Shoulder Labrum Tears: Causes, Symptoms, and Treatment

Our shoulders are two of the most mobile joints in our bodies that allow us to make a wide range of movements. However, because of this mobility, shoulders are also prone to instability that can result in a number of injuries. Among the various causes of shoulder pain and injuries are shoulder labrum tears. 

The labrum is a ring of cartilage in the shoulder joint, which plays a crucial role in providing stability and cushioning to the joint. When it gets damaged, it can lead to pain, instability, and limited movement, thereby impacting your quality of life.

Shoulder labrum tears are common among athletes, individuals performing repetitive overhead movements, or those who experience trauma to the shoulder. Understanding the causes, symptoms, and treatment options is key to effective recovery and preventing long-term issues. In this article, we explore what a shoulder labrum tear is, why it happens, and the steps you can take to regain full function and pain relief. 

What is the Shoulder Labrum?

The shoulder labrum is a ring of cartilage that surrounds the glenoid (the socket part of the shoulder joint). Its primary function is to:

• Provide stability to the shoulder by deepening the shoulder socket.
• Serve as an attachment point for ligaments and tendons.
• Cushion the joint to absorb shock and reduce wear.

When the labrum gets damaged because of an impact, wear and tear, or an accident, it can tear. This can result in instability, pain, and reduced range of motion.

Types of Shoulder Labrum Tears

There are several different types of labrum tears, depending on the location where the tear is. Understanding the type of tear is crucial to diagnose and treat it properly. The main types include:

SLAP Tears (Superior Labrum Anterior and Posterior)

SLAP tears are located at the top of the labrum, where it attaches to the biceps tendon. These tears usually occur when repetitive overhear activities such as throwing a ball and swimming are performed. Other common causes of SLAP tears include sudden trauma, like falling on an outstretched arm or lifting heavy objects with improper technique. These tears are common among athletes such as baseball pitchers, tennis players, and swimmers, as well as individuals with physically demanding jobs. The symptoms of a SLAP tear include:

• A catching or locking sensation in the shoulder.
• Pain during overhead movements or throwing.
• Weakness in the shoulder, particularly when lifting.

Bankart Lesions

Bankart lesions are the types of tears that are located on the lower-front portion of the labrum. The most common causes of bankart lesions are Shoulder dislocations, especially in young individuals and Traumatic injuries, such as a direct blow to the shoulder. Often, contact sport athletes (e.g., rugby, football) and individuals with a history of shoulder dislocations get these types of tears. Common symptoms include:

• A sensation of the shoulder "slipping out" of place.
• Chronic instability and recurrent shoulder dislocations.
• Pain during specific arm movements.

Posterior Labral Tears

Posterior labral tears affect the back part of the labrum. It is caused by repetitive posterior movements of the shoulder, for example, in the case of weightlifting or rowing. It can also be caused by trauma or impact to the shoulder including accidents, falls, or collisions. Typically, weightlifters, rowers, and athletes involved in sports with heavy pushing motions experience these tears. Common symptoms of a posterial labral tear include:

• Pain when pushing against resistance.
• Pain while doing bench presses.
• A feeling of instability or weakness in the back of the shoulder.

Combined Tears

Combined tears occur when the labrum is damaged at multiple locations. So, for example, an individual can have a SLAP tear and Bankart lesions at the same time. These combined tears typically occur as a result of severe trauma or high-impact injuries affecting the shoulder joint. They can also occur as a result of chronic instability that exacerbates damage to multiple areas. Individuals who delay treatment for initial tears can get combined tears as it can lead to built-up damage.

What Causes Shoulder Labrum Tears?

There are several factors that can contribute to labral tears:

• Trauma: Falls, car accidents, or sports injuries involving a sudden impact.
• Repetitive Overhead Movements: Common in sports like baseball, tennis, or swimming.
• Ageing: Wear and tear over time can weaken the labrum, increasing susceptibility to injury.

Symptoms of a Shoulder Labrum Tear

Although the symptoms of a shoulder labrum tear differ slightly according to the type and severity of tear, there are certain symptoms that can be generalised to all kinds of labral tears. Common signs include:

• Persistent shoulder pain, especially during specific movements.
• A catching, locking, or grinding sensation in the shoulder joint.
• Weakness or instability in the shoulder and arm, making it difficult to lift objects.
• Reduced range of motion in the shoulder.
• Shoulder pain during overhead activities or throwing motions.

