PURPOSE
The primary aim of this retrospective cohort study was to evaluate the pulmonary function after rib fixation for patients with multiple rib fractures and flail chest. Secondary, a systematic review was performed to give an overview of the current literature and to allow comparison with our results.
METHODS
All adult (≥ 18 years) patients who underwent rib fixation for multiple rib fractures or flail chest between 2010 and 2018 and who received a control pulmonary function test during the postoperative follow-up at our level-1 trauma center were retrospectively reviewed. Secondary, the PubMed, EMBASE and Cochrane databases were searched to identify studies reporting on the pulmonary function after rib fixation. The primary outcome parameters were the forced vital capacity (FVC), forced expiratory volume in 1 s (FEV), FEV/FVC ratio, maximum vital capacity (VC), total lung capacity (TLC), residual volume (RV), and RV/TC ratio.
RESULTS
Of the 103 patients who underwent rib fixation, a total of 61 (59%) patients underwent a pulmonary function test in our hospital and were ultimately included. In the majority of patients all pulmonary function parameters fell within the normal range of the reference values. Obstructive impairment was predominantly seen in patients with pre-existing chronic obstructive pulmonary disease (COPD). Patients with multiple rib fractures had better recovery compared to those with a flail chest. The systematic review included a total of 15 studies and showed comparable results.
CONCLUSION
The present study demonstrates that rib fixation for multiple rib fractures or flail chest results in adequate recovery of the pulmonary function within 3 months after surgery. In addition, based on the current literature, further gradual improvement to maximum pulmonary values appears to occur during the first 12 months after rib fixation.

Review
INTRODUCTION
Cadaveric fresh frozen cartilage provides an enticing alternative to traditional autologous cartilage grafts. This review provides a systematic analysis of existing literature on the use of fresh frozen rib for in rhinoplasties and focuses on clinical and aesthetic outcomes.
METHODS
The methodology was designed and registered in the PROSPERO database (CRD42023447166). The Preferred Reporting Items for Systematic Reviews and Meta-Analysis guideline was used to perform this systematic review.
RESULTS
Four articles were included, with a total of 554 patients. A total of 477 patients were female (86%). Mean age ranged between 35.8 and 40.6. Mean follow-up ranged from 12.2 to 20.3 months. Only one article had a suitable control (with autologous rib graft). Pooled complications rates were low. Infection occurred in 12 patients (2%), warping in 8 patients (1.4%) and resorption in 3 patients (0.5%).
CONCLUSION
Fresh frozen cartilage may be a safe and reliable alternative to autologous rib grafts. Complication rates were comparable to previous systematic reviews of autologous graft and irradiated allograft. Overall, patients reported high satisfaction rates with low rates of revision procedures. Further studies are required to assess both clinical and cost effectiveness against the current gold standard (autologous graft).

Meta-Analysis Review
BACKGROUND
21 million pregnant women worldwide (18%) are estimated to carry Group B Streptococcus (GBS), which is a risk for invasive disease in newborns, pregnant women, and stillbirths. Adults ≥ 60 years or with underlying health conditions are also vulnerable to invasive GBS disease. We undertook systematic reviews on GBS organism characteristics including: capsular polysaccharide (serotype), sequence type (multi-locus sequence types (MLST)), and virulence proteins. We synthesised data by at-risk populations, to inform vaccine development.
METHODS
We conducted systematic reviews and meta-analyses to estimate proportions of GBS serotypes for at risk populations: maternal colonisation, invasive disease in pregnant women, stillbirths, infants 0-90 days age, and older adults (≥60 years). We considered regional variation and time trends (2001-2018). For these at-risk population groups, we summarised reported MLST and surface proteins.
RESULTS
Based on 198 studies (29247isolates), 93-99% of GBS isolates were serotypes Ia, Ib, II, III, IV and V. Regional variation is likely, but data gaps are apparent, even for maternal colonisation which has most data. Serotype III dominates for infant invasive disease (60%) and GBS-associated stillbirths (41%). ST17 accounted for a high proportion of infant invasive disease (41%; 95%CI: 35-47) and was found almost exclusively in serotype III strains, less present in maternal colonisation (9%; 95%CI:6-13),(4%; 95%CI:0-11) infant colonisation, and adult invasive disease (4%, 95%CI:2-6). Percentages of strains with at least one of alp 1, alp2/3, alpha C or Rib surface protein targets were 87% of maternal colonisation, 97% infant colonisation, 93% infant disease and 99% adult invasive disease. At least one of three pilus islands proteins were reported in all strains.
DISCUSSION
A hexavalent vaccine (serotypes Ia, Ib, II, III, IV and V) might provide comprehensive cover for all at-risk populations. Surveillance of circulating, disease-causing target proteins is useful to inform vaccines not targeting capsular polysaccharide. Addressing data gaps especially by world region and some at-risk populations (notably stillbirths) is fundamental to evidence-based decision-making during vaccine design.

