What common condition is referred to as "frozen shoulder"?

The term "frozen shoulder" specifically describes a condition known as adhesive capsulitis. This condition involves the thickening and tightening of the shoulder capsule, leading to pain and severely restricted motion. Patients with frozen shoulder often experience stiffness and discomfort, making it difficult to perform everyday activities that involve shoulder movement.

Adhesive capsulitis typically develops gradually and can be associated with various factors, such as previous shoulder injuries or surgical procedures, and it may take several months to resolve. The condition often progresses through stages, starting with pain, followed by stiffness, and ultimately returning to increased range of motion, albeit sometimes with residual issues.

While arthritis, sciatica, and osteoarthritis are related to joint and musculoskeletal issues, they do not specifically describe the condition characterized by the stiffness and limited motion of the shoulder that is associated with frozen shoulder. Hence, the appropriate identification of "frozen shoulder" as adhesive capsulitis highlights its unique clinical features and underscores the importance of accurate terminology in medical coding and diagnosis.
