Labral Tears (Including SLAP Lesions)

What is the Labrum?
The labrum is a rim of cartilage around the shoulder socket (glenoid). It deepens the socket, stabilizes the shoulder, and serves as an anchor point for ligaments and the biceps tendon.
What is This Condition?
A labral tear is when this cartilage ring becomes frayed or detached.
A SLAP tear (Superior Labrum Anterior to Posterior) occurs at the top of the labrum, often where the biceps tendon attaches.
What Causes It?
Repetitive overhead throwing or lifting
Falls or sudden pulling injuries
Shoulder dislocations
Normal aging changes in the cartilage
What are the Symptoms?
Deep pain inside the shoulder, often with overhead activity
Catching, locking, or clicking sensations in the joint
Weakness or instability, sometimes described as the shoulder “slipping”
Pain with throwing or lifting
Decreased performance in sports, especially overhead or throwing athletes
How is It Diagnosed?
Physical exam: specific maneuvers that reproduce pain or clicking
MRI with contrast (arthrogram): shows tears in the labrum
Sometimes diagnosis is confirmed during arthroscopy
How is It Treated?
Rest and activity modification
Physical therapy to improve stability and mechanics
Anti-inflammatory medications
Cortisone injections for pain relief
Surgery if symptoms persist: arthroscopic labral repair, SLAP repair, or biceps tenodesis (releasing and reattaching the biceps tendon)
