ABSTRACT

Abstract Objective The present study aims to evaluate the treatment of hip wave lesion using reverse microfracture, which is a simple and cheap surgical procedure. Methods We retrospectively analyzed 19 patients with acetabular wave lesion treated with reverse microfracture. The patients were assessed by magnetic nuclear resonance imaging (MRI) at the time of diagnosis and 6 months after the surgery and functionally evaluated using the Harris Hip Score (HHS) and the visual analogue scale (VAS) for pain in the preoperative period, and 3 and 6 months after the surgery. Results The statistical data showed a significant improvement in HHS and VAS 6 months after the surgery. Six months after the surgery, the MRI revealed that the area subjected to reverse microfracture presented cartilage with the same visual characteristics observed in areas with no chondral injury. Conclusion We conclude that the reverse microfracture proved to be an effective, reproducible method for the treatment of wave lesion.


Resumo Objetivo Avaliar o tratamento desta lesão, através da microfratura reversa, que é um procedimento simples e sem aumento de insumos na cirurgia. Métodos Foram analisados retrospectivamente 19 pacientes submetidos a tratamento da lesão em onda no acetábulo, através da microfratura reversa. Utilizamos a ressonância nuclear magnética (RNM) no momento do diagnóstico e 6 meses após a cirurgia, avaliação funcional pelo Harris Hip Score (HHS) e escala visual e analógica (EVA) da dor no pré-operatório, e 3 e 6 meses após a cirurgia. Resultadoos dados estatísticos mostraram melhora significativa do HHS e EVA da dor após 6 meses da cirurgia. A RNM após 6 meses da cirurgia mostrou que na área que foi submetida à microfratura reversa, a cartilagem se apresentou com as mesmas características visuais que nas áreas sem lesão condral. Conclusão Concluímos que a microfratura reversa se mostrou eficaz e reprodutível no tratamento da lesão em onda.

ABSTRACT

Introducción: La luxación de la prótesis total de cadera puede afectar los resultados del implante, la calidad de vida del paciente, y el costo del proceso. Su etiología es multifactorial. Objetivos: Identificar posibles factores de riesgo relacionados con la aparición de luxación en prótesis total de cadera en una serie de casos. Métodos: En una serie de 2732 prótesis total de cadera, en la que hubo 92 luxaciones (3,4 por ciento), se compararon factores relacionados con el paciente, el implante, y la técnica quirúrgica uilizada en el Hospital La Paz-IDIPaz de Madrid entre los años 2000 y 2016. Se utilizó el análisis de regresión para la significación de dichos factores. Resultados: De las 92 luxaciones, 62 fueron tratadas de manera conservadora (67,4 por ciento) y 30 pacientes precisaron de cirugía de revisión (32,6 por ciento). El estudio multivariado mostró significación estadística en los siguientes factores de riesgo: estado de la columna lumbar (p < 0,001), y una pobre reconstrucción del centro de rotación de la cadera (p= 0,035), y cúpulas posicionadas fuera de las ventanas de Lewinnek (p < 0,001) y del mecanismo abductor (p < 0,001) en relación con la técnica quirúrgica. No hubo factores significativos en relación con el tipo de implante, diámetro de la cabeza femoral o par de fricción. Conclusiones: La patología lumbar aumenta el riesgo de luxación en la prótesis total de cadera. Una adecuada reconstrucción de la cadera, que incluya la posición de la cúpula y el centro de rotación de la cadera, así como del mecanismo abductor ayudaría a mejorar la tasa de inestabilidad(AU)


Introduction: The dislocation of the total hip replacement can affect the results of the implant, the quality of life of the patient, and the cost of the process. Its etiology is multifactorial. Objectives: To identify possible risk factors related to the appearance of dislocation in total hip replacement in a series of cases. Methods: In a series of 2732 total hip prostheses, in which there were 92 dislocations (3.4percent), factors related to the patient, the implant, and the surgical technique used at La Paz-IDIPaz Hospital in Madrid were compared, from 2000 to 2016. Regression analysis was used for the significance of these factors. Results: Out of 92 dislocations, 62 were treated conservatively (67.4 percent) and 30 patients required revision surgery (32.6 pecent). The multivariate study showed statistical significance in the following risk factors: state of the lumbar spine (p <0.001), and poor reconstruction of the center of rotation of the hip (p = 0.035), and domes positioned outside Lewinnek windows (p <0.001) and the abductor mechanism (p <0.001) in relation to the surgical technique. There were no significant factors in relation to the type of implant, diameter of the femoral head or friction torque. Conclusions: Lumbar pathology increases the risk of dislocation in total hip replacement. Proper hip reconstruction, including the position of the dome and the center of rotation of the hip, as well as the abductor mechanism, would help to improve the rate of instability(AU)

