Shoulder Labrum Tear: Symptoms, Causes, & Relief

Your shoulder joint relies on a specialized cartilage tissue called the labrum. This crucial structure surrounds your shoulder socket, providing essential stability and function. When you experience a shoulder labrum tear, this vital cartilage suffers damage.

A labral tear often causes significant shoulder pain and instability, impacting your daily activities. You might wonder about the frequency of a labral tear. Up to 6% of individuals with shoulder injuries receive a diagnosis of a labral tear after an arthroscopic examination.

Specifically, a superior labrum anterior to posterior (SLAP) labral tear, a common type of labral tear, affects an estimated 6% of people in the general population. Understanding a torn shoulder labrum and its various aspects helps you manage this prevalent injury effectively.

Key Takeaways

• A shoulder labrum tear is damage to the tough tissue that helps keep your shoulder stable.
• Tears can happen from sudden injuries, repeated movements, or simply from getting older.
• You might feel pain, hear clicking sounds, or notice your shoulder feels loose.
• Doctors use exams and special scans like MRI to find a labrum tear.
• Treatment can involve rest and exercises, or surgery for more serious tears.

What is a Shoulder Labrum

Labrum Definition

You have a special structure in your shoulder called the labrum. This is a ring of tough tissue. Think of it as a rim made of fibrocartilage. This fibrocartilage ring attaches to the edges of your shoulder socket, which doctors call the glenoid fossa. The labrum makes your shoulder socket deeper.

This helps your shoulder joint fit together better. The labrum has a triangular shape. It is thicker at the front than it is at the bottom. When you have a labral tear, this important tissue is damaged.

Labrum’s Role

The labrum plays a very important role in your shoulder. It helps keep your shoulder stable. Without a healthy labral structure, your shoulder would be much looser. The labrum works with other parts of your shoulder, like the joint capsule. Together, they create a sealed space inside your joint.

This seal creates a suction effect. This suction pulls liquid and air out of the joint. This action helps your shoulder resist pulling forces and adds to its stability.

The glenoid labrum makes your shoulder more stable in several ways:

• It makes the glenoid socket deeper.
• It increases the surface area where your bones meet.
• It helps keep the ball of your arm bone (humeral head) centered in the socket.
• It acts like a seal to keep pressure inside the joint.
• It helps with something called concavity-compression stability.

Studies show that the labral tissue contributes about 10% to this concavity-compression stability. If you have a labral tear, especially an anterior labral tear, this important pressure inside the joint cannot stay normal. This means your shoulder becomes less stable.

For example, if you have a labral tear, the pressure inside your joint might be near zero. This is very different from a healthy shoulder, where the pressure is much lower, creating that helpful vacuum effect. A labral tear can significantly affect your shoulder’s function.

Causes of a Labrum Tear

A labrum tear can happen for several reasons. You might experience a sudden injury or develop a tear over time. Understanding these causes helps you prevent them or seek proper treatment.

Traumatic Injuries

Sudden, forceful events often cause a labral tear. You might fall directly onto your shoulder. A direct blow to your shoulder can also cause a labral tear. Sometimes, your shoulder can dislocate. This means the ball of your arm bone comes out of its socket. This type of event can easily tear your labrum.

Certain sports and activities commonly lead to traumatic shoulder labrum injuries. You might play throwing sports like baseball, softball, or cricket. Pitchers, for example, use repetitive overhead motions that can stress the labrum. Contact sports such as football, rugby, and hockey also put you at risk.

Direct impacts or falls in these sports can injure your shoulder joint. Overhead sports like tennis, volleyball, and swimming involve movements that can cause labral tears over time.

Repetitive Stress

You can also develop a labral tear from repeated motions. This is called repetitive stress or overuse. If you perform the same shoulder movements many times, your labrum can wear down. This is common in certain jobs or sports.

Activities where you raise your arms over your head can cause labral tears. Weightlifters, gymnasts, and construction workers often do this. Activities where you apply force far from your shoulder also contribute. Striking a hammer or swinging a racquet are examples. Over-the-head lifting is another common cause of labral tears due to repetitive stress.

Degenerative Factors

Your labrum can also tear due to aging. This is called a degenerative labral tear. As you get older, your body tissues naturally wear down. This includes your labrum. Degenerative labral tears are directly linked to aging. They often appear alongside arthritis in your shoulder.

The strength of your shoulder tissues changes with age. Younger individuals have stronger shoulder structures.

