ABSTRACT

Abstract 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.

ABSTRACT

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.

ABSTRACT

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

ABSTRACT

Abstract 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 1.5mm and 0.5mm. 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.

ABSTRACT

ABSTRACT 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 .

ABSTRACT

INTRODUCTION@#A significant treatment gap has been observed in patients with osteoporosis. Our previous audit found a 31.5% rate of anti-osteoporosis medication initiation after fragility fractures at one year. We piloted the use of telecarers to monitor osteoporosis treatment and compliance.@*METHODS@#From January 2017 to January 2018, all hip fracture patients at Changi General Hospital, Singapore, were automatically enrolled into the Health Management Unit valued care hip fracture programme. Telecarer calls were scheduled at discharge, 3, 6 and 12 months. We assessed the acceptability, completion and treatment rates of patients enrolled in this programme.@*RESULTS@#A total of 537 patients with a hip fracture were enrolled in the telecarer programme over one year. Their average age was 79.8 ± 8.23 years, and 63.1% of them were female. A total of 341 patients completed 12 months of follow-up, of which 251 (73.6%) patients were on treatment at 12 months. The most common cause of lack of initiation of secondary osteoporosis treatment was patient or family rejection (34.4%), followed by physician failure to prescribe (24.4%) and renal impairment (24.4%). 16.7% of patients were deemed to have advanced dementia with a life-limiting illness and were, thus, deemed unsuitable for treatment.@*CONCLUSION@#Telecarers may be a useful adjunct in the monitoring of osteoporosis treatment after hip fractures in an elderly population. The main limitations are patient or family rejection and physician inertia. Further studies should focus on a combination of interventions for both patients and physicians to increase awareness of secondary fracture prevention.

ABSTRACT

ABSTRACT Objective: Evaluating clinical factors associated with mortality in older patients who underwent surgical correction of hip fractures. Methods: This observational and retrospective study analyzed the medical records of 67 patients (aged older than 60 years), both men and women, who underwent surgical correction of hip fractures from 2019 to 2020 at Hospital São Paulo. The following variables were analyzed: age, sex, presence of comorbidities, affected hip region, and trauma mechanism. Statistical analyses were performed using the SPSS software. Results: The mean age of patients was 78.12 ± 9.80 years and 80.6% of the sample were women. The prevalence of hip fractures on the right side (52.2%), in the transtrochanteric region (53.7%), and due to fall on the same level (88.1%) was higher. Systemic arterial hypertension (77.6%), diabetes mellitus (37.3%), and dementia (16.4%) were frequent comorbidities. The prevalence of death after fracture was 17.9% and it was associated with longer hospital stay after surgery (p = 0.028). Conclusion: The prevalence of mortality of patients with hip fractures who underwent surgery was 17.9%. A longer hospital stay due to pre-existing comorbidities was the main factor related to this outcome. Level of Evidence III, Retrospective Study.


RESUMO Objetivo: Avaliar os fatores clínicos associados à mortalidade em pacientes idosos submetidos ao tratamento cirúrgico para correção de fraturas do quadril. Métodos: Estudo observacional e retrospectivo de análise de prontuários de 67 pacientes (idade superior a 60 anos). Foram incluídos indivíduos de ambos os sexos, submetidos ao tratamento cirúrgico para correção de fraturas do quadril, entre 2019 e 2020, no Hospital São Paulo. Foram analisadas as variáveis: idade, sexo, presença de comorbidades, região do quadril acometido e mecanismo de trauma. As análises estatísticas foram realizadas pelo software SPSS. Resultados: A idade média dos participantes foi de 78,12 ± 9,80 anos, e 80,6% da amostra era constituída por mulheres. Houve maior prevalência de fraturas do quadril no lado direito (52,2%), na região transtrocantérica (53,7%) e causada por queda sem desnível (88,1%). Hipertensão arterial sistêmica (77,6%), diabetes mellitus (37,3%) e demência (16,4%) foram frequentes. A prevalência de óbito após a fratura foi de 17,9%, sendo associada a maior tempo de internação hospitalar após a cirurgia (p = 0,028). Conclusão: A prevalência de mortalidade dos pacientes com fratura do quadril submetidos à cirurgia foi de 17,9%. O tempo prolongando de internação hospitalar por comorbidades pré-existentes foi o principal fator relacionado a este desfecho. Nível de Evidência III, Estudo Retrospectivo.

