"Do You Need a Doctor's Note?" Factors Leading to Delayed Return to Work after Blunt Chest Trauma.

BACKGROUND: Blunt chest trauma is associated with significant morbidity, but the long-term functional status for these patients is less well-known. Return to work (RTW) is a benchmark for functional recovery in trauma patients, but minimal data exist regarding RTW following blunt chest trauma. MATERIALS AND METHODS: Patients ≥ 18 y old admitted to a Level 1 trauma center following blunt chest trauma with ≥ 3 rib fractures and length of stay (LOS) ≥ 3 d were included. An electronic survey assessing RTW was administered to patients after discharge. Patients were stratified as having delayed RTW (> 3 mo after discharge) or self-reported worse activities-of-daily-living (ADL) function after injury. Patient demographics, outcomes, and injury characteristics were compared between groups. RESULTS: Median time to RTW was 3 mo (IQR 2,5). Patients with delayed RTW had higher odds of having more rib fractures than those with RTW ≤ 3 mo (median 10 versus 7; OR:1.24, 95%CI:1.04,1.48) as well as a longer LOS (median 13 versus 7 d; OR:1.15, 95% CI:1.04,1.30). Patients with stable ADL after trauma returned to work earlier than those reporting worse ADL (median 2 versus 3.5 mo, P < 0.01). 23.6% of respondents took longer than 5 mo to return to independent functioning, and 50% of respondents' report limitations in daily activities due to physical health after discharge. CONCLUSIONS: The significant proportion of patients with poor physical health and functional status suggests ongoing burden of injury after discharge. Patients with longer LOS and greater number of rib fractures may be at highest risk for delayed RTW after injury.

Early risk stratification of in hospital mortality following a ground level fall in geriatric patients with normal physiological parameters.

BACKGROUND: The purpose of this study was to identify risk factors of mortality for geriatric patients who fell from ground level at home and had a normal physiological examination at the scene. METHODS: Patients aged 65 and above, who sustained a ground level fall (GLF) with normal scene Glasgow Coma Scale (GCS) score 15, systolic blood pressure (SBP) > 90 and <160 mmHg, heart rate ≥ 60 and ≤100 beats per minute) from the 2012-2014 National Trauma Data Bank (NTDB) data sets were included in the study. Patients' characteristics, existing comorbidities [history of smoking, chronic kidney disease (CKD), cerebrovascular accident (CVA), diabetes mellitus (DM), and hypertension (HTN) requiring medication], injury severity scores (ISS), American College of Surgeons' (ACS) trauma center designation level, and outcomes were examined for each case. Risks factors of mortality were identified using bivariate analysis and logistic regression modeling. RESULTS: A total of 40,800 patients satisfied the study inclusion criteria. The findings of the logistic regression model for mortality using the covariates age, sex, race, SBP, ISS, ACS trauma level, smoking status, CKD, CVA, DM, and HTN were associated with a higher risk of mortality (p < .05). The fitted model had an Area under the Curve (AUC) measure of 0.75. CONCLUSION: Cases of geriatric patients who look normal after a fall from ground level at home can still be associated with higher risk of in-hospital death, particularly those who are older, male, have certain comorbidities. These higher-risk patients should be triaged to the hospital with proper evaluation and management.

[Innovated Judet Ribs Plates - Preclinical Study, First Clinical Experience]. / Inovované zeberní dlahy Judetova typu ­ preklinická studie, první klinické zkusenosti.

