Comparative study of orthopaedic robot-assisted minimally invasive surgery and open surgery for limb osteoid osteoma / 中国修复重建外科杂志

OBJECTIVE@#To compare the accuracy and effectiveness of orthopaedic robot-assisted minimally invasive surgery versus open surgery for limb osteoid osteoma.@*METHODS@#A clinical data of 36 patients with limb osteoid osteomas admitted between June 2016 and June 2023 was retrospectively analyzed. Among them, 16 patients underwent orthopaedic robot-assisted minimally invasive surgery (robot-assisted surgery group), and 20 patients underwent tumor resection after lotcated by C-arm X-ray fluoroscopy (open surgery group). There was no significant difference between the two groups in the gender, age, lesion site, tumor nidus diameter, and preoperative pain visual analogue scale (VAS) scores ( P>0.05). The operation time, lesion resection time, intraoperative blood loss, intraoperative fluoroscopy frequency, lesion resection accuracy, and postoperative analgesic use frequency were recorded and compared between the two groups. The VAS scores for pain severity were compared preoperatively and at 3 days and 3 months postoperatively.@*RESULTS@#Compared with the open surgery group, the robot-assisted surgery group had a longer operation time, less intraoperative blood loss, less fluoroscopy frequency, less postoperative analgesic use frequency, and higher lesion resection accuracy ( P<0.05). There was no significant difference in lesion resection time ( P>0.05). All patients were followed up after surgery, with a follow-up period of 3-24 months (median, 12 months) in the two groups. No postoperative complication such as wound infection or fracture occurred in either group during follow-up. No tumor recurrence was observed during follow-up. The VAS scores significantly improved in both groups at 3 days and 3 months after surgery when compared with preoperative value ( P<0.05). The VAS score at 3 days after surgery was significantly lower in robot-assisted surgery group than that in open surgery group ( P<0.05). However, there was no significant difference in VAS scores at 3 months between the two groups ( P>0.05).@*CONCLUSION@#Compared with open surgery, robot-assisted resection of limb osteoid osteomas has longer operation time, but the accuracy of lesion resection improve, intraoperative blood loss reduce, and early postoperative pain is lighter. It has the advantages of precision and minimally invasive surgery.

Biopsia en ortopedia y riesgo de contaminación bacteriana durante el muestreo de tejidos: hechos y estrategias / Biopsy in orthopaedics and risk of bacterial contamination during tissue sampling: facts and strategies

Las biopsias en el campo de la ortopedia se utilizan para guiar las opciones de diagnóstico y tratamiento para el proceso de la enfermedad que puede estar ocurriendo. La preparación de la piel de estas biopsias sigue la preparación estándar para un procedimiento quirúrgico, con el objetivo de disminuir la cantidad de microbiota que podría conducir a la contaminación del tejido de la biopsia e incluso a una posible infección. El tejido obtenido de la biopsia a menudo se somete a un studio histopatológico y cultivo. La tasa de contaminación bacteriana informada es aproximadamente inferior al 4%. Esta revisión cuestiona si las muestras de las biopsias se contaminan con la microbiota que permanece en la piel y cómo puede afectar el manejo. Además, qué técnicas o pasos pueden disminuir la tasa de contaminación al realizar una biopsia. Nuestra revisión bibliográfica identificó pocos estudios sobre la contaminación bacteriana de las biopsias. Identificamos diferentes factores implicados en el conocimiento de la microbiota de la piel: técnicas y soluciones de preparación de la piel, variación de la microbiota típica que coloniza la piel según la región anatómica, retención preoperatoria versus administración profiláctica de antibióticos y uso de diferentes hojas de bisturí para la piel superficial y para tejidos profundos, entre otros. Aunque no pudimos identificar ningún dato que proporcionara respuestas a nuestra pregunta original y cuantificar cada factor individualmente, la mayoría de los estudios en diferentes campos ortopédicos proporcionaron hallazgos significativos hasta cierto punto. Describimos algunas recomendaciones prácticas basadas en el consenso y la efectividad teórica para disminuir la tasa de contaminación. Se necesitan más investigaciones en el campo de la ortopedia que impliquen la contaminación por microbiota de la piel de una biopsia

