SHOULDER LABRAL TEAR

The labrum is a ring of cartilage located around the socket of the shoulder joint. The shoulder is a ball-and-socket joint, and the labrum plays a vital role in stabilizing the shoulder and keeping the ball of the upper arm securely positioned within the socket.

Unlike smooth articular cartilage, the labrum is firmer and more rigid. It serves two important functions:

• Stabilizing the shoulder joint by deepening the socket and acting as a protective bumper.
• Providing attachment points for ligaments and surrounding soft tissues that support shoulder stability.

When the labrum becomes torn due to injury or shoulder dislocation, the shoulder may become unstable, leading to pain, weakness, subluxation, or complete dislocation.

Why do labral tears occur?

• Partial shoulder dislocation (subluxation)
• Complete shoulder dislocation
• Traumatic shoulder injury
• Repetitive overhead movements
• Sports-related injuries

The shoulder may dislocate toward the front (anterior dislocation) or toward the back (posterior dislocation).

What are the common symptoms of a shoulder labral tear?

• Shoulder pain – Sharp or deep pain within the shoulder joint.
• Clicking, popping, or grinding sensations – Noises during shoulder movement.
• Shoulder instability – A feeling that the shoulder may slip out of place.
• Reduced range of motion – Difficulty moving the shoulder freely.
• Weakness in the shoulder or arm – Reduced strength during lifting or reaching.
• Pain during overhead activities – Discomfort when throwing, lifting, or reaching overhead.
• Locking or catching sensation – The shoulder may feel stuck during movement.
• Pain that worsens with activity – Symptoms may increase during exercise or repetitive movements.
• Difficulty sleeping on the affected shoulder
• Sudden sharp pain with certain movements

Treatment for Shoulder Labral Tears

Treatment varies depending on the type of labral tear. Tears caused by instability from subluxation or dislocation often require the labrum to be reattached to the rim of the socket. This procedure can be performed arthroscopically, using small incisions, or through an open incision at the front of the shoulder. Arthroscopic shoulder surgery offers significant advantages, allowing surgeons to operate in confined spaces with high precision. Additionally, this minimally invasive approach typically results in faster recovery, fewer postoperative complications, and reduced pain.

Recovery from Surgery

Full recovery depends on several factors, including the location and severity of the tear and the success of the surgical procedure. Strict adherence to all postoperative care guidelines is essential to promote a smooth and uncomplicated recovery.
