ABSTRACT

Abstract Objective To evaluate and correlate the pelvic parameters, the sagittal balance (SB), and the functional outcome of the patients submitted to surgical treatment for Scheuermann hyperkyphosis (SK). Methods Patients submitted to surgery between January 2005 and December 2016 were included. The following radiographic measurements were obtained: thoracic kyphosis (TK); lumbar lordosis (LL); SB; pelvic incidence (PI); pelvic tilt (PT); and sacral slope (SS). Complications during the follow-up period were recorded. Results A total of 19 patients were included (16 males): the mean preoperative kyphosis was of 83°, and the postoperative kyphosis was of 57°. The mean preoperative lumbar lordosis was of 66°, with a postoperative spontaneous correction of 47°. Regarding the preoperative pelvic parameters, the average PI, PT and SS were of 48°,10° and 39° respectively. In the postoperative period, these values were of 50°, 16° and 35° respectively. The preoperative SB was neutral, and it was maintained after the surgical correction. Concerning complications during the follow-up period, three junctional kyphosis were observed-two requiring revision surgery, one nonunion, and one dehiscence of the surgical wound. Regarding the functional results, the average score on the Scoliosis Research Society-22 (SRS-22) patient questionnaire was of 4.04, and we verified that the SB obtained in the postoperative period had no influence on the functional outcome (p = 0.125) nor on the postoperative LL (p = 0.851). Conclusion We verified a spontaneous improvement in the lumbar hyperlordosis at levels not included in the fusion after correction of the TK. Although the postoperative functional results were globally high, we did not find any statistically significant relationship with TK nor LLs. high PI is associated with a greater rate of complications regarding the proximal junctional kyphosis (PJK), and these pelvic parameters should be considered at the time of the SK surgical treatment.


Resumo Objetivo Avaliar e correlacionar os parâmetros pélvicos, o equilíbrio sagital (SB), e o resultado funcional dos pacientes submetidos ao tratamento cirúrgico da hipercifose de Scheuermann (SK). Métodos Foram incluídos pacientes submetidos à cirurgia entre janeiro de 2005 e dezembro de 2016. Foram obtidas as seguintes medidas radiográficas: cifose torácica (TK); lordose lombar (LL); SB; incidência pélvica (PI); inclinação pélvica (PT); e inclinação sacral (SS). Complicações foram registradas durante o período de seguimento. Resultados Foram incluídos 19 pacientes (16 homens): a cifose pré-operatória média foi de 83°, e, após a cirurgia, de 57°. A LL média pré-operatória foi de 66°, com uma correção espontânea pós-operatória de 47°. Quanto aos parâmetros pélvicos préoperatórios, as médias de PI, PT e SS foram de 48°, 10° e 39°, respectivamente. No pósoperatório, esses valores foram de 50°, 16° e 35°, respectivamente. O SB pré-operatório foi neutro e mantido após correção cirúrgica. Quanto às complicações durante o período de seguimento, foram observadas três cifoses juncionais - duas necessitando de cirurgia de revisão, uma má consolidação, e uma deiscência de sutura. Em relação aos resultados funcionais, a pontuação média no questionário de 22 itens da Scoliosis Research Society (SRS-22) foi de 4,04, e verificou-se que o SB no pós-operatório não teve influência no desfecho funcional (p = 0,125), nem na LL pós-operatória (p = 0,851). Conclusão Verificamos uma melhora espontânea da hiperlordose lombar em níveis não incluídos na fusão após a correção da TK. Embora os resultados funcionais pósoperatórios tenham sido globalmente elevados, não encontramos nenhuma relação estatisticamente significativa com a TK nem com a LL. A PI elevada está associada a maior complicação da cifose juncional proximal (PJK), e esses parâmetros pélvicos devem ser considerados no momento do tratamento cirúrgico da cifose de Scheuermann.

ABSTRACT

ABSTRACT Objective: To evaluate the importance of radiography in the orthostatic position in the initial assessment of patients with thoracolumbar transition fractures and whether this image changes the surgical indication. Methods: Medical records and imaging tests of patients treated for thoracolumbar transition fractures from June 2018 to June 2019 were evaluated. Trauma patients between 18 and 60 years of age with fractures of T10 to L3 who had been indicated for conservative treatment were included. Cases of fractures considered unstable were excluded. Radiographs were taken with the patient in the supine position (supine X-ray), computed tomography (CT), and orthostatic radiography (orthostatic X-ray). Segmental kyphosis and degree of wedging were evaluated. The measurements were compared using the Wilcoxon test. The McNemar test was used to assess changes in conduct according to the criteria for surgical indication (kyphosis ≥ 25 ° and wedging ≥ 50%). Results: Fifty patients were evaluated, nine of whom (18%) were indicated for a change of conduct according to the orthostatic examinations and were submitted to surgical treatment. Vertebral kyphosis increased by 40.6% (p <0.001). The wedging increased by 25.62% (p <0.0001). Conclusion: Eighteen percent of the total number of patients who did not present instability criteria in radiographs in the supine position satisfied at least one of these criteria when the orthostatic X-ray was performed. Level of evidence 3B; Retrospective case series study.

