Shoulder impingement, also known as subacromial impingement, is a common condition that occurs when the tendons or bursa (fluid-filled sacs) in the shoulder become compressed or pinched between the bones of the shoulder joint. The shoulder joint is a complex structure that consists of the humerus (upper arm bone), the scapula (shoulder blade), and the clavicle (collarbone). It also includes several muscles, tendons, and ligaments that help stabilize and move the shoulder.
Shoulder impingement typically involves the tendons of the rotator cuff, a group of muscles and their associated tendons that help with the rotation and movement of the shoulder. The rotator cuff tendons pass through a narrow space beneath the acromion, a bony projection of the scapula, and the coracoacromial ligament. When this space narrows or becomes compromised, it can lead to compression and irritation of the tendons and bursa, causing pain and inflammation. This condition is often associated with repetitive overhead arm movements, such as those performed in sports like swimming, tennis, or baseball, or in activities like painting or carpentry.
Symptoms of shoulder impingement may include:
Treatment for shoulder impingement may include:
It's important to consult us or another healthcare professional for a proper diagnosis and treatment plan if you suspect you have shoulder impingement, as this condition can worsen if left untreated. Early intervention and appropriate rehabilitation can help alleviate pain and restore function to the shoulder.
