OBJECTIVES
Multiple systematic reviews have reported on the impact of rib fracture fixation in the presence of flail chest and multiple rib fractures, however this practice remains controversial. Our aim is to synthesise the effectiveness of surgical rib fracture fixation as evidenced by systematic reviews.
DESIGN
A systematic search identified systematic reviews comparing effectiveness of rib fracture fixation with non-operative management of adults with flail chest or unifocal non-flail rib fractures. MEDLINE, EMBASE, Cochrane Database of Systematic Reviews and Science Citation Index were last searched 17 March 2017. Risk of bias was assessed using the Risk Of Bias In Systematic reviews (ROBIS) tool. The primary outcome was duration of mechanical ventilation.
RESULTS
Twelve systematic reviews were included, consisting of 3 unique randomised controlled trials and 19 non-randomised studies. Length of mechanical ventilation was shorter in the fixation group compared with the non-operative group in flail chest; pooled estimates ranged from -4.52 days, 95% CI (-5.54 to -3.5) to -7.5 days, 95% CI (-9.9 to -5.5). Pneumonia, length of hospital and intensive care unit stay all showed a statistically significant improvement in favour of fixation for flail chest; however, all outcomes in favour of fixation had substantial heterogeneity. There was no statistically significant difference between groups in mortality. Two systematic reviews included one non-randomised studies of unifocal non-flail rib fracture population; due to limited evidence the benefits with surgery are uncertain.
CONCLUSIONS
Synthesis of the reviews has shown some potential improvement in patient outcomes with flail chest after fixation. For future review updates, meta-analysis for effectiveness may need to take into account indications and timing of surgery as a subgroup analysis to address clinical heterogeneity between primary studies. Further robust evidence is required before conclusions can be drawn of the effectiveness of surgical fixation for flail chest and in particular, unifocal non-flail rib fractures.

Review
BACKGROUND CONTEXT
Traumatic spinal injuries often require surgical fixation. Specific three-dimensional degrees of instability after spinal injury, which represent criteria for optimum treatment concepts, however, are still not well investigated.
PURPOSE
The aim of this review therefore was to summarize and quantify multiplanar instability increases due to spinal injury from experimental studies.
STUDY DESIGN/SETTING
Systematic review.
METHODS
A systematic review of the literature was performed using keyword-based search on PubMed and Web of Science databases in order to detect all in vitro studies investigating the destabilizing effect of simulated and provoked traumatic injury in human spine specimens. Together with the experimental designs, the instability parameters range of motion, neutral zone and translation were extracted from the studies and evaluated regarding type and level of injury.
RESULTS
A total of 59 studies was included in this review, of which 43 studies investigated the effect of cervical spine injury. Range of motion increase, which was reported in 58 studies, was generally lower compared to the neutral zone increase, given in 37 studies, despite of injury type and level. Instability increases were highest in flexion/extension for most injury types, while axial rotation was predominantly affected after cervical unilateral dislocation injury and lateral bending solely after odontoid fracture. Whiplash injuries and wedge fractures were found to increase instability equally in all motion planes.
CONCLUSIONS
Specific traumatic spinal injuries produce characteristic but complex three-dimensional degrees of instability, which depend on the type, level, and morphology of the injury. Future studies should expand research on the cervicothoracic, thoracic, and lumbosacral spine and should additionally investigate the destabilizing effects of the injury morphology as well as concomitant rib cage injuries in case of thoracic spinal injuries. Moreover, neutral zone and translation should be measured in addition to the range of motion, while mechanical injury simulation should be preferred to resection or transection of structures to ensure high comparability with the clinical situation.

