Introducción: Existen más de 20 técnicas diferentes para corregir la discrepancia de miembros inferiores. El método que aquí se evalúa se basa en una clavija fija posicionada en el ala ilíaca asociada a un “calibre” móvil, con otra clavija con la que se marca la referencia en el trocánter mayor. Objetivo: Evaluar la confiabilidad de este dispositivo de medición usado durante la artroplastia total de cadera para restaurar la longitud del miembro inferior y el offset femoral. Materiales y Métodos: Se formaron dos grupos: grupo A con pacientes en quienes no se había usado el dispositivo y grupo B con pacientes en quienes sí se había usado el dispositivo. Se realizaron las mediciones en la radiografía panorámica de pelvis obtenida con el paciente de pie, antes de la cirugía y 3 meses después. Resultados: Se obtuvo una muestra de 80 pacientes (40 por grupo). Se logró corregir la discrepancia de la longitud de los miembros, pero no se hallaron diferencias estadísticamente significativas en la corrección promedio, entre ambos grupos (p = 0,07). Sin embargo, al analizar la varianza en la corrección de la discrepancia de la longitud de cada grupo se obtuvo una diferencia estadísticamente significativa (p

Introducción: En los últimos años, la introducción de diversas técnicas, el instrumental quirúrgico y las competencias del cirujano han contribuido a disminuir las complicaciones tempranas que pueden sobrevenir luego de una artroplastia de cadera. Las complicaciones más frecuentes son: el aflojamiento femoral, la trombosis venosa profunda y la luxación. Objetivos: Evaluar la tasa de complicaciones intraoperatorias y durante los primeros 12 meses luego de una artroplastia de cadera por vía anterolateral directa; y comparar los resultados con la serie publicada en 2007. Materiales y Métodos: Estudio de cohorte retrospectivo que incluyó a pacientes operados por artrosis primaria de cadera en 2 instituciones, divididos en: grupo I (468 pacientes operados entre junio de 1999 y junio de 2003) y grupo II (344 pacientes operados entre enero de 2018 y enero de 2020). Resultados: La tasa global de complicaciones en la nueva serie fue del 4,7%. La trombosis venosa profunda fue la complicación que más se repitió, no hubo episodios de luxación. El empleo de cabezas de 22 mm de diámetro se asoció con un riesgo de luxación más alto que con cabezas más grandes (OR = 6,7; IC95% 1,2-78,2). Conclusiones: La artroplastia total de cadera con abordaje anterolateral transglúteo directo causó una baja tasa global de complicaciones dentro del primer año de la cirugía. Las complicaciones se redujeron casi a la mitad en las cirugías realizadas entre 2018 y 2020, con respecto a la serie anterior, fundamentalmente a expensas de la luxación.

La artroplastia total de cadera es una cirugía eficaz para tratar la artrosis. Con el aumento de la necesidad de una mejor calidad de vida, este procedimiento se está realizando en pacientes más jóvenes. Pero, con la mayor expectativa de vida, también crece la demanda de múltiples cirugías de revisión para el mismo paciente. Esto plantea desafíos técnicos debido a la pérdida de hueso. Existe una necesidad creciente de identificar implantes duraderos y altamente funcionales que sean adecuados para la revisión futura. Aunque los vástagos femorales cementados eran la opción principal en el pasado, los vástagos femorales no cementados han logrado una fijación a largo plazo y excelentes resultados. Sin embargo, aún se pueden mejorar algunos problemas relacionados con la fijación. Los vástagos femorales cortos han sido desarrollados para abordar algunos de estos desafíos, mientras se mantienen los buenos resultados obtenidos con los vástagos convencionales. En este artículo, se analiza la experiencia tras 10 años de uso de vástagos femorales cortos en cirugías de cadera en pacientes jóvenes. Se comparan los resultados biomecánicos y la preservación ósea femoral, se reportan los resultados posoperatorios en relación con el regreso al deporte, y se evalúan las complicaciones relacionadas con su uso. El empleo de vástagos cortos en cirugía primaria de cadera brinda múltiples ventajas. La indicación de este tipo de implante está justificada en pacientes jóvenes y activos, con el objetivo de reproducir los resultados de los implantes convencionales con un menor consumo de hueso y la posibilidad de una revisión futura.

