Assessing the true risk of abdominal solid organ injury in hospitalized rib fracture patients

BACKGROUND: Despite the lack of evidence, traditional trauma teaching has suggested that low rib fractures increase the risk of abdominal solid organ injury (ASOI). This study was designed to assess if in fact this is true, and to try and define other factors that increased the risk of ASOI in rib fracture patients. METHODS: The charts of 476 hospitalized rib fracture trauma patients were reviewed. Data were collected for age; sex; Injury Severity Score (ISS); rib fracture location; and the presence or absence of injuries to the abdominal organs, head, neck, face, thorax, great vessel, heart, thoracolumbar spine, pelvis, and extremities. RESULTS: The probability of liver injury increased with the presence of any right-sided rib fracture, any low rib fracture, female gender, young age, and an elevated ISS. The probability of splenic injury increased with the presence of left-sided rib fractures only, any low rib fracture, young age, and an elevated ISS. CONCLUSION: In hospitalized trauma patients, low rib fractures, right-sided rib fractures, female gender, young age, and an elevated ISS increased the probability of liver injury; and low rib fractures, left-sided only rib fractures, young age, and an elevated ISS increased the probability of splenic injury. Associated pelvic fractures and long bone fractures did not increase the likelihood of ASOI in this cohort.     

THE SIGNIFICANCE OF FIRST AND SECOND RIB FRACTURES*

There are differing opinions in the literature regarding the significance of first rib fractures. The plan at Westmead Centre is to standardize the initial assessment of patients with such fractures. A 3 year retrospective study of 170 trauma victims who sustained fractured ribs, was undertaken. Of the 15 patients with first rib fracture, all were involved in motor vehicle accidents. Over two-thirds of these patients sustained major chest injuries. Multisystem trauma involving cranial, abdominal or skeletal injury was common. One patient died as a result of head injury. Similar results were observed in 13 patients with second rib fractures. Brachial plexus injuries were noted in two patients with first rib fracture. Despite follow-up of high-risk patients at an interval which varied from 1 to 2½ years after the original injury, major subclavian artery injury was not detected in patients with first rib fracture. From this experience and a literature review, we suggest that the general nature of trauma is similar in patients with first rib fracture to that in patients with second rib fracture. Patients with first rib fracture should be closely examined for neurovascular compromise. Guidelines for the use of angiography are discussed. If there is no evidence of neurovascular injury at presentation, and there is no other thoracic injury, recovery should be uneventful.     

Chest injury due to blunt trauma.

OBJECTIVE: Given its importance in trauma practice, we aimed to determine the pathologies associated with blunt chest injuries and to analyze the accurate identification of patients at high risk for major chest trauma. METHODS: We reviewed our experience with 1490 patients with blunt chest injuries who were admitted over a 2-year period. Patients were divided into three groups based on the presence of rib fractures. The groups were evaluated to demonstrate the relationship between the number of rib fractures and associated injuries. The possible effects of age and Injury Severity Score (ISS) on mortality were analyzed. RESULTS: Mean hospitalization time was 4.5 days. Mortality rate was 1% for the patients with blunt chest trauma, 4.7% in patients with more than two rib fractures and 17% for those with flail chest. There was significant association between the mortality rate and number of rib fractures, the patient's age and ISS. The rate of development of pneumothorax and/or hemothorax was 6.7% in patients with no rib fracture, 24.9% in patients with one or two rib fractures and 81.4% in patients with more than two rib fractures. The number of rib fractures was significantly related with the presence of hemothorax or pneumothorax. CONCLUSION: Achieving better results in the treatment of patients with chest wall injury depend on a variety of factors. The risk of mortality was associated with the presence of more than two rib fractures, with patients over the age of 60 years and with an ISS greater than or equal to 16 in chest trauma. Those patients at high risk for morbidity and mortality and the suitable approach methods for them should be acknowledged.     

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.     

Disclosure of unnoticed rib fractures with the use of ultrasonography in minor blunt chest trauma.

