This study aimed at prediction of long bone fractures and analysis of lower extremity injury mechanisms in real world passenger car to pedestrian collision. For this purpose, two cases of car to pedestrian accidents with detail recorded lower extremity injuries were reconstructed using Multi-body system (MBS) and Finite element (FE) models. The MBS models were used to determine lower extremity impact conditions, such as impact velocity, contact location as well as impact orientation. Furthermore, impact conditions were used to define initial boundary conditions in the simulation of lower extremity colliding with car front end using FE models. The bending moment and von Mises stress distributions of long bone were calculated in FE model to evaluate long bone fracture risks. Then, injury outcomes from simulations were compared with hospital recorded injury data. The simulation results of long bone fracture were consistent with the injury pattern and positions from hospital records. Moreover, the calculated fracture moments of tibia and fibula shaft as well as femur neck region were 310.8, 21.4 and 304.7 Nm, respectively. The FE model is capable to reproduce the dynamic injury process and is an effective tool to demonstrate the dynamic response of the injury and to predict the risk of long bone fractures.

This study demonstrates that long bone fracture treatment in food and fibre producing animals is in most cases successful. The greatest disadvantage of such treatment are the costs of the surgery and implants.

Abstract Background Long bone fractures are a frequent reason for visits to the pediatric emergency department (ED) where patients obtain the definitive care they require. Youth are rarely involved in quality assessment and improvement initiatives. Objectives To describe parent and youth experiences of their ED care for suspected long bone fractures. Design/Methods This prospective survey study of parents/youth consulting a tertiary care pediatric ED used surveys co-constructed by ED clinicians and parent partners. English/French speaking patients aged 10 to 18 years old with suspected long-bone fracture at triage – and their parents – were eligible to complete the survey during their ED stay. Electronic surveys were developed for parents and youth and pre-tested with 12 youth and 14 parents. Descriptive data was generated using SPSS v.25 (IBM Inc.). Results Three hundred surveys were distributed to eligible participants from March 2018 to June 2019 and 249 surveys were completed (148 parents, 101 youth). At least one member from 189 families completed a survey. Parents and youth participants had median ages of 44 and 12 years old, respectively. Most patients (98%) had a radiograph as part of their work-up, usually in the ED (76%); Twenty-seven percent were referred with radiographs. Most families (61%) received a diagnosis of long-bone fracture and were referred to orthopaedics for outpatient follow-up. Families’ median length of stay was 4h08min (range 43 min-14h30min). Parents (88mm) and youth (81mm) reported high median satisfaction with their overall ED care on 100 mm visual analog scales. Most parents (81%) and youth (75%) reported receiving just enough information from ED staff, though only half (50%) of the parents received information on how to care for their child at home. More than 90% of parents believed that the ED team treated their child’s pain. Eighty-one percent of youth reported that pain was treated sufficiently although 63% believed it had been treated quickly. Most parents (56%) and youth (72%) reported their ED stay was longer than anticipated; parents’ perceptions did not correlate with ED length of stay on logistic regression (p=0.014), while youth’s did (p=0.009). Few parents (33%) or youth (32%) reported receiving regular information on ED wait times. Conclusion Parent and youth perspectives of their ED care are complementary, and both should be considered in patient-oriented quality improvement initiatives.

Long bones are bones that include the humerus, radius, ulna, femur, tibia and fibula. Aside from fibula, the main function of long bones is as the main skeleton in movement. Therefore, whenever there is a fracture in the long bone, the ability to move will be lost.The occurrence of this long bone fracture itself is still a global problem because the number of events is still quite large. This is in line with the increase in socioeconomic status and the incidence of traffic accidents which is one of the causes of fractures. METHOD This study is a prospective study to determine the magnitude of the cost of treatment conservatively in cases of long bone fractures in RSUD dr. Soetomo. The study design used was a prospective cohort. The sample size used in this study was determined by consecutive sampling, ie patients who met the inclusion criteria in the period May - August 2017. RESULTS From the observations for four months from May 2017 - August 2017 at Emergency Room Soetomo General Hospital, found 77 patients with long bone fractures that were casted. Of these patients, 38 patients were placed in a slab, 39 patients were placed in a circular cast. Among the 39 people, 17 patients were excluded according to the exclusion criteria and 22 patients were included as the study sample according to the inclusion criteria. By using a statistical test using paired sample T test with a value of α = 0.05, a significance of 0.025 was obtained. Because the significance value is 0.025 <0.05 (α). DISCUSSION From the resultsa difference between the BPJS rate of installing circular cast on long bone fractures with the real cost of installing circular cast on long bone fractures. In addition, from the value of the mean we get that the average value of the BPJS rate is greater than the real cost value, which means we can conclude that the BPJS cost can cover the cost of conservative therapy in cases of long bone fractures. CONCLUSION In the economic aspect, the longer the length of stay means the higher the costs that must be paid by the patient (the payer) and accepted by the hospital. This only applies to real tariffs, whereas to INACBG's long or short length of stay does not affect the cost.
