Slap Tear
A SLAP Tear (Superior Labrum Anterior to Posterior tear) is a type of shoulder injury that affects the Glenoid Labrum, a ring of cartilage surrounding the shoulder socket. The tear occurs at the top (superior) part of the labrum, where the Biceps Tendon attaches.
The labrum helps stabilize the shoulder joint by deepening the socket of the Scapula and keeping the head of the Humerus securely in place.
A SLAP tear can lead to shoulder pain, instability, weakness, and limited range of motion, especially during overhead activities.

What is Slap Tear
A SLAP Tear (Superior Labrum Anterior to Posterior tear) is a type of shoulder injury that affects the Glenoid Labrum, a ring of cartilage surrounding the shoulder socket. The tear occurs at the top (superior) part of the labrum, where the Biceps Tendon attaches.

Types of Slap Tear
- Type I SLAP Tear
- Type II SLAP Tear
- Type III SLAP Tear
- Type IV SLAP Tear
Type I SLAP Tear
A Type I SLAP Tear involves fraying of the superior labrum without detachment.
Characteristics
- Labrum shows wear and fraying
- Biceps tendon attachment remains stable
- Often associated with aging
- Usually treated without surgery
Type II SLAP Tear
A Type II SLAP Tear is the most common type of SLAP injury.
Characteristics
- The superior labrum is detached from the glenoid socket
- The biceps tendon anchor becomes unstable
- Causes pain and shoulder instability
Treatment
- Often requires Arthroscopic Shoulder Surgery.
Type III SLAP Tear
A Type III SLAP Tear involves a bucket-handle tear of the labrum.
Characteristics
- Torn fragment of labrum hangs into the joint
- Biceps tendon remains intact
- May cause catching or locking in the shoulder
Type IV SLAP Tear
A Type IV SLAP Tear is a more severe injury.
Characteristics
- Bucket-handle tear extends into the biceps tendon
- Both the labrum and tendon are damaged
- Often requires surgical repair
Common Causes of SLAP Tears
SLAP tears can occur due to trauma or repetitive shoulder use.
1. Acute Injury
- Falling on an outstretched arm
- Shoulder dislocation
- Sudden pulling injury
- Car accidents or sports injuries
2. Repetitive Overhead Activity
- Throwing sports (cricket, baseball)
- Swimming
- Tennis
- Weightlifting
3. Age-Related Degeneration
As people age, the labrum becomes weaker and more prone to tearing.
Symptoms of SLAP Tear
Patients with a SLAP tear may experience:
- Deep shoulder pain
- Clicking or popping sensation in the shoulder
- Shoulder weakness
- Difficulty lifting objects
- Pain during overhead movements
- Reduced range of motion
- Feeling of shoulder instability
Diagnosis
Doctors diagnose SLAP tears using clinical examination and imaging tests.
1. Physical Examination
Orthopedic specialists perform tests such as:
- O’Brien’s Test
- Speed’s Test
- Crank Test
These help evaluate labral injury and shoulder stability.
2. Imaging Tests
- X-ray – Used to rule out bone injuries
- Magnetic Resonance Imaging (MRI) – Helps detect labral tears
- MR Arthrography – Highly accurate for diagnosing SLAP lesions
Surgical Treatment
Surgery may be recommended when symptoms persist.
Common Procedures
1. Arthroscopic Labral Repair
The torn labrum is reattached to the bone using anchors.
2. Biceps Tenodesis
The biceps tendon is reattached to a different location to relieve stress on the labrum.
3. Labral Debridement
Damaged tissue is trimmed to smooth the joint surface.
Complications if Untreated
If a SLAP tear is not treated properly, it may lead to:
- Chronic shoulder pain
- Shoulder instability
- Reduced arm strength
- Limited shoulder mobility
- Increased risk of Shoulder Impingement Syndrome
Prevention Tips
To reduce the risk of SLAP tears:
- Perform shoulder strengthening exercises
- Warm up before sports activities
- Avoid repetitive overhead strain
- Maintain proper lifting techniques
- Improve shoulder flexibility and posture
Summary
A SLAP tear is an injury to the superior portion of the shoulder labrum where the biceps tendon attaches. It is commonly seen in athletes and individuals performing repetitive overhead activities. Early diagnosis and appropriate treatment help restore shoulder stability and function.
