A shoulder labral tear is a tear of the labrum. The labrum is the tissue that holds the end of the arm bone, known as the humerus, in place.
Shoulder labral tears occur from an injury or through long-term wear and tear. Common causes include the following:
A violent overhead reach, such as when trying to stop a fall or slide
Factors that may increase your chance of a labral tear include:
Participation in certain sports, such as:
Falling onto your shoulder
Repetitive movements of the shoulder
Lifting heavy objects
Breaking a fall with your arms
Direct blow to the shoulder
Symptoms may include:
Shoulder and/or arm pain
Catching or loosening feeling of the shoulder
Loss of shoulder range of motion
Weakness to shoulder and/or arm
Pain with shoulder movement
Popping or grinding sensation
Achiness of the shoulder
Your doctor will ask about your symptoms and medical history. A physical exam will be done.
Images may be taken of your shoulder. This can be done with:
MRI scan with contrast
CT scan with contrast
Most labral tears will respond well to non-surgical treatment and may be just one component of a multi-factored pathology of the aging shoulder.
Physical therapy will often address a labral tear from the biomechanical approach of improving the motion and reducing the repetitive injury. If the inflammation and mechanical stress on the structures can be reduced then the tissue has a chance to heal.
Anti-inflammatory medication may be prescribed by the physician in order to jumpstart the reduction in inflammation at the tissue. Once the tissue is no longer irritated it is more likely to respond to conservative treatment by allowing stretch and then fully recovering from the stretch.
At times, the physician may inject cortisone at the specific site of injury, allowing a more targeted reduction in inflammation. Cortisone injections are given infrequently and may provide benefit for 6-8 weeks. During that time, a change in mechanics in motion of the arm is of top importance in order to avoid returning back to the same pattern of motion that caused the injury. A physical therapist will provide the specific education and training that you’ll need following your cortisone injection.
Surgical repair of a Type II SLAP lesions of the young overhead athlete is widely recommended in order to reduce the chance of a shoulder instability in older age. Middle-aged adults (25-45) will likely have other concurrent shoulder pathologies and will do well when all of the problems are surgically addressed. Older adults may require only minimally invasive surgery to the shoulder with removal of ragged or frayed tissue. They may not require a full repair due to having fewer forceful overhead activities than in their youth. These approaches tend to result in high patient satisfaction and return to activity. A shoulder with a Type I labral tear may not require surgery. In this case, you would likely have pain to the shoulder with pressure, in sleeping, and in overhead activity. The pain may change with the weather, suggesting inflammation of the tendons and bursae. At this time, the therapist may demonstrate home modality use to reduce pain and improve tolerance for activities of daily living. Positional change to avoid sleeping on the arm at night will improve blood flow to the area and reduce pain. The therapist will suggest multiple assisted motion patterns of the arm possibly including the use of pulleys for gentle stretch. The therapist will demonstrate safe motion mechanics of the arm and strengthen the supportive structures. You will likely find relief from the use of the home modalities and be able to participate in some light strengthening exercises to improve the surrounding muscles, slowly returning to your normal activities. Because the labrum will still have a lesion, it will be of upmost importance to make these therapy principles part of a long term program to improve functional use of the arm. If you have had surgery to your shoulder, the therapist will follow a specific protocol to apply just the right amount of strain on the shoulder to keep it safe after surgery. A sling may be recommended in the early stages but the therapist will get the arm moving with assistance within a relatively short period of time. You will be educated in how to provide varying levels of assistance to the arm for motion in safe planes in front of the body and eventually throughout the entire range of motion. Once the tissues are healed, the therapist will begin to put resistance on the support structures in order to improve the mechanics of motion and reduce the risk of another injury. The therapist will provide you with instructions and handouts on exercises that you can safely do at home. The goal is to improve the shoulder’s tolerance for exercise and promote appropriate scar formation at the surgical site. Be sure to do your home exercise program! This is the best way to keep the recovery on track.
Follow these guidelines to prevent a shoulder labral tear:
Use the proper technique when playing sports.
Avoid putting yourself at risk for trauma to the shoulder area.
Perform stretching and strengthening exercises that target the shoulder area.
