RESUMO

INTRODUCTION: Although a well-established component of bone metabolism, the efficacy and safety of vitamin D supplementation for the prevention of fractures in elderly healthy individuals is still unclear. PURPOSE: To perform a meta-analysis comparing vitamin D supplementation with placebo and its contributions on fracture incidence. METHODS: This meta-analysis was registered in the International Prospective Register of Systematic Reviews (PROSPERO), under protocol CRD42023484979. We systematically searched PubMed, Embase, and Cochrane Central databases from inception to November 2023 for randomized controlled trials (RCTs) comparing vitamin D supplementation versus placebo in individuals with 60 years of age or more and without bone related medical conditions such as cancer and osteoporosis. RESULTS: Seven RCTs with 71,899 patients were included, of whom 36,822 (51.2%) were women. There was no significant difference in total fracture incidence (RR 1.03; 95% CI 0.93-1.14; p = 0.56; I2 = 58%) between groups or subgroups. However, women had an increased risk for hip fractures (164 vs. 121 events; RR 1.34; 95% CI 1.06-1.70; p = 0.01; I2 = 0%). There was no significant difference in non-vertebral fractures, osteoporotic fractures development, or falls (RR 1.02; 95% CI 0.94-1.12; p = 0.6; I2 = 47%; RR 0.97; 95% CI 0.87-1.08; p = 0.63; I2 = 0%; RR 1.01; 95% CI 0.97-1.04; p = 0.66; I2 = 55%, respectively). CONCLUSION: Vitamin D supplementation does not reduce the total fracture development rate in the elderly healthy population, and it may increase the incidence of hip fractures among elderly healthy women. This finding suggests refraining from prescribing high intermittent doses of vitamin D, without calcium, to individuals aged 60 or older with unknown vitamin D serum concentration or osteoporosis status and inadequate calcium intake.

RESUMO

PURPOSE: We aim to compare interfragmentary compression with the position osteosynthesis in the fixation of different femoral neck fractures (FN) in synthetic bones subjected to vertical load. METHODS: Forty-two synthetic femurs were subjected to neck fractures and separated into 3 groups according to the Pauwels classification: Pauwels I had 6 units (PI); Pauwels II, 24 units, with and without comminution (PII); and Pauwels III, 12 units, with and without comminution (PIII). After, they were fixed with 2 different ways: three 7, 0 mm cannulated lag screws (CSs) versus three 6, 5 mm solid fully threaded screws (SSs). Screws positioning was oriented by the Pauwels classification: inverted triangle or crossed screws. All specimens were submitted to vertical loading until failure. RESULTS: The average force was 79.4 ± 22.6 Kgf. The greatest one was recorded in model 1 (135.6 Kgf), and the lowest in model 41 (39.6 Kgf). CSs and SSs had similar resistance until failure (p = 0.2). PI showed heightened resistance and PIII showed a worse response (p < 0,01). CSs had better performance in PIII (p = 0.048). Comminution and screws orientation caused no difference on peak force (p = 0.918 and p = 0.340, respectively). CONCLUSIONS: In synthetic bones, the resistance of a femoral neck fracture osteosynthesis using a 7, 0 mm cannulated lag screw or 6, 5 mm solid fully threaded screw are similar. There was no loss of efficiency with comminution in the femoral neck. Osteosynthesis resistance decreased with the verticalization of the fracture line and, in the more vertical ones, interfragmentary compression with CSs was more resistant than positional osteosynthesis with SSs.

RESUMO

Objectives This study evaluated pain intensity in elderly subjects with hip fractures admitted to the emergency sector and undergoing preoperative pericapsular nerve group (PENG) block. Additionally, the degree of tolerable hip flexion was assessed. Methods A prospective, randomized, and controlled clinical trial with parallel groups. The control group consisted of elderly subjects with hip fractures undergoing standardized intravenous systemic analgesia. The intervention group consisted of elderly patients with hip fractures undergoing PENG block and standardized systemic analgesia. The groups were evaluated at rest and during movement using the Pain Assessment in Advanced Dementia (PAINAD) scale. We determined pain intensity and reduction, in addition to the degree of tolerable flexion of the fractured hip. All patient assessments occurred before the medication or block administration and at 45 minutes, 12, 24, and 36 hours postmedication or block. Results Preoperatively and 24 hours after PENG block, elderly subjects with hip fracture showed a significant reduction in pain at rest or movement compared to control patients ( p < 0.05), with 60% of patients assessed at rest demonstrating desirable pain reduction (≥50%) and only 13.3% of the control group achieving the desired pain reduction. During movement, after undergoing PENG block, 40% of subjects demonstrated the desired pain reduction and no patient from the control group. The intervention group also showed a significant improvement in the tolerable hip flexion group ( p < 0.05). Conclusion Preoperative PENG block in elderly subjects with hip fractures admitted to the emergency sector provided a significant reduction in pain compared with the control group.

