The glenoid labrum plays a vital role in maintaining shoulder stability and ensuring smooth joint movement. Although it is a relatively small fibrocartilaginous structure, injuries to the labrum can significantly affect shoulder function, causing pain, instability, and reduced athletic performance.

Labral tears are common among athletes, individuals involved in repetitive overhead activities, and patients who experience shoulder dislocations or traumatic injuries. Thanks to advances in arthroscopic surgery, most labral injuries can now be repaired using minimally invasive techniques that restore joint stability while minimizing soft tissue damage.


What Is the Glenoid Labrum?

The glenoid labrum is a ring of fibrocartilage attached to the rim of the glenoid cavity. Its primary functions include:

  • Increasing the depth of the shoulder socket
  • Improving joint stability
  • Serving as an attachment site for ligaments and the long head of the biceps tendon
  • Distributing mechanical loads during shoulder movement

Although flexible, the labrum is susceptible to injury during trauma or repetitive stress.


Common Causes of Labral Tears

Labral injuries may result from several mechanisms, including:

  • Shoulder dislocation
  • Sports-related trauma
  • Repetitive overhead activities
  • Heavy lifting
  • Sudden traction injuries
  • Degenerative changes associated with aging

Athletes participating in baseball, volleyball, tennis, swimming, and contact sports are particularly at risk.


Types of Labral Tears

Bankart Lesions

Bankart lesions occur in the anterior-inferior portion of the labrum and are strongly associated with recurrent anterior shoulder instability.


SLAP Lesions

Superior Labrum Anterior to Posterior (SLAP) lesions involve the upper part of the labrum where the biceps tendon attaches.


Posterior Labral Tears

Less common than anterior injuries, posterior tears are frequently observed in athletes exposed to repetitive posterior loading.


Clinical Symptoms

Patients may experience:

  • Deep shoulder pain
  • Clicking or catching sensations
  • Shoulder instability
  • Weakness
  • Reduced range of motion
  • Difficulty performing overhead activities

Symptoms often worsen during sports or repetitive shoulder movements.


Diagnosis

Diagnosis combines clinical evaluation with imaging studies.

Healthcare professionals may use:

  • Patient history
  • Physical examination
  • Special instability tests
  • MRI or MR Arthrography
  • Diagnostic arthroscopy when necessary

Accurate diagnosis is essential for selecting the most appropriate treatment strategy.


Arthroscopic Repair

Arthroscopic labral repair has become the preferred treatment for many symptomatic labral tears.

During the procedure, the surgeon:

  • Visualizes the injured labrum
  • Prepares the glenoid surface
  • Places suture anchors
  • Reattaches the torn labrum
  • Restores shoulder stability

The minimally invasive nature of arthroscopy generally results in smaller incisions, reduced soft tissue disruption, and faster functional recovery compared with traditional open procedures.


Implants Used During Labral Repair

Modern arthroscopic repair commonly utilizes:

  • Soft Suture Anchors
  • Knotless Anchors
  • PEEK Anchors
  • Suture Passers
  • Arthroscopic Cannulas

The choice of implant depends on the location of the tear, bone quality, and surgeon preference.

Conclusion

Labral injuries are among the most common causes of shoulder pain and instability, particularly in active individuals and athletes.

Advances in arthroscopic repair techniques and modern fixation systems have significantly improved surgical outcomes, allowing many patients to return safely to daily activities and sports with restored shoulder stability.