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
The potential benefit of ultrasonography for detection of thoracic bone fractures has been proven in various surveys but no comprehensive conclusion has been drawn yet; therefore, the present study aimed to conduct a thorough meta-analytic systematic review on this subject.
METHODS
Two reviewers independently carried out a comprehensive systematic search in Medline, EMBASE, ISI Web of Knowledge, Scopus, Cochrane Library, and ProQuest databases. Data were summarized as true positive, false positive, true negative and false negative and were analyzed via STATA 11.0 software using a mixed-effects binary regression model. Sources of heterogeneity were further assessed through subgroup analysis.
RESULTS
Data on 1667 patients (807 subjects with and 860 cases without thoracic fractures), whose age ranged from 0 to 92 years, were extracted from 17 surveys. Pooled sensitivity and specificity of ultrasonography in detection of thoracic bone fractures were 0.97 (95% CI: 0.90-0.99; I2= 88.88, p<0.001) and 0.94 (95% CI: 0.86-0.97; I2= 71.97, p<0.001), respectively. The same measures for chest radiography were found to be 0.77 (95% CI: 0.56-0.90; I2= 97.76, p<0.001) and 1.0 (95% CI: 0.91-1.00; I2= 97.24, p<0.001), respectively. The sensitivity of ultrasonography was higher in detection of rib fractures, compared to fractures of sternum or clavicle (97% vs. 91%). Moreover, the sensitivity was found to be higher when the procedure was carried out by a radiologist in comparison to an emergency medicine specialist (96% vs. 90%).
CONCLUSION
Base on the findings of the present meta-analysis, screening performance characteristic of ultrasonography in detection of thoracic bone fractures was found to be higher than radiography. However, these characteristics were more prominent in detection of rib fractures and in cases where was performed by a radiologist.

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.

Meta-Analysis Review
PURPOSE
Thoracoplasty is a procedure which involves rib resection from the costovertebral junction to the apex of the rib hump deformity to address the cosmetic concerns of patients of scoliosis. There is conflicting literature on its effect on pulmonary function. The present meta-analysis was conducted to review and analyze the available literature and ascertain the effect of thoracoplasty on pulmonary function.
METHODS
Search was conducted according to PRISMA guidelines on three databases. After analysis of all the search results by title, abstracts and full texts-10 studies were identified for inclusion in the review. We included studies which had analyzed preoperative and postoperative pulmonary function tests (PFTs) after thoracoplasty. Pooled estimates were calculated for pulmonary function, and effect of other factors was analyzed by subgroup analysis and meta-regression.
RESULTS
The included studies were published between 1998 and 2019. A total of 385 patients were included in these studies, with a mean age of 15.01 years, with a female preponderance. Apprehension over appearance of rib hump was the most common indication for thoracoplasty. Percent-predicted forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV-1) were significantly decreased on follow-up. Anterior approach to corrective surgery and lower age were found to be associated with worse pulmonary function. Preoperative Cobb's angle was found to have significant impact on decrease in FEV-1 only, but not on other PFT parameters.
CONCLUSION
Overall decrease in pulmonary function after thoracoplasty necessitates the need of adequate preoperative pulmonary function to mitigate its effect on patient well-being. Use of a posterior approach for corrective surgery when thoracoplasty is planned might lead to better outcomes. More research is needed to study effect of preoperative Cobb's angle on pulmonary function.

Meta-Analysis Review
BACKGROUND
Many epidemiological studies have examined associations between birth defects (BDs) and pediatric malignancy over the past several decades. Our objective was to conduct a systematic literature review of studies reporting on this association.
METHODS
We used librarian-designed searches of the PubMed Medline and Embase databases to identify primary research articles on pediatric neoplasms and BDs. English language articles from PubMed and Embase up to 10/12/2015, and in PubMed up to 5/12/2017 following an updated search, were eligible for inclusion if they reported primary epidemiological research results on associations between BDs and pediatric malignancies. Two reviewers coded each article based on the title and abstract to identify eligible articles that were abstracted using a structured form. Additional articles were identified through reference lists and other sources. Results were synthesized for pediatric cancers overall and for nine major pediatric cancer subtypes.
RESULTS
A total of 14,778 article citations were identified, of which 80 met inclusion criteria. Pediatric cancer risk was increased in most studies in association with BDs overall with some notable specific findings, including increased risks for CNS tumors in association with CNS abnormalities and positive associations between rib anomalies and several pediatric cancer types.
CONCLUSIONS
Some children born with BDs may be at increased risk for specific pediatric malignancy types. This work provides a foundation for future investigations that are needed to clarify specific BD types predisposing toward malignancy and possible underlying causes of both BDs and malignancy.

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.
