[Translated article] A systematic review of the literature: The use of metaphyseal sleeves in revision total knee arthroplasty.

BACKGROUND AND OBJECTIVES: The purpose of this study is to analyse the indications, complications, survivorship and clinical/functional outcome of metaphyseal sleeves as a treatment option in revision total knee arthroplasty. MATERIAL AND METHOD: A systematic review was made following the PRISMA recommendations on the use of metaphyseal sleeves for revision total knee arthroplasty. We included prospective and retrospective studies published in the last 10 years looking at implant survivorship, clinical and functional outcome with a minimum follow-up of 2 years. RESULTS: The included studies showed good both functional and clinical outcomes. The overall reoperation rate was 16.2%, with an overall survival rate of 92.2% and aseptic survivorship of 98.2%. CONCLUSIONS: Metaphyseal sleeves are a good treatment option for this surgery, especially in AORI II or III type bone defects, achieving good intraoperative and primary stability of the implant, with good and rapid osseointegration.

¿Ha influido el confinamiento social por COVID-19 en la mortalidad de la fractura de cadera? Análisis de la mortalidad al año / Has the COVID-19 lockdown influenced the mortality of hip fracture? Analysis of one-year mortality

Introducción y objetivos: El objetivo principal de este estudio es analizar la mortalidad al año en los pacientes con fractura intracapsular de cadera que ingresaron durante un severo confinamiento social en los primeros meses de la pandemia por COVID-19 y compararla con años previos. Material y método: Estudio observacional retrospectivo en el que se comparó una cohorte del 14 marzo al 21 de junio de 2020 (grupo pandemia, n = 62) con una cohorte control en las mismas fechas de los años 2017, 2018 y 2019 (grupo control, n = 172). Se midieron la mortalidad a los 30 días y al año, complicaciones ortopédicas, grado ASA, comorbilidades, diagnóstico y tratamiento, tiempo hasta cirugía y estancia hospitalaria. Resultados: No se encontraron diferencias significativas en la mortalidad a los 30 días (p = 0,156; 9,7% vs. 4,7%) ni en la mortalidad anual (p = 0,47) entre el grupo pandemia (21%) y el control (16,9%). Se objetivó un descenso de la demora quirúrgica y de la estancia media en el grupo pandemia, aunque sin significación estadística. Conclusión: El estado de alarma modificó la distribución del tipo de fractura de cadera con un predominio de la fractura intracapsular. Mantener el mismo manejo hospitalario que previo a la pandemia permitió no incrementar la mortalidad a los 30 días y al año en los pacientes con fractura intracapsular de cadera.(AU)

Introduction and objectives: The main objective of this study is to analyze the one-year mortality in patients with intracapsular hip fracture who were admitted during severe social confinement in the first months of the COVID-19 lockdown and compare it with previous years. Material and methods: Retrospective observational study in which a cohort from March 14 to June 21, 2020 (pandemic group, n = 62) was compared with a control cohort on the same dates in the years 2017, 2018 and 2019 (control group, n = 172). Thirty-day-mortality and one-year-mortality, orthopedic complications, ASA grade, comorbidities, diagnosis and treatment, time to surgery and mean stay were measured. Results: No significant differences were found in 30-day mortality (p = 0.156; 9.7% compared to 4.7%) or in one-year mortality (p = 0.47) between the pandemic group (21%) and the control one (16.9%). A decrease in surgical delay and mean stay was observed in the pandemic group, although without statistical significance. Conclusión: The State of Alarm modified the distribution of the type of hip fracture with a predominance of intracapsular fracture. Maintaining the same hospital management as prior to the pandemic period made it possible not to increase 30-day mortality and one-year mortality in patients with intracapsular hip fracture.(AU)

Epidemiology of Bone Fractures in the Hand in Adult Population Using the ICD-10 Classification.

