Outcomes of closed reduction with interlocking intramedullary nails in treatment of femoral shaft fractures

Objective To evaluate the clinical outcomes of closed reduction with interlocking intramedullary nails in treatment of femoral shaft fractures.Methods Data of 48 cases with femoral shaft fractures treated with interlocking intramedullary nails were retrospectively analyzed,of whom 32 patients underwent close reduction with interlocking intramedullary nails(group A) and 16 patients underwent conventional open reduction(group B).The outcomes were compared between two groups.Results A total of 32 cases in group A and 16 cases in group B were followed up for averaged 6 months.The blood loss during surgery was less in group A than that in group B [(196±54) ml vs.(480±63) ml](P0.05).So did the time of union after operation [(4.5±2.1) months vs.(5.8±2.9) months](P0.05).The excellence rate of the joint function after operation was higher in group A than that in group B(90.0% vs.86.7%)(P0.05).There were no significant differences in operative time and rotational stability after surgery.Conclusion Closed reduction with interlocking intramedullary nail is better than conventional open reduction in treating femoral shaft fractures.