ABSTRACT

ABSTRACT 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.


RESUMO Objetivo avaliar a estabilidade proporcionada por duas hastes intramedulares flexíveis na simulação de fraturas nos níveis proximais em modelos pediátricos de fêmur. Métodos Duas hastes foram inseridas em 18 modelos sintéticos de fêmures pediátricos. As fraturas foram simuladas em um dos três níveis, e os modelos foram divididos nos seguintes grupos (n=6): diáfise(controle), subtrocantérico e trocantérico. Testes de flexão-compressão foram realizados com força de até 85N. A rigidez relativa e a deformação média foram obtidas. Os testes de torção foram realizados girando o fragmento proximal até 20°, para obter o torque médio. Resultados Na flexo-compressão, a rigidez relativa média e as deformações médias do conjunto foram: 54,360x103 N/m e 1,645 mm no grupo controle, respectivamente. No grupo subtrocantérico a rigidez relativa foi de 31,415x103 N/m (-42,2%) e a deformação foi de 2,424 mm (+47,3%) (p<0,05). Para o grupo trocantérico a rigidez relativa foi de 30,912x103 N/m (+43,1%) e a deformação foi de 2,508 mm (+52,4%) (p<0,05). Na torção, o torque médio foi de 1.410 Nm no grupo controle; 1,116 Nm no grupo subtrocantérico (-20,8%) e 2,194 Nm no grupo trocantérico (+55,6%) (p<0,05). Conclusão As hastes intramedulares flexíveis não parecem ser biomecanicamente competentes para o tratamento das fraturas proximais do fêmur.

ABSTRACT

ABSTRACT 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.


RESUMO 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.

ABSTRACT

Abstract 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.

ABSTRACT

Introdução: Em 2020 teve início a pandemia de COVID-19 e considerando que para combatê-la houve recomendações de isolamentos sociais - permanência em suas residências - esperava-se que ocorresse grande quantidade de pessoas expostas às fraturas transtrocantéricas, principalmente os idosos. Objetivo: Avaliar a ocorrência dessas fraturas durante o período de pandemia COVID-19. Métodos: Estudo retrospectivo, transversal e observacional, com abordagem quantitativa. O levantamento de dados foi realizado por meio da análise de prontuários eletrônicos de pacientes durante o período de março de 2020 a outubro de 2021. As variáveis analisadas foram: idade, sexo, mecanismo de trauma, lado da fratura, comorbidades associadas, tempo entre a entrada e a operação, tipo de implante, tempo de hospitalização e fraturas associadas. Resultados: A amostra foi composta por 182 pacientes, sendo 61 homens e 121 mulheres, idade variando de 24-98 anos. O mecanismo de queda do mesmo nível foi responsável por 160 dos casos e não houve predominância de lado da fratura. As principais comorbidades foram a hipertensão e diabete melito; 92 pacientes foram operados em até 48 h de admissão. Implante cefalomedular foi usado em 159 casos. Ocorreram 19 óbitos intra-hospitalares dos quais 10 tinham fraturas associadas. Conclusão: Foi possível observar predominância do sexo feminino e idosos e elevação da idade média. O mecanismo de queda do mesmo nível foi responsável por 87% dos casos e não houve predominância de lado na fratura.


Introduction: In 2020, the COVID-19 pandemic began and considering to combat there were recommendations for social isolation - staying in their homes - what expected a large number of people would be exposed to transtrochanteric fractures, especially the elderly. Objective: To evaluate the occurrence of these fractures during the period of the COVID-19 pandemic. Methods: Retrospective, cross-sectional and observational study with a quantitative approach. Data collection was carried out through the analysis of electronic medical records of patients during the period from March 2020 to October 2021. The variables analyzed were: age, gender, trauma mechanism, fracture side, associated comorbidities, time between entry and operation, type of implant, length of hospital stay and associated fractures. Results: The sample consisted of 182 patients, 61 men and 121 women, ages ranging from 24-98 years. The mechanism of falling from the same level was responsible for 160 of the cases and there was no predominance of the side of the fracture. The main comorbidities were hypertension and diabetes mellitus; 92 patients were operated within 48 h of admission. Cephalomedullary nail ( was used in 159 cases. There were 19 in-hospital deaths, of which 10 had associated fractures. Conclusion: It was possible to observe a predominance of females and the elderly and an increase in the average age. The mechanism of falling from the same level was responsible for 87% of the cases and there was no predominance of the side in the fracture.