OBJECTIVE: Rib fractures are the most common injuries resulting from blunt chest trauma. The sensitivity of chest X-rays in showing the rib fractures is limited particularly in those involving the cartilage part of the rib. We investigated the possible rib fractures, those overlooked on chest X-rays, with the use of ultrasonography in minor blunt chest trauma. METHODS: A total of 37 patients, with minor blunt chest trauma showing no evidence of a rib fracture on chest X-rays, were examined with ultrasonography performed with a 7.5-MHz linear transducer. Logistic regression analysis was done to outline the clinical predictors of these insidious rib fractures. RESULTS: A total of 15 (40.5%) patients showed rib lesions, whereas 22 (59.5%) patients had no evidence of rib lesions. Fracture of the rib associated with a subperiosteal hematoma was the most common finding in ten (66.7%) patients followed by the fracture of the rib alone in four (26.7%) patients, and subperiosteal hematoma alone in one (6.7%) patient. A total of eight (53.3%) patients had bony rib fractures, whereas seven (46.7%) patients had chondral rib fractures. Age (P=0.617), gender (P=0.552), type of etiology (P=0.954), duration of pain (P=0.234) and site of trauma (P=0.740) did not appear as significant predictors for these rib fractures. However, the involved part of the rib showed a significant correlation with either age (P=0.042) or duration of pain (P=0.033). Bony rib fractures significantly occurred in elderly patients, and the duration of pain in patients with bony rib fractures was significantly longer than that of patients with chondral rib fractures. CONCLUSIONS: Ultrasonography is a useful imaging method in showing the rib fractures those overlooked on chest X-rays in minor blunt chest trauma, and no significant clinical feature exists as a predictor for these insidious fractures. However, bony rib fractures significantly occur in elderly patients and result in a longer duration of pain.     

A comprehensive analysis of traumatic rib fractures: morbidity, mortality and management.

OBJECTIVE: A rib fracture secondary to blunt thoracic trauma is an important indicator of the severity of the trauma. In the present study we explored the morbidity and mortality rates and the management following rib fractures. METHODS: Between May 1999 and May 2001, 1417 cases who presented to our clinic for thoracic trauma were reviewed retrospectively. Five hundred and forty-eight (38.7%) of the cases had rib fracture. There were 331 males and 217 females, with an overall mean age of 43 years (range: 5-78 years). These patients were allocated into groups according to their ages, the number of fractured ribs and status, i.e. whether they were stable or unstable (flail chest). RESULTS: The etiology of the trauma included road traffic accidents in 330 cases, falls in 122, assault in 54, and industrial accidents in 42 cases. Pulmonary complications such as pneumothorax (37.2%), hemothorax (26.8%), hemo-pneumothorax (15.3%), pulmonary contusion (17.2%), flail chest (5.8%) and isolated subcutaneous emphysema (2.2%) were noted. 40.1% of the cases with rib fracture were treated in intensive care units. The mean duration of their stay in the intensive care unit was 11.8+/-6.2 days. 42.8% of the cases were treated in the wards whereby their mean duration of hospital stay was 4.5+/-3.4 days, while 17.1% of the cases were followed up in the outpatient clinic. Twenty-seven patients required surgery. Mortality rate was calculated as 5.7% (n=31). CONCLUSIONS: Rib fractures can be interpreted as signs of significant trauma. The greater the number of fractured ribs, the higher the mortality and morbidity rates. Patients with isolated rib fractures should be hospitalized if the number of fractured ribs is three or more. We also advocate that elderly patients with six or more fractured ribs should be treated in intensive care units due to high morbidity and mortality.     