Biopsies in the field of orthopaedics are used to guide diagnostics and treatment options for the disease process that may be occurring such as a tumor or infection. Skin preparation of these biopsies follows the standard skin preparation for a surgical procedure, with the aim to decrease the amount of microbiota that could lead to contamination of the tissue biopsy and even possible infection. The tissue obtained from the biopsy often undergoes pathology and culture. The reported bacterial contamination rate is roughly below 4%. This review questions how samples from the biopsies are getting contaminated by microbiota that remains on the skin and how it affects infection management. In addition, which techniques or steps can decrease the rate of contamination when performing a biopsy. Our review identified little to no data on investigating bacterial contamination of biopsies. In doing this, the review identified different factors implicated in skin microbiota awareness: skin preparation techniques and solutions, variation of typical microbiota that colonize the skin based on the anatomical region, preoperative withholding versus administrating antibiotics prophylactically and using different scalpel blades for superficial and deep incisions, among others. Although we failed to identify any data that provided answers to our original question and quantify each factor individually, most studies in different orthopaedic fields provided significant findings to some extent. We outline some practical recommendations based on consensus and theoretical effectiveness in decreasing the contamination rate. Further research entailing skin microbiota contamination of a biopsy is needed in the field of orthopaedics.

Embarazo y ortopedia / Pregnancy and Orthopaedics

Introducción: Son múltiples las afecciones ortopédicas que sufre una mujer embarazada, por ello las demandas de atención por esta causa van en ascenso. Objetivo: Actualizar el tratamiento de las lesiones traumáticas y ortopédicas en la paciente embarazada y coordinar las indicaciones de la cesárea. Métodos: Se utilizan métodos teóricos y empíricos para realizar análisis del conocimiento actualizado sobre estas. Resultados: Se determinó que el parto normal es posible después de una fractura pélvica, siempre que no existan secuelas que dañen el canal del parto. El dolor de espalda fue un síntoma común en las mujeres embarazadas, pero en las que presentaron escoliosis las molestias fueron más frecuentes. La diastasis de la sínfisis del pubis se asoció con la maniobra de McRoberts; y la indicación de cesárea se sugirió a partir de criterios puramente obstétricos, aunque se respetaron las afecciones ortopédicas y traumáticas presentes en las pacientes. Conclusiones: Incrementar los conocimientos del personal que trabaja con la embarazada, a partir de sus factores de riesgo y las posibilidades de mitigación de daño por estas causas.

Introduction: pregnant women suffer from multiple orthopaedic conditions; therefore, care demands for this cause are on the rise. Objective: to update the treatment of traumatic and orthopaedic injuries in pregnant patients and coordinate the indications for cesarean section. Methods: theoretical and empirical methods were used to carry out the analysis of updated knowledge regarding these affections. Results: we determined that normal delivery is possible after a pelvic fracture, as long as there are no sequelae that damage the birth canal. Back pain was a common symptom in pregnant women but in those with scoliosis the discomfort was more frequent. Symphysis pubis diastasis was associated with the McRobert's maneuver; and the indication for cesarean section was suggested based on purely obstetric criteria, although the orthopaedic and traumatic conditions present in the patients were respected. Conclusions: to increase the knowledge of the personnel, who work with the pregnant women, based on their risk factors and the possibilities of mitigating damage due to these causes.

Core Competencies Self-Assessment and Patient-Practitioner Orientation during the First Year of a Brazilian Orthopedic Residency / Autoavaliação de competências fundamentais e orientação médico durante o primeiro ano de residência ortopédica brasileira

