The aim of this report is to evaluate the segmental rib index (RI) from the T1 to T12 spinal levels in mild and moderate idiopathic scoliosis (IS) curves of thoracic, thoracolumbar and lumbar type by gender. The relationship of segmental RI to the frontal plane radiological deformity presented as the Cobb angle and to the posterior truncal surface deformity presented as the scoliometric readings of Angle of Trunk Rotation (ATR) in these patients is also assessed. Any statistically significant relationship between these parameters would be very important for biomechanical relations in rib cage (RC) deformity presented as rib hump deformity (RHD) and deformity in the spine, and would thus provide valuable information about scoliogeny. The segmental rib index (RI) is presented in 83 boys and girls with mild and moderate IS. The measurements include the scoliometric readings for truncal asymmetry (TA), the Cobb angle assessment and the segmental RI from T1-T12. The statistical package SPSS 23 was used for statistical analysis. The TA was documented and the Cobb angle is presented by gender and curve type. The segmental RI of thoracic, thoracolumbar and lumbar curves are presented for the first time. The correlations of the segmental RI to surface deformity presented as rib hump deformity (RHD) in all IS patients, and particularly in thoracic curves, to Cobb angle by gender and age and the comparison of the segmental RI index of asymmetric but not scoliotic children to the scoliotic peers by curve (in thoracic, thoracolumbar, lumbar curves) in boys and girls are presented. The findings emphasize the significant protagonistic role of thoracic asymmetry in relation to the spinal deformity, mainly in girls for the thoracic and in boys for the thoracolumbar curves. The cut-off point of age of the examined scoliotics was 14 years, which is when the RI shows a stronger correlation with spinal deformity, namely when thoracic deformity is decisively effective in the development of thoracic spinal deformity, in terms of Cobb angle. In summary, the results of this study may provide scoliogenic implications for IS, as far as the role of the thorax is concerned.

Patients with rib fractures are a heterogenous group of patients who are treated by general practitioners as well as by specialized trauma surgeons. We present three patients with rib fractures with different degrees of thoracic trauma and therefore treatments differ significantly. The cornerstone in the treatment of rib fractures remains attaining adequate analgesia and breathing exercises. The last decade, there has been an increase in the utilization of rib fixation, however, precise indications remain unknown. It has proven effective in patients with flail chest on mechanical ventilation in whom it decrease intensive care and hospital length and reduces mortality. In case of prolonged (> 3 months) pain, dyspnea or a clicking sensation one could think of a nonunion of the rib fracture. Rib fixation can relieve these complaints in about 60% of the patients, however due to a high implant irritation rate and secondary operation to remove the osteosynthesis is common.

Review
Geriatric trauma has become an increasingly recognized management concern for trauma centers, and hospitals alike, on a national scale. The population of the United States is aging, as life expectancy rates have demonstrated a steady climb to an average of 78.8 years of expected life. With pervasive efforts of medical screening, prevention and chronic medical condition management, more elderly people will lead more active lifestyles and will be more predisposed to injury. As best practice guidelines specific for the geriatric trauma population have yet to be developed, many researchers have identified management strategies that have offset complications and mortality rates inherent to this patient population after injury. The impact of rib fractures in the 65-year and older patient population has been well documented, as have the mortality and pneumonia rates yet, historically, little attention has been directed to curtailing these adverse outcomes with more advanced treatment options. With the advent of rib plating for rib fracture fixation and chest wall stabilization, the practice paradigm for rib fracture management is shifting, as a viable operative intervention now exists. In this review, we focus on the characteristics of the geriatric trauma patient, areas of management where improvement opportunities have been identified, chest wall injury in the elderly patient, rib plating as a treatment option and offer our data to facilitate a better understanding of rib plating's impact in the geriatric trauma patient.

