What is impingement of the supraspinatus tendon?

What is impingement of the supraspinatus tendon?

Impingement occurs when the supraspinatus tendon or the region where the supraspinatus tendon is attached to the humerus, contacts the under surface of the acromion and the coraco-acromial ligament. ‍ SYMPTOMS. ‍ In patients with impingement, pain occurs as the arm is lifted up away from the side of the body.

Where is the supraspinatus tendon impinged?

The tendon of the supraspinatus commonly impinges under the acromion as it passes between the acromion and the humeral head.

What muscle tendon is often involved in shoulder impingement syndrome?

Shoulder impingement syndrome is a syndrome involving tendonitis (inflammation of tendons) of the rotator cuff muscles as they pass through the subacromial space, the passage beneath the acromion. It is particularly associated with tendonitis of the supraspinatus muscle.

Is the supraspinatus involved in shoulder impingement?

The shoulder impingement syndrome refers to a condition in which the supraspinatus tendon and subacromial bursa are chronically entrapped between the humeral head inferiorly and either the anterior acromion itself, spurs of the anterior acromion or acromioclavicular joint, or the coracoacromial ligament superiorly.

What causes impingement of the supraspinatus?

The causes of supraspinatus tendonitis can be broken down into extrinsic and intrinsic factors. Extrinsic factors are further broken down into primary impingement, which is a result of increased subacromial loading, and secondary impingement, which is a result of rotator cuff overload and muscle imbalance.

How do you fix supraspinatus impingement?

Treatments for impingement syndrome include rest, ice, over-the-counter anti-inflammatory medications, steroid injections and physical therapy.

1. Physical therapy is the most important treatment for shoulder impingement syndrome.
2. Ice should be applied to the shoulder for 20 minutes once or twice a day.

How does an impingement occur?

Shoulder impingement occurs when the tendon rubs against the acromion. The causes of this impingement include: Your tendon is torn or swollen. This can be due to overuse from repetitive activity of the shoulder, injury or from age-related wear and tear.

What does impingement mean in medical terms?

Medicine/Medical. the act or fact of interfering with something, especially a nerve, through contact or pressure: Impingement on the nerves can be relieved by removing the portion of the bone compressing the neural structures.

What is supraspinatus muscle?

Supraspinatus is the smallest of the 4 muscles which comprise the Rotator Cuff of the shoulder joint specifically in the supraspinatus fossa. It travels underneath the acromion.

How does a shoulder impingement occur?

What is the function of the supraspinatus?

As part of the Rotator Cuff, supraspinatus helps to resist the gravitational forces which act on the shoulder joint to pull from the weight of the upper limb downward. It also helps to stabilize the shoulder joint by keeping the head of the humerus firmly pressed medially against the glenoid fossa of the scapula.

How serious is shoulder impingement?

If left untreated, a shoulder impingement can lead to more serious conditions, such as a rotator cuff tear. Physical therapists help decrease pain and improve shoulder motion and strength in people with shoulder impingement syndrome.

How does supraspinatus tendonitis lead to other shoulder problems?

Secondary Shoulder Impingement: Dynamic shoulder instability – weakness in the rotator cuff muscles leads to poor control and thus friction Supraspinatus Tendonitis may develop in isolation but it is often associated with other shoulder problems such as subacromial bursitis, shoulder impingement syndrome, biceps tendonitis and rotator cuff tears.

What does it mean to have shoulder impingement syndrome?

What is shoulder impingement syndrome? Shoulder impingement occurs when the top outer edge of your shoulder blade, called the acromion, rubs against (“impinges on”) or pinches your rotator cuff beneath it, causing pain and irritation.

What are the symptoms of supraspinatus rotator cuff tear?

Shoulder And Arm Weakness: Considerable weakness or weakness with no pain indicates a full thickness rotator cuff tear aka supraspinatus tendon full thickness tear Functional Limitation: Any activities at or above shoulder height may be painful and restricted e.g. reaching up to a cupboard, hanging up washing and washing/brushing your hair

What causes impingement at the end of the clavicle?

It meets with the end of your collar bone (clavicle) at your shoulder. Shoulder impingement occurs when the tendon rubs against the acromion. The causes of this impingement include: Your tendon is torn or swollen.
