A rare case of avascular necrosis of the hip joint secondary to ochronosis

This is a case report of a 53-year-old female patient who presented with long-standing hip pain secondary to avascular necrosis of the hip joint. She underwent total hip replacement and her intraoperative findings raised suspicion of ochronosis and was retrospectively evaluated for alkaptonuria both clinically and through biochemical investigations to confirm the diagnosis

A Comparative Analysis Between Spinal and General Anesthesia for Orthopedic Surgery

Background: Many surgeries can be performed with spinal anesthesia (SA) or general anesthesia (GA). However, there are only limited and confounding data available regarding costs and anesthesia-related times. Hip or knee replacement are common orthopedic surgeries that can be performed using SA or GA without differences regarding mortality or morbidity. Observational studies have suggested that spinal anesthesia may be associated with lower risks of death, delirium and major medical complications and with shorter lengths of stay in the hospital than general anesthesia. The aim of this study was to assess and compare the effects of spinal versus general anesthesia on postoperative outcomes in patients undergoing orthopedic surgery. Material & Methods: This was a comparative observational study and was conducted in the Department of Anesthesiology of Holy Family red crescent Medical College Hospital, Dhaka, Bangladesh during the period from March,2021 to March,2023. In this study we included 200 patients undergoing orthopedic surgery. The patients were randomly divided into two groups – Group A (Patients who were given general anesthesia) & Group B (Patients who were given spinal anesthesia). Results: In total 200 patients from both the groups completed the study. In our study we found majority (44.5%) of our patients were aged 60-69 years and most of our patients were female (56%) compared to male (44%).The mean age of our patients was 61.73 ± 7.92 years. The mean BMI was 31.67±3.24 kg/m.2Among all patients ,48% had mild systemic disease and followed by 31.5% had severe systemic disease. Majority (43.5%) of our patients had hypertension, 31% had diabetes. Vomiting was found 47% in group A on contrary only 23% had vomiting in spinal group. We found the mean anesthesia induction time was significantly higher in spinal group. Anesthesia time was lower in spinal group while PACU time was higher in group B. Time duration of surgery was significantly lower in spinal group. After 24 hours, spinal group showed less pain score than general anesthesia group. Conclusion: In our study, we found that SA is associated with less fixed and variable costs and lower postoperative pain scores during the stay in the PACU. Therefore, SA is a more reasonable alternative to GA in the immediate postoperative period for patients undergoing hip or knee replacement. When compared to general anaesthesia, spinal anaesthesia provides better operating circumstances, better postoperative pain control, and faster postoperative recovery.

The cemented double mobility cup in hip revision: different possibilities of use / Acetábulo cimentado de dupla mobilidade em revisão de quadril: distintas possibilidades de uso

ABSTRACT Introduction: The aim of our work is to review those patients who underwent prosthetic hip revision surgery in our hospital considered to be patients at high risk of dislocation or recurrent dislocation, and who underwent a double mobility cemented cup (CMD). Analyzing the different ways to place these cups and the clinical results and reluxations. Material and methods: The 69 cases comprised 34 men and 35 women with a mean age of 77,39 years. The mean follow-up was 4.7536 years. The type of intervention performed varied according to the cause of the intervention, the acetabular bone stock and the state of the primary cup. In the cases in which there was a good fixation of the primary metalback, we opted to carry out a cementation of the cemented DMC into the existing well-fixed metal acetabular shell, this occurred in 23 cases. In the cases where there was loosening of the primary cup but there was a good bone stock, a CMD was cemented into the bone (21 cases). In the cases where there was a Paprosky type III we cemented a DMC to a Bursch-Schneider reinforcement ring together with the placement of a cancellous bone graft (25 cases). Results: The clinical evaluation at the end of the follow-up, according to the MD Scale, showed the mean value was 16.454 (SD 0.79472), with a survival at the end of the follow-up of 100% of the placed DMC. Conclusion: The use of cemented DMC is a good solution in the replacement of THA, especially in cases of reluxation or risk of dislocation due to personal or technical predisposing factors. The use of these DMC cemented can be directly to the bone, into the existing well-fixed metal Shell, or cemented to a reinforcing ring, depending on the acetabular defect. Evidence Level III; Comparative Case Series.