Accuracy of chest radiography versus chest computed tomography in hemodynamically stable patients with blunt chest trauma

Objective：Thoracic injuries are responsible for 25% of deaths of blunt traumas.Chest X-ray （CXR） is the first diagnostic method in patients with blunt trauma.The aim of this study was to detect the accuracy of CXR versus chest computed tomograpgy （CT） in hemodynamically stable patients with blunt chest trauma.Methods：Study was conducted at the emergency department of S ina Hospital from March 2011 to March 2012.Hemodynamically stable patients with at least 16 years of age who had blunt chest trauma were included.All patients underwent the same diagnostic protocol which consisted of physical examination,CXR and CT scan respectively.Results：Two hundreds patients （84% male and 16% female） were included with a mean age of（37.9±13.7） years.Rib fracture was the most common finding of CXR （12.5%） and CT scan （25.5%）.The sensitivity of CXR for hemothorax,thoracolumbar vertebra fractures and rib fractures were 20%,49% and 49%,respectively.Pneumothorax,foreign body,emphysema,pulmonary contusion,liver hematoma and sternum fracture were not diagnosed with CXR alone.Conclusion：Applying CT scan as the first-line diagnostic modality in hemodynamically stable patients with blunt chest trauma can detect pathologies which may change management and outcome.     

The significance of first and second rib fractures

There are differing opinions in the literature regarding the significance of first rib fractures. The plan at Westmead Centre is to standardize the initial assessment of patients with such fractures. A 3 year retrospective study of 170 trauma victims who sustained fractured ribs, was undertaken. Of the 15 patients with first rib fracture, all were involved in motor vehicle accidents.

Similar results were observed in 13 patients with second rib fractures. Brachial plexus injuries were noted in two patients with first rib fracture. Despite follow-up of high-risk patients at an interval which varied from 1 to 2 1/2 years after the original injury, major subclavian artery injury was not detected in patients with first rib fracture. From this experience and a literature review, we suggest that the general nature of trauma is similar in patients with first rib fracture to that in patients with second rib fracture. Patients with first rib fracture should be closely examined for neurovascular compromise. Guidelines for the use of angiography are discussed. If there is no evidence of neurovascular injury at presentation, and there is no other thoracic injury, recovery should be uneventful.     

Morbidity from rib fractures increases after age 45

BACKGROUND: Recent studies have demonstrated increased morbidity in elderly patients with rib fractures after blunt trauma. As a first step in creating a multidisciplinary rib fracture clinical pathway, we sought to determine the relationship between increasing age, number of rib fractures, and adverse outcomes in blunt chest trauma patients, without major abdominal or brain injury. STUDY DESIGN: We performed a retrospective cohort study involving all blunt patients greater than 15 years old with rib fractures, excluding those with Abbreviated Injury Scores (AIS) greater than 2 for abdomen and head, admitted to an urban Level I trauma center during 20 months. Outcomes parameters included the number of rib fractures, Injury Severity Score (ISS), intrathoracic injuries, pulmonary complications, number of ventilator days, length of stay in the intensive care unit (ICU), hospital stay, and type of analgesia. RESULTS: Of the 6,096 patients admitted, 171 (2.8%) met the inclusion criteria. Based on an analysis of increasing age, number of rib fractures, and adverse outcomes variables, patients were separated into four groups: group 1, 15 to 44 years old with 1 to 4 rib fractures; group 2, 15 to 44 years old with more than 4 rib fractures; group 3, 45 years or older with 1 to 4 rib fractures; and group 4, 45 years or more with more than 4 rib fractures. The four groups had similar numbers of pulmonary contusions (30%) and incidence of hemopneumothorax (51%). Ventilator days (5.8 +/- 1.8), ICU days (7.5 +/- 1.8), and total hospital stay (14.0 +/- 2.2) were increased in group 4 patients compared with the other groups (p < 0.05). Epidural analgesia did not affect outcomes. Overall mortality was 2.9% and was not different between groups. CONCLUSIONS: Patients over the age of 45 with more than four rib fractures are more severely injured and at increased risk of adverse outcomes. Efforts to decrease rib fracture morbidity should focus not only on elderly patients but those as young as 45 years. Based on these data we have initiated a multidisciplinary clinical pathway focusing on patients 45 years and older who have more than four rib fractures.     

