Labrum tears can be classified according to location and severity:

1. **Partial tear:** An incomplete tear where part of the labrum remains intact.

2. **Complete tear:** A complete tear where the labrum is detached from the socket.

3. **Traumatic tear:** Caused by sudden force, e.g., during a fall or impact.

4. **Degenerative tear:** Caused by chronic wear or age-related cartilage deterioration.

The main causes of labrum tears can be divided into several categories:

- Acute injuries:

- Direct impact, e.g., from a fall or trauma in contact sports.

- Overuse:

- Repetitive movements, e.g., in sports like tennis, swimming, or weightlifting, that stress the labrum.

- Degenerative changes:

- Age-related wear of the cartilage, making the labrum more susceptible to tears.

- Anatomical misalignments:

- Misalignments or deformities of the joint, such as hip dysplasia or an unstable shoulder, can promote a labrum tear.

- Dislocations:

- Repeated dislocations of the joint can lead to chronic damage and tears in the labrum.

The symptoms of a labrum tear depend on the location and extent of the damage:

• Pain: Localized pain that is exacerbated by certain movements, such as overhead work (shoulder) or rotational movements (hip).
• Movement restrictions: Difficulty moving the joint, especially when bearing loads or during rotations.
• Instability: A feeling of uncertainty or "giving way" in the joint.
• Grinding or snapping: An audible or palpable snapping in the joint during movement.
• Swelling: Slight swelling in the area of the affected joint.
• Loss of strength: Reduced muscle strength due to protective posture or pain.

The diagnosis is made through a combination of medical history, clinical examination, and imaging techniques:

• Medical History:
  • Collection of symptoms, accident details, and possible risk factors.
• Clinical Examination:
  • Special tests such as the O’Brien test (shoulder) or the FADIR test (hip) to identify labrum injuries.
• Imaging Techniques:
  • MRI: Visualization of the labrum and possible accompanying injuries.
  • CT Arthrography: Detailed examination of the labrum using a contrast agent.
  • X-ray: To rule out bony changes or accompanying injuries.

Conservative Therapy

In less severe cases, a labrum tear can be treated conservatively:

• Physiotherapy:
  • Exercises to strengthen the muscles and stabilize the affected joint.
• Medication Therapy:
  • NSAIDs to relieve pain and inflammation.
• Rest:
  • Reduction of strenuous activities to support healing.
• Injections:
  • Cortisone injections for pain relief and anti-inflammatory effects.

Surgical Therapy

In severe or non-conservatively treatable labrum tears, surgery is necessary:

• Arthroscopic Labrum Repair:
  • Minimally invasive reattachment of the labrum to the joint socket.
• Labrum Reconstruction:
  • Replacement of the damaged labrum with autologous or artificial tissue.
• Additional Stabilization:
  • Treatment of accompanying injuries, e.g., dislocations or joint instabilities.

To prevent labrum tears, the following measures are recommended:

1. Regular strengthening: Building muscle to stabilize the joint.
2. Technique training: Optimizing movement patterns to avoid incorrect loading.
3. Injury protection: Using appropriate protective gear in sports with a high risk of injury.
4. Adequate recovery: Observing breaks and recovery phases between intense activities.
5. Early detection: Seeking medical advice promptly at the first signs of discomfort to prevent major damage.