Abstract Objective Training a competent physician requires to direct the resident profile of graduate students for practice activities. We sought to identify the doctor-patient relationship orientation and the self-assessment of the core competencies, which they pointed out needed to be developed. Methods All 56 orthopedic residents admitted between 2016 and 2019 participated in the present prospective observational study. The Patient Practitioner Orientation Scale (PPOS) and a self-assessment questionnaire were answered at the beginning and end of the first year of residency (R1) in Orthopedics and Traumatology. We calculated mean and standard deviation for PPOS items and scores and analyzed them through the paired t-test. Self-Assessment Questionnaire answer options were "yes" or "I need to improve it" and skills were classified in decreasing order of the frequency of "I need to improve it" responses with description of absolute number and percentage. We compared frequencies using Fisher Test. P-values < 0.05 were considered statistically significant. GraphPad Prism 8.4.3 (GraphPad Software, San Diego, CA, USA) and Microsoft Excel (Microsoft Corporation, Redmond, WA, USA) were used for statistical analysis. Results In the period between the beginning and the end of R1, the total PPOS mean score significantly decreased from 4.63 to 4.50 (p= 0.024), more biomedical-focused. Around one-third of the residents identified competencies of patient care, practice-based learning and improvement, and interpersonal and communication skills as needed to improve. Conclusions The PPOS and self-assessment activities could promote reflection practices and are possible tools for learner-centered competency assessment. Biomedical guidance tends to prevail as the training of physicians progresses, and periodic self-assessments can be worked on to build a growth mindset.

Resumo Objetivo A formação de um médico competente requer direcionar o perfil de pós-graduação residente para atividades práticas. Buscou-se identificar a orientação de relacionamento médico-paciente e a autoavaliação das competências fundamentais que eles apontaram que precisavam ser desenvolvidas. Métodos Todos os 56 residentes em ortopedia admitidos entre 2016 e 2019 participaram do presente estudo observacional prospectivo. A Escala de Orientação Médico-Paciente (Patient Practitioner Orientation Scale [PPOS, na sigla em inglês]) e um questionário de autoavaliação foram respondidos no início e no final do primeiro ano de residência (R1) em Ortopedia e Traumatologia. Calculamos o desvio médio e padrão para itens e pontuações de PPOS e os analisamos através do teste t emparelhado. As opções de resposta do Questionário de Autoavaliação foram "sim" ou "preciso melhorar" e as habilidades foram classificadas na ordem decrescente da frequência das respostas "preciso melhorar" com descrição de número absoluto e percentual. Comparamos frequências usando o teste de Fisher. Consideramos significativos valores-p < 0,05. Os programas GraphPad Prism 8.4.3 (GraphPad Software, San Diego, CA, EUA) e Microsoft Excel (Microsoft Corporation, Redmond, WA, EUA) foram utilizados para análise estatística. Resultados No período entre o início e o final do R1, a média total de PPOS diminuiu significativamente, de 4,63 para 4,50 (p= 0,024), mais focada em biomédica. Cerca de um terço dos residentes identificou competências do cuidado ao paciente, aprendizagem e melhoria baseadas na prática e habilidades interpessoais e de comunicação, como necessitando melhorar. Conclusões As atividades de PPOS e autoavaliação podem promover práticas de reflexão e são possíveis ferramentas para avaliação de competência centrada no aluno. A orientação biomédica tende a prevalecer à medida que a formação dos médicos progride e as autoavaliações periódicas podem ser trabalhadas para construir uma mentalidade de crescimento.

Telemedicine Effectiveness in the First Elective Orthopedic Care Compared to a Standard Face-to-face Visit / Efetividade da teleconsulta no primeiro atendimento ortopédico eletivo comparada ao padrão presencial

Abstract Objective The study aimed to compare whether the diagnoses of orthopedic diseases at telemedicine (TM) consultations are the same as those established at face-to-face visits. Method Primary, observational, prospective, analytical study, with subjects from the local municipal network who were referred to the orthopedics outpatient clinic from May to June 2021. Subjects underwent two assessments: a telemedicine (TM) consultation and a face-to-face (FF) visit. Two different physicians attended to the patients and established a diagnosis. The physician performing the FF visit was not aware of the previous diagnoses. We compared the diagnoses obtained at both modalities to assess the degree of similarity. In addition, we determined the time required for consultations and the degree of satisfaction of the physicians. Results We evaluated 43 patients and seven physicians, totaling 44 TM and 43 FF visits. The diagnostic similarity index was 81.4%. TM consultations were shorter (mean time, 4.8 minutes) than FF visits. Physicians were less satisfied with TM in the four criteria evaluated (respective scores of 79.1, 23.3, 46.6, and 37.2). Conclusion TM consultations have a diagnoses agreement higher than 80% compared with FF visits. On the other hand, TM consultations were faster, and physicians were less satisfied with them in comparison with FF visits.

