Research progress in reamer-irrigator-aspirator technique in the treatment of bone defects and intramedullary canal infection / 中华创伤杂志

ABSTRACT

Treatment of large bone defects and nonunion induced by various causes requires bone graft, and autologous iliac bone graft has always been considered as the gold standard for the treatment of bone transplantation. However, there exist problems such as postoperative pain and numbness in the donor area or insufficient bone taking. The application of reamer-irrigator-aspirator（RIA）technique can reduce complications in the donor area and collect a maximum of 90 ml of autologous bone to treat large bone defects. In addition, it can also be used to remove the infected lesion and residual bone cement in the medullary cavity. The authors review the instrument structure, operation process, clinical application and complications of RIA technique, so as to provide a reference in the treatment of bone defects and intramedullary canal infection.
