Correlation of the sagittal balance with postural analysis of the pelvis and lumbar spine / Correlação do equilíbrio sagital e análise postural de pelve e coluna lombar

ABSTRACT Objective: Evaluate and correlate the sagittal balance parameters with the postural of the pelvis and lumbar spine. Methods: 80 individuals of both sexes, aged between 20 and 35 years, were evaluated. Biophotogrammetry was done with the SAPO software program. Measurements of the sagittal balance parameters were obtained by analyzing a lateral view panoramic radiography of the vertebral column, in which the anatomical points of reference were digitally marked. The calculation of the angles was done automatically by the Keops program. Results: In Keops assessment, 17.5% of the sample had high pelvic incidence angles (> 60°), 31.5% had low pelvic incidence angles (< 45°), and 51.2% had medium pelvic incidence angles (between 46° and 59°). SAPO showed 12,5% lordosis, 40% retroversion, and 47,5% normal curvature. In the right lateral view, pelvic incidence angle had a moderate and positive correlation with vertical alignment of the trunk and with vertical alignment of the body, and a negative and moderate correlation with horizontal alignment of the pelvis. Conclusion: Differences were found between vertical alignment measurements from the postural evaluation system (SAPO). A positive correlation was found between PI from Keops and pelvic anteversion from SAPO. Level of Evidence II; Prospective Study.

RESUMO Objetivo: Avaliar e correlacionar o equilíbrio sagital com parâmetros posturais da pelve e coluna lombar Métodos: Foram avaliados 80 indivíduos de ambos os sexos, com idade entre 20 e 35 anos. A biofotogrametria foi realizada com o software SAPO. As medidas dos parâmetros do equilíbrio sagital foram obtidas pela análise de uma radiografia panorâmica em perfil da coluna vertebral, na qual os pontos anatômicos de referência foram marcados digitalmente. O cálculo dos ângulos foi feito automaticamente pelo programa Keops. Resultados: Na avaliação Keops, 17,5% da amostra apresentavam ângulos de incidência pélvicos altos (> 60°), 31,5% tinham ângulos de incidência pélvicos baixos (< 45°) e 51,2% apresentavam ângulos de incidência pélvicos médios (entre 46° e 59°). O SAPO apresentou 12,5% de lordose, 40% de retroversão e 47,5% de curvatura normal. Na vista lateral direita, o ângulo de incidência da pelve apresentou correlação moderada e positiva com o alinhamento vertical do tronco e com o alinhamento vertical do corpo e negativa e moderada com o alinhamento horizontal da pelve. Conclusão: Foram encontradas diferenças entre as medidas de alinhamento vertical do sistema de avaliação postural (SAPO). Uma correlação positiva foi encontrada entre IP de Keops e anteversão pélvica de SAPO. Nível de Evidência II; Estudo Prospectivo.

Lumbar safety triangle: comparative study of coronal and coronal oblique planes in 3.0-T magnetic resonance imaging / Triângulo de segurança lombar: estudo comparativo dos planos coronal e coronal oblíquo em ressonância magnética 3.0-T

Abstract Objective: To compare the measurements of the lumbar safety triangle (Kambin's triangle) and the invasion of the dorsal root ganglion in the triangle in coronal and coronal oblique planes. Materials and Methods: A cross-sectional study, in which 210 3.0-T magnetic resonance images of L2-L5 were analyzed in coronal and coronal oblique planes. Exams with lumbar spine anomalies were excluded. Demographic (sex and age) and radiological variables were recorded by a single evaluator. Results: Most sample was female (57.1%), mean age 45.5 ± 13.3 (18-98 years). The measurements average, as well as the areas, gradually increased from L2 to L5. The dorsal root ganglion invaded the triangle in all images. The safety triangle average area was smaller in the coronal oblique plane than in the coronal plane. Of the seven dimensions of safety triangle obtained for each level of the lumbar spine, six were significantly smaller in the coronal oblique plane than in the coronal plane. The only dimension that showed no difference was the smallest ganglion dimension. Conclusion: The dimensions and areas investigated were smaller in coronal oblique plane, especially the area (difference > 1 mm). The analysis of the triangular zone in this plane becomes important in the preoperative assessment of minimally invasive procedures.

Resumo Objetivo: Comparar as medidas do triângulo de segurança lombar (triângulo de Kambin) e invasão do gânglio da raiz dorsal no triângulo nas incidências coronal e coronal oblíqua. Materiais e Métodos: Estudo transversal, em que foram analisadas 210 imagens de ressonância magnética 3.0-T de L2-L5 nos planos coronal e coronal oblíquo. Foram excluídos exames com anomalias da coluna lombar. Variáveis demográficas (sexo e idade) e radiológicas foram registradas por um único avaliador. Resultados: A maioria da amostra era do sexo feminino (57,1%), com idade média de 45,5 ± 13,3 (18-98 anos). A média das medidas, assim como as áreas, aumentaram gradativamente de L2 a L5. O gânglio da raiz dorsal invadiu o triângulo em todas as imagens. A área média do triângulo de segurança foi menor na incidência coronal oblíqua do que na incidência coronal. Das sete dimensões do triângulo de segurança obtidas para cada nível da coluna lombar, seis foram significativamente menores no plano coronal oblíquo do que no plano coronal. Única dimensão que não apresentou diferença foi a menor dimensão do gânglio. Conclusão: As dimensões e áreas investigadas foram menores na incidência coronal oblíqua, especialmente a área (diferença > 1 mm). A análise da zona triangular nesta incidência torna-se importante na avaliação pré-operatória de procedimentos minimamente invasivos.

Do Improved Trunk Mobility and Isometric Strength Correlate with Improved Pain and Disability after Multimodal Rehabilitation for Low Back Pain? / A melhora da mobilidade e da força isométrica do tronco se correlacionam com a melhora da dor e da incapacidade após a reabilitação multimodal para dor lombar?

