RESUMO

Introduction: Ipsilateral proximal and shaft femoral fractures typically occur in young adults after high-energy trauma. No consensus exists regarding the optimal internal fixation device or surgical strategy for these complex fractures. Our main objective is to identify differences on outcomes and complications between patients treated with one or combined implants. Material and method: This is a single-center retrospective cohort study in patients with associated fractures of the proximal (31 AO) and shaft femur (32 AO). We divided the patients into two groups according to the use of single (Group I) or combined implants (Group II). Demographic, clinical, radiological, surgical data and development of complications were collected.Results: We identified 28 patients (19 men and 9 women) with an average age of 43 years. We used an anterograde femoral nail in group I (17 patients) and a retrograde femoral nail or a plate associated with hip lag screws or sliding hip screw in Group II (11 patients). Patients were followed up for 26.28 (9.12–62.88) months. Osteonecrosis of the femoral head, osteoarthritis, infection or nonunion was found in 9 patients (32%). No significant differences (p 0.70) were found in complications between two groups or between definitive surgical fixation before or after the first 24h. Conclusions: No differences in the development of complications or timing of definitive fixation were found between the use of one or combined implants in ipsilateral proximal femur and shaft fractures. Regardless of the implant chosen, an appropriate osteosynthesis technique is crucial, even so high complication rates are expected.

Utilizamos un clavo femoral anterógrado en el grupo i (17 pacientes) y un clavo femoral retrógrado o una placa con tornillos a compresión o tornillo deslizante de cadera en el grupo ii (11 pacientes). Los pacientes fueron seguidos durante 26,28 (9,12-62,88) meses. Se encontró osteonecrosis de la cabeza femoral, osteoartritis, infección o seudoartrosis en 9 pacientes (32%). No se encontraron diferencias significativas (p=0,70) en las complicaciones entre los 2 grupos o entre la fijación quirúrgica definitiva antes o después de las primeras 24h. Conclusiones: No se encontraron diferencias en el desarrollo de complicaciones o el momento de la fijación definitiva entre el uso de un implante o combinado en fracturas ipsilaterales de fémur proximal y diafisario. Independientemente del implante elegido, una técnica de osteosíntesis adecuada es crucial; aun así son esperables altas tasas de complicaciones.(AU)

RESUMO

OBJECTIVE: Fractures remain a huge burden and their management adversely affects individuals' function and productivity during the lengthy healing period. Gut microbiota exerts a systemic influence on diverse aspects of host physiology, including bone. The primary objective of this study was to evaluate if oral probiotic treatment before or after a fracture in a mouse model could increase cytokines and biomarkers essential for bone healing with subsequent improvement in the biomechanical properties of the healed callus. METHODS: Femoral osteotomy and intramedullary pinning were performed on C57BL/6 mice. Group 1 received either control PBS or probiotic via oral gavage for 5 weeks before fracture (pre-fracture). Group 2 received equivalent treatments for 4 weeks only after fracture (post-fracture). Fracture calluses were harvested on day 3 and 7 for RT-qPCR to quantify osteogenic-related inflammatory cytokines and bone biomarkers. Fractured femurs were evaluated day 28 post-osteotomy via microstructural analysis (µCT) and biomechanical testing (torsion). RESULTS: Mice treated with probiotics pre-fracture (group 1) showed significantly increased gene expression on day 3 of cytokines TGF-ß, IL-6 and IL-17F and a corresponding increase in gene expression on day 7 for Col1 and Runx2. Significant improvement was also seen in bone volume fraction, bone mineral density, tissue mineral density, maximum yield torque, stiffness and strain energy. Mice treated with probiotics post-fracture (group 2), demonstrated no changes in cytokine or bone marker gene expression with no significant changes on microstructural analysis. However, significant increases were seen in twist angle at failure and strain energy, with a corresponding reduction in torsional stiffness. CONCLUSION: Our results suggest that oral probiotic administration, before or after a fracture, may sufficiently alter the gut flora microenvironment leading to improved bone healing biomechanical properties. The use of probiotics may provide a cost-effective and low-risk adjunctive therapy to improve fracture healing.

