Clinical and subclinical arteriosclerotic disease in octagenarians with hip fracture. A case-control study.

BACKGROUND AND OBJECTIVES: Evaluate clinical and subclinical arteriosclerotic disease in older patients with hip fracture compared with patients without fracture in order to increase knowledge about the relation between both diseases in older individuals. PATIENTS AND METHODS: Age- and sex-matched case-control study of octogenarians with and without recent hip fracture. Vascular risk factors, subclinical vascular diseases (assessed by carotid plaques, carotid intima media thickness and arterial stiffness) as well as cardiovascular diseases were analyzed. Univariate and multivariate logistic models were used to estimate odds ratios (OR) with their 95% confidence intervals (CI) to assess the association of the arteriosclerosis and hip fracture. RESULTS: We analyzed 95 patients per group with a median age of 82 [79-87] years of whom 77.9% were female. Patients in both groups have elevated rates of vascular disease (25%) without differences between them. Patients with hip fracture had higher subclinical arteriosclerotic alterations with higher percentage of carotid plaques (OR 3.25 [1.06-9.97]) compared with the control group. CONCLUSIONS: Older patients with hip fracture had significantly higher presence of subclinical alterations but not increase on rate of cardiovascular arteriosclerotic disease compared with those without hip fracture.

Concurrent uper limb and hip fracture in the elderly: experience at our centre. / Fracturas concomitantes de miembro superior y cadera en pacientes mayores de 65 años: experiencia en nuestro centro.

INTRODUCTION: The incidence of hip fracture in the elderly is on the rise, occasionally accompanied by concurrent upper limb fractures. Our investigation aims to determine whether these patients experience poorer functional outcomes, prolonged hospitalization, or higher mortality rates when compared to those with isolated hip fracture. MATERIAL AND METHODS: We retrospectively reviewed 1,088 elderly patients admitted to our centre with hip fracture between January 2017 and March 2020. We recorded the presence of concomitant fractures and their treatment. We analyzed the duration of hospital stay, in-hospital mortality and function. RESULTS: We identified 63 patients with concomitant upper limb fracture (5.6%). Among them, 93.7% were women, and the average age was 86.4 years. 80.9% of the upper limb fractures were distal radius or proximal humerus. Patients with concomitant fracture had increased length of stay (mean, 19.6 vs, 12.8, p=0.002), decreased proportion of patients returning to their own home at discharge (23.6% vs, 26.3%, p=0.042) and increased in-hospital mortality rate (9.5% vs, 5.9%, p=0.003). CONCLUSIONS: Patients with concomitant upper limb fracture require a longer length of stay and exhibit an elevated in-hospital mortality rate. Furthermore, this condition is associated with a reduced short-term functional recovery, thereby decreasing the chances of the patient returning home upon hospital discharge.

Analysis of machine learning algorithmic models for the prediction of vital status at six months after hip fracture in patients older than 74 years. / Análisis de modelos algorítmicos de aprendizaje automático para la predicción del estado vital a los seis meses tras fractura de cadera en pacientes mayores de 74 años.

BACKGROUND AND OBJECTIVE: The objective is to develop a model that predicts vital status six months after fracture as accurately as possible. For this purpose we will use five different data sources obtained through the National Hip Fracture Registry, the Health Management Unit and the Economic Management Department. MATERIAL AND METHODS: The study population is a cohort of patients over 74 years of age who suffered a hip fracture between May 2020 and December 2022. A warehouse is created from five different data sources with the necessary variables. An analysis of missing values and outliers as well as unbalanced classes of the target variable («vital status¼) is performed. Fourteen different algorithmic models are trained with the training. The model with the best performance is selected and a fine tuning is performed. Finally, the performance of the selected model is analyzed with test data. RESULTS: A data warehouse is created with 502 patients and 144 variables. The best performing model is Linear Regression. Sixteen of the 24 cases of deceased patients are classified as live, and 14 live patients are classified as deceased. A sensitivity of 31%, an accuracy of 34% and an area under the curve of 0.65 is achieved. CONCLUSIONS: We have not been able to generate a model for the prediction of six-month survival in the current cohort. However, we believe that the method used for the generation of algorithms based on machine learning can serve as a reference for future works.