Abstract Objective To determine the correlation between posttreatment trunk range of motion (ROM) and isometric strength (TIS) and pain and disability in patients who underwent multimodal rehabilitation for low back pain (LBP). Methods In this prospective cohort study, 122 patients undergoing multimodal rehabilitation for LBP were analyzed. The pre- and posttreatment numerical pain rating scale (NPRS) and the Oswestry disability index (ODI) scores, as well as trunk ROM and TIS were compared. The Pearson correlation was used to determine correlation between posttreatment clinical outcomes and ROM and TIS. Results At the end of treatment, the mean NPRS (p< 0.0001) and ODI (p< 0.0001) scores, mean trunk extension (p< 0.0001), and flexion (p< 0.0001) ROMs improved significantly. Similarly, posttreatment, the mean extension (p< 0.0001) and flexion (p< 0.0001) TISs improved significantly. There was a weak correlation between the NPRS score and ROM extension (r = -0.24, p= 0.006) and flexion strength (r = -0.28, p= 0.001), as well as between the ODI score and TIS extension (r = -0.30, p= 0.0007) and flexion (r = -0.28, p= 0.001). Conclusion Despite significant improvement in pain, disability, trunk ROM, and TIS with multimodal treatment, there was a weak correlation between posttreatment pain and function and trunk ROM and TIS. Improvement in pain and function with physical rehabilitation treatment for LBP is a complex phenomenon and needs further investigation.

Resumo Objetivo Determinar a correlação entre a amplitude de movimento (ADM) do tronco pós-tratamento e a força isométrica do tronco (FIT) e a dor e a incapacidade em pacientes submetidos à reabilitação multimodal para dor lombar (DL). Métodos Neste estudo de coorte prospectiva, 122 pacientes submetidos à reabilitação multimodal para DL foram analisados. Foram comparados os escores de escala numérica de dor pré- e pós-tratamento (END) e do índice de incapacidade Oswestry (Oswestry disability index - ODI), a ADM do tronco e a FIT. A correlação de Pearson foi utilizada para determinar a correlação entre desfechos clínicos e a ADM e a FIT pós-tratamento. Resultados Ao final do tratamento, as médias de ADM (p< 0,0001) e ODI (p< 0,0001), as ADMs médias de extensão (p< 0,0001) e a flexão (p< 0,0001) do tronco melhoraram significativamente. Da mesma forma, a FIT pós-tratamento, as FITs médias de extensão (p< 0,0001) e flexão (p< 0,0001) melhoraram significativamente. Houve uma correlação fraca entre o escore do END e a ADM de extensão (r = -0,24, p= 0,006) e força de flexão (r = -0,28, p= 0,001) pós-tratamento, assim como entre o escore de ODI e FIT de extensão (r = -0,30, p= 0,0007) e flexão (r = -0,28, p= 0,001) pós-tratamento. Conclusão Apesar da melhora significativa da dor, capacidade, ADM do tronco e FIT com tratamento multimodal, houve uma fraca correlação entre dor pós-tratamento e função e ADM e FIT de tronco. A melhora da dor e da função com o tratamento de reabilitação física para DL é um fenômeno complexo e precisa de uma investigação mais aprofundada.

Comparative Analysis Between Isolated Posterior and Anteroposterior Approaches for Severe Scoliosis Treatment / Análise comparativa entre as abordagens cirúrgicas por via posterior isolada e por via anteroposterior para tratamento de escoliose severa

Abstract Objective To comparatively analyze isolated posterior and double surgical approaches for the treatment of severe scoliosis. Methods We retrospectively analyzed medical records of 32 patients with scoliosis angular value > 70° submitted to surgical treatment in a tertiary hospital between 2009 and 2019. These patients were divided into two groups: PV group with 17 patients submitted to arthrodesis by isolated posterior route (PV) and APV group with 15 patients approached anteriorly and posteriorly (APV). In the PV group, there were 16 female patients and 1 male, with a mean age of 16.86 years old. In the APV group, there were 10 female patients and 5 males, with a mean age of 17.71 years old. Cobb angles were measured by a single spinal surgeon manually on panoramic radiographs, orthostasis before and after surgery. Weight, pre- and postoperative height, and duration of the procedure were also evaluated. Results In the PV group, preoperative and postoperative Cobb angles, verified in the main curve, were 96.06 ± 8.45° and 52.27 ± 15.18°, with an average correction rate of 0.54 ± 0.16, respectively. In the APV group, these values were 83.12 ± 11.60° for preoperative Cobb angle, and 48.53 ± 10.76° postoperatively, with correction rate of the main curve of 0.58 ± 0.11. Conclusion The two forms of surgical approach for the treatment of severe scoliosis were astowed as to the rate of correction of the deformity. Therefore, isolated posterior access has an advantage over the double approach, based on shorter surgical time, shorter hospital stay, and less risk of complications

Resumo Objetivo Analisar comparativamente as abordagens cirúrgicas por via posterior isolada e dupla abordagem para tratamento da escoliose severa. Métodos Analisou-se retrospectivamente prontuários de 32 pacientes com escoliose de valor angular > 70° submetidos a tratamento cirúrgico em hospital terciário entre 2009 e 2019. Dividiu-se estes pacientes em dois grupos: Grupo VP com 17 pacientes submetidos a artrodese por via posterior isolada (VP) e Grupo VAP com 15 pacientes abordados por via anterior e posterior (VAP). O Grupo VP apresentou 16 pacientes do sexo feminino e 1 do masculino, com idade média de 16,86 anos. No grupo VAP, 10 pacientes do sexo feminino e 5 do masculino, com idade média de 17,71 anos. Os ângulos de Cobb foram mensurados por único cirurgião de coluna, manualmente, em radiografias panorâmicas, em ortostase no pré- e pós-operatório. Foram avaliados também peso, altura pré- e pós-operatória e duração do procedimento. Resultados No Grupo VP, o ângulo de Cobb pré-operatório e pós-operatório, verificados na curva principal, foram respectivamente 96,06° ± 8,45° e 52,27 ± 15,18°, apresentando taxa média de correção de 0,54 ± 0,16. No grupo VAP, esses valores foram de 83,12° ± 11,60° para o ângulo de Cobb pré-operatório, 48,53 ± 10,76, pós-operatório, com a taxa de correção da curva principal de 0,58 ± 0,11. Conclusão As duas formas de abordagem cirúrgica para tratamento de escoliose severa se equiparam quanto à taxa de correção da deformidade. Portanto, o acesso posterior isolado apresenta vantagem em relação a dupla via, baseado no menor tempo cirúrgico, menor tempo de internação e menos risco de complicações

