Correct component placement is of significant importance to ensure optimal outcomes in total hip arthroplasty (THA). Traditionally, the Lewinnek plane has been referenced as an adequate "safe zone", formed between the anterior superior iliac spines and public tubercles to optimize acetabular orientation. However, recent evidence shows that the positioning of this plane may vary due to the biomechanical relationship between the lumbar spine and hip. Therefore, the plane acquired intraoperatively may not accurately recreate the actual functional plane and acetabular orientation encountered outside of the intraoperative environment. This review summarizes the hip-spine relationship and its implications on THA.
正确放置组件对于确保全髋关节置换术(THA)的最佳效果至关重要。传统上,Lewinnek平面被视为一个合适的“安全区”,它在前上棘和耻骨结节之间形成,以优化髋臼的方向。然而,最近的证据表明,由于腰椎和髋关节之间的生物力学关系,这个平面的位置可能会有所不同。因此,术中获得的平面可能无法准确重现术中环境之外实际的功能平面和髋臼方向。这篇综述总结了髋关节与脊柱的关系及其对全髋关节置换术的影响。