Evaluación de la intervención de fisioterapia en los pacientes con sarcopenia y fractura de cadera: una revisión sistemática / Evaluation of physiotherapy intervention in patients with sarcopenia and hip fracture: A systematic review

Introducción La sarcopenia en los pacientes con fractura de cadera es cada vez más habitual en la población envejecida, aumentando el riesgo de hospitalización, dependencia y mortalidad. Objetivos Valorar el tratamiento de fisioterapia más efectivo en los pacientes con sarcopenia y fractura de cadera a través de la revisión de evidencia sistemática. Métodos Se realizó una búsqueda entre febrero y mayo de 2022 en 8 bases de datos electrónicas (Pubmed, Scopus, PEDro, Web of Science, Cochrane, Google Scholar y Springer Link), con el fin de extraer ensayos clínicos publicados en los últimos 12 años en español e inglés. Resultados Se seleccionaron 3 ensayos clínicos que cumplían los criterios de inclusión. En todos ellos las intervenciones de fisioterapia incluían ejercicio aeróbico, de fuerza, de alta intensidad, de movilizaciones y combinados. La calidad metodológica se evaluó con la escala PEDro (puntuación media entre 6 y 10). Uno de los estudios no encuentra diferencias entre el tratamiento estándar y el grupo que recibe además entrenamiento progresivo de fuerza muscular. Otro constata una mejora a corto plazo en el grupo que recibe además del tratamiento convencional entrenamiento en cinta rodante con soporte del peso corporal durante el ejercicio con seguimiento a los 3 y 6 meses. El estudio que suplementa con aminoácidos esenciales es el único que constata una mejoría en los pacientes con sarcopenia. Conclusión Los pacientes con sarcopenia y fractura de cadera, pueden tener una mejor evolución si combinan ejercicios de fisioterapia con un protocolo nutricional. Son necesarias más investigaciones metodológicamente rigurosas sobre este tema para poder ampliar la evidencia. (AU)

Introduction Sarcopenia in patients with hip fracture is increasingly common in the elderly population, increasing the risk of hospitalization, dependency, and mortality. Objectives To assess the most effective physiotherapy treatment in patients with sarcopenia and hip fracture through systematic evidence review. Methods Electronic databases were searched from February to May 2022 using Pubmed, Scopus, PEDro, Web of Science, Cochrane, Google Scholar, and Springer Link in order to extract randomized clinical trials published in full text both English and Spanish for the last 12 years. Results Three clinical trials that met the inclusion criteria were selected. In all of them, the physiotherapy interventions included aerobic, strength, high intensity, mobilization, and combined exercises. Methodological quality was assessed using the PEDro scale (average score between 6 and 10). One of the studies found no differences between the standard treatment and the group that also received progressive muscle strength training. Another found a short-term improvement in the group that received, in addition to conventional treatment, treadmill training with body weight support during exercise with follow-up that was not maintained at three and six months. The study that supplements with essential amino acids is the only one that confirms an improvement in patients with sarcopenia. Conclusion Patients with sarcopenia and hip fracture may have a better evolution if they combine physiotherapy exercises with a nutritional protocol. More methodologically rigorous research on this topic is needed to expand the evidence. (AU)

