Hip, spine, and pelvis function as a unified kinetic chain. Any spinal pathology, results in compensatory changes in the other components to accommodate for the reduced spinopelvic motion. The complex relationship between spinopelvic mobility and component positioning in total hip arthroplasty presents a challenge in achieving functional implant positioning. Patients with spinal pathology, especially those with stiff spines and little change in sacral slope, are at high instability risk. In this challenging subgroup, robotic-arm assistance enables the execution of a patient specific plan, avoiding impingement and maximizing range of motion; especially utilizing virtual range of motion to dynamically assess impingement.
髋关节、脊柱和骨盆作为一个统一的运动链发挥作用。任何脊柱病理都会导致其他组成部分发生代偿性变化，以适应减少的脊柱骨盆运动。全髋关节置换术中脊柱骨盆活动度与组件定位之间的复杂关系，给实现功能植入物的定位带来了挑战。患有脊柱疾病的患者，特别是脊柱僵硬且骶骨倾斜度变化不大的患者，存在较高的不稳定性风险。在这个具有挑战性的亚组中，机器人辅助可以执行患者特定的计划，避免撞击并最大限度地扩大运动范围；特别是利用虚拟运动范围来动态评估撞击。