RESUMO

Objective: Hip fractures in older adults have the highest impact on the patient's health. These injuries result in many complications, reducing functional capability, quality of life, and life expectancy. This study aimed to provide more epidemiological data on the outcomes of these fractures in nonagenarians from a large city treated at a tertiary hospital. Methods: This study consisted of medical record reviews and interviews. Results: In this study, 76 patients underwent 82 surgeries. The mean age of the patients was 92.5 years. Ninety percent of the subjects were female. The patients spent 10.4 days in hospital. Surgery occurred on average 2.3 days after hospitalization. Regarding fractures, 46 were trochanteric (56%), and 34 affected the femoral neck (41.5%). Forty-one surgeries used the short proximal femoral nail (50%), and 18 were partial hip replacements (22%). During hospitalization, 46 patients (55%) had no complications, excluding episodes of delirium, and seven patients (9%) died. Forty-two subjects completed the one-year postoperative follow-up period, with 56% alive and 44% dead. Conclusions: Treating hip fractures in older patients is challenging. Our goal must focus on helping these subjects receive the quickest and least aggressive treatment possible and start mobilization early. We hope the data presented in this study can lead to a better understanding of the characteristics of our nonagenarian population with hip fractures and seek the best possible treatment for them.

RESUMO

BACKGROUND: Hip fractures in the older adults lead to increased morbidity and mortality. Although a low bone mineral density is considered the leading risk factor, it is essential to recognize other factors that could affect the risk of hip fractures. This study aims to evaluate the contribution of clinical characteristics, patient-reported outcomes, and muscle and aerobic capacity for hip fractures in community-dwelling older adults. METHODS: This is a retrospective cohort study with real world-data from subjects ≥ 60 years old attending an outpatient clinic in Minas Gerais, Brazil, from May 1, 2019, to August 22, 2022. Data about clinical characteristics (multimorbidity, medications of long-term use, sedative and or tricyclic medications, number of falls), patient-reported outcomes (self-perception of health, self-report of difficulty walking, self-report of vision problems, and self-report of falls) and muscle and aerobic capacity (calf circumference, body mass index, and gait speed) were retrieved from an electronic health record. The association of each potential risk factor and hip fracture was investigated by a multivariable logistic regression analysis adjusted for age and sex. RESULTS: A total of 7,836 older adults were included with a median age of 80 years (IQR 72-86) and 5,702 (72.7%) were female. Hip fractures occurred in 121 (1.54%) patients. Multimorbidity was associated with an increased risk of hip fracture (OR = 1.12, 95%CI 1.06-1.18) and each episode of fall increased the chance of hip fracture by 1.7-fold (OR = 1.69, 95%CI 1.52-1.80). Patient-reported outcomes associated with increased fracture risk were regular or poor self-perception of health (OR = 1.59, 95%CI 1.06-2.37), self-report of walking difficulty (OR = 3.06, 95%CI 1.93-4.84), and self-report of falls (OR = 2.23, 95%CI 1.47-3.40). Body mass index and calf circumference were inversely associated with hip fractures (OR = 0.91, 95%CI 0.87-0.96 and OR = 0.93, 95%CI 0.88-0.97, respectively), while slow gait speed increased the chance of hip fractures by almost two-fold (OR = 1.80, 95%CI 1.22-2.66). CONCLUSION: Our study reinforces the importance of identified risk factors for hip fracture in community-dwelling older adults beyond bone mineral density and available fracture risk assessment tools. Data obtained in primary care can help physicians, other health professionals, and public health policies to identify patients at increased risk of hip fractures.

