Musculoskeletal ultrasound is a commonly used surgical procedure to detect conditions such as musculoskeletal morphology and extent of injury. Musculoskeletal ultrasound mainly shows some structures and their lesions in our superficial soft tissues such as muscles, tendons, ligaments peripheral nerves. Musculoskeletal ultrasound reveals whether the muscles are atrophied or swollen. If there is an injury it can show the extent of the damage. It can also show whether the muscle is continuous or not, and if it is not, it is torn. With the continuous development of musculoskeletal ultrasound, the application of ultrasound-guided musculoskeletal interventional therapy has become more and more extensive, and it can be used for the treatment of calcific tendinopathy by puncture and crushing and suction therapy, the interventional therapy of periarthritis of the shoulder joint, and the treatment of intra-articular drug injection. Patients who have musculoskeletal injuries should go to the hospital in time and under the guidance of the doctor for relevant examinations.