RESUMO Introdução: Revisar os pacientes que foram submetidos à cirurgia de revisão protética de quadril neste hospital, considerados como pacientes com alto risco de luxação ou luxação recorrente, submetidos a cirurgia por acetábulo cimentado de dupla mobilidade (CMD). Analisando as diferentes formas de posicionamento desses copos, seus resultados clínicos e reluxações. Material e métodos: Os 69 casos correspondiam a 34 homens e 35 mulheres com uma idade média de 77,39 anos. O tempo médio de acompanhamento foi de 4,7536 anos. O tipo de intervenção realizada variou de acordo com a causa da intervenção, o estoque ósseo acetabular e o estado do copo primário. Nos casos em que houve uma boa fixação do metal primário, optouse por realizar uma cimentação do DMC cimentado na cúpula acetabular metálica firme existente, o que ocorreu em 23 casos. Nos casos em que houve um afrouxamento acetabular primário com um bom estoque ósseo disponível, cimentou-se um CMD (21 caixas). Nos casos em que havia um Paprosky tipo III, cimentou-se um DMC a um anel de reforço Bursch-Schneider juntamente com a colocação de um enxerto ósseo esponjoso (25 caixas). Resultados: A avaliação clínica realizada no final do acompanhamento, de acordo com a Escala MD, mostrou que o valor médio foi de 16,454 (DP 0,79472), com uma sobrevivência ao final do acompanhamento de 100% do DMC inserido. Conclusão: O uso do DMC cimentado pode ser uma boa solução para substituição do THA, especialmente em casos de reluxação ou risco de deslo-camento devido a fatores de predisposição pessoais ou técnicos. O uso destes DMC cimentados pode ser realizado diretamente ao osso, dentro da cúpula metálica fixa existente, ou cimentados a um anel de reforço, dependendo do defeito acetabular.

Prevalencia de portación nasal de Staphylococcus aureus sensible y resistente a la meticilina en candidatos a artroplastia total de cadera o rodilla / Prevalence of nasal carriage of methicillin-sensitive and methicillin-resistant Staphylococcus aureus in candidates for total hip or knee arthroplasty

INTRODUCIÓN Las infecciones perioperatorias en cirugía de reemplazo articular son fuente importante de morbimortalidad, así como de altos costos económicos y sociales, tanto para el paciente como para su entorno. La colonización preoperatoria por Staphylococcus aureus ha sido reconocida como un factor de riesgo importante para desarrollar una infección de sitio quirúrgico.El objetivo de este estudio es conocer la prevalencia de portación nasal de S. aureus, tanto sensible a la meticilina (SASM) como resistente a la meticilina (SARM), en pacientes candidatos a cirugía de reemplazo articular de cadera o rodilla. MATERIALES Y MÉTODOS Se realizó un estudio observacional de una cohorte retrospectiva de pacientes con indicación de artroplastia total de cadera (ATC) y rodilla (ATR) electiva por artrosis severa en un hospital público de Chile. Los pacientes fueron sometidos a tamizaje preoperatorio de portación, cultivándose muestras obtenidas mediante hisopado de ambas fosas nasales. Los datos del laboratorio fueron recopilados y presentados como porcentaje de portación de S. aureus. RESULTADOS Se estudiaron 303 pacientes consecutivos de ATC y 343 de ATR. En total, 483 de los 646 pacientes (74,7%) tuvieron estudio preoperatorio de portación nasal. Se identificaron 123 pacientes (25,4%) portadores de S. aureus, de los cuales sólo 2 (0,41%) casos correspondieron a SARM. CONCLUSIÓN La prevalencia de portación nasal de S. aureus obtenida fue de 25%, similar a lo reportado en otras series. La prevalencia de SARM (0.41%), sin embargo, estuvo bajo lo descrito en la literatura internacional (0,6­6%). Sería de utilidad, dada la alta prevalencia de portación descrita en nuestro trabajo y de acuerdo a evidencia publicada recientemente, realizar protocolos de descolonización universales, sin necesidad de realizar tamizaje preoperatorio.