RESUMO

ABSTRACT Objective To describe and analyze the aspects regarding the cost and length of stay for elderly patients with bone fractures in a tertiary reference hospital. Methods A cross-sectional retrospective study using data obtained from medical records between January and December 2020. For statistical analysis, exploratory analyses, Shapiro-Wilk test, χ2 test, and Spearman correlation were used. Results During the study period, 156 elderly patients (62.2% women) with bone fractures were treated. The main trauma mechanism was a fall from a standing height (76.9%). The most common type of fracture in this sample was a transtrochanteric fracture of the femur, accounting for 40.4% of cases. The mean length of stay was 5.25 days. The total cost varied between R$2,006.53 and R$106,912.74 (average of R$15,695.76) (updated values). The mean daily cost of hospitalization was R$4,478.64. A positive correlation was found between the length of stay and total cost. No significant difference in cost was observed between the two main types of treated fractures. Conclusion Fractures in the elderly are frequent, resulting in significant costs. The longer the hospital stay for treatment, the higher the total cost. No correlation was found between total cost and number of comorbidities, number of medications used, and the comparison between the treatment of transtrochanteric and femoral neck fractures.

RESUMO

Objective To describe and evaluate the accuracy of the pericapsular nerve group (PENG) block technique with no ultrasound guidance. Method Series of 40 infiltrations in patients with hip pain undergoing outpatient follow-up in the hip surgery group or admitted to the emergency room from a hospital in São Paulo, SP, Brazil. The hip PENG technique was guided by palpable anatomical pelvic structures, with no ultrasound orientation for needle positioning, using the equipment only to check the correct location after an unguided puncture. Results In the 40 hips infiltrated from 35 patients with a mean age of 59.2 years, the success rate was 85%. Among the mispositioned cases, 71.4% occurred in the first 13 applications and 28.6% in the subsequent 27 applications. In all patients, the neurovascular bundle was in the medial third of the pen-made demarcation. Even in cases with a failed needle location, the distance from the neurovascular bundle was safe. A single adverse effect occurred, with spontaneous improvement of the femoral nerve apraxia within two days. Conclusion Unguided PENG block is a viable technique for a physician knowledgeable about its application in services with no ultrasound availability.

RESUMO

Introduction Hip fracture is one of the main causes of morbidity and mortality among the elderly population. In Colombia there is a shortage of scientific literature on the perioperative management of this population of patients. Objective To describe the perioperative management of hip fracture patients at a tertiary university hospital in Cali, Colombia. Methods An observational study was conducted with relational scope of a historical cohort of patients with hip fracture who underwent surgical management between January 2018 and June 2022. A non-probability sampling method was used and contingency tables were designed aimed at describing the relationship between the patients' characteristics and the postoperative outcomes. Results 235 patients were included, of which 57 % were males. The mean age was 79 years and 49.8 % were classified as ASA III or higher. Spinal anesthesia was the most commonly used technique in 63.4 % of the cases. The most frequent outcomes were delirium in 17.9 %, and acute kidney failure in 6.8 %. 83.4 % of the patients underwent surgery within 48 hours of admission to the emergency department and intra-hospital mortality was 2.6 %. Conclusions The results of this study provide relevant information to identify opportunities for improvement and their implementation, such as the reduction in the time elapsed until surgical management and the development of care protocols in the region.

RESUMO

Background: The World Health Organization (WHO) declared COVID-19 a pandemic on March 11, 2020. Patients who tested positive for COVID-19 experienced a higher overall rate of post-surgical complications and hospital mortality. Objective: To compare the asociation of post-surgical complications presented in post-surgical hip patients with and without history of COVID-19 infection. Material and methods: Prospective cohort study. The inclusion criteria were: post-hip surgery adults with and without a history of COVID-19 infection who attended their post-surgical follow-up consultation. The association of post-surgical complications in both groups was studied. The association of complications was analyzed with the chi-squared statistical test, and the effect size with Cramer's V test. Results: The association of complications and a history of COVID-19 infection was moderate, with a chi-squared of 2.55, V Cramer of 0.23. The most frequent complication was aseptic loosening of prosthetic components. The pre-surgical diagnosis and its association with both groups had a chi-squared of 10.07, and a V Cramer of 0.45, at the expense of hip fracture. Conclusions: A history of COVID-19 infection may be associated with the presence of post-surgical complications. Aseptic loosening of prosthetic components was the most frequent complication in both groups of patients, and hip fracture was the main pre-surgical diagnosis.