PURPOSE OF THE STUDY The purpose of this study was to conduct an epidemiological study of hand fractures in adult population. MATERIAL AND METHODS A retrospective observational study in a population of 470,000 habitants was performed. Over the course of three years, all patients over 16 years of age who were diagnosed with fracture or fracture-dislocation at the level of a carpal bone, metacarpal and/or phalange were included. These fractures were classified according to the International Classification of Diseases 10th edition (ICD-10). Incidence rates, along with gender and age distribution were also studied. RESULTS 1,267 patients with a total of 1,341 hand fractures were included. They represented 29.7% of all upper limb fractures and 7.6% of all traumatological emergencies involving a bone fracture during that period. The most frequent ICD-10 group was S62.3, with the fifth metacarpal as the most often affected bone (39.7%). The most frequent location at the level of the phalanges (S62.5) was the proximal third of the proximal phalanx of the fifth radius. The global incidence rate was 99 fractures per 100,000 persons/year. No seasonal variation was observed. Only 10.2% of hand fractures received surgical treatment. DISCUSSION Several epidemiological studies have been published on fractures in the hand, but none have used the ICD-10 classification. Although the distribution of our stratified sample by age and gender was similar to those previously published, the incidence rate in our study was much lower. We may possibly extrapolate our results to the rest of the Spanish population and even to the rest of the population of southern Europe, given the scarcity of epidemiological studies on this matter in these geographical areas. CONCLUSIONS The ICD-10 classification is useful for the description and classification of hand fractures. The most often affected group is that including metacarpals of the long fingers (S62.3), being the distal level of the fifth metacarpal in young male patients the most frequent one. Most fractures are treated conservatively and in case of surgical treatment, the preferred surgical techniques include K-wire fixation, interfragmentary compression screws and plate osteosynthesis. Key words: epidemiology, incidence, fracture, fracture dislocation, carpal bones, metacarpals, finger phalanges.

Prospective study about orthopaedic treatment of fifth metacarpal neck fractures. / Estudio prospectivo sobre el tratamiento conservador de las fracturas de cuello de quinto metacarpiano.

INTRODUCTION: The fifth metacarpal neck fracture is traditionally treated with closed reduction and intrinsic plus cast immobilization. Another alternative and more functional treatment is the syndactylia. The aim of our study is to compare both treatments searching for any differences in their functional outcomes. METHOD: We did a prospective, controlled, masked, randomized cohort study with patients over 18 years old attended from May 2019 to May 2020 in Vigo's Sanitary Area with this injure and an angle below 40°. The collected data was: sex, age, fracture angle, range of motion of the metacarpophalangeal articulation (MCFA), grip strength, pain, fracture consolidation, Quick DASH and comfort 4 and 6 weeks after the injury. RESULTS: 39 men and 1 woman were included in the sample. 36.1 years old as the age average. 90% of the injuries affected the right hand, being all the patients right-handed, finding statistically significant differences in MCFA flexion within 4 weeks and in grade of discomfort, both in favour of the syndactylia (p<0.05). Any of the other collected data was statistically significant. Every fracture achieved consolidation at the end of the follow-up. CONCLUSION: Following the results, we consider both immobilizations good treatment options of these fractures; nevertheless, syndactylia has proven an earlier MCFA flexion recovery and a better tolerance.

Introducción: La fractura de cuello del quinto metacarpiano se trata tradicionalmente mediante la reducción cerrada e inmovilización con férula en intrínseco plus. Una alternativa es el tratamiento funcional mediante sindactilia. Nuestro objetivo es comparar ambos tratamientos buscando diferencias de resultado funcional entre ambas opciones. Método: Realizamos un estudio de cohortes prospectivo, controlado, enmascarado y aleatorizado con pacientes mayores de 18años con esta lesión y angulación<40°, atendidos entre mayo de 2019 y mayo de 2020 en el Área Sanitaria de Vigo. Se recogieron las variables: sexo, edad, lado, angulación de la fractura, movilidad de la articulación metacarpofalángica (MCF), fuerza de prensión, dolor, consolidación de la fractura, Quick DASH y grado de satisfacción y confort. Esta información fue recogida a las 4 y a las 6 semanas. Resultados: La muestra constó de 39 hombres y una mujer. La edad media fue de 36,1años. El 90% afectó a la mano derecha siendo todos los pacientes diestros, encontrando diferencias estadísticamente significativas en la flexión de la articulación MCF a las 4 semanas y en el grado de molestia de la inmovilización, ambos en favor de la sindactilia (p<0,05). El resto de variables recogidas no mostraron significación estadística. En todos los pacientes se consiguió la consolidación de la fractura. Conclusión: A raíz de los resultados obtenidos, consideramos que ambas inmovilizaciones pueden utilizarse en el tratamiento de estas fracturas; sin embargo, la sindactilia demuestra una movilidad en flexión de la articulación MCF más temprana y mejor tolerancia.(AU)

Influence of integrated orthogeriatric care on morbidity and mortality and length of hospital stay for hip fracture / Influencia de la atención ortogeriátrica integrada en la morbimortalidad y el tiempo de estancia hospitalaria de la fractura de cadera