For example, the glenoid-labrum region in younger people can withstand more stress. In older individuals, the strength of the joint capsule decreases. The labral tissue itself becomes weaker. This makes it more prone to a labrum tear, even with less force.

Types of Shoulder Labral Tears

You can experience different types of labral tears in your shoulder. Each type affects a specific part of your labrum. Understanding these types of labral tears helps you know more about your injury.

SLAP Tears

A SLAP tear is a common type of labral tear. SLAP stands for Superior Labrum Anterior to Posterior. This means the tear happens at the top of your labrum. It extends from the front to the back.

This area is where your biceps tendon attaches. When you have a SLAP tear, your biceps tendon can also be involved. Diagnosing a SLAP lesion involves a full assessment. This includes your medical history and a physical exam. Doctors use special tests during the physical exam.

One such test is the resisted supination external rotation test. This test checks for discomfort in your shoulder. Imaging, like an MR or MR arthrography, also helps. These scans look for specific signs. You might see a curved signal in the labrum or wide separation between the labrum and glenoid.

Bankart Lesions

A Bankart lesion is another specific labral tear. This tear happens at the front and bottom part of your labrum. It often occurs when your shoulder dislocates. The arm is forced backward. This makes the humeral head dislocate from the glenoid. This action can tear the glenoid labrum and ligaments. Bankart lesions often result from high-energy trauma.

Car accidents or sports collisions can cause them. Falls from sports or heights also lead to these injuries. Repetitive overhead motions can also cause a bankart tear. This happens when ligaments become loose. The most common type of shoulder dislocation is anterior. This is when your arm is forced forward or downward. This pushes the humeral head against the anterior glenoid labrum. This causes a bankart tear.

Posterior Tears

Posterior labral tears are less common. They happen at the back of your shoulder. These injuries can be harder to find. Your shoulder has a complex anatomy. The symptoms can be subtle. Here is how posterior labral tears compare to anterior ones:

Other Tear Classifications

Besides these main types of labral tears, doctors classify them in other ways. You might hear about a Perthes lesion. This is a tear where the anterior inferior labrum pulls away from the glenoid.

It stays attached to the periosteum. Another type is a Reverse Bankart lesion. This is a posterior inferior labral tear. It happens with a posterior shoulder dislocation. These different types of labral tears show how varied these injuries can be.

Symptoms of a Shoulder Labrum Tear

You might experience various symptoms if you have a labral tear. These common symptoms can range from mild discomfort to severe limitations. Recognizing these signs helps you understand your condition.

Pain Characteristics

A labral tear often causes shoulder pain. This pain can feel like a dull ache deep within your shoulder joint. Sometimes, you might feel a sharp, stabbing discomfort. This sharp pain often occurs when you move your arm in certain ways. Many people describe a deep pain or ache. You might also feel a general shoulder pain. This pain can make your shoulder feel unstable.

Mechanical Sensations

You might notice strange sensations in your shoulder. These are called mechanical symptoms. You could hear or feel a distinct popping sensation. Your shoulder might click, grind, or catch when you move it. These feelings happen because the torn labral tissue gets caught in the joint. You might also experience a locking feeling. These sensations are common symptoms of a labral tear.

Instability and Weakness

A labral tear can make your shoulder feel loose or unstable. This happens because the labral tissue helps keep your shoulder joint stable. When the labrum is torn, your shoulder loses some functional stability. It becomes much easier for your arm bone (humerus) to slip out of its socket. This can lead to shoulder instability and repeated dislocations. You might feel a sense that your shoulder is unstable. This feeling is especially noticeable during activities that strain your shoulder.

For example, a Bankart tear is a specific type of labral tear. It often occurs after a shoulder dislocation. This tear makes your shoulder more prone to dislocate again. You might feel apprehension.

This means you worry your shoulder might slip out of place in certain positions. This feeling of instability can be significant. A torn shoulder labrum directly impacts your shoulder’s ability to stay in place.

Restricted Movement

You might find it hard to move your arm fully. A labral tear can cause decreased motion in your shoulder. You might also notice a loss of strength. Activities that involve raising your arm overhead can become difficult. This restricted movement and weakness can affect your daily tasks. You might struggle with simple actions like reaching for something on a high shelf.

Diagnosing a Torn Shoulder Labrum

Diagnosing a labral tear requires careful evaluation. You will undergo several steps to determine if you have a labral tear. This process helps your doctor understand your specific injury.

