ABSTRACT

Objetivo: caracterizar desde el punto de vista microbiológico las infecciones periprotesicas (IP) de los pacientes sometidos a remplazo articular de rodilla o cadera, en la IPS universitaria Clínica León XIII, y evidenciar los patrones más comunes de resistencia a los antibióticos, en el periodo 2015-2018. Metodología: se recolectó información de 25 pacientes llevados a remplazo articular de rodilla o cadera en la IPS universitaria, sede Clínica León XIII, durante el periodo de 2015-2018, que desarrollaron IP. Se obtuvo información sobre características demográfica, clínicas y patrones de resistencia (según antibiograma), y sobre los criterios usados para diagnosticarla. Los datos se registraron, según la naturaleza y distribución de la variable, en medias o medianas para las variables cuantitativas, y en frecuencias para las cualitativas. Resultados: entre 2015 y 2018 se realizaron 541 remplazos articulares, la incidencia de infección periprotésica fue de 4.6% (25 pacientes), 22 casos (88%) con crecimiento microbiológico. El germen más frecuente fue el S. aureus, con patrón alto de resistencia para meticilina (SAMR), en el 44%. Seguido por K. pneumoniae, con un patrón de resistencia por producción de betalactamasas de espectro extendido (BLEE) de 83%. Ninguno tuvo resistencia a los carbapenémicos. Conclusiones: los resultados son similares a los reportados en la literatura internacional. Sigue siendo el S. aureus el principal causante de la infección periprotésica, seguido de los gérmenes gram negativos.


Objective: to microbiologically characterize the periprosthetic infections (PI) of patients undergoing knee or hip joint replacement at IPS Universitaria Clínica León XXIIIin the period 2015-2018, and to demonstrate the most common antibiotic resistance patterns. Methodology: the information was collected from 25 patients undergoing knee or hip joint replacement at IPS Universitaria Clínica León XXIII during the period 2015-2018 who developed PI. Data was obtained on demographic, clinical characteristics, and antibiotic resistance patterns (according to antibiograms), as well as on the diagnostic criteria used to diagnose it. The data was recorded, according to the nature and distribution of the variable, in means or medians for the quantitative variables, and in frequencies for the qualitative variables.Results:between 2015-2018, 541 joint replacements were performed. There was an incidence of periprosthetic infection in 25 patients (4.6%), 22 of whom (88%) had micro-biological growth. The most frequent germ was S. aureus, which had a high resistance pattern for methicillin-resistant S. aureus (MRSA) in 44%, followed by K. pneumoniaewith a positive extended spectrum beta-lactamase (ESBL) in 83%. None of them showed resistance to carbapenems.Conclusions: the results found are similar to those reported in the international lite-rature. This investigation evidenced that S. aureus continues to be the main cause of periprosthetic infection, followed by gram-negative germs.

ABSTRACT

Abstract Objective The aim of our study is to analyze the clinical and functional results obtained using autologous chondrocytes embedded in a fibrin scaffold in knee joint injuries. Methods We included 56 patients, 36 men and 20 women, with a mean age 36 years. Six of the patients were professional athletes, with single knee injuries that were either chondral or osteochondral (43 chondral, 9 osteochondral, 2 cases of osteochondritis dissecans and 2 osteochondral fractures), 2 to 10 cm2 in size and ≤ 10 mm deep, with no signs of osteoarthritis. The location of the injury was in the patella (8), the medial femoral condyle (40) and lateral femoral condyle (7) and one in the trochlea. The mean follow-up was 3 (range: 1-6) years. The clinical course was assessed using the Cincinnati and Knee Injury and Osteoarthritis Outcome (KOOS) scores, 6 and 12 months after surgery. The paired Student t-test was used to compare pre-and postoperative results. Results Six months after the implant, patients resumed their everyday activities. On the assessment scores, their condition was improving in comparison with their presurgical state (p < 0.05). They were also able to carry out their sporting activities more easily than prior to surgery (p < 0.05). Conclusion The seeding of chondrocytes in fibrin may provide a favorable microenvironment for the synthesis of extracellular matrix and improved the clinical condition and activity of the patients 1 year after surgery.