ABSTRACT

Introducción: La fractura de cadera (FC) es una solución de continuidad en el extremo proximal del fémur, con consecuencias significativas para quien la padece. Este estudio busca comparar descriptivamente la tasa de mortalidad por FC en el periodo 2017-2022, en Chile. Metodología: Estudio descriptivo observacional sobre defunciones por FC entre 2017 y 2022, en Chile (n= 3.190), según datos del Departamento de Estadísticas e Información de Salud de Chile. Se calcularon tasas de mortalidad por FC por variable, índice de sobremortalidad e índice de Swaroop, utilizando datos del Censo 2017. No requirió comité de ética. Resultados: La mayor tasa de mortalidad por FC se observó en el año 2018 (3,23), en el grupo de 100 años y más (2.264,15), la región de Valparaíso (28,31) y el sexo femenino (4,32) reflejandose en su índice de sobremortalidad (2,589). La menor tasa de mortalidad por FC ocurrió en el año 2021 (2,76), en el grupo de entre 0 y 19 años (0,04) y en la región de Atacama (12,58). El índice de Swaroop fue 100% en la mayoría de las regiones. Discusión: La tendencia a la baja desde el año 2019 podría explicarse por el confinamiento por COVID-19 que limitó la movilidad de las personas mayores. Los cambios postmenopausicos y un mayor riesgo de caídas podrían explicar una mayor tasa de mortalidad por FC en mujeres y pacientes de edad avanzada, respectivamente. El análisis por región podría relacionarse con la proporción demográfica de personas mayores.


Introduction: The hip fracture (HF) is a discontinuity in the proximal end of the femur, with significant consequences for those who suffer from it. This study aims to descriptively compare the HF mortality rate in the period 2017-2022 in Chile. Methodology: This is an observational descriptive study on deaths due to HF between 2017 and 2022 in Chile (n=3,190), according to data from the Department of Statistics and Health Information of Chile. HF mortality was calculated by variable, excess mortality rate, and Swaroop index, using data from the 2017 Census. No ethics committee was required. Results: The highest HF mortality rate was in 2018 (3,23), in the age group of 100 years and older (2.264,15), the Valparaíso region (28,31) and the female sex (4,32) reflected in its excess mortality rate (2,589). The lowest HF mortality rate occurred in 2021 (2,76), in the group between 0 and 19 years (0,04) and in the Atacama region (12,58). The Swaroop index was 100% in most regions. Discussion: The downward trend since 2019 could be explained by the COVID-19 lockdown that limited the mobility of elderly adults. Postmenopausal changes and a higher risk of falls could explain higher HF mortality rate in women and old people patients, respectively. The regional analysis could be related to the demographic proportion of elder people.

ABSTRACT

Objective:To compare the analgesic effect and postoperative recovery between multi-point and single-point ultrasound-guided fascia iliaca compartment block (FCIB) in elderly patients with hip fracture.Methods:From June 2019 to April 2020, 96 patients aged (71.1±5.4) years undergoing elective surgery for hip fracture in Renji Hospital were randomly assigned in multi-point block group or single-point block group, and the multi-point or single-point ultrasound-guided FCIB was performed for the two groups, respectively. The primary outcomes were the success rate for block of femoral nerve, lateral femoral cutaneous nerve and obturator nerve, and the 24 hours postoperative pain visual analog scale (VAS) score at rest and passive movement. The secondary outcomes were the onset time of sensory blocks of the above three nerves, complications of FICB, the satisfaction score of pain control during 48 hours after surgery and postoperative recovery of patients.Results:The success rate for block of lateral femoral cutaneous nerve in multi-point block group was 97.9% (47/48), which was significantly higher than that in single-point block group (83.3%(40/48)) ( P=0.031). The success rate for block of obturator nerve in multi-point block group was 95.8% (46/48), which was significantly higher than that in single-point block group which was 81.3% (39/48) ( P=0.025). The success rate of femoral nerve block in both groups was 97.9% (47/48) ( P=1.000). The 24 hours postoperative VAS scores at rest and passive movement in the multi-point block group were significantly lower than those in the single-point block group ( P<0.05). The onset time for block of lateral femoral cutaneous nerve and obturator nerve in multi-point block group was shorter than that in single-point block group ( P=0.025 and P<0.01). There was no significant difference in the onset time for block of femoral nerve between the two groups ( P=0.343). The satisfaction score of patients at 48 hours after surgery in multipoint block group was higher than that in single point block group ( P=0.024). The length of hospital stay in the multi-point block group was shorter than that in the single-point block group ( P=0.042), the proportion of intravenous analgesic drugs used after surgery was lower than that in the single-point block group ( P=0.041), and the complication rate within 30 days after surgery was also lower than that in the single point block group ( P=0.026). Conclusion:Compared with single-point block, ultrasound-guided multi-point block in iliac fascia space has advantages of increasing analgesic efficacy and promoting postoperative recovery in elderly patients with hip fracture.