PURPOSE OF THE STUDY Based on the experience with using the Judet plates in stabilization of rib fractures an innovated Judet plate was constructed in cooperation with the Development Department of Medin company. During the preclinical part of the project, following the construction of the new Judet plate, a surgical technique was elaborated. Subsequently, the clinical application of rib osteosynthesis with innovated plates was commenced. MATERIAL AND METHODS In the course of the last three years the innovated Judet rib plate including the instruments were constructed by the Development Department of Medin company in cooperation with the Trauma Centre and the Department of Surgery of the University Hospital Královské Vinohrady. The goal of the innovation was the changes in technical parameters of rib plates which are compared with the new plates of other companies: 1. Adequate plate stability along the rib axis. 2. Creation of fixation clips for a stable, but not traumatized fixation of the plate around the rib. 3. Decreased robustness of the plate with sufficient stiffness. 4. Working out of a new technique of plate fixation with the use of new instruments. 5. Ensuring plate fixation with cortical locking screws. In the preclinical part of the project osteosynthesis of the broken rib was performed with a plate on a chest model for the basic types of rib fractures. Subsequently, the plate was used for rib osteosynthesis in a cadaver. The goal of the new instruments was besides temporarily maintaining the rib fracture reduction also the subsequent temporary application of plates with the assistance of fixation tongs before the final fixation of plates. In 2017, the clinical part of the project on the stabilisation of flail chest with the innovative Judet plates was launched. This type of innovative Judet plates has so far been used in 3 patients. RESULTS As to the surgical technique of ribs osteosynthesis: The profile of the plate has been adapted to the rib profile and can be further adjusted to rib curvature, also the fixation shoulders of the plates have been reshaped. The innovated plate has been complemented with a new configuration of fixation clips and the possibility to fix the plate with locking screws. The used cortical locking screws enable appropriate stabilisation of plates. They were tested on a laboratory model of ribs and on a cadaver using the new set of instruments. The plates can be easily shaped with tongs. The anchorage of fixation clips is adequately provided for also by means of tongs. The plates can be fixed to the rib without any significant compression of intercostal nerves. The essential change of the innovated Judet plate is its weight, which meets the contemporary trends in construction of rib plates designed for anatomical fixation. The first experience with the innovated plates in flail chest injury confirmed the safety of the procedure for stable osteosynthesis of rib fractures. Adequate stability of the chest wall facilitated an early withdrawal of ventilatory support. Osteosynthesis of rib fractures with innovated plates performed in the first three patient was without complications, including in the postoperative period. DISCUSSION A series of prospective studies prove the correctness of the indications of early rib osteosynthesis in flail chest. Further indications for rib osteosynthesis are postinjury chest deformity, dislocation of rib fracture fragments with a lung injury, and malunion of rib fracture. According to these studies the surgical stabilisation of the chest is a safe and efficient method resulting in pain reduction, decrease of ventilatory support time, and also in reduced morbidity. For rib osteosynthesis anatomical plates, Judet plates and intramedullary plates are used. Our innovation of the Judet plate aimed to improve the technical parameters of the plate. The innovative Judet plate means a significant improvement in technical parameters and stands comparison with the plates of others companies, which are used in the Czech Republic. This is also evidenced by preliminary clinical results. CONCLUSIONS Surgical stabilisation of the flail chest segment is considered to be he method of choice in treating selected patients, leading to the improvement of respiratory function and shortening of the ventilatory support time. The new technical parameters of the plate, including its weight, new fixation clips, locking screws and instruments are the priorities of the innovated Judet plates. The innovation of Judet plates represents an important step towards the extension of indications for surgical stabilisation of the chest. Key words:innovative Judet plates, preclinical study, osteosynthesis of rib fractures.

When Should Abdominal Computed Tomography Be Considered in Patients with Lower Rib Fractures?

BACKGROUND: Lower rib fractures are considered as a marker of intra-abdominal organ injury. Abdominal computed tomography (CT) is the "gold standard" examination for patients with lower rib fractures. However, the reported incidence of concomitant intra-abdominal injuries (IAI) is 20%-40%. OBJECTIVE: The purpose of this study was to evaluate the incidence of intra-abdominal organ injuries in blunt trauma patients with lower rib fractures. METHODS: Medical charts and radiology reports of patients with lower rib (from the 8th to 12th rib) fractures admitted to our center during a 6-year period were retrospectively reviewed. Patients were divided into two groups. Group I included patients with intra-abdominal injury (IAI) diagnosed either by CT or on urgent laparotomy, and Group II included those with normal abdominal CT scans. Data included demographics, mechanism of injury, laboratory tests, radiology results including number and location of fractured ribs, and incidence of IAI. RESULTS: Overall 318 patients were included in the study. Fifty-seven patients (17.9%) had 71 IAIs compared with 265 (82.1%) patients with no IAI. Logistic regression identified age younger than 55 years (relative risk [RR] = 7.2; 95% confidence interval [CI] 3.1-16.8; p = 0.001), bilateral rib fractures (RR = 3.9; 95% CI 1.1-13.5; p = 0.03) and decreased levels of hematocrit (RR = 2.4; 95% CI 1.2-4.8; p = 0.016) as independent risk factors for the presence of IAI. CONCLUSIONS: Abdominal CT should be considered in blunt trauma patients with lower rib fractures who are younger than 55 years of age and have bilateral rib fractures and decreased levels of hematocrit on admission.

