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.

Intramedullary nailing of concurrent ipsilateral fractures of the tibia and femur: primary synchronous nailing versus staged osteosynthesis with temporizing external fixation.

INTRODUCTION: The optimal timing to definitive osteosynthesis in the polytraumatized patient remains an unanswered question. Early total care, damage control orthopaedics, and early appropriate care have been described to manage the fractures in these patients, but there is a paucity of literature specific to ipsilateral tibial and femoral fractures. We sought the perioperative outcomes of primary simultaneous intramedullary nailing (IMN) versus temporizing external fixation (EF) of both fractures. METHODS: A chart review of all patients who sustained fractures of the ipsilateral femur and tibia that were definitively treated with (IMN) from January 2010 to December 2020 was performed. Patients who underwent initial EF and those that were primarily treated with IMNs were examined. RESULTS: IMNs and EF were the initial treatment in 23 and 16 patients, respectively. The mean (range) injury severity score (ISS) was 23.3 (33) in the EF group vs. 18.5 (34) in the IMN group, (p = 0.0686). The EF group had a higher total transfused units of packed red blood cells 7.4 vs. 2.8, the mean initial operative time was 236 vs. 282.6 (min), (p = 0.7399), a longer mean total operative time 601.78 vs. 236 (min), and longer mean length of stay 15.6 vs. 11 (days), (p < 0.5). Rates of complications were not significantly different between groups. CONCLUSION: Primary IMN is as safe as provisional EF in the adequately resuscitated patient with ipsilateral femoral and tibial fractures. This implies the fixation of both fractures into a single surgery without increasing perioperative complications, and decreasing total hospital stay in patients with sufficient preoperative resuscitation.