INTRODUCTION Surgical-site infections in joint replacement surgery are an important source of morbidity and mortality that entail high economic and social burden both for the patient and their environment. Preoperative colonization by Staphylococcus aureus has been recognized as an important risk factor for the development of surgical-site infection. The aim of the present study is to determine the prevalence of nasal colonization by S. aureus, both methicillin-sensitive (MSSA) and methicillin-resistant (MRSA) in patients who are candidates for total replacement of the hip or knee joints. MATERIALS AND METHODS A retrospective observational study of a cohort of 646 patients with an indication to undergo total hip arthroplasty (THA) or total knee arthroplasty (TKA) due to severe osteoarthritis was performed in a Public Hospital in Chile. The patients were submitted to a preoperative screening for S. aureus carriage, and the culture samples were obtained by swabbing both nostrils. The laboratory data was collected and presented as a percentage of carriage. RESULTS We consecutively examined 303 THA and 343 TKA patients. A total of 483 of the 646 patients (74.7%) underwent a preoperative study of nasal carriage. We identified 123 (25.4%) S. aureus carriers, and only found 2 (0.41%) cases corresponding to MRSA. CONCLUSION We found a prevalence of nasal carriage of S. aureus of 25.4%, a rate similar to that reported in other series. The prevalence of MRSA (0.41%), however, was lower than that reported in the international literature (0.6­6%). Given the high prevalence of carriage described in our work and according to recently published data, it would be worthwhile to carry out universal decolonization protocols, without the need for preoperative screening.

The cost of total hip replacement: a multicentric TDABC comparison in Brazil / O custo da artroplastia de quadril: uma comparação multicêntrica TDABC no Brasil

Objective: Monitoring costs is critical in searching for a more effective healthcare system. This study aimed to comprehend the care pathway and measure the costs associated with hip replacement surgeries in different hospitals in Brazil. Methods: The time-driven activity-based costing method was applied for cost data collection and analyses. Data on 62 patients were retrieved from five public hospitals. A descriptive cost analysis was followed by a comprehensive analysis of the variability in each hospital's care process, leading to suggestions for cost-saving opportunities along with the surgical care pathway. As a final analysis, the cost of surgical treatment was contrasted with the national reimbursement fee. Results: The mean cost per patient of the total sample was $5,784 (MIN-MAX $2,525.9-$9,557.8). Pre- and post-surgery hospitalization periods demonstrated the highest variability in length of time and resource consumption among centers. Compared to the national best practice fee, the average cost per inpatient total hip arthroplasty (THA) pathway from all six hospitals was approximately 7x the national reimbursement. Conclusion: The application of the TDABC allowed us to identify differences in the surgical care pathway among hospitals, which could be explored in further studies aimed at designing a benchmark surgical pathway. Differences in how the treatment is delivered to patients also justified the high-cost variability among centers.

Objetivo: O custo do monitoramento é um elemento-chave na busca contínua por um sistema de saúde mais eficaz. O objetivo deste estudo foi compreender a trajetória assistencial e mensurar os custos associados às cirurgias de artroplastia do quadril em diferentes hospitais do Brasil. Métodos: O método de custeio baseado em atividades orientado pelo tempo foi aplicado para a coleta e análise de dados de custos. Os dados de 62 pacientes foram recuperados de cinco hospitais públicos. Uma análise descritiva de custos foi seguida por uma análise abrangente da variabilidade no processo de atendimento de cada hospital, levando a sugestões de oportunidades de redução de custos junto com a via de atendimento cirúrgico. Como análise final, o custo do tratamento cirúrgico foi contrastado com o valor de reembolso nacional. Resultados: O custo médio por paciente da amostra total foi de $ 5.784 (MIN-MAX $ 2.525,9-$ 9.557,8). Os períodos de internação pré e pós-operatórios demonstraram a maior variabilidade no tempo e no consumo de recursos entre os centros. Em comparação com o reembolso nacional de melhores práticas, o custo médio por cirurgia de prótese de quadril de paciente internado de todos os seis hospitais foi de aproximadamente 7x o reembolso nacional. Conclusão: A aplicação do TDABC nos permitiu identificar diferenças na via de atendimento cirúrgico entre hospitais, o que poderia ser explorado em estudos futuros que visem projetar uma via cirúrgica de referência. As diferenças na forma como o tratamento está sendo entregue aos pacientes também contribuíram para justificar a alta variabilidade dos custos entre os centros.