Objetivo Este estudio tiene como objetivo identificar los factores de riesgo asociados con las fracturas de cadera osteoporóticas en octogenarios y busca perfeccionar las estrategias de prevención primaria para estas fracturas. Material y métodos Realizamos un estudio de casos y controles en el que participaron personas de 79 años o más con fracturas de cadera, comparándolas con controles de la misma edad y sexo sin antecedentes de fracturas de cadera. Se recogieron factores epidemiológicos, clínicos, antropométricos y analíticos. Se evaluó la presencia de osteoporosis mediante densitometría ósea. Definimos la sarcopenia según los criterios del Grupo de Trabajo Europeo sobre Sarcopenia en Personas Mayores (EWGSOP2). Resultados Se analizaron 95 pacientes por grupo, con una edad media de 82 años, de los cuales 74% eran mujeres. El análisis multivariado incluyó factores estadísticamente significativos encontrados en el análisis univariado (p<0,05). Estos factores incluyeron el índice de Barthel, la evaluación nutricional mediante la herramienta CONUT, el ácido fólico, la deficiencia de vitamina D, la presencia de fracturas previas, la pérdida de agudeza visual, la circunferencia bicipital, la sarcopenia y la osteoporosis (densitometría en el cuello del fémur). El estado nutricional (OR: 0,08 [0,01-0,61]), los niveles de ácido fólico (OR 0,32 [0,1-1]) y la pérdida de agudeza visual (OR 33,16 [2,91-377,87]) fueron los factores de riesgo independientes asociados con fractura de cadera. Conclusiones La evaluación del estado nutricional en pacientes de edad avanzada, junto con una evaluación geriátrica integral, representan herramientas fácilmente reproducibles y rentables. Estas herramientas pueden ayudar eficazmente a identificar a las personas con riesgo de sufrir fracturas de cadera, contribuyendo así a medidas preventivas más específicas y eficientes. (AU)

Objective This study aims to identify the risk factors associated with osteoporotic hip fractures in octogenarians and seeks to refine primary prevention strategies for these fractures. Material and methods We conducted a case–control study involving individuals aged 79 years and older with hip fractures, comparing them to age- and sex-matched controls without a history of hip fractures. We collected epidemiological, clinical, anthropometric, and analytical factors. We evaluated the presence of osteoporosis using bone densitometry. We defined sarcopenia according the European Working Group on Sarcopenia in Older People criteria (EWGSOP2). Results Ninety-five patients per group were analyzed, with a mean age of 82 years, of which 74% were women. The multivariate analysis included statistically significant factors found in the univariate analysis (P<.05). These factors included the Barthel Index, nutritional assessment using the CONUT tool, folic acid, vitamin D deficiency, presence of previous fractures, loss of visual acuity, bicipital circumference, sarcopenia, and osteoporosis (densitometry in the neck of the femur). The nutritional state (OR: 0.08 [0.01–0.61]), the folic acid levels (OR 0.32 [0.1–1]), and a loss of visual acuity (OR 33.16 [2.91–377.87]) were the independent risk factors associated with hip fracture. Conclusions The assessment of nutritional status in elderly patients, coupled with a comprehensive geriatric assessment, represents easily reproducible and cost-effective tools. These tools can effectively aid in identifying individuals at risk of hip fractures, thereby contributing to more targeted and efficient preventive measures. (AU)

Short versus long intramedullary nails for intertrochanteric hip fracture: Meta-analysis. / [Artículo traducido] Clavo corto versus clavo largo en la fractura intertrocantérica de cadera: metaanálisis.

OBJECTIVE: To compare short versus long intramedullary nails for intertrochanteric hip fractures in terms of efficacy and safety. METHODS: We included cohort studies and randomized clinical trials. The methodological quality of the studies was assessed by the Newcastle-Ottawa Scale. The meta-analysis was performed using the Review Manager 5.4. Heterogeneity was checked with the I2 test. A fixed effects model was adopted if there was no heterogeneity. RESULTS: Twelve studies were included. The reoperations rate was lower in the short nail group (OR: 0.58, 95%CI: 0.38-0.88) and there were no differences regarding the peri-implant fracture rate (OR: 1.77, 95%CI: 0.68-4.60). Surgery time and blood loss was significantly higher in the long nail group (MD: -12.44, 95%CI: -14.60 -10.28) (MD: -19.36, 95%CI: -27.24 -11.48). There were no differences in functional outcomes. CONCLUSIONS: The long nail showed a higher reoperation rate, blood loss and surgery time compared to the short nail. LEVEL OF EVIDENCE: III.