Resumo Objetivo O objetivo do nosso estudo é analisar os resultados clínicos e funcionais do tratamento de lesões nas articulações do joelho com condrócitos autólogos embebidos em arcabouço de fibrina. Métodos O estudo foi realizado com 56 pacientes (36 homens e 20 mulheres) com idade média de 36 anos; 6 indivíduos eram atletas profissionais. Os pacientes apresentavam lesões únicas, condrais ou osteocondrais (43 condrais, nove osteocondrais, 2 casos de osteocondrite dissecante e duas fraturas osteocondrais) no joelho, com 2 a 10 cm2 de tamanho e ≤ 10 mm de profundidade, sem sinais de osteoartrite. As lesões estavam localizadas na patela (8), no côndilo femoral medial (40), no côndilo femoral lateral (7) e na tróclea (1). O período médio de acompanhamento foi de 3 anos (faixa de 1-6 anos). A evolução clínica foi avaliada pelos escores de Cincinnati e Knee Injury and Osteoarthritis Outcome (KOOS), 6 e 12 meses após a cirurgia. O teste t de Student pareado foi utilizado para comparação dos achados pré e pós-operatórios. Resultados Os pacientes retomaram suas atividades diárias 6 meses após o implante. Os escores avaliados demonstraram a melhora em comparação ao estado pré-cirúrgico (p < 0,05). Além disso, os pacientes conseguiram realizar suas atividades esportivas com mais facilidade do que antes da cirurgia (p < 0,05). Conclusão A cultura de condrócitos em fibrina pode proporcionar um microambiente favorável para a síntese de matriz extracelular e melhorar a condição clínica e a atividade dos pacientes 1 ano após a cirurgia

ABSTRACT

INTRODUCCIÓN. Los defectos de la fosa poplítea suponen un desafío reconstructivo para el cirujano plástico, dada la relación íntima de esta área con la articulación de la rodilla y la neurovasculatura vital subyacente. El propósito de éste informe fie compartir la experiencia en la utilización de un colgajo fasciocutaneode la arteria safena. CASO CLÍNICO. Paciente de 5 años de edad que sufrió quemadura térmica en miembros inferiores con dos años y medio de evolución, ameritó injertos, presentó contractura por tejido cicatricial en fosa poplítea, dificultó la deambulación y desarrollo neuro osteomuscular. Se realizó reconstrucción de la fosa poplítea con colgajo fasciocutáneo de la arteria safena. RESULTADOS. El colgajo fasciocutáneo de la arteria safena dio cobertura al defecto en fosa poplítea izquierda tras retiro del tejido cicatricial que producía contractura, limitaba la marcha y el desarrollo neuro osteo-muscular. Seis meses postquirúrgicos brindó cobertura cutánea definitiva y estable en el área crítica, que permitió la deambulación con movimientos de extensión y flexión de rodilla conservados. DISCUSIÓN. Este colgajo al igual que en otros estudios que respaldan su ejecución brindó excelentes resultados en defectos de partes blandas a nivel de la articulación de la rodilla. CONCLUSIÓN. El colgajo fasciocutáneo de la arteria safena demostró utilidad para la reconstrucción del defecto de la fosa poplítea, posibilitó una cobertura definitiva, funcional y estética, restableció los ángulos de movilidad y favoreció el desarrollo pondoestatural del paciente.


INTRODUCTION. Defects of the popliteal fossa pose a reconstructive challenge for the plastic surgeon, because of the intimate relation of this area with the knee joint and the near vital neurovasculature; the purpose of this report was to share the experience of using a fasciocutaneous flap of the saphenous artery. CLINICAL CASE. A 5 year old patient who suffered thermal burn in lower limbs with two and a half years of evolution, he nedeed grafts and presented tissue contracture because the scar in the popliteal fossa hindered ambulation and neuro-osteomuscular growth. Reconstruction of the popliteal fossa was made it with a fasciocutaneous flap of the saphenous artery. RESULTS. The fasciocutaneous flap of the saphenous artery covered the defect in the left popliteal fossa after removal of the scar tissue that caused contracture, limited to walk and growth. Six months after surgery the flap provided definitive and secure skin coverage in the critical area, which allowed to walk with preserved knee extension and flexion movements. DISCUSSION. This flap was useful for the recons-truction of the defect of the popliteal fossa and provided excellent results in soft tissue defects in this area of the knee joint. CONCLUSION. The fasciocutaneous flap of the saphenous artery proved useful for the reconstruction of the popliteal fossa defect, it permited a definitive, functional and esthetic coverage, reestablished the angles of mobility and helped with the patient growth