ABSTRACT

Objective:To study the risk factors of acute stroke within 1 year after hip fracture in the elderly and its effect on prognosis.Methods:From January 2018 to December 2020, 278 elderly hip fracture patients undergoing surgery were retrospectively analyzed, including 101 males and 177 females, aged from 60 to 99 years with an average of(78.9±8.7)years.According to whether acute stroke occurred within 1 year after operation, the patients were divided into stroke group and non-stroke group.A multivariate Logistic regression was used to evaluate the risk factors for acute stroke within 1 year after hip fracture, and the prognosis was analyzed.Results:Acute stroke occurred in 28 patients(10.1%)within 1 year after operation, and the peak of stroke onset occurred in the third months after operation.Patients in the stroke group were older, and had a higher proportion of hypertension, arrhythmia, previous stroke history, and use of anticoagulant or antiplatelet drugs before fracture( P<0.05 for all). Multivariate Logistic regression analysis showed that advanced age( OR=1.078, 95% CI=1.007-1.153, P=0.030), male( OR=2.643, 95% CI=1.060-6.742, P=0.037)and previous stroke history( OR=12.202, 95% CI=4.662-31.940, P<0.001)were independent risk factors for stroke in elderly patients with hip fracture within 1 year after operation.The 1-year mortality, complication rate and readmission rate in the stroke group were significantly higher than those in the non-stroke group( P<0.05 for all). Conclusions:The incidence of stroke is high in elderly patients with hip fracture within 1 year after operation.Older age, male, and previous stroke history were independent risk factors for acute stroke.The prognosis of stroke was poor in elderly patients with hip fracture, and the 1-year mortality, complication and readmission rates were high.

ABSTRACT

Objective:To study the relationship between red blood cell distribution width(RDW)and short-term mortality in elderly patients with hip fragility fractures.Methods:The clinical data and blood routine test at admission of 205 elderly patients with brittle hip fractures who were admitted to our hospital from 2020 to 2021 and were followed up for one year were retrospectively analyzed.The comorbid conditions, RDW and cumulative mortality at 6 months and 1 year after fractures were counted, and the relationship between RDW and short-term mortality were analyzed.Results:The 6-month(6.7% and 20.8%, χ2=8.591, P=0.003)and 1-year(6.7% and 26.7%, χ2=14.818, P<0.001)mortality of patients with ≤1 comorbidity were significantly lower than those of patients with ≥2 comorbidities.Moreover, the 6-month and 1-year mortality in patients with RDW>13.5% were significantly higher than those of patients with RDW ≤ 13.5%.The proportion of RDW>13.5 % in patients with at least two comorbidities was significantly higher than that in patients with ≤1 comorbidity.Taking RDW=13.6% as the cut-off value of 6-month and 1-year mortality, the sensitivity and specificity for predicting 6-month mortality were 71.4 % and 59.9 %, respectively, and the sensitivity and specificity for predicting 1-year mortality were 64.7 % and 59.6 %, respectively. Conclusions:Red cell distribution width is associated with short-term mortality, and higher RDW is associated with a higher risk of mortality among elderly patients with brittle hip fractures.