OBJECTIVES
Child abuse is a significant cause of morbidity and mortality in preverbal children who cannot explain their injuries. Fractures are among the most common injuries associated with abuse but of themselves fractures may not be recognized as abusive until a comprehensive child abuse evaluation is completed, often prompted by other signs or subjective features. We sought to determine which children presenting with rib or long-bone fractures should undergo a routine abuse evaluation based on age.
METHODS
A systematic review searching Ovid, PubMed/Medline, Scopus, and CINAHL from 1980 to 2020 was performed. An evidence-based framework was generated by a consensus panel and applied to the results of the systematic review to form recommendations. Fifteen articles were suitable for final analysis.
RESULTS
Studies with comparable age ranges of subjects and sufficient evidence to meet the determination of abuse standard for pediatric patients with rib, humeral, and femoral fractures were identified. Seventy-seven percent of children presenting with rib fractures aged less than 3 years were abused; when those involved in motor vehicle collisions were excluded, 96% were abused. Abuse was identified in 48% of children less than 18 months with humeral fractures. Among those with femoral fractures, abuse was diagnosed in 34% and 25% of children aged less than 12 and 18 months, respectively.
CONCLUSION
Among children who were not in an independently verified incident, the authors strongly recommend routine evaluation for child abuse, including specialty child abuse consultation, for: 1) children aged less than 3 years old presenting with rib fractures and 2) children aged less than 18 months presenting with humeral or femoral fractures (Level of Evidence: III Review).

Meta-Analysis
OBJECTIVE
Thoracic outlet syndrome (TOS) is a complex disorder affecting the neurovascular structures of the upper extremity as they traverse from the neck and thorax to the upper extremity. This systematic review and meta-analysis focuses on pediatric TOS, offering insights into its clinical presentation, etiology, treatment modalities, and outcomes in contrast to those reported in adult TOS.
METHODS
A comprehensive search for pediatric TOS in the PubMed database using PRISMA guidelines identified 6 relevant studies published between 2008 and 2022. In total, 227 pediatric TOS cases in 216 patients were analyzed. Data categories explored for TOS in pediatric patients included study design, number of patients included, mean age and sex of patients, TOS type, laterality, bony abnormalities, time to surgery, symptoms, treatment modalities, initial surgical technique, surgical complications, percent lost to follow-up, mean follow-up period, and treatment outcome.
RESULTS
The results from the 6 studies of 216 patients show a distinct pattern in pediatric TOS, with a 1.84:1 female-to-male ratio, a mean age of 15.49 years, and a lower prevalence of neurogenic TOS (75%, 95% CI 0.41-0.93; I2 = 86%, p < 0.01) compared with the prevailing literature on adults (87.5%-99%). Venous and arterial TOS accounted for a higher proportion of cases in pediatric patients than in adults, challenging the traditional adult-oriented perspective. Right-sided presentations were more common, reflecting right-arm dominance in most individuals. Additionally, bony abnormalities were more common in adults (30%) than in children (10.65%). Treatments involved mixed methods, predominantly using combinations of muscle resection (95.26%), neurolysis (78.02%), and bone resection (72.41%). Patients had high rates of symptom improvement (89%, 95% CI 0.67-0.97; I2 = 85%, p < 0.01) following surgery, with improvement of symptoms ranging from slight to complete relief. Complications were infrequent (5.66%), and most patients reported positive outcomes. The limitations of this analysis include subjective diagnostic and reporting criteria for TOS given its broad range of presentations.
CONCLUSIONS
This systematic review and meta-analysis brings to light the distinctive characteristics of pediatric TOS and underscores the importance of recognizing these differences to ensure accurate diagnosis and effective treatment in this patient population. Further research is needed to understand the predictive value of conservative treatments, especially in pediatric TOS cases.

