Abstract Disorders of the ankle include both acute and chronic ruptures of tendons as well as a spectrum of chronic overuse injuries involving inflammatory and degenerative changes within the ligaments and surrounding tissues. Worldwide, the use of ultrasonography for the evaluation of the musculoskeletal system has been growing. Musculoskeletal ultrasonography is an important complementary tool to magnetic resonance imaging. Musculoskeletal ultrasound is a low-cost, noninvasive method of evaluating orthopedic trauma patients. It is particularly useful for patients with metallic hardware, which may degrade computed tomography or magnetic resonance images. Real-time dynamic ultrasonography examination allows identification of pathology and provides direct correlation between symptoms and the observed pathology. The development of high-frequency high-resolution modern electronic transducers has increased the possibility of ultrasonography in the detection of normal small anatomic structures and the assessment of a variety of musculoskeletal disorders. These improvements along with economic factors and availability have resulted in renewed interest in using ultrasound as a diagnostic tool. As such, the efficacy of ultrasound has been compared with other modalities, in particular MRI, as a cost effective imaging alternative. Ultrasound is an efficient and accurate imaging method for evaluation of tendon and ligament abnormalities. Like magnetic resonance imaging, ultrasonography is a technique that affords anatomic images in multiple planes and that may provide information about tissue characterisation. |