Morbilidad de las fracturas vertebrales osteoporóticas durante el aislamiento social en la pandemia COVID-19 / Osteoporotic vertebral fractures morbidity during social isolation on COVID-19 pandemic

Introducción: la pandemia por COVID-19 afectó negativamente los sistemas de salud. Las fracturas vertebrales osteoporóticas y el aislamiento social se relacionan con mayor morbimortalidad. Objetivos: caracterizar la morbilidad de las fracturas vertebrales osteoporóticas y evaluar una posible relación entre morbilidad y nivel de aislamiento social se-cundario al estado de pandemia. Material y métodos: estudio observacional, analítico y transversal. Resultados: se incluyeron en el estudio 45 adultos. La fractura fue mayorita-riamente lumbar con una evolución superior de 3 meses. El 35% presentaba seguimiento, el 48% había recibido tratamiento para osteoporosis y el 48% presentaba fracturas previas documentadas. El 46% refirió falta de accesibilidad al sistema. Se evaluó el aisla-miento social con la escala sociofamiliar de Gijón, que evidenció una situación buena en el 75% y un deterioro social intermedio/severo en el 24%. El Índice de Oswestry mostró una discapacidad mínima/moderada en el 66% y severa o mayor en el 33%. Se evaluó el dolor por la Escala análoga visual (VAS) y se obtuvo un VAS mayor de 5 en el 57%. Al comparar el grupo de situación sociofamiliar buena con el de deterioro social intermedio/severo se observó una diferencia en multipli-cidad de fracturas (p 0,030), hipovitaminosis D (p 0,045) y falta de accesibilidad (p 0,029). En discapacidad y dolor no hubo diferencias. Conclusión: el grupo con mayor aislamiento presentó una enfermedad más severa en términos de multiplicidad de fracturas e hipovitaminosis D; esto podría indicar una asociación entre aislamiento social secundario al estado de pandemia y morbilidad por las fracturas vertebrales. (AU)

Introduction: the COVID-19 pandemic had a negative impact on healthcare systems. Osteoporotic vertebral fractures and social isolation have a significant morbidity in our setting. Objectives: to characterize the morbidity of osteoporotic vertebral fractures and evaluate a potential relationship between morbidity and the level of social isolation secondary to the pandemic. Material and methods: observational, analytical and cross-sectional study. Results: forty-five adults were included. Fractures were mostly lumbar with a history of over 3 months. Thirty-five percent (35%) had been followed-up, 48% had been treated for osteoporosis and 48% had previous documented fractures. Forty-six percent (46%) reported lack of accessibility to healthcare. Social isolation was measured using Gijón ́s social-familial evaluation scale, which showed a good situation in 75% of cases and an intermediate/severe social deterioration in 24%. According to the Oswestry index, disability was minimal/moderate in 66% of cases and severe or worse in 33%. Pain was assessed using the Visual Analogue Scale (VAS), with a score greater than 5 recorded in 57% of patients. When comparing the group with a good social-familial situation vs. the group with intermediate/severe social deterioration, differences were found in multiplicity of fractures (p 0.030), hypovitaminosis D (p 0.045) and lack of accessibility (p 0.029). No differences were found in disability and pain. Conclusion: the group with higher levels of isolation exhibited more severe disease in terms of multiplicity of fractures and hypovitaminosis D, which might suggest an association between social isolation secondary to the pandemic and morbidity due to vertebral fractures.

Bilateral Variation of the Vertebral Artery: Report of a Case and its Clinical Implication / Variación Bilateral de la Arteria Vertebral; Reporte de un Caso y su Implicancia Clínica

SUMMARY: There are many reports on anatomical variations of the vertebral arteries, which may be related to origin, trajectory, caliber, and side. Bilateral variations are less frequent, however, and less common are bilateral variants that differ from each other. The aim of this work was to report the presence of a bilateral variation of the vertebral artery and its functional and clinical implications. Dissection of a female cadaver, fixed in 10 % buffered formaldehyde, which had not undergone any previous surgeries in the study area and had anatomical variations in both vertebral arteries. In each one, follow-up was done from its origin to its end, determining its trajectory, diameters, branching, and anatomical relations. A left vertebral artery was found, starting in the aortic arch and making a sinuous trajectory of 4 curvatures to enter the transverse foramen of C4. The right vertebral artery began as the first branch of the subclavian artery. Its initial trajectory was rectilinear, followed by a right concave curve, a 360° loop that included a second ascending curve, and ended straight before entering the transverse foramen of C6. The coexistence of bilateral variations in the vertebral arteries is possible. This atypical situation can potentially generate vascular and neurological pathologies, but with different symptoms and causes. Knowing these variations and deliberately searching for them will enable the specialist to make a suitable differential diagnosis.

Existen múltiples reportes sobre variaciones anatómicas de las arterias vertebrales, las que se pueden relacionar con origen, trayecto, calibre y lateralidad. Sin embargo, las variaciones bilaterales son menos frecuentes, y menos común es que las variantes bilaterales sean diferentes entre ellas. El objetivo de este trabajo fue reportar la presencia de una variación bilateral de la arteria vertebral y su implicancia funcional y clínica. Disección en un cadáver de sexo femenino, fijado en formaldehido tamponado al 10 %, el cual no presentaba intervenciones quirúrgicas previas en la región de estudio y que tenía variaciones anatómicas en ambas arterias vertebrales. En cada una se realizó seguimiento desde su origen hasta su terminación, pudiendo determinar su trayecto, diámetros, ramificaciones y relaciones anatómicas. Se encontró una arteria vertebral izquierda originada en el arco aórtico, que realizaba un trayecto sinuoso de 4 curvaturas e ingresaba al foramen transverso de C4. La arteria vertebral derecha se originaba como primera rama de la arteria subclavia. Su trayecto inicial era rectilíneo seguido por una curva de concavidad derecha, un loop (giro) de 360° que incluía una segunda curva ascendente y terminaba en dirección recta antes de ingresar al foramen transverso de C6. La coexistencia de variaciones bilaterales en las arterias vertebrales es posible. Esta situación atípica, potencialmente puede generar en la persona patologías neurológicas de origen vascular, pero con sintomatología y causas diferentes. Conocer estas variaciones y realizar una búsqueda intencionada de ellas permitirá el especialista realizar un adecuado diagnóstico diferencial.