Introducción: la Organización Mundial de la Salud (OMS) declaró la COVID-19 como pandemia el 11 de marzo de 2020. Los pacientes con COVID-19 tuvieron una tasa mayor de complicaciones postquirúrgicas en cirugía de cadera. Objetivo: comparar la presencia de complicaciones posquirúrgicas en pacientes postoperados de cadera con y sin antecedente de infección por COVID-19. Material y métodos: estudio de cohorte prospectiva. Los criterios de inclusión fueron: adultos postoperados de cirugía de cadera con y sin antecedente de infección por COVID-19 que acudieron a su consulta postquirúrgica de control. Se estudió la asociación de las complicaciones postquirúrgicas en ambos grupos y se analizó con la prueba estadística chi cuadrada y el tamaño del efecto con la prueba V de Cramer. Resultados: la asociación de complicaciones y el antecedente de infección por COVID-19 fue moderada, chi cuadrada de 2.55, V de Cramer de 0.23. La complicación más frecuente fue el aflojamiento aséptico de componentes protésicos. El diagnóstico prequirúrgico y su asociación con ambos grupos tuvieron una chi cuadrada de 10.07, V de Cramer de 0.45, a expensas de la fractura de cadera. Conclusiones: el antecedente de infección por COVID-19 puede asociarse con la presencia de complicaciones postquirúgicas. El aflojamiento aséptico de componentes protésicos fue la complicación más frecuente en ambos grupos de pacientes y la fractura de cadera el diagnóstico prequirúrgico principal.

RESUMO

Background: The most widely used fixation system for transtrochanteric fractures is the dynamic hip screw system, which has a failure prevalence of 10 to 17% and it is associated with the presence of clinical and radiographic factors. Objective: To evaluate the association of clinical and radiographic factors with the failure of the screw system in post-operative patients for transtrochanteric hip fracture. Material y methods: A case-control study was carried out. The inclusion criteria were: patients > 18 years, who underwent surgery due to transtrochanteric fracture, were treated with the hip screw system, and who attended the Trauma Service. The patient with failure of the hip screw system was selected as the case and the patient without failure of the system as control. The variables analyzed in these groups were: age, gender, body mass index and radiographic variables. Statistical analysis was performed with chi-squared and Mann-Whitney U. Results: 163 patients (median 73 years), 20 cases and 143 controls, were included. The radiographic factors with a significant association with hip screw system failure were the AO classification of fractures (p < 0.001), the tip apex distance (p = 0.03), the calcar-referenced tip apex (p = 0.02), the position of the screw (p < 0.001), and quality of reduction (p < 0.003). Clinical factors did not show a significant association. Conclusions: Radiographic factors are associated with failure in the hip screw system in patients in post-operative care due to transtrochanteric fracture.

Introducción: el sistema de fijación más usado para fracturas transtrocantéricas es el sistema del tornillo dinámico de cadera, el cual tiene una prevalencia de falla del 10 al 17% y se asocia a la presencia de factores clínicos y radiográficos. Objetivo: evaluar la asociación de los factores clínicos y radiográficos con la falla del sistema del tornillo en pacientes postoperados de fractura transtrocantérica de cadera. Material y métodos: se hizo un estudio de casos y controles. Los criterios de inclusión fueron: pacientes > 18 años, postoperados de fractura transtrocantérica, tratados con el sistema del tornillo de cadera, que acudieron a la consulta de Traumatología. Se seleccionó como caso al paciente con falla del sistema del tornillo de cadera y como control al paciente sin falla de este. Las variables analizadas en los grupos fueron la edad, el género, el índice de masa corporal y las variables radiográficas. El análisis estadístico se hizo con chi cuadrada y U de Mann-Whitney. Resultados: se incluyeron 163 pacientes (mediana de 73 años), 20 casos y 143 controles. Los factores radiográficos con asociación significativa con la falla del sistema del tornillo de cadera fueron la clasificación AO de la fractura (p < 0.001), la distancia punta-ápex (p = 0.03), punta ápex calcar (p = 0.02), la posición del tornillo (p < 0.001) y la calidad de la reducción (p < 0.003). Los factores clínicos no mostraron asociación significativa. Conclusiones: los factores radiográficos se asocian con la falla en el sistema del tornillo de cadera en pacientes postoperados de fractura transtrocantérica.

