RESUMO
BACKGROUND: Elbow immobilization due to fractures of the upper limb is frequent in paediatric patients. Proper follow-up is critical to assess elbow functional recovery. Telemedicine can be an option for remote monitoring of these patients. The purpose of this study was to compare personal and virtual evaluation of elbow range of motion after long arm cast withdrawal in paediatric patients. METHODS: An observational cross-sectional study was carried out which included all paediatric patients with elbow immobilization in long arm casts treated at our centre. After cast withdrawal, elbow range of motion was evaluated by telemedicine and in office consultation in all four movements (flexion, extension, pronation and supination). RESULTS: Ninety-three patients met the selection criteria. Median age at time of immobilization was 8 years. Mean elbow immobilization time was 23 days (range 18-56 days). When comparing office and remote measurements, no statistical differences were found for any of the four elbow movements measured in our study. CONCLUSIONS: Remote evaluation of elbow range of motion by telemedicine is technically feasible. We evaluated elbow range of motion in paediatric patients after immobilization and we did not find differences between digital and in office measurements. The results were similar to those obtained through assessment in the office. We believe that this is a useful tool to facilitate remote patient follow-up.

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.

Introducción: La fotografía digital de radiografías puede generar distorsiones angulares en las imágenes. No está publicado si estas alteraciones pueden afectar las mediciones de los ángulos de Cobb. Objetivo: Evaluar la reproducibilidad del ángulo de Cobb con la fotografía digital de espinogramas de 30 x 90 cm en escoliosis del adulto. Materiales y Métodos: Se eligieron al azar 20 espinogramas preoperatorios de pacientes con escoliosis del adulto para evaluar prospectivamente. Los espinogramas fueron escaneados y sus imágenes digitales se consideraron como controles. Se analizó la discrepancia intraobservador, interobservador, intercámara e intracámara, con tres cámaras digitales y dos observadores que realizaron ocho sesiones fotográficas a cada espinograma. Se midieron los ángulos con Adobe Photoshop« sobre las imágenes digitales y se los analizó con el coeficiente de correlación de Pearson. Resultados: El promedio de los ángulos de Cobb torácicos y lumbares del escáner, las cámaras 1, 2 y 3 fue de 37,9; 37,8; 37,7; 37,5; 53,2; 53,1; 53,3; 52,9, respectivamente. La correlación interobservador e intraobservador fue extremadamente alta, así como entre las cámaras y el escáner. Conclusión: El ángulo de Cobb se puede medir luego de la fotografía digital de espinogramas de 30 x 90 cm, con alta reproducibilidad entre diferentes cámaras y observadores.(AU)
Background: Digital photography to radiographs can generate angular distortions to the images. It is not published if these distortions can affect the lines used for Cobb measurements in routine practice. Objective: To analyze reliability for coronal Cobb angle measurements of digitally acquired photograph to the 30 x 90 cm plain films in adult scoliosis. Methods: Twenty anteroposterior long-cassette scoliosis radiographs from adult patients who were operated on in one institution were randomly selected and prospectively studied. The endplates of the curves were selected and marked by one observer. The radiographs were scanned and the digital images were used as controls. The variability of the measurements was evaluated with three digital cameras and two observers making eight photographic sessions to each long-film. Over the digital images the Cobb angles were measured using Adobe Photoshop« and they were analyzed with the Pearson correlation coefficient. Results: The overall mean thoracic and lumbar Cobb angles for the scanned, camera 1, 2 and 3 were 37.9, 37.8, 37.7, 37.5, 53.2, 53.1, 53.3, 52.9, respectively. The interobserver and intraobserver agreement was extremely high, as well as across cameras and scanner. Conclusion: The Cobb angle can be measured after digitally photographed films with high reliability among different cameras and observers.(AU)
RESUMO
This study proposed the development of a new clinical tool capable of quantifying the movements of opening-closing, protrusion and laterotrusion of the mandible. These movements are important for the clinical evaluation of the temporomandibular function and muscles involved in mastication. Unlike current commercial systems, the proposed system employs a low-cost video camera and a computer program that is used for reconstructing the trajectory of a reflective marker that is fixed on the mandible. In order to illustrate the clinical application of this tool, a clinical experiment consisting on the evaluation of the mandibular movements of 12 subjects was conducted. The results of this study were compatible with those found in the literature with the advantage of using a low cost, simple, non-invasive, and flexible tool customized for the needs of the practical clinic.