The vast majority of previous experimental studies on the thoracic spine were performed without the entire rib cage, while significant contributive aspects regarding stability and motion behavior were shown in several other studies. The aim of this literature review was to pool and increase evidence on the effect of the rib cage on human thoracic spinal biomechanical characteristics by collating and interrelating previous experimental findings in order to support interpretations of and studies disregarding the rib cage to create comparability and reproducibility for all studies including the rib cage and provide combined comparative data for future biomechanical studies on the thoracic spine. After a systematic literature search corresponding to PRISMA guidelines, eleven studies were included and quantitatively evaluated in this review. The combined data exhibited that the rib cage increases the thoracic spinal stability in all motion planes, primarily in axial rotation and predominantly in the upper thorax half, reducing thoracic spinal range of motion, neutral zone, and intradiscal pressure, while increasing thoracic spinal neutral and elastic zone stiffness, compression resistance, and, in a neutral position, the intradiscal pressure. In particular, the costosternal connection was found to be the primary stabilizer and an essential determinant for the kinematics of the overall thoracic spine, while the costotransverse and costovertebral joints predominantly reinforce the stability of the single thoracic spinal segments but do not alter thoracic spinal kinematics. Neutral zone and neutral zone stiffness were more affected by rib cage removal than the range of motion and elastic zone stiffness, thus also representing the essential parameters for destabilization of the thoracic spine. As a result, the rib cage and thoracic spine form a biomechanical entity that should not be separated. Therefore, usage of entire human non-degenerated thoracic spine and rib cage specimens together with pure moment application and sagittal curvature determination is recommended for future testing in order to ensure comparability, reproducibility, and quasi-physiological validity.

Meta-Analysis
OBJECTIVES
To review studies on deep learning (DL) models for classification, detection, and segmentation of rib fractures in CT data, to determine their risk of bias (ROB), and to analyse the performance of acute rib fracture detection models.
METHODS
Research articles written in English were retrieved from PubMed, Embase, and Web of Science in April 2023. A study was only included if a DL model was used to classify, detect, or segment rib fractures, and only if the model was trained with CT data from humans. For the ROB assessment, the Quality Assessment of Diagnostic Accuracy Studies tool was used. The performance of acute rib fracture detection models was meta-analysed with forest plots.
RESULTS
A total of 27 studies were selected. About 75% of the studies have ROB by not reporting the patient selection criteria, including control patients or using 5-mm slice thickness CT scans. The sensitivity, precision, and F1-score of the subgroup of low ROB studies were 89.60% (95%CI, 86.31%-92.90%), 84.89% (95%CI, 81.59%-88.18%), and 86.66% (95%CI, 84.62%-88.71%), respectively. The ROB subgroup differences test for the F1-score led to a p-value below 0.1.
CONCLUSION
ROB in studies mostly stems from an inappropriate patient and data selection. The studies with low ROB have better F1-score in acute rib fracture detection using DL models.
ADVANCES IN KNOWLEDGE
This systematic review will be a reference to the taxonomy of the current status of rib fracture detection with DL models, and upcoming studies will benefit from our data extraction, our ROB assessment, and our meta-analysis.

Meta-Analysis
The diagnostic performance of chest computed tomography in the detection of rib fractures in children investigated for suspected physical abuse: a systematic review and meta-analysis.
OBJECTIVES
To assess the diagnostic performance of chest CT in the detection of rib fractures in children investigated for suspected physical abuse (SPA).
METHODS
Medline, Web of Science and Cochrane databases were searched from January 1980 to April 2020. The QUADAS-2 tool was used to assess the quality of the eligible English-only studies following which a formal narrative synthesis was constructed. Studies reporting true-positive, false-positive, true-negative, and false-negative results were included in the meta-analysis. Overall sensitivity and specificity of chest CT for rib fracture detection were calculated, irrespective of fracture location, and were pooled using a univariate random-effects meta-analysis. The diagnostic accuracy of specific locations along the rib arc (anterior, lateral or posterior) was assessed separately.
RESULTS
Of 242 identified studies, 4 met the inclusion criteria. Of these, 2 were included in the meta-analysis. Chest CT identified 142 rib fractures compared to 79 detected by initial skeletal survey chest radiographs in live children with SPA. Post-mortem CT (PMCT) has low sensitivity (34%) but high specificity (99%) in the detection of rib fractures when compared to the autopsy reference standard. PMCT has low sensitivity (45%, 21% and 42%) but high specificity (99%, 97% and 99%) at anterior, lateral and posterior rib locations, respectively.
CONCLUSIONS
Chest CT detects more rib fractures than initial skeletal survey chest radiographs in live children with SPA. PMCT has low sensitivity but high specificity for detecting rib fractures in children investigated for SPA.
KEY POINTS
• PMCT has low sensitivity (34%) but high specificity (99%) in the detection of rib fractures; extrapolation to CT in live children is difficult. • No studies have compared chest CT with the current accepted practice of initial and follow-up skeletal survey chest radiographs in the detection of rib fractures in live children investigated for SPA.