Review
PURPOSE
To identify the clinical and radiologic predictive factors of rib fractures in stable adult outpatients presenting with chest pain and to determine the utility of dedicated rib radiographs in this population of patients.
METHOD AND MATERIALS
Following Institutional Review Board approval, we performed a retrospective review of 339 consecutive cases in which a frontal chest radiograph and dedicated rib series had been obtained for chest pain in the outpatient setting. The frontal chest radiograph and dedicated rib series were sequentially reviewed in consensus by two fellowship-trained musculoskeletal radiologists blinded to the initial report. The consensus interpretation of the dedicated rib series was used as the gold standard. Multiple variable logistic regression analysis assessed clinical and radiological factors associated with rib fractures. Fisher exact test was used to assess differences in medical treatment between the 2 groups.
RESULTS
Of the 339 patients, 53 (15.6%) had at least 1 rib fracture. Only 20 of the 53 (37.7%) patients' fractures could be identified on the frontal chest radiograph. The frontal chest radiograph had a sensitivity of 38% and specificity of 100% when using the rib series as the reference standard. No pneumothorax, new mediastinal widening or pulmonary contusion was identified. Multiple variable logistic regression analysis of clinical factors associated with the presence of rib fractures revealed a significant association of trauma history (odds ratio 5.7 [p < 0.05]) and age ≥40 (odds radio 3.1 [p < 0.05]). Multiple variable logistic regression analysis of radiographic factors associated with rib fractures in this population demonstrated a significant association of pleural effusion with rib fractures (odds ratio 18.9 [p < 0.05]). Patients with rib fractures received narcotic analgesia in 47.2% of the cases, significantly more than those without rib fractures (21.3%, p < 0.05). None of the patients required hospitalization.
CONCLUSION
In the stable outpatient setting, rib fractures have a higher association with a history of minor trauma and age ≥40 in the adult population. Radiographic findings associated with rib fractures include pleural effusion. The frontal chest radiograph alone has low sensitivity in detecting rib fractures. The dedicated rib series detected a greater number of rib fractures. Although no patients required hospitalization, those with rib fractures were more likely to receive narcotic analgesia.

BACKGROUND
Recent studies have reported significant morbidity and mortality in patients with multiple rib fractures, even without flail chest. The aim of this study was to compare the clinical outcome and incidence of associated chest injuries between patients with and without flail chest, with three or more rib fractures.
METHODS
This study included patients with blunt trauma with at least three rib fractures, hospitalised during 2010-2019 in the Hillel Yaffe Medical Center in central Israel (level II trauma centre). Patients with and without radiologically defined flail chest were compared with regard to demographics, Injury Severity Score (ISS), GCS, systolic blood pressure (SBP) on admission, radiological evidence of flail chest, associated chest injuries, length of stay in intensive care unit, length of hospitalisation and mortality.
RESULTS
The study included 407 patients, of which 79 (19.4%) had flail chest. Overall, pneumothorax and haemothorax were more common among patients with flail chest (p<0.05). When comparing patients with three to five rib fractures, there was no difference in length of intensive care and length of hospitalisation or mortality; however, there was a higher incidence of pneumothorax (24.6% vs 50.0%, p<0.05). When comparing patients with six or more rib fractures, no difference was found between patients with and without flail chest.
CONCLUSION
In patients with three to five rib fractures, pneumothorax is more common among patients with flail chest. Clinical significance of flail chest in patients with more than six rib fractures is questionable and flail chest may not be a reliable marker for severity of chest injury in patients with more than six fractures.

