“…The Milwaukee topography instrument presented excellent inter-evaluator reproducibility for thoracic kyphosis and weak inter-evaluator reproducibility for lumbar lordosis. However, in determining repeatability, we found lower levels for thoracic kyphosis, with correlation ranging from moderate to excellent and excellent for lumbar lordosis 26 . The Quantec topography system was also evaluated as for repeatability; however, only the standard deviation values of these measures were presented, and we observed standard deviation of ±4.2° for lumbar lordosis and standard deviation of ±3.6° for thoracic kyphosis 16 .…”

RESUMO O objetivo deste estudo foi verificar a validade concorrente, a repetibilidade e a reprodutibilidade interavaliador do sistema Vert 3D na avaliação das curvaturas torácica e lombar de crianças com diferentes perfis nutricionais. Participaram 115 crianças, divididas em três grupos: baixo peso e eutróficos, sobrepeso e obesos. Cada criança fez uma radiografia panorâmica da coluna vertebral na incidência perfil direito, de onde foram obtidos os ângulos de Cobb de cifose torácica e lordose lombar. Além disso, cada participante foi avaliada com o sistema de topografia Vert 3D cinco vezes no mesmo dia, imediatamente após a avaliação radiológica. As avaliações foram realizadas por três avaliadores independentes e forneceram os ângulos Vert de cifose torácica e lordose lombar. No software SPSS os dados foram submetidos ao Coeficiente de Correlação Produto-momento de Pearson, Coeficiente de Correlação Intraclasse, teste t pareado e ANOVA one-way. O sistema Vert 3D apresentou excelentes níveis de repetibilidade e reprodutibilidade interavaliador, independente do perfil nutricional avaliado, para os ângulos de cifose torácica e lordose lombar, mas apresentou correlação fraca com o ângulo de Cobb para cifose torácica e moderada para lordose lombar. Esses resultados sinalizam que esse sistema pode ser utilizado no acompanhamento clínico de alterações posturais da coluna vertebral no plano sagital de crianças de todos os perfis nutricionais, mas não pode ser utilizado como forma de diagnóstico ou com o objetivo de estimar o ângulo de Cobb.

“…In most studies, subjects younger than 18 years were used. Regarding the sex of the subjects, two [ 36 , 39 , 49 ] of the eighteen included studies did not specify the sex of the subjects. The remaining sixteen studies included male and female subjects and more female than male subjects, which is consistent with gender differences in the onset of scoliosis.…”

Background. Surface topography (ST) is one of the methods in scoliosis assessment. This study aimed to systematically review the reliability and validity of the ST measurements for assessing scoliosis. Methods. A literature search of four databases was performed and is reported following PRISMA guidelines. The methodological quality was evaluated using Brink and Louw appraisal tool and data extraction was performed. The results were analyzed and synthesized qualitatively using the level of evidence method. Results. Eighteen studies were included and analyzed. Four were evaluated for reliability, six for validity, and eight for reliability and validity. The methodological quality of fourteen studies was high. Good to excellent intra-investigator reliability was shown on asymmetry, sagittal, horizontal, and most frontal ST measurements (evidence level: strong). Asymmetry and most frontal, sagittal, horizontal ST measurements showed good to excellent inter-investigator reliability (evidence level: moderate). When comparing corresponding ST and radiological measurements, good to strong validity was shown on most frontal, sagittal, and asymmetry measurements (evidence level: strong). Formetric measurements had good intra-investigator reliability and validity (evidence level: strong). Conclusions. Most asymmetry, sagittal, and frontal ST measurements showed satisfactory reliability and validity. Horizontal ST measurements showed good reliability and poor validity. The ST technique may have great potential in assessing scoliosis, especially in reducing radiation exposure and performing cosmetic assessments.

Performance of Surface Topography Systems in Scoliosis Management: A Narrative Review

IntroductionThe aesthetic appearance of the torso is the foremost concern of scoliotic patients, which, if not addressed, could adversely affect their life quality. The Cobb angle limitation in describing three-dimensional (3D) deformities of the spine and its associated ionizing radiation motivated clinicians to implement noninvasive surface topography (ST) methods for monitoring scoliosis. This study aimed to review the accuracy of the most commonly used ST systems and their ST parameters in predicting and monitoring scoliosis.Materials and MethodsThe scientific databases were used to search for the studies considering the validity and reliability of different ST methods published in English from 1970 to July 2020.ResultsOf 221 found publications, 41 journal publications were evaluated for this review. The accuracy of ST methods was affected by light source quality, acquisition time, and postural sway. Some ST parameters resulted in a high correlation with radiographic measurements and classified scoliosis deformities into mild, moderate, and severe. Some ST parameters may not effectively predict the Cobb angle but could monitor curve progression accurately. Representing spine deformities in the lumbar section and subjects with higher body mass index was associated with more significant errors due to thicker soft tissues around the spine.ConclusionsAccording to the present review, ST systems could complement radiography measurements and provide valuable insights into different aspects of internal and external deformity; however, they have not reached a state that can replace radiography in the management of scoliosis.Clinical RelevanceThe present study helps clinicians choose the most appropriate ST methods for predicting and monitoring scoliotic curves and torso asymmetry evaluations.