ABSTRACT

Abstract Objective Retrospectively assess the functional outcome of patients undergoing arthrodesis after septic failure of total knee arthroplasty. Methods Eighteen patients were evaluated, with a mean time of 3.7 years of follow-up. Arthrodesis surgery was performed using a narrow anterior dynamic compression plate, and medial or external fixator in two planes of the joint (Orthofix Bone Growth Therapy, Lewisville, TS, USA), at the surgeon's discretion. Results The most frequent pathogen found was Staphylococcus aureus methicillin sensitive (38.9%). The mean lower limb discrepancy was 3.63 cm. The mean knee society score was 68 points. According to the visual analog scale for pain, 44% of the patients had a 0 score at the time of assessment, and 22.2% were very dissatisfied, despite the bone healing achieved. Patients were assessed for the ability to walk with or without assistance. Conclusion Knee arthrodesis surgery was effective in controlling the infectious process and decreasing pain complaints, but satisfaction with the procedure was low.

ABSTRACT

Abstract Objective To evaluate knee alignment in the frontal plane and pelvic balance during the step-down test in female and male soccer players. Methods Cross-sectional study carried out with male and female soccer players from under-15 and under-17 teams of a professional club in Southern Brazil. The step-down test was performed, filmed with a video camera, and evaluated according to the angular measurements obtained during movement using the Kinovea software (open source), version 0.8.24. Results The sample consisted of 38 individuals, 19 males and 19 females. Female athletes had a greater varus angle (9.42º ± 1.65º) compared to male athletes (3.91º ± 2.0º; p = 0.04). There was no difference regarding the unilateral pelvic drop between the groups. In addition, the association between the hip-related pelvic drop and the projection angle on the frontal plane of the knee was weak in both genders. Conclusion Even though the pelvic drop was observed in both genders, young female athletes had greater varus knee angles on the step-down test, which require greater attention to minimize the risk of injury.


Resumo Objetivo Avaliar o alinhamento do joelho no plano frontal e o equilíbrio pélvico durante a descida de um degrau comparando atletas de futebol feminino e masculino. Métodos Estudo transversal, realizado com atletas de futebol das categorias sub-15 e sub-17, de ambos os sexos, de um clube profissional do Sul do Brasil. Foi realizado o teste de descida de um degrau, o qual foi filmado por uma câmera de vídeo, e, em sua avaliação, traçaram-se as medidas angulares durante o movimento por meio do software Kinovea (código aberto), versão 0.8.24. Resultados A amostra foi composta por 38 indivíduos, 19 do sexo masculino e 19 do sexo feminino. As atletas do sexo feminino apresentaram maior ângulo em varo (9,42º ± 1,65º) quando comparadas com os atletas masculinos (3,91º ± 2,0º; p = 0,04). Não houve diferença em relação à queda unilateral da pelve (drop pélvico) entre os grupos, e a associação entre o drop pélvico do quadril e o ângulo de projeção no plano frontal do joelho foi fraca em ambos os sexos. Conclusão Apesar de ambos os sexos terem apresentado queda pélvica, as atletas de base do sexo feminino apresentaram maior angulação do joelho em varo no teste de descida do degrau, e necessitam maior atenção para minimizar o risco de lesão.

ABSTRACT

Abstract The arthroscopic reconstruction of the anterior cruciate ligament is a common surgery performed by the orthopedic surgeons willing to restore the knee stability of physically active patients. Despite the fact that it is usually an uneventful procedure, surgeons must always look for better post-operative results; in this scenario, the arthroscopic reconstruction of the anterior cruciate ligament without a tourniquet is a promising alternative. The aim of the present paper is to share with other orthopedic surgeons around the world our experience with this procedure and some technical tips that may be helpful.