Background and objectives: Compare the morbidity and mortality, the length of hospital stay and the economic cost of the fragility fracture of the hip, in two nonconsecutive years thanks to the integrated orthogeriatric care. Material and method: Retrospective observational cohort study with 633 patients with hip fragility fracture with a mean age of 85.5 years, treated in the same Trauma and Orthopaedic Surgery service in two different years (2012 and 2017). Mean stay, surgical delay, perioperative mortality, one month and one year, and perioperative complications such as acute urine retention, pressure ulcers, and need for transfusion were measured. Results: Mortality during admission decreased from 10% in 2012 to 3.6% in 2017 (P=.004 *), while mortality at thirty days (10.5% vs 7%) (P=.123) and one year (28.9% versus 24.9%) (P=.277). Hospital stay times, surgical delay, and postoperative admission time also decreased. The estimated total annual economic savings thanks to integrated orthogeriatric care amounted to €1,017,084.94. Conclusions: Integrated orthogeriatric care of the patient with fragility fracture of the hip, results in a more effective and efficient care model. Both the care and the clinical situation of patients are improved in the perioperative period, both hospital stay and mortality during admission are significantly reduced, and all this with significant associated economic savings.(AU)

Estudio epidemiológico de las fracturas de la extremidad distal de radio en el área sanitaria de Vigo / Epidemiological study of distal radius fractures in the sanitary area of Vigo

Introducción: Las fracturas de la extremidad distal de radio (FEDR) representan una carga cada vez mayor para los recursos sanitarios debido a los cambios demográficos de la población y a las estrategias de gestión, por lo que la comprensión precisa de su epidemiología es esencial. Presentamos un estudio epidemiológico de FEDR y lo comparamos con otras áreas de la península y Europa. Método: Se recogieron todas las FEDR de nuestra área sanitaria registradas en 2017 y 2018 en pacientes mayores de 18años de forma retrospectiva y observacional agrupándolos según la clasificación de AO-OTA. Se analizaron las variables de edad, sexo, época del año, mecanismo de fractura, presencia de lesiones asociadas y tratamiento realizado. Resultados: Registramos 1.121 FEDR en 1.108 pacientes, 903 mujeres (81,5%) y 205 varones (18,5%). En 612 casos se vio afectado el lado izquierdo (54,6%) y en 509 el lado derecho (45,4%). La edad media de la muestra fue de 65,9años (IC95%: 65-66,9años). La tasa de incidencia de FEDR fue de 158,5 fracturas por 100.000 habitantes/año. El 49,2% se clasificaron como tipo A de AO-OTA y se intervinieron quirúrgicamente un 19%. Conclusión: La incidencia de FEDR alcanza un máximo en la sexta década tanto en hombres como en mujeres. Las fracturas de tipo A de la clasificación AO-OTA son las más frecuentes. La mayoría se trataron de forma conservadora. El patrón de paciente tratado quirúrgicamente con más frecuencia es el de una mujer mayor de 50años con FEDR articular compleja.(AU)

Introduction: Distal radius fractures (DRF) are being a bigger burden for health resources as changes continue to happen in our population demography and in management strategies, so a precise epidemiologic comprehension is mandatory. We present a DRF epidemiology study and we compared it with other sanitary areas of the Iberian Peninsula and Europe. Method: Every DRF in our sanitary area registered between 2017 and 2018 in patients older than 18 years old were observational and retrospectively recorded and classified using AO-OTA classification. Age, sex, season of the year, mechanism of injury, presence of associated injuries and type of treatment were analysed. Results: 1,121 DRF in 1,108 patients, 903 women (81.5%) and 205 men (18.5%), were registered. Left side was affected in 612 cases (54.6%) and right side in 509 cases (45.4%). The average age of our sample was 65.9 years old (CI95%: 65-67.9 years old). The incidence rate of DRF in our population was 158.5 fractures per 100,000 people-year; 49.2% were classified as type A of AO-OTA classification and 19% were treated surgically. Conclusion: Incidence of DRF had a maximum during males and women sixth decade of age. Type A fractures of AO-OTA classification were the most frequent. Most part of the fractures were treated non-surgically. The usual patient treated surgically was a woman, over 50 years old with a distal radius intraarticular complex fracture.(AU)

