Hip instability continues to be an infrequent, yet frustrating complication of total hip arthroplasty (THA). Restoration of normal hip anatomy and biomechanics at the time ofTHA is critical to reduce the risk of dislocation. This can be difficult in some patients due to distorted hip anatomy and wide variations in "normal" hip anatomy reported in numerous studies. Modular femoral components offer a large array of femoral offset, length, and version options which can be used independently or in combination to recreate normal osseous anatomy and a well-tensioned soft tissue envelope, which should enhance hip stability following THA.
髋关节不稳定仍然是全髋关节置换术（THA）中一种少见但令人沮丧的并发症。在进行全髋关节置换术时恢复正常的髋关节解剖结构和生物力学对于降低脱位风险至关重要。由于髋关节解剖结构扭曲以及众多研究报道的“正常”髋关节解剖结构存在广泛差异，这在一些患者中可能具有挑战性。模块化股骨组件提供了大量的股骨偏心距、长度和旋转角度选择，这些可以单独使用或组合使用，以重建正常的骨解剖结构和张力良好的软组织包膜，这应该能增强全髋关节置换术后的髋关节稳定性。