Functional Impact of a Minor Thoracic Injury: An Investigation of Age, Delayed Hemothorax, and Rib Fracture Effects.

OBJECTIVE: To investigate whether minor thoracic injuries (MTIs) relate to subsequent functional limitations. BACKGROUND: Approximately 75% of patients with an MTI are discharged after an emergency department (ED) visit, whereas significant functional limitations can occur in the weeks that follow. METHODS: A 19 months' prospective cohort study with a 90-day follow-up was conducted at 4 university-affiliated EDs. Patients 16 years and older with an MTI were assessed at initial ED visit, 7, 14, 30, and 90 days after injury. Functional outcome was measured using the SF-12 scale. General linear model were used to assess outcome. RESULTS: A total of 482 patients were included, of whom 127 (26.3%) were 65 or older. Overall, 147 patients (30.5%) presented with at least 1 rib fracture and 59 subjects (12.2%) with delayed hemothorax. At 90 days, 22.8% of patients still had severe or moderate disabilities on global physical health score. Patients with solely delayed hemothorax and no rib fracture had the lowest global physical health score (46.4 vs 61.1, P < 0.01, effect size =  -2.60) than patients with simple MTI. Generally, functional limitations also increase with increments of number of rib fracture detected on radiograph. Outcomes were not different among patients 65 years or older when compared to their younger counterparts. CONCLUSIONS: In this prospective study of MTIs, severe to moderate disabilities were present in nearly 1 patient out of 5 at 90 days. The presence of delayed hemothorax and the number of rib fracture were associated with increased functional limitations after a MTI.

Minimal-trauma fracture in women with breast cancer surviving for at least 5 years from diagnosis.

SUMMARY: Minimal-trauma fracture is an important issue in breast cancer survivors, especially rib fracture. The likelihood of fracture is affected by menopausal status and a diagnosis of osteoporosis prior to breast cancer. Most women reported at least one assessment of bone mineral density. INTRODUCTION: We have investigated the self-reported frequency and pattern of minimal-trauma fracture (MTF) in breast cancer (BC) survivors at least 5 years from diagnosis, along with the use of bone mineral density (BMD) assessment. METHODS: This study was carried out within the Bupa Health Foundation Health and Wellbeing After Breast Cancer Study which is a questionnaire-based prospective cohort study of 1683 women diagnosed with their first invasive breast cancer between 2004 and 2006 and followed for at least 5 years. RESULTS: One thousand two hundred and five women, who remained free of recurrence or new breast cancer, completed the fifth annual follow-up. One hundred sixty-four (13.6%) reported at least one MTF. Rib fracture was the most common (52 fractures in 46 women). Compared with women who remained pre-/peri-menopausal, either being postmenopausal at diagnosis (OR 3.53, 95% Confidence Interval (CI) 1.09-11.44, p=0.036) or changing from pre- to postmenopausal during follow-up (OR 3.97, 95% CI 1.21-13.10, p=0.023) was associated with a higher likelihood of fracture, as was having a diagnosis of osteoporosis at the time of diagnosis (OR 1.74, 95% CI 1.00-2.99, p=0.047). Most women (64.9%) reported at least one BMD assessment. CONCLUSIONS: Overall MTF is a problem for breast cancer survivors, with rib fracture a particular issue for women in our study. Both pre-existing osteoporosis and being postmenopausal are risk factors for subsequent MTF in women treated for breast cancer. Clinicians need to be mindful of fracture prevention medication in these groups.