ABSTRACT

La osteoartritis secundaria a displasia o luxación congénita de cadera conlleva grandes dificultades para el cirujano que reconstruye la cadera. Los casos con escasa deformidad no difieren prácticamente de la reconstrucción primaria convencional. En el extremo opuesto están los casos con graves hipoplasias del acetábulo, escaso desarrollo femoral, luxación completa, discrepancia importante de las extremidades y gran cabalgamiento del trocánter mayor. Por las enormes dificultades que pueden representar para la cirugía, nos trazamos el objetivo de discutir nuestro caso, con las consideraciones y resultados del tratamiento elegido. Se presenta paciente femenina de 54 años de edad, con antecedentes de salud previa, que nos llegó a consulta con una grave deformidad congénita, acortamiento del miembro inferior derecho (6 cm) y limitación dolorosa de todos los movimientos de la cadera. Se constata una luxación congénita grado C de Hartofilakidis y IV de Crowe, que muestra como parte del tratamiento, la artroplastia total con injerto autólogo y reimplantación del cótilo en el acetábulo verdadero, para recuperar el centro de rotación del acetábulo y la osteotomía femoral de acortamiento para la implantación del vástago femoral. Se exponen los requerimientos, procederes técnicos y resultados alcanzados(AU)


Osteoarthritis secondary to congenital hip dysplasia or dislocation poses great difficulties for the surgeon reconstructing the hip. Cases with little deformity do not differ practically from conventional primary reconstruction. At the opposite end there are cases with severe acetabulum hypoplasia, poor femoral development, complete dislocation, significant limb discrepancy, and great thrust of the greater trochanter. Due to the enormous difficulties that they can represent for surgery, we set the objective of discussing our case, with the considerations and results of the chosen treatment. A 54-year-old female patient is reported, she has previous health history, and she came for consultation with severe congenital deformity, shortening of her right lower limb (6 cm) and painful limitation of all hip movements. Congenital dislocation grade C of Hartofilakidis and IV of Crowe was confirmed, which showed as part of the treatment, the total arthroplasty with autologous graft and reimplantation of the cup in the true acetabulum, to recover the center of rotation of the acetabulum and the shortening femoral osteotomy for implantation of the femoral stem. Requirements, technical procedures and results achieved are informed(AU)

ABSTRACT

Introducción: El recambio acetabular primario puede llegar a ser una intervención de gran complejidad en dependencia del defecto óseo existente. Las lesiones pueden ser segmentarias, cavitarias o combinadas. Este último patrón es el que se observa con mayor frecuencia en pérdidas óseas periprotésicas por aflojamiento aséptico. Objetivos: Mostrar la evolución de la cirugía de recambio en la artroplastia de cadera, y orientar al cirujano en la toma de decisiones de modo individualizado, para evitar las complicaciones. Método: Se realizó la investigación basada en el tema de estudio, mediante la revisión de libros de texto de la especialidad, artículos científicos publicados en diferentes bases de datos informáticas: Pubmed/MEDLINE, SciELO, BVS, Scopus, Ebsco, Google Scholar, Cochrane, así como otras consultas en bibliotecas médicas. Análisis de la información: Las prioridades en la planificación de la reconstrucción se establecen para proporcionar un implante estable, restaurar la masa ósea y optimizar la biomecánica de la cadera, aunque son los hallazgos intraoperatorios los que definitivamente indicarán el tipo de intervención a seguir. Las exigencias funcionales de los pacientes y las comorbilidades deben ser consideradas, así como el coste-efectividad de la reconstrucción planificada. Conclusiones: La artroplastia total de cadera ha demostrado mejorar significativamente la calidad de vida en pacientes, con una baja tasa de complicaciones. Para prevenir el aflojamiento aséptico es necesario ser cuidadosos en la técnica de colocación de los componentes protésicos y utilizar el tipo de material más adecuado a la edad, demanda funcional y reserva ósea de cada paciente(AU)


Introduction: Primary acetabular replacement can become a highly complex intervention depending on the existing bone defect. Lesions can be segmental, cavitary, or combined. This last pattern is the one most frequently observed in periprosthetic bone loss due to aseptic loosening. Objectives: To show the evolution of replacement surgery in hip arthroplasty, and to guide the surgeon in making individualized decisions, to avoid complications. Method: A research was carried out on the study topic, by reviewing specialty textbooks, scientific articles published in different databases such as Pubmed/ MEDLINE, SciELO, BVS, Scopus, Ebsco, Google Scholar, Cochrane, as well as other inquiries in medical libraries. Information analysis: Reconstruction planning priorities are established to provide a stable implant, restore bone mass, and optimize hip biomechanics, although it is the intraoperative findings that will definitely indicate the type of intervention to follow. The functional demands of the patients and the comorbidities must be considered, as well as the cost-effectiveness of the planned reconstruction. Conclusions: Total hip arthroplasty has been shown to significantly improve the quality of life in patients, with low rate of complications. To prevent aseptic loosening, it is necessary to be careful in the technique of placement of the prosthetic components and to use the type of material most appropriate to the age, functional demand and bone reserve of each patient(AU)

