负荷在骨科和创伤手术中起着重要作用。然而，目前临床常规中外科医生尚无法轻易获得详细的、针对患者个体的体内力及其分布信息。本研究的目的是使用经过验证的分析方法阐明髋臼杯位置与髋关节肌肉骨骼负荷状况之间的关系，此外，根据一项临床研究的结果评估生物力学状况的预测。结果表明，将解剖学髋关节中心恢复到其解剖学中外侧位置有助于减轻关节负荷并延长重建的使用寿命。常规使用经过验证的肌肉骨骼负荷状况分析方法，例如在本示例中使用标准化的术前规划和完善的术中决策支持系统，有助于确保患者治疗达到高标准。