ABSTRACT

BACKGROUND@#Finding an optimal treatment strategy for adolescent idiopathic scoliosis (AIS) patients remains challenging because of its intrinsic complexity. For mild to moderate scoliosis patients with lower skeletal growth potential (Risser 3-5), most clinicians agree with observation treatment; however, the curve progression that occurs during puberty, the adolescent period, and even in adulthood, remains a challenging issue for clinicians. The aim of the study is to investigate the efficacy of Schroth exercise in AIS patients with lower skeletal growth potential (Risser 3-5) and moderate scoliosis (Cobb angle 20°-40°).@*METHODS@#From 2015 to 2017, data of 64 patients diagnosed with AIS in Peking University Third Hospital were reviewed. Forty-three patients underwent Schroth exercise were classified as Schroth group, and 21 patients underwent observation were classified as observation group. Outcomes were measured by health-related quality of life (HRQOL) and radiographic parameters. HRQOL was assessed using the visual analog scale (VAS) scores for back, Scoliosis Research Society-22 (SRS-22) patient questionnaire. Radiographic spinopelvic parameters were obtained from anteroposterior and lateral X-rays. The pre-treatment and post-treatment HRQOL and radiographic parameters were tested to validate Schroth exercise efficacy. The inter-rater reliability of the radiographic parameters was tested using the interclass correlation coefficient (ICC). The paired t test was used to examine HRQOL and radiographic parameters. Clinical relevance between C2-C7 sagittal vertical axis (SVA) and thoracic kyphosis was analyzed using Spearman correlation.@*RESULTS@#In Schroth group, VAS back score, SRS-22 pain, and SRS-22 self-image domain were significantly improved from pre-treatment 3.0 ± 0.8, 3.6 ± 0.5, and 3.5 ± 0.7 to post-treatment 1.6 ± 0.6 (t = 5.578, P = 0.013), 4.0 ± 0.3 (t = -3.918, P = 0.001), and 3.7 ± 0.4 (t = -6.468, P < 0.001), respectively. No significant improvements of SRS-22 function domain (t = -2.825, P = 0.088) and mental health domain (t = -3.174, P = 0.061) were observed. The mean Cobb angle decreased from 28.9 ± 5.5° to 26.3 ± 5.2° at the final follow-up, despite no statistical significance was observed (t = 1.853, P = 0.102). The mean C2-C7 SVA value decreased from 21.7 ± 8.4 mm to 17.0 ± 8.0 mm (t = -1.224 P = 0.049) and mean T1 tilt decreased from 4.9 ± 4.2 ° to 3.5 ± 3.1° (t = 2.913, P = 0.011). No significant improvement of radiographic parameters and HRQOL were observed in observation group.@*CONCLUSIONS@#For AIS patients with a Risser 3-5 and a Cobb angle 20°-40°, Schroth exercises improved HRQOL and halted curve progression during the follow-up period. Both cervical spine alignment and shoulder balance were also significantly improved after Schroth exercises. We recommend Schroth exercises for patients with AIS.

ABSTRACT

OBJECTIVE@#To explore the clinical effects of posterior short-segment pedicle screw internal fixation combined with vertebroplasty for the treatment of Kümmell disease with kyphosis.@*METHODS@#Twenty-four patients with Kümmell disease complicated with kyphosis treated by posterior short-segment pedicle screw internal fixation combined with vertebroplasty from January 2016 to December 2018 were retrospectively analyzed, including 6 males and 18 females, aged 63 to 85 (73.1±6.5) years old. The clinical effect was evaluate by visual analogue scale (VAS), Oswestry Disability Index (ODI), the anterior height of injured vertebral body, and the sagittal Cobb angle of the affected segment beforeoperation, at 3 days and final follow up after operation. And the surgical complications were observed.@*RESULTS@#All 24 patients were followed up from 12 to 24 months with an average of (15.5±3.2) months. The VAS score was decreased from 5.21±1.06 preoperatively to 2.38±0.58 at 3 days postoperatively and 1.71±0.75 at final follow-up;ODI was decreased from (50.4±13.5)% preoperatively to (20.9±8.0)% at 3 days postoperatively and (16.7±9.6)% at final follow-up;the anterior height of injured vertebral body was restored from (8.0±4.2) mm before surgery to (18.1±5.0) mm at 3 days after surgery and (16.8±5.1) mm at final follow up;the sagittal Cobb angle of affected segment was decreased from (19.5±6.3)° preoperatively to (7.6±2.1)° at 3 days after surgery and(8.4±1.7)° at final follow-up. VAS, ODI, anterior height of injured vertebral body, and sagittal Cobb angle of affected segment were significantly improved at 3 days after operation and at final follow-up (@*CONCLUSION@#Posterior short-segment pedicle screw internal fixation combined with vertebroplasty for the treatment of Kümmell disease with kyphosis has relatively small surgical trauma, excellent clinical results, good vertebral height recovery, satisfactory correction of kyphotic angle, and fewer complications, etc. It is a safe and effective surgical method to treat Kümmell disease with kyphosis.

ABSTRACT

BACKGROUND@#Andersson lesions (ALs) are not uncommon in ankylosing spondylitis (AS). Plain radiography (PR) is widely used for the diagnosis of ALs. However, in our practice, there were some ALs in AS patients that could not be detected on plain radiographs. This study aimed to propose the concept of occult ALs and evaluate the prevalence and radiographic characteristics of the occult ALs in AS patients.@*METHODS@#A total of 496 consecutive AS patients were admitted in the Affiliated Drum Tower Hospital, Medical School of Nanjing University between April 2003 and November 2019 and they were retrospectively reviewed. The AS patients with ALs who met the following criteria were included for the investigation of occult ALs: (1) with pre-operative plain radiographs of the whole-spine and (2) availability of pre-operative computed tomography (CT) and/or magnetic resonance imaging (MRI) of the whole-spine. The occult ALs were defined as the ALs which were undetectable on plain radiographs but could be detected by CT and/or MRI. The extensive ALs involved the whole discovertebral junction or manifested as destructive lesions throughout the vertebral body. Independent-samples t test was used to compare the age between the patients with only occult ALs and those with only detectable ALs. Chi-square or Fisher exact test was applied to compare the types, distribution, and radiographic characteristics between detectable and occult ALs as appropriate.@*RESULTS@#Ninety-two AS patients with a mean age of 44.4 ± 10.1 years were included for the investigation of occult ALs. Twenty-three patients had occult ALs and the incidence was 25% (23/92). Fifteen extensive ALs were occult, and the proportion of extensive ALs was significantly higher in detectable ALs (97% vs. 44%, χ2 = 43.66, P < 0.001). As assessed by PR, the proportions of osteolytic destruction with reactive sclerosis (0 vs. 100%, χ2 = 111.00, P < 0.001), angular kyphosis of the affected discovertebral units or vertebral body (0 vs. 22%, χ2 = 8.86, P = 0.003), formation of an osseous bridge at the intervertebral space adjacent to ALs caused by the ossification of the anterior longitudinal ligament (38% vs. 86%, χ2 = 25.91, P < 0.001), and an abnormal height of the affected intervertebral space were all significantly lower in occult ALs (9% vs. 84%, χ2 = 60.41, P < 0.001).@*CONCLUSIONS@#Occult ALs presented with more subtle radiographic changes. Occult ALs should not be neglected, especially in the case of extensive occult ALs, because the stability of the spine might be severely impaired by these lesions.

