Factores de riesgo asociados a infección periprotésica en el paciente con fractura del cuello femoral: estudio de casos y controles / Risk factors associated with periprosthetic infection in patients with femoral neck fracture: A case-control study

Antecedentes y objetivo: La infección es una de las complicaciones locales más importantes en el paciente con fractura del cuello femoral tratada con una artroplastia. El objetivo del presente estudio es describir y analizar posibles factores de riesgo que podrían estar implicados en la infección periprotésica del paciente con fractura del cuello femoral. Material y métodos: Se realizó un estudio de casos y controles retrospectivo que incluye a pacientes con fractura del cuello femoral tratada con una artroplastia en el periodo comprendido entre enero de 2015 y diciembre de 2017. Se definieron como casos a los pacientes con fractura del cuello femoral que tras someterse a una artroplastia (hemiartroplastia o artroplastia total de cadera) tuvieron como desenlace una infección periprotésica, cuyo diagnóstico se llevó a cabo atendiendo a los criterios mayores y menores descritos en el Consenso Internacional de Infecciones Musculoesqueléticas (Philadelphia 2018). Con la intención de atenuar la influencia de variables que podrían considerarse confusoras, se realizó un análisis multivariante. Resultados: Se apreció una asociación estadísticamente significativa entre infección periprotésica y determinadas variables presentes en el momento del ingreso, entre las que se encuentran la presencia de anemia moderada o severa (OR: 10,91; IC95%: 1,07-111,50; p=0,007), trombocitopenia (OR: 27,72; IC95%: 3,48-221,01; p=0,002), el antecedente tromboembólico (OR: 8,80; IC95%: 1,31-59,38; p=0,026), el trastorno ansioso-depresivo en tratamiento con 2 o 3 fármacos (OR: 21,36; IC95%: 3,65-125,12; p=0,001) y la hepatopatía (OR: 32,04; IC95%: 2,59-396,29; p=0,007). Conclusiones: La infección periprotésica en el paciente con fractura del cuello femoral tratado con una artroplastia podría relacionarse con la presencia de determinadas variables en el momento del ingreso hospitalario, entre las que se encuentran la anemia moderada o severa...(AU)

Background: Infection is one of the most important local complications in the patient with femoral neck fracture treated with arthroplasty. The aim of the present study is to describe and analyze possible risk factors that could be involved in periprosthetic infection in the patient with femoral neck fracture. Methods: A retrospective case-control study was performed including patients with femoral neck fractures treated with arthroplasty in the period between January 2015 and December 2017. Cases were defined as patients with femoral neck fracture who after undergoing arthroplasty (hemiarthroplasty or total hip arthroplasty) had a periprosthetic infection, whose diagnosis was carried out according to the major and minor criteria described in the International Consensus on Musculoskeletal Infections (Philadelphia 2018). In order to mitigate the influence of variables that could be considered confounding variables, a multivariate analysis was carried out. Outcomes: A statistically significant association was found between periprosthetic infection and certain variables present at the time of admission, including the presence of moderate or severe anaemia (OR: 10.91; 95%CI: 1.07-111.50; P=.007), thrombocytopenia (OR: 27.72; 95%CI: 3.48-221.01; P=.002), history of thromboembolism event (OR: 8.80; 95%CI: 1.31-59.38; P=.026), anxious-depressive disorder in treatment with two or three drugs (OR: 21.36; 95%CI: 3.65-125.12; P=.001) and liver disease (OR: 32.04; 95%CI: 2.59-396.29; P=.007). Conclusions: Periprosthetic infection in the patient with femoral neck fracture treated with arthroplasty could be related to the presence of certain variables at the time of hospital admission, including moderate or severe anaemia, thrombocytopenia, history of thromboembolic event, anxious-depressive disorder in treatment with two or three drugs or liver disease.(AU)

[Influence of medical outliers in patients with femoral neck fracture]. / Influencia del ingreso hospitalario ectópico en pacientes con fractura del cuello femoral.

OBJECTIVES: The objective is to describe and analyze how outlier admission influences hospital stay and the appearance of complications in patients with a femoral neck fracture treated with arthroplasty. MATERIAL AND METHOD: A historical cohort study was carried out in which the group of patients with a displaced fracture of the femoral neck who had an outlier admission was defined as an exposed cohort, that is, they were admitted to a hospitalization area not belonging to the Orthopedic Surgery and Traumatology department, unlike the unexposed cohort, that included patients admitted to a hospitalization area assigned to the Orthopedic Surgery and Traumatology department. RESULTS: Outlier admission was a risk factor for requiring a postoperative transfusion (RR 1.52, 95% CI 1.05-2.21; P=.035), to have a postoperative stay longer than 5 days (RR 1.35, 95% CI 1.04-1.74; P=.038) and to suffer general postoperative complications (RR 1.35, 95% CI 1.02-1.78; P=.048). CONCLUSIONS: Outlier admission is a threat to the quality and safety of health care. In patients over 80 years of age, medical outliers is a risk factor for postoperative transfusion and systemic postoperative complications.