Currently, the true prevalence of this syndrome is unknown as its detection and management are not standardized in clinical practice. METHODS: A multicenter observational cross-sectional study will be conducted nationwide, involving different orthogeriatric units in Spain. The prevalence of delirium will be assessed using the 4AT scale, along with its characteristics and its relationship with other geriatric syndromes, sociodemographic variables, surgical characteristics, and laboratory parameters. RESULTS: Data collection is scheduled to take place on World Delirium Day (Wednesday, March 13, 2024), and therefore, the results are expected during the second or third quarter of 2024. CONCLUSIONS: Understanding the real prevalence and characteristics of delirium in older adults with HF could contribute to the development of strategies for its detection and management, reducing the impact of its consequences.

Demographic, functional and clinical characteristics in hip fracture patients according to mental status of the Spanish National Hip Fracture Registry.

OBJECTIVE: To describe the differences according to mental status at admission on the care process and 30-day outcomes in hip fracture patients, mainly regarding the use of rehabilitation resources and anti-osteoporotic medication, by analysing data from the Spanish National Hip Fracture Registry (RNFC, "Registro Nacional de Fracturas de Cadera" in Spanish). METHODS: We analysed prospectively collected data from a cohort of patients admitted participating in the Spanish National Hip Fracture Registry (RNFC) in 76 Spanish hospitals between 2017 and 2019. We classified participants using Short Portable Mental Status Questionnaire (SPMSQ), defining two groups: patients with ≤2 SPMSQ score and patients with >2 SPMSQ score. RESULTS: Of 21,254 patients was recorded SPMSQ in 17,242 patients, 9052 were >2 SPMSQ score (52.6%). These were older (87.7 vs. 85.3 years; p<0.001), had worse mobility (no-independent walking ability 26.0% vs. 4.5%; p<0.001) and were more likely to be living in nursing homes (35.3% vs. 9.6%; p<0.001). They were more likely to be treated nonoperatively (3.8% vs. 1.5%; p>0.001), less early mobilisation (57.5% vs. 68.9%; p<0.001) and suffered higher in-hospital mortality (5.2% vs. 2.7%; p<0.001). At discharge, they received less anti-osteoporotic medication (37.9% vs. 48.9%; p<0.001) and returned home less often (29.8%% vs. 51.2%; p<0.001). One month after fracture, patients with >2 SPMSQ score had poorer mobility (no-independent walking ability 44.4% vs. 24.9%; p<0.001) and were newly institutionalised in a nursing home more (12.6% vs. 12.0%; p<0.001) and were more likely to die by one-month post-fracture (9.5% vs. 4.6%; p<0.001). CONCLUSION: RNFC patients with >2 SPMSQ score were more vulnerable and had poorer outcomes than patients with ≤2 SPMSQ score, suggesting that they need specialised care in-hospital and in the recovery phase.

[Clinical and radiographic factors associated with failure of the dynamic hip screw system]. / Factores clínicos y radiográficos asociados a la falla del sistema del tornillo dinámico de cadera.

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.

Menor mortalidad y reingreso en pacientes con pocas comorbilidades intervenidos de fractura de cadera y con alta precoz / Lower mortality and readmission in patients with few comorbidities who underwent hip fracture surgery and were discharged early

