What is Frozen Shoulder?
Description:
Adhesive capsulitis, commonly known as frozen shoulder, is a debilitating condition characterized by pain and limited shoulder mobility. This condition can significantly impact daily activities and quality of life. To effectively manage frozen shoulder, it's essential to understand its anatomy and how it develops.
Anatomy of Frozen Shoulder:
Frozen shoulder primarily affects the glenohumeral joint, where the upper arm bone (humerus) meets the shoulder blade (scapula). Key components include:
Shoulder Joint Capsule: A flexible yet tough connective tissue that surrounds the shoulder joint, keeping it stable.
Synovial Fluid: A lubricating fluid within the joint capsule that facilitates smooth shoulder movement.
Development of Frozen Shoulder:
Frozen shoulder typically progresses through three stages:
Freezing Stage: In this stage, patients experience increasing shoulder pain and a gradual loss of motion. The shoulder joint capsule thickens and tightens.
Frozen Stage: Pain may begin to diminish, but severe shoulder stiffness becomes more pronounced. Movements are significantly limited.
Thawing Stage: Gradually, the shoulder begins to regain motion. This stage can take several months to years.
Common Risk Factors:
Several factors may increase the risk of developing frozen shoulder:
Age: It is more common in individuals over 40, with the risk increasing with age.
Gender: Women are more likely to develop frozen shoulder.
Certain Health Conditions: Conditions like diabetes, heart disease, and thyroid disorders are associated with an increased risk.
Shoulder Trauma or Surgery: Injuries or surgeries involving the shoulder can trigger the condition.
Signs and Symptoms:
Common signs and symptoms of frozen shoulder include:
Pain: Often a dull or aching pain in the shoulder that worsens with movement.
Stiffness: Gradual loss of shoulder mobility, limiting range of motion.
Difficulty Sleeping: Pain and stiffness can make it challenging to sleep on the affected side.