Introducción: El objetivo de este estudio fue analizar los resultados clínicos, radiográficos y funcionales en pacientes

Introducción: La enfermedad de Paget es un trastorno metabólico de etiología desconocida, secundario a un incremento en la función de los osteoclastos y la consecuente respuesta de los osteoblastos a la formación exagerada de hueso. Compromete con mayor frecuencia el fémur proximal y, a menudo, se diagnostica incidentalmente. Se presenta el caso de una mujer con antecedente de enfermedad de Paget y pseudoartrosis de cadera izquierda, con indicaciones de prótesis total de cadera izquierda y un episodio único de luxación, sin complicaciones posteriores y una adecuada evolución. Conclusión: El manejo quirúrgico en casos de fractura de cadera permite restablecer la marcha y mejorar la calidad de vida de los pacientes con enfermedad de Paget. A pesar de ser una patología que dificulta el manejo de los pacientes, la enfermedad de Paget no es una contraindicación para la artroplastia total de cadera y permite mejorar el dolor y recuperar la funcionalidad

En este estudio retrospectivo fueron seleccionados 184 pacientes sometidos a artroplastía total primaria de cadera. 95 fueron abordados por la región ántero lateral y 89 por la posterior, desde junio de 1993 a junio de 1997. Los eventos evaluados fueron parámetros perioperatorios (tiempo quirúrgico, de internación hospitalaria, e intervalo entre cirugia y el alta, hemorragia y necesidad de transfusión sanguínea), y complicaciones (trombosis venosas proftindas, embolia pulnionar. lesión de nervio periférico, inestabilidad de la prótesis y otras). Los dos grupos no di ferian en cuanto a las indicaciones preoperalorias. Los pacientes de abordaje posterior tuvieron un tiempo quirúrgico reducido (p < 0,001). además de presentar menores hemorragias transoperatonas (p < 0.05) y necesidad de transfusión post operatoria (p < 0.001). Los grupos no diferían en cuanto a los demás parámetros y complicaciones, que tuvieron baja frecuencia. El abordaje posterior ha sido realizado con éxito por el Grupo de Cirugia de Cadera del Hospital de Clínicas de Porto Alegre, siendo una excelente opción de acceso quirúrgico para artropl astía total de cadera.

Introducción: La mala alineación de los tallos femorales no cementados sigue siendo un tema controvertido. Algunos autores han comunicado una inadecuada osteointegración y hundimiento en los tallos en varo y otros no encontraron dichos efectos adversos, pese a la incorrecta alineación. Los objetivos de este estudio fueron determinar la prevalencia de tallos no cementados con cobertura total de hidroxiapatita en deseje coronal y mostrar los resultados clínico-radiográficos a largo plazo. Materiales y Métodos: Estudio retrospectivo entre 2006 y 2009. Se analizaron 220 reemplazos totales de cadera primarios con tallos no cementados con cobertura completa de hidroxiapatita. La alineación coronal fue analizada con radiografías anteroposteriores de ambas caderas en 10° de rotación interna. Se registraron datos, como osteointegración, hundimiento, osteólisis femoral proximal e hipertrofia cortical. Para el análisis clínico se utilizó el Harris Hip Score. El análisis de supervivencia contempló la necesidad de revisión por cualquier causa. Resultados: La prevalencia de tallos en deseje fue del 32,3%, con mayoría de implantes en varo (73,3%). El Harris Hip Score tuvo un incremento estadísticamente significativo (41,05 ± 6,5 vs. 90,05 ± 2,5; p

Las fracturas por insuficiencia subcondral son una causa poco frecuente de cadera dolorosa. A diferencia de las fracturas traumáticas agudas, las fracturas por insuficiencia del acetábulo son menos frecuentes que las femorales. Ocurren habitualmente en mujeres posmenopáusicas con comorbilidades. Su diagnóstico inicial suele ser dificultoso y la sospecha clínica es de gran importancia. La resonancia magnética es una herramienta fundamental para detectar este cuadro. Subestimar estas lesiones puede llevar al desarrollo de una artrosis rápidamente progresiva y al reemplazo articular como desenlace. Se presenta el caso de una paciente de 68 años con una fractura por insuficiencia subcondral del acetábulo a quien se le indicó una artroplastia total de cadera no cementada.