Diagnosing Shoulder Labrum Tears

To diagnose a shoulder labrum tear, a sepcialised doctor may carry out different tests, that may include:

• Physical Examination:
  • Your doctor will assess shoulder movement, pain levels, and instability.
• Imaging Tests:
  • MRI with contrast: The doctor may order an MRI scan with contrast. This imaging test can reveal the extent of the tear and associated damage.
  • X-rays: Although an X-ray may not identify the damage to the labrum, it can help rule out other shoulder-related issues, such as fractures.

• Arthroscopy:
  • This is a minimally invasive procedure where a camera is inserted into the shoulder joint. The doctor may carry out this procedure for a detailed examination and to better visualise the shoulder labrum.

Treatment Options for Shoulder Labrum Tears

The shoulder labrum tears treatment in Singapore depends on the type, location, and severity of the tear. The level of your activity and overall health will also affect the kind of treatment. These treatments can include non-surgical as well as surgical options. 

Non-Surgical Treatments

Typically, the doctor recommends non-surgical treatments as the first line of management for minor labral tears or for patients who wish to avoid surgery. These can include:

• Rest and Activity Modification: This involves resting and avoiding activities that exacerbate symptoms.
• Physical Therapy: Physical therapy for shoulder labrum tears focuses on strengthening the shoulder muscles and improving stability.
• Anti-Inflammatory Medications: The doctor may prescribe anti-inflammatory medicines that help reduce pain and swelling.
• Injections: In some cases, the doctor may administer corticosteroid injections directly into the shoulder joint to provide temporary relief.

Surgical Treatments

If non-surgical methods fail or the tear is severe, your doctor may recommend surgery. THe surgery may involve the following procedures:

• Arthroscopic Surgery:
  • In this minimally invasive surgical procedure, a small camera is inserted through a small incision into the shoulder joint to visualise the area. Thin surgical instruments are also inserted through tiny incisions to carry out the procedure.
  • During the surgery, the surgeon may repair the damaged portion of the labrum or remove it using minimally invasive techniques.
• Labral Reconstruction:
  • This surgical procedure is carried out when the labrum cannot be repaired but must be replaced by a graft.
  • A graft from some other tendon in the body is used to replace severely damaged labral tissue.
• Biceps Tenodesis:
  • This procedure may be ordered if there is additional strain on the labrum that needs to be relieved.
  • In case of SLAP tears, the biceps tendon is relocated through this procedure to reduce strain on the labrum.

Recovery and Rehabilitation

Recovery after a shoulder labrum tear is a gradual process that requires patience, consistency, and adherence to a structured plan. Whether the shoulder labrum is treated surgically or non-surgically, the goal of rehabilitation is to restore strength, stability, and full range of motion while preventing re-injury. The timeline for recovery is discussed below:

Post-Surgery Recovery Timeline

• Immediately After Injury or Surgery, Weeks 1-4: The main focus during the initial weeks is on reducing pain and inflammation while protecting the shoulder with a sling.
• Early Recovery Phase, Weeks 5-8: During this phase, you will be advised to begin gentle range-of-motion exercises under a therapist’s guidance.
• Strengthening Phase, Weeks 9-16: Theis phase involves strengthening exercises to rebuild shoulder stability.
• Advanced Rehabilitation Phase, 4-6 Months: During the advanced rehabilitation phase, you can gradually return to normal activities and sports.

Key Tips for Recovery

• Follow your doctor’s and physiotherapist’s instructions diligently to avoid complications or re-injury.
• Stay Consistent as regular therapy sessions and home exercises are key to regaining function.
• Steer clear of overhead or heavy lifting motions until cleared by your doctor.
• Recovery takes time; avoid the temptation to rush back to activities prematurely.

Prevention Tips for Shoulder Labrum Tears

While not all shoulder labrum tears are preventable, you can reduce your risk by:

• Strengthening the muscles around the shoulder joint.
• Practising proper techniques during sports or workouts.
• Avoiding repetitive overhead motions when fatigued.
• Warming up before physical activities.

Conclusion

A shoulder labrum tear can be a painful and limiting injury, but with proper diagnosis and treatment, you can achieve full recovery. Whether through non-surgical interventions or surgery, addressing the issue promptly can prevent further complications and improve your quality of life.
