Hip instability after total hip replacement has been shown to be a critical cause of failure. The use of dual mobility has been classically restricted to patients "at risk", over 70 years of age. The question rises up about extended indications of so-called "modern" second generation dual mobility cups. This prospective multicenter study reports on first results at 2-5 years of the HA anatomical ADM cup upon two comparative groups of patients under 70 years (112 hips) vs. over 70 years of age (325 hips). No dislocation, migration, tilting, wear, or intra-prosthetic dislocation was recorded within each of the two cohorts. Survivorship for cup failures at this 4-year period was ideal at 100% in the younger patients, and 99.7% in the older group of patients.
髋关节置换术后髋关节不稳定已被证实是导致失败的一个关键因素。双动技术的使用传统上仅限于“高危”、70 岁以上的患者。因此，关于所谓的“现代”第二代双动杯的扩展适应证的问题也随之出现。本前瞻性多中心研究报告了 HA 解剖型 ADM 杯在两个比较组中的 2-5 年的初步结果，这两个比较组分别为 70 岁以下（112 髋）和 70 岁以上（325 髋）的患者。在这两个队列中，每个队列均未记录到脱位、迁移、倾斜、磨损或假体内脱位。在 4 年的研究期间，年轻患者的杯失败生存率为 100%，年龄较大的患者为 99.7%。
