Recent data indicate that the contemporary prevalence of dislocation after primary total hip arthroplasty is up to 5- to 10-fold greater in those patients with spinal deformities that lead to stiffness and/or significant pelvic tilt. Moreover, the interplay between the hip and spine is complex, dynamic, and changes over the lifetime of a patient. Finally, the interplay is not fully understood. As such, consideration should be given to the use of dual-mobility constructs in this cohort of patients given the increased effective head size, combined with the dual articulation before hard impingement.
近期数据表明，在因脊柱畸形导致僵硬和/或显著骨盆倾斜的患者中，初次全髋关节置换术后的脱位当代患病率高达 5 至 10 倍。此外，髋关节和脊柱之间的相互作用是复杂的、动态的，并在患者的一生中不断变化。最后，这种相互作用还不完全清楚。因此，鉴于此类患者的有效头尺寸增加，再加上在发生硬性撞击之前有双重关节活动，应考虑在这部分患者中使用双动结构。