The result of the use of remote consultation in orthopaedic and trauma surgery during the COVID-19 pandemic.

The COVID pandemic has made telematic consultations a basic tool in daily practice. AIMS: The main objective of the study is to assess the results of the application of telematic consultations to limit the mobility of patients.The operational objectives are; to propose a consultation plan, to know how attendance limits consultations and to define which pathologies benefit the most from this plan. METHODS: A scheme is proposed with the creation of pre-scheduled clinic to assess suitability and the possibility of carrying them out in a single non face-to-face act. RESULTS: Phone call to 5619 patients were made with a lack of response of 19%The cases of 74% of the patients that answered were resolved virtually. There is a difference between units, obtaining a higher answering rate from patients appointed to specific clinic units, OR = 0.60, or to general trauma ones, OR = 0.67. The lowest answering rate was obtained from those derived from the emergency department.Twenty per cent of the consultations were not accompanied by complementary tests that would have favored the resolution in a single act. The general trauma consultations, OR = 0.34, postoperative control, OR = 0.49, and specific unit ones, OR = 0.40, were the ones that better met this requirement.Out of the remaining patients, the general trauma consultations, OR = 0.50, and those referred to units, OR = 0.54, were the ones that had a higher resolution rate without in- person consultation. CONCLUSIONS: The cases of 74% of the patients who answered the phone call were resolved virtually.Cases of 20% of the patients cannot be solved in a single act because they are derived without complementary tests.Osteosynthesis and postoperative arthroscopic follow-up consultations are the ones that need to be carried out in person the most.

MATERIAL Y MÉTODOS: Se propone un esquema con la creación de consultas previas a las agendadas para valorar idoneidad y posibilidad de realizarla en acto único no presencial. RESULTADOS: Se han realizado 5619 consultas con una falta de respuesta telefónica del 19%.El 74% de los pacientes fueron resueltos de forma virtual. Existe diferencia entre unidades, siendo mas probable la respuesta telefónica para las consulta de unidad, OR = 0.60 o de traumatología general, OR = 0.67 y menos para los derivados desde urgencias.El 20% de las consultas no se acompañaban de pruebas complementarias. Las consultas de traumatología general, OR = 0.34, control postoperatorio, OR = 0.49, y unidades, OR = 0.40, cumplieron mejor este requisito.De los pacientes restantes, las consultas de traumatología general, OR = 0.50, y las derivadas a unidades, OR = 0.54, fueron las que se mas se resolvieron sin acudir presencialmente. CONCLUSIONES: Se han resuelto de forma no presencial el 74% de los pacientes que atendieron a la llamada telefónica. El 20% de los pacientes acuden a la visita sin pruebas complementarias. Las consultas de seguimiento de osteosíntesis y postoperatorio de cirugía artroscópica son las que mas precisan de ser realizadas de forma presencial.

Biomechanical models of in vitro constructs for spinopelvic osteosynthesis.

Spinopelvic lesions are the result of high-energy vertical trauma with axial skeletal overload where the spine impacts onto the sacrum, dissociating the lumbar spine from the pelvis. Therefore, lumbopelvic instrumentations are aimed to counteract these vertical forces, although various biomechanical aspects of the combinations of different constructs (with or without iliosacral screws) or the number of lumbar fixation levels (L5 or the combination of L5 with L4) are subject to controversy. The number of patients in each published series is too short, and the nature of the fixation is very different from one article to another, making comparison very difficult. In this paper the methodology for laboratory studies is discussed. The design of the test bench fixture, biomechanical testing protocol and data analysis are very important when inference to the clinical setting is desired.

Quality of life after Girdlestone resection arthroplasty. / Calidad de vida tras artroplastia resección de Girdlestone.

