Adhesive capsulitis, commonly known as frozen shoulder, is a painful disorder that causes the shoulder joint to become very rigid. One kind is primary (idiopathic), while the other is secondary (caused by something else, such as trauma, surgery, or being immobile) that is related to inflammation. The incidence rates may be approximately 20% in people with diabetes, far greater than the general population frequency of 2-5%. Limitations in shoulder mobility are the result of an inflammatory process that starts within the joint capsule and progresses to fibrosis and adhesion development. When there are no significant radiological abnormalities and the patient experiences a gradual decrease in active and passive shoulder mobility, a clinical diagnosis is usually made. In most instances, the disease's symptoms will go away after a while, but in others, they may linger for years. Ultrasound and magnetic resonance imaging (MRI) may aid in the diagnosis of more complicated situations. Treatment options include non-invasive methods such as physiotherapy, NSAIDs, and injections of steroid medication into the affected joint. Surgical procedures, including capsular release or manipulation while under anesthesia, may be necessary for more serious or long-lasting instances. Although adhesive capsulitis usually resolves on its own, untreated symptoms might cause impairment in the long run.
