What causes a frozen shoulder?

There is currently no evidence as to the exact cause of adhesive capsulitis (frozen shoulder). It is a condition that can occur in people between 40 and 70 years of age, affects more women than men and  may occur after trauma, surgery or periods of shoulder immobilization. It can also affect people with certain comorbidities such as diabetes more severely. However the exact reason why an inflammatory condition starts in the capsule surrounding the joint is unknown and therefore there is no action that can be taken to prevent a frozen shoulder.