ABSTRACT

Se conoce como enfermedad de Gibbus al colapso de la porción anterior de uno o más cuerpos vertebrales que provoca una cifosis segmentaria de ángulo agudo. En general, este tipo de deformidades son producto de infecciones tuberculosas. Uno de los principales problemas que trae apareado esta deformidad es la compresión medular. En el caso presentado, el paciente sufrió esta enfermedad como consecuencia de una infección no tuberculosa, con cifosis angular pososteomielitis, tratado con doble vía de abordaje, utilizando implantes recubiertos con nanopartículas de plata. Los resultados clínico-radiológicos fueron muy satisfactorios. Este caso presenta la conjugación de dos temas poco frecuentes en la medicina actual; por un lado, un tipo de deformidad de la columna que, rara vez, se debe a una infección no tuberculosa y, por otro lado, el implante utilizado, recubierto con nanopartículas de plata que, pese a las controversias, ofrece una nueva posibilidad de tratamiento para pacientes con un riesgo aumentado de infección asociada a implantes, y resulta de interés que sea reconocido por los cirujanos ortopedistas, puesto que existe evidencia suficiente para afirmar su capacidad para reducir la formación de biopelículas. Nivel de Evidencia: IV


Gibbus disease is the collapse of the anterior portion of one or more vertebral bodies that results in acute angle segmental kyphosis. Generally, these types of deformities are caused by tuberculosis infections. One of the main problems associated with this deformity is spinal compression. In this case, the patient presented this condition as a consequence of a non-tuberculous infection, with angular kyphosis after osteomyelitis, treated with a double approach, using implants coated with silver nanoparticles. We obtained very satisfactory clinical and radiological outcomes. This case presents the intersection of two rare topics in current medicine; on the one hand, a type of spinal deformity that rarely occurs as a consequence of a non-tuberculous infection. On the other hand, the implant used, coated with silver nanoparticles. Although there are still controversies in the literature, this implant offers a new possibility of treatment for patients who are at increased risk of implant-related infection, and it is of interest for orthopedic surgeons, since there is sufficient evidence to support its ability to reduce the formation of biofilms.

ABSTRACT

ABSTRACT Objective To present a new principle for correction of the sagittal plane of the spine through the convergent or divergent placement of monoaxial pedicle screws in this plane, associated with compression or distraction, to provide lordotizing or kyphotizing leverage force. Method A statistical mechanical study of twenty-eight fixations in synthetic spine segments was performed. In fifteen pieces, pedicle screws were applied to the ends of the segments with positioning convergent to the center of the fixation. They were attached to the straight rods and subjected to compression force. The other thirteen segments were fixed with pedicle screws in a direction divergent to the center of the fixation, attached to the straight rods, and subjected to distraction force. Results To create kyphosis in the 15 synthetic segments of the spine, the mean pre-fixation Cobb angle was - 0.7° and the mean post-fixation angle was +15°. To create lordosis in the 13 segments, the mean pre-fixation Cobb angle was +1° and the mean post-fixation angle was +18°. The difference was confirmed by statistical mechanical tests and considered significant. However, there is no relevant difference between the mean angles for lordosis and kyphosis formation. Conclusions It was concluded that the correction of the sagittal plane of the spine by applying the new instrumentation method is efficient. A statistical mechanical test confirmed that the difference in Cobb degrees between pre- and post-fixation of the synthetic spine segments was considered significant in the creation of both kyphosis and lordosis. Level of evidence II C; Statistical mechanical study of synthetic spine segments.


RESUMO Objetivo Apresentar um novo princípio para correção do plano sagital da coluna vertebral, posicionando os parafusos pediculares monoaxiais nesse plano de forma convergente ou divergente, associados à compressão ou distração, para proporcionar força em alavanca lordotizante ou cifotizante. Métodos Realizou-se um estudo de mecânica estatística de 28 fixações em segmentos de coluna sintética. Em quinze peças, foram aplicados parafusos pediculares monoaxiais nos extremos dos segmentos abordados com posicionamento no sentido convergente à fixação. Foram agregados às hastes retas e submetidos à força de compressão. Em outros treze segmentos, a fixação foi feita com parafusos pediculares monoaxiais, no sentido divergente ao centro da fixação, integrados às hastes retas e submetidos à força de distração. Resultados Para criar cifose nos 15 segmentos sintéticos da coluna vertebral, a média do ângulo de Cobb na pré-fixação foi de -0,7° e a média pós-fixação foi de +15°. Para cria lordose em 13 segmentos, a média do ângulo de Cobb na pré-fixação foi de +1° e a média pós-fixação foi de +18°. A diferença foi confirmada por testes de mecânica estatística e considerada significativa. Contudo, não existe diferença relevante entre os ângulos médio para formação da lordose e da cifose. Conclusões Conclui-se que a correção do plano sagital da coluna aplicando o novo método de instrumentação é eficiente. Confirmou-se com teste de mecânica estatística que a diferença em graus de Cobb entre o período pré e o pós-fixação dos segmentos de coluna sintética fixados foi considerada significativa, tanto na criação da cifose quanto da lordose.

ABSTRACT

La escoliosis distrófica de la neurofibromatosis se caracteriza por ser una cifoescoliosis de ángulo agudo que compromete un segmento corto de la columna vertebral y genera una gran deformidad que, sumada a los cambios distróficos de la columna, convierte a los gestos quirúrgicos para su corrección en verdaderos retos. Se presenta a un varón de 15 años con cifoescoliosis toracolumbar distrófica severa con ápice en T9, ángulo de Cobb 107° de escoliosis y 110,7° de cifosis segmentaria. Se realiza una cirugía por vía posterior en tres tiempos, mediante una resección de la columna vertebral y reemplazo con malla de titanio; se logra una corrección de la cifosis y la escoliosis del 56% y 59,8%, respectivamente. El paciente no tuvo complicaciones mayores, ni secuelas, y la evolución fue favorable. La resección de la columna vertebral es una técnica quirúrgica potente y desafiante para el manejo de la deformidad cifoescoliótica compleja necesaria para lograr el equilibrio espinal, aunque no está exenta de complicaciones, sobre todo neurológicas y pulmonares, a veces, inevitables. La calidad de vida de nuestro paciente tuvo una mejoría importante. Nivel de Evidencia: IV