Among them, the clinical compliance rate of 5 review indicators were greater than 80%, and the clinical compliance rate of 12 review indicators were less than 80%. The main obstacles were due to the imperfect venous thromboembolism (VTE) risk assessment and management process at the system level, and the low level of knowledge of VTE prevention and management among medical staff at the individual level.Conclusions:This study was based on the best evidences, scientifically and systematically developed clinical review indicators, rigorously and comprehensively analyzed obstacles, and constructed targeted improvement measures, not only for the future physical prevention of perioperative venous thrombosis in patients with total knee and hip replacement surgery transformation provides the basis but also can further promote clinical practice changes and continuous quality improvement.

Effects of Gait Level on Bone Remodeling around Hip Prosthesis after Hip Replacement / 医用生物力学

Objective To investigate changes in gait level of patients after hip replacement, the variation trend of bone mineral density (BMD) around the prothesis was studied, so as to reveal the influence pattern of gait level at postoperative initial and long-term stages on bone reomodeling. Methods Based on adaptive bone remodeling theory, the finite element model of femer-prosthesis was developed. The BMD distribution was calculated using the initial and long-term gait level after hip replacement as the remodeling parameters. Gruen method was applied to quantify the BMD changes. Results At the postoperative initial stage, obvious variations existed in constant gait group and changing gait group. The maximum difference occurred in low gait group, resulting in the decrease of BMD by 41% in greater trochanter region. The improvement of gait level would promote the enhancement of BMD in proximal and middle region of the prosthesis, resulting in the increase of BMD by 47%. Long-term gait recovery would promote BMD recovery in middle and end region of prosthesis, with BMD increase by 2%-9%. Conclusions The research findings provide guidance for rehabilitation process of patients after hip replacement.

OBJECTIVE@#To explore the incidence and risk factors of readmission of elderly patients with hip fracture after hip hemiarthroplasty.@*METHODS@#A retrospective analysis of 237 elderly hip fracture patients who underwent hip hemiarthroplasty from February 2015 to October 2020 were performed. According to the readmission status of the patients at 3 months postoperatively, the patients were divided into readmission group (39 cases)and non-readmission group(198 cases). In readmission group, there were 7 males and 32 females with an average age of(84.59±4.34) years old, respectively, there were 34 males and 164 females with average age of (84.65±4.17) years old in non-readmission group. The general information, surgical status, hip Harris score and complications of patients in two groups were included in univariate analysis, and multivariate Logistic regression was used to analyze independent risk factors of patients' readmission.@*RESULTS@#The proportion of complications(cerebral infarction and coronary heart disease) in readmission group was significantly higher than that of non-readmission group (P<0.05), and intraoperative blood loss in readmission group was significantly higher than that of non-readmission group(P<0.05). Harris score of hip joint was significantly lower than that of non-readmission group(P<0.05). The proportion of infection, delirium, joint dislocation, anemia and venous thrombosis in readmission group were significantly higher than that of non-readmission group (all P<0.05). Multivariate Logistic regression analysis showed that the risk factors for readmission of elderly patients with hip fracture after hip hemiarthroplasty included cerebral infarction, infection, delirium, dislocation, anemia and venous thrombosis (all P<0.05).@*CONCLUSION@#The complications of the elderly patients who were readmission after hip hemiarthroplasty for hip fractures were significantly higher than those who were non-readmission. Cerebral infarction, infection, delirium, dislocation, anemia and venous thrombosis are risk factors that lead to patient readmission. Corresponding intervention measures can be taken clinically based on these risk factors to reduce the incidence of patient readmissions.