ABSTRACT

Introducción: La cirugía de la artroplastia y el recambio de una prótesis de cadera es una cirugía compleja y costosa. La estrategia quirúrgica y componentes protésicos son completamente diferentes en función de las deformidades óseas existentes y características anatómicas personales de cada paciente, por tanto, la planificación de suministros de los diferentes componentes es básica para cubrir las demandas de la población necesitada y la adecuada eficiencia económica para evitar gastos innecesarios por sobreestimación o infraestimación de las demandas. Objetivos: Determinar las necesidades por medidas de los diferentes tipos de componentes protésicos utilizados en la artroplastia total de cadera en las provincias centrales y de este modo optimizar las inversiones, con las ventajas económicas que supone. Métodos: Estudio longitudinal descriptivo retrospectivo de los casos operados de artroplastia total de cadera en el Hospital Arnaldo Milián Castro de Villa Clara, desde diciembre de 1998 hasta la fecha. Se analizan las variables edad, sexo, procedencia y componentes protésicos. Se recoge la información en la base de datos creada en SPSS, donde se realizan los análisis estadísticos. Resultados: La edad media fue 62,36 años. El grupo de 61 - 80 años fue el de mayor incidencia con 215 pacientes. Predominó el sexo masculino 51,8 por ciento. La mayor incidencia, correspondió a Villa Clara con 692 pacientes. Los componentes cementados 46 - 50 fueron los más usados y en los no cementados los más usados fueron 48-56. Vástagos Tipo Müller 7.5 - 12.5. RALCA Cementadas T0-T4, no cementados T1-T3. En las SLA, 11.5 y 13. Los cuellos estándar fueron los de mayor incidencia con 390 pacientes. Conclusiones: Con las incidencias de las diferentes medidas utilizadas por cada uno de los componentes expresados, se puede determinar con bastante exactitud la demanda de cada medida por cada 100 casos pendientes de operación. Esto permite satisfacer las demandas de las medidas más usadas y hacer una distribución apropiada a la hora del suministro, lo que redundaría en un beneficio económico vital en las actuales condiciones del país(AU)


Introduction: The arthroplasty surgery and the replacement of a hip replacement is a complex and expensive surgery. The surgical strategy and prosthetic components are completely different depending on the existing bone deformities and personal anatomical characteristics of each patient, therefore, the planning of supplies of the different components is essential to meet the demands of the needy population and adequate economic efficiency to avoid unnecessary expenses due to overestimation or underestimation of claims. Objective: To determine the needs by measurements of the different types of prosthetic components used in total hip arthroplasty in the central provinces and thus optimize investments, with the economic advantages that it entails. Methods: A retrospective descriptive longitudinal study was carried out of the total hip arthroplasty operated cases at Arnaldo Milián Castro Hospital in Villa Clara, from December 1998 to date. Age, sex, origin and prosthetic components are the variables examined. The information is collected in the database created in SPSS, statistical analyzes was performed. Results: The mean age was 62.36 years. The group of 61-80 years was the one with the highest incidence (215 patients). Male sex predominated (51.8 percent). The highest incidence corresponded to Villa Clara (692 patients). The cemented components 46-50 were the most used and in the uncemented components the most used were 48-56. Müller Stems 7.5 - 12.5. RALCA Cemented T0-T4, uncemented T1-T3. In the SLA the most used were 11.5 and 13 respectively. Standard necks were those with the highest incidence (390 patients). Conclusions: The demand for each measure can be determined quite accurately for every 100 cases pending operation with the incidents of the different measures used by each of the components expressed, allowing to meet the demands of the most used measures and appropriate distribution at supplying, which would result in vital economic benefit in the current conditions of the country(AU)

ABSTRACT

Introducción: La artroplastia total de cadera es uno de los procedimientos más exitosos del siglo veinte. Cuando se realizan de manera simultánea, presentan varios beneficios como son: menor costo, menor estadía hospitalaria, uso de una sola dosis de anestésico y retorno precoz a las actividades diarias. Objetivo: Presentar el primer caso de artroplastia total bilateral simultánea, realizado satisfactoriamente en el Hospital Universitario Manuel Ascunce Domenech en la provincia de Camagüey. Presentación del caso: Paciente femenina de 78 años de edad, color de piel blanca, con antecedentes de coxartrosis bilateral de cinco años de evolución con dolor moderado y crisis de dolor intenso a predominio de la cadera izquierda. Presentó además escoliosis antálgica. A la exploración física se constató limitación a la abducción de ambas caderas con predominio de la izquierda, con las maniobras de Patrick, Thomas y Trendelemburg positivas bilaterales. En la radiografía simple de pelvis ósea anteroposterior se observaron: disminución marcada del espacio articular, osteofitos marginales bilaterales y esclerosis subcondral marcada. Se decidió realizar una artrolplastia total bilateral en un tiempo quirúrgico, una vez evaluadas las condiciones clínicas de la paciente y su consentimiento. Se utilizó el sistema Surgival no cementado. Conclusiones: La artoplastia total de cadera se presenta como un procedimiento factible, que proporciona numerosas ventajas, y aunque no está exento de complicaciones, estas no representan un riesgo sobreañadido, siempre y cuando se seleccionen los pacientes de manera adecuada. El caso presentado, evolucionó de manera satisfactoria tras dos años de realizada la cirugía(AU)


Introduction: Total hip replacement is one of the most successful procedures of the twentieth century. When performed simultaneously, it poses several benefits such as lower cost, shorter hospital stay, use of a single dose of anesthetic and early return to daily activities. Objective: To report the first case of simultaneous bilateral total arthroplasty, successfully performed at Manuel Ascunce Domenech University Hospital in Camagüey province. Case report: This is a case of a 78-year-old female patient, white skin color, with a five-year history of bilateral coxarthrosis, moderate pain and crisis of intense pain mainly in the left hip. She also had antalgic scoliosis. The physical examination revealed abduction limitation of both hips mainly on the left, with positive bilateral Patrick, Thomas and Trendelenburg maneuvers. In the plain anteroposterior bone pelvis radiograph marked decrease in joint space, bilateral marginal osteophytes, and marked subchondral sclerosis were observed. It was decided to perform a bilateral total arthroplasty in a surgical time, once the clinical conditions of the patient and her consent had been evaluated. The uncemented Surgival system was used. Conclusions: Total hip replacement represents a feasible procedure, which provides numerous advantages, and although it is not exempt from complications, these do not signify added risks, as long as the patients are properly selected. The case reported here evolved satisfactorily after two years of surgery(AU)

