The acromioclavicular joint is one of the most flexible joints in the human body, located in the shoulder, connecting the sternum and collarbone. It acts as a stabilizing part of the shoulders and allows us to perform various movements such as lifting, spinning, and swinging. This article will detail the anatomy, function, and common problems of the acromioclavicular joint.
The acromioclavicular joint is made up of the junction between the scapula and the clavicle, forming a powerful pivot. This structure allows the acromioclavicular joint to have excellent mobility and absorb the impact forces from the upper limbs. In addition, the acromioclavicular joint maintains the stability of the shoulder, allowing us to balance the weight of the upper limbs.
One of the main functions of the acromioclavicular joint is to lift and rotate the upper limbs. Whether it's throwing a ball, swinging a racket, or carrying a heavy object, the acromioclavicular joint is subjected to tremendous force from the upper limbs. At the same time, the acromioclavicular joint is also able to control the posture and orientation of the upper limbs, allowing us to perform various movements accurately.
However, due to the complex structure of the acromioclavicular joint and the high-intensity exercise that is often performed, it is also prone to injury or problems. The most common problem with the acromioclavicular joint is a dislocation of the acromioclavicular joint. When the force outside the joint exceeds its capacity, the joint dislocations, resulting in an unstable connection between the scapula and clavicle. Dislocations can occur anteriorly, posteriorly, or below, causing different symptoms and effects.
Another common acromioclavicular joint problem is acromial fractures. The acromial bone is part of the acromioclavicular joint and is located between the sternum and clavicle. When a fracture occurs, the acromial bone may break or displace, leading to joint instability and pain.
Inflammation of the acromioclavicular joint is also a common problem, especially after overuse or injury. Shoulder arthritis often causes joint pain, swelling, and functional limitations, and in severe cases, can affect the quality of daily life.
In order to protect the health of the acromioclavicular joint, there are a few things we can do. First and foremost, proper posture and posture are key to maintaining the stability of the acromioclavicular joint. Maintain a correct posture of sitting, standing and walking, pay attention to the relaxation and stretching of the shoulders, and avoid being fixed in one position for long periods of time.
Secondly, exercise the shoulder muscles reasonably. By doing regular strength training and stretching exercises in the shoulders, you can increase the stability of your joints and reduce tension and stress on your muscles.
Finally, seek medical help if necessary. If you experience pain, swelling or joint instability in your shoulder during activity, consult your doctor for an accurate diagnosis and advice. Don't ignore these issues before they lead to more serious consequences.
In summary, the acromioclavicular joint is an important joint for us to perform various upper limb exercises. Understanding the anatomy and function of the acromioclavicular joint, and how to protect its health, is essential to maintaining the stability and function of the shoulder. With proper posture, exercise, and necessary medical intervention, we can reduce the occurrence of acromioclavicular joint problems and ensure the normal movement and function of the shoulder.