Resumo A reconstrução artroscópica do ligamento cruzado anterior é uma cirurgia comum realizada pelos cirurgiões ortopédicos dispostos a restaurar a estabilidade do joelho de pacientes fisicamente ativos. Apesar de ser geralmente um procedimento sem intercorrências, os cirurgiões devem sempre procurar melhores resultados pós-operatórios; neste cenário, a reconstrução artroscópica do ligamento anterior sem torniquete é uma alternativa promissora. O objetivo deste artigo é compartilhar com outros cirurgiões ortopédicos ao redor do mundo nossa experiência com este procedimento e algumas dicas técnicas que podem ser úteis.

ABSTRACT

INTRODUÇÃO: Existem várias escalas para avaliar as percepções subjetivas e os componentes individuais em indivíduos com osteoartrite (OA) de joelho. Até o momento, não há escalas disponíveis conhecidas para medir o equilíbrio combinado entre mobilidade, AVD e QV em OA de joelho com base na Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF). OBJETIVO: Gerar itens e domínios relacionados aos problemas enfrentados pelos indivíduos com OA de joelhos e validar o conteúdo por especialistas. MÉTODOS: Os domínios e itens foram gerados através de pesquisa bibliográfica extensa (ELS) para extrair itens relacionados a equilíbrio, mobilidade, ADL e QV em indivíduos com OA em joelhos baseados na CIF e através de entrevista aprofundada direta (EAD) em 13 pessoas com OA de joelhos e três especialistas. A validação de conteúdo dos domínios e itens gerados foi validada por 10 especialistas por meio da pesquisa Delphi online. O índice mínimo de validação de conteúdo em nível de item (I-CVI) de 0,80 foi considerado para validar os itens identificados e o índice de validação de conteúdo em nível de escala geral (S-CVI) de 0,90 foi fixado para validar os itens gerados para uso no processo de desenvolvimento da escala. RESULTADOS: Os 117 itens gerados por EAD na ELS foram inicialmente agrupados em 18 domínios. A validação de conteúdo pelo método Delphi resultou em uma diminuição para 56 itens agrupados em 14 domínios com SCVI de 0, 93. CONCLUSÃO: O conjunto abrangente de itens de deficiência, limitação de atividade e restrição de participação para indivíduos com OA de joelhos nos domínios propostos foi desenvolvido e o conteúdo validado. Esses itens são recomendados para uso no desenvolvimento de uma nova escala abrangente de índice de osteoartrite do joelho (CKOAI).


INTRODUCTION: There are several scales to evaluate subjective perceptions and individual components in individuals with knee osteoarthritis (IKOA). Till date, no scale is available to measure the combined balance, mobility, ADL and QoL in IKOA based on the International Classification of Functioning, Disability and Health (ICF). OBJECTIVE: The purpose of the study was to generate items and domains related to problems faced by IKOA and to validate the content by experts. METHODS: The domains and items were generated through extensive literature search (ELS) to extract items related to symptoms, balance, mobility, ADL and QoL in IKOA based on the International Classification of Functioning, Disability and Health (ICF) and through in-depth direct interview (IDDI) from 13 IKOA and three experts. The content validation of domains and items generated were validated by 10 experts through online Delphi survey. Minimum itemlevel content validation index (I-CVI) of 0.80 was considered to validate the identified items and the overall scale-level content validation index (S-CVI) of 0.90 was fixed to validate the generated items to use in scale development process. RESULTS: 117 items generated by IDDI and ELS were grouped under 18 domains initially. Content validation by Delphi method resulted in reduction with 56 item pool being grouped under the 14 domains with SCVI is 0.93. CONCLUSION: The comprehensive impairment, activity limitation and participation restriction item pool for IKOA under the proposed domains, have been developed and content validated. These items are recommended for their use in development of new comprehensive knee osteoarthritis index scale (CKOAI).

ABSTRACT

okenella regensburgei belongs to the family Enterobacteriaceae and is an opportunistic agent rarely associated with infections in humans. We report a case of osteoarticular knee infection caused by Y. regensburgei in a patient under treatment for rheumatoid arthritis, using corticosteroids, with complication in primary total arthroplasty of the knee. Y. regensburgei was identified using the VITEK2 system. Antimicrobial susceptibility testing was performed using the disk-diffusion method, according to the guidelines from the Clinical and Laboratory Standards Institute. The patient presented favorable clinical evolution after the second debridement, with complete removal of the prosthesis and antibiotic therapy with sulfamethoxazole/trimethoprim. This is the first case of Y. regensburgei infection described d in Brazil.