Resumo Objetivo O objetivo do estudo foi comparar se os diagnósticos das doenças ortopédicas realizados por teleconsulta (TC) são os mesmos dos atendimentos presenciais. Método Estudo primário, observacional, prospectivo, analítico, com dados colhidos de maio a junho de 2021, com participantes provenientes da rede municipal local que foram encaminhados ao ambulatório de ortopedia de referência e oferecida participação no estudo com duas avaliações: a primeira por teleatendimento e a segunda de forma presencial. Cada participante foi atendido por dois diferentes profissionais, e cada um emitiu um diagnóstico. Os profissionais do atendimento presencial não conheciam os diagnósticos prévios. Os diagnósticos emitidos foram comparados para avaliar o grau de semelhança. Ainda, foi aferido o tempo para realização dos atendimentos e o grau de satisfação do profissional participante. Resultados Foram avaliados 43 pacientes e 07 profissionais participaram, totalizando 44 TC e 43 atendimentos presenciais. O índice de semelhança do diagnóstico foi de 81,4%. A TC teve um tempo menor para realização (média de 4,8 minutos), que o presencial. A satisfação dos profissionais foi menor na TC nos quatro critérios avaliados, sendo, respectivamente, 79,1, 23,3, 46,6 e 37,2. Conclusão A TC tem concordância no diagnóstico superior a 80% em comparação ao atendimento presencial. Já a realização do teleatendimento teve menor tempo de duração e os profissionais se consideraram menos satisfeitos em relação ao atendimento presencial.

Percutaneous Suspensory Stabilization of Chronic Distal Radioulnar Joint (DRUJ) Dislocation Using an Adjustable Loop Endobutton Construct: Case Report / Fixação suspensiva percutânea de luxação crônica da articulação radioulnar distal (ARUD) usando um dispositivo de endobutton de laço ajustável: Relato de caso

Abstract Chronic distal radioulnar joint (DRUJ) dislocation has been treated historically with complex osteotomies and reconstructive procedures, often resulting in intractable stiffness and loss of function. It is desirable to use a technique of fixation that will not only restore the wrist biomechanics but also be cosmetically appealing to the individual. We present a novel technique of reduction and fixation of a chronically dislocated DRUJ in a 26-year-old male using a minimally invasive approach, with successful restoration of DRUJ function and no postoperative complications.

Resumo Luxação crônica da articulação radioulnar distal (ARUD) foi tratada historicamente com osteotomias complexas e procedimentos reconstrutivos, geralmente resultando em rigidez intratável e perda de função. É desejável usar uma técnica de fixação que não apenas restaure a biomecânica do punho, mas também seja esteticamente atraente para o indivíduo. Apresentamos uma nova técnica de redução e fixação de uma ARUD deslocada cronicamente em um homem de 26 anos, usando uma abordagem minimamente invasiva, com restauração bem-sucedida da função da ARUD e sem complicações pós-operatórias.

Comparison of faculty and student evaluations of the hybrid teaching of orthopedics during the COVID-19 pandemic

Background@#In the face of the COVID-19 pandemic and a country-wide lockdown, the University of the Philippines College of Medicine halted face-to-face teaching in exchange for online learning for its students. For the Learning Unit VI students, clinical rotations shifted to hybrid activities to continue learning activities while minimizing exposure risk. The Philippine General Hospital Department of Orthopedics introduced the following hybrid activities in its curriculum for Learning Unit VI students: 1) Online Lectures, 2) Online Departmental Conference, 3) Online Division Rounds, 4) Online SGDs, 5) Written Case, 6) Online Exams, 7) Preceptorship, Demo, Return Demo, and 8) Online OSCE. The department used a variety of platforms including synchronous sessions, asynchronous pre-recorded lectures, and face-to-face teaching, as appropriate. @*Objectives@#The study compared the faculty and student course evaluations of activities in the hybrid ORTHO 251 course. @*Methodology@#Faculty and students were asked to evaluate each activity according to the Course Evaluation By Students (CEBS), the standard questionnaire used by the college, to determine the overall rating of each activity as well as any differences between the two groups. @*Results@#The hybrid activities conducted in the ORTHO 251 course were rated as good or excellent by the faculty and students, with differences in a few activities. Consultants rated online exams as being less effectively integrated and that there was inadequate time allotment for online SGDs, written cases, and online exams. Meanwhile, students rated all activities higher in terms of stimulating self-directed learning. @*Conclusion@#With good to excellent outcomes, this study found that it has at least satisfactorily matched the learning platform to the learning component. While knowledge may be taught via asynchronous recorded lectures or reading materials, attitude and thinking processes are better formed through synchronous discussion. Skills in medical education, including Orthopedics, are still best taught via face-to-face demoreturn demo. With this information, the department can investigate the causes of these differences and improve on the identified weaknesses.

