Shoulder Impingement Syndrome
Shoulder impingement syndrome occurs when the tendons of the rotator cuff become compressed between the head of the humerus bone and a part of the shoulder blade. Shoulder impingement syndrome can lead to a chronic inflammatory condition that may eventually develop into the weakening of the rotator cuff tendons. Ultimately, this situation could result in a torn rotator cuff.
Cause & Symptoms
Shoulder impingement Cause
Rotator cuff pain is common in both young athletes and middle-aged people. Young athletes who use their arms overhead for swimming, baseball, and tennis are particularly vulnerable. Those who do repetitive lifting or overhead activities using the arm, such as paper hanging, construction, or painting are also susceptible.
Pain may also develop as the result of a minor injury. Sometimes, it occurs with no apparent cause.
Rotator cuff pain commonly causes tenderness in the front and side of the shoulder.
You may have pain and stiffness when you lift your arm. There may also be pain when the arm is lowered from an elevated position.
Beginning symptoms may be mild. Patients frequently do not seek treatment at an early stage.
These symptoms may include:
Minor pain that is present both with activity and at rest
Pain radiating from the front of the shoulder to the side of the arm
Sudden pain with lifting and reaching movements
Athletes in overhead sports may have pain when throwing or serving a tennis ball.
As the problem progresses, the symptoms increase:
Pain at night
Loss of strength and motion
Difficulty doing activities that place the arm behind the back, such as buttoning or zippering
If the pain comes on suddenly, the shoulder may be severely tender.
All movement may be limited and painful.
Medical History and Physical Examination
Your doctor will test your range of motion by having you move your arm in different directions.
After discussing your symptoms and medical history, your doctor will examine your shoulder. He or she will check to see whether it is tender in any area or whether there is a deformity.
To measure the range of motion of your shoulder, your doctor will have you move your arm in several different directions. He or she will also test your arm strength.
Your Great Lakes Orthopedics & Sports Medicine orthopedic surgeon will check for other problems with your shoulder joint. He or she may also examine your neck to make sure that the pain is not coming from a “pinched nerve,” and to rule out other conditions, such as arthritis.
Other tests which may help your doctor confirm your diagnosis include:
X-rays. Becauses x-rays do not show the soft tissues of your shoulder like the rotator cuff, plain x-rays of a shoulder with rotator cuff pain are usually normal or may show a small bone spur. A special x-ray view, called an “outlet view,” sometimes will show a small bone spur on the front edge of the acromion.
Magnetic Resonance Imaging (MRI) and Ultrasound. These studies can create better images of soft tissues like the rotator cuff tendons. They can show fluid or inflammation in the bursa and rotator cuff. In some cases, partial tearing of the rotator cuff will be seen.

|The Physical Therapy team at Great Lakes Orthopedics offer a wide range of programs and specialized services to help our patients restore and maintain their physical strength, performance skills, and levels of function. Our well-trained, professional staff utilize the most progressive treatment options and techniques to ensure the best possible recoveries.|
The goal of treatment is to reduce pain and restore function. In planning your treatment, your doctor will consider your age, activity level, and general health.
In most cases, initial treatment is nonsurgical. Although nonsurgical treatment may take several weeks to months, many patients experience a gradual improvement and return to function.
Rest. Your doctor may suggest rest and activity modification, such as avoiding overhead activities.
Non-steroidal anti-inflammatory medicines. Drugs like ibuprofen and naproxen reduce pain and swelling.
Physical therapy. A physical therapist will initially focus on restoring normal motion to your shoulder. Stretching exercises to improve range of motion are very helpful. If you have difficulty reaching behind your back, you may have developed tightness of the posterior capsule of the shoulder (capsule refers to the inner lining of the shoulder and posterior refers to the back of the shoulder). Specific stretching of the posterior capsule can be very effective in relieving pain in the shoulder.
Once your pain is improving, your therapist can start you on a strengthening program for the rotator cuff muscles.
Steroid injection. If rest, medications, and physical therapy do not relieve your pain, an injection of a local anesthetic and a cortisone preparation may be helpful. Cortisone is a very effective anti-inflammatory medicine. Injecting it into the bursa beneath the acromion can relieve pain.