Método: Se recogieron todas las FEDR de nuestra área sanitaria registradas en 2017 y 2018 en pacientes mayores de 18años de forma retrospectiva y observacional agrupándolos según la clasificación de AO-OTA. Se analizaron las variables de edad, sexo, época del año, mecanismo de fractura, presencia de lesiones asociadas y tratamiento realizado. Resultados: Registramos 1.121 FEDR en 1.108 pacientes, 903 mujeres (81,5%) y 205 varones (18,5%). En 612 casos se vio afectado el lado izquierdo (54,6%) y en 509 el lado derecho (45,4%). La edad media de la muestra fue de 65,9años (IC95%: 65-66,9años). La tasa de incidencia de FEDR fue de 158,5 fracturas por 100.000 habitantes/año. El 49,2% se clasificaron como tipo A de AO-OTA y se intervinieron quirúrgicamente un 19%. Conclusión: La incidencia de FEDR alcanza un máximo en la sexta década tanto en hombres como en mujeres. Las fracturas de tipo A de la clasificación AO-OTA son las más frecuentes. La mayoría se trataron de forma conservadora. El patrón de paciente tratado quirúrgicamente con más frecuencia es el de una mujer mayor de 50años con FEDR articular compleja.(AU)

Epidemiological study of distal radius fractures in the sanitary area of Vigo. / Estudio epidemiológico de las fracturas de la extremidad distal de radio en el área sanitaria de Vigo.

INTRODUCTION: Distal radius fractures (DRF) are being a bigger burden for health resources as changes continue to happen in our population demography and in management strategies, so a precise epidemiologic comprehension is mandatory. We present a DRF epidemiology study and we compared it with other sanitary areas of the Iberian Peninsula and Europe. METHOD: Every DRF in our sanitary area registered between 2017 and 2018 in patients older than 18 years old were observational and retrospectively recorded and classified using AO-OTA classification. Age, sex, season of the year, mechanism of injury, presence of associated injuries and type of treatment were analysed. RESULTS: 1,121 DRF in 1,108 patients, 903 women (81.5%) and 205 men (18.5%), were registered. Left side was affected in 612 cases (54.6%) and right side in 509 cases (45.4%). The average age of our sample was 65.9 years old (CI95%: 65-67.9 years old). The incidence rate of DRF in our population was 158.5 fractures per 100,000 people-year; 49.2% were classified as type A of AO-OTA classification and 19% were treated surgically. CONCLUSION: Incidence of DRF had a maximum during males and women sixth decade of age. Type A fractures of AO-OTA classification were the most frequent. Most part of the fractures were treated non-surgically. The usual patient treated surgically was a woman, over 50 years old with a distal radius intraarticular complex fracture.

Influence of integrated orthogeriatric care on morbidity and mortality and length of hospital stay for hip fracture. / Influencia de la atención ortogeriátrica integrada en la morbimortalidad y el tiempo de estancia hospitalaria de la fractura de cadera.

BACKGROUND AND OBJECTIVES: Compare the morbidity and mortality, the length of hospital stay and the economic cost of the fragility fracture of the hip, in two nonconsecutive years thanks to the integrated orthogeriatric care. MATERIAL AND METHOD: Retrospective observational cohort study with 633 patients with hip fragility fracture with a mean age of 85.5 years, treated in the same Trauma and Orthopaedic Surgery service in two different years (2012 and 2017). Mean stay, surgical delay, perioperative mortality, one month and one year, and perioperative complications such as acute urine retention, pressure ulcers, and need for transfusion were measured. RESULTS: Mortality during admission decreased from 10% in 2012 to 3.6% in 2017 (P=.004 *), while mortality at thirty days (10.5% vs 7%) (P=.123) and one year (28.9% versus 24.9%) (P=.277). Hospital stay times, surgical delay, and postoperative admission time also decreased. The estimated total annual economic savings thanks to integrated orthogeriatric care amounted to €1,017,084.94. CONCLUSIONS: Integrated orthogeriatric care of the patient with fragility fracture of the hip, results in a more effective and efficient care model. Both the care and the clinical situation of patients are improved in the perioperative period, both hospital stay and mortality during admission are significantly reduced, and all this with significant associated economic savings.

Prepartum behavior changes in dry Holstein cows at risk of postpartum diseases.