ABSTRACT

Introducción: Existe una gran controversia con respecto a la existencia de un abordaje quirúrgico óptimo para artroplastia de cadera. El énfasis actual en la investigación ha sido examinar las posibles diferencias en los resultados funcionales entre el abordaje anterior y el abordaje posterior. Objetivo: Comparar las medidas de resultado informadas por los pacientes sometidos a artroplastia total de cadera, mediante abordajes anterior y posterior. Métodos: Se realiza una búsqueda sobre el tema en la base de datos PubMed entre los años 2010-2020 en inglés con los términos: comparación entre abordaje anterior y abordaje posterior de la cadera, abordaje anterior directo de la cadera, abordaje posterior de la cadera, y resultados de artroplastia de la cadera mediante abordajes anterior y posterior. Análisis y síntesis de la información: El abordaje anterior muestra una mayor mejora en la velocidad de la marcha, la longitud del paso y la simetría de la marcha, en comparación con el abordaje posterior para artroplastia de cadera al mes después de la operación. A los cuatro meses estas características de la marcha no fueron diferentes, pero los resultados de algunas pruebas funcionales fueron superiores en los pacientes intervenidos por abordaje anterior. Conclusiones: La elección del abordaje quirúrgico para artroplastia de cadera debe basarse en los factores del paciente, la preferencia del cirujano y su experiencia(AU)


Introduction: There is great controversy regarding the existence of an optimal surgical approach for hip arthroplasty. The current research emphasis has been to examine the possible differences in functional outcomes between anterior and posterior approaches. Objective: To compare the outcome measures reported by patients undergoing total hip arthroplasty, using anterior and posterior approaches. Methods: A search is carried out on the subject in the PubMed database during the years 2010-2020, in English, with the terms comparison between anterior approach and posterior approach to the hip, direct anterior approach to the hip, posterior approach to the hip, and results of hip arthroplasty using anterior and posterior approaches. Analysis and synthesis of the information: The anterior approach showed greater improvement in gait speed, stride length and gait symmetry, compared to the posterior approach for hip arthroplasty one month after the operation. At four months, these gait characteristics were not different, but the results of some functional tests were superior in patients operated on by anterior approach. Conclusions: The choice of the surgical approach for hip arthroplasty should be based on the patient´s factors, preference of the surgeons and their experience(AU)

ABSTRACT

Introducción: Las infecciones de artroplastia total de cadera tienen una incidencia baja, pero cuando suceden generan un problema sanitario no solo para el paciente, sino también para el sistema de salud. Las mismas pueden generar dolor, disminución de la capacidad funcional, pobre calidad de vida, múltiples cirugías, y en ocasiones, la muerte. Objetivos: Evaluar la incidencia nacional de infecciones en las artroplastias primarias de cadera operadas por artrosis en el 2014 en Uruguay, y los factores de riesgo vinculados al paciente, medio ambiente y acto quirúrgico, incluido el abordaje quirúrgico. Métodos: Estudio observacional analítico de todos los pacientes operados por artrosis. Se selecciona una muestra aleatoria de 633 pacientes, representativa de las 1738 artroplastias realizadas en Uruguay durante el año 2014. Mediante entrevista telefónica y revisión de historias clínicas se identificaron los pacientes con infección profunda del sitio quirúrgico. Se estimó la incidencia de infección y se realizó un análisis uni- multivariado mediante regresión logística para identificar factores asociados a la infección periprotésica profunda. Resultados: Se presentaron 8 infecciones, con una incidencia de 1,21 por ciento (IC 95 por ciento 0,59 ­ 2,20) en la población general. Los factores asociados a la infección protésica con significancia estadística fueron: a) IMC ≥ 35, p= 0,006; b) procedencia de Montevideo 2,07 por ciento (1,03 ­ 4,11) p= 0,031; c) procedencia del subsector privado 1,47 por ciento (0,77 ­ 2,78) p= 0,009; d) centro quirúrgico donde se realizó la cirugía 4,3 % (1,6 ­ 10,9) p= 0,03, e) uso de cemento con antibiótico 1,59 por ciento (0,65 ­ 3,25) p= 0,034. Se presentó sospecha de infección en 6 de 8 pacientes, en los primeros 30 días postoperatorios; a 7 de 8 pacientes se les realizó limpieza quirúrgica y solo a 1 de 8 pacientes se le realizó la revisión protésica definitiva. Conclusiones: La incidencia de infección en cirugía protésica electiva de cadera por artrosis en el Registro Nacional de Uruguay, fue similar a lo publicado en la bibliografía. De las variables frecuentemente citadas como incidentales en esta complicación, solo el índice de masa corporal fue asociado en esta serie. Llaman la atención las asociaciones dependientes de la procedencia, nivel socioeconómico y centro quirúrgico. Los resultados respecto al uso de cemento con antibiótico deben ser evaluados en estudios futuros(AU)