RESUMO

Objectives: To describe the regional distribution of hospital admission authorizations (HAA), hospitalization costs (HC), the average length of stay (LOS), and mortality rates (MR) related to primary total hip arthroplasties (THA) funded by the Brazilian Health Unic System (SUS) from 2012 to 2021. Methods: Descriptive cross-sectional study using secondary data of public domain obtained from the Department of Informatics of SUS (DATASUS) database website. Results: A total of 125,463 HAA were released with HC of 552,218,181.04 BRL in the evaluated period. The average LOS was of 6.8 days. MR was 1.62%. Conclusion: The regional distribution of HAA was 65,756 (52%) in the Southeast; 33,837 (27%) in the South; 14,882 (12%) in the Northeast; 9,364 (8%) in Midwest; and 1,624 (1%) in North - in 2020 there was a sharp decrease of the released HAA, probably due to the COVID-19 pandemic. HC was 293,474,673.20 BRL in the Southeast; 144,794,843.11 BRL in the South; 61,751,644.36 BRL in the Northeast; 45,724,353.80 BRL in the Midwest; and 6,472,666.57 BRL in the North. The average LOS was 6.7 in the Southeast; 5.3 in the South; 9.2 in the Northeast; 7.6 in the Midwest; and, 13.6 in the North. MR was as follows: Southeast=1.88%; South=1.07%; Northeast=1.83%; Midwest=1.44%; and North=1.47%. Evidence Level III; Retrospective Comparative Study .

Objetivos: Descrever a distribuição regional das autorizações de internação hospitalar (AIH), custos de internação (CI), tempo médio de permanência (TMP) e taxa de mortalidade (TM) relacionados às artroplastias totais de quadril (ATQ) primárias financiadas pelo Sistema Único de Saúde (SUS) de 2012 a 2021. Métodos: Estudo transversal descritivo utilizando dados secundários de domínio público obtidos no site do banco de dados do Departamento de Informática do SUS (DATASUS).

RESUMO

Introducción: durante el postoperatorio por cirugía de cadera, el delírium es la complicación más frecuente en los pacientes ancianos, con una alta incidencia y prevalencia, la cual lleva a una alta morbimortalidad en ellos. Objetivo: identificar los factores asociados con delírium en pacientes ancianos durante su posto-peratorio de cirugía por fractura de cadera. Materiales y métodos: se realizó un estudio observacional analítico de corte retrospectivo con pacientes hospitalizados por el grupo de Ortogeriatría en el Hospital Universitario San Ignacio en Bogotá (Colombia), entre enero de 2017 y septiembre de 2020. Resultados: se incluyeron 210 personas, en quienes se documentó una incidencia de delírium del 28.57 %. En el análisis bivariado, las variables con asociación estadísticamente significativa fueron edad, dependencia, demencia previa, malnutrición, polifarmacia y tipo de anestesia. Sin embargo, en el análisis multivariado, las dos variables con asociación estadísticamente significativa fueron edad (OR: 1.05; IC95 %: 1.01-1.10; p = 0.014) y demencia (OR: 2.83; IC95 %: 1.28-6.27; p = 0.010). Conclusión: las variables asociadas con delírium reportadas en el estudio concuerdan con la literatura ya publicada. Esto abre las puertas a futuras investigaciones no solo para identificar nuevos o más factores asociados, sino también para adoptar medidas en conjunto con los programas de ortogeriatría, a fin de intervenir estos factores y, de esta manera, poder disminuir la incidencia y prevalencia del delírium y, por ende, su morbimortalidad.

Introduction: Post-operative delirium after hip surgery is the most common complication among the elderly, with a high incidence and prevalence, which leads to high morbidity and mortality rates among them. Objective: To identify the main factors associated with post-operative delirium after hip surgery among older adults. Materials and methods: a retrospective analytical observational study was conducted using data from patients hospitalized by the Orthogeriatric group at the San Ignacio University Hospital in Bogotá, Colombia, between January 2017 and September 2020. Results: 210 people were included in the study, with a documented incidence of delirium of 28.57% was documented. In the bivariate analysis, the variables with a statistically significant association with delirium were age, dependency, previous dementia, malnutrition, polypharmacy, and type of anesthesia used in the procedure. Nonetheless, in a multivariate analysis, the two variables with a statistically significant association were age (OR: 1.05; 95%CI: 1.01-1.10; p = 0.014) and dementia (OR: 2.83; 95% CI: 1.28-6.27; p = 0.010). Conclusion: the variables associated with postoperative delirium reported in our study align with the existing literature. This opens doors to future research not only to identify new or more risk factors, but also to adopt measures, jointly with the Orthogeriatric programs, to intervene such factors so that the incidence and prevalence of delirium can be reduced, and therefore, reduce the morbidity and mortality among the elderly.