Intervention effect of injury control orthopedic strategy on fat embolism syndrome associated with long shaft fracture of lower limb / 中国骨伤

OBJECTIVE@#To observe the intervention effect of damage control orthopaedic(DCO) strategy on fat embolism syndrome(FES) associated with long shaft fracture of lower limbs.@*METHODS@#Retrospective analysis was made on the clinical data of 163 patients with FES associated with lower limb long shaft fractures admitted from January 2015 to May 2021. They were divided into two groups based on the time point of implementing DCO strategy in January 2018. Total of 92 patients were admitted from January 2015 to December 2017 as the control group, and other 71 patients were admitted from January 2018 to May 2021 as the intervention group. The hospital mortality, arterial oxygen saturation (SaO2), arterial partial pressure of oxygen (PaO2) and oxygenation index (OI), hemoglobin (Hb), platelet count(PLT), Harris score of hip joint, HSS score of knee joint, AOFAS score of ankle joint, clinical efficacy and complications were observed and compared between two groups.@*RESULTS@#Total of 163 patients were followed up for 12 to 18 months with an average of (16.91±1.22) months. The in-hospital mortality rate in the intervention group was 2.82% (2/71), and that in the control group was 16.30% (15/92), the difference between two groups was statistically significant(χ2=6.455, P<0.05). After the intervention, SaO2, PaO2 and OI in two groups were higher than those before the intervention(P<0.05), and after the intervention, SaO2, PaO2 and OI in two groups were statistically significant(P<0.05). Hb and PLT in two groups after intervention were higher than those before intervention (P<0.001), and there was statistically significant difference in Hb and PLT between two groups after intervention (P<0.05). The Harris score of hip joint, HSS score of knee joint and AOFAS score of ankle joint in both groups after 3 months of treatment were better than those before treatment (P<0.05). The total clinical effective rate of the intervention group was higher than that of the control group(χ2=4.194, P<0.05). The total incidence of complications in the intervention group was lower than that in the control group(χ2=4.747, P<0.05).@*CONCLUSION@#DCO strategy is helpful to reduce the in-hospital mortality of patients with FES associated with long shaft fracture of lower extremities, eliminate FES symptoms and stabilize vital signs, gain time advantage for phase Ⅱ definitive surgery, and has significant clinical intervention effect, which is worth popularizing.

However,in contrast to the widespread use of navigation technology in arthroplasty,orthopaedic tumor,and spine surgery,its application in orthopaedic trauma is relatively less. In this manuscript,the main purpose is to introduce the technical principles of navigation devices,outline the current clinical application of navigation systems in orthopaedic trauma,analyze the current challenges confronting its further application in clinical practice and its prospect in the future.

Epidemiological study of the prevalence of low back pain in spine surgeons in brazil / Estudo epidemiológico da prevalência de lombalgia em cirurgiões de coluna no brasil / Estudio epidemiológico de prevalencia de lumbalgia en cirujanos de columna en brasil

ABSTRACT: Introduction: Low back pain is defined as pain, muscle spasm, or stiffness between the L1 and L5 vertebrae, below the lower margin of the twelfth rib and above the upper gluteal fold, and may or may not be associated with pain radiating to the lower limbs. Objective: To determine the prevalence of low back pain in spine surgeons. Method: A non-randomized quantitative cross-sectional clinical study was carried out in a sample of 95 spine surgeons in Brazil, with the application of the Oswestry and visual analog pain scales, in addition to a structured questionnaire for the characterization of the participants. Results: Among the studied population, 69.5% were orthopedists, 30.5% were neurosurgeons, and the mean age of the sample was 46 years (±10.6), with neurosurgeons being older than orthopedists. Regarding BMI, the majority (77.8%) were overweight or obese, and seventy-six percent performed physical activity. The prevalence of low back pain was 58.9%. No relevant differences were found in the time spent weekly in surgeries between those who had low back pain and those who did not (p = 0.364). Mean pain intensity was 2.0 (SD = 2.2), statistically (p = 0.025) higher in orthopedists (2.3) when compared to neurosurgeons (1.3). Regarding the ODI score, 98.2% of the surgeons had a minimal disability (0-20%) for daily activities. Conclusion: The prevalence of low back pain in spine surgeons is high and is associated with mild inability to perform daily activities.