ABSTRACT

OBJECTIVES: To evaluate how transtibial amputation (TT) affects bodyweight distribution, voluntary knee joint position sense (JPS), and quadriceps (QUA) and hamstrings (HAM) strength in prosthetized patients. METHODS: Only TT patients who had been prosthetized for more than one year were included, and an age-paired able-bodied group was used as control. The participants stood on force plates with their eyes open to measure bodyweight distribution between the limbs. Knee voluntary JPS was assessed by actively reproducing a set of given arbitrary joint angles using a video analysis approach, and QUA and HAM strength were assessed isometrically with a hand-held dynamometer. RESULTS: Sixteen TT subjects (age: 39.4±4.8 years) and sixteen age-paired control subjects (age: 38.4±4.3 years) participated in the study. The amputees supported their bodyweight majorly on the sound limb (54.8±8.3%, p<0.001). The proprioceptive performance was similar between the amputated (absolute error (AE): 2.2±1.6°, variable error (VE): 1.9±1.6°, constant error (CE): -0.7±2.0°) and non-amputated limbs (AE: 2.6±0.9°, VE: 2.1±0.9°, CE: 0.02±2.3°), and was not different from that of control subjects (AE: 2.0±0.9°, VE: 1.4±0.4°, CE: -1.1±1.7°). There was a considerable weakness of the QUA and HAM in the amputated limb compared with the sound limb and control subjects (p<0.001 both). CONCLUSIONS: The asymmetric bodyweight distribution in the transtibial amputees was not accompanied by a reduction in knee proprioception. There was significant weakness in the amputated limb, which could be a potential issue when designing rehabilitation programs.

ABSTRACT

RESUMEN Introducción: El mieloma múltiple constituye una proliferación maligna de las células plasmáticas derivadas de un solo clon. El tumor, sus productos y la respuesta del paciente ocasionan diversos trastornos funcionales orgánicos y síntomas como dolores óseos o fracturas, insuficiencia renal, predisposición a infecciones, anemia, hipercalcemia y, en ocasiones, trastornos de la coagulación, síntomas neurológicos y manifestaciones vasculares de hiperviscosidad. Objetivo: Presentar un caso infrecuente teniendo en cuenta que la infección aguda como forma de presentación inicial de mieloma es poco usual. Presentación del caso: Se presenta un caso de un paciente de 61 años de edad, ingresado en el servicio de ortopedia en tres ocasiones diferentes y operado de artritis séptica de la rodilla izquierda en estas tres oportunidades. Se mantuvieron los elementos inflamatorios locales a nivel de la articulación, fiebre recurrente, anemia y eritrosedimentación acelerada. Conclusiones: Los estudios hematológicos específicos confirmaron el diagnóstico de mieloma múltiple. Se comenzó tratamiento de inducción a la remisión para esta enfermedad con melfalán y prednisona; se logró mejoría del cuadro infeccioso al concluir el primer ciclo de esta intervención terapéutica(AU)


ABSTRACT Introduction: Multiple myeloma constitutes a malignant proliferation of plasma cells derived from a single clone. The tumor, its products, and the patient's response cause various organic functional disorders and symptoms such as bone pain or fractures, kidney failure, predisposition to infections, anemia, hypercalcemia, and sometimes coagulation disorders, neurological symptoms, and vascular manifestations of hyperviscosity. Objective: To present a rare case, taking into account that acute infection as the initial presentation of myeloma is unusual. Case report: We report a case of a 61-year-old patient, admitted to the orthopedic service on three different occasions and operated on for septic arthritis of the left knee, in every occasions. The local inflammatory elements at the joint level, recurrent fever, anemia and accelerated erythrocyte sedimentation were still present. Conclusions: Specific hematological studies confirmed the diagnosis of multiple myeloma. Induction-to-remission treatment for this disease was started with melphalan and prednisone; improvement of the infection was achieved at the conclusion of the first cycle of this therapeutic intervention(AU)

ABSTRACT

Abstract Objective To investigate the incidence, mechanisms, types of injury, most affected anatomical regions, and factors leading to injuries in trail bikers. Methods This was an observational, retrospective study analyzing 47 trail bikers. Data were collected through application of a referenced morbidity survey (RMS), which included information on injuries and their mechanisms. Results The lesions with the highest incidence were abrasion and bruise. The most affected anatomical regions were the shoulders and knees. The most common injury mechanism was skidding or loss of traction. Conclusion Trail bikers are exposed to risk factors and, consequently, to falls; it is important to develop more protective equipment, especially for the shoulders and knees.

