To what extent the cardiopulmonary and inflammatory response is affected by initial femoral intramedullary nailing in the already traumatized and inflammatory activated patient was analyzed in the present study with the attention to survey the additional burden of this operative treatment. The patients are monitored with a pulmonary catheter, and blood samples for coagulation, fibrinolysis, complement and cytokine response are withdrawn pre-, per- and postoperatively. The study is partly randomized 1)where delayed intramedullary nailing is compared with primary nailing of the femur, and 2) a new reaming technique (RIA) is compared with a standard reaming technique (TR).

Estimated Enrollment: 36
Study Start Date: May 2003
Estimated Study Completion Date: May 2012
Estimated Primary Completion Date: October 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 1) IMN and EF/IMN

Two parts of the study are randomized;

1)initial intramedullary reaming and primary external fixation with secondary intramedullary nailing

Procedure: the effect of delayed intramedullary reaming
in one group intramedullary reaming and nailing is performed immediately, femoral fractures in the second group are external fixated and than secondary nailed.
Active Comparator: 2) TR and RIA
Two parts of the study are randomized; 2)traditional reaming (TR)is compared to a new reaming device, RIA, which is a reamer connected to suction and flushing for prevention of increased intramedullary pressure
Procedure: the reaming of the femoral canal is performed with two different reaming devices
the reaming of the femoral canal is performed with two different reaming devices; a traditional reamer (TR)and the reamer-irrigator-aspirator (RIA)