MAIN AIM: To know the result of the Girdlestone resection arthroplasty in the treatment of the infected hip arthroplasty. SECONDARY AIMS: To analyze the effectiveness in the control of pain and infection, the functional outcome and to contrast factors correlated with the final result. PATIENTS AND METHODS: Case series with a total of 17 patients. The control of the infection was assessed according to the presence or absence of sinus, and the clinical status using EuroQol 5D scale, residual pain and limb length discrepancy. OUTCOMES: The most common infecting germ at the time of removal of the arthroplasty was Staphylococcus CN and one patient presented infection by Candida albicans. In 2 patients the draining sinus persisted. The residual dysmetria was 5.24cm. In the EQ-5D scale, the most affected dimensions were mobility, need for help for self-care and ability to carry out activities of daily life. 8 patients maintained, pain levels worse than 4 in the VAS. The variables of dysmetria were correlated inversely with health index (-0,54) and self-perceived general health status (-0,45). CONCLUSIONS: The Girdlestone resection arthroplasty is an alternative in the treatment of the infected hip arthroplasty. Patient perception is inversely corelated to residual dysmetria. The dysmetria is greater in women and in ages over 65 years.

Estacionalidad en incidencia y mortalidad en las fracturas de cadera / Seasonality in incidence and mortality of hip fracture

Objetivo: Determinar si existe relación estacional en la incidencia y en la mortalidad intrahospitalaria de los pacientes con fractura de cadera. Pacientes y métodos: Estudio descriptivo longitudinal de casos que incluye 1.104 pacientes mayores de 64años ingresados por fractura de la extremidad proximal del fémur en el Hospital Clínico Universitario Virgen de la Victoria de Málaga durante un periodo de 30meses. Se registraron las características epidemiológicas de los pacientes y se relacionó la incidencia mensual de fracturas con el mes del año en que ocurre, y con las condiciones meteorológicas: temperatura y pluviometría. Resultados: La población estudiada la componen un total de 1.104 pacientes, con mayor proporción de mujeres (75,1%). La edad media fue de 82,3años. Se ha hallado una tendencia al aumento de la incidencia de estas fracturas. La tasa anual de mortalidad durante la estancia hospitalaria fue del 2,97%, siendo mayor entre hombres y en el grupo de edad de más de 84años. Se ha encontrado una estacionalidad en cuanto a la aparición de fracturas por encima de la media en el mes de octubre y por debajo de esta en el mes de febrero. Por su parte, la mortalidad es inferior a la media en el mes de marzo y superior en el mes de agosto. En ambas se ha encontrado una correlación baja con temperatura y pluviometría. Conclusiones: La distribución estacional de las fracturas de cadera presenta aumento sobre la media en octubre y disminución en febrero La mortalidad se eleva sobre la media en agosto y disminuye en marzo

Objectives: To determine whether there is a seasonal relationship in the incidence and in-hospital mortality of patients with hip fracture. Patients and methods: Longitudinal descriptive study of cases that included 1104 patients older than 64years admitted for fracture of the proximal extremity of the femur in the Hospital HCU Virgen de la Victoria during a period of 30months The epidemiological characteristics of the patients were recorded and the monthly incidence of fractures was related with the month of the year in which it occurred, as well as with the meteorological conditions, temperature and rainfall. Results: The study population comprised a total of 1104 patients, with a greater proportion of women (75.1%). The average age was 82.3years. A tendency towards an increased incidence of these fractures was found. The in-hospital annual mortality rate was 2.97%, higher for men and in the age group over 84years. Seasonality was found in terms of the incidence of fractures above the average in the month of October and below this in the month of February. On the other hand, mortality was lower than the average in the month of March and higher in August. In both, a low correlation with temperature and rainfall was found. Conclusions: The seasonal distribution of hip fractures presented an increase over the average in the month of October and a decrease in February. Mortality increased over the average in the month of August and decreased in March

Trunionosis: qué es y en qué me afecta / Trunnionosis: What is it?

La trunionosis se define como el desgaste que se produce a nivel de la interfaz cabeza-cuello femoral y recientemente se ha reconocido como una causa de fallo de la prótesis total de cadera. Es responsable del 3% del total de revisiones de artroplastia total de cadera. La causa exacta es desconocida, aunque se han postulado como posibles etiologías el desgaste en la unión modular, corrosión y las partículas de iones metálicos. Para evitarlo, se recomienda usar preferiblemente cabezas de cerámica, usar cuellos cortos y con poco offset si es posible, y con cabezas no excesivamente grande

Trunnionosis is defined as wear of the femoral head-neck interface, has recently been acknowledged as a cause of total hip arthroplasty failure. It is responsible of 3% of all total hip arthroplasty revisions. The exact cause is unknown, however postulated etiologies included modular junction wear, corrosion damage, and metal ions. To prevent this, it is recommended to use ceramic heads, use short necks and with low offset if possible, and with heads not too large

Adult stem cells applied to tissue engineering and regenerative medicine.

