Glenohumeral Joint Arthritis


 

A wearing out of the ‘ball and socket’ joint of the shoulder. Progressive cartilage wear leads to bone rubbing on bone.

 

Common Causes

Most cases have no obvious cause. There is probably a genetic predisposition. Occasionally there is a history of an old injury.

 

Symptoms

Increasing aching pain in the shoulder, radiating down the arm. Aggravated with activity or motion of the shoulder, and relieved with rest. Sleeping on the involved side is usually very uncomfortable. Patients may report a grinding sensation.

 

Physical Findings

Tenderness along the glenohumeral joint of the shoulder. Decreased range of motion, with pain at the extremes of motion.

 

Workup

Physical examination and special x-rays are diagnostic.

 

Non-operative Treatment

Anti-inflammatory medication may reduce symptoms. A well-placed corticosteroid injection can bring substantial relief to some patients, for a long time.

 

Surgical Treatment

Either a shoulder arthroscopy and debridement, or Total Shoulder Replacement.

 

Injury Comment

Most patients can be managed non-operatively. A shoulder arthroscopy is a straight forward outpatient procedure that only washes out the joint; it doesn’t replace the worn-out cartilage, and is of variable success. A shoulder replacement is a much more substantial procedure, but reliably improves pain relief and function.
