    BackgroundSurgical fixation of humeral shaft fractures is widely considered a relative indication for polytraumatized patients to improve mobility and expedite care. This study aimed to determine whether operative treatment of humeral shaft fractures improves short term outcomes in polytrauma (PT] patients.MethodsUsing the National Trauma Data Bank, PT patients with humeral shaft fractures were identified from 2010-2015. Three PT groups were analyzed: Group 1 - PT with nonoperative humeral shaft fracture, Group 2 - PT with humeral fixation on Day 1, and Group 3 - PT with humeral fixation on Day 2+. Cox proportional hazards regression models were used to compare discharge timing and days on ventilator and in ICU between the three groups.ResultsThere were 395 patients in Group 1, 1,346 in Group 2, and 1,318 in Group 3. There were no differences between the three groups when comparing Glasgow Coma Scale (p=0.3]; however, Injury Severity Score and Abbreviated Injury Scale were statistically different (p<0.001]. No differences were found in ICU or ventilator days between the three groups (p=0.2, p=0.5]. For Length of Stay, no difference was observed in Group 1 vs. Group 2 and Group 2 vs. Group 3. However, non-surgical patients were discharged 20% faster than those with Day 1 surgery (p=0.005]. Open fractures were treated one day earlier than closed fractures but discharged one day later (p<0.001].ConclusionsThis NTDB study demonstrates no differences in length of stay, days in the ICU or on the ventilator in patients with humeral shaft fractures treated non-operatively versus operative fixation. Overall, 44%-58% in all 3 groups had an ISS ≥ 14. Based on these results, we assert that fixation of the humeral shaft provides no short-term benefits in the multiply injured patient.Copyright © 2022. Published by Elsevier Ltd.
