A condition involving abnormal movement of the scapula

Snapping scapula syndrome is a condition characterized by a grinding or snapping sensation of the scapula (shoulder blade) as it moves along the rib cage. This condition can cause discomfort and pain in the shoulder region and is often associated with abnormal scapulothoracic motion.

Anatomy of the Scapula

The scapula is a flat, triangular bone located on the posterior side of the rib cage. It plays a crucial role in shoulder movement and stability. The scapula articulates with the humerus at the glenohumeral joint and with the clavicle at the acromioclavicular joint.

Causes

Snapping scapula syndrome can be caused by several factors, including:

• Bony abnormalities: Variations in the shape of the scapula or rib cage can lead to increased friction.
• Muscle imbalances: Weakness or tightness in the muscles surrounding the scapula, such as the serratus anterior or trapezius, can alter scapular motion.
• Inflammation: Inflammation of the bursae, which are fluid-filled sacs that reduce friction, can contribute to the syndrome.
• Injury: Trauma to the shoulder region can lead to changes in scapular movement.

Symptoms

The primary symptom of snapping scapula syndrome is a snapping or grinding sensation during shoulder movement. Other symptoms may include:

• Pain in the upper back or shoulder
• Limited range of motion
• Audible clicking or popping sounds

Diagnosis

Diagnosis of snapping scapula syndrome typically involves a physical examination and imaging studies. A healthcare provider may:

• Perform a physical exam to assess scapular movement and identify areas of tenderness.
• Use X-rays or MRI to visualize bony structures and soft tissues.
• Conduct a CT scan to evaluate the anatomy of the scapula and rib cage.

Treatment

Treatment for snapping scapula syndrome may include:

• Physical therapy: Exercises to strengthen and stretch the muscles around the scapula.
• Medication: Nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation.
• Injections: Corticosteroid injections to decrease inflammation in the bursa.
• Surgery: In severe cases, surgical intervention may be necessary to remove bony abnormalities or inflamed bursa.

Prevention

Preventive measures for snapping scapula syndrome focus on maintaining shoulder health and include:

• Regular exercise to strengthen shoulder muscles
• Proper posture to reduce strain on the shoulder
• Avoiding repetitive overhead activities that can stress the scapula
