Rib fracture as a predictor of future fractures in young and older postmenopausal women: National Osteoporosis Risk Assessment (NORA)

Summary  

A rib fracture history after age 45 was associated with a 5.4-fold increase in new rib fracture risk and a 2.4-fold increase in risk of any new clinical fracture in 155,031 postmenopausal women. A rib fracture history suggests osteoporosis and should be considered when evaluating patients for interventions to prevent fractures.     

Ultrasonographic evaluation of costal cartilage fractures unnoticed by the conventional radiographic study and multidetector computed tomography

Introduction  

Rib fractures are the most common injuries resulting from blunt chest trauma. However, costal cartilage fractures are almost invisible on chest X-rays unless they involve calcified cartilage. The sensitivity of conventional radiography and computed tomography for detecting rib fractures is limited, especially in cases where rib cartilage is involved. Therefore, this study was designed to evaluate the sensitivities of chest wall ultrasonography, clinical findings, and radiography in the detection of costal cartilage fractures.     

Biomechanical rationale and evaluation of an implant system for rib fracture fixation

Background  

Biomechanical research directed at developing customized implant solutions for rib fracture fixation is essential to reduce the complexity and to increase the reliability of rib osteosynthesis. Without a simple and reliable implant solution, surgical stabilization of rib fractures will remain underutilized despite proven benefits for select indications. This article summarizes the research, development, and testing of a specialized and comprehensive implant solution for rib fracture fixation.     

An Innovative Model of ISS-Based Multiple Fractures and Gastrointestinal Dysfunction Related to c-Kit Protein Expression on Interstitial Cells of Cajal

Objective

Gastrointestinal dysfunction seriously affects the prognosis and quality of life of patients with multiple fractures. However, experimental evidence of this relationship is lacking. Here we describe a newly developed mouse model of postoperative gastrointestinal dysfunction after multiple fractures.

Methods

Trauma severity was assessed using the injury severity score (ISS). Based on the ISS, a multiple fracture model was established in mice as follows: limb fractures with pelvic fractures and multiple rib fractures; limb fractures with multiple rib fractures; closed fracture of both forelegs with pelvic fracture and rib fractures; closed limb fractures; limb fracture with pelvic fracture; spinal fractures; hind leg fractures with pelvic fractures; pelvic fracture with multiple rib fractures; closed fracture of both fore legs with pelvic fracture; and closed fracture of both fore legs with multiple rib fractures. In each model group, gastrointestinal motility was assayed and the histopathology of the small intestine was examined. Western blot and immunohistochemical analyses of jejunal tissue were performed to detect c-kit protein expression, the level of which was compared with that of a control group. The results of ANOVA are expressed as mean ± standard deviation.

Results

In mice with multiple fractures, food intake was greatly reduced, consistent with histopathological evidence of an injured intestinal epithelium. The jejunal tissue of mice in groups a, c, f, and h was characterized by extensively necrotic and exfoliated intestinal mucosal epithelium and inflammatory cell infiltration in the lamina propria. In the gastrointestinal function assay, gastrointestinal motility was significantly reduced in groups a, b, c, f, and g; these group also had a higher ISS (p < 0.01). The expression of c-kit protein in groups with gastrointestinal dysfunction was significantly up-regulated (p < 0.001) compared with the control group. The close correlation between c-kit expression and the ISS indicated an influence of trauma severity on gastrointestinal motility.

Conclusion

Gastrointestinal dysfunction after multiple fractures was successfully reproduced in a mouse model. In these mice, c-kit expression correlated with gastrointestinal tissue dysfunction and might serve as a therapeutic target.

Stabilization of multiple rib fractures in a canine model

Background

Operative stabilization is frequently used in the clinical treatment of multiple rib fractures (MRF); however, no ideal material exists for use in this fixation. This study investigates a newly developed biodegradable plate system for the stabilization of MRF.

Methods

Silk fiber-reinforced polycaprolactone (SF/PCL) plates were developed for rib fracture stabilization and studied using a canine flail chest model. Adult mongrel dogs were divided into three groups: one group received the SF/PCL plates, one group received standard clinical steel plates, and the final group did not undergo operative fracture stabilization (n = 6 for each group). Radiographic, mechanical, and histologic examination was performed to evaluate the effectiveness of the biodegradable material for the stabilization of the rib fractures.

Results

No nonunion and no infections were found when using SF-PCL plates. The fracture sites collapsed in the untreated control group, leading to obvious chest wall deformity not encountered in the two groups that underwent operative stabilization.

Conclusions

Our experimental study shows that the SF/PCL plate has the biocompatibility and mechanical strength suitable for fixation of MRF and is potentially ideal for the treatment of these injuries.     

The significance of first rib fractures in children

Purpose

The purpose of the study was to determine if first rib fractures are associated with an increased incidence of thoracic vascular injury in pediatric patients.

Methods

The medical records of all children diagnosed with a first rib fracture or a central vascular injury after blunt trauma treated at a state-designated level 1 pediatric trauma center from 2000 to 2009 were reviewed.

Results

Thirty-three children (0.27% of patients; mean age, 10.9 ± 0.9 years) were identified with either a first rib fracture or thoracic vascular injury owing to blunt trauma. Thirty-two children had a first rib fracture, and only 1 child (3%) had significant thoracic vascular injury. Mediastinal abnormalities (indistinct aortic knob) were identified in 3 children, 2 with first rib fracture on initial chest radiograph. Despite a normal cardiovascular examination result, 25 (74%) children with a normal mediastinum on screening chest radiograph underwent computed tomography. No child with a normal mediastinum on initial chest radiograph was found to have associated intrathoracic injuries requiring further intervention. In children with first rib fractures and a normal mediastinum by screening chest x-ray, the negative predictive value for thoracic vascular injury was 100%.

