SLAP tear (Superior Labrum Anterior and Posterior)

What is a SLAP tear?

The labrum is a ring of cartilage around the shoulder socket that helps deepen the socket and improve stability. A SLAP tear affects the superior part of this cartilage ring, near the biceps tendon attachment.

Not all labral tears are the same. A SLAP tear is one specific pattern, and the best treatment depends on tear type, symptoms, and your activity demands.

Causes of SLAP tear

A SLAP tear can develop from injury or repetitive stress. Common causes include:

1. Falling onto an outstretched arm
   
2. A sudden traction injury, such as trying to catch a heavy object
   
3. Repetitive overhead activity, including throwing sports and some gym movements
   

In overhead athletes, the mechanics of throwing can stress the superior labrum and contribute to a slap tear shoulder problem over time.

Symptoms of a SLAP tear shoulder injury

Symptoms vary, but common features include:

• Deep shoulder pain, often worse with overhead activity
  
• Clicking, popping, catching, or a “locking” sensation
  
• Pain with certain positions, including behind-the-head or “cocking” positions for throwing
  
• A feeling of weakness or reduced power, especially during sport or lifting
  

A key point is that a slap tear shoulder injury can feel “inside the joint” rather than superficial muscle soreness.

When to seek assessment

Consider an earlier review if you have:

• Persistent pain for more than a few weeks
  
• Repeated catching or painful clicking
  
• Symptoms that limit work, training, or sleep
  
• Ongoing pain despite rest and simple measures
  

These do not always mean you need slap tear surgery, but they are good reasons to confirm the diagnosis and rule out associated issues, such as rotator cuff irritation or shoulder instability.

Diagnosis of Shoulder SLAP Tear

Diagnosis begins with history and a shoulder examination, including tests that load the labrum and biceps anchor.

Imaging may be recommended, such as:

• X-rays to assess bony anatomy and rule out other causes of pain
  
• MRI (sometimes MR arthrogram) to evaluate the labrum and biceps anchor
  
• In some cases, arthroscopy is used to confirm and treat the tear
  

Because several shoulder conditions overlap, imaging helps clarify whether symptoms are from a SLAP tear or another source.

Treatment for SLAP tear

Treatment is guided by: tear type, symptom severity, age, sport demands, and associated shoulder problems.

Non-surgical treatment

Many SLAP tears improve with a structured plan, especially when the main issue is pain rather than true mechanical locking. Non-surgical care may include:

• Activity modification, particularly reducing provocative overhead actions temporarily
  
• Anti-inflammatory medication when appropriate
  
• Physiotherapy focused on shoulder blade control, rotator cuff strength, range of motion, and gradual return to activity
  

For many people with a slap tear shoulder diagnosis, good rehabilitation is the turning point.

When is slap tear surgery considered?

Slap tear surgery may be discussed when:

• Symptoms persist despite a proper rehabilitation programme
  
• There is ongoing painful catching or functional limitation
  
• You need reliable overhead performance for work or sport
  
• The tear pattern and clinical findings suggest that surgery is likely to improve stability and function
  

Not every SLAP tear benefits from the same operation. The surgical plan should match your age, activity demands, biceps involvement, and tear type.

Slap tear surgery options

Most procedures are performed arthroscopically, using keyhole incisions. Options may include:

1. SLAP repair, where the labrum is reattached to the socket using suture anchors
   
2. Debridement, where frayed tissue is smoothed in selected cases
   
3. Biceps tenodesis, where the biceps tendon attachment is moved away from the superior labrum to reduce traction and pain, used in selected patients
   

Your surgeon will explain the most suitable option based on the tear pattern and your goals. The aim of slap tear surgery is to reduce pain, restore function, and allow a safe return to activity.

Recovery and rehabilitation

Rehabilitation is essential after both non-surgical care and slap tear surgery.

After surgical treatment, recovery can take several months and may be longer for overhead athletes.
Typical rehab progresses through phases: protected movement, gradual active motion, strengthening, then sport or work-specific training.