Epidemiological profile in a tertiary admission unit of spine diseases / Perfil epidemiológico em uma unidade de internação terciária de doenças da coluna vertebral / Perfil epidemiológico en una unidad de internación terciaria de patologias de la columna vertebral

ABSTRACT: Introduction: In March 2020, WHO officially decreed that the world was going through a pandemic, that of Covid-19. In May 2022, in Brazil, the end of measures to deal with the pandemic was decreed. In 2022, there was a movement to return to normal care in the provision of care. Objective: In the present study, we carried out a retrospective descriptive analysis of the epidemiological scenario of the ward of the Spine Group at the Hospital das Clínicas of the Faculty of Medicine of the Universidade de São Paulo (HC-FMUSP). Method: Data analysis was performed from information gathered in patients' medical records. Results: In the analyzed period, there were 152 consultations in hospitalization, with the main cause being spinal trauma. Of all the cases, only 23.68% were scheduled on an elective basis, which despite being a lower than expected number, was shaped by the demands of urgent care channeled to the service in question. Conclusion: Despite a higher number of cases hospitalized in the post-pandemic period, there is still the expectancy of more elective cases to be treated in the future. Level of Evidence III; Retrospective Case Series Study.

RESUMO: Introdução: Em março de 2020, a OMS decretou oficialmente que o mundo atravessava uma pandemia, a Covid-19. Em maio de 2022, no Brasil, decretou-se o fim das medidas de enfrentamento à pandemia. No ano de 2022, houve um movimento de retorno à normalidade assistencial na prestação de atendimentos. Objetivo: No presente estudo, realiza-se uma análise retrospectiva descritiva do cenário epidemiológico da enfermaria do Grupo de Coluna Vertebral do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (HC-FMUSP). Método: A análise dos dados foi efetuada a partir do levantamento de prontuários médicos. Resultados: No período analisado, houveram 152 atendimentos em regime de internação, com a principal causa sendo o traumatismo da coluna vertebral. De todos os casos, apenas 23,68% foram casos agendados em regime eletivo, o que apesar de ser um número abaixo do esperado, foi moldado pelas demandas dos atendimentos de urgência canalizados ao serviço em questão.

Método: El análisis de los datos se realizó con acceso al prontuario médico de los pacientes. Resultados: En el período analizado, hubo 152 consultas en hospitalización, siendo la principal causa trauma espinal. Del total de casos, solo el 23,68% fueron programados de forma electiva que, a pesar de ser un número inferior al esperado, estuvo condicionado por las demandas de atención urgente canalizadas al servicio en cuestión. Conclusión: A pesar del aumento de asistencias en el período postpandemia, hay espacio para una mayor recuperación futura en el volumen de casos electivos. Nivel de Evidencia III; Estudio Retrospectivo de Serie de Casos.

Anterior lumbar interbody fusion (alif): epidemiological and radiological profile / Artrodese lombar anterior: perfil epidemiológico, radiológico / Artrodesis lumbar anterior: perfil epidemiológico, radiológico

