To determine if intraoperative positioning in the supine or lateral position affects morbidity and mortality in orthopaedic trauma patients with femur fractures.

Retrospective cohort study of 991 patients representing 1030 femoral shaft fractures admitted to our level one trauma center between the years of 1987 to 2006. Primary outcome measures included mortality and admission to ICU. Secondary outcome measures included length of stay in hospital, length of time admitted to the intensive care unit and discharge disposition. Logistic regression analysis was performed to compare to effect of intraoperative position in addition to other known dependent variables on primary and secondary outcome measures.

Intraoperative position in the supine or lateral position had no effect on morbidity or mortality in orthopaedic trauma patients with femur fractures.

There is no difference in immediate mortality or morbidity between patients with femur fractures treated with IM nails in either the lateral or supine position. We conclude that either position is safe for the surgical stabilization of femur fractures and intraoperative position should be determined by surgeon preference.