Introduction: The aim of this study was to evaluate the efficacy of aspirin versus low molecular weight heparins (LMWH) for the prophylaxis of venous thromboembolism (VTE), deep vein thrombosis (DVT) and pulmonary embolism (PE) in patients undergoing total knee arthroplasty (TKA) and/or total hip arthroplasty (THA)., Materials and Methods: Systematic review and meta-analysis. Sixteen studies were selected. The risk of VTE, DVT and PE were analysed. Mortality, risk of bleeding and surgical wound complications was also analysed., Results: 248,461 patients were included. 176,406 patients with thromboprophylaxis with LMWH and 72,055 patients with aspirin thromboprophylaxis. There were no significant differences in the risk of VTE (OR=0.93; 95% CI: 0.69-1.26; p=0.64), DVT (OR=0.72; 95% CI: 0.43-1.20; p=0.21) or PE (OR=1.13; 95% CI: 0.86-1.49; p=0.38) between both groups. No significant differences were found in mortality (p=0.30), bleeding (p=0.22), or complications in the surgical wound (p=0.85) between both groups. These same findings were found in the sub-analysis of only randomised clinical trials (p>0.05)., Conclusions: No increased risk of PE, DVT, or VTE was found among patients with aspirin thromboprophylaxis versus patients with LMWH thromboprophylaxis. There was also no greater mortality, greater bleeding, or greater complications in the surgical wound found among patients with aspirin thromboprophylaxis versus patients with LMWH thromboprophylaxis., (Copyright © 2023 SECOT.

Introduction and Objective: Hip arthroplasty represents a significant advancement in the treatment of refractory chronic joint pain, improving quality of life and functionality. The objective of this study is to identify the risk factors associated with local and systemic complications in patients treated with total hip arthroplasty., Methods: Observational, analytical, retrospective cohort study, which included 304 participants treated with total hip replacement. Comparison of variables between two groups was performed; 38 participants in the group with complications and 266 participants in the group without complications., Results: The mean age in the complication group was 66 years (SD 18.7) and in the uncomplicated group it was 67,1 years (SD 15.1) (p 0,686). Female sex was observed in 73.3% of the group with complications and 65% in the group without complications. (p 0.292). Risk factors were: hip fracture as an indication for arthroplasty RR 1.33 [95% CI 1.004;1.775 p 0.047], coronary heart disease RR 1.31 [95% CI 1.067;1.616 p 0.010] and surgical bleeding equal to or greater than 400 cc RR 1.11 [95% CI 1.012;1.218 p 0.028]., Conclusions: The risk factors for complications in total hip arthroplasty were: hip fracture as the indication for arthroplasty, coronary artery disease, and surgical bleeding equal to or greater than 400 cc., (Copyright © 2024 SECOT.

Introduction: Total hip arthroplasty (THA) in patients with residual poliomyelitis (RP) is a surgical challenge. Dysplastic morphology, osteoporosis and gluteal weakness hinder orientation, increase fracture risk and reduce implant stability. The aim of this study is to describe a series of patients with RP treated by THA., Material and Methods: Retrospective descriptive study of patients with RP treated with THA between 1999 and 2021 in a tertiary hospital, with clinical and radiological follow-up and functional and complication evaluation until present or death, with a minimum of 12 months., Results: Sixteen patients underwent surgery, with 13 THA implanted in the paretic limb, 6 for fracture and 7 for osteoarthritis, while the remaining 3 were implanted in the contralateral limb. Four dual mobility cups were implanted as an antiluxation measure. At 1 year postoperatively, 11 had complete range of motion with no increase in Trendelenburg cases. The Harris hip score (HHS) improved 32.1 points, the visual analogue scale (VAS) 5.25 points, and the Merlé-d'Augbiné-Poste scale 6 points. The length discrepancy correction was 13.77mm. Median follow-up was 3.5 years (1-24). Two cases were revised for polyethylene wear and two for instability, with no infections, periprosthetic fractures, or cup or stem loosening., Conclusions: THA in patients with RP allows improvement of the clinico-functional situation with an acceptable complication rate. The risk of dislocation could be minimised with dual mobility cups., (Copyright © 2023 SECOT. Publicado por Elsevier España, S.L.U. All rights reserved.)