Introdução: o delirium no pós-operatório de cirurgia de quadril é a complicação mais frequente em pacientes idosos, com alta incidência e prevalência, o que leva a alta morbimortalidade nos mesmos e, assim, o objetivo deste estudo foi identificar os fatores associados ao delirium em pacientes idosos no pós-operatório de cirurgia de fratura de quadril. Materiais e métodos: foi realizado um estudo observacional analítico retrospectivo com pacientes internados pelo grupo de Ortogeriatria do Hospital Universitário San Ignacio, em Bogotá, Colômbia, entre janeiro de 2017 e setembro de 2020. Resultados: foram incluídas 210 pessoas, nas quais foi documentado incidência de delirium de 28,57%. Na análise bivariada, as variáveis com associação estatisticamente significativa foram idade, dependência, demência prévia, desnutrição, polifarmácia e tipo de anestesia. Porém, na análise multivariada, as duas variáveis com associação estatisticamente significativa foram idade (or: 1,05; Ic 95% 1,01-1,10; p: 0,014) e demência (or: 2,83; Ic 95% 1,28-6,27, p: 0,010). Conclusão: as variáveis associadas ao delirium relatadas em nosso estudo concordam com a literatura publicada anteriormente. Isso abre as portas para pesquisas futuras não só para identificar novos ou mais fatores associados, mas também para adotar medidas em conjunto com programas de ortogeriatria para poder intervir nesses fatores e, assim, reduzir a incidência e prevalência de delirium e, portanto, a morbimortalidade

RESUMO

Introducción: Las fracturas osteoporóticas, especialmente de cadera y columna, conllevan una significativa morbimortalidad, y el riesgo de fractura de cadera aumenta en un 50% tras una fractura previa. A nivel global y en Chile, persiste una baja tasa de tratamiento de la osteoporosis post fractura. La iniciativa "Capture the Fracture" de la International Osteoporosis Foundation propone prácticas óptimas, incluyendo Servicios de Enlace Post Fractura (FLS); sin embargo, en Chile, sólo existen dos FLS, ambos en el sector privado. Objetivo: Este estudio busca implementar el primer FLS en el ámbito público, específicamente en el Hospital Clínico Dra. Eloísa Díaz de La Florida. La metodología se basa en el Modelo Lógico, enfatizando la relevancia del recurso humano, especialmente una enfermera coordinadora. Resultados: Los resultados identifican el problema, recursos necesarios, acciones clave y metas a corto, mediano y largo plazo. Factores externos como el entorno hospitalario y colaboración con programas existentes se consideran. Se presenta un esquema gráfico del Modelo Lógico y se proponen indicadores de evaluación. Discusión: Es relevante abordar las fracturas por fragilidad como un problema de salud pública y en cuanto a esto, se destaca la aceptación de nuestro proyecto para su implementación por parte de las autoridades hospitalarias. Se espera que esta iniciativa inspire a otros centros de salud pública en Chile a implementar servicios similares, contribuyendo a cerrar la brecha de tratamiento y mejorar la calidad de vida de los pacientes.

Introduction: Osteoporotic fractures, especially of the hip and spine, entail significant morbidity and mortality, with a 50% increased risk of hip fracture following a prior fracture. Globally - and in Chile, a low rate of post-fracture osteoporosis treatment persists. The International Osteoporosis Foundation's "Capture the Fracture" initiative advocates optimal practices, including Fracture Liaison Services (FLS); however, in Chile, there are only two FLS, both in the private healthcare system. Objective: This study aims to implement the first FLS in the public domain, specifically at the Dra. Eloísa Díaz Clinical Hospital, at Santiago. The methodology is based on the Logic Model, emphasizing the importance of human resources, especially a coordinating nurse. Results: The findings identify the problem, necessary resources, key actions, and short, medium, and long-term goals. External factors such as the hospital environment and collaboration with existing programs are considered. A graphical representation of the Logic Model is presented, along with proposed evaluation indicators. Discussion: Addressing fragility fractures as a public health issue is pertinent, and hospital authorities' acceptance of our project for implementation is highlighted. This initiative is anticipated to inspire other public health centers in Chile to implement similar services, contributing to closing the treatment gap and enhancing patients' quality of life.

