UnlabelledThe presence of major chest wall injury is an indication for transfer to a Level I trauma center. We hypothesized that the presence of three or more rib fractures on initial chest X-ray would identify a small subgroup of patients with a high probability of requiring trauma center care. All trauma discharges in Maryland between 1984 and 1986 (N = 105,683) were reviewed. Patients were divided by the presence of rib fractures (no rib fractures, 1-2 fractures, 3+ fractures) and age in years (0-13, 14-64, 65+).ResultsThe presence of three or more rib fractures in the pediatric age group was rare and precluded further evaluation. When comparing patients with 1-2 rib fractures versus 3 or more rib fractures, significant differences were found in mortality, mean Injury Severity Score, mean hospital stay and mean number of ICU days (p less than 0.001). The significant differences occurred in all age groups 14 years old and older. The presence of three or more rib fractures increased the relative risk of splenic injury (6.2) and liver injury (3.6) but did not predict the presence of aortic injury.ConclusionThe presence of 3 or more rib fractures identifies a small subgroup of patients (2.4%) likely to require tertiary care. This triage tool is useful in all patients over the age of 14 years.
