Department, Faculty of Medicine, Cairo University, Egypt, [email protected]. Abstract Ankle pain is a common complaint in orthopedic practice. Various imaging techniques are available for assessment of ankle joint abnormalities. However, many ankle injuries were undiagnosed by conventional radiology and needs further evaluation to diagnose ligamentous, tendinous and muscle injuries as well as osseous lesions as stress fractures, osteochondral lesions, and avascular necrosis. The aim of this study was to compare the diagnostic accuracy of both ultrasonography (US) and magnetic resonance imaging (MRI) for the assessment of pain around the ankle in different musculoskeletal disorders. Ultrasonography and MRI are two complementary tools of investigation with the former being used as primary tool of investigation and the latter is done to confirm the diagnosis and the extent of the lesion especially when surgical interference is planned. Keywords: Ankle pain, Musculoskeletal disorders, Ultrasonography, MRI. Introduction The ankle is a “hinged” joint capable of moving the is surrounded by a fibrous joint capsule. The tendons foot in two primary directions: away from the body attach the muscles of the leg to the foot wrap around the ankle both from the front and behind. A large tendon (Achilles tendon) passes behind the ankle (plantar flexion) and toward the body (dorsiflexion). and attaches at the back of the heel. The posterior It is formed by the meeting of three bones. The end of tibial tendon passes behind the medial malleolus. The both the tibia and the fibula meet the talus, to form the to attach into the foot (2). peroneal tendon passes behind the lateral malleolus ankle. The end of the tibia forms the medial portion The normal ankle joint is capable of moving the foot eof the ankle, while the end of the fibula forms the lateral portion of the ankle.
