Understanding the Rotator Cuff

The shoulder, also known as the glenohumeral joint, is a ball-and-socket joint made up of three bones:

• Humerus (upper arm bone) - The head of the humerus fits into the shoulder socket (glenoid) of the scapula to form the joint.
• Scapula (shoulder blade) – A sturdy, flat, triangular bone located on the upper back (dorsal thorax) between the second and eighth ribs, connecting the clavicle to the humerus.
• Clavicle (collarbone) – A slender, S-shaped long bone acting as a strut between the sternum (breastbone) and scapula (shoulder blade), forming the anterior part of the pectoral girdle.

The rotator cuff is a group of four muscles and their tendons that stabilize the glenohumeral joint and allow controlled movement. These muscles originate from the scapula and attach to the humerus:

• Supraspinatus – Helps lift the arm outward
• Infraspinatus – Rotates the arm outward
• Teres minor – Assists with external rotation
• Subscapularis – Responsible for internal rotation of the shoulder

These tendons keep the upper arm bone centered in the shoulder socket during movement. Pain from rotator cuff tears is often felt over the lateral aspect of the shoulder.

A small fluid-filled sac called the bursa sits between the rotator cuff and the acromion, part of the shoulder blade. The bursa helps the tendons glide smoothly. When the rotator cuff is injured, the bursa may become inflamed as well.

What Is a Rotator Cuff Tear?

A rotator cuff tear is a tendon tear that occurs when one or more of the rotator cuff tendons partially or completely detach from the bone. The supraspinatus tendon is the most commonly affected.

A torn rotator cuff may involve one or more tendons and can significantly affect shoulder function, leading to pain, weakness and limited range of motion.

Types of Rotator Cuff Tears

Partial Tear (Incomplete Tear)

The tendon is damaged but not completely severed.

Full-Thickness Tear (Complete Tear)

The tendon is fully torn and may separate from the bone, creating a gap.

Tears can range from small to large and may worsen over time if untreated.

Causes of Rotator Cuff Tears

There are two primary causes of rotator cuff tears:

Acute Injury

These tears occur suddenly, often due to trauma such as:

• Falling onto an outstretched arm
• Lifting a heavy object with a jerking motion
• Shoulder dislocation
• Traumatic impact during sports or accidents

Acute inflammation is a typical response to these injuries, causing pain, swelling and weakness.

Degenerative Wear and Tear

Most rotator cuff tears develop gradually due to tendon degeneration over time. Contributing factors include:

• Repetitive overhead movements
• Occupations requiring overhead work
• Reduced blood supply to the tendons with age
• Bone spurs that rub on the tendon (shoulder impingement)
• Natural aging changes
• Poor posture, which may increase mechanical stress on the shoulder

Individuals over age 40 are at increased risk. If one shoulder has a degenerative tear, the opposite shoulder may also be at risk.

Symptoms of a Rotator Cuff Tear

Common symptoms include:

• Shoulder pain at rest or at night, especially when lying on the affected side
• Pain with lifting or lowering the arm
• Weakness with overhead activities
• Difficulty reaching behind the back
• Limited range of motion
• Clicking or crackling sensations (crepitus) with movement

If rotator cuff tears are not addressed, shoulder pain and dysfunction may develop, leading to persistent discomfort that interferes with daily routines.

Acute tears often cause sudden, intense pain and immediate weakness. Tears may begin with mild discomfort that gradually worsens.

If shoulder pain persists for more than a few days or interferes with sleep or daily activities, evaluation by a shoulder specialist is recommended.

How Rotator Cuff Tears Are Diagnosed

At OrthoTexas, evaluation begins with a comprehensive physical examination, including review of symptoms and medical history. This examination includes:

• Assessment of strength and range of motion
• Special tests to evaluate individual rotator cuff muscles
• Evaluation for associated conditions such as biceps tendon injury or shoulder impingement

Imaging studies may include:

• X-rays to evaluate bone spurs or arthritis
• MRI to assess the size and location of the tear
• Ultrasound in select cases

Accurate diagnosis helps guide the most appropriate treatment plan.

Non-Surgical Treatment for Rotator Cuff Tears

Many rotator cuff tears, especially partial or small tears, can be managed without surgery. Treatment options range from conservative approaches to surgical repair when necessary.

Activity Modification

Avoiding overhead or aggravating activities allows inflammation to decrease.

Medications

Nonsteroidal anti-inflammatory drugs (NSAIDs) may help reduce pain and inflammation.

Physical Therapy

Targeted rehabilitation focuses on:

• Strengthening the surrounding shoulder muscles
• Improving scapular stability
• Restoring range of motion
• Reducing mechanical stress on the tendon

Corticosteroid Injections

In some cases, injections into the subacromial space may reduce inflammation and pain.

Conservative treatment can significantly improve symptoms and function for many patients.

Prevention and Management of Rotator Cuff Tears

Preventing rotator cuff injuries involves strengthening the shoulder and maintaining proper mechanics.

Regular strengthening exercises targeting the rotator cuff muscles can help stabilize the shoulder and reduce the risk of tears. Maintaining good posture reduces unnecessary stress on the shoulder joint. Limiting repetitive overhead activities and heavy lifting can also lower injury risk.

For individuals with an existing rotator cuff tear, early management is important. Physical therapy helps restore strength and flexibility. In more severe or persistent cases, surgical repair may be recommended to restore shoulder function.

Prompt evaluation and appropriate care can improve long-term shoulder health.

When Is Surgery Recommended?

Shoulder surgery may be considered if:

• Pain persists despite appropriate non-surgical treatment
• Significant weakness affects daily activities
• There is a large or full-thickness tear
• An acute traumatic tear occurs in an active individual

Surgery is typically discussed after conservative treatments have been attempted, though early intervention may be recommended in certain cases.

Arthroscopic Rotator Cuff Repair

Most rotator cuff repairs are performed arthroscopically using minimally invasive techniques.

During arthroscopy:

• Small incisions are made around the shoulder
• A camera is inserted to visualize the joint
• Specialized instruments reattach the tendon to the bone using anchors

If other conditions are present, such as biceps tendon injury, bone spurs or AC joint arthritis, they may be addressed during the same procedure.

This approach typically results in smaller incisions and less disruption to surrounding tissues compared to traditional open surgery.

Recovery After Rotator Cuff Surgery

Recovery requires patience and commitment to rehabilitation.

Typical recovery includes:

• Sling use for several weeks
• Gradual progression of motion under supervision
• Structured physical therapy
• Avoidance of lifting during early healing

Full recovery may take four to six months or longer, depending on tear size and individual factors. Tendon healing to bone takes time, and following post-operative instructions is essential for optimal outcomes.

Living With a Rotator Cuff Injury

Living with a rotator cuff injury can be challenging, but symptoms can often be managed with appropriate care. Avoiding heavy lifting and repetitive overhead movements can prevent further strain. Ice or heat may help relieve discomfort.

Strengthening exercises guided by a physical therapist can improve shoulder stability and reduce weakness. When conservative measures are insufficient, surgical treatment may be discussed.

With a tailored treatment plan, many individuals experience meaningful improvement in pain and function.

Rotator Cuff Tear Arthropathy

In severe cases, a large rotator cuff tear may lead to rotator cuff tear arthropathy, a condition involving tendon deficiency and shoulder arthritis. Advanced surgical options, such as reverse total shoulder replacement, may be considered to restore function.