Hace 50 años, Sir John Charnley introdujo la era del reemplazo total de cadera. Sus innovaciones en la fijación de la prótesis con polimetilmetacrilato, el par de fricción de metal/ polietileno, la instrumentación estandarizada y los quirófanos con aire purificado, revolucionaron los intentos previos a reemplazar caderas con artrosis. En Estados Unidos, los principios y la prótesis de Charnley fueron adoptados, investigados y modificados tal como lo ha sido en otros países. Sin embargo, su técnica y conceptos básicos siguen estando vigentes y el reemplazo total de cadera es ampliamente considerado uno de los procedimientos quirúrgicos más exitosos en la cirugía ortopédica. Más de 400.000 reemplazos de cadera son realizados anualmente en los Estados Unidos.

Introducción Desde hace tiempo se ha comenzado a prestar atención a la satisfacción del paciente luego de una artroplastia de cadera o rodilla. Para esto se han confeccionado diferentes sistemas de encuestas para medir el impacto de la cirugía en la vida del paciente. El objetivo de este trabajo fue mediante una encuesta evaluar la satisfacción luego de un RTR o RTC. Material y Métodos Analizamos 59 RTC primarios en 59 pacientes con un promedio de edad de 64,4 años y un seguimiento promedio de 3,4años y 47 RTR unilaterales, con un promedio de edad de 62,2 años y un seguimiento promedio de 3,2 años. A todos se les entregó una encuesta para que completaran en sus hogares. Como mínimo estos pacientes tenían un año de seguimiento. Resultados Los RTC estuvieron conformes con la cirugía en un 98,3%, mientras que los RTR lo estuvieron en un 100%. En cuanto al cumplimiento de las expectativas el 95% de los RTC estuvieron absolutamente conformes y los RTR lo estuvieron en el 86,6%. El puntaje promedio de la encuesta para los RTC fue de 6,2 puntos y para los RTR fue de 12 puntos. Conclusión Entre el 81 y 89% de los pacientes están conformes luego de un RTC, mientras que entre el 83 y 96% lo estará luego de un RTR. Las expectativas preoperatorias a una artroplastia se focalizan en el alivio del dolor, la mejoría funcional y la independencia física. Si bien en nuestra serie encontramos aceptables niveles de satisfacción, creemos que el cirujano debe ser prudente en el pre operatorio, para no crear falsas expectativas, en cuanto a los resultados pop, para de esta manera mejorar la satisfacción de los pacientes luego de la intervención.

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., (Copyright © 2022 SECOT.

Resumen: Objetivo: Determinar el estado de salud general percibida por los pacientes sometidos a artroplastia total de cadera con mini-vástago. Material y Método: Se ha administrado el cuestionario de salud SF-36 para evaluar el estado de salud percibido por 13 pacientes varones con una edad media de 46,62 (34-53) años en los que seimplantó una artroplastia total de cadera no cementada tipo MiniHip® (CorinMedical) tras un seguimiento medio de 23,2 (12-47) meses. Los resultados obtenidos se compararon con los valores de referencia de la población española en varones de 45 a 54 año. Resultados: Se hallaron diferencias en aspectos como rol físico y emocional, función física, función social y dolor; mientras que en el resto de los ítems la puntuación fue similar a la de la población de referencia. Discusión: Existe la necesidad de conocer en qué grado afectan nuestras intervenciones a la calidad de vida del paciente y la manera en que es percibida por él mismo para complementar los resultados de nuestras intervenciones. Conclusión: Es necesaria una nueva perspectiva para la valoración funcional y de calidad de vida de los pacientes jóvenes sometidos a una artroplastia total de cadera. Abstract: Objective: To determine the general health status perceived by patients undergoing total hip arthroplasty with mini-stem. Material and Methods: Health questionnaire SF-36 has been used to assess health perceived by 13 male patients with a mean age of 46.62 (34-53) years after the implantation of an uncemented, MiniHip® (CorinMedical) total hip arthroplasty, after a mean follow up of 23.2 (12-47) months. Results were compared with the reference values of Spanish men population from 45 to 54 years. Results: Differences were found in areas such as physical and emotional role, physical function, social function and pain; while scores of the remaining items were similar to the population of reference. Discussion: It is important to know how our surgical actions affect the quality of life of patients and how it is perceived by them to complement the results of our surgeries.