Introducción: El retraso preoperatorio en pacientes intervenidos de fractura de cadera (FC) se ha asociado a peores resultados; sin embargo, el momento óptimo del alta hospitalaria tras cirugía ha sido poco estudiado. El objetivo de este estudio fue determinar resultados de mortalidad y de reingreso en pacientes con FC con y sin alta hospitalaria precoz. Material y métodos: Se realizó un estudio observacional retrospectivo seleccionando a 607 pacientes mayores de 65años con FC intervenidos entre enero de 2015 y diciembre de 2019, de los que se incluyeron para el análisis 164 pacientes con menos comorbilidades y ASA ≤II y se dividieron según su estancia hospitalaria postoperatoria en alta precoz o estancia ≤4días (n=115) y alta no precoz o estancia postoperatoria >4días (n=49). Se registraron características demográficas; características relacionadas con la fractura y el tratamiento quirúrgico; tasas de mortalidad a los 30días y al año postoperatorio; tasa de reingreso hospitalario a los 30días postoperatorios, y causa médica o quirúrgica. Resultados: En el grupo alta precoz todos los resultados fueron mejores frente al grupo no alta precoz: menor tasa de mortalidad a los 30días postoperatorios (0,9% frente al 4,1%, p=0,16) y al año postoperatorio (4,3% frente al 16,3%, p=0,009), así como una menor tasa de reingreso hospitalario por razones médicas (7,8% frente al 16,3%, p=0,037). Conclusiones: En el presente estudio el grupo de alta precoz obtiene mejores resultados en indicadores de mortalidad a los 30días y al año postoperatorio, así como de reingreso por causas médicas.(AU)

Introduction: Preoperative delay in patients with hip fracture surgery (HF) has been associated with poorer outcomes; however, the optimal timing of discharge from hospital after surgery has been little studied. The aim of this study was to determine mortality and readmission outcomes in HF patients with and without early hospital discharge. Material and methods: A retrospective observational study was conducted selecting 607 patients over 65years of age with HF intervened between January 2015 and December 2019, from which 164 patients with fewer comorbidities and ASA ≤II were included for analysis and divided according to their postoperative hospital stay into early discharge or stay ≤4 days (n=115), and non-early or post-operative stay >4days (n=49). Demographic characteristics; fracture and surgical-related characteristics; 30-day and one-year postoperative mortality rates; 30-day postoperative hospital readmission rate; and medical or surgical cause were recorded. Results: In the early discharge group all outcomes were better compared to the non-early discharge group: lower 30-day (0.9% vs 4.1%, P=.16) and 1-year postoperative (4.3% vs 16.3%, P=.009) mortality rates, as well as a lower rate of hospital readmission for medical reasons (7.8% vs 16.3%, P=.037). Conclusions: In the present study, the early discharge group obtained better results 30-day and 1-year postoperative mortality indicators, as well as readmission for medical reasons.(AU)

[Translated article] Lower mortality and readmission in patients with few comorbidities who underwent hip fracture surgery and were discharged early / Menor mortalidad y reingreso en pacientes con pocas comorbilidades intervenidos de fractura de cadera y con alta precoz

Introducción: El retraso preoperatorio en pacientes intervenidos de fractura de cadera (FC) se ha asociado a peores resultados; sin embargo, el momento óptimo del alta hospitalaria tras cirugía ha sido poco estudiado. El objetivo de este estudio fue determinar resultados de mortalidad y de reingreso en pacientes con FC con y sin alta hospitalaria precoz.

¿Debería la herramienta FRAX tener en cuenta otras variables para evaluar la fractura osteoporótica por fragilidad? / Should the FRAX tool include other variables to assess fragility-related osteoporotic fractures?

