Snapping Scapula Syndrome
What is Snapping Scapula Syndrome?
Snapping scapula syndrome is a condition where abnormal contact between the scapula and rib cage causes a snapping, popping, or grinding sensation during shoulder movement.
- Snapping or grating in the scapular region
- May cause pain and dysfunction
Overview of the Condition
Contributing factors include scapular dyskinesis, bursitis under the scapula, or bony abnormalities of the scapula or ribs.
Symptoms
- Audible clicking or snapping with shoulder motion
- Localized pain around the scapula
- Possible scapular winging or dyskinesis
Causes
Abnormal scapulothoracic articulation due to muscular imbalances, scapular bursitis, or bony protrusions can cause friction and snapping.
Diagnosis
Clinical exam focusing on scapular motion. Imaging (MRI or ultrasound) may identify bursitis or bony anomalies. Dynamic scapular evaluation helps confirm diagnosis.
Treatment Options
- Physical therapy for scapular stabilization
- NSAIDs or injections for inflammation
- Surgery (bony resection or bursectomy) if conservative care fails
Conservative Management
Emphasis on correcting scapular dyskinesis through exercises targeting serratus anterior and lower trapezius. Anti-inflammatories reduce pain.
Rehabilitation Exercises
- Scapular retraction and protraction drills
- Serratus punch exercises
- Postural correction and thoracic mobility exercises
Surgical Options
Arthroscopic or open procedures may remove bony prominences or inflamed bursae to alleviate snapping.
Anatomy Overview
The scapulothoracic articulation relies on smooth gliding between the scapula and rib cage. Any irregularity can cause friction.
Affected Areas
- Scapulothoracic bursa
- Scapular underside, rib cage surface
Frequently Asked Questions
| Question | Answer |
|---|---|
| Does snapping scapula always require surgery? | Most cases improve with physical therapy and conservative measures; surgery is last resort. |
| Is snapping scapula dangerous? | It can cause pain and functional limitations but usually is not dangerous if managed properly. |
Prevention Strategies
- Maintain balanced shoulder and scapular muscle strength
- Avoid repetitive overhead activities if causing discomfort
- Practice proper posture
