Purpose: To estimate the accuracy of ultrasonography in detection of tendinous and ligamentous injuries around the ankle in comparison to MRI. Materials and methods: 60 patients referred with unilateral painful ankles are subjected to ankle ultrasonography and the results are compared with ankle MRI between December 2015 and September 2016. Results: 132 pathologies including 62 tendon lesions, 46 ligamentous lesions, 10 bursitis and 14 joint effusion were diagnosed by MRI. Ultrasonography detected 59 tendinous lesions (missed 3 partial tears) with allover accuracy of 96%, 41 ligamentous lesions (missed 1 stretching lesion, 2 partial tears and 1complete tear) with allover accuracy of 94.3%, all bursal lesions detected and 2 cases with joint effusion were missed by ultrasonography. Conclusion: Ultrasonography is an accurate and sensitive modality in detecting tendinous and ligamentous lesions around the ankle and represent with MRI complementary tool for diagnosis and can be used alone is some conditions Keywords: Ultrasonography of ankle, Ligaments, Tendons