Conclusions: we believe that the treatment of lateral hip fractures using this technique can be an alternative for the management of patients with unstable fractures, with a high probability of osteosynthesis failure and mainly when the patient and relatives agree with the procedure.

Artroplastia de quadril no Sistema Único de Saúde: análise dos óbitos hospitalares no Estado do Rio de Janeiro, Brasil / Hip arthroplasty in the Brazilian Unified National Health System: analysis of hospital deaths in the State of Rio de Janeiro, Brazil / Artroplastia de cadera en el Sistema Único de Salud: análisis de las muertes hospitalarias en el Estado de Río de Janeiro, Brasil

O envelhecimento populacional traz desafios ao sistema de saúde. O aumento das doenças degenerativas articulares e a ocorrência de quedas podem demandar a realização de artroplastia de quadril. Objetivou-se avaliar os fatores associados a óbitos hospitalares por artroplastia de quadril no Sistema Único de Saúde (SUS), no Estado do Rio de Janeiro, Brasil. Realizou-se um estudo transversal utilizando o Sistema de Informações Hospitalares do SUS, considerando internações e óbitos por artroplastias de quadril ocorridos entre 2016-2018. As análises consideraram as internações por caráter de atendimento (eletivo, urgência e acidentes ou lesão e envenenamento). Realizou-se regressão logística binária para obter a razão de chance de óbito. A mortalidade aumentou conforme a gravidade da internação. A maioria das internações com óbito foi por fratura de fêmur, demandando cuidados intensivos, tempo médio de permanência de 21,5 dias, envolveu mulheres com 80 anos e mais, da raça/cor branca, que realizaram procedimento em unidades habilitadas em alta complexidade em ortopedia e traumatologia, municipais e classificadas como geral II, localizadas na região de moradia do usuário. A chance de óbito se mostrou significativa para a idade do usuário, uso de unidade de terapia intensiva (UTI) e permanência hospitalar. Espera-se aumento da demanda por artroplastias de quadril e reabilitação física com o envelhecimento populacional. As equipes de saúde devem estar preparadas para lidar com uma população envelhecida. Conhecer os fatores que incrementem o risco de óbito favorece o planejamento e o manejo do cuidado pela equipe hospitalar, inclusive no sentido de diminuir a permanência hospitalar, tão impactante na condição funcional de pessoas idosas.

Population aging brings challenges to the health system. Increased degenerative joint diseases and occurrence of falls may require hip arthroplasties. The objective of this study was to evaluate factors associated with hospital deaths due to hip arthroplasties in the Brazilian Unified National Health System (SUS), in the State of Rio de Janeiro, Brazil. A cross-sectional study was carried out using the Brazilian Hospital Information System of the SUS, considering hospitalizations and deaths from hip arthroplasties that occurred between 2016 to 2018. The analyses considered hospitalizations by type of care (elective, urgency and accidents or injury and poisoning). Binary logistic regression was performed to obtain a ratio for the chance of death. Mortality increased according to the severity of hospitalization. Most of the hospitalizations with death were due to femoral fracture, demanded intensive care, had mean length of stay of 21.5 days, and involved women aged 80 years and over, of the white race/color, who had their procedure performed in municipal units qualified in orthopedics and traumatology of high complexity and classified as general II, located in the patients' region of residence. The chance of death was significant for the age of the patient, use of intensive care unit (ICU), and length of hospital stay. We expect an increase in the demand for hip arthroplasties and physical rehabilitation due to population aging. Health teams must be prepared to deal with an ageing population. Knowing the factors that increase the risk of death favors care planning and management by hospital staff, including in the reduction of hospital stay, which is so impactful on the functional condition of the elderly.