Se presenta el caso clínico de una paciente de 52 años con diagnóstico de tuberculosis de cadera derecha a quien en 1991 se le instala prótesis de Titanio. Once años después presenta aumento de volumen de la extremidad inferior y masa palpable en zona inguinal. Fue estudiada con ultrasonografía y tomografía computada cuyos hallazgos se describen. Se planteó como diagnóstico diferencial principal un sarcoma en compartimiento iliopsoas por lo cual se realiza biopsia bajo ultrasonografía que demostró metalosis por Titanio diagnóstico que debe ser considerado en pacientes con masa inguinal y prótesis de cadera. Se reseca la lesión, la cual recidiva, requiriendo recambio articularAn 52 year-old female patient with right hip joint Tuberculosis, received a Titanium total joint arthroplasty in 1991. Eleven years later, she presented low extremity swelling and inguinal mass, which was studied with ultrasound and computed tomography. The main differential diagnosis was an iliopsoas sarcoma, so an ultrasound-guided biopsy was performed. The result was Titanium particle debris. The lesion was removed, but it recurred, so that joint replacement was required. Joint Titanium particle wear debris a condition due to particle releaseis as an arthroplasty complication. When its clinical manifestation is a pelvic mass, the main differential diagnoses include tumors and granulomatous disease. Both clinical manifestations and the radiology are variable. This pathology in patient with hip joint Titanium arthroplasty must be consided

Background and Objective: Pelvic tilt influences the relative position between total hip arthroplasty (THA) components. Changes in lumbar spine over time may affect clinical and radiological outcomes of THA during follow-up. We assessed the evolution of pelvic tilt and cup position after THA for a minimum follow-up of five years and the possible appearance of complications., Material and Methods: This retrospective study includes 48 patients operated between 2008 and 2012. Clinical data, complication and radiological analysis included sacro-femoral-pubic and acetabular abduction angles on the anteroposterior pelvic view; and cup anteversion angle on the lateral cross-table hip view according to Woo and Morrey. All assessments were done pre-operatively and at 6 weeks, one, two and five years post-operatively., Results: Mean sacro-femoral-pubic decreased from 60.6∘ preoperatively to 58.8∘ at five years (p > .05), more in females (from 63.3 to 59.3) than males (58.7 to 58.3). Acetabular abduction increased from 47.3 at six-week postoperatively to 48.2 at five years (p > .05) and acetabular anteversion varied from 24.3∘ to 36.1∘ (p < .04). There were four dislocations: one late recurrent dislocation which required cup revision., Conclusion: Despite the sacro-femoral-pubic angle tendency to decrease and anteversion tendency to increase after five years, larger studies with longer follow-up are needed to confirm the potential increasing in long term complications., (Copyright © 2021 SECOT.

Introduction: The elderly population candidate for total hip arthroplasty (THA) is increasing exponentially in developed countries, due to the high prevalence of osteoarthritis (OA). The objective is to identify the overall survival in patients over 85 years with primary OA who underwent THA., Material and Methods: Retrospective observational study in patients over 85 years with primary hip OA undergoing THA between 2012 and 2019. Demographic, clinical, comorbidity, complications, functionality and pain variables were collected. A descriptive analysis was performed, survival was estimated with the Kaplan-Meier method and the differences in pain and functionality before and after surgery with the McNemar-Bowker test., Results: We included 66 patients, 40 women and 26 men with a mean age of 87.22 years, of whom 15 had high comorbidity (Charlson>2). Only 14 patients presented complications in the postoperative period, the most frequent was confusional syndrome (5); and the most serious was a death (1), with a median hospital stay of 8 days. Two cases of dislocation were detected over a mean follow-up of 3.61 years, without requiring revision surgery. Improvement of pain was evident after surgery (p<.0001). The median overall survival is 6.77 years, with no difference in survival adjusted by the Charlson index (p=.75) or by ASA anaesthetic group (p=.23)., Conclusions: With good patient selection, THA is a good option for patients over 85 years of age with functional limitations or pain due to OA., (Copyright © 2020 SECOT.

Background and Objectives: There are no randomized prospective studies that evaluate sports activity after total hip arthroplasty (THA). The objective of this study is to assess the level and type of sports activity in patients undergoing THA and to assess the recommendations given by physicians., Materials and Methods: We performed a descriptive study that analyzes 46 patients (the average age was 41 years, range 37 - 48) under 50 years of age who underwent THA (58 hips) in our center. The average follow-up was 7.5 (1 - 11) years. Age, sex, sports activity according to the UCLA scale, sports activities practiced before and after the intervention, complications and recommendations given by doctors were evaluated., Results: The average time to resume sport activity after the surgery was 5 (3-10) months. There were no differences in the UCLA scale before and after the operation (P> 0.05). The most practiced sport before the surgery was swimming (17%). The 31% of patients did not receive advice from their physician and the 65.2% were dissuaded from playing sports after ATC. The recommended sports were swimming (44%) and the static bicycle (17.5%), correlating with the most practiced sports after the operation., Conclusion: The patients modified their sport activity after having undergone a total hip arthroplasty. The surgery and the physician's advice were the ones that influenced the choice of the sports activity performed after being operated on., (Copyright © 2020 SECOT.