Dystrophic scoliosis in neurofibromatosis is identifiable by being an acuteangle kyphoscoliosis involving a short segment of the spine and producing severe deformity that when associated with the dystrophic changes of the spine result in real surgical challenges. We report the clinical case of a 15-year male with severe dystrophic kyphoscoliosis at the thoracolumbar area, with apex at T9, scoliosis with a Cobb angle of 107 °, and segmental kyphosis of 110.7°. The patient underwent a three-stage surgery, performed through a posterior approach, involving a vertebral column resection (VCR) and titanium mesh replacement, and achieving a kyphosis correction of 56% and a scoliosis correction of 59.8%. The patient experienced no major complications nor sequelae and had a favorable course. The VCR is a powerful and demanding surgical technique that allows for the management of the complex kyphoscoliosis deformity to achieve spinal balance; however, it is not without complications, especially neurological and pulmonary complications, which may be unavoidable. Our patient's quality of life has improved significantly. Level of Evidence: IV

ABSTRACT

ABSTRACT Objective To compare the Schanz screw insertion angle and the loss of the regional kyphosis correction in thoracolumbar burst fractures following posterior short instrumentation surgery. Methods Patients with a thoracolumbar burst fracture between levels T11-L2 were divided into two groups (parallel and divergent) according to the angle formed between the Schanz screw and the vertebral plateau. Regional kyphosis was evaluated in preoperative, immediate postoperative and last follow-up radiographs. Results Of the 58 patients evaluated, 31 had a parallel assembly and 27 had a divergent assembly. When we analyzed the angle of kyphosis, no statistical difference was observed between the pre- and postoperative radiographs. However, a statistical difference in the last follow-up radiographs and in the final loss of the kyphosis correction was confirmed. Conclusion The insertion of Schanz screws with a divergent assembly presents better radiographic results with less loss of kyphosis correction angle when compared with the parallel assembly technique. Level of Evidence III; Retrospective cohort study.


RESUMO Objetivo Comparar o ângulo de inserção do pino de Schanz e os resultados da perda de correção da cifose regional nas fraturas toracolombares do tipo explosão após tratamento cirúrgico com instrumentação curta por via posterior. Métodos Os pacientes com fratura toracolombar do tipo explosão entre os níveis de T11-L2 foram divididos em dois grupos (paralelo e divergente) de acordo com o ângulo formado entre o pino de Schanz e o platô vertebral. Foi avaliada a cifose regional nas radiografias pré-operatória, pós-operatória imediata e do último acompanhamento. Resultados Dos 58 pacientes avaliados, 31 apresentaram uma montagem paralela e 27 uma montagem divergente. Ao analisarmos o ângulo da cifose, não se observou diferença estatística nas radiografias pré- e pós-operatória imediata. Porém, verificou-se uma diferença estatística nas radiografias do último acompanhamento e na perda final de correção da cifose.

ABSTRACT

ABSTRACT Objective The primary objective of this study was to analyze the prevalence of PJK in patients with neuromuscular scoliosis submitted to posterior spinal arthrodesis with instrumentation. Proximal junctional kyphosis (PJK) is a frequent phenomenon that, due to its importance, began to be studied by several authors, who laid the foundations for the radiographic definition and possible risk factors for its occurrence after long spinal arthrodesis with instrumentation. Despite the large number of PJK studies, most were related to the occurrence of adolescent idiopathic scoliosis, adult deformity and early-onset scoliosis, with few being targeted to patients with congenital and neuromuscular scoliosis. Methods In this study, data from electronic medical records of patients with neuromuscular scoliosis who underwent posterior arthrodesis with instrumentation between the years 2014 and 2016 were analyzed. Information on age, gender, pathology and radiographic measurements were extracted from this sample at the 2nd and 24th postoperative months. Results A total of 39 patients with neuromuscular scoliosis were analyzed. The sample was predominantly male (58.87%) and the mean age was 14.05 years. PJK occurred in 18 patients during the two years following surgery, with a prevalence of 46.15%. The incidence of PJK in the 2nd and 24th postoperative months was 23.1% and 30%, respectively. Conclusions A prevalence of PJK of 46.15% was found in patients with neuromuscular scoliosis treated surgically with posterior instrumentation after two years of follow-up, as compared to previous results . Level of Evidence III; Cross-sectional observational study.


RESUMO Objetivo O objetivo primário deste estudo foi analisar a prevalência de PJK nos pacientes com escoliose neuromuscular, submetidos à artrodese da coluna vertebral por via posterior com instrumentação. A cifose juncional proximal (PJK) é um fenômeno frequente que, devido à sua importância, passou a ser estudado por diversos autores, os quais lançaram as bases da definição radiográfica e possíveis fatores de risco de ocorrência depois de artrodese longa da coluna vertebral com instrumentação. Apesar da grande quantidade de estudos sobre PJK, a maioria foi relacionada quanto à ocorrência na escoliose idiopática do adolescente, na deformidade do adulto e na escoliose de início precoce, sendo poucos direcionados a pacientes com escoliose congênita e neuromuscular. Métodos Neste estudo foram analisados dados de prontuários eletrônicos de pacientes com escoliose neuromuscular submetidos à artrodese por via posterior com instrumentação, entre os anos de 2014 e 2016. Dessa amostra, foram extraídas informações pertinentes a idade, gênero, patologia e medidas radiográficas no 2º e 24º mês de pós-operatório. Resultados Um total de 39 pacientes com escoliose neuromuscular foi analisado. Na amostra houve predomínio de pacientes do sexo masculino (58,87%) e a média de idade foi de 14,05 anos. A PJK ocorreu em 18 pacientes no decorrer de dois anos de pós-operatório, com prevalência de 46,15%. A incidência de PJK no 2° e 24° mês de pós-operatório foi de 23,1% e 30%, respectivamente. Conclusões Foi encontrada prevalência de 46,15% de PJK em pacientes com escoliose neuromuscular tratados cirurgicamente com instrumentação por via posterior depois de dois anos de seguimento, confrontado resultados anteriores. Nível de Evidência III; Estudo observacional analítico transversal.