The objective of this study was to identify changes in prepartum behavior associated with the incidence of postpartum diseases in dairy cows. Multiparous Holstein cows (n = 489) were monitored with accelerometers for 3 wk prepartum. Accelerometers measured steps, time at the feed bunk, frequency of meals, lying bouts, and lying time. Postpartum health was monitored from 0 to 30 d in milk and cases of metritis, mastitis, retained placenta, displaced abomasum (DA), ketosis, and hypocalcemia were recorded. A multivariate linear mixed model was used to assess differences in behavior between diseased and not diagnosed diseased cows. A multivariate logistic regression was used to predict the occurrence of diseases. Predictors were selected using a manual backward stepwise selection process of variables until all remaining predictors had a P < 0.10. Models were submitted to a leave-one-out cross-validation process, and sensitivity, specificity, false discovery rate, and false omission rate were calculated. On average, over the 3-wk prepartum period, cows not diagnosed diseased (n = 345) took 1,613 ± 38 steps, spent 181 ± 7.1 min at the feed bunk, had 8.3 ± 0.17 meals, had 9.8 ± 0.32 lying bouts, and spent 742 ± 11.3 min lying per day. Behavior of diseased cows (n = 144) did not differ from those not diagnosed diseased. However, differences for specific diseases were observed, being significant in the week prepartum. When considering changes in behavior for only the week before calving, cows with metritis had more lying bouts (+21%), cows with DA had fewer meals (-24%) and tended to take fewer steps (-18%), and cows with ketosis had fewer meals (-22%) and spent less time at the feed bunk (-40%). Prediction models with the best outcomes were found for DA and ketosis using data of the prepartum week only. The model for DA included time at the feed bunk. Cross-validation resulted in a 80% sensitivity, 58.1% specificity, 59.2% accuracy, 91.2% false discovery rate, and 1.7% false omission rate. The model for ketosis included time at the feed bunk and number of meals. Cross-validation resulted in 64.3% sensitivity, 59.3% specificity, 59.5% accuracy, 93.0% false discovery rate, and 2.8% false omission rate. Prepartum behavior of cows affected with metritis, DA, and ketosis was different from that of cows not diagnosed with diseases. Prediction equations were able to classify cows at high or low risk of ketosis and DA and can be used in taking management decisions, but the high false discovery rates requires further refinement.

Pitavastatin ameliorates autoimmune neuroinflammation by regulating the Treg/Th17 cell balance through inhibition of mevalonate metabolism.

While Treg cells are responsible for self-tolerance and immune homeostasis, pathogenic autoreactive Th17 cells produce pro-inflammatory cytokines that lead to tissue damage associated with autoimmunity, as observed in multiple sclerosis. Therefore, the immunological balance between Th17 and Treg cells may represent a promising option for immune therapy. Statin drugs are used to treat dyslipidemia; however, besides their effects on preventing cardiovascular diseases, statins also have anti-inflammatory effects. Here, we investigated the role of pitavastatin on experimental autoimmune encephalomyelitis (EAE) and the differentiation of Treg and Th17 cells. EAE was induced by immunizing C57BL/6 mice with MOG35-55. EAE severity was determined by analyzing the clinical score and inflammatory parameters in the spinal cord. Naive CD4 T cells were cultured under Treg and Th17-skewing conditions in vitro in the presence of pitavastatin. We found that pitavastatin decreased EAE development, which was accompanied by a reduction of all parameters investigated. Pitavastatin also reduced the expression of IBA1 and pSTAT3 (Y705 and S727) in the spinal cords of EAE mice. Interestingly, the reduction of Th17 cell frequency in the draining lymph nodes of EAE mice treated with pitavastatin was followed by an increase of Treg cells. Indeed, pitavastatin directly affects T cell differentiation in vitro by decreasing Th17 and increasing Treg cell differentiation. Mechanistically, pitavastatin effects are dependent on mevalonate synthesis. Thus, our data show the potential anti-inflammatory effect of pitavastatin on the pathogenesis of the experimental neuroinflammation by modulating the Th17/Treg axis.

Evaluation of the primary stability in dental implants placed in low density bone with a new drilling technique, Osseodensification: an in vitro study.

BACKGROUND: Primary stability is an important key determinant of implant osseointegration. We investigated approaches to improve primary implant stability using a new drilling technique termed osseodensification (OD), which was compared with the conventional under-drilling (UD) method utilized for low-density bones. MATERIAL AND METHODS: We placed 55 conical internal connection implants in each group, in 30 low-density sections of pig tibia. The implants were placed using twist drill bits in both groups; groups Under Drilling (UD) and Osseodensification (OD) included bone sections subjected to conventional UD and OD drilling, respectively. Before placing the implants, we randomized the bone sections that were to receive these implants to avoid sample bias. We evaluated various primary stability parameters, such as implant insertion torque and resonance frequency analysis (RFA) measurements. RESULTS: The results showed that compared with implants placed using the UD technique, those placed using the OD technique were associated with significantly higher primary stability. The mean insertion torque of the implants was 8.87±6.17 Ncm in group 1 (UD) and 21.72±17.14 Ncm in group 2 (OD). The mean RFA was 65.16±7.45 ISQ in group 1 (UD) and 69.75±6.79 ISQ in group 2 (OD). CONCLUSIONS: The implant insertion torque and RFA values were significantly higher in OD group than in UD. Therefore, compared with UD, OD improves primary stability in low-density bones (based on torque and RFA measurements).
