Leg length discrepancy is not an uncommon result of total hip arthroplasty and a major cause of patient dissatisfaction. Spinopelvic obliquity is a less-recognized cause of limb length differences in patients undergoing total hip arthroplasty. The robotic arm has recently been introduced to enhance implant positioning during surgery and to achieve more predictable leg length and offset goals. In this article, we illustrate the case of a patient who presented with a leg length discrepancy associated with significant spinopelvic obliquity. We show the use of the robotic arm total hip application to improve her pelvic obliquity and limb length discrepancy. This approach helped with the patient's symptoms and gait as well as her radiographic pelvic alignment.
肢体长度差异是全髋关节置换术后并不罕见的结果，也是患者不满的主要原因。脊柱骨盆倾斜是全髋关节置换术患者肢体长度差异中一个较少被认识到的原因。最近引入了机器人手臂以在手术期间增强植入物定位，并实现更可预测的肢体长度和偏移目标。在本文中，我们阐述了一名存在与显著脊柱骨盆倾斜相关的肢体长度差异的患者的病例。我们展示了使用机器人手臂全髋关节应用来改善她的骨盆倾斜和肢体长度差异。这种方法有助于缓解患者的症状和改善步态，以及改善其骨盆在影像学上的对线情况。