RESUMO

INTRODUCTION: Proximal femoral fractures are characterized as one of the most common and most painful injuries sustained by patients of all ages and are associated with high rates of oligoanalgesia in the prehospital setting. Current treatments include oral and parenteral opiates and sedative agents, however regional anesthesia techniques for pain relief may provide superior analgesia with lower risk of side effects during patient transportation. The fascia iliaca compartment block (FICB) is an inexpensive treatment which is performed with minimal additional equipment, ultimately making it suitable in prehospital settings. PROBLEM: In adult patients sustaining proximal femoral fractures in the prehospital setting, what is the effect of the FICB on non-verbal pain scores (NVPS), patient satisfaction, success rate, and adverse events compared to traditional analgesic techniques? METHODS: A librarian-assisted literature search was conducted of the Cochrane Database, Ovid MEDLINE, PubMed, Ovid EMBASE, Scopus, and Web of Science indexes. Additionally, reference lists for potential review articles from the British Journal of Anesthesia, the College of Anesthetists of Ireland, the Journal of Prehospital Emergency Care, Annales Francaises d'Anesthesie et Réanimation, and the Scandinavian Journal of Trauma, Resuscitation, and Emergency Medicine were reviewed. Databases and journals were searched during the period from January 1, 1980 through July 1, 2022. Each study was scrutinized for quality and validity and was assigned a level of evidence as per Oxford Center for Evidence-Based Medicine guidelines. RESULTS: Five studies involving 340 patients were included (ie, two randomized control trials [RCTs], two observational studies, and one prospective observational study). Pain scores decreased after prehospital FICB across all included studies by a mean of 6.65 points (5.25 - 7.5) on the NVPS. Out of the total 257 FICBs conducted, there was a success rate of 230 (89.3%). Of these, only two serious adverse events were recorded, both of which related to local analgesia toxicity. Neither resulted in long-term sequelae and only one required treatment. CONCLUSION: Use of FICBs results in a significant decrease in NVPS in the prehospital setting, and they are ultimately suitable as regional analgesic techniques for proximal femur fractures. It carries a low risk of adverse events and may be performed by health care practitioners of various backgrounds with suitable training. The results suggest that FICBs are more effective for pain management than parenteral or oral opiates and sedative agents alone and can be used as an appropriate adjunct to pain management.

RESUMO

Despite best intentions, health care disparities exist and can consequently impact patient care. Few studies have examined the impact of disparities in pediatric orthopedic populations. The current study aimed to determine if the treatment type or complication rates of supracondylar, both-bone forearm, or femur fractures are associated with race, ethnicity, sex, or socioeconomic status. The New York Healthcare Cost and Utilization Project's database was used to identify all pediatric patients treated for supracondylar humerus fractures, both-bone forearm fractures, and femoral shaft fractures in 2016. Risk-adjusted relationships with race, ethnicity, sex, hospital location, and median income by zip code were assessed with multivariable logistic regression. Patients who were non-White, resided in the zip codes with the lowest median income (<$42,999 annually), and were treated in metropolitan areas were more likely to receive nonoperative treatments for supracondylar humerus fractures. Female patients with a femoral shaft fracture were less likely to be treated with open reduction and internal fixation vs intramedullary fixation. Finally, complications were not associated with patient race, sex, or socioeconomic statuses. These findings bring attention to health care disparities in the treatment of common pediatric orthopedic fractures. Further studies investigating the underlying etiology behind these disparities are warranted. [Orthopedics. 2023;46(3):e156-e160.].

RESUMO

Stress fractures likely have a 1-2% incidence in athletes in general. In runners, a more vulnerable population, incidence rates likely range between 3.2 and 21% with female runners having greater susceptibility. The incidence of femoral shaft stress fractures is less well known. New basic and translational science research may impact the way clinicians diagnose and treat femoral stress fractures. By using a fictitious case study, this paper applies bone science to suggest new approaches to evaluating and treating femoral shaft stress fractures in the running population.