Physical Examination

Your doctor will begin with a physical examination. They will ask you about your symptoms and how your injury occurred. You will describe your pain and any mechanical sensations.

The doctor will then move your arm in various ways. They will perform specific tests to check your shoulder’s range of motion and stability. These tests can help identify areas of pain or weakness. They also look for signs of instability. This initial assessment provides important clues about your labral injury.

Imaging Studies

Imaging studies help confirm a labral tear. Magnetic Resonance Imaging (MRI) is a common tool.

It provides detailed pictures of your soft tissues. Sometimes, you might receive an injection of contrast dye into your shoulder joint before the MRI. This is called an MR arthrography. The dye helps highlight the labrum and any tears.

MRI could identify only 24 out of the 40 SLAP tears identified by arthroscopy, showing a sensitivity of 60%, specificity of 92.50%, and diagnostic accuracy of 81.67%.

MR arthrography can improve diagnostic accuracy. However, its effectiveness varies.

MR arthrography had an accuracy of 69%, sensitivity of 80%, and a PPV of 29%.

These imaging techniques help doctors visualize the extent of your labral damage.

Differential Diagnosis

Diagnosing a labral tear can be challenging. Its symptoms often resemble those of other joint problems. Your doctor must consider other conditions that cause similar shoulder pain. This process is called differential diagnosis.

Labral tears can present similarly to various other shoulder problems, leading to initial conservative treatment approaches.

Other conditions can mimic the symptoms of a labral tear:

• Tendonitis
• Rotator cuff disorders
• Other shoulder conditions

Your doctor will rule out these other issues. This ensures you receive the correct diagnosis for your torn shoulder labrum. They will create a treatment plan specific to your labral injury.

Treating a Labrum Tear

You have several ways to treat a labral tear. The best approach depends on your specific injury. Doctors consider the type of tear, how severe it is, and your symptoms. They also look at your activity level. Your doctor will discuss various treatment options with you.

Non-Surgical Approaches

You might not need surgery for a labral tear. Many people find relief with non-surgical methods. These methods aim to reduce pain and improve shoulder function.

You can start with rest. Avoid activities that make your shoulder hurt. Your doctor might suggest anti-inflammatory medications. These medicines help reduce pain and swelling. Injections, such as corticosteroids, can also provide temporary pain relief.

Physical therapy is a key part of non-surgical treatment for labral tears. A physical therapist will guide you through specific exercises. These exercises strengthen your rotator cuff muscles. They also improve your shoulder’s stability and range of motion.

Here are some common exercises you might do:

• Cross-Body Stretch: Lie on your side. Position your injured shoulder and elbow at 90 degrees. Gently pull your elbow across your body with your other hand. Hold this for 30 seconds. Do this 2-3 times per session.
• Sleeper Stretch: Start in a similar position to the cross-body stretch. Gently move your wrist and forearm down towards the surface. Hold for 30 seconds. Do this 2-3 times per session.
• Shoulder Flexion in Side-lying: Lie on your side with a light dumbbell. Keep your elbow straight. Raise your arm slightly overhead, parallel to the floor. Do 3 sets of 10-20 repetitions several times a week.
• External Rotation Diagonal: Stand with a resistance band. Anchor it at knee to waist level. Start with your hand in front of your opposite hip pocket. Bend your elbow at a right angle. Flex and rotate your arm across your body. Hold for 1-2 seconds. Perform 3 sets of 12-20 repetitions several times a week.
• Prone Row to External Rotation: Lie on your stomach. Let your arm hang over the side. Hold a light dumbbell. Perform a high row with your elbow in line with your shoulder. Pause. Then rotate your hand upward towards the ceiling. Hold each position for 1-2 seconds. Do 3 sets of 8-12 repetitions several times a week.

Physical therapy can be very effective. Many athletes successfully return to their sports after non-surgical treatment.

You can see the overall success rates for athletes who complete rehabilitation:

Surgical Interventions

You might need surgery if non-surgical methods do not work. Surgery is also an option for severe labral tears or shoulder instability. Doctors often use arthroscopic treatment. This is a minimally invasive procedure. They make small cuts and use a tiny camera to see inside your shoulder.

Arthroscopic repair can reattach the torn labrum to the bone. This is common for Bankart lesions. These tears often cause shoulder instability. The surgeon uses small anchors to secure the labral tissue. This helps stabilize your shoulder joint.