Together is better - RibScore and SCARF in the prediction of pulmonary complications and association with SSRF.

BACKGROUND: Optimal treatment of patients with rib fractures requires identification of those patients at risk of pulmonary complications. It is also important to determine which patients would benefit from Surgical Stabilisation of Rib Fractures (SSRF). This study aims to validate two scoring systems (RibScore and SCARF score) in predicting complications and association with SSRF in an Australian trauma population. Clinical observation suggests that complications and criteria for SSRF is associated with anatomical and physiological factors. Therefore it is hypothesized that utilisation of an anatomical (RibScore) and physiological (SCARF) in conjunction will have improved predictive ability. METHOD: Retrospective cohort study of rib fracture patients admitted to an Australian Level I trauma centre from Jan 2017 to Jan 2021. RibScore and SCARF score were calculated. Multivariate logistic regression was performed to determine risk factors associated with complications and SSRF, as well the scoring systems' ability via ROC AUC. RESULTS: 1157 patients were included. Higher median RibScore (1vs0; p < 0.001) and SCARF score (3vs1, p < 0.001) was associated with development of complications. Similarly for SSRF, RibScore (3vs0; p < 0.001), SCARF score (3vs1; p < 0.001) were higher. On multivariate analysis, increasing RibScore and SCARF score were associated with an increased risk of respiratory failure, pneumonia, death, and SSRF. The sensitivity for a patient with a high risk score in either RibScore or SCARF increased to 96.3 % in identifying pulmonary complications (from 66.7 % in RibScore and 88 % in SCARF, when used individually) and 91.9 % in identifying association with SSRF (from 86.5 % in RibScore and 70.3 % in SCARF). CONCLUSION: RibScore and SCARF score demonstrate predictive ability for complications and SSRF in an Australian trauma rib fracture population. Combining a radiological score with a clinical scoring system demonstrates improved sensitivity over each score individually for identifying patients at risk of complications from rib fractures, those who may require SSRF, and those who are low risk. STUDY TYPE: Retrospective Cohort Study LEVEL OF EVIDENCE: Level III.

Favourable outcome in survivors of CPR-related chest wall injuries.

BACKGROUND: There is a lack of studies focusing on long-term chest function after chest wall injury due to cardiopulmonary resuscitation (CPR). The purpose of this cross-sectional study was to investigate long-term pain, lung function, physical function, and fracture healing after manual or mechanical CPR and in patients with and without flail chest. METHODS: Patients experiencing out-of-hospital cardiac arrest between 2013 and 2020 and transported to Sahlgrenska University Hospital were identified. Survivors who had undergone a computed tomography (CT) showing chest wall injury were contacted. Thirty-five patients answered a questionnaire regarding pain, physical function, and quality of life and 25 also attended a clinical examination to measure the respiratory and physical functions 3.9 (SD 1.7, min 2-max 8) years after the CPR. In addition, 22 patients underwent an additional CT scan to evaluate fracture healing. RESULTS: The initial CT showed bilateral rib fractures in all but one patient and sternum fracture in 69 %. At the time of the follow-up none of the patients had persistent pain, however, two patients were experiencing local discomfort in the chest wall. Lung function and thoracic expansion were significantly lower compared to reference values (FVC 14 %, FEV1 18 %, PEF 10 % and thoracic expansion 63 %) (p < 0.05). Three of the patients had remaining unhealed injuries. Patients who had received mechanical CPR in additional to manual CPR had a lower peak expiratory flow (80 vs 98 % of predicted values) (p=0.030) =0.030) and those having flail chest had less range of motion in the thoracic spine (84 vs 127 % of predicted) (p = 0.019) otherwise the results were similar between the groups. CONCLUSION: None of the survivors had long-term pain after CPR-related chest wall injuries. Despite decreased lower lung function and thoracic expansion, most patients had no limitations in physical mobility. Only minor differences were seen after manual vs. mechanical CPR or with and without flail chest.

