What is adhesive capsulitis?

Adhesive periarthritis is a condition in which the soft tissues inside the shoulder joint become adherent, resulting in symptoms of limited shoulder movement. Frozen shoulder, also known as periarthritis of the shoulder, occurs in women around the age of 50. When adhesions of muscles, tendons, synovium and other parts of the shoulder occur, it is called adhesive periarthritis, also known as frozen shoulder. Adhesive frozen shoulder is mainly characterized by limited movement of the shoulder joint and widespread pain, and some patients may experience atrophy of the muscles around the shoulder joint due to the pain. The cause of adhesive capsulitis is mainly due to the increase of sterile inflammatory exudation and the decrease of shoulder joint movement. The increase of sterile inflammation exudation can lead to adhesion of the joint capsule in the shoulder joint, tissue edema, and local blood circulation disorder, which affects the normal function of the joint; most of the patients may reduce the activity of the shoulder joint due to pain, which aggravates the adhesion of the joint. If adhesive capsulitis is diagnosed, early and standardized treatment is recommended to reduce the adverse effects of the disease.