Is Shoulder Imbalance a Useful Parameter in the Screening of Idiopathic Scoliosis? A Preliminary Study / O desequilíbrio do ombro é um parâmetro útil na triagem da escoliose idiopática? Um estudo preliminar

Abstract Objective The present study aims to analyze the use of shoulder imbalance as a parameter for scoliosis screening as well as its relationship with other parameters of physical examination. Methods This study assesses a smartphone application that analyzes several parameters of the physical examination in adolescent idiopathic scoliosis. Medical and non-medical examiners applied the screening tool in students in a public school and in a private sports club. After data collection, interobserver correlation was done to verify shoulder imbalance and to compare shoulder imbalance with Adam's bending test and with trunk rotation. Results Eighty-nine participants were examined, 18 of whom were women and 71 of whom were men. Two subjects were excluded from the analysis. The mean age of subjects from the public school was 11.30 years and, for those from the sports club, it was 11.92 years. The examiners had poor-to-slight interobserver concordance on shoulder asymmetry in the anterior and posterior view. No significant statistical correlation was found between shoulder asymmetry and positive Adam's forward bending test. Conclusion Our preliminary study shows that the shoulder asymmetry has a poor correlation with the Adam's forward bending test and measuring trunk rotation using a scoliometer. Therefore, the use of shoulder imbalance might not be useful for idiopathic scoliosis screening. Level of Evidence III; Diagnostic Study

Resumo Objetivo O objetivo deste estudo é analisar o uso da assimetria de ombros como parâmetro para a triagem de escoliose e sua relação a outros parâmetros do exame físico. Métodos Este estudo avalia um aplicativo para smartphone que analisa diversos parâmetros do exame físico de adolescentes com escoliose idiopática. Examinadores médicos e não médicos utilizaram o instrumento de triagem em alunos de uma escola pública e de um clube esportivo privado. Após a coleta de dados, a correlação interobservador foi determinada para verificar a assimetria de ombros e compará-la ao teste de inclinação de Adam e à medição da rotação do tronco. Resultados Oitenta e nove participantes foram examinados, sendo 18 do sexo feminino e 71 do sexo masculino. Dois indivíduos foram excluídos da análise. A média de idade dos participantes da escola pública foi de 11,30 anos e do clube esportivo, 11,92 anos. Os examinadores apresentaram concordância interobservador baixa a branda quanto à assimetria de ombros em incidência anterior e posterior. Não houve correlação estatística significativa entre a assimetria de ombros e o resultado positivo no teste de inclinação do tronco de Adam. Conclusão Nosso estudo preliminar mostra que a assimetria de ombros tem baixa correlação com o teste de inclinação de Adam e assim como com a medição de rotação do tronco com escoliômetro. Portanto, o uso da assimetria de ombros pode não ser útil na triagem da escoliose idiopática. Nível de Evidência III; Estudo Diagnóstico

Morphometric Study of Atlas Vertebra In Relation to Sulcus Arteriae Vertebralis

Background: Atlas(C1) is an atypical cervical vertebra shaped like a ring. Important structures like the vertebral artery, suboccipital plexus of veins and first cervical nerve pass through it. Knowledge of the variability of C1 is important for neurosurgeons, orthopaedicians, otorhynologists and other physicians who in everyday practice are in contact with disorders of the spine and their consequences. So, this study was undertaken to assess the various dimensions of the C1 in relation to the vertebral artery groove. Methods and materials: Fifty dried human atlas vertebrae were studied. Various measurements were done and statistically analysed. Results: Antero-posterior diameter (APD) of Foramen transversarium(FT) was measured as 7.73 ± 1.04mm on the right and 7.62 ± 0.90mm on left side. Transverse Diameter(TD) of FT was observed as 6.12 ± 0.97mm on the right side and 6.02 ± 0.97mm on the left side. Outer Distance of Vertebral Artery Groove(VAG) was measured as 26.22 ± 2.32mm and 25.84 ± 1.85mm on the right and left sides, respectively. Inner Distance of VAG was observed as 13.10 ± 1.66mm on right and 13.17 ± 1.57mm on the left side. APD of Superior Articular Facet(SAF) was 21.52 ± 2.36mm on right and 21.51 ± 2.07mm on left side.TD of SAF was 11.21 ± 1.47mm on right and 11.32 ± 1.53mm on left side. APD of Inferior Articular Facet(IAF) was observed as 17.54 ± 1.50mm on right and 17.70±1.60mm on left side. TD of IAF was observed as 14.99 ± 1.65mm on the right side and 14.94 ± 1.51mm on left side. Distance between lateral-most edge of both Foramen Transversaria was measured as 56.37 ± 4.11mm and distance between medial-most edge of both Foramen Transversaria was 44.78 ± 3.67mm. MaximumTD of Atlas was measured as 72.09± 5.59mm. Conclusion: The study will generate information that would be useful for geometric modelling of vertebrae and give necessary morphometric data on human atlas vertebra in Indian population.

A Morphometric Study of Typical and Atypical Lumbar Vertebrae in South Indian Population

Introduction:The lumbar vertebrae are affected in conditions such as congenital defects, degenerative diseases, accidents, and cancer metastasis. A thorough knowledge of the morphometry of typical and atypical lumbar vertebrae in adults of South Indian population is needed for lumbar spine surgeries. MaterialsandMethods: Adescriptive study was done on 200 dry lumbar vertebrae, of which 100 were typical and 100 were atypical lumbar vertebrae. The following dimensions of both typical and atypical lumbar vertebrae were measured with digital vernier calipers: anteroposterior and transverse diameters of the body; anterior and posterior body heights; anteroposterior and transverse diameters of vertebral foramen; height, breadth, and width of the laminae; length, height, and width of the pedicles; transverse processes and spinous process; distance between the two superior articular processes; and the distance between the two inferior articular processes. All the measurements were tabulated. The mean and standard deviation were calculated for each of the parameters and the results were statistically analyzed. Results: The anteroposterior and transverse diameters of the body, the height of the laminae on both sides, the length and height of the spinous process, and the distance between the superior articular facets were significantly longer in atypical lumbar vertebrae than that of typical lumbar vertebrae (P < 0.05). There was no significant difference in measurements between both sides. Conclusion: The dimensions of vertebral foramen, transverse processes, spinous processes, and distance between articular processes were different from the dimensions of previous studies. The morphometric data obtained will be useful for orthopedic procedures on the lumbar vertebrae in South Indian population

