Kim et al used a grading system to describe rib fractures that occurred following stereotactic body radiation therapy (SBRT) in patients with a peripheral lung tumor. The authors are from University of Ulsan in Seoul.
Patient selection: rib fracture following SBRT for a peripheral lung tumor
Parameters:
(1) rib diameter in centimeters
(2) displacement of fractured end
Changes Seen on Imaging Studies
Grade
no fracture line
0
fracture line on X-ray, nondisplaced
1
rib end displaced > 50% of rib diameter
2
displaced rib AND adjacent soft tissue edema
3
Moderate to severe chest wall pain increased with the grade of the fracture.
