Concordância interobservador na avaliação de lesões do tendão subescapular usando imagens de Ressonância Nuclear Magnética

Abstract

Introdução: As lesões do tendão musculo subescapular (TMSE) do manguito rotador passaram a ter aumento de sua incidência com as avançadas técnicas de diagnostico por imagem e artroscópicas. A Ressonância Nuclear Magnética (RM) apresenta boa sensibilidade e especificidade permitindo adequada acurácia diagnóstico. Objetivo: avaliação da concordância interobservador da RM para Lesões do TMSE comparada à artroscopia. Métodologia: 49 pacientes sintomáticos foram submetidos à RM para diagnóstico de lesão do TMSE e avaliação da Classificação de Lafosse, tendo sua concordância avaliada através da Artroscopia diagnostica. Resultados: A acurácia global foi 68% para concordância diagnóstica da Lesão do TMSE e 57,1% para concordância na classificação de Lafosse. Discussão: obteve-se concordância para o diagnóstico de Lesão ou ausência de Lesão do TMSE de 0,49 e a concordância para a Classificação de Lafosse foi de 0,30. Conclusão: o diagnóstico da lesão do TMSE através da RM é de difícil realização.

Descritores: Manguito Rotador; Artroscopia; Imagem por Ressonância Magnética.