ABSTRACT

O presente estudo tem como objetivo avaliar o alinhamento post ural e a saúde musculoesquelética de praticantes adultos de natação de Uruguaiana-RS. Trata-se de um estudo transversal, descritivo diagnóstico, quantitativo. Foram incluídos 30 praticantes de natação e coletados dados de: massa corporal e estatura para cálculo do IMC (Índice de Massa Corporal), força/resistência abdominal, mobilidade/flexibilidade lombar, fotogrametria para obter ângulos sagitais da coluna vertebral (torácico e lombar) e possíveis fatores associados, com um questionário. Na análise univariada analisou-se as médias, o desvio padrão, as frequências absolutas e relativas em cada uma das variáveis estudadas, seguidas pelo cálculo do intervalo de confiança de 95% (IC95%). Para a análise bivariada, foi utilizado o teste Qui-Quadrado, no qual cada variável independente foi associada às variáveis dependentes dicotomizadas ("desvio lombar" e "desvio torácico"), sendo considerada significância de 0,05. A maioria dos avaliados apresentou excesso de peso (70%) e dor nas costas (83,3%), desvios nos ângulos lombar (60%) e torácico (66,7%). Verificou-se valores aumentados em 33,3% na lordose lombar e em 63,3% na cifose torácica nesta amostra. Houve associação significativa com os desvios no ângulo lo m bar apenas com IMC (p=0,034), prática em outra atividade física (p=0,049) e flexibilidade (p =0 ,0 47). Apenas o tempo diário na postura em pé apresentou associação significativa com a frequência de desvio sagital torácico (p=0,049). Os praticantes de natação, em sua maioria, relataram sentir dor nas co stas, m as não houve associação significativa com o alinhamento sagital dos avaliados. A hipercifose torácica, encontrada em mais da metade desta amostra, foi a alteração sagital mais comum nesta pesquisa e teve associação significativa com o tempo que os indivíduos passam em pé no seu dia-a-dia...(AU)


The aim of this study is to evaluate postural alignment and musculoskeletal health of adults who practice swimming in Uruguaiana-RS. It is a quantitative and descriptive diagnostic study . Were included 30 participants and collected data about: body mass and height to calculate BMI (Bo dy Mass Index), abdominal strength/endurance, lumbar mobility/flexibility, photogrammetry to acquire the sagittal angles of the spine (thoracic and lumbar) and questionnaire to identify possible asso ciated factors. In univariate analyses were analyzed mean and standard deviations as absolute and relative frequencies (ratios) for each variable, preceded by the calculus of 95% confidence interval (95% CI). For a biv ariate analysis, used the Chi-Square Test, and it was possible to use a parameter of significance o f 0 ,05 . T he majority of the subjects presented overweight (70%) and back pain (83.3%), as well as dev iat io n s in lumbar (60%) and thoracic angles (66.7%). It was possible to verify increased values in 33.3% on lum bar lordosis and 63.3% in thoracic kyphosis in this sample. There was only significant association wit h t he deviations in the lumbar angle only the BMI (p = 0.034), the practice in other physical activity (p = 0.049) and flexibility (p = 0.047). Considering the thoracic angle, only the daily time in standing posture presented a significant association with the frequencies of sagittal deviation (p = 0.049). Most swim m ers reported feeling back pain, but there was no significant association with sagit tal align m en t. Th oracic kyphosis was present in more than half of this sample and was the most common sagittal alteration in this study, having a significant association with the time individuals spend in standing posture daily...(AU)

ABSTRACT

OBJECTIVE@#To investigate the clinical outcome of single or double-segment pedicle subtraction osteotomy (PSO) for the treatment of old thoracolumbar osteoporotic compression fractures with kyphosis.@*METHODS@#The clinical data of 26 patients with old thoracolumbar osteoporotic compression fractures with kyphosis who underwent surgery from January 2015 to June 2017 were retrospectively analyzed. There were 12 males and 14 females, aged from 58 to 72 years old with an average of 65.6 years. The time interval from fracture to surgery was (8.2±1.5) years. According to different surgical methods, the patients were divided into single-segment PSO group (group A) and double-segment PSO group(groupB). The perioperative data, preoperative and postoperative imaging data and postoperative complications were recorded, and the Oswestry Disability Index (ODI) and visual analogue scale (VAS) were used before and after surgery to evaluate the clinical effect.@*RESULTS@#All patients were followed up for 6-24 months with an average of 14.5 months. There was a statistically significant difference in operation time and intraoperative blood loss between the two groups (0.05). The postoperative correction angle of the single segment PSO group was (33.3± 9.4) ° with the correction rate of 85.3% and the double segment PSO group was (41.0±13.5) ° with the correction rate of 92.7%, and there was statistical significance between two groups (0.05). One case of cone injury occurred in the single-segment PSO group and recovered after treatment. There were no complications of spinal cord injury in the double segment group. Loose screws occurred during surgery in three patients in the single-segment PSO group and one patient in the double-segment PSO group (<0.05). All 4 patients were re inserted with screws after using bone cement to reinforce the nail pathway. There were no complications such as anterior spinal vascular and nerve damage or osteotomy unfusion.@*CONCLUSION@#Both single-segment PSO and double-segment PSO can achieve good orthopedic and clinical effects in the treatment of old thoracolumbar osteoporotic fractures with kyphosis. For patients with correction angles greater than 40° , the double-segment PSO provides a better correction angle and is safer, but it is with longer operation time and more intraoperative bleeding.