ABSTRACT

Abstract Objective To perform an anatomical study of the location of the infrapatellar branch of the saphenous nerve in relation to the structures of the knee. Methods An anatomical study was performed by dissection of 18 humans knees (9 right and 9 left knees). After exposure of the infrapatellar branch and its direct and indirect branches, they were then measured. We adopted a quadrant in the medial region of the knee delimited by two transversal planes as a parameter of the study. Results In 17 of the 18 knees (94.4%) studied, a single infrapatellar branch was observed. The infrapatellar branch emerged as fibers of the womb of the sartorius muscle in 17 of the 18 knees (94.4%). In relation to the branch, we observed that in 100% of the knees the infrapatellar branch had at least one primary branch, resulting in a superior branch and an inferior branch. In 9 limbs (50% of the cases) this branch occurred outside the proposed quadrant, and, in the remaining limbs, it occurred within the quadrant. Conclusion The infrapatellar saphenous nerve branch was found in all dissected knees, and, in 94.4% of the cases, it was of the penetrating type; in 100% of the cases, it originated two primary direct branches. The direct and indirect branches presented great variability regarding their path.


Resumo Objetivo Realizar um estudo anatômico da localização do ramo infrapatelar do nervo safeno em relação às estruturas do joelho. Métodos Estudo anatômico realizado por meio de dissecação de 18 joelhos (9 direitos e 9 esquerdos). Após a exposição do ramo infrapatelar e de seus ramos diretos e indiretos, seguiram-se as medidas deles. Como parâmetro do estudo, adotamos um quadrante na região medial do joelho delimitado por dois planos transversais. Resultados Em 17 dos 18 joelhos estudados (94,4%), observou-se um único ramo infrapatelar. O ramo infrapatelar emergia por entre as fibras do ventre do músculo sartório em 17 dos 18 joelhos (94,4%). Em relação à ramificação, observamos que em 100% dos joelhos o ramo infrapatelar apresentava pelo menos uma ramificação primária, resultando num ramo superior e em outro inferior. Em 9 membros (50% dos casos), esta ramificação ocorria fora do quadrante proposto, e, no restante, dentro do quadrante. Conclusão O ramo infrapatelar do nervo safeno foi encontrado em todos os joelhos dissecados e, em 94,4% dos casos, ele era do tipo penetrante; em 100% dos casos, ele originava 2 ramos diretos primários. Seus ramos diretos e indiretos apresentaram grande variabilidade quanto ao trajeto.

ABSTRACT

RESUMEN Se presenta un caso de artritis séptica de rodilla por Pseudomonas stutzeri, bacilo gramnegativo aerobio ampliamente distribuido en la naturaleza y que rara vez ocasiona infecciones graves en el ser humano. Se trata de una mujer de 84 arios, hemodializada, que desarrolla una artritis séptica de rodilla derecha tras una inflitración con ácido hialurónico y que evoluciona favorablemente tras terapia antibiótica. Se debe tener en cuenta esta etiología cuando hay antecedentes de invasión local de la articulación y en estados de inmunosupresión tal y como sucede en nuestra paciente.


A B S T R A C T A case is presented of septic knee arthritis caused by Pseudomonas stutzeri, which is an aerobic gram-negative bacillus widely distributed in nature and rarely causes serious infections in humans. The patient is an 84-year-old woman on haemodialysis, who developed a septic arthritis of the right knee after a hyaluronic acid injection. There was a favourable outcome after antibiotic therapy. This aetiology should be taken into account when there is a history of local invasion of the joint and in states of immunosuppression, as occurred in this patient.