Introduction: Total hip arthroplasty infections have a low incidence, but when they occur they generate health problems for the patient, and for the health system. They can cause pain, decreased functional capacity, poor quality of life, multiple surgeries, and sometimes death. Objectives: To evaluate the national incidence of infections in primary hip arthroplasties operated for osteoarthritis in 2014, and the risk factors related to the patient, the environment and the surgical act, including the surgical approach. Methods: Analytical observational study of all patients operated on for osteoarthritis. A random sample of 633 patients was selected, representative of 1738 arthroplasties performed in Uruguay in 2014. Through a telephone interview and review of medical records, patients with deep infection of the surgical site were identified. The incidence of infection was estimated and univariate and multivariate analysis was performed using logistic regression to identify factors associated with deep periprosthetic infection. Results: There were 8 infections, with an incidence of 1.21 percent (95 percent CI 0.59 - 2.20) in the general population. The statistically significant factors associated with prosthetic infection were: a) BMI ≥ 35, p = 0.006; b) origin of Montevideo 2.07 percent(1.03 - 4.11) p = 0.031; c) origin of the private subsector 1.47 percent (0.77 - 2.78) p = 0.009; d) surgical center where the surgery was performed 4.3 percent(1.6 - 10.9) p = 0.03, e) use of cement with antibiotic 1.59 percent(0.65 - 3.25) p = 0.034. Suspicion of infection was presented in 6 of 8 patients, in the first 30 postoperative days; 7 of 8 patients underwent surgical cleaning and only 1 of 8 patients underwent final prosthetic revision. Conclusions: The incidence of infection in elective prosthetic hip surgery for osteoarthritis in the Uruguayan National Registry was similar to that published in the literature. Body mass index was the only variable associated as incidental to this complication in this series, out of those frequently cited. The associations depending on the origin, socioeconomic level and surgical center are striking. The results regarding the use of cement with antibiotics should be evaluated in future studies(AU)

ABSTRACT

Abstract The present study aims to demonstrate how biomodels can be used as teaching tools for surgical techniques and training in a medical residency service. A case series was carried out in our orthopedics and traumatology outpatient facility using three-dimensional (3D) printing for surgical planning to contribute to the surgical teaching and training of resident physicians. Two cases were selected as examples in the present article. Biomodels enable a better understanding of the surgery by the surgical team and residents, reducing the surgical time and the risks for the patients. These models can be a good teaching method to plan reconstructions of total hip arthroplasties, evaluate and predict surgical difficulties, and optimize procedures.


Resumo O objetivo deste trabalho é demonstrar como os biomodelos podem servir como ferramenta de ensino para o esclarecimento de técnicas cirúrgicas e o treinamento em um serviço de residência médica. Foram realizadas séries de casos em nosso ambulatório de ortopedia e traumatologia, nos quais o uso da prototipagem para o planejamento cirúrgico contribuiu para o ensino cirúrgico e treinamento de médicos residentes. Dois casos foram selecionados como exemplo neste artigo. O uso de biomodelos permite um melhor entendimento da cirurgia pela equipe cirúrgica e pelos residentes, e diminui o tempo e os riscos cirúrgicos aos pacientes. O uso de biomodelos no planejamento de reconstruções da artroplastia total do quadril pode servir como um bom método de ensino, para a avaliação e previsão das dificuldades no momento da cirurgia, e para otimizar os procedimentos.

ABSTRACT

Abstract Objective The objective of the present work was to compare the measurement of acetabular component version on anteroposterior (AP) and on cross-table radiographs after total hip arthroplasty (THA). Methods Radiographs of 60 hips with a primary THA were selected. Version was calculated on the AP radiograph using the Lewinnek method and, on the cross-table, using the Woo and Morrey direct method. Results Mean and standard deviation (SD) were different on both radiographs, being 9.7° ± 5.5° on the AP, whereas in the cross-table the measurements were 20.6° ± 8.4° (p < 0.001). Minding our aim of 10°, the cross-table measurements were statistically different from it (p < 0.001), while the AP measurement did not differ (p = 0.716). Conclusion The present study showed that the best way to correctly evaluate the acetabular component positioning following a THA is by measuring anteversion and abduction on an AP radiograph after confirming, in a cross-table radiograph, that the component is not retroverted.


Resumo Objetivo O objetivo do presente trabalho foi comparar a medição da versão do componente acetabular em radiografias em incidência anteroposterior (AP) e crosstable após artroplastia total do quadril (ATQ). Métodos Foram selecionadas radiografias de 60 quadris com ATQ primário. A versão foi calculada na radiografia AP usando o método de Lewinnek e, na cross-table, usando o método direto do Woo e Morrey. Resultados A média e o desvio padrão (DP) foram diferentes em ambas as radiografias, sendo 9,7° ± 5,5° no AP, enquanto na cross-table foram 20,6° ± 8,4° (p < 0,001). Considerando nosso objetivo de 10°, as medidas da cross-table foram estatisticamente diferentes dele (p < 0,001), enquanto a medição AP não diferiu (p = 0,716). Conclusão O presente estudo mostrou que a melhor maneira de avaliar corretamente o posicionamento do componente acetabular após uma ATQ é medindo a anteversão e a abdução em uma radiografia AP após confirmar, em uma radiografia cross-table, que o componente não é retrovertido.

