Modularity in total hip arthroplasty design is an evolving concept that continues to receive citation in the clinical literature. The advantages of these systems include off-the-shelf flexibility for customizing proximal and distal canal filling, as well as accommodation of difficult situations of femoral deformity and bone loss. Clinical concerns in the application of modular femoral stem hip designs include the maintenance of anatomical stability within the femoral canal component dissociation, structural compromise at metal-metal interconnections due to cyclic microdisplacements (fretting), and the increased potential for metallic-wear debris generation. This article reviews the rationale and performance of typical modular systems.
全髋关节置换术设计中的模块化是一个不断发展的概念，在临床文献中仍不断被引用。这些系统的优点包括在定制近端和远端髓腔填充方面具有现货供应的灵活性，以及能够适应股骨畸形和骨丢失等复杂情况。模块化股骨柄髋关节设计应用中的临床问题包括股骨髓腔内组件分离时解剖稳定性的维持、由于周期性微位移（微动）导致金属-金属连接处的结构受损，以及金属磨损碎屑产生的可能性增加。本文回顾了典型模块化系统的原理和性能。
