Traumatic flail chest

Case contributed by Dr Andrew Dixon

Presentation

Fall from height onto chest.

Patient Data

Age: 45
Gender: Male

This case featured in our 2016 Trauma Radiology Course which is now available to view online.

Trauma Series

Modality: X-ray

Comminuted right clavicular shaft fracture. Multiple right rib fractures laterally. Right 5th rib fracture posteriorly. No definite haemothorax or pneumothorax seen. Mediastinal contour is probably normal for a supine projection.

CT Chest - 3 days after injury

Modality: CT

Right 3rd to 6th rib, right 7th transverse process and right 8th to 9th rib fractures posteriorly about the costotransverse joints. The right 4th to 8th ribs are also fractured laterally. This produces a significant flail segment despite a relatively innocuous looking initial chest x-ray. Comminuted right clavicular shaft fracture. Right basal intercostal catheter insitu with residual small to moderate volume right haemothorax, right lower lobe collapse / consolidation likely due to pulmonary haemorrhage and patchy lung contusion elsewhere. Trace left pleural fluid. 

10 days after injury

Modality: X-ray

10 days later the patient remained in hospital with the flail segment now easily visible due to increased displacement. The right lower lobe remains collapsed. 

Case Discussion

This case demonstrates how seemingly minor rib fractures on an initial trauma chest x-ray can actually be part of a significant flail segment when investigated with CT. Internal fixation of ribs was not initially performed in this patient and unfortunately substantial displacement of the flail segment and persistent lower lobe collapse occurred.