You might consider arthroscopic treatment if:

• You experience shoulder instability.
• You have recurrent dislocations.
• Conservative treatments like physical therapy have not helped you.
• You have a labral tear with a Hill-Sachs lesion. This is especially true for a technique called remplissage.

Doctors usually follow a specific path for treatment:

1. They first suggest conservative treatments. These include anti-inflammatory medications and rest. These help ease your symptoms.
2. They recommend rehabilitation exercises. These strengthen your rotator cuff muscles.
3. They consider arthroscopic surgery if your symptoms continue despite these conservative measures.

Surgery for a labrum tear can have complications. You should discuss these with your doctor.

Surgical Complications:

• Recurrent pain
• Stiffness/arthrofibrosis
• Wound complications
• Bone fracture
• Tendon/ligament failure
• Implant failure
• Hematoma
• Vascular injury
• Nerve palsy
• Wrong-sided surgery

 Medical Complications:

• Venothromboembolism
• Pneumonia
• Respiratory failure
• Arrhythmia
• Congestive heart failure
• Myocardial infarction
• Cerebrovascular accident
• Renal failure

 Anesthetic Complications:

• Unspecified
• Block-related

Women generally have a higher rate of overall complications (8.4%) than men (7.6%) after arthroscopic shoulder surgery. Persistent pain and stiffness are more common in women. Infection and nerve palsy happen more often in men. Other potential issues include re-tearing of the labrum, problems from changes in shoulder biomechanics, and muscle atrophy from long immobilization.

Treatment Decision Factors

Many factors influence the choice between surgical and non-surgical treatment options for a labral tear. Your doctor will consider all these points.

The severity and location of your labral tear are important. Your symptoms and activity level also play a role. Doctors often try non-surgical options first. These include pain management, rest, and activity changes. Rehabilitation exercises improve stability, strength, and range of motion. Heat/cold therapy, ultrasound, or electrical stimulation can also help.

You might need surgery if non-surgical treatments fail. This is also true if your tear is severe and causes major mobility problems.

Some factors make non-surgical treatment less effective. These include your age and how long you have had symptoms. Your playing position in sports and initial range of motion are also factors. X-ray and MRI findings, like a Bennett spur or partial rotator cuff tears, can also point towards surgery. These are “inevitable factors.” You cannot improve them with non-surgical treatment.

However, some factors can improve with non-surgical treatment. For example, tightness in your posterior shoulder muscles (GIRD) can get better. Early improvement in shoulder motion is crucial for good results with non-surgical approaches.

Ultimately, you and your doctor will decide the best course of action. This ensures you get the most effective treatment for your shoulder labral tear.

Recovery After a Labrum Tear

You will begin a recovery journey after treatment for a labral tear. This process aims to restore your shoulder’s strength and function. Your orthopedic team will guide you through each step.

Post-Treatment Care

Your recovery starts immediately after treatment. If you had surgery, you will likely wear a sling. This protects your shoulder as it heals. Your doctor will give you specific instructions for pain management. You will also learn how to care for any surgical incisions. Following these instructions carefully is crucial for proper healing of your labral injury.

Rehabilitation Program

A structured rehabilitation program is vital for your recovery. Physical therapy helps you regain full arm and shoulder function. Your therapist will design exercises to improve your range of motion.

They will also strengthen the muscles around your shoulder. This helps stabilize your shoulder joint. The rehabilitation for a labral tear progresses in stages. You will start with gentle movements. Then you will move to more challenging exercises. Long-term rehabilitation is crucial for regaining maximum arm and shoulder function. It significantly reduces or eliminates pain after a labral tear.

Return to Activity

Returning to your normal activities, especially sports, requires careful planning. Your doctor and physical therapist will determine when you are ready. This decision is based on specific criteria, not just time. You must achieve pain-free range of motion. Your strength should be at least 80% compared to your other arm.

For athletes, the return to sport is a sequential, criterion-based process. It considers patient-reported outcomes, range of motion, strength, and functional performance. Different tests apply for overhead athletes versus those with macrotraumatic shoulder injuries. The “3 P Program” guides this transition: Performance, Practice, and Play.

Return to throwing typically occurs between 16-24 weeks. Sport-specific training usually starts between 24-36 weeks. By three months, you should have most of your range of motion back. Light throwing programs can begin around four months.