El envejecimiento poblacional trae desafíos al sistema de salud. El aumento de las enfermedades degenerativas articulares y la incidencia de caídas pueden demandar la realización de artroplastias de cadera. Tuvo como objetivo evaluar los factores asociados a las muertes hospitalarias por artroplastias de cadera en el Sistema Único de Salud (SUS), en el Estado de Rio de Janeiro, Brasil. Se realizó un estudio transversal utilizando el Sistema de Información Hospitalaria del SUS, considerando hospitalizaciones y muertes por artroplastias de cadera ocurridas entre 2016-2018. Los análisis consideraron las hospitalizaciones según la naturaleza de la atención (electiva, urgencia y accidentes o lesiones e intoxicaciones). Se realizó una regresión logística binaria para obtener la razón de probabilidad de muerte. La mortalidad aumentó según la gravedad de la hospitalización. La mayoría de las hospitalizaciones con muerte se debió a la fractura de fémur, y requirió cuidados intensivos, tiempo promedio de estancia de 21,5 días, correspondió a mujeres de 80 años o más, de raza/color blanca, a quienes se sometió al procedimiento en unidades habilitadas de alta complejidad en ortopedia y traumatología, municipal y clasificadas como general II, ubicadas en la región de residencia del usuario. La probabilidad de muerte se mostró significativa para la edad del usuario, el uso de la unidad de cuidados intensivos (UCI) y la estancia hospitalaria. Se espera que la demanda de artroplastias de cadera y rehabilitación física aumente a medida que la población envejece. Los equipos de salud deben estar preparados para atender a una población que envejece. El conocimiento de los factores que incrementan el riesgo de muerte favorece la planificación y el manejo del cuidado por parte del equipo hospitalario, incluso en el sentido de reducir la estancia hospitalaria, que tanto afecta la condición funcional de la persona mayor.

Ações judiciais por artroplastia de quadril no Estado do Rio de Janeiro, Brasil, 2016-2018 / Legal claims to obtain hip replacement surgery in the State of Rio de Janeiro, Brazil, 2016-2018 / Acciones judiciales por artroplastia de cadera en el Estado de Río de Janeiro, Brasil, 2016-2018

Analisar as características processuais, médico-sanitárias e dos demandantes das ações por artroplastia de quadril, ajuizadas contra os entes públicos no Estado do Rio de Janeiro, Brasil, de 2016 a 2018. Realizou-se um estudo retrospectivo, cujo objeto foi ações por artroplastia de quadril, ajuizadas contra os entes públicos no Estado do Rio de Janeiro, localizadas na base de dados do Sistema Estadual de Regulação e do Núcleo de Apoio Técnico do Judiciário do Tribunal de Justiça do Rio de Janeiro (NAT-JUS), protocoladas entre janeiro de 2016 e dezembro de 2018. A análise dos dados se deu por segmento de justiça. Foram localizadas 89 ações judiciais por artroplastia de quadril. A maioria foi ajuizada na Justiça estadual, contou com litisconsórcio passivo, foi impulsionada pela Defensoria Pública, teve o pedido de antecipação de tutela deferido e o pedido considerado procedente, e não houve interposição de recurso à sentença. Mais da metade das ações foram encaminhadas ao NAT-JUS. O grupo de usuários com doenças osteodegenerativas esperou aproximadamente sete meses, enquanto o grupo com agravos de natureza emergencial aguardou quase dois meses para a realização do procedimento, desde a data de distribuição da ação judicial. As ações judiciais por artroplastia de quadril mostraram semelhanças e diferenças em relação a outros pleitos, objeto de outros estudos, o que pode exigir estratégias específicas para sua qualificação. O acesso à artroplastia de quadril, por via judicial, no Sistema Único de Saúde (SUS) no Estado do Rio de Janeiro encontra-se prejudicado, entendendo as demandas como referência de necessidades não atendidas.

This study analyzed the court proceedings, health characteristics of the patients, and plaintiffs' characteristics in lawsuits for hip replacement surgery from public health services in the state of Rio de Janeiro, Brazil. The data employed was from the Technical Support Center for the Judiciary of the Rio de Janeiro Court of Justice (NAT-JUS) database, from January 2016 to December 2018. Data were analyzed according to tiers in the court system. There were 89 lawsuits filed for hip replacement surgery and most of them were tried in the Court of Justice of the State of Rio de Janeiro (TJRJ), with joint plaintiffs, represented by the Public Defender's Office. They had advance relief granted, and were ruled in favor of the plaintiffs, with no appeals filed. More than half of the cases were referred to NAT-JUS. The osteoarthritis group waited approximately seven months, while the emergency conditions group waited nearly two months from the date of filing to obtain the procedure. The lawsuits for hip replacement surgery showed similarities and differences in relation to other claims, object of others studies, which means that the strategies for their qualification. The study found that access to hip replacement surgery related to lawsuits in the Brazilian Unified National Health System (SUS) in the State of Rio de Janeiro is jeopardized, with the claims considered as an indicator of unmet needs

