Abstract

We describe a technique for the diagnosis of loosening of the femoral component of the Oxford Unicompartmental Knee Replacement using accurately aligned lateral radiographs in extension and flexion. If gaps are present between the component and cement on one radiograph and not on the other, the component is loose.

摘要

我们描述了一种利用伸直位和屈曲位精确对齐的外侧X线片诊断牛津单髁膝关节置换术股骨组件松动的技术。如果在一张X线片上组件与骨水泥之间存在间隙而另一张上不存在，则组件松动。
