ABSTRACT

This study aimed to investigate the sagittal spinal-pelvic morphological changes, as well as the relationship between pelvic anatomical changes and the spinal-pelvic plane in patients with adolescent idiopathic scoliosis (AIS), in order to provide guidelines for orthopedic surgery in AIS. X-ray data were collected for retrospective analysis from 30 patients diagnosed as AIS in the Departments of Radiology at the Second Affiliated Hospital of Inner Mongolia Medical University and the Inner Mongolia International Mongolian Medical Hospital from April 2014 to November 2018, along with 30 normal adolescents as control. Pelvic parameters, including pelvic incidence (PI), pelvic tilt (PT), and sacral slope (SS), a spinal parameter, lumbar lordosis (LL), and anatomical parameters, including sacral width (SW) and femoral head- sacrum distance (FH-S), were measured. The spinal-pelvic parameters were compared between AIS patients and normal controls and also between male and female AIS patients. Pearson correlation was performed to analyze correlation between spinal-pelvic parameters and between spinal-pelvic parameters and anatomical parameters in both AIS patients and normal controls. PT was significantly lower in AIS patients than in normal controls (P < 0.05), whereas no significant difference was found in the other spinal-pelvic parameters, i. e. , LL, PI, and SS. There was a significant difference in PT between sexes in AIS patients. SS was significantly correlated with LL in EIA patients (P < 0.05, r > 0.5). SS was significantly correlated with LL and PI, and PT with LL, PI, and SS in normal controls (all P < 0.05), and there was no significant correlation between the other sagittal spinal-pelvic parameters (P > 0.05). FH-S was significantly correlated with LL, PI, SS, and PT in AIS patients (all P < 0.05). AIS affects some of the sagittal spinalpelvic parameters and anatomical parameters. In AIS, there is a significant correlation between the spinal-pelvic parameters, and the anatomical parameter is significantly correlated with multiple spinal-pelvic parameters.


Este estudio tuvo como objetivo investigar los cambios morfológicos sagitales de la columna vertebral-pélvica, así como la relación entre los cambios anatómicos pélvicos y el plano espinal-pélvico en pacientes con escoliosis idiopática adolescente (EIA), con el fin de proporcionar pautas para la cirugía ortopédica en AIS. Se obtuvieron los datos de rayos X para el análisis retrospectivo de 30 pacientes diagnosticados como EIA en los Departamentos de Radiología del hospital Second Affiliated Hospital of Inner Mongolia Medical University y el hospital Inner Mongolia International Mongolian Medical Hospital, desde abril de 2014 hasta noviembre del 2018, junto con 30 adolescentes normales como control. Se midieron los parámetros pélvicos, que incluyeron incidencia pélvica (IP), inclinación pélvica (P) y pendiente sacra (PS), un parámetro espinal, lordosis lumbar (LL) y parámetros anatómicos, que incluyeron el ancho sacro (AS) y la distancia del sacro cabeza femoral (FH-S). Los parámetros espinalpélvicos se compararon entre los pacientes con EIA y los controles normales, como también entre pacientes con EIA masculinos y femeninos. La correlación de Pearson se realizó para analizar la correlación entre los parámetros espinal-pélvicos y entre los parámetros espinal-pélvicos y los parámetros anatómicos tanto en pacientes con EIA como en controles normales. PT fue significativamente menor en pacientes con EIA que en los controles normales (P <0,05), mientras que no se encontraron diferencias significativas en los otros parámetros espinal-pélvicos, i. mi. , LL, PI y SS. Hubo una diferencia significativa en PT en pacientes de ambos sexos con EIA. SS se correlacionó significativamente con LL en pacientes con EIA (P <0,05, r> 0,5). SS se correlacionó significativamente con LL y PI, y PT con LL, PI y SS en controles normales (todos P <0,05), y no hubo correlación significativa entre los otros parámetros sagitales de la columna vertebral-pélvica (P> 0,05) FH-S se correlacionó significativamente con LL, PI, SS y PT en pacientes con EIA (todos P <0,05). EIA afecta algunos de los parámetros sagitales de la columna vertebral-pélvica y los parámetros anatómicos. En EIA, existe una correlación significativa entre los parámetros espinal-pélvicos, y el parámetro anatómico se correlaciona significativamente con múltiples parámetros espinales-pélvicos.