ABSTRACT

The outcome of total hip arthroplasty (THA) in dogs is directly related to surgical planning. Templating of radiographs prior to THA should help the surgeon anticipate prosthesis size and femoral shape allowing canal fill of the proximal metaphysis by the implant ensuring primary stable fixation. The canal flare index (CFI) obtained from radiograph has been used as a measure of risk of complications for the technique in human beings and dogs. However, standard radiographs only provide limited data for the selection of cementless prostheses and the assessment of their fit within the femoral canal, due to factors like radiographic magnification and femoral rotation. Therefore, three-dimensional evaluation based on computed tomography (CT) may be a better tool for CFI measurement. The aim of this study was to compare anatomical measurement with CFI values obtained from craniocaudal radiography and CT. Craniocaudal radiographs using a horizontal radiographic beam (CR), CT, and anatomical macroscopic measurements (A) were obtained from 45 femurs from 23 canine cadavers. The differences between the values of CFI obtained from radiograph (CFI-R), computed tomography on transverse (CFI- TT) and longitudinal axis (CFI-TL) compared to the CFI obtained from macroscopic measurements - gold standard - (CFI-A), and 95% limits of agreement (LOA) between the values, were evaluated by the Bland-Altman method. Dimensions obtained from CT techniques had a greatest mean difference from anatomical and CFI values were also different (P=0.032). Under the experimental conditions, the craniocaudal radiograph, provided the most accurate measurement of the CFI (mean difference: 0.087 ± 0.42).(AU)


O resultado da artroplastia total do quadril (ATQ) em cães está diretamente relacionado ao planejamento cirúrgico. O templating radiográfico pré-operatório da ATQ deve ajudar o cirurgião a prever o tamanho da prótese e o formato do fêmur, o que permitirá um preenchimento ideal da metáfise proximal pelo implante, garantindo, assim, fixação primária estável. O índice de alargamento do canal (Canal Flare Index - CFI) obtido em radiografias tem sido utilizado como fator de risco de complicações para a técnica em humanos e cães. No entanto, as radiografias podem fornecer apenas dados limitados para a seleção de próteses não cimentadas e a avaliação do seu encaixe no canal femoral, devido a fatores como ampliação radiográfica e rotação femoral. Portanto, a avaliação tridimensional baseada na tomografia computadorizada (TC) pode ser uma ferramenta vantajosa para a mensuração do CFI. O objetivo deste estudo foi comparar a medida anatômica com os valores de CFI obtidos na radiografia craniocaudal e na TC. Radiografias craniocaudais utilizando feixe radiográfico horizontal (CR), tomografia computadorizada e medidas macroscópicas anatômicas (A) foram obtidas de 45 fêmures de 23 cadáveres caninos. As diferenças entre os valores de CFI obtidos na radiografia (CFI-R), na tomografia computadorizada no eixo transversal (CFI-TT) e no eixo longitudinal (CFI-TL), em comparação com os valores de CFI obtidos nas medições macroscópicas - padrão-ouro - (CFI-A) e os limites de concordância de 95% (LOA) entre os valores, foram avaliadas pelo método de Bland-Altman. As dimensões obtidas pelas técnicas de TC apresentaram maior diferença média dos valores anatômicos, e as do CFI também foram diferentes (P=0,032). Nas condições experimentais, a radiografia craniocaudal forneceu a medida mais precisa do CFI (diferença média: 0,087 ± 0,42) para representar o padrão-ouro deste estudo.(AU)

ABSTRACT

OBJECTIVE@#To compare the clinical efficacy of total hip arthroplasty with conventional instrument OCM approach and posterolateral approach in supine position.@*METHODS@#From February 2017 to January 2019, 67 patients underwent hip arthroplasty due to hip diseases, including 21 patients in the minimally invasive group, 12 males and 9 females;there were 10 cases of femoral neck fracture, 5 cases of aseptic necrosis of femoral head and 6 cases of hip osteoarthritis. In the traditional group, 46 cases were treated by traditional posterolateral approach, including 28 males and 18 females;there were 24 cases of femoral neck fracture, 12 cases of aseptic necrosis of femoral head and 10 cases of hip osteoarthritis. All patientsused biological ceramic artificial joint prosthesis. The operation time, intraoperative bleeding, incision length, preoperative and postoperative creatine kinase (CK-NAC), underground activity time, hospital stay, abduction angle and anteversion angle of prosthesis were observed and compared between two groups. Harris scores before operation and 12 months after operation were compared between two groups.@*RESULTS@#All cases were followed up for 14 to 26(18.4±3.6) months. There was no significant difference in intraoperative bleeding, postoperative anteversion and abduction angle between two groups (@*CONCLUSION@#The two approaches of total hip arthroplasty can obtain satisfactory results.OCM approach has less damage and rapid postoperative recovery. It is a reliable surgical approach and can be popularized and used.

