A rotator cuff tear is caused mainly by two things: gradual wear and tear of the shoulder tendons with age, and sudden injuries like falls or heavy lifting. Repetitive overhead motion, poor blood supply, and bone spurs also weaken the tendons over time. In this article, we explain the leading rotator cuff tear causes, common symptoms, key risk factors, and how these tears are diagnosed. You will also learn about proven treatment options at Lux Hospitals so you can protect your shoulder and take timely action for lasting relief.
What Is a Rotator Cuff Tear?
The rotator cuff is a group of four muscles and tendons that stabilize your shoulder and allow it to move freely. A tear happens when one or more of these tendons is damaged or detaches from the bone.
Tears can be partial or complete, and they range from mild to severe. Two main categories exist:
- Degenerative tears from gradual wear
- Acute tears from sudden trauma
- Partial-thickness tendon tears
- Full-thickness complete tears

1. Aging and Tendon Degeneration
Aging is the most common cause of rotator cuff tears. Over time, tendons lose strength, elasticity, and blood supply, making them fragile and prone to splitting.
Most degenerative tears appear after age 40. You are more likely to experience this if you have:
- Natural tendon thinning with age
- Reduced collagen and elasticity
- Years of accumulated shoulder wear
- Tears often in the dominant arm
2. Acute Injury and Trauma
A sudden injury can tear the rotator cuff in an instant. This often happens during a fall onto an outstretched arm or when lifting something too heavy.
Acute tears may also accompany other shoulder trauma. Common triggers include:
- Falling on an outstretched hand
- Lifting heavy objects abruptly
- Sports collisions or accidents
- A shoulder dislocation or fracture

3. Repetitive Overuse and Overhead Motion
Repeating the same shoulder movements gradually frays the tendons. Jobs and sports that demand constant overhead motion carry the highest risk.
This type of overuse shoulder injury builds silently over years. Watch for these activities:
- Painting, carpentry, or construction
- Overhead throwing sports
- Tennis and swimming
- Repetitive lifting or reaching
4. Shoulder Impingement and Bone Spurs
When tendons repeatedly rub against bone, they become inflamed and weakened. Bone spurs from arthritis can pinch the rotator cuff during movement.
This pinching, called impingement, slowly erodes the tendon. Related contributors include:
- Bone spurs narrowing the joint space
- Chronic shoulder impingement
- Thickened bursa tissue
- Underlying shoulder arthritis

5. Poor Blood Supply and Lifestyle
The rotator cuff has naturally limited blood flow, which slows healing and speeds degeneration. Certain lifestyle habits make this worse.
Smoking and poor conditioning reduce tendon health. Contributing factors include:
- Smoking impairing tendon repair
- Diabetes affecting tissue healing
- Sedentary, weak shoulder muscles
- Poor posture straining the joint
Common Risk Factors
Some people are far more likely to develop a rotator cuff injury than others. Knowing your risk helps you take preventive steps early.
Several factors raise your chances of a tear:
- Age over 40
- Manual labor or overhead work
- Family history of tendon problems
- Previous shoulder injuries
- Poor shoulder strength and flexibility

Symptoms You Should Not Ignore
Rotator cuff tears often cause pain, weakness, and limited movement. Some tears develop quietly, while others appear suddenly after injury.
See a specialist if you notice:
- Pain when lifting or lowering the arm
- Weakness raising the shoulder
- Night pain lying on the shoulder
- A cracking sound during movement
- Difficulty reaching behind your back
How a Rotator Cuff Tear Is Diagnosed
Diagnosis begins with a physical exam to test shoulder strength and range of motion. Imaging confirms the size and location of the tear.
Your doctor may recommend:
- Physical strength and movement tests
- X-rays to spot bone spurs
- MRI for detailed tendon imaging
- Ultrasound of soft tissue

Conclusion
A rotator cuff tear rarely has a single cause. Most result from a mix of natural aging, repetitive overhead motion, sudden injury, impingement, and reduced blood supply to the tendons. Understanding these causes helps you recognise early warning signs and protect your shoulder before a small tear becomes a major problem.
If you have persistent shoulder pain, weakness, or night discomfort, do not wait. Early diagnosis leads to simpler, more successful treatment. The experienced shoulder specialists at Lux Hospitals offer everything from targeted physiotherapy to advanced arthroscopic repair. Book a consultation today to restore strength, comfort, and full movement to your shoulder.