ABSTRACT

OBJECTIVE@#To investigate how to place the anteversion of acetabular prosthesis more reasonably in patients with lumbar degenerative kyphosis.@*METHODS@#A total of 122 patients with degenerative kyphosis of lumbar spine who underwent total hip arthroplasty from December 2017 to October 2019 were included and divided into experimental group and control group, 61 cases in each group. In experimental group, there were 25 males and 36 females, with a median age of 67.0 years;the median course of disease was 46.0 months;the functional pelvic plane with acetabular anteversion was set according to different types of pelvic anterior plane bracket. In control group, there were 27 males and 34 females, with a median age of 67.0 years;the median course was 42.0 months;in control group, the anteversion was set by the traditional method. The patients were followed up for 3 months. The operation time and blood loss were recorded. The incidence of infection and dislocation within 3 months was counted. Harris score before and 3 months after operation was recorded. Functional anteversion angle of standing position was measured 3 months after operation.@*RESULTS@#Compared with control group, there was no difference in operation time and blood loss between the two groups (P=0.918, 0.381);there was no infection between two groups within 3 months after operation;there was 1 case of hip joint dislocation in the control group and no dislocation in experimental group. There was no significant difference in Harris score before and after operation. Three months later, reexamination of pelvic standing radiographs showed that the number of patients with functional anteversion of acetabular prosthesis outside the safe area was less in experimental group thanin control group (@*CONCLUSION@#According to the preoperative evaluation and classification of patients, better functional anteversion of acetabular prosthesis can be obtained with the help of pelvic anterior plane reference bracket in hip arthroplasty with lumbar degenerative kyphosis.

ABSTRACT

ABSTRACT Objective The objective of this study is to achieve a better understanding of the parameters that influence sagittal balance in a population with adolescent idiopathic scoliosis (AIS). Methods A retrospective study of 80 patients with adolescent idiopathic scoliosis (AIS) was conducted. The parameters evaluated were: age, sex, pelvic incidence (PI), sacral slop (SS), pelvic tilt (PT), sagittal balance (SB), coronal balance (CB), lumbar lordosis (LL), thoracic kyphosis (TK) divided into upper (between T1 and T5) and lower (between T5 and T12), cervical spine alignment (CSA), and Cobb's coronal angle (CCA) of primary scoliotic curvature. Results Regarding the sagittal balance, this study demonstrated a significant statistical positive correlation with cervical shape (p<0.01) and upper thoracic kyphosis (from T1 to T5) (p<0.05), but not with the other variables. LL had a strong influence on lower thoracic curvature (from T5 to T12) and was strongly influenced by the PI and SS. Conclusions Sagittal balance is a parameter that is influenced by multiple factors. In fact, it is closely related to cervical shape and the upper thoracic curvature (from T1 to T5), which in turn, is closely linked to the severity of the scoliotic kyphosis. The Cobb angle of the lower thoracic spine (from T5 to T12) is more closely correlated with the angle of lumbar lordosis than with the upper thoracic kyphosis (from T1 to T5). Level of evidence IV; Case Series.


RESUMO Objetivo O objetivo deste estudo é obter uma melhor compreensão dos parâmetros que influenciam o equilíbrio sagital em uma população com escoliose idiopática do adolescente (AIS). Métodos Foi realizado um estudo retrospectivo de 80 pacientes com escoliose idiopática do adolescente (AIS). Os parâmetros avaliados foram: idade, sexo, incidência pélvica (PI), sacral slope (SS), pelvic tilt (PT), equilíbrio sagital (SB), balanço coronal (CB), lordose lombar (LL), cifose torácica (TK) dividida em alta (entre T1 e T5) e baixa (entre T5 e T12), alinhamento da coluna cervical (CSA) e ângulo de Cobb coronal de curvatura escoliótica principal (CCA). Resultados Em relação ao equilíbrio sagital, demonstrou-se uma correlação positiva significativamente estatística com o formato da coluna cervical (p <0,01) e com o ângulo de cifose da porção superior da coluna torácica (de T1 para T5) (p <0,05), mas não com as demais variáveis. A LL exerce uma forte influência sobre a porção inferior da curvatura torácica (de T5 a T12) e é fortemente influenciada pela PI e SS. Conclusões O equilíbrio sagital é um parâmetro influenciado por múltiplos fatores. De fato, está extremamente relacionado com o formato da coluna cervical e com a coluna torácica superior (de T1 a T5) que, por sua vez, apresenta uma simbiose com a gravidade da curvatura escoliótica. O ângulo de Cobb da porção inferior da coluna torácica (de T5 a T12) apresenta uma relação maior com o ângulo da lordose lombar do que com a curvatura torácica superior (de T1 a T5). Nível de evidência IV; Série de Casos.

ABSTRACT

ABSTRACT Objective To evaluate the results after multiple posterior vertebral column resection (PVCR) in patients with severe kyphoscoliosis secondary to neurofibromatosis type 1 (NF-1). Methods Retrospective study of 4 adult male patients, mean age of 26.5 years, with severe rigid deformity, mean kyphosis of 122º and scoliosis of 88º, through clinical analysis and complementary exams. Results The mean postoperative follow-up was 27 months. Three vertebrae were resected on average. Interbody consolidation of arthrodesis was confirmed by CT in all cases. The correction rates of sagittal and coronal deformities were 54.09% and 70.45%, respectively. Prior to surgery, all patients were neurologically intact and as a post-surgical complication one patient had motor deficit (ASIA D) and pneumothorax also occurred in two patients. Conclusions The correction of severe kyphoscoliosis in adult patients with NF-1 is technically demanding and is not free of major complications. However, in view of the limited possibility of correction of these deformities, multiple-level PVCR has proved to be a safe and effective technique. Level of evidence IV; Case Series.


RESUMO Objetivo Avaliar os resultados após a ressecção vertebral posterior (RCVP) múltiplos níveis em pacientes portadores de cifoescoliose grave secundária à neufibromatose tipo 1 (NF-1). Métodos Estudo retrospectivo de 4 pacientes: adultos do sexo masculino, idade média de 26,5 anos, portadores de deformidade rígida e grave, cifose média de 122º e escoliose média de 88º, por meio da análise clínica e exames complementares. Resultados O seguimento pós-operatório médio foi de 27 meses. Foram ressecadas, em média, três vértebras. Consolidação intersomática da artrodese foi confirmada por TC em todos os casos. As taxas de correção das deformidades sagital e coronal foram de 54,09% e 70,45%%, respectivamente. Previamente à cirurgia, todos os pacientes eram neurologicamente intactos e, como complicação, um paciente apresentou déficit motor (ASIA D). Ocorreu ainda pneumotórax em dois pacientes. Conclusão A correção da cifoescoliose grave em pacientes adultos portadores NF-1 é tecnicamente exigente e não está isenta de complicações maiores. Porém, diante da possibilidade restrita de técnicas de correção dessas deformidades, a RCVP múltiplos níveis mostrou-se uma técnica segura e eficaz. Nível de evidência IV; Série de Casos