Human body models (HBMs) play a key role in improving modern vehicle safety systems to protect broad populations. However, their geometry is commonly derived from single individuals chosen to meet global anthropometric targets, thus their internal anatomy may not fully represent the HBM's target demographic. Past studies show sixth rib cross-sectional geometry differences between HBM ribs and population-derived ribs, and corrections to HBM ribs based on these data have improved HBM's abilities to predict rib fracture locations. We measure and report average and standard deviations (SDs) in rib cross-sectional geometric properties derived from live subject CT scans of 240 adults aged 18-90. Male and female results are given as functions of rib number and rib lengthwise position for ribs 2 through 11. Population means/SDs are reported for measures of rib total area, rib cortical bone area, and rib endosteal area, as well as inertial moment properties of these rib sections. These population corridors are compared between males and females, and against the baseline rib geometries defined in six current HBMs. Total cross-sectional area results found average males ribs to be larger than those of females by between approximately 1-2 SDs depending on rib number and position, and larger in cortical bone cross-sectional area by between 0-1 SDs. Inertial moment ratios showed female ribs being between approximately 0-1 SDs more elongated than male ribs, dependent again on rib number and position. Rib cross-sectional areas from 5 of the 6 HBMs were found to be overly large along substantial portions of most ribs when compared to average population corridors. Similarly, rib aspect ratios in HBMs deviated from average population data by up to 3 SDs in regions towards sternal rib ends. Overall, while most HBMs capture overall trends such as reductions in cross-section along shaft lengths, many also exhibit local variation that deviates from population trends. This study's results provide the first reference values for assessing the cross-sectional geometry of human ribs across a wide range of rib levels. Results also further provide clear guidelines to improve rib geometry definitions present in current HBMs in order to better represent their target demographic.

Clinical evidence has shown that rib-suppressed chest X-rays (CXRs) can improve the reliability of pulmonary disease diagnosis. However, previous approaches on generating rib-suppressed CXR face challenges in preserving details and eliminating rib residues. We hereby propose a GAN-based disentanglement learning framework called Rib Suppression GAN, or RSGAN, to perform rib suppression by utilizing the anatomical knowledge embedded in unpaired computed tomography (CT) images. In this approach, we employ a residual map to characterize the intensity difference between CXR and the corresponding rib-suppressed result. To predict the residual map in CXR domain, we disentangle the image into structure- and contrast-specific features and transfer the rib structural priors from digitally reconstructed radiographs (DRRs) computed by CT. Furthermore, we employ additional adaptive loss to suppress rib residue and preserve more details. We conduct extensive experiments based on 1673 CT volumes, and four benchmarking CXR datasets, totaling over 120K images, to demonstrate that (i) our proposed RSGAN achieves superior image quality compared to the state-of-the-art rib suppression methods; (ii) combining CXR with our rib-suppressed result leads to better performance in lung disease classification and tuberculosis area detection.

Review
Rib fractures are a common and highly morbid finding in patients with blunt chest trauma. Over the past decade, a renewed interest in (and instrumentation for) rib fixation in this cohort has occurred. Stabilization of the chest wall in this setting, particularly when a flail segment is present, is associated with significant reductions in the rates of respiratory failure, pneumonia, ICU stay, and mortality. Thoracic surgeons should remain actively involved in this evolving area of our specialty to further optimize patient outcomes.

Randomized Controlled Trial
BACKGROUND
The aim of this study was to assess pain and quality of life (QoL) outcomes in patients with multiple painful displaced fractured ribs with and without operative fixation. Rib fractures are common and can lead to significant pain and disability. There is minimal level 1 evidence for rib fixation in non-ventilator-dependent patients with chest wall injuries. We hypothesized that surgical stabilization of rib fractures would reduce pain and improve QoL during 6 months.
METHODS
A prospective multicenter randomized controlled trial comparing rib fixation to nonoperative management of nonventilated patients with at least three consecutive rib fractures was conducted. Inclusion criteria were rib fracture displacement and/or ongoing pain. Pain (McGill Pain Questionnaire) and QoL (Short Form 12) at 3 and 6 months postinjury were assessed. Surgeons enrolled patients in whom they felt there was clinical equipoise. Patients who were deemed to need surgical fixation or who were deemed to be too well to be randomized to rib fixation were not enrolled.
RESULTS
A total of 124 patients were enrolled at four sites between 2017 and 2020. Sixty-one patients were randomized to operative management and 63 to nonoperative management. No differences were seen in the primary endpoint of Pain Rating Index at 3 months or in the QoL measures. Return-to-work rates improved between 3 and 6 months, favoring the operative group.
CONCLUSION
In this study, no improvements in pain or QoL at 3 and 6 months in patients undergoing rib fixation for nonflail, non-ventilator-dependent rib fractures have been demonstrated.