Assessment and management of rib fracture pain in geriatric population: an ode to old age.

PURPOSE OF REVIEW: Pain management for traumatic rib fractures has been described in literature, but there is paucity of data when it comes to acute pain management in the elderly, let alone pain resulting from traumatic rib fractures. RECENT FINDINGS: This article focuses on challenges of assessment of pain in elderly patients and the various options available for pain management including utilization of nerve blocks. Nerve blocks are instrumental in treating rib fracture pain along with utilization of opioids and nonopioids thus formulating a multimodal approach to pain management. SUMMARY: The goal is to devise a proper pain management regimen for geriatric patients with rib fractures to decrease the morbidity and mortality associated with it. Developing institutional protocols is one step forward towards quality care for such patients.

Transient expression of myofibroblast-like cells in rat rib fracture callus.

BACKGROUND AND PURPOSE: We have previously shown that early fracture callus of rat rib has viscoelastic and contractile properties resembling those of smooth muscle. The cells responsible for this contractility have been hypothesized to be myofibroblast-like in nature. In soft-tissue healing, force generated by contraction of myofibroblasts promotes healing. Accordingly, we tried to identify myofibroblast-like cells in early fibrous callus. ANIMALS AND METHODS: Calluses from rat rib fractures were removed 7, 14, and 21 days after fracture and unfractured ribs acted as controls. All tissues were analyzed using qPCR and immunohistochemistry. We analyzed expression of smooth muscle- and myofibroblast-associated genes and proteins including alpha smooth muscle actin (αSMA), non-muscle myosin, fibronectin extra domain A variant (EDA-fibronectin), OB-cadherin, connexin-43, basic calponin (h1CaP), and h-caldesmon. RESULTS: In calluses at 7 days post-fracture, there were statistically significant increases in expression of αSMA mRNA (2.5 fold), h1CaP mRNA (2.1 fold), EDA-fibronectin mRNA (14 fold), and connexin-43 mRNA (1.8 fold) compared to unfractured ribs, and by 21 days post-fracture mRNA expression in calluses had decreased to levels approaching those in unfractured rib. Immunohistochemistry of 7 day fibrous callus localized calponin, EDA-fibronectin and co-immunolabeling of OB-cadherin and αSMA (thus confirming a myofibroblastic phenotype) within various cell populations. INTERPRETATION: This study provides further evidence that early rat rib callus is not only smooth muscle-like in nature but also contains a notable population of cells that have a distinct myofibroblastic phenotype. The presence of these cells indicates that in vivo contraction of early callus is a mechanism that may occur in fractures so as to facilitate healing, as it does in soft tissue wound repair.

[MSCT optimal examination time for unconspicuous rib fracture].

OBJECTIVE: To explore MSCT optimal examination time for patients with unconspicuous rib fracture. METHODS: Sixty-three patients with thoracic trauma from January 2009 to June 2011 were collected. They were examined by MSCT in the first week after trauma and re-examined during eighth weeks after trauma. The number of rib which had been found fractured in the first examination was compared to that in re-examinations. RESULTS: Patients with fine rib fracture often have different diagnostic results at different examination time after trauma. There was statistical difference between the number in the first week and the third week to the fifth week. CONCLUSION: MSCT could show the pathophysiological changes of rib fracture objectively in the stage between the third week and the fifth week after trauma, which is optimal examination time for the fine rib fracture.

Patients with rib fractures: use of incentive spirometry volumes to guide care.

Rib fractures pose significant risk to trauma patients. Effective pain control and the ability to take deep breaths are crucial for optimal recovery, and these are key elements in current clinical guidelines. These guidelines use incentive spirometry volumes along with other assessment values to guide patient care. However, despite current guidelines, nurses do not routinely document inspired respiratory volumes. This article provides trauma nurses with the rationale for documenting and tracking incentive spirometry volumes to improve outcomes for patients with rib fractures. This promotes early detection of respiratory decline and early interventions to improve pain control and pulmonary function.

Outcomes of nonoperatively treated displaced scapular body fractures.