ABSTRACT

RESUMO O objetivo deste estudo foi identificar se existe correlação entre a severidade da disfunção temporomandibular (DTM) e postura corporal, bem como evidenciar as diferenças existentes na postura corporal nos diferentes graus de severidade. Foram avaliadas 71 mulheres de 18 a 35 anos quanto à severidade da DTM e à postura corporal, sendo divididas em grupo sem DTM e grupo com DTM. Foram utilizados o questionário Mandibular Function Impairment Questionnaire e o software Digital Image-Based Postural Assessment de avaliação postural por fotogrametria. Foi realizada análise estatística com ANOVA de um fator e teste de correlação Tau B de Kendall (α<0,05). Os grupos com e sem DTM apresentaram diferenças estatísticas, com tamanho de efeito grande (ŋ2>0,528), para: lordose cervical, pulsão e inclinação da pelve. Quanto à correlação da postura com a severidade da DTM, índices fracos, mas significativos, foram encontrados: ângulo da lordose cervical (τ=0,250), ângulo da cifose dorsal (τ=0,192), ângulo de inclinação pélvica (τ=−0,222) e medida de pulsão da pelve (τ=0,283). Esses resultados indicam que a lordose cervical e a pulsão da pelve se apresentam em aumento da lordose e da pulsão conforme o acréscimo da severidade da DTM, enquanto o ângulo de inclinação se apresenta em menor grau, tendendo à retroversão. Apesar das correlações fracas, os resultados evidenciam alguma relação da postura corporal com a DTM.


RESUMEN El objetivo de este estudio fue identificar si existe una correlación entre la gravedad de la disfunción temporomandibular (DTM) y la postura corporal, así como mostrar las diferencias en la postura corporal en diferentes grados de gravedad. Se evaluó la la postura corporal de 71 mujeres de 18 a 35 años, divididas en dos grupos: sin DTM y con DTM. Se utilizó el cuestionario Mandibular Function Impairment Questionnaire y el software Digital Image-Based Postural Assessment de evaluación postural por fotogrametría. Se realizó análisis estadístico con Anova de un factor y prueba de correlación Tau B de Kendall (α<0,05). Los grupos con y sin DTM presentaron diferencias estadísticas, con tamaño de efecto grande (ŋ2>0,528) para: lordosis cervical, pulsión e inclinación de la pelvis. En cuanto a la correlación de la postura con la gravedad de la DTM, índices débiles pero significativos fueron encontrados: ángulo de la lordosis cervical (τ=0,250), ángulo de la cifosis dorsal (τ=0,192), ángulo de inclinación pélvica (τ=−0,222) y medida de pulsión de la pelvis (τ=0,283). Estos resultados indican que la lordosis cervical y la pulsión de la pelvis aumentan según la gravedad de la DTM, mientras que el ángulo de inclinación se presenta en menor grado, tendiendo a la retroversión. A pesar de las correlaciones débiles, los resultados evidencian cierta relación de la postura corporal con la DTM.


ABSTRACT This study aimed to identify if there is a correlation between temporomandibular dysfunction (TMD) severity and body posture, as well as to show the differences in body posture in different degrees of severity. Seventy-one women aged 18-35 years were assessed for TMD severity and body posture and were divided into: Group without TMD and Group with TMD. We used the Mandibular Function Impairment Questionnaire and the Digital Image-Based Postural Assessment software for postural evaluation by photogrammetry. Statistical analysis was performed with one-way ANOVA and Kendall's Tau B correlation test (α<0.05). The groups with and without TMD presented statistical differences, with large effect size (ŋ2>0.528), for: cervical lordosis, drive and pelvic tilt. Regarding the correlation of posture with TMD severity, weak but significant indexes were found: cervical lordosis angle (τ=0.250), dorsal kyphosis angle (τ=0.192), pelvic tilt angle (τ=−0.222) and pelvic drive measurement (τ=0.283). These results indicate that cervical lordosis and pelvic drive are increased according to the severity of the TMD, while the pelvic tilt angle decreases, tending to a retroversion. Despite the weak correlations, the results show some relationship between body posture and TMD.

ABSTRACT

O objetivo deste estudo foi verificar a relação entre a flexibilidade da cadeia posterior, os ângulos das curvas sagitais da coluna vertebral e a presença de dor nas costas com a graduação de praticantes de Jiu-jítsu. Oitenta e dois homens com idade entre 14 e 55 anos que praticavam Jiu-jítsu duas vezes por semana com duração mínima 1 hora e 30 minutos, e com prática ininterrupta por pelo menos um mês, foram submetidos a três avaliações: (1) curvaturas sagitais da coluna vertebral por meio do flexicurva; (2) flexibilidade da cadeia posterior por meio do banco de Wells; e (3) dor nas costas por meio do questionário BackPEI adaptado. De acordo com o tempo de prática, os participantes foram divididos em dois grupos: grupo faixa branca, composto por atletas faixa branca; e grupo faixa graduada, composto pelas demais graduações. No Software SPSS 20.0 foi realizada estatística descritiva com média, desviopadrão e frequências e análise inferencial com teste de correlação de Spearman e o teste t independente (α=0,05). Os praticantes apresentaram, em média, curvaturas dentro da normalidade. Em relação à flexibilidade, a mesma foi classificada como fraca com valores semelhantes ao da população em geral. Quanto à dor nas costas, dos 82 praticantes de Jiu-jítsu, 57,3% (n=47) apresentaram dor. Foi encontrada apenas correlação fraca, positiva e significativa entre a intensidade da dor nas costas com a graduação do praticante. Foi possível verificar que a graduação dos praticantes de Jiu-jítsu se correlaciona com a intensidade de dor nas costas, de modo que quanto maior a graduação, maior é o nível da intensidade da dor...(AU)