RESUMO

PURPOSE: To evaluate the effects of low-intensity pulsed ultrasound (LIPUS) on the quality of femoral fracture callus formation in rats with severe osteoporosis secondary to spinal cord injury (SCI). METHODS: Forty-five male rats were equally divided into three groups: the Sham group underwent sham surgery for SCI followed by surgery for femoral fracture on day ten post-spine surgery; the SCI group sustained a complete transection of the spinal cord and a femoral fracture ten days post-SCI; and the SCI group treated with ultrasound (SCI + US), which also sustained a femoral fracture on day ten post-SCI, concomitant with daily application of LIPUS at the fracture site. RESULTS: At the non-fractured tibias, LIPUS counteracted the SCI-induced bone loss by normalizing the osteoblastic-related gene expression, decreasing resorptive area, increasing trabecular area, and decreasing RANK and RANK-L-positive areas, which resulted in higher cortical volume and stronger tibias. Likewise, LIPUS was effective at restoring bone fracture healing in SCI rats; by promoting endochondral ossification, increasing collagen deposition and OPG-positive-area, decreasing resorptive area, which led to higher density and improved microarchitecture, ultimately resulting in stronger fracture callus. CONCLUSION: At the tibias, LIPUS counteracted the SCI-induced bone loss effects by simultaneously increasing bone formation and decreasing bone resorption. We also evidenced the osteogenic effects of LIPUS at partially restoring the endochondral ossification during callus formation, leading to a newly formed tissue with improved microarchitecture and mechanical integrity. Therefore, LIPUS may be an efficient and non-invasive approach to prevent bone loss and osteoporotic fracture in SCI individuals.

RESUMO

BACKGROUND: Femoral shaft fractures in children are a significant concern. Early hip spica casting is a treatment modality, but its functional outcomes need thorough evaluation. The objective of the study is to assess the functional outcomes of early hip spica management for femoral shaft fractures in children up to 5 years. METHODS: A prospective observational study was conducted at Ayub Teaching Hospital from 15 January 2022 to 26 December 2022. Sixty-two children diagnosed with femoral shaft fractures and treated with early hip spica were enrolled. Exclusion criteria were defined. Functional outcomes, including limb shortening, malunion, skin breakdown, foot drop, and compartment syndrome, were evaluated. Follow-ups were scheduled at 6 weeks, 12 weeks, and 6 months. Data analysis was performed using SPSS software package 25. RESULTS: Of the 45 patients analyzed, 75.56% were males. The average age was 3.56 years. Most fractures were proximal (75.55%) and resulted from motor vehicle accidents (66.67%). Limb shortening was observed in 17.77% of patients, with no significant correlation with age or fracture type. Malunion was rare (1%), and no skin breakdown, foot drop, or compartment syndrome cases were reported. CONCLUSIONS: Early hip spica casting for femoral shaft fractures in children up to 5 years is associated with minimal complications. The findings can guide clinical decisions and patient counselling.

RESUMO

Background: Femoral shaft fractures are common in Malawi, with an annual incidence of 44 per 100,000 people. Inadequate treatment and delayed presentation often result in functional, biopsychosocial, and financial challenges for patients. The purpose of this study was to examine the socioeconomic consequences of femoral shaft fractures for patients in Malawi. Methods: This study of 42 patients was part of a larger study that prospectively examined quality of life. Questionnaires were distributed to patients at 1-year follow-up following femoral shaft fracture treatment. Patients reported pre- and post-injury standard of living and financial well-being. Results: Patients reported relatively high transportation costs to and from the hospital. One year after injury, 17 patients (40%) had not returned to work. Of the 25 (60%) who had returned, 5 (20%) changed jobs due to their injury, all reported decreased productivity. Household income decreased for 29% of patients. 20 (49%) of 41 patients reported food insecurity in the week prior to questionnaire completion. Many patients reported changing their residence, borrowing money, selling personal property, and unenrolling children from school due to financial hardship caused by their injury. Conclusion: While the Malawian public healthcare system is free at the point of care, it lacks the financial risk protection that is essential to universal health coverage (UHC). In this study, we found that the indirect costs of care due to femoral shaft fractures had substantial socioeconomic consequences on the majority of patients and their families. Increased investment of financial and human capital should be made into capacity building and preventative measures to decrease the burden of injury, increase access to care, improve care delivery, and provide financial risk protection for patients with traumatic injuries in Malawi.

