Snapping Scapula Syndrome SSS is a condition that causes a noticeable snapping or grinding sensation around the shoulder blade during movement. For people with Hypermobile Ehlers-Danlos Syndrome (HEDS), this syndrome can be particularly challenging. HEDS affects connective tissue, leading to joint hypermobility and instability, which can increase the risk of developing SSS. This post explores what Snapping Scapula Syndrome is, why it occurs in HEDS, and how it can be managed effectively.

Snapping Scapula Syndrome happens when the scapula (shoulder blade) moves abnormally against the rib cage. Normally, the scapula glides smoothly over the ribs, cushioned by muscles and bursae (fluid-filled sacs). In SSS, this smooth movement is disrupted, causing a snapping, grinding, or popping sound and sometimes pain.

People with SSS may feel discomfort during activities that involve raising the arm, reaching, or lifting. The snapping can be loud enough to hear without a stethoscope, and the pain may range from mild irritation to severe discomfort that limits daily activities.

Hypermobile Ehlers-Danlos Syndrome affects the body's connective tissues, including ligaments and tendons, making joints more flexible but also less stable. This instability can cause the scapula to move in unusual ways, increasing friction between the scapula and the ribs.

Several factors contribute to SSS in HEDS:

• Joint Hypermobility: Excessive movement of the shoulder blade can cause it to rub against the rib cage abnormally.

• Muscle Weakness: Weakness in the muscles that stabilize the scapula, such as the serratus anterior and trapezius, can lead to poor scapular control.

• Bursitis: Inflammation of the bursae between the scapula and ribs can worsen snapping and pain.

• Postural Issues: Poor posture, common in HEDS due to muscle fatigue and joint instability, can alter scapular positioning.

  
  

Recognizing Snapping Scapula Syndrome early can help manage symptoms before they worsen. Common signs include:

• A snapping or grinding sound when moving the shoulder blade

• Pain or tenderness around the upper back or shoulder blade

• A feeling of catching or popping during arm movement

• Reduced shoulder strength or range of motion

• Discomfort during activities like lifting, reaching, or overhead movements

  
  

If these symptoms appear, especially in someone with HEDS, it is important to seek evaluation from a healthcare professional familiar with connective tissue disorders.

Diagnosis usually starts with a detailed history and physical exam. The doctor will observe shoulder blade movement and listen for snapping sounds. Imaging tests such as X-rays, ultrasound, or MRI may be used to rule out other causes and assess soft tissue structures.

In HEDS patients, diagnosis can be more complex because joint hypermobility affects many areas. A multidisciplinary approach involving rheumatologists, physiatrists, or physical therapists experienced in HEDS is often helpful.

Treatment focuses on reducing pain, improving scapular stability, and restoring smooth movement. Options include:

Physical Therapy

Physical therapy is the cornerstone of managing SSS in HEDS. A tailored program may include:

• Strengthening exercises for scapular stabilizers like the serratus anterior and trapezius

• Stretching tight muscles around the shoulder and chest

• Postural training to improve alignment and reduce abnormal scapular motion

• Neuromuscular re-education to improve muscle coordination

  
  

Consistency with therapy is key, as muscle weakness and instability are ongoing challenges in HEDS.

Pain Management

Pain relief may involve:

• Over-the-counter pain medications such as acetaminophen or NSAIDs (nonsteroidal anti-inflammatory drugs)

• Ice or heat therapy to reduce inflammation and ease discomfort

• In some cases, corticosteroid injections near the scapula may be considered, but these should be used cautiously in HEDS due to tissue fragility

  
  

Activity Modification

Avoiding activities that trigger snapping or pain can help manage symptoms. This might mean:

• Limiting overhead lifting or repetitive shoulder movements

• Using ergonomic supports or braces to stabilize the shoulder during activity

• Incorporating rest periods to prevent muscle fatigue

  
  

Surgical Options

Surgery is rarely needed but may be considered if conservative treatments fail. Procedures aim to smooth the scapula’s undersurface or remove inflamed bursae. Surgery carries risks, especially in HEDS patients, so it is a last resort after thorough evaluation.

Managing SSS in the context of HEDS requires patience and a proactive approach. Here are practical tips:

• Work closely with healthcare providers who understand HEDS and its impact on joints.

• Commit to regular physical therapy and home exercises.

• Monitor symptoms and adjust activities to avoid flare-ups.

• Use supportive devices when needed to reduce strain on the shoulder.

• Educate yourself about HEDS and related musculoskeletal issues to advocate for your care.