Introducción y objetivo: el objetivo fue valorar la relevancia de variables no contenidas en el FRAX sobre la incidencia de fractura osteoporótica. Material y métodos: participaron 316 mujeres > 50 años seguidas 8 años. Se evaluaron variables que recoge FRAX (edad, IMC, fractura previa, antecedentes parentales de fractura de cadera, hábito tabáquico, glucocorticoides, DMO cuello femoral) y que no recoge (edad de menarquia, menopausia, años fértiles y nuliparidad). Resultados: edad y antecedentes parentales de fractura de cadera se asociaron con fractura de cadera, pero también edad de menopausia y años fértiles. La edad [odds ratio (OR) = 1,09, Intervalo de confianza del 95 % (IC 95 %) = (1,01-1,17)] y edad de menopausia [OR = 0,90, IC 95 % = (0,82-0,99)] se asociaron con fractura de cadera tras análisis multivariante ajustado por edad e IMC. IMC, DMO en cuello femoral y nuliparidad se asociaron con fractura de Colles. En el análisis multivariante, solo nuliparidad se asoció con fractura de Colles [OR = 4,59, IC 95 % = (1,59-13,26)]. La fractura mayor osteoporótica se asoció significativamente con antecedentes parentales de fractura de cadera, nuliparidad y años fértiles. En el análisis multivariante, antecedentes parentales de fractura de cadera [OR = 3,26, IC 95 % = (1,23-8,61)], nuliparidad [OR = 3,07; IC 95 % = (1,48-6,37)] y años fértiles [OR = 0,92, IC 95 % = (0,87-0,98)] se asociaron con fractura mayor osteoporótica. Conclusiones: de las variables del FRAX, edad y antecedentes parentales de fractura de cadera se asociaron con incidencia de fractura mayor osteoporótica y de cadera, pero otras variables ginecológicas tuvieron un peso similar, lo que sugiere que deben ser tenidas muy en cuenta a la hora de realizar la anamnesis de las pacientes.(AU)

Introduction and objective: the objective of this study was to assess the significance of variables not included in the FRAXtool regarding the incidence of osteoporotic fractures.Materials and methods: a total of 316 women older than 50 years were followed for 8 years. The variables collected (age,BMI, previous fracture, parental history of hip fracture, smoking habit, use of glucocorticoids, femoral neck BMD) and thosenot collected by the FRAX tool (age at menarche, menopause, fertile years, nulliparity) were studied.Results: age and parental history of hip fracture were associated with hip fractures, but so were age at menopause andfertile years. Age [odds ratio (OR), 1.09; 95 % confidence interval (CI), 1.01-1.17] and age at menopause [OR, 0.90; 95 %CI,0.82-0.99] were associated with hip fractures after the multivariate analysis adjusted for age and BMI. BMI, femoral neckBMD and nulliparity were associated with the occurrence of Colles fractures. According to the multivariate analysis, onlynulliparity was associated with Colles fractures [OR, 4.59; 95 %CI, 1.59-13.26)]. Major osteoporotic fractures were signifi-cantly associated with parental history of hip fracture, nulliparity, and fertile years. According to the multivariate analysis,the parental history of hip fracture [OR, 3.26; 95 %CI, 1.23-8.61], nulliparity [OR, 3.07; 95 %CI, 1.48-6.37], and fertile years[OR, 0.92; 95 %CI, 0.87-0.98] were associated with the occurrence of major osteoporotic fractures.Conclusions: among the FRAX variables, age and parental history of hip fracture were associated with the incidence ofmajor osteoporotic and hip fractures. However, the significance of other gynecological variables was similar, which is indic-ative that they should certainlay be taken into consideration during patient history assessment.(AU)

Impacto de la pandemia por COVID-19 y el confinamiento estricto de la población en la incidencia de fractura de cadera en España. Una revisión sistemática / Impact of the COVID-19 pandemic and the strict population confinement on hip fracture incidence in Spain: A systematic review

Antecedentes y objetivo Durante la pandemia por COVID-19, en España se decretó un confinamiento estricto de la población. Ante una situación de crisis sanitaria y de saturación del sistema sanitario resulta de gran importancia para la correcta gestión de recursos y de procesos el conocimiento de las enfermedades cuyo tratamiento no es demorable. El objetivo fue conocer la influencia de la pandemia por COVID-19 y del confinamiento estricto de la población en la incidencia de fractura de cadera en España. Material y método Revisión sistemática siguiendo las guías PRISMA. Búsqueda en Pubmed y Cochrane Library el 11/11/2022: hip fracture AND COVID-19 AND Spain. Resultados Cumplieron los criterios de inclusión 6 estudios, el 50% mostraron un descenso en la incidencia de fracturas de cadera durante el confinamiento estricto (todos en hospitales de la Comunidad de Madrid), y en el otro 50% no hubo diferencias (todos en hospitales de otras comunidades autónomas). Es constante que las fracturas de cadera, o no disminuyeron, o disminuyeron mucho menos que el resto de fracturas durante el período de confinamiento estricto de la población, aumentando su número relativo respecto al total de ingresos en cirugía ortopédica y traumatología. Conclusiones El comportamiento del número de fracturas de cadera durante el confinamiento estricto decretado por la pandemia por COVID-19 no ha sido simétrico en todas las comunidades autónomas. Para diseñar e implementar los planes de contingencia ante una situación de pandemia con adecuada organización de los recursos materiales y de personal, deben ser tenidos en cuenta estos datos (AU)

