This document discusses the management of shoulder stiffness from various causes such as adhesive capsulitis and postoperative stiffness. Adhesive capsulitis is characterized by fibroblastic proliferation in the shoulder capsule similar to Dupuytren's contracture. Risk factors include diabetes. Non-operative management includes physiotherapy, steroid injections, hydrodilation, and nerve blocks, with hydrodilation providing relief in 75% of cases. For postoperative stiffness, the majority can be treated non-operatively but some may require manipulation under anesthesia or arthroscopic capsular release. Post-operative physical therapy is important for recovery.