RESUMO

This study aims to determine the annual incidence of proximal femoral fractures in Italy in the period between 2001 and 2016 among older adults, and to describe the trends in the clinical management of these cases. Data were retrieved from the National Hospital Discharge records issued by the Italian Ministry of Health and from the Italian Institute for Statistics. The number of hospitalizations increased between 2001 and 2016, while the age-adjusted yearly incidence decreased from 832.2 per 100,000 individuals to 706.2. The median age was 83 years (IQR 78-88) with a large majority of females (76.6%). The type of fracture varied with age in female subjects, with older women more frequently reporting pertrochanteric fractures. Therapeutic strategies for the different types of fracture depended on patients' age. During the study years, improvements in fracture classification and management strategies were observed, with a clear decreasing trend for non-operative solutions. In conclusion, the number of proximal femur fractures in older adults is growing, even if at a lower rate compared to population aging. The Italian surgical practice changed during the study period towards the implementation of the most recent guidelines.

RESUMO

BACKGROUND AND PURPOSE: Distal femoral fractures (DFF) in older patients have mortality rates comparable to fractures of the proximal femur. An ageing population combined with an increasing number of patients undergoing total knee arthroplasty (TKA) will make periprosthetic distal femoral fractures (pDFF) more common. We investigated whether a pre-existing TKA influences mortality rates. PATIENTS AND METHODS: All patients ≥ 60 years registered in the Swedish Fracture Register with a DFF sustained between March 20, 2011 and December 31, 2020 were included. The study cohort comprised 2,725 patients, of which 650 had a pDFF. Unadjusted 90-day and 1-year mortality was estimated via Kaplan-Meier survival curves. A Cox regression model adjusted for age, sex, and treatment modality was used to investigate the association between DFF or pDFF and mortality. RESULTS: Mean age was 80 years and 82% were females. The most common injury mechanism was a simple fall (75%). The pDFF and DFF group were similar with regards to age, sex, and trauma mechanism. Unadjusted 90-day and 1-year mortality was 11% (95% CI 10-12) and 21% (CI 19-23), respectively. Kaplan-Meier survival analysis demonstrated a slightly lower mortality for pDFFs, especially in patients ≤ 70 years. The Cox regression model showed a lower hazard ratio (HR) for mortality in the pDFF group (HR 0.82, CI 0.71-0.94). INTERPRETATION: In a large cohort of patients ≥ 60 years with a distal femoral fracture, mortality rates at 90 days and 1 year post-injury were 11% and 21%, respectively. Periprosthetic fractures were associated with a lower mortality.

RESUMO

There is evidence that mast cells contribute to inflammation induced by hemorrhagic shock, severe tissue injury or sepsis. Mast cells are highly responsive to alarm signals generated after trauma, and release many inflammatory mediators including interleukin-6, a key mediator of posttraumatic inflammation. An overwhelming posttraumatic inflammation causes compromised bone healing; however, the underlying cellular and molecular mechanisms are poorly understood. Recently, we found that mast cells trigger local and systemic inflammation after isolated fracture leading to uneventful bone repair. Here, we investigated whether mast cells critically contribute to trauma-induced compromised bone healing. Male Mcpt5-Cre+ R-DTA mice, which lack connective tissue type mast cells, and their mast cell-competent Cre- littermates underwent a femur fracture with/without thoracic trauma. Posttraumatic systemic and local inflammation and bone repair were assessed 3 h and 21 d post injury. Both, the systemic and pulmonary inflammation was significantly increased in mast cell-competent mice upon combined trauma compared to isolated fracture. In mast cell-deficient mice, the increase of inflammatory mediators in the circulation induced by the severe trauma was abolished. In the bronchoalveolar lavage fluid, the trauma-induced increase of inflammatory cytokines was not reduced, but the neutrophil invasion into the lungs was significantly diminished in the absence of mast cells. Locally in the fracture hematoma, mast cell-competent mice displayed reduced inflammatory mediator concentrations after combined trauma compared to isolated fracture, which was abolished in mast cell-deficient mice. Notably, while combined trauma resulted in compromised bone repair in mast cell-competent mice, indicated by significantly reduced bone and increased cartilage fracture callus contents, this was abolished in Mcpt5-Cre+ R-DTA mice. Therefore, mast cells contribute to trauma-induced compromised bone repair and could be a potential target for new treatment options to improve fracture healing in multiply injured patients.

