Rotator Cuff Tear! Symptoms, Causes, Diagnosis, Treatment & Exercises

Rotator Cuff Tear:

rotator cuff tearThe rotator cuff is a made up of four muscles in the shoulder, connecting the humerus to the scapula. The rotator cuff tendons provide stability to the shoulder; the muscles allow the shoulder to rotate.


Rotator cuff includes four muscles:

Each muscle of the rotator cuff inserts at the scapula and has a tendon that attaches to the humerus. The tendons and other tissues together form a cuff around the humerus.

Symptoms of a rotator cuff tear

rotator cuff symptomPain at rest and at night, concretely if lying on the affected shoulder Pain in lifting and lowering your arm or with specific forms of movements

Weakness in lifting and rotating of arm
Crepitus or crackling sensation when moving shoulder in certain positions
Snapping sensation and immediate weakness in the upper arm.

Causes of a rotator cuff tear

There are two main causes of rotator cuff tears are -Injury and Degeneration.

Acute Tear-

Fall down on the outstretched arm or lift something too heavy with a jerking movement. This type of tear may occur with other shoulder injuries, such as broken collarbone or dislocated shoulder.

Degenerative Tear-

Most tears are the result of wearing down of the tendon that occurs gradually over time. This degeneration naturally occurs as we age. Rotator cuff tears are more in the dominant arm. If have a degenerative tear in one shoulder, there is a more preponderant risk for a rotator cuff tear in the other shoulder -- even have no pain in that shoulder. Several factors contribute to chronic rotator cuff tears-

Repetitive stress- Repeating the same shoulder forms of movements, again and again, can stress rotator cuff muscles and tendons. Baseball, rowing, tennis, and weightlifting are examples of sports that can put at risk for overuse tears.

Lack of blood supply- As we get older, the blood supply in rotator cuff tendons lessens. Without a good blood supply, the body's natural ability to rehabilitate tendon damage is impaired. This can ultimately lead tendon tear.

Bone spurs- As we age, bone spurs often develop on the underside of acromion bone. When we lift arms, the spurs rub on rotator cuff tendon. This condition is also known as shoulder impingement, and over time will weaken the tendon and make it more liable to tear.

Risk Factors

Because most rotator cuff tears are largely caused by normal wear and tear that goes along with aging, people over 40 are at more preponderant risk.

People who do repetitive lifting or overhead activities are also at risk for rotator cuff tears. Athletes are especially vulnerable susceptible to overuse tears, categorically tennis players and baseball pitchers. Painters, carpenters, and others who do overhead work additionally have a more preponderant chance of tears.

Although overuse tears caused by sports activity or overhead work additionally occur in younger people, most tears in adults are caused by a traumatic injury, like a fall.

Diagnosis

Your physicians will suspect a rotator cuff tear predicated on your clinical history and findings from a series of clinical tests.

A diagnostic ultrasound scan is the most precise method to diagnose the size and location of rotator cuff tear. MRI’s may show a rotator cuff tear but have additionally been known to miss a tear. X-rays have little diagnostic value when a rotator cuff tear is suspected.

Rotator cuff Physical examination-
Supraspinatus-
 Patient position standing or sitting upright position.The arm should be anteriorly flexed at the shoulder level with the pronated arm.The patient should resist downward pressure applied on the forearm by the examiner.if pain or weakness that indicates supraspinatus tear.
Supraspinatus & Infraspinatus-
Patient position standing or sitting upright position with affected arm adducted(slight abduct) and elbow flexed.If failure to maintain an active full external rotation that indicates a supraspinatus & infraspinatus tear.
Subscapularis tear-
Patient position standing with affected arm against the stomach with elbow anterior to the midaxillary line.The patient is asked to press the belly.Failure to maintain the elbow anterior to the mid-axillary line while pressing against the belly indicates subscapularis tendon tear.
Neer's test-
Patient position standing or sitting upright position.The examiner will passively elevate the pronated arm of the patient above the level of the shoulder.
Pain at the anterolateral aspect of the shoulder indicates subacromial impingement.
Hawkin's test-
Patient position standing or sitting upright position with arm fully adducted & forwardly flexed.The elbow is flexed.

The examiner will place one hand on the patient shoulder and apply internal rotation to the affected arm with the other hand.
Pain at the shoulder indicates subacromial impingement.
Drop arm test-
Patient position standing or sitting upright position.The patient is asked to hold the affected arm in abduction at the level of the shoulder then smoothly adduct the arm.
A patient suffering from rotator cuff tear will not be able to hold the arm in abduction and the arm will drop rapidly.

Treatment

Initial treatment of rotator cuff tendinitis involves managing pain and swelling to promote healing. This can be done by:

rotator cuff exercisesAvoiding activities that cause pain
Applying cold packs to your shoulder three to four times per day
Taking non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen and naproxen
Additional treatment may include:

Physical Therapy-
Rotator Cuff RepairYour physicians may refer you to a physical therapist. Physical therapy will initially consist of stretching and other passive exercises to avail renovate range of kineticism and facilitate pain. Once the pain is under control, your physical therapist will teach you exercises to avail regain strength in arm and shoulder.

Steroids-

If rotator cuff tendinitis is not being managed by more conservative treatment, your physicians may recommend a steroid injection. This is injected to the tendon to reduce inflammation, which reduces pain.

Surgery:
If nonsurgical treatment isn’t successful, your doctor may recommend surgery.

Home Care for Your Shoulder:

There are several things you can do to avail reduce pain from rotator cuff tendinitis. These techniques can additionally avail obviate rotator cuff tendinitis or another flare-up of pain.

 Self-care for Shoulder includes:

Using good posture while sitting

Taking breaks from perpetual activities

Avoiding lifting arms repetitively over your head

Avoid carrying a bag on one shoulder

Avoid sleep on the same side every night

Carrying things close to your body