The significance of scapular fractures

Scapular fractures in the multiply injured patient have received little attention. Fifty-six patients with 58 scapular fractures secondary to blunt trauma were reviewed. The patients averaged 3.9 major injuries excluding their scapular fractures. The injury pattern associated with blunt scapular fracture is unique. Patients with scapular fracture have a high incidence of injury to the ipsilateral lung and chest wall and to the ipsilateral shoulder girdle and its contained structures: rib fractures, 53.6%; pulmonary contusions, 53.6%; clavicular fracture, 26.8%; brachial plexus injury, 12.5%; subclavian, brachial, or axillary artery injury, 10.7%. Eight patients died (14.3%). Although no patient died from the scapular fracture, half of the deaths in this series were the result of pulmonary sepsis arising in an associated ipsilateral pulmonary contusion. Scapular fractures provide the trauma surgeon with a reliable clinical clue that the patient is at inordinate risk to have associated injuries of major consequence to the ipsilateral lung and chest wall, the ipsilateral shoulder girdle, and the ipsilateral subclavian, axillary, or brachial artery.

Rib fracture healing in experimental flail chest

Sixteen dogs were placed under general anesthesia and flail segments of the left chest were created by transecting ribs 7,8,9, and 10 anteriorly and posteriorly. Fractures were 10 cm apart so that a 10-cm flail segment encompassing four ribs was created. In Group I, the control (N = 5), the chest wall muscles were closed without any stabilization of the fractures. Group II (N = 5) had stabilization of both anterior and posterior fracture sites by polypropylene sutures. Group III (N = 6) had stabilization of the fractures in ribs 7 and 8 with 2.5-cm bone grafts taken from the left fourth rib. Ribs 9 and 10 were stabilized by polypropylene sutures. The study established a canine model for flail chest. It also showed that strut stabilization of rib fractures with bone grafts promotes better healing than suture stabilization. It suggests that using bone grafts taken from another rib to stabilize flail segments may be unsatisfactory since the rib used as a donor showed no signs of regeneration at 30 days.     

RIB FRACTURES IN MAJOR TRAUMA

Background: To determine the mortality, hospital and intensive care unit (ICU) stay of rib fractures in patients admitted to Victorian hospitals for more than 1 day. Methods: All patients fitting the entry criteria for the Victorian Major Trauma Study with fractured ribs were identified between 1 March 1992 and 28 February 1993. Aetiology, age, sex, associated injury and outcome were analysed. Results: Patients with rib fractures had a higher mortality and length of hospital stay, but this was not significantly different from other trauma. A significantly higher percentage of patients required ICU care for rib fractures (44%) compared with the total group with blunt injury (24%). The majority of rib fractures resulted from motor vehicle accidents 361/541 (67%). Injuries occurring on the street/highway resulting in rib fractures were more likely to be major; 62% had Injury Severity Score (ISS) > 15. Fractured ribs occurred more commonly with increased age. Mortality for patients with fractured ribs versus total trauma group was higher in elderly patients. Univariate analysis showed rib fractures were a positive predictor of death but when adjusted for ISS and age, rib fractures became a negative predictor. Rib fractures were not predictors for length of ICU or hospital stay. Conclusion: The sample of rib fractures collected in this study underestimates the overall incidence. For those patients admitted to hospital with identified rib fractures, there is a trend towards higher mortality and morbidity. However, this association is better predicted by ISS and age.     

Chest injuries in childhood.

