          Abstract

          OBJETIVO: A proposta do trabalho é avaliar a acurácia da radiografia simples, ultrassonografia e ressonância nuclear magnética no diagnóstico das lesões do manguito rotador, comparando-os com os achados em cirurgias abertas ou artroscópicas. Métodos: Foram avaliados protocolos do Serviço de Cirurgia do Ombro e Cotovelo dos pacientes submetidos ao tratamento cirúrgico por lesão de manguito rotador diagnosticados por radiografia, ultrassom e/ou ressonância no período de 2002-2007. Com base nos dados coletados, analisamos a sensibilidade, especificidade, valor preditivo positivo, valor preditivo negativo e acurácia destes exames complementares, comparados aos achados durante os procedimentos cirúrgicos. RESULTADOS: Foram incluídos no estudo 147 pacientes, com média de idade de 46,09 anos. Todos os pacientes estudados haviam realizado um exame de radiografia, 101 apresentavam ultrassonografia e 72 pacientes realizaram ressonância magnética. Encontramos sensibilidade de 13,8%, especificidade de 2,6% e acurácia de 30% com a radiografia; sensibilidade de 57,6%, especificidade de 29,6 e acurácia de 51,4% com o ultrassom; e sensibilidade de 86,6%, especificidade de 22,2% e acurácia de 63,3% com a ressonância. CONCLUSÃO: A radiografia se mostrou um exame específico quando apresentou sinal do espelho. A ressonância e a ultrassonografia se mostraram métodos confiáveis apresentando elevada acurácia no diagnóstico das lesões do manguito rotador.

          OBJECTIVE: This paper proposes to evaluate the accuracy of x-rays, ultrasounds, and nuclear magnetic resonance in the diagnosis of rotator cuff injuries, comparing their findings with open surgery or arthroscopic findings. METHODS: Shoulder and Elbow Surgery Department protocols for patients undergoing surgical treatment for rotator cuff injury diagnosed by x-ray, ultrasound and/or resonance in our clinic, that were between 2002 and 2007. Based on the data collected, we analyzed the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of these complementary exams, compared to the findings from surgical procedures. RESULTS: The study included 147 patients with a mean age of 46.09 years. Every patient had completed an x-ray exam, 101 had had an ultrasound and 72 patients underwent magnetic resonance. We found a sensitivity of 13.8%, specificity of 2.6%, and accuracy of 30% with the x-rays; a sensitivity of 57.6%, specificity of 29.6%, and accuracy of 51.4% with the ultrasound; and a sensitivity of 86.6%, specificity of 22.2%, and accuracy of 63.3% with magnetic resonance. CONCLUSIONS: X-rays showed specificitywhen the mirror sign was present. Magnetic resonance and ultrasound demonstrated themselves to be reliable methods with high accuracy for rotator cuff injury diagnosis.

            Rotator cuff tears: diagnostic performance of MR imaging.

            To determine the diagnostic performance of magnetic resonance (MR) imaging in the evaluation of suspected rotator cuff tears, eight asymptomatic volunteers and 32 patients with rotator cuff tendonopathy who underwent surgery were examined with MR imaging. Twenty-four of these patients also underwent contrast arthrography. The ability of MR imaging to depict the size of cuff tears and the quality of torn tendon edges was also evaluated. The MR imaging and arthrographic studies were reviewed without knowledge of surgical results or of the other studies. A scoring system was developed and a score assigned to each patient's MR study. The sensitivity of MR imaging for all tears (partial and full thickness) was 0.91, and the specificity was 0.88; whereas the sensitivity and specificity of arthrography were each 0.71. The scoring system improved the sensitivity to 1.0 and the specificity to 0.92. Linear regression analysis showed excellent correlation between preoperative assessment of the size of rotator cuff tears and measurement at surgery (r = .95).