RESUMO

The purpose of this study was to analyze the regenerative capacity of mesenchymal stem cells (MSCs) in the treatment of fractures. MSCs extracted from patients with osteoporotic hip fractures or hip osteoarthritis undergoing hip replacement surgeries were cultured and injected into mice with femoral fracture. Two experimental models were established, one for the systemic administration of MSCs (n = 29) and another one for local administration (n = 30). Fracture consolidation was assessed by micro-CT and histology. The degree of radiological consolidation and corticalization was better with MSCs from osteoporosis than from osteoarthritis, being significant after systemic administration (p = 0.0302 consolidation; p = 0.0243 corticalization). The histological degree of consolidation was also better with MSCs from osteoporosis than from osteoarthritis. Differences in histological scores after systemic infusion were as follows: Allen, p = 0.0278; Huo, p = 0.3471; and Bone Bridge, p = 0.0935. After local administration at the fracture site, differences in histological scores were as follows: Allen, p = 0.0764; Huo, p = 0.0256; and Bone Bridge, p = 0.0012. As osteoporosis and control groups were similar, those differences depended on an inhibitory influence by MSCs from patients with osteoarthritis. In conclusion, we found an unexpected impairment of consolidation induced by MSCs from patients with osteoarthritis. However, MSCs from patients with osteoporosis compared favorably with cells from patients with osteoarthritis. In other words, based on this study and previous studies, MSCs from patients with osteoporosis do not appear to have worse bone-regenerating capabilities than MSCs from non-osteoporotic individuals of similar age.

RESUMO

The aim of this study was to investigate whether HUCMSCsWnt10b could promote long bone fracture healing. Commercially-available HUCMSCsEmp (human umbilical cord mesenchymal stem cells transfected with empty vector) in hydrogel, HUCMSCsWnt10b in hydrogel and HUCMSCsWnt10b with the Wnt signaling pathway inhibitor IWR-1 were transplanted into the fracture site in a rat model of femoral fracture. We found that transplantation of HUCMSCsWnt10b significantly accelerated bone healing in a rat model of femoral fracture. Meanwhile, three-point bending test proved that the mechanical properties of the bone at the fracture site in the HUCMSCWnt10b treatment group were significantly better than those of the other treatment groups. To understand the cellular mechanism, we explored the viability of periosteal stem cells (PSCs), as they contribute the greatest number of osteoblast lineage cells to the callus. In line with in vivo data, we found that conditioned medium from HUCMSCsWnt10b enhanced the migration and osteogenic differentiation of PSCs. Furthermore, conditioned medium from HUCMSCsWnt10b also induced endothelial cells to form capillary-like structures in a tube formation assay, which was blocked by SU5416, an angiogenesis inhibitor, suggesting that enhanced vessel formation and growth also contribute to accelerated hard callus formation. In summary, our study demonstrates that HUCMSCsWnt10b promote fracture healing via accelerated hard callus formation, possibly due to enhanced osteogenic differentiation of PSCs and vessel growth. Therefore, HUCMSCsWnt10b may be a promising treatment for long bone fractures.