BACKGROUND: Displaced scapular body fractures most commonly are treated conservatively. However there is conflicting evidence in the literature regarding the outcomes owing to retrospective design of studies, different classification systems, and diverse outcome tools. QUESTIONS/PURPOSES: The functional outcome after nonoperative management of displaced scapular body fractures was assessed by change in the DASH (Disability of Arm, Shoulder and Hand) score; (2) the radiographic outcome was assessed by the change of the glenopolar angle (GPA); and (3) associated scapular and extrascapular injuries that may affect outcome were identified. PATIENTS AND METHODS: Forty-nine consecutive patients were treated with early passive and active ROM exercises for a displaced scapular body fracture. We followed 32 of these patients (65.3%) for a minimum of 6 months (mean, 15 months; range, 6-33 months). Mean age of the patients was 46.9 years (range, 21-84 years) and the mean Injury Severity Score (ISS) was 21.5 (range, 5-50). Subjective functional results (DASH score) and radiographic assessment (fracture union, glenopolar angle) were measured. RESULTS: All fractures healed uneventfully. The mean change of glenopolar angle was 9° (range, 0°-20°). The mean change of the DASH score was 10.2, which is a change with minimal clinical importance. There was a correlation between the change in this score with the ISS and presence of rib fractures. CONCLUSIONS: Satisfactory outcomes are reported with nonoperative treatment of displaced scapular body fractures. We have shown that the severity of ISS and the presence of rib fractures adversely affect the clinical outcome.

Rib fracture timing in dynamic belt tests with human cadavers.

The purpose of this article is to present data from dynamic belt loading tests on the thorax of human cadavers where the exact timing of all rib fractures is known. To quantify rib fracture timing, a total of 47 strain gages were placed throughout the thorax of two human cadavers (one male, one female). To simulate thoracic loading observed in a severe car crash, a custom table-top belt loading device was developed. The belt loading pulse was configured to result in approximately 40% chest compression during a 150 ms load and unload cycle. The time histories of each strain gage were analyzed to determine the time of each rib fracture which was then directly compared with the reaction loads and chest displacements at that exact time, thereby creating a noncensored data set. In both cadavers, all rib fractures occurred within the first 35% compression of the thorax. As a general trend, fractures on the left side of the thorax, where the passenger belt passed over the abdomen, occurred first followed by fractures to the upper ribs on the right side of the thorax. By utilizing this technique, the exact timing of each injury level can be characterized relative to the mechanical parameters. For example, using rib fractures as the parameter for Abbreviated Injury Scale (AIS) scores in the female test, it was shown that AIS 1 injury occurred at a chest compression of 21.1%, AIS 2 at 21.6%, AIS 3 at 22.0%, and AIS 4 at 33.3%.

Preliminary study of the characteristics of rib fractures and their impact on pulmonary ventilatory function.

BACKGROUND: This study aimed to investigate the pulmonary ventilation function (PVF) according to different types of rib fractures and pain levels. METHODS: This was a retrospective study of patients with thoracic trauma admitted to our ward from May 1, 2015, to February 1, 2017. Vital capacity (VC), forced expiratory volume in 1 s (FEV1), and peak expiratory flow (PEF) were measured on admission. A numerical rating scale (NRS) was used for pain assessment. RESULTS: A total of 118 (85 males and 33 females) were included. The location of rib fractures did not affect the PVF. When the number of rib fractures was ≥5, the PVF was lower than in those with ≤4 fractures (VC: 0.40 vs. 0.47, P = 0.009; FEV1: 0.37 vs. 0.44, P = 0.012; PEF: 0.17 vs. 0.20, P = 0.031). There were no difference in PVF values between rib fractures with multiple locations and those with non-multiple locations (VC: 0.41 vs. 0.43, P = 0.202; FEV1: 0.37 vs. 0.39, P = 0.692; PEF: 0.18 vs. 0.18, P = 0.684). When there were ≥ 5 breakpoints, the PVF parameters were lower than those with ≤4 breakpoints (VC: 0.40 vs. 0.50, P = 0.030; FEV1: 0.37 vs. 0.45, P = 0.022; PEF: 0.18 vs. 0.20, P = 0.013). When the NRS ≥ 7, the PVF values were lower than for those with NRS ≤ 6 (VC: 0.41 vs. 0.50, P = 0.003; FEV1: 0.37 vs. 0.47, P = 0.040; PEF: 0.18 vs. 0.20, P = 0.027). CONCLUSIONS: When the total number of fractured ribs is ≥5, there are ≥5 breakpoints, or NRS is ≥7, the VC, FEV1, and PEF are more affected. TRIAL REGISTRATION: The trial was conducted in accordance with the Declaration of Helsinki (as revised in 2013). The study was approved by the Ethics Committee of Shanghai Jiao Tong University Affiliated Sixth People's Hospital, and individual consent for this retrospectively registered analysis was waived.