ABSTRACT

The rotation center of traditional hip disarticulation prosthesis is often placed in the front and lower part of the socket, which is asymmetric with the rotation center of the healthy hip joint, resulting in poor symmetry between the prosthesis movement and the healthy lower limb movement. Besides, most of the prosthesis are passive joints, which need to rely on the amputee's compensatory hip lifting movement to realize the prosthesis movement, and the same walking movement needs to consume 2-3 times of energy compared with normal people. This paper presents a dynamic hip disarticulation prosthesis (HDPs) based on remote center of mechanism (RCM). Using the double parallelogram design method, taking the minimum size of the mechanism as the objective, the genetic algorithm was used to optimize the size, and the rotation center of the prosthesis was symmetrical with the rotation center of the healthy lower limb. By analyzing the relationship between the torque and angle of hip joint in the process of human walking, the control system mirrored the motion parameters of the lower on the healthy side, and used the parallel drive system to provide assistance for the prosthesis. Based on the established virtual prototype simulation platform of solid works and Adams, the motion simulation of hip disarticulation prosthesis was carried out and the change curve was obtained. Through quantitative comparison with healthy lower limb and traditional prosthesis, the scientificity of the design scheme was analyzed. The results show that the design can achieve the desired effect, and the design scheme is feasible.

ABSTRACT

BACKGROUND@#Perioperative neurocognitive disorders (PND) are a series of severe complications in the perioperative and anesthetic periods with a decline in memory, execution ability, and information processing speed as the primary clinical manifestation. This study aimed to evaluate the impact of edaravone (EDA) on PND and peripheral blood C-X-C motif chemokine ligand 13 (CXCL13) levels in elderly patients with hip replacement.@*METHODS@#A total of 160 elderly patients undergoing hip arthroplasty in Affiliated Dongguan People's Hospital of Southern Medical University (from March 2016 to March 2018) were randomly and double-blindly categorized into an EDA group and a control group (CON). Group EDA was administered intravenously EDA 30 min before surgery, and group CON was administered intravenously saline. The cognitive function of the two groups was evaluated 1-day before the operation and at 1 and 12 months after surgery, and the incidence of post-operative delirium was tested on days 1, 3, and 7 after surgery using the Chinese version of the confusion assessment method. Serum CXCL13 and interleukin (IL)-6 concentrations were measured before anesthesia, during surgery (30 min after skin incision), and on days 1, 3, and 7 after surgery. The continuous variables in accordance with normal distribution were tested using the Student's t test, the continuous variables without normal distribution using the Mann-Whitney U test, and categorical variables by the χ2 test or Fisher exact test.@*RESULTS@#The incidence of post-operative delirium within 7 days after surgery was significantly higher in group CON than that in group EDA (31.3% vs. 15.0%, t = -5.6, P < 0.001). The modified telephone interview for cognitive status and activities of daily life scores were significantly higher in the group EDA than those in the group CON at 1 month (39.63 ± 4.35 vs. 33.63 ± 5.81, t = -2.13, P < 0.05 and 74.3 ± 12.6 vs. 61.2 ± 13.1, t = -1.69, P < 0.05) and 12 months (40.13 ± 5.93 vs. 34.13 ± 5.36, t = -3.37, P < 0.05 and 79.6 ± 11.7 vs. 65.6 ± 16.6, t = -2.08, P < 0.05) after surgery; and the incidence of neurocognitive dysfunction was significantly lower in the group EDA than that in the group CON (P < 0.05). Serum CXCL13 and IL-6 concentrations were significantly lower in the group EDA than those in the group CON during and after surgery (P < 0.05).@*CONCLUSION@#EDA can significantly reduce the serum concentrations of CXCL13 and IL-6 and improve the PND of patients.

ABSTRACT

@#OBJECTIVE: Hip and knee joint replacement procedures are an effective therapeutic intervention in treating severe joint disorders. Its use has been increasingly performed worldwide, including the Philippines, with its techniques constantly evolving and the science behind it improving. This study aims to describe the demographics, clinical profiles, and outcomes of arthroplasty patients by the Arthroplasty Service, Department of Orthopedics, University of the Philippines – Philippine General Hospital (UP-PGH). METHODS: The study is a descriptive and retrospective review of patients who underwent joint replacement procedures, both primary and revision arthroplasty, from January 2012 to December 2018. Patient demographics and clinical data of patients who underwent total joint arthroplasty at the UP-PGH were collected and evaluated. RESULTS: Data from 279 patients with 306 primary joint replacement procedures were analyzed. There were 195 total hip arthroplasty procedures (THAs) and 111 total knee arthroplasty procedures (TKAs) done. The mean age for THA patients was 55.6 years old, with more females (68.2%) with the left hip being more commonly affected (54.9%). The most common indication for THA was an untreated femoral neck fracture (23.1%) followed by avascular necrosis (20.5%). Cementless fixation was the most commonly used technique (61.5%). Meanwhile, the mean age for TKA was 64.5 years old, with the majority having degenerative osteoarthritis, and using cemented TKA fixation for all knees. A total of 37 revision arthroplasty cases were performed, with 34 in the hip and three in the knee, with infection being the most common overall indication (53%). CONCLUSION: The demographics, clinical profiles, and outcomes of the UP-PGH Arthroplasty Service are comparable to other centers internationally, and further emphasizes the satisfactory outcomes of these procedures. Meanwhile, suggested explanations for the subtle differences are discussed in this study.