ABSTRACT

ABSTRACT Objective: To evaluate the chest wall shape in patients with adolescent idiopathic scoliosis (AIS) in comparison to healthy subjects and the association between the chest wall shape with the spine deformity and lung function in patients with AIS. Methods: This cross-sectional study enrolled 30 AIS patients and 20 healthy subjects aged 11-18 years old. The Cobb angle evaluation was performed in AIS patients. The chest wall shape was assessed by the photogrammetry method, using the Postural Assessment Software (PAS). We created thoracic markers shaped as angles (A) and distances (D), as follows: A2 (right acromion/xiphoid/left acromion), A4L (angle formed between the outer point of the smallest waist circumference and its upper and lower edges on the left side), A7 (angle formed by the intersection of the tangent segments of the upper and lower scapulae angles), D1R/D1L [distance between the xiphoid process and the last false rib on the right (R) and left (L) sides], and D3 (distance between xiphoid process and anterior superior iliac spine). Results: The thoracic markers A2 and A7 were significantly higher, while the A4L and D1R/D1L were significantly reduced in the AIS group compared to the control. Moderate correlations were found between: A2 and the main and proximal thoracic Cobb angles (r=0.50, r=0.47, respectively); D1R/D1L and the main thoracic Cobb angle (r=- 0.40); and the forced expiratory volume in the first second (FEV1) and D3R (r=0.47). Conclusions: The photogrammetry method was able to detect chest wall changes in AIS patients, besides presenting correlation between Cobb angles and lung function.


RESUMO Objetivo: Avaliar o formato da caixa torácica em pacientes com escoliose idiopática do adolescente (EIA), comparando-os com indivíduos saudáveis e analisar a associação do formato da caixa torácica com a deformidade da coluna vertebral e função pulmonar em pacientes com EIA. Métodos: Estudo transversal que avaliou 30 pacientes com EIA e 20 indivíduos saudáveis com idade entre 11 e 18 anos. O ângulo de Cobb foi avaliado em pacientes com EIA. O formato da caixa torácica foi analisado pelo método da fotogrametria, utilizando o Software para Avaliação Postural (SAPO). Foram criados marcadores torácicos descritos como ângulos (A)e distâncias (D): A2 (acrômio direito/processo xifoide/acrômio esquerdo), A4E (ângulo formado entre o ponto externo da menor circunferência da cintura e suas bordas superior e inferior do lado esquerdo), A7 (ângulo formado pela interseção das retas tangentes aos ângulos superior e inferior das escápulas), D1D/D1E [distância entre o processo xifoide e a última costela falsa nos lados direito (D) e esquerdo (E)] e D3 (distância entre o processo xifoide e a espinha ilíaca anterossuperior). Resultados: Os marcadores torácicos A2 e A7 foram significativamente maiores, enquanto o A4E e o D1D/D1E foram significativamente menores no grupo EIA em relação ao controle. Foram encontradas correlações moderadas entre: A2 e os ângulos de Cobb torácico principal e proximal (r=0,50 e r=0,47, respectivamente); D1D/D1E e o ângulo de Cobb torácico principal (r=-0,40); e o volume expiratório forçado no primeiro segundo (VEF1) e D3D (r=0,47). Conclusões: O método da fotogrametria detectou alterações na caixa torácica de pacientes com EIA, além de apresentar correlações significativas entre os ângulos de Cobb e a função pulmonar.

ABSTRACT

ABSTRACT Despite many years of dedicated research into the etiopathogenesis of adolescent idiopathic scoliosis, there is still no single distinct cause for this puzzling condition. In this overview, we attempt to link knowledge on the complex three-dimensional pathoanatomy of AIS, based on our ongoing research in this field, with etiopathogenic questions. Evidence from multiple recent cross-sectional imaging studies is provided that supports the hypothesis that AIS has an intrinsic biomechanical basis: an imbalance between the biomechanical loading of the upright human spine due to its unique sagittal configuration on the one hand, and the body's compensating mechanisms on the other. The question that remains in the etiology of AIS, and the focus of our ongoing research, is to determine what causes or induces this imbalance.


RESUMO Apesar dos muitos anos de pesquisa dedicada à etiopatogenia da escoliose idiopática do adolescente, ainda não existe uma única causa distinta para essa afecção intrigante. Nesta visão geral, tentamos fazer a ligação do conhecimento sobre a complexa anatomia patológica tridimensional da EIA, com base em nossas pesquisas em andamento nessa área, com as questões da etiopatogenia da doença. As evidências dos diversos estudos transversais recentes são apresentadas e corroboram a hipótese de que a EIA tem base biomecânica intrínseca: o desequilíbrio entre a carga biomecânica devido à sua configuração sagital única por um lado, e os mecanismos compensatórios do corpo, por outro. Ainda há dúvidas sobre a etiologia da EIA e o foco de nossa pesquisa em andamento é determinar o que causa ou induz esse desequilíbrio.

