Background:
The thoracic cage is an anatomical entity formed by the thoracic spine, ribs, and sternum. As part of this osteoligamentous complex, the sternum contributes substantially to the stability of the thoracic spine. This study investigates the influence of a concomitant sternal fracture (SF) on the treatment and hospital course of pediatric patients with a thoracic vertebral fracture (TVF).
Methods:
The Trauma Quality Improvement Program data sets from 2016 to 2020 were reviewed. Patients aged 0 year to 19 years with TVF with or without SF following blunt trauma were identified using the Abbreviated Injury Scale codes and selected for further data collection. Patients with transverse or spinous process fractures or incomplete data were excluded. Data collected included demographics, mechanisms of injury, clinical variables, procedures, intensive care unit admission and length of stay, total length of stay and in-hospital mortality. Continuous variables were analyzed with Wilcoxon rank sum test, categorical variables with χ 2 test.
Results:
A total of 13,434 patients were identified, of which 10,292 had isolated TVF (TVF), 788 TVF and concomitant SF (TVF + SF), 2,225 isolated SF (excluded), and 126 incomplete data (excluded). Motor vehicle collisions were the most common mechanism of injury in both groups (TVF, 75%; TVF + SF, 88%), followed by falls (TVF: 23%, TVF + SF: 12%). Spinal cord injuries were more common among TVF + SF patients (6.4% vs. 4%). Median injury severity score (17 vs. 12), age (17 vs. 15 years), LOS (5 vs. 3 days), and mortality (5.6% vs. 2.3%) were significantly higher and the need for operative treatment (69% vs. 56%) and ICU admission (53% vs. 36%) significantly more frequent in patients with TVF + SF.
Conclusion:
Concomitant SF occur in 7% of all pediatric patients with TVF and are associated with increased morbidity and mortality. This combination of injuries is likely the result of greater energy transmission and injury potential.
Level Of Evidence:

History:
01:24Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