Acupuncture combined with multidisciplinary care for recovery after traumatic multiple rib fractures: a prospective feasibility cohort study.

INTRODUCTION: Acute pain significantly delays early physiological recovery and results in chronic functional disability in patients with traumatic multiple rib fractures (MRFs). This prospective cohort study aimed to investigate the feasibility of acupuncture combined with multidisciplinary care during recovery in patients with traumatic MRFs. METHODS: Twenty patients with traumatic MRFs who were admitted to a regional trauma centre in South Korea were enrolled. A combination of acupuncture and multidisciplinary inpatient ward management was provided at the trauma ward. Patients were permitted to continue acupuncture treatments at outpatient clinics for 3 months after the traumatic events. Clinical outcomes, including pain, acute physiological recovery, quality of life, patient satisfaction with the care provided, respiratory function and use of opioids, were evaluated up to 6 months after trauma. RESULTS: Seventeen (85%) participants completed the 6-month follow-up. One patient withdrew consent during admission due to discomfort after three sessions of acupuncture. The proportion of patients with above-moderate level of pain decreased from 95% at baseline to 41% at 6 months. Quality of life appeared to deteriorate consistently throughout the study period. Around 80% of respondents expressed satisfaction with the acupuncture treatments and stated that they found acupuncture to be acceptable. Over 94% of respondents reported slight or considerable improvement. CONCLUSION: The provision of acupuncture combined with multidisciplinary care for recovery in patients with traumatic MRFs was feasible in a regional trauma centre in South Korea. Randomised trials are needed to investigate the role of acupuncture combined with multidisciplinary care in the future. TRIAL REGISTRATION NUMBER: KCT0002911 (Clinical Research Information Service).

A clinical practice guideline using percentage of predicted forced vital capacity improves resource allocation for rib fracture patients.

BACKGROUND: Predicting rib fracture patients that will require higher-level care is a challenge during patient triage. Percentage of predicted forced vital capacity (FVC%) incorporates patient-specific factors to customize the measurements to each patient. A single institution transitioned from a clinical practice guideline (CPG) using absolute forced vital capacity (FVC) to one using FVC% to improve triage of rib fracture patients. This study compares the outcomes of patients before and after the CPG change. METHODS: A review of rib fracture patients was performed over a 3-year retrospective period (RETRO) and 1-year prospective period (PRO). RETRO patients were triaged by absolute FVC. Percentage of predicted FVC was used to triage PRO patients. Demographics, mechanism, Injury Severity Score, chest Abbreviated Injury Scale score, number of rib fractures, tube thoracostomy, intubation, admission to intensive care unit (ICU), transfer to ICU, hospital length of stay (LOS), ICU LOS, and mortality data were compared. A multivariable model was constructed to perform adjusted analysis for LOS. RESULTS: There were 588 patients eligible for the study, with 269 RETRO and 319 PRO patients. No significant differences in age, gender, or injury details were identified. Fewer tube thoracostomy were performed in PRO patients. Rates of intubation, admission to ICU, and mortality were similar. The PRO cohort had fewer ICU transfers and shorter LOS and ICU LOS. Multivariable logistic regression identified a 78% reduction in odds of ICU transfer among PRO patients. Adjusted analysis with multiple linear regression showed LOS was decreased 1.28 days by being a PRO patient in the study (B = -1.44; p < 0.001) with R2 = 0.198. CONCLUSION: Percentage of predicted FVC better stratified rib fracture patients leading to a decrease in transfers to the ICU, ICU LOS, and hospital LOS. By incorporating patient-specific factors into the triage decision, the new CPG optimized triage and decreased resource utilization over the study period.

