Resumo: ObjectiveTo analyze intra and interobserver agreement of two radiographic methods for evaluation of posterolateral lumbar arthrodesis. MethodTwenty patients undergoing instrumented posterolateral fusion were evaluated by anteroposterior and dynamic lateral radiographs in maximal flexion and extension. The images were evaluated initially by 6 orthopedic surgeons, and after 8 weeks, reassessed by 4 of them, totaling 400 radiographic measurements. Intra and interobserver reliability were analyzed using the Kappa coefficient and Landis and Koch criteria. ResultIntra and interobserver agreement regarding anteroposterior radiographs were, respectively, 76 and 63%. On lateral views, these values were 78 and 84%, respectively. However, the Kappa analysis showed poor intra and interobserver agreement in most cases, regardless of the radiographic method used. ConclusionThere was poor intra and interobserver agreement in the evaluation of lumbosacral fusion by plain film in anteroposterior and dynamic lateral views, with no statistical superiority between the methods.

Métodos Foram submetidos à fusão posterolateral instrumentada 20 pacientes, avaliados por meio de radiografias anteroposteriores e laterais, em flexão e extensão máximas. As imagens foram avaliadas inicialmente por 6 médicos ortopedistas e, após 8 semanas, reavaliadas por 4 deles, totalizando 400 mensurações radiográficas. Foi realizada análise de confiabilidade intra e interobservador por meio do coeficiente Kappa e pelos critérios de Landis e Koch. Resultados A porcentagem de concordância intra e interobservadores para radiografias anteroposteriores foi, respectivamente, 76 e 63%. Na incidência radiográfica lateral, esses valores foram de 78 e 84%, respectivamente. Entretanto, a análise pelo método de Kappa mostrou concordância fraca e ruim intra e interobservadores para a maior parte dos casos, independentemente do método radiográfico utilizado. Conclusão observou-se fraca concordância intra e interobservadores na avaliação da fusão lombossacra por meio de radiografias simples, nas incidências anteroposterior e laterais dinâmicas, não havendo superioridade estatística entre os métodos estudados.Santa Casa da Misericórdia de SantosFaculdade de Medicina do ABCUniversidade Federal de São Paulo (UNIFESP)UNIFESP, ISS, Santos, BrazilSciELOInstituto Israelita de Ensino e Pesquisa Albert EinsteinSanta Casa da Misericórdia de SantosFaculdade de Medicina do ABCUniversidade Federal de São Paulo (UNIFESP)Gotfryd, Alberto OfenhejmPomar, Felipe de MoraesCarneiro Neto, Nicola JorgeFranzin, Fernando JoséRodrigues, Luciano Miller ReisPoletto, Patrícia Rios [UNIFESP]2015-06-14T13:47:02Z2015-06-14T13:47:02Z2014-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersion198-203application/pdfhttp://dx.doi.org/10.1590/S1679-45082014AO2964Einstein (São Paulo).
