Physiotherapy in Edmonton for Shoulder

Welcome to Family Physiotherapy's patient resource about Labral Tears.

Since orthopedic surgeons began using a tiny TV camera called an arthroscope to diagnose and treat shoulder problems, they have discovered several conditions that no one knew existed. One of these conditions is an injury to a small structure in the shoulder called the labrum. A labral tear can cause pain and a catching sensation in the shoulder. Labral tears can be very difficult to diagnose.

This document will help you understand:

• where and what the labrum is
• what tests your doctor will run to diagnose the problem
• what you can do to relieve your pain

What is the labrum?

The shoulder is made up of three bones: the scapula (shoulder blade), the humerus (upper arm bone), and the clavicle (collarbone).

Shoulder Bones

A part of the scapula, called the glenoid, makes up the socket of the shoulder. The glenoid is very shallow and flat. The labrum is a rim of soft tissue that makes the socket more like a cup. The labrum turns the flat surface of the glenoid into a deeper socket that molds to fit the head of the humerus.

Glenoid

The rotator cuff connects the humerus to the scapula. The rotator cuff is formed by the tendons of four muscles: the supraspinatus, infraspinatus, teres minor, and subscapularis.

Rotator Cuff Muscles

Tendons attach muscles to bones. Muscles move the bones by pulling on the tendons. The rotator cuff helps raise and rotate the arm. As the arm is raised, the rotator cuff also keeps the humerus tightly in the glenoid of the scapula.

The soft labral tissue can be caught between the glenoid and the humerus. When this happens, the labrum may start to tear. If the tear gets worse, it may become a flap of tissue that can move in and out of the joint, getting caught between the head of the humerus and the glenoid. The flap can cause pain and catching when you move your shoulder. Several tendons and ligaments attach to the labrum that help maintain the stability of the shoulder. So when the labrum tears, the shoulder often becomes much less stable.

What causes labral tears?

Labral tears are often caused by a direct injury to the shoulder, such as falling on an outstretched hand. The labrum can also become torn from the wear and tear of activity, a condition called overuse. An injured labrum can lead to shoulder instability. The extra motion of the humerus within the socket causes additional damage to the labrum. An extremely unstable shoulder may slip or dislocate. This can also cause the labrum to tear.

The biceps tendon attaches to the front part of the labrum. The biceps is the large muscle on the front of your upper arm. Sports can cause injuries to the labrum when the biceps tendon pulls sharply against the front of the labrum. Baseball pitchers are prone to labral tears because the action of throwing causes the biceps tendon to pull strongly against the top part of the labrum. Weightlifters can have similar problems when pressing weights overhead. Golfers may tear their labrum if their club strikes the ground during the golf swing.

What does a labral tear feel like?

The main symptom caused by a labral tear is a sharp pop or catching sensation in the shoulder during certain shoulder movements. This may be followed by a vague aching for several hours. At other times, the tear may not cause any pain. Shoulder instability from a damaged labrum may cause the shoulder to feel loose, as though it slips with certain movements.

When you visit Family Physiotherapy, our physiotherapist may suspect a labral tear based on your medical history. We will ask you questions about your pain and past injuries to your shoulder that may suggest labral damage.

In the physical examination, there are several shoulder movements that can bring on the symptoms. You may feel a catching sensation as your arm is raised, and there may be pain when the arm is held overhead. If your arm is held in front of your body, with the palm of the hand facing downward, you may feel pain when our therapist tries to push down on your arm.

Some patients may be referred to a doctor for further diagnosis. Once your diagnostic examination is complete, the physiotherapists at Family Physiotherapy have treatment options that will help speed your recovery, so that you can more quickly return to your active lifestyle.

Non- surgical Rehabilitation

Even nonsurgical treatment requires a rehabilitation program. Some evidence suggests that shoulder instability may eventually make labral tears worse. The goal of physiotherapy will be to strengthen the rotator cuff muscles to make your shoulder more stable.

When you begin your physiotherapy program at Family Physiotherapy, we will initially need to control your pain and inflammation. Initial treatment for pain control is usually rest, in addition to heat or ice.  Patients may also want to consult with their doctor or pharmacist regarding the use of anti-inflammatory medication, such as aspirin or ibuprofen.  Hands-on treatment and various types of exercises will be applied by our physiotherapist to improve the range of motion in your shoulder and the nearby joints and muscles.

Later, we will direct you to do strengthening exercises to improve the strength and control of the rotator cuff and shoulder blade muscles. Our physiotherapist will help you retrain these muscles to keep the ball of the humerus in the glenoid. This will improve the stability of your shoulder and help it move smoothly during all your activities.

