Abstract:

 BACKGROUND: Large volume of bone can be harvested by the reamer-irrigation-aspirator (RIA), which can be used for autologous bone graft, because there are many stromal stem cells and a variety of osteogenesis factors in the harvested bone.

OBJECTIVE: To introduce the application progress of the RIA.
METHODS: PubMed database was retrieved by the first author for RIA-related articles published from January 2000 to May 2017 using the keyword of “reamer-irrigator-aspirator”. A total of 87 articles were searched initially and finally 38 articles met the inclusion criteria.
RESULTS AND CONCLUSION: Compared with harvesting bone tissues from the iliac bone, the RIA can harvest more autologous bone tissues with more bone marrow stromal stem cells. Moreover, the osteogenic effect of the harvested autologous bone is better and there are fewer complications. Therefore, the RIA has been widely used as a method of harvesting non-structural autologous bone tissues. Removal of intramedullary lesions by the RIA is used in the treatment of long bone infection, osteomyelitis and bone tumors, as well as in the removal of intramedullary cement. RIA was originally used as a special reaming during intramedullary nailing for femoral shaft fractures, which could reduce high pressure and high temperature so as to decrease the risks of fat embolism and osteonecrosis. To conclude, the RIA can achieve satisfactory outcomes and result in few complications, but the clinical use is still limited by high cost, frequent fluoroscopy, bleeding and limited indications, as well as risks for iatrogenic fractures and perforation.