ABSTRACT: Objective: Evaluate the epidemiological and radiographic data of patients submitted to the Anterior Lumbar Interbody Fusion (ALIF) technique and the possible complications related to this procedure. Methods: A longitudinal and retrospective study was carried out to analyze electronic medical records and image files of patients who underwent spinal surgery using the ALIF technique between February 2019 and January 2021. Epidemiological data such as age, gender, and level of surgery were analyzed. Radiographic evaluations of lumbar lordosis from L1 to S1 were performed using the COBB technique and the anterior and posterior height of the disc space. The presence of intraoperative and postoperative complications in the patients was analyzed. Results: Initially, 70 patients were analyzed. The most prevalent operated level was L5-S1. The length of stay of the patients varied between 36 and 72 hours. Intraoperative bleeding ranged from 20mL to 400mL. Three patients had significant venous lesions. Differences between anterior and posterior lordosis and height measurements were significant (p < 0.001). Lordosis had a mean increase of 10.3°, anterior height had a mean increase of 7.9mm, and posterior height of 4.0mm. Six cases of intra and postoperative complications were observed. Conclusion: The patients showed improvement in the radiological parameters of the anterior and posterior height of the vertebral discs, with a significant increase in lumbar lordosis. Complication rates were 9.8%, and we had a short hospital stay. Level of Evidence II; Retrospective Longitudinal Study.

RESUMO: Objetivo: Avaliar os dados epidemiológicos e radiográficos de pacientes submetidos à técnica de Artrodese Lombar Anterior (ALIF) e avaliar as possíveis complicações relacionadas a este procedimento. Métodos: Realizou-se um estudo longitudinal e retrospectivo com análise dos prontuários eletrônicos e arquivos de imagem dos pacientes submetidos a cirurgia da coluna pela técnica de ALIF, no período entre fevereiro de 2019 e janeiro de 2021. Dados epidemiológicos como idade, sexo e nível de cirurgia foram analisados. Foram feitas avaliações radiográficas da lordose lombar de L1 a S1 através da técnica de COBB e da altura anterior e posterior do espaço discal. Foram analisados a presença de complicações intra e pós-operatórias dos pacientes. Resultados: Foram analisados inicialmente 70 pacientes. O nível operado mais prevalente foi L5-S1. O tempo de internamento dos pacientes variou entre 36 e 72 horas. O sangramento intraoperatório variou de 20mL a 400mL. Três pacientes apresentaram lesões venosas importantes. As diferenças entre as medidas de lordose e altura anterior e posterior foram significativas (p < 0,001). A lordose teve aumento médio de 10,3°, a altura anterior teve aumento médio de 7,9mm e a altura posterior de 4,0mm. Foram observados 06 casos de complicações intra e pós-operatórias. Conclusão: Os pacientes apresentaram melhora nos parâmetros radiológicos de altura anterior e posterior dos discos vertebrais, com um aumento da lordose lombar significativo. As taxas de complicações foram de 9,8 % e tivemos um curto período de internação hospitalar. Nível de Evidência II; Estudo Longitudinal e Retrospectivo.

RESUMEN: Objetivo: Evaluar los datos epidemiológicos y radiográficos de pacientes sometidos a la técnica de Artrodesis Lumbar Anterior (ALIF) y evaluar las posibles complicaciones relacionadas con este procedimiento. Métodos: Se realizó un estudio longitudinal y retrospectivo con análisis de historias clínicas electrónicas y archivos de imágenes de pacientes intervenidos de columna vertebral mediante la técnica ALIF, en el período comprendido entre febrero de 2019 y enero de 2021. Datos epidemiológicos como edad, sexo y nivel quirúrgico fueron analizados. Las evaluaciones radiográficas de la lordosis lumbar de L1 a S1 se realizaron mediante la técnica COBB y la altura anterior y posterior del espacio discal. Se analizó la presencia de complicaciones. Resultados: Se analizaron 70 pacientes. El nivel operado más prevalente fue L5-S1. El tiempo de estancia de los pacientes varió entre 36 y 72 horas. El sangrado intraoperatorio osciló entre 20 ml y 400 ml. Tres pacientes tenían lesiones venosas importantes. Las diferencias entre la lordosis anterior y posterior y las medidas de altura fueron significativas (p < 0,001). La lordosis tuvo un aumento medio de 10,3°, la altura anterior tuvo un aumento medio de 7,9 mm y la altura posterior de 4,0 mm. Se observaron seis casos de complicaciones intra y postoperatorias. Conclusiones: Los pacientes mostraron mejoría en los parámetros radiológicos de altura anterior y posterior de los discos vertebrales, con aumento significativo de la lordosis lumbar. Las tasas de complicaciones fueron del 9,8% y hubo una corta estancia hospitalaria. Nivel de Evidencia II; Estudio Longitudinal y Retrospectivo.