Fatores associados à incidência e à piora do problema de coluna durante a primeira onda da COVID-19 no Brasil / Factors associated with the incidence and worsening of back pain during the first wave of COVID-19 in Brazil

Resumo O artigo tem como objetivo estimar a incidência e o agravamento do problema de coluna (PC) durante a primeira onda da COVID-19 no Brasil, bem como investigar os fatores demográficos, socioeconômicos e as mudanças nas condições de vida associadas. Utilizou-se a ConVid - Pesquisa de Comportamentos, realizada entre abril e maio de 2020, como fonte de dados. Estimou-se o número e a distribuição dos entrevistados que desenvolveram PC e a dos que tiveram agravamento no problema preexistente, seus intervalos de 95% de confiança e o teste qui-quadrado de Pearson. Estimou-se também a razão de chance de desenvolver PC ou ter piora de problema preexistente por meio de modelos de regressão logística múltipla. O PC preexistente foi reportado por 33,9% (IC95% 32,5-35,3) dos entrevistados e mais da metade (54,4%; IC95% 51,9-56,9) teve piora do quadro. A incidência cumulativa de PC na primeira onda da pandemia foi de 40,9% (IC95% 39,2-42,7). Ser mulher, o aumento percebido do trabalho doméstico e o sentimento frequente de tristeza ou depressão foram associados a ambos os desfechos. Os fatores socioeconômicos não foram associados a nenhum dos desfechos. A alta incidência e agravamento do PC durante a primeira onda revelam a necessidade de estudos em períodos mais recentes, dada a longa duração da pandemia.

Abstract The article aims to estimate the incidence and worsening of back pain (BP) during the first wave of COVID-19 in Brazil, as well as to investigate demographic, socioeconomic factors and associated changes in living conditions. ConVid - Behavior Research, applied between April and May 2020, was used as data source. The number and distribution of respondents who developed BP and those who had a worsening of the preexisting problem, their 95% confidence intervals and Pearson's Chi-square test were estimated. The odds ratio of developing BP or worsening a preexisting problem was also estimated using multiple logistic regression models. Pre-existing BP was reported by 33.9% (95%CI 32.5-35.3) of respondents and more than half (54.4%; 95%CI 51.9-56.9) had worsened. The cumulative incidence of BP in the first wave of the pandemic was 40.9% (95%CI 39.2-42.7). Being a woman, the perceived increase in housework and the frequent feeling of sadness or depression were associated with both outcomes. Socioeconomic factors were not associated with any of outcome. The high incidence and worsening of BP during the first wave reveal the need for studies in more recent periods, given the long duration of the pandemic.

Study of Incidence of Ponticulus Posterior In Dry Human Atlas Vertebra and Its Clinical Significance

Background: Atlas is the first cervical vertebra. The vertebral artery lies in the groove on posterior arch of the atlas. The vertebral artery groove may sometimes get converted into a foramen. This is commonly known as ponticulus posterior (ponticulus posticus) or arcuate foramen of the atlas. These foramina may be complete or incomplete. This can lead to compression of the vertebral artery and produce symptoms like headache, syncope, altered consciousness etc. It can also complicate manipulations of the cervical spine by reducing the blood flow during extreme rotations of head and neck. It is also associated with vertebrobasilar artery stroke So, neurosurgeons or orthopaedic surgeons who operate in this area should have a detailed knowledge of variations of groove for the vertebral artery. Materials and Methods: The present study was conducted on 50 dried and fully ossified adult human atlas of unknown age and sex collected from the department of Anatomy, Government Medical college, Nagpur. Each atlas vertebra was carefully observed for the presence or absence of complete or incomplete ponticuli on superior surface of posterior arch of atlas. Results: Out of the 50 vertebra studied 7(14%) showed the presence of Ponticuli. Ponticuli were incomplete in all 7 atlas vertebras. Complete ring was not observed in any of the atlas vertebra .Out of the 7 ponticuli 6(12%) were found to be unilateral and in only 1 (2%) case it was found to be bilateral. Out of the 6 ponticuli 4(8%) were noticed on the Left side and 2(4%) were present on the right side. Conclusion: Presence of incomplete ponticulus posterior might cause cervical pain and even cerebrovascular disorders due to pressure on third part of vertebral artery present in the vertebral artery groove. This anatomical knowledge is important for neurosurgeons, orthopaedic surgeons, radiologists and clinicians while dealing with this region.

Epidemiology of Orthopaedic Fractures and Other Traumatic Injuries among Patients Admitted in a Tertiary Care Hospital: An Observational Study

Background: Orthopaedic fractures and traumatic injuries are a growing concern for healthcare systems worldwide. Road Traffic Accidents (RTA) are among the top five causes of illness and mortality in South East Asian nations. Trauma caused by other factors, such as accidents at work or home, falls, and assaults, significantly contribute to overall mortality and morbidity. This study aims to investigate the occurrence of traumatic injuries with associated factors and find significant orthopaedic fracture patterns. Material & Methods: This study was a retrospective observational study that was conducted on 208 patients who were admitted to the department of orthopaedics at Dhaka Medical College and Hospital during the study period between April 2004 and June 2007 those who fulfilled the selection criteria were enrolled in this study. All data were processed and analyzed with the help of SPSS (Statistical Package for Social Sciences) version 25. The data were expressed as frequency and percentage in tables and graphs. Results: During the study period total number of study patients were 208 where 131 (62.98%) patients were male, and 77(37.02%) were female. The majority, 53 (25.48%) of the patients, were aged between 31-40 years. RTAs were responsible for 92 cases (44.23%) of all traumatic orthopaedic injuries and followed by falls accounting for 42 patients (20.19%) of injuries. Majority 46(22.12%) of the patients had fractures in femur, second majority 38(18.27%) patients had fracture in tibia/fibula. The most common fracture site being the lower limbs (58 cases, 27.88 %). Conclusion: The study concluded that the incidence of traumatic orthopaedic injuries was higher in young male adults compared to all other study groups. The three most frequent causes of injuries were falls, RTAs, and assaults were the most prevalent form of injury. The most frequently damaged bones are the femur and tibia/fibula.