Background: Implementation of Patient Blood Management programs remain variable in Europe, and even in centres with well-established PBM programs variability exists in transfusion practices., Objectives and Methods: We conducted a survey in order to assess current practice in perioperative Patient Blood Management in patients undergoing total hip and knee replacement among researchers involved in POWER.2 Study in Spain (an observational prospective study evaluating enhanced recovery pathways in orthopaedic surgery)., Results: A total of 322 responses were obtained (37.8%). Half of responders check Haemoglobin levels in patients at least 4 weeks before surgery; 35% treat all anaemic patients, although 99.7% consider detection and treatment of preoperative anaemia could influence the postoperative outcomes. Lack of infrastructure (76%) and lack of time (51%) are the main stated reasons not to treat anaemic patients. Iron status is routinely checked by 19% before surgery, and 36% evaluate it solely in the anaemic patient. Hb<9.9 g/dl is the threshold to delay surgery for 61% of clinicians, and 22% would consider transfusing preoperatively clinically stable patients without active bleeding. The threshold to transfuse patients without cardiovascular disease is 8 g/dl for 43%, and 7 g/dl for 34% of the responders; 75% of clinicians consider they use "restrictive thresholds", and 90% follow the single unit transfusion policy., Conclusions: The results of our survey show variability in clinical practice in Patient Blood Management in major orthopaedic surgery, despite being the surgery with the greatest tradition in these programs., (Copyright © 2020 Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor.

Objective: To determine the incidence of dislocation after primary total hip arthroplasty using a posterior approach with repair of capsule and transosseous external rotators., Material and Method: Historical cohort study between January 2009 and December 2015 of all the cases of dislocation of primary total hip arthroplasty operated using a posterior approach with repair of capsule and transosseous external rotators. Demographic and clinical data concerning the patient, surgery and dislocation were collected and analyzed. A descriptive analysis and a study of survival and risk function were performed by Kaplan Meier's method considering the appearance of a hip dislocation as the final event., Results: The incidence of dislocation in our study was 1.2% (23 patients). In our study, the highest probability of dislocation occurred in the first 120 days. Forty-three point 5percent of the dislocated patients needed revision surgery., Conclusions: Capsular repair and transosseous reattachment of the external rotators can help to reduce the incidence of dislocation in patients undergoing primary total hip arthroplasty through a posterior approach., (Copyright © 2018 SECOT.

Introduction: Blood cobalt (Co) and chromium (Cr) ion levels have been used as surveillance tools for adverse reaction to metal debris in metal-on-metal (MoM) hip arthroplasty. The aim of our study was to present serial 7-13 year blood Co and Cr levels in a cohort of MoM total hip arthroplasties in asymptomatic patients., Material and Methods: A total of 52 MoM surface total hip arthroplasties were included in this study with data collected prospectively. Annual follow-up with blood Co and Cr measurements was performed. Revision surgery was necessary for 16 patients and therefore they dropped out of the study. The metal ion levels were analyzed separately in 31 asymptomatic patients., Results: High Cr or Co levels were not found continuously in any of the asymptomatic patients. The median Cr in blood was maintained between 1.3 and 5.4μg/L and that of Co between 0.5 and 1.2μg/L. After 7 years, there was no significant change in Co and Cr values., Conclusion: In the medium term and in asymptomatic patients, the metallic blood levels remained unchanged; therefore, it does not seem appropriate to repeat these tests on a permanent basis in annual controls., (Copyright © 2018 SECOT.

