Frozen shoulder or adhesive capsulitis is a disorder in which the capsule ( connective tissue surrounding the shoulder joint) becomes inflamed and stiff. The patient presents with restriction in shoulder movements and chronic pain. The symptoms can last up to 2 years or more without treatment. The exact cause of the condition is unknown but there is an association with diabetes, stroke and trauma/injury. Treatment involves anti-inflammatory medications, physiotherapy, manipulation under general anaesthesia and keyhole ( arthroscopic) release of the tight capsule.