ABSTRACT

OBJECTIVES: The objective of this study was to evaluate whether the severity of deformities in patients with adolescent idiopathic scoliosis contributes to patients’ decision regarding whether to undergo an operation. METHODS: We evaluated body image factors in adolescent idiopathic scoliosis patients. We evaluated the magnitude of the main scoliotic curve, gibbosity (magnitude and location), shoulder height asymmetry and patient’s age. We analyzed the correlation of these data with the number of years the patient was willing to trade for surgery, as measured by the time-trade-off method. RESULTS: A total of 52 patients were studied. We did not find a correlation between any of the parameters that were studied and the number of years that the patient would trade for the surgery. CONCLUSIONS: The magnitude of body deformities in patients with adolescent idiopathic scoliosis does not interfere with the decision to undertake surgical treatment.

ABSTRACT

Abstract: The Nevoid Basal Cell Carcinoma Syndrome (NBCCS) is an uncommon disorder caused by a mutation in Patched, tumor suppressor gene. It is mainly characterized by numerous early onset basal cell carcinomas, odontogenic cysts of jaw and skeletal abnormalities. Due to the wide clinical spectrum, treatment and management of its modalities are not standardized and should be individualized and monitored by a multidisciplinary team. We report a typical case in a 30-year-old man with multiple basal cell carcinomas, keratotic pits of palmar creases and bifid ribs, with a history of several corrective surgeries for keratocystic odontogenic tumors, among other lesions characteristic of the syndrome.

ABSTRACT

BACKGROUND: Patients with idiopathic scoliosis are exposed to approximately 25 radiographic examinations of their spine throughout the clinical follow-up using the Cobb angle. Several non-invasive and radiation-free methods have been proposed to measure scoliotic deformities, including the scoliometer. OBJECTIVES: To measure the intra- and interrater reliability of the scoliometer measurements, to assess the correlation of the values obtained by the scoliometer measurements with the Cobb angles obtained by radiography, and to assess the sensitivity and specificity of the scoliometer measurements for the different diagnostic criteria for the referral of idiopathic scoliosis. METHOD: Sixty-four patients were selected for the study: half with idiopathic scoliosis and half without. The 17 levels of the spine of each volunteer were measured with a scoliometer in the forward bending position. The measurements were performed three times on 42 volunteers by two different raters to obtain data for calculating the reliability values. Anteroposterior radiographs were taken to determine the Cobb angles, which were then compared with the highest trunk rotation value. Sensitivity and specificity were evaluated using radiograph criteria for referral: a Cobb angle of 10º and axial trunk rotation values between 5º and 10º. RESULTS: Excellent intrarater reliability values and very good interrater reliability values were obtained. The correlation between the scoliometer measurements and radiograph analyses was considered good (r=0.7, p<0.05). The highest sensitivity value was for a trunk rotation of 5º at 87%. CONCLUSIONS: The scoliometer measurements showed a good correlation with the radiographic measurements. .

ABSTRACT

OBJETIVO: Identificar os sinais radiográficos preditivos de descompensação do tronco em pacientes com EIA King II (Lenke B e C) submetidos a artrodese torácica seletiva com material de terceira geração. MÉTODOS: Foram avaliadas retrospectivamente as radiografias pré-operatórias e do último acompanhamento de 22 pacientes. A amostra foi dividida em dois grupos: pacientes compensados após o tratamento (n=18) e os pacientes que apresentaram descompensação coronal (n=4). Esses dois grupos foram comparados para analisar possíveis critérios radiográficos pré-operatórios preditivos da descompensação do tronco. RESULTADOS: Os pacientes que evoluíram com descompensação coronal do tronco apresentaram maior valor angular, maior translação e maior rotação da vértebra apical da curva lombar e maior obliqüidade de L4 em relação à pelve. Além disso, a relação entre a curva torácica para os critérios de valor angular, TVA e RVA foi menor, quando comparadas com os pacientes com boa evolução. CONCLUSÕES: Curvas lombares compensatórias com valor angular semelhante à curva torácica principal, com translação e rotação da vértebra apical elevadas e grande inclinação de L4 apresentam alta probabilidade de descompensação do tronco após o tratamento cirúrgico. O número pequeno de pacientes descompensados não permitiu definir valores preditivos destas variáveis.


OBJECTIVE: To identify the predictive radiographic signs of trunk decompensation in King II AIS patients (Lenke B and C) who underwent selective thoracic arthrodesis with third generation material. METHODS: A retrospective analysis was carried out of the preoperative radiographies, and those from the most recent follow-up, of twenty-two patients. The sample was divided in two groups: patients compensated after treatment (n=18) and patients who presented coronal decompensation (n=4). The two groups were compared to analyse possible postoperative predictive radiographic criteria of trunk decompensation. RESULTS: The patients who developed coronal trunk decompensation showed a greater angular value, greater apical vertebral translation (AVT) and rotation (AVR) of the lumbar curve, and greater L4 obliquity in relation to the pelvis. Furthermore, the relationship between the thoracic curve AVT and AVR, for the angular value criteria, was smaller than for the patients with good evolution. CONCLUSIONS: Compensatory lumbar curves with similar angular value to the main thoracic curve, with greater translation and rotation of the apical vertebra and greater L4 slope, have a high probability of trunk decompensation after this surgical treatment. The small number of decompensated patients did not enable any predictive values of these variables to be defined.