BACKGROUND: Diaphyseal femur fractures contribute up to 40% of paediatric orthopaedic admissions with the World Health Organisation data showing youth are particularly vulnerable and road traffic injuries are the leading cause of death for children and young adults. Different mechanisms results to these injuries and they vary with age and geographical location of the patient. Understanding the incidence, mechanism and pattern of these injuries allows planning for preventive measures and treatment to meet modern day patient demands, generation of appropriate and timely protocols with minimum social and economic burden to the patient and family. OBJECTIVES AND METHODS: A hospital based cross sectional study was conducted using the orthopaedic department patient registry among children aged under 18 years admitted from 2014-2018. Our research question was to determine the epidemiology of diaphyseal femur fractures and coexisting associated injuries among admitted paediatric orthopaedic patients. Patient files were reviewed from the medical records department and a data collecting sheet was used to record demographics and injury data. Odds ratios with 95% confidence intervals for associated injuries in paediatric diaphyseal femur fractures were estimated using multivariable logistic regression model. RESULTS: We found the prevalence of diaphyseal femur fracture among paediatric orthopaedic admissions was 18% with the majority 111 (68.5%) being males. The leading injury mechanism was a fall (57.4%) followed by road traffic injuries (35.8%) out of which 48.3% resulted from pedestrian vs motorcycle accidents. Traumatic brain injury (TBI) was the most common associated injuries accounting for 69% of these injuries with the majority 79% occurring in patients aged 6 years and older. With age specific analysis, children in 6-12 years and 13-18 years age groups, had 8 and 11 times higher odds for associated injuries (OR 8.25, 95% CI, 1.04-65.31) p = 0.046 and (OR 10.54, 95% CI, 1.26-88.31) p = 0.031 respectively compared to those younger ≤ 2 years. Road traffic related injuries had 17 times higher odds of associated injuries when compared to fall (OR 16.73, 95% CI, 6.28-44.57) p < 0.001. 112 (69.1%) of femur fractures were treated by non-operative method out of this 90 (55.6%) by traction with delayed Spica application. The overall mean duration of hospital stay was 18.5 ± 11 days. CONCLUSION: Pedestrian vs motorcycle injuries was the leading specific cause of paediatric diaphyseal femur fractures with TBI being the common associated injury. Non-operative management was the most utilized treatment plan and contributed to ten times higher odds for a longer duration of hospital stay. Initiatives to insure children safety on roads should be strengthened in order to reduce/eliminate this burden. Application and practice of current evidence based clinical guidelines and recommendations is paramount for timely and appropriate treatment of these injuries.

RESUMO

Complex distal femoral fracture (DFF) in the elderly patient is an infrequent but challenging scenario. In these fragile patients, DFF is associated with a high rate of medical complications and mortality. The optimum treatment remains controversial. Our aim is to propose our standard treatment, describe our results and discuss its clinical relevance. We describe three cases of elderly and fragile patients with multiple comorbidities who suffered a complex DFF after low energy trauma. They were successfully treated through a primary arthroplasty with distal femoral replacement (DFR). All the three patients presented early full weight-bearing mobilization (average time to first ambulation was five days), good functional outcome (mean knee range of motion was 103°) and short hospital length of stay (mean of ten days). According to our experience, primary arthroplasty with DFR could be a good therapeutic option for complex DFF in elderly patients.(AU)

