Component malpositioning during Birmingham hip resurfacing increases the risk for component wear, metallosis, component loosening, and the likelihood of dislocation and revision surgery. Computer-assisted navigation can increase the accuracy to which components are placed, and the utilization of this technology in Birmingham hip resurfacing is increasing. The present report summarizes the accuracy of acetabular component positioning in a Birmingham hip resurfacing case utilizing navigation. Intraoperative C-arm fluoroscopy following the use of the navigation tool confirmed excellent seating, positioning, and stability of the acetabular component. In addition, post-operative antero-posterior radiographs confirmed device accuracy and revealed a stable joint with no evidence of acetabular loosening or femoral fracture. Computer-assisted navigation may therefore be an effective tool to improve the accuracy of component positioning during Birmingham hip resurfacing.
在伯明翰髋关节表面置换术中，组件位置不当会增加组件磨损、金属沉着病、组件松动的风险，以及脱位和翻修手术的可能性。计算机辅助导航可以提高组件放置的准确性，并且这项技术在伯明翰髋关节表面置换术中的应用正在增加。本报告总结了在一例使用导航的伯明翰髋关节表面置换病例中髋臼组件定位的准确性。使用导航工具后术中C形臂透视证实髋臼组件就位良好、位置准确且稳定。此外，术后前后位X线片证实了装置的准确性，并显示关节稳定，没有髋臼松动或股骨骨折的迹象。因此，计算机辅助导航可能是提高伯明翰髋关节表面置换术中组件定位准确性的有效工具。
