A supraspinatus tear is one of the most common shoulder tendon injuries I see in orthopedic practice. The supraspinatus is one of the four tendons of the rotator cuff, and it plays an important role in lifting the arm and helping the shoulder stay stable during movement. When this tendon becomes torn, patients may notice pain, weakness, difficulty reaching overhead, and discomfort at night, especially when lying on the affected side.[1][2]

In Bangladesh, many patients describe this problem simply as shoulder pain and continue daily work for a long time before seeking proper evaluation. Some blame it on sleeping posture. Some think it is only a muscle pull. Others take pain medicine on and off while the weakness slowly gets worse. One important point I want Bangladeshi patients to understand is that a supraspinatus tear can range from a small partial tear to a more serious full-thickness tear, and the right treatment depends on the size of the tear, the patient’s age, activity level, symptoms, and functional needs.[1]

Not every supraspinatus tear needs surgery. At the same time, not every persistent painful shoulder should be ignored. The key is correct diagnosis, realistic treatment planning, and a practical rehabilitation plan that fits the patient’s daily life in Dhaka or elsewhere in Bangladesh.

What is the supraspinatus tendon?

The supraspinatus tendon is part of the rotator cuff. The rotator cuff is a group of muscles and tendons that help stabilize the shoulder joint and guide arm movement. The supraspinatus specifically helps begin arm elevation and supports smooth shoulder motion.[1][2]

Why this tendon is commonly affected

Among rotator cuff tendons, the supraspinatus is especially vulnerable because it passes through a narrow space under the acromion and is exposed to both wear-and-tear stress and injury. AAOS notes that most rotator cuff tears involve the supraspinatus tendon.[1]

What causes a supraspinatus tear?

A supraspinatus tear may happen suddenly or develop gradually over time.

Acute injury

A sudden tear may happen after:

• a fall on an outstretched hand
• lifting something heavy with a jerking movement
• a road traffic injury
• sudden forceful traction on the arm
• a shoulder dislocation or traumatic event

When this happens, patients may feel sharp pain and immediate weakness.[1]

Degenerative or wear-related tearing

Many supraspinatus tears develop slowly. Repeated overhead activity, age-related tendon degeneration, poor shoulder mechanics, and long-term impingement can all contribute.[1][2]

In my practice, I often see this pattern in:

• office workers with long-term poor posture
• homemakers who do repeated overhead work
• laborers and shop workers
• people who frequently lift from awkward positions
• older adults with chronic shoulder pain
• athletes and active adults with repeated overhead motion

What symptoms can a supraspinatus tear cause?

Symptoms vary from person to person, and small tears may first look like tendinitis or a simple strain.

Common symptoms

Patients may experience:

• pain on the outer or upper part of the shoulder
• pain when lifting the arm
• difficulty reaching overhead
• weakness while holding or raising the arm
• night pain, especially when lying on the affected side
• painful arc of movement
• clicking or discomfort with certain motions

AAOS and MedlinePlus both describe pain at rest or at night, pain with lifting, and weakness with shoulder movement as common features of rotator cuff tears.[1][2]

Partial tear versus full tear

A partial tear means the tendon is damaged but not completely detached. A full-thickness tear means the tendon is torn through its full depth, and in some cases part of the tendon is detached from bone.[1]

This difference matters because treatment planning may change depending on how severe the tear is.

How do I suspect a supraspinatus tear?

Shoulder pain is not always a torn tendon. Many patients with neck-related pain, frozen shoulder, arthritis, or bursitis may feel similar symptoms. That is why I do not diagnose a supraspinatus tear from pain alone.

What I look for during assessment

When I evaluate patients with this problem, I usually focus on:

• where the pain is located
• whether the arm is weak
• whether night pain is present
• whether overhead movement is difficult
• whether there was a clear injury
• whether neck pain may be contributing
• whether there are signs of shoulder stiffness, instability, or another cuff tendon problem

Some patients also have overlapping pain patterns like Shoulder Pain and Pain Around the Neck, which is why a full shoulder and neck examination is important.

How is the diagnosis confirmed?

A proper diagnosis usually involves a combination of history, clinical examination, and imaging.

Physical examination

I assess:

• range of motion
• strength during arm elevation
• painful arc
• tenderness
• impingement signs
• neck contribution
• scapular movement
• whether there is shoulder stiffness or instability

Imaging tests

X-rays

X-rays do not show the tendon directly, but they may help identify arthritis, bone spurs, or other structural issues.

Ultrasound

In some settings, ultrasound can help detect rotator cuff tears, especially when done by an experienced team.[1]

MRI

MRI is often helpful when I need to assess the size of the tear, associated tendon damage, muscle quality, and surgical planning.