Although the amount of time required for recovery varies, you may need physiotherapy treatments for about four to six weeks. Most patients are able to get back to their activities with full use of their arm within this amount of time.

Eventually our therapist will put you on a home program of exercise to keep the muscles strong and flexible. This should help you avoid future problems.

Post-surgical Rehabilitation

Rehabilitation after surgery is more complex. You will probably need to wear a sling to support and protect the shoulder for several weeks after surgery. Our physiotherapist can develop a personalized recovery program for your rehabilitation. Depending on the surgical procedure, you will probably need to attend therapy sessions for one to two months, and you should expect full recovery to take up to four to six months if you are expecting to participate in athletics.

Getting the shoulder moving as soon as possible is important. However, this must be balanced with the need to protect the healing tissues. Our first few therapy treatments will focus on controlling the pain and swelling from surgery. Ice and electrical stimulation treatments may help. Our physiotherapist may also use massage and other types of hands-on treatments to ease muscle spasm and pain.

Physiotherapy proceeds quickly after a simple arthroscopic surgery to clean up the frayed edges or loose parts of the labrum. Our physiotherapist will have you begin with range-of-motion exercises and gradually work into active stretching and strengthening. Overhand athletes start their sports gradually within four to six weeks. They can usually return to competition within three months.

After surgery to repair the labrum, our physiotherapists usually begin with passive exercises. In passive exercises, the shoulder joint is moved, but your muscles stay relaxed. Our physiotherapist gently moves your joint and gradually stretches your arm. You may also be taught how to do passive exercises at home.

Active physiotherapy usually starts about six weeks after repair surgery. Our active range-of-motion exercises will help you regain shoulder movement using your own muscle power. Light isometric strengthening exercises are started about this time. These exercises work the muscles without straining the healing joint.

By about the tenth week, we will have you begin doing more active strengthening. Our exercises will focus on improving strength and control of the rotator cuff muscles. They help tighten the ball of the humerus in the glenoid socket and can improve the stability of the shoulder. A stronger and more stable shoulder helps keep the ball of the humerus centered in the socket during all your activities.

Some of the exercises you will do are designed get your shoulder working in ways that are similar to your work tasks and sport activities. Our physiotherapist will help you find ways to do your tasks that don't put too much stress on your shoulder. Before your physiotherapy sessions end, our physiotherapist will teach you a number of ways to avoid future problems.

Labral tears are difficult to see, even in a magnetic resonance imaging (MRI) scan.

An MRI scan is a special imaging test that uses magnetic waves to show the tissues of the shoulder in slices.

The MRI scan shows soft tissues such as tendons and ligaments as well as bones.

Labral tears may be seen using computed tomography (CT) scan and a special dye. A CT scan is an older test that uses computer-enhanced X-rays to show slices of the shoulder.

The soft tissues do not show up in a CT scan, but the special dye does. The dye shows the outline of the labrum. If there is a tear, the dye may leak into it and show up on the CT scan.

However, MRI and CT scans are not very accurate in detecting labral tears. Confirming the diagnosis of a labral tear can be extremely difficult. A surgeon may need to look into your shoulder using an arthroscope. The arthroscope is a small TV camera that is inserted into the shoulder joint through a very small incision. The surgeon can then see pictures of the joint on a TV screen. This allows the surgeon to look directly at the labrum to see if it is torn.

Arthroscope

Your doctor may suggest a cortisone injection if you have trouble getting your pain under control. Cortisone is a strong anti-inflammatory medication. It can provide good relief, although its effects are temporary.

If your symptoms don't go away, you may need surgery. Surgical treatment for this condition is still evolving. Surgeons have not known about the problem long enough to adequately evaluate the results of different treatments.

The arthroscope is commonly used to treat many labral tears. If the tear is small and is mostly getting caught as you move the shoulder, simply removing the frayed edges and any loose parts of the labrum may get rid of your symptoms. This is called labral debridement.

If the tear is larger, the shoulder may also be unstable. If this is the case, the labral tear may need to be repaired, rather than simply removed. Several new techniques allow surgeons to place “anchors” into the bone around the shoulder joint and reattach the labrum using the arthroscope. There are many variations of these anchors, but most are drilled into the bone and have sutures (stitches) attached that are then used to tie the labrum down to the bone and enable the labrum to heal back in the appropriate position.

Open Procedure

Open procedures are rarely used today for repair of labral tears. The arthroscopic techniques have become increasingly refined and are today the preferred method of treatment. If for some reason the tear is repaired open, the surgeon will need to make an incision in the front of the shoulder. The main drawback of making the larger incision is that it will probably take you longer to recover from surgery.
