ABSTRACT
Objective To investigate complications and mortality of primary reamed intramedullary nailing for femoral shaft fractures in patients a ssociated with thoracic injuries. Methods A retrospective a nalysis of trauma data was performed and the case selection based on the followi ng criteria: (1) patient age of 17-65 years, (2) patients with multiple injury ( ISS≥16) as well as complicated thoracic trauma (AIS≥2), (3) hospitalization stay ≥48 hours, (4)no serious pre-existing medical diseases in history, (5) as sociated femoral shaft fractures treated with reamed intramedullary nailing, ext ernal fixation, plate, cast, traction and unreamed intramedullary nailing. The s elected patients were divided into two groups according to the interval from inj ury to operation, ie, those within 24 hours as Group A and beyond 24 hours as Gr oup B. Results During the study period, 96 patients met the criteria for the investigation. There were 57 patients in the Group A and 39 pa tients in the Group B. In two groups, there was significant difference in incide nce of open femoral shaft fractures (53% in the Group A and 31% in the Group B, ? 2=4.496, P
