A friend asked me two days ago: I found that my shoulders on both sides of my shoulders are a little abnormal in the past two years. When I raise my hand or shrug my shoulders, it will "crack", but I don’t feel any pain, except for the sound. It's comfortable, and my shoulder hasn't suffered any injuries. What is going on? Serious?
"You may be snapping your shoulders. It's not a big problem. Just pay attention."
"Crack" on shoulder activity
Not many people have heard of the term snapping shoulders, but when it comes to "clicking" when the shoulder is moving, most people know what it is. In fact, snapping shoulder refers to the audible clicking or snapping of the shoulder joint during certain movements, but it is not an independent disease, but just a symptom.
Before understanding the snapping shoulder, we might as well understand the structure of the shoulder joint:
Shoulder structure
The shoulder joint plays a very important role in the human body, allowing the upper limbs to connect freely. The shoulder joint is mainly composed of the glenoid of the humeral head and scapula and the muscles attached to the joints. The humeral head is relatively large, while the glenoid is shallow and small. It is deepened by the surrounding fibrocartilage, and the contact area between the two is about 1/4 to 1/3 of the humeral head. Although this structural feature It allows the shoulder joint to perform various large-scale activities, but it also makes the joint prone to dislocation. Similarly, the shoulder joint capsule is relatively loose, and the long head tendon of the biceps brachii muscle passes through it. Although the shoulder joint has a rich muscle covering, the front and lower parts lack the protection of muscles and tendons and are relatively weak. Therefore, the common dislocation of the shoulder joint is mainly the front and lower dislocation.
So how did the snapping shoulder appear?
- There are two main reasons for the snapping shoulders:
Shoulder
1. Subluxation of the shoulder joint occurs during movement. In most patients with snapping shoulders, 80% of them are related to shoulder subluxation. The shoulder joint is the most flexible joint of the human body. It can move in all directions, and the range of motion is relatively large. This is mainly related to the shallow glenoid of the shoulder joint, the small joint contact area, and the thin and loose joint capsule. When a large amount of exercise occurs, if part of the shoulder joint muscles is unstable or the tendons are relatively weak, subluxation is prone to occur. Often these subluxations are temporary, and the joint can reset itself when the movement continues. At this time, the joint bones and bones or cartilage There was a bounce due to collision and friction. It is worth noting that once this kind of buzzing is formed, most of it will always be accompanied, and it may become a habit.
2. It is related to abnormal tissue strands in or around the shoulder joint. When there are abnormal tissue strands in or around the shoulder joint, such as ectopic muscles and tendons, abnormal muscles, etc., when the shoulder joint is active, the bony process slips up and collides with these abnormal tissue strands to produce bounce.
In fact, in addition to snapping the shoulders, snapping the shoulder blades can also cause a "crack" sound when the shoulder is moving.
In fact, in addition to snapping shoulders, snapping shoulder blades are also one of the things that can cause a "click" sound when the shoulders are moving. Similar to snapping shoulders, snapping shoulder blades refer to the audible snapping sound of the shoulder blades during movement. The scapula resembles a triangle, covering the upper part of the chest and back of a person. The glenoid at the outer corner of the scapula participates in the formation of the shoulder joint, which is mainly supported by the shoulder joint and acromioclavicular joint.
shoulder blade
- The reason for the formation of snapping shoulder blades is mainly related to the following three points:
1. Abnormal structure of the scapula. Generally, it is an abnormal curvature of the upper scapula, and exostoses on the deep side of the scapula.
2. Abnormal ribs. The scapula mainly covers the upper part of the chest and back and is closely connected to the thoracic section of the ribs. When the ribs are abnormal, such as rib fractures, bends, angulations, or rib tumors, the scapula movement will have contact friction and produce bounce.
3. Muscle disease or bursitis. During the movement of the scapula, the scapular joint muscle pathology can cause the appearance of snapping. At the same time, there are three bursae on the deep surface of the scapula, one is the deep surface of the serratus anterior muscle, and the other is the connective connection between the serratus anterior muscle and the upper chest wall Between the tissues, in addition, additional bursae may appear at the subscapular corner.
What should I do when there is a buzzing sound in shoulder activity?
According to the above two symptoms, X-ray examination of the shoulder joint is generally sufficient. However, if there are tissue diseases such as muscles and tendons, magnetic resonance examination can be used to further confirm the condition.
X-ray inspection
It is worth noting that the above snapping shoulder and snapping scapula only show the snapping sound when the shoulder is moving, and it is often not accompanied by discomfort such as pain and movement disorders. If there are related symptoms, further examination and treatment should be done.
Is there a serious buzz from shoulder movement? What should I pay attention to when there is a sound?
In fact, snapping sound in shoulder activities is a very common symptom. Whether it is snapping shoulders or snapping shoulder blades, based on the reasons for their formation, they generally do not pose a big threat to human health, but if the shoulder snaps If the condition lasts for a long time and causes local pain and discomfort, you should seek medical attention in time to rule out joint snapping caused by other reasons.
Shoulder muscles exercise
At the same time, we can also strengthen the exercise of the shoulder muscles in our daily life to make the joints more stable, which can reduce the sound of shoulder activities. However, the elderly also need to pay attention to avoid large-scale movements of the shoulders, minimize the weight of the upper limbs and lift heavy objects, and protect the joints of the shoulders.