Regeneration takes place in the body at a moment or another throughout life. Bone, cartilage, and tendons (the key components of the structure and articulation in the body) have a limited capacity for self-repair and, after traumatic injury or disease, the regenerative power of adult tissue is often insufficient. When organs or tissues are irreparably damaged, they may be replaced by an artificial device or by a donor organ. However, the number of available donor organs is considerably limited. Generation of tissue-engineered replacement organs by extracting stem cells from the patient, growing them and modifying them in clinical conditions after re-introduction in the body represents an ideal source for corrective treatment. Mesenchymal stem cells (MSCs) are the multipotential progenitors that give rise to skeletal cells, vascular smooth muscle cells, muscle (skeletal and cardiac muscle), adipocytes (fat tissue) and hematopoietic (blood)-supportive stromal cells. MSCs are found in multiple connective tissues, in adult bone marrow, skeletal muscles and fat pads. The wide representation in adult tissues may be related to the existence of a circulating blood pool or that MSCs are associated to the vascular system.

Resultados del tratamiento quirúrgico en las fracturas de pelvis / Results of the surgical treatment of pelvic fractures

Objetivo. Evaluar los resultados clínicos y radiológicos obtenidos tras el tratamiento quirúrgico de las fracturas del anillo pélvico. Material y método. Se analizan en esta revisión un total de 23 pacientes que han sido tratados quirúrgicamente por presentar una fractura de pelvis y de los que se ha obtenido un seguimiento completo con un mínimo de tres años. Resultados. La edad media de los enfermos en el momento del accidente ha sido de 32 años (13-59) y ha habido un predominio del sexo masculino (19:4). La fractura más frecuente ha sido la de tipo C3 (7 casos). El trayecto de la línea de fractura se ha localizado en 7 ocasiones a través de la región transacroilíaca. Las lesiones acompañantes se han presentado en 21 de los 23 enfermos y ha sido la fractura de algún hueso de la extremidad inferior la que lo ha hecho en más ocasiones (14 veces). El tratamiento más frecuente en urgencias ha sido la inmovilización mediante fijación externa. El tratamiento definitivo se ha realizado de preferencia a través del abordaje a la región posterior. El tiempo medio de seguimiento ha sido de 5,74 años (3,14-10,02). El 48% de los pacientes presentan algún grado de cojera residual y 8 de cada 23 tienen clínica dolorosa. Cuatro enfermos presentan dismetría de miembros inferiores superior a 2 cm. En tres permanece como secuela una oblicuidad pélvica. En los resultados radiológicos se ha conseguido una reducción perfecta en 18 pacientes en la parte anterior del anillo pélvico, y en 13 ocasiones en la parte posterior. En 5 casos se ha diagnosticado un trastorno de la consolidación y en el 86,4% de los pacientes se han evidenciado signos radiológicos compatibles con el diagnóstico de artrosis. Conclusiones. A pesar de una correcta reducción quirúrgica de los fragmentos óseos, la clínica dolorosa, así como la persistencia de dismetría y la cojera son secuelas frecuentes en este tipo de lesiones. A pesar de las cifras porcentuales, probablemente debido a lo limitado de la casuística, no se han podido identificar factores del cuadro inicial, ni características del resultado quirúrgico, relacionados con el resultado final del tratamiento quirúrgico de las fracturas de pelvis

Purpose. To examine the clinical and radiological results obtained after surgical treatment of pelvis ring fractures. Materials and methods. In the course of the present review, a total of 23 patients were assessed, who had been treated surgically for a pelvic fracture and who were followed-up thoroughly for at least three years. Results. Patients' average age at the time of the accident was 32 (13-59) and males outnumbered females(19:4). The mist frequent fracture type was type C3 (7 cases). On 7 occasions, the fracture line ran along the transacroiliac axis. Related lesions were found in 21 out of the 23 patients and most of them involved fractures of some small bone in the lower limb (14 cases). The most usual treatment in the emergency setting was immobilization with an external fixation device. Definitive treatment involved preferably a posterior approach. The mean follow-up period was 5.74 years (3.14-10.02). 48% of patients present with some degree of residual limping and 8 patients have pain. Four patients have lower-limb dysmetria greater than 2 cm. Three have been left with pelvic obliquity. The radiological results reveal that 18 patients achieved a perfect reduction in the anterior part of their pelvis ring and 13 in the posterior part. In 5 cases an integration disorder was detected and in 86.4% of patients radiological signs have been detected that are compatible with the diagnosis of osteoarthritis. Conclusions. Even if a correct surgical reduction of the bone fragments can be achieved, the feeling of pain and the persistence of dysmetria and limping are among the most frequent sequelae of these types of lesions. In spite of the percentages presented, probably because of the small number of cases in the series, it was not possible identify some of the factors of the initial condition or the characteristics of the surgical result related to the final result of the surgical treatment of pelvic fractures