Meta-Analysis
OBJECTIVE
The aim of the study was to assess the efficacy of different peripheral nerve blocks, compared to conventional methods (analgesics and epidural block), for pain relief in rib fracture patients.
MATERIALS AND METHODS
PubMed, Embase, Scopus and Cochrane Central Register of Controlled Trials (CENTRAL) databases were systematically searched. The review included studies that were either randomized controlled trials (RCTs) or observational in design with propensity matching. The primary outcome of interest was patient's reported pain scores, both at rest and on coughing/movement. The secondary outcomes were length of hospital stay, length of stay at intensive care unit (ICU), need for rescue analgesic, arterial blood gas values and parameters of lung function test. STATA was used for statistical analysis.
RESULTS
The meta-analysis was conducted with 12 studies. Compared to conventional methods, peripheral nerve block was associated with better pain control at rest 12 hours (SMD -4.89, 95% CI: -5.91, -3.86) and 24 hours (SMD -2.58, 95% CI: -4.40, -0.76) after institution of block. At 24 hours after block, the pooled findings indicate better pain control on movement/coughing for the peripheral nerve block group (SMD -0.78, 95% CI: -1.48, -0.09). There were no significant differences in the patient's reported pain scores at rest and on movement/coughing at 24 hours post-block. There were no differences in the overall risk of any complications (RR 0.48, 95% CI: 0.20, 1.18), pulmonary complication (RR 0.71, 95% CI: 0.35, 1.41) and in-hospital mortality (RR 0.62, 95% CI: 0.20, 1.90) between the two groups. Peripheral nerve block was also associated with a relatively lower need for rescue analgesic (SMD -0.31, 95% CI: -0.54, -0.07). There were no differences in the length of ICU and hospital stay, risk of complications, arterial blood gas values or functional lung parameters, i.e., PaO2 and forced vital capacity between the two management strategies.
CONCLUSIONS
Peripheral nerve blocks may be better than conventional pain management strategies for immediate pain control (within 24 hours of initiation of block) in patients with fractured ribs. This method also reduces the need for rescue analgesic. The skills and experience of the health personnel, facilities for care available and the cost involved should guide the decision on which management strategy to utilize.

Meta-Analysis
BACKGROUND
A comprehensive overview of treatments of common fractures is missing, although it would be important for shared decision-making in clinical practice. The aim was to determine benefits and harms of surgical compared to non-surgical treatments for traumatic skeletal fractures.
METHODS
We searched Medline, Embase, CINAHL, Web of Science, and CENTRAL until November 2018, for randomized trials of surgical treatment in comparison with or in addition to non-surgical treatment of fractures in adults. For harms, only trials with patient enrollment in 2000 or later were included, while no time restriction was applied to benefits. Two reviewers independently assessed studies for inclusion, extracted data from full-text trials, and performed risk of bias assessment. Outcomes were self-reported pain, function, and quality of life, and serious adverse events (SAEs). Random effects model (Hedges' g) was used.
RESULTS
Out of 28375 records screened, we included 61 trials and performed meta-analysis on 12 fracture types in 11 sites: calcaneus, clavicula, femur, humerus, malleolus, metacarpus, metatarsus, radius, rib, scaphoideum, and thoraco-lumbar spine. Seven other fracture types only had one trial available. For distal radius fractures, the standardized mean difference (SMD) was 0.31 (95% CI 0.10 to 0.53, n = 378 participants) for function, favoring surgery, however, with greater risk of SAEs (RR = 3.10 (1.42 to 6.77), n = 436). For displaced intra-articular calcaneus fractures, SMD was 0.64 (0.13 to 1.16) for function (n = 244) and 0.19 (0.01 to 0.36) for quality of life (n = 506) favoring surgery. Surgery was associated with a smaller risk of SAE than non-surgical treatment for displaced midshaft clavicular fractures (RR = 0.62 (0.42 to 0.92), n = 1394). None of the other comparisons showed statistical significance differences and insufficient data existed for most of the common fracture types.
CONCLUSIONS
Of 12 fracture types with more than one trial, only two demonstrated a difference in favor of surgery (distal radius fractures and displaced intra-articular calcaneus fractures), one of which demonstrated a greater risk of harms in the surgical group (distal radius fractures). Our results highlight the current paucity of high-quality randomized trials for common fracture types and a considerable heterogeneity and risk of bias in several of the available trials.
