Is Your Shoulder 'Popping'? Discover the Mystery Behind Multidirectional Instability!
Published: Mar 22, 2024
Shoulder instability is a condition where the shoulder feels loose or dislocates in multiple directions. This article explores the causes, symptoms, and treatment of multidirectional instability (MDI) in the shoulder.

What Exactly is MDI?
MDI stands for multidirectional instability, and it's when the shoulder joint becomes lax in more than one direction. This condition can cause the shoulder to feel unstable and may lead to painful dislocations. Unlike simple laxity, which may not cause any issues, MDI is symptomatic and requires attention.
Who is Affected?
MDI is more common in young women and athletes under 40, particularly those engaging in repetitive overhead activities. While generalized joint laxity is common, MDI specifically affects the shoulder, causing issues during sports like swimming and gymnastics. It's also linked to congenital joint laxity or previous minor shoulder injuries.
Spotting the Symptoms
Symptoms of MDI can be vague, making it tricky to diagnose. Patients often report a loose or noisy shoulder, similar to rotator cuff problems. Symptoms tend to occur during shoulder movements and may include pain, weakness, or numbness, especially during specific activities like throwing or lifting.
Frequently Asked Questions
MDI can be caused by repetitive trauma or congenital joint laxity.
Young women and athletes under 40 are at higher risk.
MDI is symptomatic, causing pain and instability, unlike simple laxity.
Key Takeaways
