SLAP tears happen when you tear cartilage in the inner part of your shoulder joint. The tears can be caused by injury or overuse and make it painful or difficult for you to move your shoulder and arm. Left untreated, these tears can cause chronic pain, limit how much you can use your arm and shoulder and lead to more serious shoulder problems.

What is a SLAP tear?

At any point in time, 25% of adults will deal with shoulder pain due to injury or overuse. Superior Labrum, Anterior to Posterior tears (SLAP tears), also known as labrum tears, represent 4% to 8% of all shoulder injuries. The L in SLAP refers to your glenoid labrum. Your labrum plays two important roles in keeping your shoulder functioning and pain free. First, your labrum is a cushion for the top part of your upper arm bone. This cushion helps your upper arm bone stay where it belongs – cradled in your shoulder socket. Second, your labrum is a connection point between your shoulder blade socket and one of your bicep tendons.

The S in SLAP refers to the top of your labrum. When this part of your labrum tears, your upper arm bone loses its cushion and your bicep tendon loses its connection to your shoulder blade socket. As a result, your shoulder hurts and feels unstable. There are several ways to tear your labrum. SLAP tears are common injuries for people who play sports. Your labrum can be torn by an injury or simply over time as you age. Some SLAP tears can be treated with rest and physical therapy, but some may require surgery.

What happens if a SLAP tear goes untreated?

Left untreated, SLAP tear symptoms may get worse, causing chronic shoulder pain and decreasing your ability to use your arm and shoulder.

How long does it take to recover from a SLAP tear?

It can take up to six months to a year to recover from a SLAP tear.

SYMPTOMS AND CAUSES

What causes SLAP tears?

SLAP tears have three causes:

Chronic injury.SLAP tears can happen over time in people who play sports or do exercise that requires lots of overhead motion. Playing baseball or softball, swimming or lifting weights are common causes for SLAP tears. Chronic injury is the most common cause of a SLAP tear.

Acute injury SLAP tears can happen if you try to block a fall with your outstretched arm or you use abrupt jerking movements to lift heavy objects.

Aging SLAP tears can simply happen as your labrum wears out over time. This tear is usually seen in people age 40 and older.

What are SLAP tear symptoms?

Common SLAP tear symptoms include:

• Shoulder pain that can be a persistent dull ache or a sharp pain deep in your shoulder
• Shoulder pain in certain positions, like raising your arm or stretching your arm behind your head.
• Shoulder pain when you do certain things, like throwing a ball or reaching overhead.
• Popping noises or a grinding feeling when you move your shoulder.
• A feeling like your shoulder might pop out of your shoulder blade.

DIAGNOSIS AND TESTS

How do healthcare providers diagnose SLAP tears?

Providers use the following tests to diagnose SLAP tears and determine treatment:

• Physical examination Your doctor will check your arm and shoulder range of motion and strength.
• Magnetic resonance imaging (MRI) or MRI arthrogram.

How do healthcare providers help me decide if I should have SLAP tear surgery?

Healthcare providers weigh the following factors when considering surgery for SLAP tears

• The tear’s classification. Tears are classified based on location and if the tear affects other areas of your shoulder.
• Your age.
• Your typical activities.
• Previous non-surgical treatment.

Are there different types of SLAP tears?

There are several different SLAP types and sub-types. The most common SLAP tear is the type 2 tear. Type 2 tears have several sub-types, each describing different ways a type 2 tear might appear:

• Type 1 In this type of tear, your labrum shows signs of fraying or shredding but still functions. Type 1 tears are often seen in people who are middle-aged or older.
• Type 2 This is the most common SLAP tear type. In Type 2 tears, the labrum and bicep tendon are torn from the shoulder socket.
• Type 3 Torn labrum tissue is caught in the shoulder joint.
• Type 4 In this type, the tear that started in your labrum tears your bicep tendon.

How are SLAP tears treated?

SLAP tear treatment depends on the amount and kind of damage healthcare providers find when they examine your labrum. They might recommend non-surgical therapies first before concluding surgery is the best option. Regardless, SLAP tears can take months to fully heal.

What happens after SLAP tear surgery?

• You’ll wear an arm sling so your injured shoulder isn’t bearing weight. You might need to wear the sling for several weeks to several months.
• Your shoulder might feel stiff.
• Your shoulder might feel weak.
• You still might have limited range of motion.
• Your doctor might recommend light exercise or physical therapy to help you regain strength.

Here’s how you can prevent a SLAP tear:

• Warm up your shoulder muscles with stretches before playing sports.
• Pay attention to how your shoulders feel, and talk to your healthcare provider if you notice changes such as pain or stiffness.