Background and objectivo During the COVID-19 pandemic, a strict population confinement was decreed in Spain. In a situation of health crisis and health system saturation, knowledge of pathologies whose treatment cannot be delayed is of great importance for the correct management of resources and processes. The objective was to determine the influence of the COVID-19 pandemic and the strict population confinement on hip fracture incidence in Spain. Material and method Systematic review following the PRISMA guidelines. Search in Pubmed and Chocrane Library on 11/11/2022: hip fracture and COVID-19 and Spain Results Six studies met the inclusion criteria, 50% showed a decrease in the hip fractures incidence during strict population confinement (all in Comunidad de Madrid hospitals), and in the other 50% there were no differences (all in other region hospitals). It was constant that hip fractures, either did not decrease, or decreased much less than the rest of fractures during the period of strict population confinement, increasing their relative number with respect to the total admissions in orthopedic surgery and traumatology. Conclusions The behavior of the hip fractures number during the strict population confinement decreed by the COVID-19 pandemic has not been symmetrical in all regions. To design and implement contingency plans in the event of a pandemic situation, these data must be taken into account in order to properly plan material and human resources (AU)

Situación de las Unidades de Recuperación Funcional en ortogeriatría según datos del Registro Nacional de Fractura de Cadera / Functional recovery units state in orthogeriatrics according to data from the National Registry of Hip Fracture

Introducción El Registro Nacional de Fracturas de Cadera (RNFC) facilita el conocimiento del proceso de la fractura de cadera en España tanto para los clínicos como para los gestores y favorece la reducción de la variabilidad de los resultados encontrados incluyendo el destino al alta tras la fractura de cadera. Objetivo Describir la utilización de Unidades de Recuperación Funcional (URF) por parte de los pacientes con fractura de cadera incluidos en el RNFC y comparar los resultados entre las diferentes comunidades autónomas (CC.AA.). Material y métodos Se trata de un estudio observacional, prospectivo y multicéntrico de varios hospitales de España. Se analizaron los datos de una cohorte del RNFC de pacientes ingresados con fractura de cadera entre 2017 y 2022, centrándose en la ubicación al alta de los pacientes, en concreto en el traslado a URF. Resultados De una muestra de 52.215 pacientes procedentes de 105 hospitales, 9540 pacientes (18,1%) se trasladaron a URF al alta y 4595 (8,8%) permanecían en estas unidades 30 días después, con una distribución variable entre las distintas CC.AA. (0-49%) y con resultados variables en deterioro funcional a los 30 días (12,2-41,9%). Conclusiones En el paciente ortogeriátrico existe una disponibilidad y utilización desigual de las URF entre las distintas CC.AA. El estudio de la utilidad de este recurso puede ser de gran valor para la toma de decisiones en políticas de salud (AU)

Introduction The National Registry of Hip Fractures (RNFC) facilitates knowledge of hip fracture process in Spain to clinicians and managers and is useful to the reduction of the results variability, including the destination at discharge after the hip fracture. Objective The aim of this study was to describe functional recovery units (URFs) use for patients with hip fracture included in the RNFC and to compare the results of the different autonomous communities (AC). Material and methods An observational, prospective and multicenter study of several hospitals in Spain. Data from a RNFC cohort of patients admitted with hip fracture between 2017 and 2022 were analyzed, focusing on the location at discharge of the patients, specifically on transfer to the URF. Results 52,215 patients from 105 hospitals were analyzed, 9540 patients (18.1%) were transferred to URF upon discharge and 4595 (8.8%) remained in these units 30 days later, with a variable distribution between the different AC (0–49%) and variability of results in patients not recovering ambulation at 30 days (12.2–41.9%). Conclusions There is in orthogeriatric patient an unequal availability and use of URFs between different autonomous communities. The study of the usefulness of this resource can be of great value for decision-making in health policies (AU)