Differences in anatomy and mechanisms of injury are believed to contribute to the unique response of children to thoracic trauma. To characterize the scope and consequences of childhood chest injury, we reviewed the records of 105 children (ages 1 month to 17 years, mean 7.6 years) with chest injuries admitted to a level I pediatric trauma center from 1981 to 1988. Nearly all injuries (97.1%) were due to blunt trauma, and more than 50% were traffic related. Rib fractures, commonly multiple, and pulmonary contusions occurred with nearly equal frequency (49.5% and 53.3%, respectively), followed by pneumothorax (37.1%) and hemothorax (13.3%). One fourth of all pneumothoraces were under tension. Significant intrathoracic injuries occurred without rib fractures in 52% of cases with blunt trauma. Associated head, abdominal, and orthopedic injuries were present in 68.6% of children reviewed. One in five received endotracheal intubation and ventilatory support for 1 to 109 days. Presence or absence of head injury neither increased the need for respiratory support (29.4% vs. 17.2%, respectively; p = 0.24) nor affected the duration of support for those who were ventilated (6.8 +/- 8.9 days vs. 3.3 +/- 2.6 days, excluding one ventilator-dependent head-injured patient and five early deaths). The presence of associated injuries, intubation, and pneumothorax or hemothorax all resulted in significantly longer hospitalizations and more severe injury as measured by Injury Severity Score (ISS). Age, rib fracture, and contusion had no effect. Rarely encountered were ruptured diaphragm (2 cases), transection of the aorta (1), major tracheobronchial tears (3), flail chest (1), and cardiac contusion (2). Only two of the three children with penetrating injuries and three of the 83 (3.6%) with blunt injuries underwent chest operations. Six children (7%) died, one from a penetrating injury and five from blunt mechanisms. Chest Abbreviated Injury Scale (AIS) and ISS correlated significantly with mortality; age and head AIS did not. Rib fractures, lung contusions, and associated head, abdominal, and skeletal injuries are common because of the predominance of blunt-injury mechanisms. Nearly one half of chest injuries occurred without rib fractures. The need for ventilatory support is uncommon; when required, its duration is generally brief. Aortic transection, flail chest, and penetrating injuries more frequently encountered in adults and are uncommon in children. Thoracotomy generally is not required.(ABSTRACT TRUNCATED AT 400 WORDS)     

The financial burden of rib fractures: National estimates 2007 to 2016

BackgroundThe aim of this study is to define the cost of rib fracture hospitalization by single, multiple, and flail type using a nationally representative sample.MethodsThe national inpatient sample (NIS) was used to identify patients with a primary diagnosis of rib fracture hospitalization 2007-2016. International Classification of Diseases, Ninth Revision (ICD-9) and Tenth Revision (ICD-10) codes were used to characterize patients as having single, multiple, or flail chest rib fractures. Patients with only trauma related diagnosis groups (DRG) at the time discharge were included in the final sample. The cost of hospitalization was obtained by converting reported charges into cost using the all-payer inpatient cost-to-charge ratio (CCR) for all hospitals in the NIS data. The log of cost was modeled using multivariate linear regression. The rib fracture type was the primary predictor in the model.ResultsThere were 373,053 rib fracture admissions during 2007-2016. The average cost per hospitalization was $10,169 (95%Confidence Interval [CI]: 9,942–10,395), which translated into a national expenditure of $3.64 billion over 10 years. The cost of rib fracture hospitalization increased from $209 million in 2007 to $469 million in 2016. Compared to single rib fracture patients, the cost of hospitalization for multiple rib fractures and flail chest was 3% (p = 0.001) and 5% (p=0.02) higher, respectively. Higher injury severity score, total number of body regions injured and longer length of stay were associated with higher rib fracture hospitalization cost.ConclusionsRib fractures affect ~22,000-45,000 people per year in the United States. The cost of rib fractures is over $469 million per year and is increasing over time. Multiple rib fractures and flail chest rib fractures are associated with increased cost. Pathways to improve care in patients with rib fractures should consider the cost of treatment.     

Seltene Komplikation einer dislozierten Rippenfraktur: der ungewöhnliche klinische Verlauf nach einem Motorradsturz

Dislocated rib fractures as a result of traffic accidents can be associated with various injuries of thoracic and abdominal organs. Especial attention should be paid to rare and difficult to determine lesions of a hollow abdominal viscus, which can, if not diagnosed early enough, lead to septic shock with a considerably diminished probability of survival. The following case is of a 51-year-old man who suffered a blunt chest injury with dislocated rib fracture, which caused a gastric perforation that had not been primarily detected. The diagnostic approach with its challenges for treating physicians and alternatives to the standard procedure in the case of dislocated fractures of lower ribs is analyzed here.     