ABSTRACT

RESUMEN La hemorragia adrenal bilateral es un fenómeno poco común que puede acarrear consecuencias catastróficas por una crisis adrenal. Se ha asociado con diversas entidades como la sepsis, anticoagulación, neoplasias, el trauma, síndrome antifosfolípido y estado postoperatorio, especialmente, de cirugías ortopédicas. Su diagnóstico se dificulta en la medida en que los pacientes presentan signos y síntomas inespecíficos, por lo cual, una alta sospecha clínica es el principal indicador para la realización de una imagen que confirme el dictamen. Se presenta el caso de una hemorragia adrenal bilateral sin insuficiencia adrenal en una mujer de 71 años que, durante el quinto día del posoperatorio, tras una osteosíntesis de rodilla y recibiendo profilaxis antitrombótica con enoxaparina, ingresa al servicio de urgencias por dolor abdominal tipo cólico con 12 horas de evolución, acompañado de náuseas y sin signos de inestabilidad hemodinámica.


SUMMARY Bilateral adrenal hemorrhage is an uncommon phenomenon with potential catastrophic con-sequences, such as an adrenal crisis. It has been associated with diverse entities such as sepsis, anticoagulation, malignancy, trauma, antiphospholipid syndrome and postoperative setting, among others. The diagnosis is difficult as patients present with non-specific signs and symptoms, so high suspicion should trigger imaginological test to confirm the diagnosis. We report the case of bilateral adrenal hemorrhage without adrenal insufficiency that occurred in a 71-year-old woman during her fifth postoperative day after knee osteosynthesis, who received treatment with enoxaparin as antithrombotic prophylaxis and who presented to the emergency room for 12 hours of colic-like abdominal pain accompanied by nausea without signs of hemodynamic instability.

ABSTRACT

Abstract Objective To compare the plantar pressure distribution and the kinematics of the rearfoot on the stance phase of subjects with or without patellofemoral pain syndrome (PFPS). Methods A total of 26 subjects with PFPS and 31 clinically healthy subjects, who were paired regarding age, height and mass, participated in the study. The plantar pressure distribution (peak pressure) was assessed in six plantar regions, as well as the kinematics of the rearfoot (maximum eversion angle, percentage of the stance phase when the maximum angle was reached, and percentage of the stance phase in which the rearfoot was in eversion). The data were analyzed by descriptive and inferential statistics, with a significance level of p≤ 0.05. Results The pressure on the six plantar regions analyzed and the magnitude of the maximum eversion angle of the rearfoot when walking on flat surfaces did not present differences among the subjects with PFPS. However, the PFPS subjects showed, when walking, an earlier maximum eversion angle of the rearfoot than the subjects on the control group, and stayed less time with the rearfoot in eversion. Conclusion The PFPS seems to be related to modifications on the temporal pattern on the kinematics of the rearfoot.


Resumo Objetivo Comparar a distribuição da pressão plantar e a cinemática do retropé durante a fase de apoio da marcha de sujeitos com e sem síndrome da dor patelofemoral (SDPF). Métodos Participaram 26 sujeitos com SDPF e 31 clinicamente saudáveis, pareados em idade, estatura e massa corporal. Foi avaliada a distribuição da pressão plantar (pico de pressão) em seis regiões plantares, e a cinemática do retropé (ângulo máximo de eversão do retropé, porcentagem da fase de apoio da marcha em que o ângulo é atingido, e porcentagem da fase de apoio em que o retropé permaneceu em eversão). Os dados foram analisados por meio da estatística descritiva e inferencial, com nível de significância de p≤ 0,05. Resultados A pressão nas seis regiões plantares analisadas e a magnitude do ângulo máximo de eversão do retropé durante a marcha em superfície plana não se mostrou diferente nos sujeitos com SDPF. No entanto, sujeitos com SDPF apresentaram, dentro do ciclo da marcha, ângulo máximo de eversão do retropé mais cedo do que sujeitos do grupo controle, e permaneceram menos tempo com o retropé em eversão. Conclusão A SDPF parece estar relacionada à alteração no padrão temporal na cinemática do retropé.

