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.

Background: Fracture of long bones is a common orthopaedic condition noticed in dogs and its primary goal is to completely restore the function of the injured limb as early as possible. Osteo-conductivity of hydroxyapatite can be improved further by decreasing the particle size to nanometre range and incorporation of inorganic materials in hydroxyapatite can enhance osteoblast cell material interactions. Strontium, Zinc, Silver and Fluorine are known to play an important role in the bone formation and also affect bone material characteristics such as crystallinity, degradation behaviour and mechanical properties. When doped with plasma spray nanohydroxyapatite, these multi-ions cause no harm to the physical environment during the degradation process of hydroxyapatite as these are nontoxic and play significant role in bone metabolism, growth and nourishment. Bone markers have tremendous potential as a rapid and sensitive method for assessing the response of the skeleton to medical or surgical interventions providing valuable information regarding bone turn over in animals. Hence, the current study was undertaken to evaluate the potential of multi-ion doped nano-hydroxyapatite coated intramedullary titanium implants in long bone fracture repair in dogs compared to the conventional intramedullary titanium implants through radiographical studies and evaluation of bone markers. Methods: Radiographical evaluation, Sandwich ELISA kits developed by Bioassay technology laboratory. Result: Plasma spray nano-hydroxyapatite coated titanium intramedullary implants have shown excellent osteo-conductivity when doped with multi-ions of Strontium, Zinc, Silver and Fluorine facilitating rapid osteoblastic activity and rapid bone turnover at the fracture site and complete fracture healing by 3rd week post-operatively as evidenced by radiographic scores and a peak BALP (Canine Bone Alkaline Phosphatase) values and early limb usage. Bone reabsorption and bone tissue remodelling due to osteoclastic action at the fracture site was quicker when the multi-ion doped nano-hydroxyapatite coated titanium intramedullary implants were used which is evidenced by the radiographic scores and highest CTX (Canine C-telopeptide of Type 1 Collagen) values indicating completion of fracture healing and near completion of bone tissue remodelling by 9th post-operative week in long bone fracture repair in dogs.

Abstract Background and Purpose There are few studies addressing the rate of application of bone allograft and its use; hence, the present study aimed to compare the clinical outcomes of using bone allograft and autograft in patients with long bone fracture. Method In this clinical trial study, all patients who underwent bone graft surgery with the diagnosed long bone fractures of upper and lower limbs at Shahid Beheshti Hospital were included in the research. Patients were divided into two groups, autograft and allograft, according to type of treatment. They were evaluated for their union, complications, and range of motion. Results In the present study, 124 people were studied. Among them, 100 patients were eligible and included in the study. The allograft and autograft groups did not have any statistical significant differences in terms of age, sex, location, causes of fracture, and surgical methods. Results of the present research on patients in terms of fracture site indicated that there was no significant relationship between the two groups in rate of union (P = 0.18). Allograft and autograft had no difference in terms of complications. Studied range of motion indicated that patients were not different in terms of their ranges of motion. Conclusion Based on findings of the present study, allograft could be a suitable substitute for the autograft. The two graft methods were similar in terms of complications, union, and ranges of motion.

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.

The reduction of long bone fractures is traditionally an invasive procedure with drawbacks of intense force, soft tissue damage, and, both, rotational and longitudinal malalignment. To combat these drawbacks, we applied a novel, wide open, three-legged, 6-DOF parallel robot, to the current surgical procedure. This platform will balance the accuracy, payload, and workspace for the surgeon, resulting in more efficient, successful surgeries. The experimental tests on a phantom reveal that the mechanism is well capable of applying the desired reduction steps against the large muscular payloads with high accuracy.

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.

Abstract Objective To measure the variability in discharge opioid prescription practices for children discharged from the emergency department (ED) with a long-bone fracture. Design A retrospective cohort study of pediatric ED visits in 2015. Setting Four pediatric EDs. Subjects Children aged four to 18 years with a long-bone fracture discharged from the ED. Methods A multisite registry of electronic health record data (PECARN Registry) was analyzed to determine the proportion of children receiving an opioid prescription on ED discharge. Multivariable logistic regression was performed to determine characteristics associated with receipt of an opioid prescription. Results There were 5,916 visits with long-bone fractures; 79% involved the upper extremity, and 27% required reduction. Overall, 15% of children were prescribed an opioid at discharge, with variation between the four EDs: A = 8.2% (95% confidence interval [CI] = 6.9–9.7%), B = 12.1% (95% CI = 10.5–14.0%), C = 16.9% (95% CI = 15.2–18.8%), D = 23.8% (95% CI = 21.7–26.1%). Oxycodone was the most frequently prescribed opioid. In the regression analysis, in addition to variation by ED site of care, age 12–18 years, white non-Hispanic, private insurance status, reduced fracture, and severe pain documented during the ED visit were associated with increased opioid prescribing. Conclusions For children with a long-bone fracture, discharge opioid prescription varied widely by ED site of care. In addition, black patients, Hispanic patients, and patients with government insurance were less likely to be prescribed opioids. This variability in opioid prescribing was not accounted for by patient- or injury-related factors that are associated with increased pain. Therefore, opioid prescribing may be modifiable, but evidence to support improved outcomes with specific treatment regimens is lacking.
