Early intramedullary nailing of bilateral femur fractures: who might benefit most?

INTRODUCTION

Identifying which patients can receive immediate intramedullary nailing (IMN) after bilateral femoral shaft fracture may improve health-related quality of life outcomes and decrease healthcare costs. This retrospective study evaluated the perioperative factors that guided emergency department transfer of patients to the operating room (OR) where IMN or temporizing external fixation (TEF) was performed, to the intensive care unit (ICU), or to the orthopedic ward. The hypothesis was that patients referred initially to the OR or to the ICU had more serious co-morbidities, complications, or orthopedic polytrauma, increasing the likelihood that they would benefit from "damage control orthopedics" and TEF use.

METHODS

A Level I Trauma Center database (2010-2020) review identified the records of 23 patients that met study inclusion and exclusion criteria. Most sustained their injury in a motor vehicle accident (87%) and were not wearing a seatbelt.

RESULTS

Patients transferred to the operating room had a greater body mass index and shorter times between admission and surgery. Those transferred to the OR or ICU had higher injury severity scores (ISS), higher arterial blood O2 partial pressure (paO2) values on the first post-surgical day, and had more red blood cell unit (RBCU) transfusions during hospitalization. Patients transferred to the ICU more often underwent TEF and had shorter initial surgical procedure duration. Those with pneumothorax, rib fractures, or with other orthopedic comorbidities were more often transferred to the OR or ICU and those with acute complications requiring exploratory laparotomy were transferred to the OR.

CONCLUSIONS

Patients with higher BMI, ISS, greater RBCU transfusion needs, with pneumothorax, rib fractures, or acute complications requiring exploratory laparotomy were more likely to be initially transferred to the OR or ICU. Patients transferred to the orthopedic ward represented a more heterogenous group with greater possibility for benefitting from earlier definitive IMN.