ABSTRACT

Objective:To analyze the risk factors of acute kidney injury (AKI) in hip fracture patients with serious underlying diseases and establish a prediction nomogram.Methods:Clinical information of hip fracture patients admitted to the intensive care unit (ICU) of Beth Israel Deaconess Medical Center (BIDMC) was analyzed using the Medical Information Mart for Intensive Care (MIMIC)-IV. Patient comorbidities, disease scores, vital signs and laboratory tests, surgical modalities, invasive procedures, and drug use were recorded. According to the diagnostic criteria of AKI in the Kidney Disease Improving Global Outcome (KDIGO) guideline, the enrolled patients were randomly divided into training set and validation set. Based on logistic regression analysis, least absolute shrinkage and selection operator (LASSO) logistic regression algorithm was used to analyze the risk factors of AKI after admission, and the corresponding prediction model was calculated.Results:A total of 474 patients were enrolled, including 331 in the training set and 143 in the validation set. According to the diagnostic criteria of AKI of KDIGO guidelines, the patients were divided into AKI group (159 cases) and non-AKI group (172 cases). Univariate analysis showed that age ( t=2.61, P=0.009), coronary heart disease (χ 2=2.08, P=0.038), heart failure (χ 2=2.60, P=0.009), hemoglobin ( t=1.89, P=0.059), platelets ( t=1.81, P=0.070), urea nitrogen ( t=2.83, P=0.005), blood creatinine ( t=3.65, P<0.001), blood sodium ( t=2.55, P=0.011), blood glucose ( t=2.52, P=0.012), anion gap ( t=3.44, P=0.001), diastolic blood pressure ( t=2.72, P=0.007), mean arterial pressure ( t=2.16, P=0.031), SOFA score ( t=3.69, P<0.001), simplified acute physiological function score II (SAPSII) score ( t=2.95, P=0.003), as well as furosemide (χ 2=2.03, P=0.042), vancomycin (χ 2=1.70, P=0.089), vasoactive medications (χ 2=3.74, P<0.001) and use of invasive mechanical ventilation (χ 2=4.81, P<0.001) were risk factors associated with the development of AKI in hip fracture patients. Multivariate logistic regression analysis showed that age ( OR=1.03, P<0.001), coronary heart disease ( OR=2.05, P=0.069), hemoglobin ( OR=0.88, P=0.050), blood creatinine ( OR=1.37, P=0.009), blood sodium ( OR=1.07, P=0.026), anion gap ( OR=1.09, P=0.028) and vasoactive medications ( OR=3.83, P=0.018) and the use of invasive mechanical ventilation ( OR=6.56, P<0.001) were independent predictors of the development of AKI in hip fracture patients with serious underlying diseases. The area under the curve of the nomogram prediction model constructed by the above 8 predictors was 0.789, and the calibration curve of the nomogram was close to the ideal diagonal. Decision curve analysis showed that the net benefit of the model was significant. Conclusion:The incidence of AKI is high in hip fracture patients with serious underlying diseases. Age, coronary heart disease, hemoglobin, serum creatinine, serum sodium, anion gap, vasoactive drugs, and invasive mechanical ventilation can predict the occurrence of AKI to a certain extent. Combined with the risk factors, the construction of the corresponding prediction model can predict and manage the diagnosis and treatment of AKI in patients with hip fracture complicated with severe underlying diseases.