RESUMO

Objective To evaluate the biomechanical capacity of two forms of fixation for Pipkin type-II fractures, describing the vertical fracture deviation, the maximum and minimum principal stresses, and the Von Mises equivalent stress in the syntheses used. Materials and Methods Two internal fasteners were developed to treat Pipkin type-II fractures through finite elements: a 3.5-mm cortical screw and a Herbert screw. Under the same conditions, the vertical fracture deviation, the maximum and minimum principal stresses, and the Von Mises equivalent stress in the syntheses used were evaluated. Results The vertical displacements evaluated were of 1.5 mm and 0.5 mm. The maximum principal stress values obtained in the upper region of the femoral neck were of 9.7 KPa and 1.3 Kpa, and the minimum principal stress values obtained in the lower region of the femoral neck were of -8.7 KPa and -9.3 KPa. Finally, the peak values for Von Mises stress were of 7.2 GPa and 2.0 GPa for the fixation models with the use of the 3.5-mm cortical screw and the Herbert screw respectively. Conclusion The fixation system with the Herbert screw generated the best results in terms of reduction of vertical displacement, distribution of the maximum principal stress, and the peak Von Mises equivalent stress, demonstrating mechanical superiority compared to that of the 3.5-mm cortical screw in the treatment of Pipkin type-II fractures.

RESUMO

BACKGROUND: The prevalence of intertrochanteric hip fractures is approximately 30%. The usual management of hip fractures is performed by dynamic hip screw (DHS) or central medullary nailing (CMN). The COVID-19 pandemic has changed medical treatment guidelines in all specialties around the world. OBJECTIVE: To recognize the prevalence and management of unstable trochanteric hip fractures during the COVID-19 pandemic. METHOD: An observational study was conducted in a third-level care hospital in patients with fractures of type AOOTA 31A2.1 and A2.2 managed with CMN or DHS. The management trends by orthopedic surgeons were analyzed. RESULTS: The prevalence during 2019 was 38%, in 2020 it was 21.3% and in 2021 it was 32.6%. The male-to-female ratio found was 1:1.7. The age was 66.48 ± 21.6 years (range: 17-92). Of orthopedic surgeons surveyed, 80.4% preferred CMN. CONCLUSIONS: The prevalence decreased during 2020. The treatment trend during the pandemic was higher for the DHS system; the use of CMN decreased by 86%. The treatment of intertrochanteric hip fractures was influenced due to the COVID-19 pandemic towards a cheaper method.

ANTECEDENTES: La prevalencia de las fracturas transtrocantéricas se sitúa alrededor del 30%. El tratamiento se realiza mediante sistema de tornillo deslizante (STD) o clavo centromedular (CCM). La pandemia de COVID-19 ha modificado las pautas de tratamiento médico en todas las especialidades en todo el mundo. OBJETIVO: Reconocer la prevalencia y el manejo de las fracturas transtrocantéricas inestables durante la pandemia de COVID-19. MÉTODO: Se realizó un estudio observacional en un hospital de tercer nivel de atención en pacientes con fracturas de tipo AOOTA 31A2.1 y A2.2 manejados con CCM o STD, y se analizaron las tendencias de manejo por parte de los cirujanos ortopedistas. RESULTADOS: La prevalencia durante el año 2019 fue del 38%, en 2020 fue del 21.3% y en 2021 fue del 32.6%. La proporción encontrada hombre-mujer fue de 1:1.7. La edad fue de 66.48 ± 21.6 años (rango: 17-92). De los cirujanos ortopedistas encuestados, el 80.4% prefieren el CCM. CONCLUSIONES: La prevalencia disminuyó durante el año 2020. La tendencia de tratamiento durante la pandemia fue superior para el sistema STD y el uso de CCM disminuyó un 86%. El tratamiento de estas fracturas fue influenciado por la pandemia de COVID-19 hacia un método más económico.

