Shoulder Joint

Shoulder arthritis, characterized by inflammation within the shoulder joint, leads to cartilage deterioration over time. This condition primarily affects the glenohumeral joint, a pivotal “ball and socket” structure where the upper arm bone (humerus) connects with the shoulder blade (scapula). It can also occur at the acromioclavicular joint (AC joint), where the collarbone meets the shoulder blade. Symptoms of shoulder arthritis include pain, stiffness, decreased range of motion, and audible popping or grinding sensations within the joint. Risk factors include age, with individuals over 50 being more susceptible, as well as conditions like rheumatoid arthritis and shoulder trauma. Complications may include difficulty performing daily tasks and disrupted sleep due to discomfort. Treatment options range from nonoperative approaches such as exercises and lifestyle adjustments to medication and surgical interventions. Medications like acetaminophen or NSAIDs can alleviate pain and inflammation, while corticosteroid injections offer temporary relief. Surgical procedures, including total shoulder replacement or arthroscopic debridement, may be necessary for severe cases resistant to conservative treatments. While there is no cure for shoulder arthritis, effective management strategies can significantly improve symptoms and enhance quality of life.
