When a person falls in a lateral position, the palm of the hand lands on the ground and the torso tilts to one side, the shoulder joint is usually in the external booth, which can easily cause joint dislocation. Dislocation of the shoulder joint is often accompanied by a tear of the labrum, a fracture of the greater tuberosity of the humerus, a fracture of the surgical neck of the humerus, or a large fracture of the scapular glenoid. Some shoulder dislocations can become recurrent if they are not treated properly. (2) Open hand and fist exercise: open the palm of the hand with force and hold it for 2 seconds, then clench the fist to the maximum force, hold it for 2 seconds, relax and repeat, 5-10 minutes/hour after awake from anesthesia; (3) Triceps isometric contraction exercise: upper arm of the affected limb (3) Triceps isometric contraction exercise: isometric contraction exercise of the upper arm of the affected limb, can be performed with the assistance and protection of the healthy limb, 30 times/group, 3-4 groups/day; (4) Shoulder shrugging exercise: shrug the shoulder to the maximum force tolerated, hold for 2 seconds, relax and repeat, 30 times/group, 3-4 groups/day. (5) Active wrist flexion and extension exercises: move the wrist joint as widely as possible, 30 times/group, 3-4 groups/day; (6) About 3 days after surgery: start shoulder joint “swing exercises” according to the situation. “swing exercises”. Bend the body forward (stoop) until the upper body is parallel to the ground, and swing the arm under the protection of the triangular scarf and the healthy side hand. Start with the anterior-posterior direction, add the left and right lateral ones after getting used to the basic painlessness, and finally add the circular (rowing) movements, gradually increasing the range of motion, but not exceeding 90°, 20-30 times/group in each direction, 1-2 groups/day, and apply ice for 15-20 minutes immediately after the exercises; Postoperative weeks 2-3: Continue and strengthen the above exercises, gradually increasing the load and the angle of passive activity. Postoperative weeks 4-6: (1) Continue and intensify the above exercises, in which exercises that are completely painless and without fatigue can no longer be performed. (2) Biceps isometric exercises can be performed with the assistance and protection of the healthy limb, 30 times/group, 3-4 groups/day. Postoperative week 7 to 3 months: The main purpose of this stage is to gradually restore joint mobility. Exercises should be performed with full relaxation of the affected limb, without or with minimal pain, gently and slowly, and without violence. (1) Try to remove the protection of the triangular scarf 6-7 weeks after surgery; (2) Active shoulder strength exercises: front planks: lift the arm in front of the body to a pain-free angle, without shrugging the shoulder! Hold in the highest position for 2 minutes, rest for 5 seconds, 5 consecutive sets, 2-3 sets/day. Straighten the arm after the strength is increased. Side planks: Raise the arm to a pain-free angle on the side of the body without shrugging the shoulders! Hold in the highest position for 2 minutes, rest for 5 seconds, and perform 5 consecutive sets of 2-3 sets/day. Perform with straightened arms after strength building.