RESUMO

BACKGROUND: Open long-bone fractures represent a complex injury within the trauma system. Guidelines recommend antibiotics be given within 60 minutes of patient arrival to the emergency department. We sought to measure and improve the timeliness of antibiotic administration at the patient, hospital, and population level within a collaborative quality initiative. METHODS: Trauma collaborative quality initiative data (January 2017 to December 2020) were analyzed from 34 American College of Surgeons Committee on Trauma verified level 1 and level 2 trauma centers. Inclusion criteria were adult patients (≥16 years), injury severity score ≥5, and open tibia or femur fracture. After the baseline year, hospitals were scored annually on a pay-for-performance metric based on patients receiving antibiotics within 120 minutes of emergency department arrival. Univariate tests examined the differences between baseline and subsequent year(s) performance. A multivariable logistic regression assessed the factors associated with meeting this target time. RESULTS: There were 2,624 patients with an open long-bone fracture. In the baseline year (2017), 76.9% of patients received antibiotics in ≤120 minutes, with a mean time of 57.9 ± 63.3 minutes. After implementing collaborative quality initiative-wide targets, performance significantly improved in subsequent years (2018, 2019, 2020). The collaborative quality initiative achieved their goal of ≥85% of patients receiving antibiotics in ≤120 minutes in 2019 (87.9%) and 2020 (88.5%), with a mean time of 43.3 ± 54.8 minutes (P < .05 vs 2017). CONCLUSION: A pay-for-performance process measure within a statewide trauma collaborative quality initiative improved the timely administration of antibiotics to patients with open fractures. Work remains to align compliance with the guideline target of <60 minutes and to identify factors involved in the delay of administration.

RESUMO

BACKGROUND: There is limited data on transporting small children in hip spica casts used to treat pediatric femur fractures. Specific challenges include the fixed position of the body in the casted position and the increased size of the child due to cast thickness. Additionally, children less than 2 years old are recommended to be rear facing during transportation. This traveling position requires seats that are specifically designed to accommodate the small size of the child as well as accommodate the rear facing position. While seats able to accommodate casted children are available, it is unclear if they provide adequate protection in side impact collisions for rear facing spica casted infants. Therefore, the aim of this study was to evaluate traumatic injury metrics in a side impact collision model where a spica casted infant crash dummy was restrained in currently available car seats. METHODS: Two seats designed for spica casted children (R82 Quokka, Merritt Wallenberg) and two traditional car seats (Britax Emblem, Graco Sequel) able to accommodate a casted one-year-old crash test dummy were identified. Side impact collision testing was performed with the dummy positioned in the rear facing position and injury metrics recorded. RESULTS: Testing identified contact between the dummy's head and the door panel for a specialty spica car seat without protective side-wings for the head. All other seats contained side wings and prevented door-head contact. CONCLUSIONS: Casted children should be transported in a seat able to accommodate the cast and safely restrain them. Our results demonstrate the importance of side wing protection in any seat used to transport these children as side bolsters may help decrease the potential for head contact with the door and lower the risk of severe head injury.

RESUMO

Objective: To explore the application of multimode health education combined with humanistic care in pain management of patients with femoral fracture and its influence on VAS score. Methods: A total of 120 patients with femoral fracture admitted in our hospital (May 2017-May 2021) were selected as the research objects. The patients who received routine health education were included into the routine group, and the patients who received multimode health education combined with humanistic care were included into the combined group, with 60 cases in each group. The pain management effect of the two groups was compared after nursing intervention. Results: No significant difference was found in age, BMI, fracture sites, gender, education degree, and residence between the two groups (P > 0.05). The awareness rate of health knowledge of the combined group was as high as 93.33%, which was obviously higher than that of the routine group (P < 0.05). Compared with the routine group, excellent rates of sitting durability and joint range of motion in the combined group were obviously higher (P < 0.05), and poor rates of sitting durability and joint range of motion in the combined group were obviously lower (P < 0.05). Compared with the routine group, VAS scores of the combined group at 1 d, 2 d, and 3 d after admission and at 1 d, 2 d, and 3 d after surgery were remarkably lower (P < 0.05). Compared with the routine group, compliance of exercise, medical waist belt using, and working posture of the combined group 1 week, 1 month, and 6 months after surgery was obviously higher (P < 0.05). Compared with the routine group, the scores of Rasmussen and Johner-Wruhs of the combined group 6 months after surgery were conspicuously higher (P < 0.05). Conclusion: The application of multimode health education combined with humanistic care in pain management of patients with femoral fracture can effectively relieve pain, improve the awareness rate of health knowledge, promote the recovery of lower limb function, and enhance the prognosis of quality of life for patients.
