Rib Fracture Map in High-Energy Injuries

Abstract

Objectives: To use a novel rib unfurling technology to investigate the locations of multiple rib fractures occurring from high-energy trauma to discern if there are reproducible rib fracture patterns.Methods: Patients between the ages of 18 and 48 years presenting to a Level 1 academic trauma center with $2 rib fractures after a high-energy mechanism of injury between 2017 and 2019 were identified. Curved planar reformatting of CT scans was used to create two-dimensional unfurled rib images by flattening out the view of the ribs from a CT scan. Rib fractures were placed on a template map using a standardized measurement method, and subsequent frequency and heat maps were created.Results: Among 100 consecutive patients, 534 fractures on 454 ribs were identified. The most common high-energy mechanism of injury was motor vehicle accidents (41%). Flail chest occurred in 8% of patients. The mean number of ribs fractured per patient was 4.54 6 3.14 and included a mean of 5.34 6 4.38 total fractures. Among all fractures, 50.9% were located on ribs 4 through 7. The most common fracture location was located in the lateral or anterolateral zone of the rib cage.Conclusions: Patients with multiple rib fractures from high-energy trauma have rib fractures with locations of common occurrence. An understanding of location and frequency of rib fractures can help inform surgical approaches, prognosis, indications, classifications, and implant design in the management of a complex population of patients with chest wall injury after trauma.

Efficacy and safety of ultrasound‐guided erector spinae plane block compared to sham procedure in adult patients with rib fractures presenting to the emergency department: A randomized controlled trial

“…The primary precipitating event for rib fractures in our study was road traffic accidents, with the lateral and anterolateral segments of the ribs bearing the brunt of the injuries. This aligns with other research findings that identify road traffic accidents as the main culprit behind traumatic rib fractures, with high‐velocity trauma most frequently fracturing the lateral and anterolateral ribs 18 . Similar results were observed in our study, where around two‐thirds of the ribs were fractured on their lateral aspect.…”

Following a rib fracture, effective pain management is crucial.…”