ABSTRACT

OBJECTIVE@#To analyze and compare the clinical efficacy of different types of surgical treatment of periprosthetic femoral fracture(PFF) after hip arthroplasty (HA).@*METHODS@#From September 2010 to September 2016, 47 patients (47 hips) with periprosthetic fractures after total hip arthroplasty were retrospectively analyzed, including 13 males and 34 females. According to Vancouver classification, there were 2 patients with type AG, 17 patients with type B1, 19 patients with type B2, 7 patients with type B3 and 2 patients with type C. The age of patients ranged from 56 to 94 (71.5±8.3) years. After admission, nutritional risk screening (NRS2002) was used to assess the nutritionalstatus of the patients. Eighteen patients (38%) had malnutrition risk (NRS>3 points). After admission, the patients were given corresponding surgical treatment according to different types. Intraoperative blood loss was recorded. Harris score was used to evaluate the hip function. VAS pain score was performed on admission and after operation.@*RESULTS@#All the 47 patients were followed up for 19 to 62 (34±11) months. The Harris scores were (41.8±12.1) and (89.0±2.6) respectively before and 1 year after operation, and the difference was statistically significant (@*CONCLUSION@#The treatment of hip periprosthetic fracture patients should be based on the general situation of patients, imaging data, intraoperative correction classification, etc. to develop individualized treatment plan in line with patients. For patients with preoperative malnutrition risk, preoperative nutritional intervention may reduce intraoperative bleeding.

ABSTRACT

BACKGROUND@#Aspirin has demonstrated safety and efficacy for venous thromboembolism (VTE) prophylaxis following total hip arthroplasty (THA); however, inconsistent dose regimens have been reported in the literature. This study aimed to evaluate and compare the safety and efficacy of 100 mg aspirin twice daily with rivaroxaban in VTE prophylaxis following THA.@*METHODS@#Patients undergoing elective unilateral primary THA between January 2019 and January 2020 were prospectively enrolled in the study and randomly allocated to receive 5 weeks of VTE prophylaxis with either oral enteric-coated aspirin (100 mg twice daily) or rivaroxaban (10 mg once daily). Medication safety and efficacy were comprehensively evaluated through symptomatic VTE incidence, deep vein thrombosis (DVT) on Doppler ultrasonography, total blood loss (TBL), laboratory bloodwork, Harris hip score (HHS), post-operative recovery, and the incidence of other complications.@*RESULTS@#We included 70 patients in this study; 34 and 36 were allocated to receive aspirin and rivaroxaban prophylaxis, respectively. No cases of symptomatic VTE occurred in this study. The DVT rate on Doppler ultrasonography in the aspirin group was not significantly different from that in the rivaroxaban group (8.8% vs. 8.3%, χ2 = 0.01, P = 0.91), confirming the non-inferiority of aspirin for DVT prophylaxis (χ2 = 2.29, P = 0.01). The calculated TBL in the aspirin group (944.9 mL [658.5-1137.8 mL]) was similar to that in the rivaroxaban group (978.3 mL [747.4-1740.6mL]) (χ2 = 1.55, P = 0.12). However, there were no significant inter-group differences in HHS at post-operative day (POD) 30 (Aspirin: 81.0 [78.8-83.0], Rivaroxaban: 81.0 [79.3-83.0], χ2 = 0.43, P = 0.67) and POD 90 (Aspirin: 90.0 [89.0-92.0], Rivaroxaban: 91.5 [88.3-92.8], χ2 = 0.77, P = 0.44), the incidence of bleeding events (2.9% vs. 8.3%, χ2 = 0.96, P = 0.33), or gastrointestinal complications (2.9% vs. 5.6%, χ2 = 1.13, P = 0.29).@*CONCLUSION@#In terms of safety and efficacy, the prophylactic use of 100 mg aspirin twice daily was not statistically different from that of rivaroxaban in preventing VTE and reducing the risk of blood loss following elective primary THA. This supports the use of aspirin chemoprophylaxis following THA as a less expensive and more widely available option for future THAs.@*TRIAL REGISTRATION@#Chictr.org, ChiCTR18000202894; http://www.chictr.org.cn/showproj.aspx?proj=33284.

ABSTRACT

OBJECTIVE@#To investigate the effect of different proximal femoral shapes on leg length discrepancy(LLD) after total hip arthroplasty(THA).@*METHODS@#Total 131 patients with osteoarthritis or osteonecrosis received unilateral biological total hip arthroplasty from June 2013 to June 2019. All patients' age, sex, side and pelvis anteroposterior digital radiography were retraspectively analyzed. There were 69 males and 62 females, 57 cases of left hip and 74 cases of right hip. The age ranges from 25 to 89 with an average age of 62 years. There were 48 cases of osteoarthritis and 83 cases of osteonecrosis. In this study, femoral cortical index (FCI) was used as the classification of proximal femoral shape, and bilateral lower limb length differences were measured by preoperative and postoperative pelvis anteroposterior digital radiography. Grouping according to FCI:> 0.6 was Dorr A group, 0.5 to 0.6 was Dorr B group, 0.6, the postoperative LLD was 6.30 mm (IQR 1.00 to 10.95 mm). When FCI was 0.5 to 0.6, the postoperative LLD was 5.85 mm(IQR-0.55 to 8.90 mm). FCI<0.5, the postoperative LLD was 1.95 mm(IQR -2.50 to 6.68 mm). LLD comparison of different proximal femoral shape was statistically significant (@*CONCLUSION@#High FCI increases the risk of lower extremity prolongation after surgery on the affectedside, while low FCI reduces the risk of lower extremity prolongation after surgery on the affected side. The surgeon can assess the shape of the proximal femur of the patient preoperatively and inform the patient in advance of possible changes in leg length of both lower extremities after total hip replacement.
