Femur fractures in chest-injured patients: is reaming contraindicated?
OBJECTIVE
To determine if reamed femoral intramedullary nailing increases the pulmonary complications seen in chest-injured patients.


METHODS
Retrospective review of prospectively collected trauma database data from January 1991 to October 1994.


METHODS
Methodist Hospital, Indianapolis, Indiana, Level I Trauma Center.


METHODS
Group I: Chest-injured patients [chest Abbreviated Injury Score (AIS) > or = 2] without femur or tibia fractures. Group II: Chest-injured patients (chest AIS > or = 2) with femoral reamed intramedullary fixation. Group III: Chest-injured patients (chest AIS > or = 2) with femoral shaft fixation using nonreamed fixation (rush rods, plating, or external fixation). Group IV: Non-chest-injured patients (chest AIS < 2) with femoral reamed intramedullary fixation. MAIN OUTCOME MEASUREMENT/HYPOTHESIS: Reamed femoral intramedullary nailing does not alter pulmonary outcomes, even in chest-injured patients.


RESULTS
Groups I and II had a very similar incidence of adult respiratory distress syndrome (ARDS), pneumonia, and number of ventilator days. Group III had a significantly higher incidence of ARDS and number of ventilator days than did Group I or II. Group III did not have a chest AIS score significantly different than Groups I and II. Group II had significantly higher ARDS and more ventilator days than did Group IV when only analyzing raw data. When injury severity was adjusted, there were no significant differences in pulmonary outcomes.


CONCLUSIONS
Reamed intramedullary femoral fixation did not increase pulmonary morbidity in chest-injured patients.