Se presenta el caso clínico de una paciente de 52 años con diagnóstico de tuberculosis de cadera derecha a quien en 1991 se le instala prótesis de Titanio. Once años después presenta aumento de volumen de la extremidad inferior y masa palpable en zona inguinal. Fue estudiada con ultrasonografía y tomografía computada cuyos hallazgos se describen. Se planteó como diagnóstico diferencial principal un sarcoma en compartimiento iliopsoas por lo cual se realiza biopsia bajo ultrasonografía que demostró metalosis por Titanio diagnóstico que debe ser considerado en pacientes con masa inguinal y prótesis de cadera. Se reseca la lesión, la cual recidiva, requiriendo recambio articular

Antecedentes: El sangrado secundario es una de las principales causas de morbilidad después de la cirugía. El etamsilato se ha utilizado con buenos resultados para disminuir el sangrado en diversas patologías, como metrorragias, sangrado intraventricular, prostatectomías, cirugías de catarata y amigdalectomías. El objetivo de este estudio fue evaluar la efectividad del etamsilato para disminuir el sangrado en la cirugía de reemplazo total de cadera., Método: La población se dividió en dos grupos. En el grupo control se realizó la hemostasia de manera convencional; en el grupo experimental se administró etamsilato., Resultados: Se incluyeron 34 pacientes, de los cuales 17 fueron aleatorizados al grupo de etamsilato y 17 al grupo control. No hubo diferencias en las características de la población entre los dos grupos. Al comparar los valores de hemoglobina preoperatoria y a las 24, 48 y 72 horas posquirúrgicas entre ambos grupos, no se encontraron diferencias estadísticamente significativas. Tampoco hubo diferencia en el hematocrito ni en la cuantificación del gasto por drenaje a las 24 y 48 horas. Hubo tres pacientes transfundidos en el grupo de etamsilato y siete en el grupo de control, lo cual no difirió significativamente (p = 0.62)., Conclusión: En este estudio no se demostró un efecto sobre la reducción de la hemorragia en pacientes sometidos a reemplazo total de cadera con el uso de etamsilato., Background: Secondary bleeding is one of the leading causes of morbidity after the surgery. Ethamsylate has been used with good results to decrease bleeding in various pathologies such as metrorrhagia, intraventricular bleeding, prostatectomies, cataract surgeries and tonsillectomies. The objective of this study was to evaluate the effectiveness of the hemostatic agent ethamsylate to decrease bleeding in total hip replacement surgery., Method: The population were divided into two groups, in the control group was performed the hemostasis conventionally; in the experimental group ethamsylate was administered., Results: A total of 34 patients were included, of whom 17 were randomized to the group of ethamsylate and 17 randomized to the control group. There were no differences in the characteristics of the population between the two groups. Comparing preoperative hemoglobin levels and at 24, 48 and 72 postsurgical hours between the control group and ethamsylate group there was no statistically significant difference. There was also no difference in the levels of hematocrit. In the quantification of expenditure by the drainage there was no difference between the groups at 24 and 48 hours. There were three patients transfused in the ethamsylate group and seven in the control group, which did not differ significantly (p = 0.62)., Conclusion: An effect on the reduction of bleeding in patients undergoing total hip replacement with the use of hemostatic agent ethamsylate was not demonstrated in this study., (Copyright: © 2018 SecretarÍa de Salud.)

Objective: To study the efficacy of tranexamic acid to decrease perioperative bleeding in patients who have undergone a total hip arthroplasty operation and to evaluate drug safety., Material and Methods: Observational, prospective, controlled and randomized study on the efficacy of tranexamic acid as a method to reduce bleeding in primary hip replacement surgery. We included 134 patients operated during 2014 in our centre, who were divided into 2 groups according to whether or not they had received tranexamic acid. The main study variables were haemoglobin and haematocrit levels, the amount of blood collected from the post-operative drain in the first 12, 24 and 48hours and transfusion requirements., Results: Post-operative haemoglobin and haematocrit levels were statistically higher (P<.001) in the group with treatment. During the first 48hours bleeding values from the group that did not receive TAX were higher compared to patients treated with tranexamic acid. Statistically significant differences (P=.001) were found as to the need for transfusion according to group, more transfusions were performed in the cohort that had not received tranexamic acid: 25.37% compared to 4.48% for the group with tranexamic acid. No adverse events related to administration of tranexamic acid were recorded., Conclusions: Administration of tranexamic acid has proved to be an effective and safe method to reduce peri-operative bleeding in patients who underwent total hip arthroplasty and avoids allogenic blood transfusion. Therefore, tranexamic acid treatment could entail a financial saving for the healthcare system and expose the patient to less risk., (Copyright © 2017 SECOT. Publicado por Elsevier España, S.L.U.