RESUMO

Objective: Treatment modality is controversial in the unstable IT fractures. Ideal hemiarthroplasty treatment for unstable IT fractures should be comparable to that for FN fractures. Therefore, the aim of this study was to compare patients who underwent cementless hemiarthroplasty for a diagnosis of FN and unstable IT in terms of clinical outcomes, functional scores, and smartphone-based gait analysis data. Methods: Case matching was applied to 50 patients with FN fracture and 133 patients with IT fracture who underwent hemiarthroplasty treatment, they were compared in terms of, preoperative and postoperative walking status, and Harris hip scores. Smartphone-based gait analysis was applied to 12 patients in the IT group and 14 patients in the FN group who could walk without support. Results: There was no significant difference between patients with IT and FN fractures regarding Harris hip scores, preoperative, and postoperative walking status. In the gait analysis, gait velocity, cadence, step time, step length, and step time symmetry values were observed to be significantly better in patients in the FN group. Conclusion: Cementless hemiarthroplasty operations for unstable IT fractures have similar hip scores to FN fractures. However, the walking speed and walking symmetry data were seen to be worse. This result should be considered in the selection of appropriate treatment. Level of evidence III; Retrospective study.

Objetivo: O tratamento das fraturas instáveis da IT possui modalidades de tratamento com diferentes teorias. Hemiartroplastia é o tratamento ideal para fraturas instáveis (IT), devendo ser comparável à hemiartroplastia para fraturas do colo femoral (FN). Portanto, o objetivo deste estudo foi comparar pacientes que foram submetidos a hemiartroplastia não cimentada para diagnóstico do FN e IT instável em seus resultados clínicos, considerando a escala de estado funcional e a análise dos dados de habilidade de marcha coletadas por um smartphone. Métodos: A combinação de casos foi aplicada a 50 pacientes com fratura FN e 133 pacientes com fratura IT submetidos ao tratamento de hemiartroplastia, a habilidade de marcha pré e pós-operatório, incluindo suas pontuações Harris Hip, foram comparadas. A análise de marcha foi executada com smartphone em 12 pacientes do grupo IT e 14 pacientes do grupo CF, que conseguiam andar sem apoio. Resultados: Não foram encontradas diferenças significativas entre os pacientes com fraturas IT e FN em relação às pontuações Harris Hip nem quanto ao estado de marcha pré e pós-operatório. Na análise da marcha, os valores de velocidade, cadência, tempo de passo, comprimento do passo e simetria do tempo de passo foram significativamente melhores nos pacientes do grupo FN. Conclusão: As operações de hemiartroplastia não cimentada para fraturas instáveis de IT, têm pontuação de quadril semelhantes às fraturas FN. Entretanto, os dados de velocidade de caminhada e simetria de caminhada mostraram-se inferiores. Esses resultados devem ser considerados na escolha do tratamento adequado.Nível de evidência III; Estudo retrospectivo.

RESUMO

Objective: Evaluate the stability provided by two flexible intramedullary nails (FINs) in a simulation of fractures at the proximal levels in pediatric femur models. Methods: Two FINs were inserted in 18 synthetic models of pediatric femurs. Fractures were simulated at one of three levels, and the models were divided into the following groups (n=6): diaphysis (control), subtrochanteric and trochanteric. Flex-compression tests were performed with force up to 85 N. Relative stiffness and the average deformation was obtained. Torsion tests were performed by rotating the proximal fragment until 20°, to obtain the average torque. Results: At flex-compression, the set's average relative stiffness and average deformations were: 54.360x103 N/m and 1.645 mm in the control group, respectively. In the subtrochanteric group, the relative stiffness was 31.415x103 N/m (-42.2%) and the deformation was 2.424 mm (+47.3%) (p<0.05). For the trochanteric group, the relative stiffness was 30.912x103 N/m (+43.1%) and the deformation was 2.508 mm (+52.4%) (p<0.05). In torsion, the average torque was 1.410 Nm in the control group; 1.116 Nm in the subtrochanteric group (-20.8%), and 2.194 Nm in the trochanteric group (+55.6%) (p<0.05). Conclusion: FINs do not seem to be biomechanically competent for the treatment of proximal femoral fractures. Level of Evidence I; Therapeutic Studies - Investigating the results of treatment.