Conclusions

Children with first rib fractures without mediastinal abnormality on chest radiograph require no further workup for thoracic vascular injury.     

Rib stabilization: lessons learned

Introduction

The management of rib fractures and flail chest has changed considerably over the past century, and recently there has been a renewed interest in operative rib stabilization for these injuries. Despite numerous reports suggesting improved outcomes with rib stabilization, there are not well-defined indications and the approach remains somewhat controversial.

Materials and methods

The authors reflect on their experience of performing rib stabilization in over 100 patients with rib fractures and flail chest.

Conclusion

The authors offer their opinions on this operation with respect to rationale, indications, timing, technique, and postoperative care.     

Impact of rib fixation on quality of life after major trauma with multiple rib fractures

Introduction

Multiple rib fractures have been shown to reduce quality of life both in the short and long term. Treatment of rib fractures with operative fixation reduces ventilator requirements, intensive care unit stay, and pulmonary complications in flail chest patients but has not been shown to improve quality of life in comparative studies to date. We therefore wanted to analyse a large cohort of multiple fractured rib trauma patients to see if rib fixation improved their quality of life.

Use of ketorolac is associated with decreased pneumonia following rib fractures

Background

The effectiveness of the nonsteroidal anti-inflammatory drug ketorolac in reducing pulmonary morbidity after rib fractures remains largely unknown.

Methods

A retrospective cohort study was conducted spanning January 2003 to June 2011 assessing pneumonia within 30 days and potential adverse effects of ketorolac among all patients with rib fractures who received ketorolac <4 days after injury compared with a random sample of those who did not.

Results

Among 202 patients who received ketorolac and 417 who did not, ketorolac use was associated with decreased pneumonia (odds ratio, .14; 95% confidence interval, .04 to .46) and increased ventilator-free days (difference, 1.8 days; 95% confidence interval, 1.1 to 2.5) and intensive care unit–free days (difference, 2.1 days; 95% confidence interval, 1.3 to 3.0) within 30 days. The rates of acute kidney injury, gastrointestinal hemorrhage, and fracture nonunion were not different.

Conclusions

Early administration of ketorolac to patients with rib fractures is associated with a decreased likelihood of pneumonia, without apparent risks.

RIB fracture triage pathway decreases ICU utilization,pulmonary complications and hospital length of stay

IntroductionRib fractures are one of the most frequent causes of morbidity following blunt injury to the chest. Many of these patients require ICU care and often develop pulmonary complications. Prior studies have attempted to identify changes in predicted lung volumes or utilized the number of rib fractures to guide clinical decisions. A rib fracture triage pathway was developed to identify which patients will benefit from ICU level of care and shorten hospital length of stay for patients that do not require ICU care.MethodsThe triage pathway utilized patient's age, number of rib fractures, significant cardiopulmonary co-morbidities, and incentive spirometry volumes to determine admission disposition. The triage pathway was implemented on November 2016. All patients with rib fractures from November 2015 to 2017 were identified in the trauma registry. Data was collected on patients age, gender, Glasgow Coma Scale on arrival (GCS), injury severity score (ISS), number of rib fractures, incentive spirometry volumes, days in intensive care (ICU), ventilator days, length of stay (LOS), complications, and mortality. Patients with severe TBI, those arriving intubated, or died within 48 h were excluded. The patients remaining were 278 patients in the pre triage pathway group and 370 in the post triage pathway.ResultsThere was no difference in age, gender, GCS, ISS, predicted incentive spirometry or number of rib fractures. The post treatment patients required significantly lower ICU admissions (64% vs 75%, p = 0.003), significantly lower pulmonary complication (5.1% vs 10.4%, p = 0.01), and significantly shorter hospital length of stay (6.8 d vs 7.5, p = 0.001) with no difference in mortality (1.6% vs 2.5%, p = 0.42) or readmission (0.3% vs. 0.7%, p = 0.4). Patient post triage protocol were also more likely to be discharge home (81% vs 70%, p = 0.0009) with less patients going to a skilled nursing facility (13% vs 21%, p = 0.01).ConclusionsDeveloping a rib fracture treatment and triage pathway can decrease ICU and hospital resource utilization and decrease pulmonary complications without increase in readmissions or mortality. Patients are more likely to be discharge home over a skilled nursing facility further decreasing health care cost. Level of Evidence IV Retrospective Study, Prognostic     

Medial scapular winging associated with rib fractures and plating corrected with pectoralis major transfer

INTRODUCTION

Rib plating is becoming increasingly common as a method for stabilizing a flail chest resulting from multiple rib fractures. Recent guidelines recommend surgical stabilization of a flail chest based on consistent evidence of its efficacy and lack of major safety concerns. But complications of this procedure can occur and are wide ranging.

PRESENTATION OF CASE

We report an interesting case of a 58-year-old male patient that worked as a long-distance truck driver and had a flail chest from multiple bilateral rib fractures that occurred when his vehicle was blown over in a wind storm. He underwent open reduction with internal fixation (ORIF) of the bilateral rib fractures and they successfully healed. However, he had permanent long thoracic nerve injury on the side with the most severe trauma. This resulted in symptomatic scapular winging that impeded him from long-distance truck driving. The scapular winging was surgically corrected nearly two years later with a pectoralis major transfer augmented with fascia lata graft. The patient had an excellent final result.

DISCUSSION

We report this case to alert surgeons who perform rib fracture ORIF that long thoracic nerve injury is a potential iatrogenic complication of that procedure or might be a result of the chest wall trauma.

CONCLUSION

Although the specific cause of the long thoracic nerve injury could not be determined in our patient, it was associated with chest wall trauma in the setting of rib fracture ORIF. The scapular winging was surgically corrected with a pectoralis major transfer.
