Since the 80 s ultrasound was first used to examine rotator cuff injuries, ultrasound has been currently applied to a variety of shoulder joint disease examinations as clinical experience has accumulated and instrument performance has improved.
Different body positions are needed to be arranged during shoulder joint examination, a patient can sit on a chair without a backrest during the examination, and the shoulder joint examination can be started from the tendon of the long head of the biceps brachii. The patient puts the hand on the knee, and the palm is upwards, and the probe crosscut is placed in the intertubercle ditch, and after the transverse section was swept and is looked into, the probe rotated 90 degrees rip cutting and is looked into the tendon, can show muscle tendon junction downwards, and this is the lowest position in articular cavity when standing the position, can show at this tangent plane when articular cavity hydrops is less. The patient is then asked to place the back of the hand to pronate and extend the shoulder joint, allowing the supraspinatus tendon to slide out from under the acromion and to be in a stressed position to aid in the detection of minor tears in the tendon. The supination of the upper arm may well show the subscapularis. The patient is then allowed to relax his upper limbs and place on the contralateral shoulder to examine the infraspinatus and teres minor, which may also be used to examine the posterior glenoid labrum. Finally, the arm is abducted, and the thickness of the infraarticular fold of the shoulder is examined, which is an important index for diagnosing the adhesive arthritis.
