Joint cartilage functions as a barrier against the extension of bone tumors. However, transarticular invasion by iliopelvic sarcomas across the sacroiliac (SI) joints into the sacrum sometimes occurs. We made a radiological analysis (CT and/or MRI) of 47 bone sarcomas which originated in the ilium and extended nearly to the SI joint 8 of 17 chondrosarcomas and 3 of 30 other sarcomas (2 of 23 Ewing's sarcomas and 1 of 7 osteosarcomas) invaded the sacrum through the SI joint.
关节软骨起到抵御骨肿瘤扩散的屏障作用。然而，髂骨盆肉瘤有时会经骶髂（SI）关节跨关节侵犯至骶骨。我们对47例起源于髂骨且几乎延伸至SI关节的骨肉瘤进行了影像学分析（CT和/或MRI），其中17例软骨肉瘤中的8例以及30例其他肉瘤中的3例（23例尤因肉瘤中的2例和7例骨肉瘤中的1例）经SI关节侵犯至骶骨。