Purpose: To determine the cost reduction and complication rates of using an enhanced recovery pathway (Fast-track) when compared to traditional recovery in primary total hip replacement (THR) and total knee replacement (TKR), as well as to determine if there were significant differences in complication rates., Material and Methods: Retrospective review of 100 primary total arthroplasties using the Fast-track recovery system and another 100 using conventional recovery. Gender, Charlston comorbidity index, ASA score, length of stay and early complications were measured, as well in-hospital complications and those in the first six months, re-admissions and transfusion rates. The total and daily cost of stay was determined and the cost reduction was calculated based on the reduction in the length of stay found between the groups., Results: Both groups where comparable as regards age, gender, ASA score, and Charlston index. The mean reduction in length of stay was 4.5 days for TKR and 2.1 days for THR. The calculated cost reduction was 1266 euros for TKR and 583 euros for THR. There were no statistically significant differences between groups regarding in-hospital complications, transfusion requirements, re-admissions and complication rates in the first six months., Discussion: There are few publications in the literature reviewed that analyse the cost implications of using fast-track recovery protocols in arthroplasty. Several published series comparing recovery protocols found no significant differences in complication rates either. The use of a fast-track recovery protocol resulted in a significant cost reduction of 1266 euros for the TKR group and 583 for the THR group, without affecting complication rates., (Copyright © 2016 SECOT.

Fast-track surgery, or enhanced recovery, has appeared in the last 20 years or so as a combination of the optimisation of clinical protocols and organisational processes, pursuing the reduction in surgical stress with the aim of reducing peri-operative comorbidities, convalescence time, and functional recovery, resulting in a reduction in admission time. After a review of the European literature available on this subject, this article attempts to present an update. It highlights its interest and origins, basically being set out as a response to the question: 'Why is this patient in Hospital today?' It also attempts to summarise the essence of such programmes: the search for immediate post-surgical mobilisation, being supported in a multidisciplinary approach. This includes a multimodal intervention and analgesia, a limitation in the use of opiates, and the active participation by the patients in their own recovery. Furthermore, mention is made of the initiatives by European State organisation as a boost to enhanced recovery programmes in their respective countries, as is the case in Denmark, France, and the United Kingdom. The clinical outcomes published up to September 2015 have been reviewed. A subsequent decrease in mean hospital stay is observed in 11 studies, achieving patient satisfaction, low complication rates, a reduction in the transfusion rates, and with no apparent increase in re-admissions. Mention is also made of the financial consequences, and how to implement these protocols. As a conclusion, an analysis is made of the future challenges fast-track surgery, such as the possibility of moving towards outpatient surgery, or the obtaining of a surgery 'with no risk or pain' in general, for which there are other still open lines of work., (Copyright © 2017 SECOT.

Objectives: To evaluate risk factors for dislocation after primary total hip arthroplasty (THA), and its functional outcomes., Material and Methods: A retrospective study was conducted on 22 cases with dislocation and 431 controls without dislocation, all performed with lateral access. The data were collected prospectively with a minimum follow-up of 5 years. Patient related factors, from primary surgery, and position of components on simple radiographs were analyzed. Harris and Merle D'Aubigné hip scores, and short Womac questionnaire were used., Results: Demographic, patient-related or surgical technique factors were not risk predictors of dislocation. With regard to position of components, an acetabular abduction >50° (p = 0.003) and anteversion lower or higher than 10°- 20° (p = 0.044) were risk factors. Controls and dislocation treated conservatively had similar outcomes, and in both were better than in those treated with surgical revision (p = 0.03)., Discussion: Factors relating to the patient and soft tissues status may influence the stability of the arthroplasty, but malposition of the acetabular component seems to be the most important and common risk factor for dislocation., (Copyright © 2014.

Many postoperative complications have been described after a total hip arthroplasty, with early and acute, as well as late, complications being reported. Two cases of compartment syndrome of the buttock are described following a hybrid total hip arthroplasty (cemented stem and press-fit and screwed acetabulum) performed on 2 patients of 60 and 68 years old, both diagnosed and treated 24-48 hours after the surgery. Both cases had a primary prosthesis with no previous significant pathological findings. This condition is still rare, and few cases have been described at the medical literature., (Copyright © 2012 SECOT. Published by Elsevier Espana. All rights reserved.)