ABSTRACT

Abstract Objective The objective of the present study is to evaluate the impact evaluate the impact of an institutional protocol on a tertiary hospital for the prevention of venous thromboembolism in 2005 patients submitted to primary total knee arthroplasty (TKA). Methods Data from medical records of patients submitted TKA before (n= 1,115) and after (n= 890) the implementation of the institutional protocol, totaling 2,005 patients, were retrospectively reported. Demographics, comorbidities, and outcomes were analyzed. Results There was no significant change in the cases of deep venous thrombosis (DVT) (1.6% versus 2.4%; p= 0.211). There was an increase in cases of pulmonary embolism (PE) (0.2% versus 0.8% p= 0.049). Conclusion Despite the implementation of the prevention protocol, no reduction in the studied events was observed. The small global incidence makes further studies with larger series necessary to confirm or rule out these findings.


Resumo Objetivo O objetivo do presente estudo é avaliar o impacto de um protocolo institucional em um hospital terciário na prevenção do tromboembolismo venoso em 2.005 pacientes submetidos a artroplastia total primária de joelho. Métodos Os dados dos prontuários de pacientes submetidos a artroplastia total do joelho antes (n= 1.115) e após (n= 890) a implantação do protocolo institucional, totalizando 2.005 pacientes, foram relatados retrospectivamente. Dados demográficos, comorbidades e desfechos foram analisados. Resultados Não houve alteração significativa nos casos de trombose venosa profunda (TVP) (1,6% versus 2,4%; p= 0,211). Houve um aumento nos casos de embolia pulmonar (EP) (0,2% versus 0,8%; p= 0,049). Conclusão Apesar da implementação do protocolo de prevenção, não houve redução nos eventos estudados. A pequena incidência global faz com que novos estudos, com séries maiores, sejam necessários para confirmar ou descartar esses achados.

ABSTRACT

Abstract Introduction: Pain control in total knee arthroplasty (TKA) is a determining factor in the patient's rehabilitation process. With conventional peripheral blocking techniques for the posterior compartment, foot drop, and distal motor deficit have been reported. The infiltration between popliteal artery and capsule of the knee (IPACK) block is a promising emerging analgesic technique. Objective: To describe analgesic control, opioid consumption, and mobility of patients scheduled for TKA using IPACK block as adjunct analgesic to the femoral block. Methods: We conducted a prospective observational cohort study over a 6-month period in adults taken to TKA. Sociodemographic and anthropometric characteristics, laterality, postoperative pain, and opioid consumption, patient and surgeon satisfaction (Likert), postoperative nausea and vomiting, and walk in the first 24hours, were evaluated and reported with a descriptive analysis. Results: Twenty-seven patients taken to TKA received an IPACK block. The pain score remained in a mild level during the 48 hours of evaluation. In 73% of the cases, an opioid rescue dose was not required; 81% of the patients managed to walk in the first 24 hours. Conclusion: The IPACK block, combined with femoral block and neuraxial anesthesia, turn out to be an excellent analgesic strategy for TKA, achieving adequate pain management, prompt rehabilitation, and early ambulation of the patient.


Resumen Introducción: El control del dolor en artroplastia total de rodilla (ATR) es determinante en el proceso de rehabilitación del paciente. Con las técnicas convencionales de bloqueo periférico para el compartimiento posterior se ha reportado pie caído y déficit motor distal. Por lo anterior, se decidió evaluar en una cohorte las cualidades analgésicas del bloqueo IPACK como una técnica emergente prometedora. Objetivo: Describir el control analgésico, consumo de opioides y movilidad de pacientes programados para ATR usando bloqueo IPACK como adyuvante analgésico al bloqueo femoral. Métodos: Se realizó un estudio de cohorte prospectivo, en adultos llevados a ATR, durante 6 meses. Se evaluaron las características sociodemográficas, antropométricas, lateralidad, dolor postopera torio y consumo de opioides, satisfacción del paciente y del cirujano, náuseas y vómito postoperatorio, caminata en las primeras 48 h. Se informar los resultados de forma descriptiva. Resultados: En total, 27 pacientes a quienes se les realizó ATR obtuvieron bloqueo IPACK. La puntuación del dolor se mantuvo en una escala leve en un rango de 1-3 durante las 48 horas de seguimiento. En el 73% de los casos no se requirió una dosis de opioide de rescate. El 81% de los pacientes logró caminar en las primeras 24 horas. Conclusión: El IPACK, combinado con el bloqueo femoral y la anestesia neuroaxial, resultan ser una excelente estrategia analgésica para logar un adecuado control del dolor en ATR, pronta rehabilitación y deambulación temprana del paciente.
