Shoulder Conditions - Shoulder Impingement Syndrome

Shoulder impingement syndrome occurs when the tendons of the rotator cuff, along with the subacromial bursa, become compressed against a bony scapula protrusion called the acromion. As these tissues continually rub against the bone, they become irritated and inflamed causing tenderness, swelling, reduced range of motion, and weakness in the shoulder. Minor pain may be present even when the shoulder is at rest, while sudden, sharp pain may be felt when the arm is used.

This condition is typically caused by excessive use of the shoulder or repetitive overhead motions. Treatment options include rest, anti-inflammatory medications, cortisone injections, and physical therapy. In severe cases, surgery may be needed to create more space above the rotator cuff (subacromial decompression).
