Revision of a failed acetabular component in the presence of an intact femoral prosthesis comprises approximately 20% of revision total hip replacements performed by the senior author. During this procedure, the femoral trunnion is at risk of damage because of scratching from retractors, reamers, or other instruments. Scratching can result in mechanically assisted crevice corrosion or adverse local-tissue reaction or trunnionosis leading to implant failure. We have used a variety of techniques for protection of the femoral taper over the last 30 years. We describe our current method of taper protection, using a cut segment of #5 silicon laryngeal airway, which is a simple and effective method.
在股骨假体完好的情况下翻修失败的髋臼部件，约占资深作者所进行的全髋关节翻修手术的20%。在此手术过程中，由于牵开器、铰刀或其他器械的刮擦，股骨柄有受损风险。刮擦会导致机械辅助缝隙腐蚀、不良局部组织反应或柄部病变，从而导致植入物失效。在过去30年里，我们使用了多种技术来保护股骨锥度。我们描述了目前使用#5号硅胶喉罩气道的切割段进行锥度保护的方法，这是一种简单有效的方法。