Review of 9 Cases of Diaphragmatic Injury Following Blunt Trauma Chest; 3 Years Experience

Diaphragmatic injuries can occur with both blunt and penetrating trauma which can be associated with herniation of abdominal viscera into the thoracic cavity. Diaphragmatic injuries can occur with blunt trauma chest in 1–7 % of patients. Retrospectively for last 3 years all cases blunt trauma chest admitted to surgery were reviewed and a study of cases of diaphragmatic rupture was done. We analysed 496 patients of blunt trauma chest retrospectively for period of three years. Nine patients have diaphragmatic injuries, all were males, six presented acutely three were chronic. In six patients laparotomy was done, four subcostal and two midline incisions were preferred. In chronic cases thoracotomy was done. Left sided injury predominates and rib fractures are most common associated finding. Diagnosis in majority of cases is made by Computerised tomography scan. Subcostal incision may be used in patients with isolated diaphragmatic injury in acute presentation while thoracotomy is preferred in late cases. Most common morbidity is pulmonary complications

Clinical outcomes of multiple rib fractures: does age matter?

Purpose

To evaluate the clinical outcomes of multiple rib fracture due to blunt trauma in young patients, a 3-year retrospective study was conducted. Patients with ≥3 rib fractures were divided into two groups (group I: <45 years old and group II: ≥45 years old). Mortality, hospital stay, ventilatory support, chest tubes insertion and associated injuries were studied.

Results

Of the 902 patients admitted with blunt chest trauma, 240 (27 %) met the inclusion criteria and 72.5 % patients were <45 years old. The most common causes of injury were motor vehicle crash (59 %) and fall (29 %). The Injury Severity Score (ISS) was higher in group I (16 ± 9 vs. 13 ± 6; p = 0.04). Hospital mortality was higher in group II (6 vs. 2 %; p = 0.18). Pneumothorax, haemothorax and ventilatory support were comparable. Patients in group II were more likely to undergo chest tubes insertion (26 vs. 14 %; p = 0.04), while group I had a significantly higher incidence of associated abdominal injuries (25 vs. 12 %; p = 0.03).

Conclusion

Old age presenting with rib fractures is associated with higher mortality in comparison to young age; however, this difference becomes statistically insignificant in the presence of multiple rib fracture.     

Rib fractures in blunt chest trauma: factors that influence daily patient controlled opiate use during acute care

BackgroundOpiates are frequently used in the inpatient management of chest wall injury following blunt trauma. However, the daily sum of opiates used during acute care, and the impact that additional injuries or rib fracture displacement may have on daily opiate requirement is unknown.MethodsA retrospective sample of 85 adult patients admitted to a tertiary trauma centre between April 2018 and October 2019 after a major chest wall injury (Abbreviated Injury Scale >2) and referral to Acute Pain Management Service was used in this study. Daily opiate usage was calculated each day for the first seven days following initial admission and converted to morphine milliequivalents (MME). Additional adjunct analgesia therapy was also recorded each day. The presence of rib fracture displacement and concurrent clavicle/scapular fractures was also noted. A comparison of the average daily MME for the various subgroups of interest was performed.ResultsThe maximum average MME in patients with rib fractures typically occurs at day 2 post injury and admission, with the highest day 2 average MME being in the Patient Controlled Analgesia (PCA) and ketamine subgroup. Presence of rib displacement delayed the onset of maximal MME to day 3 and resulted in higher average MME over the total seven days. Patients with concurrent clavicle or scapular fractures also had higher average MME each day, regardless of the addition of a regional block.ConclusionsThis study has demonstrated the daily opioid requirement is maximal on day 2 post-admission following isolated major chest wall injury. The addition of a regional block resulted in a reduction of the average MME used each day over the first seven days post-admission, compared to ketamine when added to PCA. The presence of displaced rib fractures or clavicle/scapular fractures increased the MME used each day, changed the day of peak consumption and increased the average daily opioid requirement during acute hospitalisation.