ABSTRACT

OBJECTIVE: To introduce the " virtual goniometer" , a method of measuring angles on digital images using Microsoft PowerPoint, a readily available and inexpensive software programme. METHODS: Twenty-six X-rays of scoliosis curves were photographed with a digital camera. Six examiners measured the angles of curvature on their computers using the goniometer (Set 1). Under a blinded protocol, repeated measurements on these digitalized X-rays were done three weeks later (Set 2). Intra-observer differences were analyzed. To assess validity, four examiners also measured the angles using the Cobb method. Measurements achieved by both methods were analyzed by the paired samples t-test. To assess inter-observer differences, the Pearson correlation coefficient was calculated. RESULTS: Pearson correlation coefficients were significant, r (24) $ 0.975, p < 0.001. For intra-observer variability, the average 95% CI range was 2.23 degrees between Set 1 and Set 2. The average 95% CI range was 2.38 degrees for the difference between the digital and Cobb methods. CONCLUSIONS: Clinicians using this technique can reliably assume that repeated measurements of scoliosis curvatures will vary in the range of less than 3 degrees. The 95% CI range for intra-observer variability, an index of the technique’s repeatability, was $ 2.4 degrees. A high correlation of measurements can also be expected between different observers with the goniometer. This new technique allows practitioners to utilize an easily accessible computer programme to evaluate angular deformities on digitalized radiographic images accurately and hence reliably make clinical decisions based on these measurements.


OBJETIVOS: Introducir el " goniómetro virtual" , un método de medición de ángulos sobre imágenes digitales usando Microsoft Power Point, un programa de software no costoso y fácilmente disponible. MÉTODOS: Veintiséis rayos X de curvas de escoliosis fueron fotografiados con una cámara digital. Seis examinadores midieron los ángulos de curvatura en sus computadoras usando el goniómetro (Set 1). Bajo un protocolo ciego, se realizaron mediciones repetidas de estos rayos X digitalizados, tres semanas más tarde (Set 2). Se analizaron las diferencias intra-observador. Para evaluar la validez, cuatro examinadores también midieron los ángulos usando el método de Cobb. Las mediciones logradas por ambos métodos fueron analizadas mediante la prueba de t de muestras pareadas. Para evaluar las diferencias inter-observador, se calculó el coeficiente de correlación de Pearson. RESULTADOS: Los coeficientes de correlación de Pearson fueron significativos, r (24) $ 0.975, p < 0.001. Para la variabilidad intra-observador, el 95% promedio del rango del CI fue de 2.23 grados entre el Set 1 y el Set 2. El 95% promedio del rango del CI fue de 2.38 grados para la diferencia entre el método digital y el método de Cobb. CONCLUSIONES: Los clínicos que usen esta técnica, pueden con toda confiabilidad asumir que las mediciones repetidas de las curvaturas de escoliosis variarán en un rango menor de 3 grados. El 95% del rango del CI para la variabilidad intra-observador Â- un índice de la repetibilidad de la técnica Â- fue $ 2.4 grados. También puede esperarse una alta correlación de las mediciones, entre diferentes observadores con el goniómetro. Esta nueva técnica permite a los practicantes utilizar un programa de computación fácilmente accesible a fin de evaluar con precisión las deformidades angulares en imágenes radiográficas digitalizadas, y tomar por lo tanto decisiones clínicas de modo confiable a partir de estas mediciones.

ABSTRACT

Os autores estudaram as alteraçöes dos músculos rotadores do dorso torácicos e lombares de pacientes com escoliose idiopática do adolescente submetidos a tratamento cirúrgico da deformidade, utilizando a biópsia muscular. Ao todo foram estudados 32 pacientes do sexo feminino. Os fragmentos musculares foram coletados no ápice da deformidade, no lado côncavo e convexo. As biópsias musculares foram tratadas pela técnica histoquímica de análise dos fragmentos musculares. Os resultados das biópsias musculares mostraram que em 100 por cento dos pacientes os músculos estavam alterados, independentemente do lado. As lesöes mais freqüentemente observadas foram type grouping e predominância de fibras do tipo I. Esses achados mostram que o padräo neurogênico constituiu a principal manifestaçäo encontrada nos músculos rotadores do dorso dos pacientes com escoliose idiopática do adolescente estudados, sugerindo uma forma frustra de amiotrofia espinhal do tipo III.