The Relative Lymphocyte Count is Lower when the Etiological Agent in Pott Disease is Successfully Isolated / O número relativo de linfócitos é menor quando o agente etiológico da doença de Pott é isolado com sucesso

Abstract Objective To describe the clinico-epidemiological, laboratory, and radiological characteristics of tuberculous spondylodiscitis in the Brazilian population, and to assess whether there are differences between patients in whom the etiological agent in Pott disease was isolated or not. Methods Patients diagnosed with tuberculosis (TB) of the spine (Pott disease) underwent follow-up between 2009 and 2019 at a quaternary hospital and were divided into 2 groups: successful isolation (SI) of the etiological agent (through bacilloscopy, culture, or positive molecular rapid test) and unsuccessful isolation (UI) of the etiological agent. Results From a total of 26 patients diagnosed with TB of the spine, 21 (80.7%) were male, with a mean age of 40 ± 22.5 years. The average lymphocyte counts were higher in the UI group (25.35 ± 13.08; p= 0.025) compared to the SI group (14.18 ± 7.48). Moreover, the monocyte/lymphocyte ratio was lower in the UI group (0.39 ± 0.22; p= 0.009) than in the SI group (0.89 ± 0.65). Relative lymphocyte counts higher than or equal to 16.7 had a sensitivity of 76.9% and specificity of 62.5% in the UI group. Values higher than or equal to 0.58 for the monocyte/lymphocyte ratio showed a sensitivity of 84.6% and specificity of 75.0% in the UI group. Conclusion No differences were observed regarding the clinico-epidemiological and radiological characteristics of the two experimental groups. However, the UI group had higher lymphocyte counts and a lower monocyte/lymphocyte ratio.

Resumo Objetivo Descrever as características clínico-epidemiológicas, laboratoriais e radiológicas da espondilodiscite tuberculosa na população brasileira e avaliar se há diferenças entre pacientes em que o agente etiológico da doença de Pott foi isolado ou não. Métodos Os pacientes diagnosticados com tuberculose (TB) da coluna (doença de Pott) foram acompanhados em um hospital quaternário entre 2009 e 2019 e divididos em 2 grupos: isolamento positivo (IP) do agente etiológico (por baciloscopia, cultura ou teste rápido molecular positivo) e isolamento negativo (IN) do agente etiológico. Resultados De um total de 26 pacientes com diagnóstico de TB da coluna, 21 (80,7%) eram do sexo masculino, e a média de idade era de 40 ± 22,5 anos. As contagens médias de linfócitos foram maiores no grupo IN (25,35 ± 13,08; p= 0,025) do que no grupo IP (14,18 ± 7,48). Além disso, a relação monócito/linfócito foi menor no grupo IN (0,39 ± 0,22; p= 0,009) do que no grupo IP (0,89 ± 0,65). O número relativo de linfócitos maior ou igual a 16,7 teve sensibilidade de 76,9% e especificidade de 62,5% no grupo IN. A razão monócito/linfócito maior ou igual a 0,58 teve sensibilidade de 84,6% e especificidade de 75,0% no grupo IN. Conclusão Não observamos diferenças em relação às características clínico-epidemiológicas e radiológicas entre os dois grupos experimentais. No entanto, o grupo IN apresentou maior número de linfócitos e menor razão monócito/linfócito.

Sagittal Alignment Concepts and Spinopelvic Parameters / Conceitos de alinhamento sagital e parâmetros espinopélvicos

Abstract Spinal surgery continues to expand its horizons to care for disabled patients presenting pain and deformities. Over the past decade, our knowledge of spinal alignment, from the skull to the pelvis, has increased considerably. Such knowledge must expand to reach general orthopedists and improve the care required for so many people. Global spinal alignment is a critical concept in understanding the impact of pathological conditions (degenerative diseases, traumas, deformities) and their treatment, including spinal instrumentation and arthrodesis. Therefore, the treatment of any spinal disease must include the knowledge of the complexity of the spinopelvic alignment. At first, all parameters seem like pure mathematics, hardly applicable to the everyday life of the inattentive reader. However, it gradually becomes clear that, like everything else in orthopedics, biomechanics is an essential part of the knowledge of the musculoskeletal system, revealing the logic behind the physiology of movements. The knowledge of the sagittal alignment concepts and spinopelvic parameteres provide a better comprehension of the axial and appendicular skeletons, increasing the understanding of the physiological and adaptive spinal processes in the face of the degenerative process that increases throughout life.

Resumo A cirurgia da coluna continua a expandir seus horizontes para cuidar dos pacientes incapacitados com dor e deformidades. Desde a última década, nosso conhecimento sobre o alinhamento espinal, do crânio à pelve, aumentou consideravelmente. Portanto, faz-se necessária a expansão de tal conhecimento para o ortopedista geral, para que possamos proporcionar melhores cuidados para essa população. O alinhamento espinal global é um conceito crítico no entendimento do impacto ocasionado pela condição patológica (doença degenerativa, trauma, deformidade) e mesmo do seu tratamento, como na instrumentação e artrodese da coluna. O tratamento de qualquer doença na coluna deve incluir o entendimento da complexidade do alinhamento espinopélvico. A princípio, todos os parâmetros parecem puramente matemáticos e pouco aplicáveis à realidade do leitor mais desatento. Mas, aos poucos, fica claro que, como tudo em ortopedia, a biomecânica faz parte essencial do conhecimento do sistema musculoesquelético, tornando mais claras as lógicas da fisiologia do movimento. O conhecimento dos conceitos de alinhamento sagital e dos parâmetros espinopélvicos proporcionam uma melhor compreensão dos esqueletos axial e apendicular, além de um melhor entendimento dos processos fisiológicos e adaptativos da coluna frente ao processo degenerativo crescente que ocorre ao longo da vida.

