Bankart Lesion - Why Shoulder Keeps Slipping Out

If your shoulder keeps slipping out of place or feels unstable after an injury, it could be due to a condition known as a Bankart lesion. This is a common cause of recurrent shoulder dislocations, especially in young and active individuals.

Understanding what a Bankart lesion is and how it affects shoulder stability can help you identify the problem early and seek the right treatment.

What Is a Bankart Lesion?

A Bankart lesion is an injury to the labrum, the ring of cartilage that surrounds the socket of the shoulder joint. The labrum helps keep the head of the upper arm bone (humerus) securely in place.

When this cartilage is torn—usually due to a shoulder dislocation—the joint becomes unstable and more prone to slipping out again.

How Does It Occur?

A Bankart lesion typically occurs after a traumatic shoulder dislocation. When the shoulder pops out of its socket, it can tear the labrum from the front (anterior) part of the joint.

Common causes include:

• Sports injuries (especially contact sports)
• Falls on an outstretched arm
• Sudden forceful movements

Once the labrum is damaged, the shoulder loses its natural stability.

Why Does the Shoulder Keep Slipping Out?

The labrum acts as a stabilizing structure. When it is torn:

• The socket becomes less secure
• The humerus can move more freely than normal
• The risk of repeated dislocations increases

This is why individuals with a Bankart lesion often experience recurrent shoulder instability.

Symptoms of a Bankart Lesion

Common symptoms include:

• Repeated shoulder dislocations
• Feeling of looseness or instability
• Pain during movement
• Clicking or catching sensation
• Reduced strength in the shoulder

These symptoms may worsen over time if left untreated.

Who Is at Higher Risk?

People more likely to develop a Bankart lesion include:

• Young individuals and athletes
• Those involved in contact or overhead sports
• Individuals with a history of shoulder dislocation

Diagnosis

To confirm a Bankart lesion, a doctor may perform:

• Physical examination
• Shoulder stability tests
• MRI scan to assess labral damage
• X-rays to check for associated bone injuries

Accurate diagnosis is important for proper treatment planning.

Treatment Options

Non-Surgical Treatment

In mild cases or first-time dislocations, treatment may include:

• Rest and immobilization
• Pain management
• Physiotherapy to strengthen shoulder muscles

However, non-surgical treatment may not fully restore stability in all cases.

Surgical Treatment

Surgery is often recommended for recurrent dislocations or significant labral tears. The procedure involves repairing the torn labrum and restoring joint stability.

Arthroscopic surgery is commonly used for this condition.

Recovery and Rehabilitation

Recovery involves several stages:

• Immobilization for initial healing
• Gradual physiotherapy to restore movement
• Strengthening exercises for stability

Full recovery may take several months, depending on the severity of the injury.

What Happens If It Is Left Untreated?

Ignoring a Bankart lesion can lead to:

• Frequent shoulder dislocations
• Chronic instability
• Cartilage damage
• Early joint degeneration

Early treatment helps prevent these complications.

Can You Prevent It?

While not all injuries can be prevented, you can reduce risk by:

• Strengthening shoulder muscles
• Using proper techniques during sports
• Avoiding risky movements after an injury
• Completing rehabilitation programs fully

When Should You See a Doctor?

Consult a doctor if you experience:

• Repeated shoulder dislocations
• Persistent instability or looseness
• Pain during shoulder movement
• Clicking or catching sensations

Early diagnosis ensures better treatment outcomes.

Conclusion

A Bankart lesion is a common reason why the shoulder keeps slipping out after a dislocation. The damage to the labrum reduces joint stability, making recurrent dislocations more likely.

Recognizing the symptoms early and seeking appropriate treatment can help restore shoulder function and prevent long-term complications. Whether managed conservatively or surgically, proper rehabilitation is essential for recovery.

If your shoulder feels unstable or keeps dislocating, it is important to consult a specialist and address the issue before it worsens.
