PURPOSE: Intrathoracic and intra-abdominal injuries in patients with rib fractures are often overlooked, leading to delayed and ineffective treatment. However, the relationship between rib fractures and organ damage has been rarely studied. The purpose of this study was to analyze the risk factors associated with intrathoracic and intra-abdominal injuries in patients with rib fractures. METHODS: This retrospective observational study included 1269 patients diagnosed with rib fractures from September 2020 to April 2023. Patient data were collected, including gender, age, body mass index, systolic blood pressure, heart rate, type of rib fracture, number of fractured ribs, location of the rib fracture, and the presence of thoracic and abdominal organ injuries. Patients without imaging examinations, the patient with rib fractures from iatrogenic causes or mental illnesses or rheumatic immune diseases was excluded. The primary outcomes were intra-thoracic and intra-abdominal injuries. Multivariate logistic regression analysis was conducted to identify the risk factors for these injuries in patients with rib fractures. RESULTS: The rib fracture characteristics in the occurrence group included bilateral fractures, higher number of fractures (≥3), and fractures located anteriorly, posteriorly, and laterally, as well as greater fracture displacement, compared to the non-occurrence group. The results of the multivariate logistic regression analysis indicated that age (p=0.016, odds ratio (OR)=0.95, 95% confidence interval (CI: 0.92-0.98), the number of rib fractures (≥3, p=0.001, OR=1.46, 95% CI: 1.13-1.89), rib type (bilateral rib fractures, p=0.043, OR=2.63, 95% CI: 2.16-3.12), and rib fracture location (lateral rib fractures, p=0.041, OR=2.85, 95% CI: 1.31-4.97; posterior rib fractures, p=0.022, OR=3.25, 95% CI: 1.46-6.92) were independent risk factors for thoracic and abdominal organ injuries in patients with traumatic rib fractures. CONCLUSIONS Patients with rib fractures resulting from blunt trauma, particularly those with lateral or posterior rib fractures, fractures involving more than 3 ribs, and bilateral rib fractures, are at an increased risk for significant intrathoracic and intra-abdominal injuries. These findings warrant attention and the implementation of appropriate preventive measures during treatment.

PURPOSE: Rib fractures are one of the most common causes of morbidity and mortality and are associated with abdominal solid organ injury (ASOI). The purpose of this study was to investigate the correlation of ASOI with the number, location, and involved segments of rib fracture(s) in blunt chest trauma. METHODS: This retrospective cohort study was conducted on patients with blunt chest trauma over the age of 15 years, who were hospitalized with the diagnosis of rib fractures from July 2015 to September 2020. After ethic committee approval, a retrospective chart review was designed and patients with a diagnosis of rib fractures were selected. Patients who had chest and abdominopelvic CT scan were included in the study and additional data including age, gender, injury severity score, trauma mechanism, number and sides of the fractured ribs (left/right/bilateral), rib fracture segments (upper, middle, lower zone) and results of chest and abdominal spiral CT scan were recorded. The correlation between ASOI and the sides, segments and number of rib fracture(s) was assessed by Pearson's correlation coefficient. RESULTS: Altogether 1056 patients with rib fracture(s) were included. The mean age was (42.76 ± 13.35) years and 85.4% were male. The most common mechanism of trauma was car accident (34.6%). Most fractures occurred in the middle rib zone (60.44%) and the most commonly involved ribs were the 6th and 7th ones (15.7% and 16.4%, respectively). Concurrent abdominal injuries were observed in 103 patients (34.91%) and were significantly associated with middle zone rib fractures. CONCLUSION There is a significant relationship between middle zone rib fractures and ASOI. Intra-abdominal injuries are not restricted to fractures of the lower ribs and thus should always be kept in mind during management of blunt trauma patients with rib fractures.

Rib fractures are one of main causes of chest or flank pain when related to an osteoporotic vertebral compression fracture (OVCF). The authors investigated the incidence and risk factors of rib fracture in 284 patients with OVCF using bone scans and evaluated the feasibility as to whether bone scans could be utilized as a useful screening tool. Hot uptake lesions on ribs were found in 122 cases (43.0%). The factors analyzed were age, sex, number and locations of fractured vertebrae, BMD, and compression rates as determined using initial radiography. However, no statistical significances were found. In 16 cases (5.6%), there were concurrent multiple fractures of both the thoracic and lumbar spines not detected by single site MRI. Sixty cases (21.1%) of OVCF with the a compression rate of less than 15% could not be identified definitely by initial plain radiography, but were confirmed by bone scans. It is concluded that a bone scan has outstanding ability for the screening of rib fractures associated with OVCF. Non-adjacent multiple fractures in both thoracic and lumbar spines and fractures not identified definitely by plain radiography were detected on bone scans, which provided a means for determining management strategies and predicting prognosis.
