Systematic Review Of Reamed Versus Nonreamed Intramedullary Nailing For Femoral Fractures

Objectives: To determine the effect of reamed versus nonreamed intramedullary nailing for femoral fractures on the time of union and the rates of failure, pulmonary implications, malunion and infection. Methods: MEDLINE, EMBASE, Cochrane Library and CBMdisc were searched for RCTs and CCT. Data was extracted by two reviewers using the designed extraction form. RevMan were used for data management and analysis. Results Five RCTs and two CCTs were included. The combined results showed that reamed intramedullary nailing for femoral fractures reduce the rates of nonunion and implant failure. Conclusion: To compare with nonreamed intramedullary nailing for femoral fractures, reamed intramedullary nailing can reduce the rates of nonunion and implant failure. However, the relation between whether is reaming or not and pulmonary complications, the time to union, infection, malunion, operative time, blood loss, and influences of whether is open fracture, combined multiple injury or not, fracture site, etc. on the index above need furthrer study.