Axial Axis Metastasis / Metástase do eixo axial

Abstract Axial axis metastasis remains a challenge for surgical as well as other treatment modalities, like chemotherapy, immunotherapy, and radiotherapy. It is unequivocal that surgery provides pain improvements and preservation of neurological status, but this condition remains when associated with radiotherapy and other treatment modalities. In this review, we emphasize the current forms of surgical treatment in the different regions of the spine and pelvis. The evident possibility of percutaneous treatments is related to early or late cases, and in cases in which there are greater risks and instability to conventional surgeries associated with radiotherapy and have been shown to be the appropriate option for local control of metastatic disease.

Resumo As metástases no eixo axial permanecem um desafio para o tratamento cirúrgico bem como para outras modalidades, como quimioterapia, imunoterapia e radioterapia. É inequívoco que a cirurgia proporciona melhorias na dor e na preservação do status neurológico; porém, há permanência desta condição quando associada à radioterapia e a outras modalidades de tratamento. Nesta revisão damos ênfase às formas de tratamento cirúrgico atuais nas diferentes regiões da coluna vertebral e pelve. A evidente possibilidade de tratamentos percutâneos está relacionada a casos iniciais ou tardios, bem como a casos em que há maiores riscos e instabilidade às cirurgias convencionais associadas à radioterapia, e tem se mostrado a opção adequada para o controle local da doença metastática.

Comparison Between Surgical and Conservative Treatment for AOSpine Type A3 and A4 Thoracolumbar Fractures without Neurological Deficit: Prospective Observational Cohort Study / Comparação entre tratamento cirúrgico e conservador para fraturas toracolombares AOSpine tipo A3 e A4 sem déficit neurológico: Estudo de coorte prospectivo observacional

Abstract Objective To compare the clinical results between conservative (CS) and surgical treatment (CXS) of A3 and A4 fractures without neurological deficit. Methods Prospective observational study of patients with thoracolumbar fractures type A3 and A4. These patients were separated between the surgical and conservative groups, and evaluated sequentially through the numeric rating scale (NRS), Roland-Morris disability questionnaire (RMDQ), EuroQol-5D (EQ-5D) quality of life questionnaire, and Denis work scale (DWS) up to 2.5 years of follow-up. Results Both groups showed significant improvement, with no statistical difference in pain questionnaires (NRS: CXS 2.4 ± 2.6; CS 3.5 ± 2.6; p> 0.05), functionality (RMDQ: CS 7 ± 6.4; CXS 5.5 ± 5.2; p> 0.05), quality of life (EQ-5D), and return to work (DWS). Conclusion Both treatments are viable options with equivalent clinical results. There is a tendency toward better results in the surgical treatment of A4 fractures.

Resumo Objetivo Comparar os resultados clínicos entre os tratamentos conservador (CS) e cirúrgico (CXS) das fraturas A3 e A4 sem déficit neurológico. Métodos Estudo prospectivo observacional de paciente com fraturas toracolombares tipo A3 e A4. Esses pacientes foram separados entre os grupos cirúrgico e conservador e avaliados sequencialmente através da escala numérica de dor (NRS), do questionário de incapacidade de Roland-Morris (RMDQ), do EuroQol-5D (EQ-5D) e da escala de trabalho de Denis (DWS) até 2,5 anos de acompanhamento. Resultados Ambos os grupos apresentaram melhora significante, sem diferença estatística nos questionários de dor (NRS: CXS 2,4 ± 2,6; CS 3,5 ± 2,6; p> 0,05), funcionalidade (RMDQ: CS 7 ± 6,4; CXS 5,5 ± 5,2; p> 0,05), qualidade de vida (EQ-5D) e retorno ao trabalho (DWS). Conclusão Ambos os tratamentos são opções viáveis e com resultados clínicos equivalentes. Há uma tendência a melhores resultados no tratamento cirúrgico das fraturas A4.

Impacts of the Delayed Surgical Correction of Adolescent Idiopathic Scoliosis and its Repercussions for the Brazilian Unified Health System: Systematic Review Protocol / Impactos da espera para correção cirúrgica da escoliose idiopática do adolescente e suas repercussões para o Sistema Único de Saúde: Protocolo de revisão sistemática

Abstract Surgical correction is an effective treatment for adolescent idiopathic scoliosis (AIS) with deformities over 45°. In the Brazilian Unified Health System (SUS, Sistema Único de Saúde), if the surgical procedure is indicated, the patients are placed on a waiting list and wait until the treatment can be performed. An extended waiting period can be harmful due to worsening symptoms and increased treatment costs. Additionally, it has negative effects on the mental health and quality of life of these patients. This paper is a systematic review protocol to answer the following question: "What is the impact of the delayed surgical correction of AIS considering costs and quality of life?" Collecting health status information is the first step to improve high complex public health actions. Future publications from this protocol may serve as a subsidy to point out potential priority criteria to enhance the global health of AIS patients and the management of Brazilian public health financial resources.

Resumo A correção cirúrgica é uma opção efetiva de tratamento para casos de Escoliose Idiopática do Adolescente (EIA) com curvas acima de 45°. No âmbito do Sistema Único de Saúde (SUS), os pacientes avaliados nos centros de referência e com indicação cirúrgica são cadastrados em fila de espera até que o tratamento definitivo possa ser realizado. Um período de espera extenso pode ser prejudicial, do ponto de vista de piora dos sintomas e de aumento do custo de tratamento, além de gerar efeitos negativos na saúde mental e na qualidade de vida do paciente. O presente artigo trata-se do protocolo de uma revisão sistemática que buscará responder o questionamento: "Qual o impacto do tempo de espera para correção cirúrgica da EIA do ponto de vista de custo e qualidade de vida?." O aperfeiçoamento das ações de saúde pública, na esfera da alta complexidade, inicia-se com o levantamento de informações sobre a situação de saúde de determinada condição. Diante disso, as futuras publicações provenientes deste protocolo poderão servir como subsídio para apontar possíveis critérios de prioridade, com o intuito de promover melhoria tanto no âmbito da saúde global de portadores de EIA, quanto na gestão financeira da saúde pública brasileira.

