Shoulder Labrum SLAP Tears (Posterior Labral Tears)

The glenoid labrum is a ring of fibrocartilaginous tissue that surrounds the glenoid cavity of the scapula (shoulder blade). It plays a crucial role in:

• Deepening the glenoid socket, enhancing the stability of the shoulder joint.
• Providing attachment points for the shoulder’s ligaments and the long head of the biceps tendon.
• Allowing smooth movement of the humeral head within the socket.

Posterior Labral Tears

• A posterior labral tear occurs in the back (posterior) portion of the labrum.
• These tears often result from repetitive stress, direct trauma, or posterior shoulder dislocation.
• Common in contact sports (e.g., football, wrestling) and activities involving overhead motion (e.g., weightlifting, baseball).

SLAP Tears

• A SLAP tear involves damage to the superior (top) part of the labrum, where the biceps tendon attaches.
• SLAP tears may result from acute trauma (e.g., falls, sudden pulling movements) or repetitive overhead motions (e.g., pitching, swimming, lifting).
• Common in overhead athletes and workers engaged in repetitive overhead lifting.

While symptoms vary, they often include:

• Pain in the back (posterior) or top of the shoulder
• Painful clicking, popping, or grinding sensations when moving the shoulder
• Weakness and a sensation of instability, making overhead or pushing movements difficult
• Decreased range of motion
• Pain with certain activities, such as throwing or lifting objects overhead
• Night pain or discomfort when lying on the affected shoulder

Many cases of labral tears can be managed conservatively without surgery. The primary nonsurgical treatment options include:

Rest and Activity Modification

• Avoid activities that aggravate symptoms, such as heavy lifting, overhead movements, or contact sports.

Physical Therapy (PT)

• Focuses on strengthening the rotator cuff and scapular muscles to improve shoulder stability.
• Stretching exercises to restore flexibility and range of motion.
• Proprioception and neuromuscular training to enhance coordination and prevent re-injury.

Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)

• Medications like ibuprofen or naproxen help reduce pain and inflammation.

Corticosteroid Injections

• May be used for short-term relief of pain and inflammation in moderate to severe cases.
• May be used to help augment progress with physical therapy.

If nonsurgical treatments fail and symptoms persist, surgical intervention may be necessary.

Arthroscopic Labral Repair

• For both posterior labral and SLAP tears, arthroscopic surgery is the preferred technique.
• Small incisions allow the insertion of a camera and specialized instruments to repair the torn labrum.
• Sutures and anchors are used to reattach the labrum to the glenoid

Biceps Tenodesis (For SLAP Tears)

• In cases where the biceps tendon is significantly involved, the tendon may be reattached to the humerus instead of the labrum to reduce stress on the shoulder.

Debridement (For Minor Tears)

• In cases of small or degenerative tears, commonly in older individuals, the damaged tissue is trimmed rather than fully repaired.