Mapping of common rib fracture patterns and the subscapular flail chest associated with operative scapula fractures.

BACKGROUND: Rib fractures occur in approximately 10% of trauma patients and are associated with more than 50% of patients with scapula fractures. This study investigates the location and patterns of rib fractures and flail chest occurring in patients with operatively treated scapula fractures. Novel frequency mapping techniques of rib fracture patterns in patients who also injure the closely associated scapula can yield insight into surgical approaches and fixation strategies for complex, multiple injuries patients. We hypothesize that rib fractures have locations of common occurrence when presenting with concomitant scapula fracture that requires operative treatment. METHODS: Patients with one or more rib fractures and a chest computed tomography scan between 2004 and 2018 were identified from a registry of patients having operatively treated scapula fractures. Unfurled rib images were created using Syngo-CT Bone Reading software (Siemens Inc., Munich, Germany). Rib fracture and flail segment locations were marked and measured for standardized placement on a two-dimensional chest wall template. Location and frequency were then used to create a gradient heat map. RESULTS: A total of 1,062 fractures on 686 ribs were identified in 86 operatively treated scapula fracture patients. The mean ± SD number of ribs fractured per patient was 8.0 ± 4.1 and included a mean ± SD of 12.3 ± 7.2 total fractures. Rib fractures ipsilateral to the scapula fracture occurred in 96.5% of patients. The most common fracture and flail segment location was ipsilateral and subscapular; 51.4% of rib fractures and 95.7% of flail segments involved ribs 3 to 6. CONCLUSION: Patients indicated for operative treatment of scapula fractures have a substantial number of rib fractures that tend to most commonly occur posteriorly on the rib cage. There is a pattern of subscapular rib fractures and flail chest adjacent to the thick bony borders of the scapula. This study enables clinicians to better evaluate and diagnose scapular fracture patients with concomitant rib fractures. LEVEL OF EVIDENCE: Diagnostic test, level IV.

Pediatric surgical rib fixation: A collected case series of a rare entity.

BACKGROUND: Rib fractures are uncommon in children and are markers of extreme traumatic force from high-energy or nonaccidental etiology. Traditional care includes nonoperative management, with analgesia, ventilator support, and pulmonary physiotherapy. Surgical stabilization of rib fractures (SSRFs) has been associated with improved outcomes in adults. In children, SSRF is performed and its role remains unclear, with data only available from case reports. We created a collected case series of published pediatric SSRF cases, with the aim to provide a descriptive summary of the existing data. METHODS: Published cases of SSRF following thoracic trauma in patients younger than 18 years were identified. Collected data included demographics, injury mechanism, associated injuries, surgical indication(s), surgical technique, time to extubation, postoperative hospital stay, and postoperative follow-up. RESULTS: Six cases were identified. All were boys, with age range 6 to 16 years. Injury mechanism was high-energy blunt force in all cases, and all patients suffered multiple associated injuries. Five of six cases were related to motor vehicles, and one was horse-related. Indication(s) for surgery included ventilator dependence in five, significant chest deformity in two, and poor pain control in one case. Plating systems were used for rib stabilization in five of six cases, while intramedullary splint was used in one. All patients were extubated within 7 days following SSRF, and all were discharged by postoperative Day 20. On postoperative follow-up, no SSRF-related major issues were reported. One patient underwent hardware removal at 2 months. CONCLUSION: Surgical stabilization of rib fractures in children is safe and feasible, and should be considered as an alternative to nonoperative therapy in select pediatric thoracic trauma cases. Potential indications for SSRF in pediatric patients include poor pain control, chest wall deformity, or ventilator dependence. Further studies are needed to establish the role and possible benefits of SSRF in pediatric thoracic trauma. LEVEL OF EVIDENCE: Collected case series, level V.
