What are the common causes that trigger periarthritis? Below, we will discuss the common causes that trigger periarthritis. Generally, the common causes that trigger periarthritis include: 1. Soft tissue damage or degeneration around the shoulder joint: This can lead to supraspinatus tendonitis, biceps tendonitis, subacromial bursitis, joint capsule inflammation, and rotator cuff injury, ultimately leading to periarthritis. These chronic inflammations and injuries can all affect the joint capsule and surrounding soft tissues, causing chronic inflammation and adhesion in the joint capsule, which is one of the common causes that trigger periarthritis. 2. Acute trauma to the shoulder joint: This is also a common cause that triggers periarthritis, such as contusions of the shoulder, fractures of the surgical neck of the humerus, and dislocation of the shoulder joint. Due to inflammatory exudation, pain, and muscle spasm, office workers should be alert to periarthritis! This may lead to adhesion between the shoulder joint capsule and surrounding soft tissues, resulting in periarthritis. 3. Reduced function or prolonged fixation of the upper limb: Reduced shoulder activity leads to poor local blood circulation, obstructed lymphatic return, accumulation of inflammatory exudate, long-term fibrous deposition, and adhesion formation, leading to contracture of the joint capsule and adhesion of the surrounding soft tissues. Prolonged external fixation after shoulder dislocation, upper limb fracture, and surgery, or neglecting shoulder joint function exercises during fixation, may all be causes that trigger periarthritis. That's all about the introduction of the common causes that trigger periarthritis. I hope everyone has a better understanding now.