Analizar las características procesuales, médico-sanitarias y de los demandantes de las acciones por artroplastia de cadera, judicializadas contra entes públicos en el estado de Río de Janeiro, Brasil, de 2016 a 2018. Se realizó un estudio retrospectivo, cuyo objeto fueron acciones por artroplastia de cadera, judicializadas contra entes públicos en el estado de Río de Janeiro, localizadas en la base de datos del Sistema Estatal de Regulación y del Núcleo de Apoyo Técnico del Poder Judicial del Tribunal de Justicia de Río de Janeiro (NAT-JUS), protocolizadas entre enero de 2016 y diciembre de 2018. El análisis de los datos se dio por segmento de justicia. Se localizaron 89 acciones judiciales por artroplastia de cadera. La mayoría fueron judicializadas en la justicia estatal, contó con litisconsorcio pasivo, fue impulsada por la Defensoría Pública, tuvo la petición de anticipación de tutela diferida y la petición considerada procedente, y no existió interposición de recurso a la sentencia. Más de la mitad de las acciones se dirigieron al NAT-JUS. El grupo de usuarios con enfermedades osteodegenerativas esperó aproximadamente siete meses, mientras el grupo con agravios de naturaleza urgente aguardó casi dos meses para la realización del procedimiento, desde la fecha de distribución de la acción judicial. Las acciones judiciales por artroplastia de cadera mostraron semejanzas y diferencias, en relación a otros pleitos, objeto de otros estudios, lo que puede exigir estrategias específicas para su cualificación. El acceso a la artroplastia de cadera en el SUS relacionado a las demandas judiciales en el estado de Río de Janeiro se encuentra perjudicado, entendiendo las demandas como hitos de necesidades no atendidas.

Abordaje anterior de la cadera: historia y beneficios / Anterior Approach to the Hip: History and Benefits

La artroplastia de cadera es uno de los tratamientos quirúrgicos más exitosos en la cirugía ortopédica. Actualmente existe un mayor interés en el abordaje anterior para artroplastias de cadera determinado por la creencia de que al ser intermuscular puede provocar una disminución del dolor, una recuperación más rápida, mejor estabilidad de la cadera y menor riesgo de luxación después de la cirugía comparativamente. Es propósito de este artículo revisar la historia del abordaje anterior de la articulación de la cadera, su vía intermuscular de acceso y los principales beneficios que posee. Popularizado por Smith-Petersen en 1917, el abordaje anterior de la cadera debe su primera referencia escrita a Carl Hueter. Todos los abordajes de la cadera han demostrado ser seguros y eficaces, con ventajas y desventajas. Se requieren estudios a largo plazo de un mayor número de pacientes para demostrar un beneficio de costo y una mayor calidad en la atención médica(AU)

Hip replacement is one of the most successful surgical treatments in orthopedic surgery. There is currently greater interest in the anterior approach to hip arthroplasties determined by the belief that being intramuscular it can lead to less pain, faster recovery, better hip stability and comparatively less risk of dislocation after surgery. The purpose of this article is to review the history of the anterior approach to the hip joint, its intramuscular access route and its main benefits. Popularized by Smith-Petersen in 1917, the anterior approach to the hip owes its first written reference to Carl Hueter. All hip approaches have been shown to be safe and effective, with advantages and disadvantages. Long-term studies of larger numbers of patients are required to demonstrate cost benefit and higher quality of medical care(AU)

Factores de riesgo de luxación en una serie de 2732 prótesis totales de cadera / Risk Factors for Dislocation in a Series of 2732 Total Hip Replacements

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)
