文摘

Spinopelvic reconstruction after sacrectomy for a sacropelvic tumor can result in various complications and requires a highly complicated surgical technique. We report 2 cases of pelvic reconstruction surgery using diverse U-shaped rods (USRs) after partial sacrectomy.

Case Description

A partial sacrectomy was performed for 2 different cases: one case was a metastatic sacral tumor and the other was a chordoma. In the first case, reconstruction was completed with an inner straight rod and an outer USR. The other patient underwent reconstruction using an inner USR and an outer straight rod. In both cases, there was no instrument failure, and the lumbosacral junction was reconstructed in balance. One of the patients died of metastatic lung cancer, and the other patient is alive and has experienced no other complications.

Conclusions

A pelvic reconstruction technique using diverse USRs showed good spinopelvic stability without complications. This technique may be a surgical option for reconstructive surgery after partial sacrectomy.
