Hundreds of thousands of revision surgeries for hip, knee, and shoulder joint arthroplasties are now performed worldwide annually. Partial removal of hardware during some types of revision surgeries may create significant amounts of third body metal, polymer, or bone cement debris. Retained debris may lead to a variety of negative health effects including damage to the joint replacement. We describe a novel technique for the better containment and easier removal of third body debris during partial hardware removal. We demonstrate hardware removal on a hip joint model in the presence and absence of water-soluble gel to depict the reduction in metal debris volume and area of spread.
目前，全球每年要进行数十万例髋关节、膝关节和肩关节置换翻修手术。在某些类型的翻修手术中，部分取出植入物可能会产生大量的第三体金属、聚合物或骨水泥碎片。残留的碎片可能会导致各种负面健康影响，包括对关节置换物的损害。我们描述了一种新技术，可在部分取出植入物时更好地收集并更轻松地清除第三体碎片。我们展示了在有和没有水溶性凝胶的情况下，在髋关节模型上取出植入物的过程，以描述金属碎片体积的减少和扩散面积。