The aim of this study was to verify the relationship between the posterior chain flexibility, the spine curvatures sagittal angles, and the presence of back pain with the Jiu-Jitsu practitioners graduation. Eighty two men with age between 14 and 55 years old who practice Jiu-Jitsu twice a week with at least 1 hour and 30 minutes, and practicing uninterruptedly for at least a month, were submitted to three evaluations: (1) sagittal spinel curvatures by using the flexicurva; (2) posterior chain flexibility by using the Wells bench; e (3) back pain by using the BackPEI adapted questionnaire. According to the time of practice, the participants were divided into two groups: white belt group, composed by white belt athletes; and graduated belt group, composed by the other graduations. Descriptive statistics was performed in the SPSS software 20.0 with average, standard deviation and frequency and inferential analysis with the Spearman correlation test and t independent test (α=0,05). The practitioners presented, on average, curvatures inside the normality parameters. About flexibility, it was classified as weak with similar to the general population values. About back pain, from those 82, 57,3% (n=47) referred pain. A significant and positive weak correlation was found between the pain intensity and the practitioners graduation. It was possible to verify that the graduation of Jiu-jítsu practitioners do correlate with the back pain intensity, in such ways that the higher the graduation, higher is the pain intensity...(AU)

ABSTRACT

ABSTRACT Objective: To analyze the clinical and radiological evolution, indications and complications of the types of osteotomies in patients with disturbed sagittal balance (SB) resulting from post-traumatic kyphosis. The SB can be measured with a plumb line from the center of the body of C7 to S1, which allows recognizing the misalignment. The imbalance can be corrected by osteotomy. Methods: Thirty patients with SB loss due to post-traumatic kyphosis were studied from January 2014 to December 2017. SPO, PSO and VCR were performed to evaluate the degree of kyphosis before and after surgery, the Oswestry questionnaire was applied and the degree of correction, the days of hospital stay and transoperative bleeding were assessed. Results: Age, 50 years, SD = 14, follow-up time: 2-3 years. We performed 11 (36.7%) osteotomies of S-P, 17 (56.7%) pedicle subtractions and 2 (6.6%) vertebrectomies. Most of the lesions were found between levels L1 and L2; the complications were dehiscence of the surgical wound in 4 patients (13.3%) and infection in 2 (6.6%). The minimum surgical time was 3 hours; the Oswestry questionnaire did not showed statistically significant difference during the preoperative period, however, considerable improvement was observed 2 years after surgery. Conclusions: The use of corrective vertebral osteotomies significantly re-establishes the spinopelvic balance altered by different pathologies. It allows correcting in a single surgery the sagittal balance, achieving corrections from 10° to 40°, depending on the type of osteotomy performed, being a safe and effective procedure, which allows to restore the spinopelvic balance, improving the quality of life of the patients. Level of Evidence IIb; Prospective cohort study.


RESUMO Objetivo: Analisar a evolução clínica, radiológica, indicações e complicações dos tipos de osteotomias em pacientes com desequilíbrio no equilíbrio sagital (ES), por uma cifose pós-traumática. O ES é o fio de prumo que vai do centro do corpo do C7 e permite reconhecer um mau alinhamento. Isso pode ser corrigido por osteotomia. Métodos: 30 pacientes foram estudados com perda no ES por cifose pós-traumático entre Janeiro de 2014 e Dezembro de 2017. SPO, PSO e VCR foram realizados, em que foi avaliado o grau de cifose pré e pós-operatório, o questionário Oswestry foi aplicado para avaliar o grau de correção, dias de internação e sangramento transoperatório. Resultados: Idade: 50 anos d.s. 14, tempo de seguimento: 2-3 anos. Foram realizados 11 (36,7%) osteotomías de SP, 17 (56,7%) subtracção de pedículo e 2 (6,6%) vertebrectomias, a maioria das lesões foi encontrada entre os níveis de L1 e L2; complicações: deiscência da ferida operatória em 4 pacientes (13,3%) e infecção em 2 (6,6%). Tempo cirúrgico mínimo: 3 horas; Oswestry questionário: não houve diferença estatisticamente significativa no pré-operatório, no entanto, no pós-operatório, em 2 anos, há uma melhoria considerável. Conclusão: A utilização de osteotomias correctiva a nível vertebral, restaura o equilíbrio espinopélvico significativamente, alterados por diferentes patologias. Corrige em um único tempo cirúrgico o equilíbrio sagital, fazendo correções da 10° a 40°, dependendo do tipo de osteotomia, sendo um procedimento seguro e eficaz, que permite espinopélvico restaurar o equilíbrio, melhorando a qualidade de vida dos pacientes. Nível de Evidência IIb; Estudo prospectivo de coorte.

ABSTRACT

STUDY DESIGN: Retrospective study. OBJECTIVES: The purpose of this study was to assess the effect of sagittal spino-pelvic alignment on the clinical symptoms of thoracolumbar kyphosis (TLK; T10-L2 Cobb's angle >20°) in osteoporotic patients. SUMMARY OF LITERATURE REVIEW: Few studies have investigated the clinical symptoms and radiological features of TLK caused by degenerative changes. There is also controversy over whether clinical symptoms will deteriorate in patients with TLK or which treatment should be chosen according to the degree of TLK. MATERIALS AND METHODS: From May 2005 to May 2016, we reviewed 75 patients who were diagnosed with TLK (T10-L2 Cobb's angle >20°) and osteoporosis. Patients were excluded from the study if they had neurological symptoms, underlying spinal disorders, or unstable vertebral fractures. Fifty patients with TLK due to an osteoporotic vertebral compression fracture (group F) and 25 patients with senile TLK (group S) were assessed by clinical symptoms and radiological parameters. Thoracolumbar kyphosis angle and sagittal vertical axis (SVA) were also analyzed. Clinical symptoms were assessed using a visual analogue scale (VAS) and the Oswestry Disability Index (ODI). RESULTS: There were no significant differences in clinical symptoms (VAS, ODI) and radiological parameters between groups F and S, or according to the degree of TLK(20°–30°, 30°–40°, >40°). Clinical symptoms were significantly more severe in patients with sagittal imbalance (SVA >5 cm) than in those with sagittal balance. CONCLUSIONS: Sagittal imbalance is a more important factor affecting clinical symptoms than the cause or the degree of TLK. Therefore, sagittal imbalance should be considered in the management of TLK in osteoporotic patients.