ABSTRACT

Objective:To establish a risk assessment system focusing on surgical and anesthesian-related indicators for the incidence of complications and mortality of hip fracture surgery in senile patients, and to evaluate its prediction accuracy, sensitivity and specificity.Methods:From January 2020 to February 2021, a total of 1 086 elderly patients (493 males and 593 females) aged 76±5 years (ranging from 60 to 94 years) underwent hip fracture surgery in Tianjin Hospital were collected. A total of 543 patients were randomly selected for the establishment of the hip fracture scoring system in senile patients, including 253 males and 290 females, aged 75±6 years (ranging from 60 to 92 years). With the preoperative physiological factor score and surgical risk factor score as independent variables and the occurrence of complications and death as dependent variables, binary logistic regression analysis was performed to establish a surgical risk scoring system for hip fracture in senile patients. The remaining 543 patients, including 240 males and 303 females, aged 74±7 years (range 60-94 years), their data were used to compare AUC, sensitivity, specificity, and compliance of the physiological and operative severity score for the enumeration of mortality and morbidity (POSSUM), Daping orthopedics operative risk scoring system for senile patient (DORSSSP), and our surgical risk scoring system for hip fracture in senile patients through receiver operating characteristic (ROC) curves, and to compare the predictive value of these systems for complication incidence and mortality.Results:The predictive model equation of the elderly hip fracture scoring system is: ln R1/ (1- R1) =-7.13+0.112× PS+0.148× OS; ln R2/ (1- R2) =-6.14+0.124× PS+0.136× OS; [ R1 is the incidence of complications, R2 is the mortality, PS (physiology score) is the score of preoperative physiological factors, and OS (operation score) is the score of surgical risk factors]. Among the 543 patients whose data were used to compared with the hip fracture scoring system, POSSUM and DORSSSP, 72 actually developed complications and 36 died. The complication rate predicted by surgical risk scoring system for hip fracture in senile patients was 12.05%±6.34% (range 6.18%-61.29%), and 64 cases were predicted to have complications. The predicted mortality was 6.05%±3.26% (range 2.45%-58.36%), and 29 cases were predicted to die. The complication rate predicted by POSSUM was 25.36%±13.95% (range 9.16%-76.34%), and 126 cases were predicted to have complications. The predicted mortality rate was 10.46%±5.31% (range 6.23%-59.34%), and 54 deaths were predicted. The predicted complication rate of DORSSSP was 19.34%±9.67% (range 8.36%-70.85%), and 99 cases were predicted to have complications. The predicted mortality was 10.12%±5.16% (range 7.35%-57.54%), and 52 deaths were predicted. In predicting the incidence of complications, the AUC of surgical risk scoring system for hip fracture in senile patients, POSSUM and DORSSSP were 0.95, 0.82 and 0.75, the sensitivity was 0.89, 0.83 and 0.85, the specificity was 0.80, 0.86 and 0.92, and the compliance rate was 0.94, 0.93 and 0.94, respectively. In the prediction of mortality, the AUC of surgical risk scoring system for hip fracture in senile patients, POSSUM and DORSSSP were 0.87, 0.67 and 0.71, the sensitivity was 0.85, 0.69 and 0.75, the specificity was 0.73, 0.94, 0.95, and the compliance rate was 0.94, 0.93 and 0.94, respectively. Conclusion:Compared with POSSUM and DORSSSP, hip fracture scoring system in elderly patients has improved its ability to predict surgical risk, and can accurately predict the incidence of complications and mortality in elderly patients undergoing hip surgery.

ABSTRACT

Objective:To compare the short-term effects of proximal femoral bionic nail (PFBN) and proximal femoral nail antirotation (PFNA) in the treatment of intertrochanteric fracture.Methods:Retrospectively analyzed were the data of 56 patients with intertrochanteric fracture of the femur who had been admitted to Department of Orthopedic Trauma, The People's Hospital of Juye County and Trauma Center, Central Hospital Affiliated to The First Medical University of Shandong from August 2020 to April 2022. The patients were divided into 2 even groups according to their internal fixation methods ( n=28). In the PFBN fixation group, there were 12 males and 16 females with an age of (70.4±7.8) years; by AO classification, there were 4 cases of type 31-A1, 16 cases of type 31-A2, and 8 cases of type 31-A3. In the PFNA fixation group, there were 10 males and 18 females with an age of (73.0±8.9) years; by AO classification, there were 2 cases of type 31-A1, 16 cases of type 31-A2, and 10 cases of type 31-A3. The operation time, intraoperative blood loss, fracture reduction, fracture healing time, Harris hip score, and complications were compared between the 2 groups. Results:There was no statistically significant difference between the 2 groups in the preoperative general data, showing comparability ( P>0.05). The follow-up time was (7.3±0.9) months for the PFBN group and (7.4±1.1) months for the PFNA group, showing no significant difference ( P>0.05). There was no significant difference either between the 2 groups in operation time, intraoperative blood loss or quality of fracture reduction ( P>0.05). The PFNA group had significantly shorter fracture healing time [(3.9±0.9) months] than the PFNA group [(4.7±1.1) months], and a significantly higher Harris hip score at the last follow-up [(83.9±4.3) points] than the PFNA group [(81.0±3.4) points] (both P<0.05). Fixation failed in one patient in the PFNA group due to cut-out of the head and neck screws while no complications were observed in the PFBN group. Conclusion:In the treatment of intertrochanteric fracture of the femur, PFBN fixation may result in stronger fixation to effectively avoid cut-out of the head and neck screws, and faster fracture healing and functional recovery of the hip than PFNA fixation.
