                          THA导向导板


                          THA导向导板可引导髋关节手术中髋臼杯的朝向和位置。在专用软件中,通过CT影像准确分割髋关节,结合断层影像和三维模型选择合适的髋臼杯,根据医生要求规划髋臼杯的前倾角和外展角,设计患者匹配的THA导向导板。术中通过导板置入导向针,平行导向针磨锉髋臼,以实现更好的髋臼朝向。




                          全髋关节整形术 (THA)中,良好的髋臼朝向是手术成功的最重要因素之一。然而在传统的徒手全髋关节置换手术中,术中前倾角、外展角的判定存在盲区,导致术后臼杯朝向不佳。THA导向导板可术中引导髋臼杯的朝向和位置。