Estudio piloto para determinar la asociación entre la microbiota intestinal y la fractura de cadera por fragilidad / Pilot study to determine the association between gut microbiota and fragility hip fracture

Introducción: Las fracturas de cadera son la causa más frecuente de ingreso hospitalario en los servicios de ortopedia de Europa y suponen un importante problema sanitario. Por ello, es de gran interés identificar factores de riesgo adicionales que nos ayuden a comprender mejor la fisiopatología de estas fracturas y a mejorar nuestra capacidad preventiva. Existen datos suficientes para apoyar la teoría de la modulación de la masa ósea por la microbiota intestinal (osteomicrobiología); sin embargo, faltan estudios clínicos en humanos que relacionen directamente la microbiota con el riesgo de fractura de cadera. Material y métodos: Estudio observacional, analítico, de casos y controles. La muestra consta de 50 pacientes y se distribuye de la siguiente manera: 25 pacientes ancianos con fractura de cadera por fragilidad y 25 controles sanos sin fractura. Se analizó la microbiota intestinal mediante extracción de ADN de muestras de heces y secuenciación del ADN ribosómico 16S tras la generación de bibliotecas de genes. Resultados: La diversidad alfa reveló una elevación de los estimadores para el nivel taxonómico de clase en el grupo de fracturas de cadera. Los órdenes Bacteroidales, Oscillospirales, Lachnospirales, Peptostreptococcales-Tissierellales y Enterobacterales fueron los órdenes dominantes en ambos grupos. En los pacientes con fractura, se observó un aumento porcentual significativo del orden de Bacteroidales (p<0,001) y Peptostreptococcales-Tissierellales (p<0,005), así como una disminución de las del orden Lachnospirales (p<0,001) respecto a los controles. Conclusiones:Este estudio ha encontrado una asociación entre una microbiota específica en pacientes ancianos con fractura de cadera por fragilidad. Estos hallazgos abren la puerta a nuevas estrategias para prevenir las fracturas de cadera. Es posible que la modificación de la microbiota mediante probióticos se revele como un método eficaz para reducir el riesgo de fractura de cadera.(AU)

Introduction: Hip fractures are the most common cause of hospital admission to orthopaedic departments in Europe and they generate a major health problem. Therefore, it is of great interest to identify additional risk factors that will help us to better understand the pathophysiology of these fractures and improve our preventive capacity. There is sufficient data to support the theory of modulation of bone mass by gut microbiota (osteomicrobiology); however, there is a lack of human clinical studies directly linking microbiota to hip fracture risk. Material and methods: Observational, analytical, case–control study. The sample consisted of 50 patients and it was distributed as follows: 25 elderly patients with fragility hip fracture and 25 subjects without fracture. The intestinal microbiota was determined by DNA extraction from stool samples and 16S ribosomal DNA sequencing after generation of gene libraries. Results: Alpha diversity revealed an elevation of the estimators for the taxonomic class level in the hip fracture group. The orders Bacteroidales, Oscillospirales, Lachnospirales, Peptostreptococcales-Tissierellales and Enterobacterales were the dominant orders in both groups. In patients with fracture, a significant percentage increase in the orders Bacteroidales (p<.001) and Peptostreptococcales-Tissierellales (p<.005) was observed, as well as a decrease in the orders Lachnospirales (p<.001) compared to controls. Conclusions: This study has found an association between a specific microbiota in elderly patients with fragility hip fracture. These findings open the door to new strategies to prevent hip fractures. Modification of the microbiota through probiotics may prove to be an effective method to reduce the risk of hip fracture.(AU)
