Ultrasonography is increasingly used in the diagnosis and treatment of musculoskeletal conditions and injuries. Ultrasonography possesses multiple advantages compared with other methods of imaging, including low cost, lack of radiation exposure, speed, and means for dynamic examination. Because of these advantages, many orthopaedic surgeons are routinely using ultrasonography to diagnose musculoskeletal conditions of the upper extremity. Musculoskeletal ultrasonography is technically challenging, but with proper guidance and practice, every orthopaedic surgeon can confidently integrate ultrasonography into their clinical practice.