Spinal Cord Alignment in Patients with Thoracolumbar Burst Fracture / Alinhamento espinopélvico em pacientes com fratura toracolombar explosão

Abstract Objective To evaluate the spinopelvic alignment in patients with thoracolumbar burst fracture (TBF) without neurological deficit treated nonsurgically and surgically in a tertiary reference trauma hospital. Method Retrospective cross-sectional study of patients with single level, type A3 and A4 AOSpine TBF only of the thoracolumbar region. Analysis of clinical data, low back pain (visual analogue scale [VAS]), Denis Pain Scale, quality of life (SF-36), sagittal (TC, TLC, LL, SVA) and spinopelvic (IP, PV, SI, PI-LL) radiographic parameters of patients treated surgically and nonsurgically. Results A total of 50 individuals with an average age of 50 years old with a mean follow-up of 109 months (minimum of 19 and maximum of 306 months) were evaluated. There was a significant difference between treatments for the Denis Work Scale (p= 0.046) in favor of nonsurgical treatment. There was no significant difference between the treatments for lower back pain VAS and Denis Pain Scale (p= 0.468 and p= 0.623). There was no significant difference between treatments in any of the domains evaluated with the SF-36 (p> 0.05). Radiographic parameters were not different between the analyzed groups; however, all radiographic parameters showed significant difference between the population considered asymptomatic, except for pelvic incidence (p< 0.005). Conclusions The spinopelvic alignment was normal in patients with TBF without neurological deficit treated nonsurgically and surgically after a minimum follow-up of 19 months. However, they presented a higher mean pelvic version and discrepancy between lumbar lordosis and pelvic incidence when compared with the reference values of the Brazilian population.

Resumo Objetivo Avaliar o alinhamento espinopélvico em pacientes com fratura toracolombar do tipo explosão (FTE) sem déficit neurológico tratados de forma não operatória e operatória em um hospital terciário de referência em trauma. Método Estudo transversal retrospectivo de pacientes com FTE apenas da região toracolombar, de nível único, do tipo A3 e A4 AOSpine. Análise de dados clínicos, dor lombar (escala visual analógica [EVA]), Escala de Denis, qualidade de vida (SF-36), parâmetros radiográficos sagitais (cifose torácica [CT], cifose toracolombar [CTL], lordose lombar [LL] e eixo vertical sagital [EVS]) e espinopélvicos (incidência pélvica [IP], versão pélvica [VP], inclinação sacral [IS] e a discrepância entre incidência pélvica e lordose lombar [IP-LL]) de pacientes tratados de forma operatória e não operatória. Resultados O presente estudo avaliou um total de 50 indivíduos com uma média de 50 anos de idade com acompanhamento médio de 109 meses (mínimo de 19 e máximo de 306 meses). Houve diferença significativa entre os tratamentos para Denis trabalho (p= 0,046) a favor do tratamento não operatório. Não houve diferença significativa entre os tratamentos para EVA dor lombar e Denis dor (p= 0,468 e p= 0,623). Não houve diferença significante entre os tratamentos em nenhum dos domínios avaliados do SF-36 (p> 0,05). Parâmetros radiográficos não se mostraram diferentes entre os grupos analisados; contudo, todos os parâmetros radiográficos mostraram diferença significante entre a população considerada assintomática, com exceção da incidência pélvica (p< 0,005). Conclusões O alinhamento espinopélvico foi normal em pacientes com FTE sem déficit neurológico tratados de forma não operatória e operatória, após acompanhamento mínimo de 19 meses. Entretanto, estes pacientes apresentaram maior média de versão pélvica e de discrepância entre lordose lombar e incidência pélvica quando comparados com os valores de referência da população brasileira.

Experiencia en patología cervical alta en el Hospital Guillermo Almenara Irigoyen 2016 - 2021

Introducción : El complejo C0-C1-C2 es responsable de la transición de la carga axial, con función biomecánica única, siendo afectada por múltiples patologías, que por lo general la literatura no las considera como un solo ítem, sino que lo desarrolla según su etiología, pero en nuestro estudio se ha considerado en 5 grupos: traumática, congénita, inflamatoria reumática, neoplásica y degenerativa. Objetivo : Determinar las características epidemiológicas, clínicas y del tratamiento en la patología cervical alta. Materiales y métodos : Se incluyeron a todos los pacientes con diagnóstico clínico radiológico de alguna patología cervical alta que hayan sido sometidos a tratamiento quirúrgico entre 2016 y 2021 en el Hospital Almenara. Se usó el test "t" de student y de chi cuadrado. Se dividió a los pacientes en alguno de los 5 grupos antes mencionados. Resultados : Se consideraron 31 pacientes, con una edad media de 51.16 años. La patología cervical alta más frecuente fue la traumática con el 35.48%. El déficit motor se presentó en el 51.61% y el déficit sensitivo se presentó en el 54.84%. La cirugía más frecuente fue la fijación cervical alta con el 43.89%. La tasa de complicaciones fue del 16.13% con una mortalidad del 0%. Conclusiones : La patología cervical alta es rara, siendo la del tipo traumática la más frecuente, pero un manejo oportuno y adecuado permite un mejor pronóstico funcional del paciente.

Introduction : The C0-C1-C2 complex is responsible of axial load transition, and its biomechanical function is unique, it is affected by multiple pathological conditions; and generally speaking, the literature does not consider these conditions as a single item, it describes them according to etiology. For our study we considered five groups: trauma-related, congenital, rheumatic-inflammatory, neoplastic, and degenerative. Objective : To determine epidemiological, clinical, and therapy-related characteristics in upper cervical pathological conditions. Materials and methods : All patients with a clinical-radiological diagnosis of any upper cervical pathological condition that had undergone surgery between 2016 and 2021 in Guillermo Almenara Hospital were included. Student's t test and chi square methods were used. patients were divided into one of the five aforementioned groups. Results : Thirty-one patients were included in the study; their mean age was 51.16 years. The most frequent upper cervical pathological condition was trauma-related, with 35.48%. Motor deficit occurred in 51.61% of all patients, and sensitive deficit occurred in 54.84%. The most frequently surgical procedure performed was upper cervical fixation, in 43.89% of all patients. Complication rate was 16.13%, and mortality was 0%. Conclusions : Upper cervical pathological conditions are rare, trauma-related conditions are most frequent, but timely and adequate management allow us to achieve better functional prognosis for these patients.
