Cuff Tear
A Cuff Tear is a condition where one or more of the tendons in the Shoulder Cuff become torn or damaged. The cuff is a group of four muscles and tendons that stabilize the shoulder joint and allow smooth arm movements such as lifting, rotating, and reaching overhead.
These tendons connect the shoulder muscles to the Humerus (upper arm bone). When the tendon is torn due to injury, degeneration, or overuse, it can cause shoulder pain, weakness, and difficulty in arm movement.

What is Cuff Tear
A Cuff Tear is a condition where one or more of the tendons in the Shoulder Cuff become torn or damaged. The cuff is a group of four muscles and tendons that stabilize the shoulder joint and allow smooth arm movements such as lifting, rotating, and reaching overhead.
These tendons connect the shoulder muscles to the Humerus (upper arm bone). When the tendon is torn due to injury, degeneration, or overuse, it can cause shoulder pain, weakness, and difficulty in arm movement.
The cuff consists of four muscles:
- Supraspinatus
- Infraspinatus
- Teres Minor
- Subscapularis
Types of Cuff Tears
- Partial Thickness Tear
- Full-Thickness Cuff Tear
- Acute Cuff Tear
- Degenerative Cuff Tear
1. Partial Thickness Tear
A Partial Cuff Tear occurs when the tendon is damaged but not completely severed.
Characteristics
- Tendon is frayed or partially torn
- Some tendon fibers remain attached to the bone
- Pain occurs during movement
- Shoulder strength is usually partially preserved
This type is common in early-stage injuries or degenerative changes.
2. Full Thickness Tear (Complete Tear)
A Full-Thickness Cuff Tear occurs when the tendon is completely torn from the bone.
Characteristics
- Tendon is fully separated from the humerus
- Significant weakness in shoulder movement
- Difficulty lifting the arm
- Often requires surgical repair
3. Acute Cuff Tear
An Acute Cuff Tear happens suddenly due to trauma or injury.
Common Causes
- Falling on an outstretched arm
- Lifting heavy weight suddenly
- Shoulder dislocation
- Sports injuries
Symptoms appear immediately after injury.
4. Degenerative Cuff Tear
A Degenerative Cuff Tear develops gradually over time due to wear and tear.
Common Causes
- Aging (most common after age 40–50)
- Repetitive overhead activities
- Poor blood supply to tendons
- Bone spurs in the shoulder
This type is more common in people with physically demanding jobs or athletes.
Common Symptoms
Patients with a cuff tear may experience:
- Persistent shoulder pain
- Pain while lifting the arm
- Weakness in the shoulder
- Difficulty reaching overhead
- Night pain, especially when lying on the affected shoulder
- Clicking or popping sensation in the shoulder
Risk Factors
Several factors increase the chances of developing a cuff tear:
- Age above 40
- Repetitive overhead activities
- Heavy lifting
- Sports like cricket, tennis, and swimming
- Occupations involving manual labor
- Poor shoulder posture
Diagnosis
Doctors diagnose a cuff tear using:
1. Physical Examination
The orthopedic specialist checks:
- Shoulder movement
- Muscle strength
- Pain location
2. Imaging Tests
Common imaging methods include:
- X-ray – Detects bone spurs or arthritis
- Magnetic Resonance Imaging (MRI) – Best test to detect tendon tears
- Ultrasound Imaging – Helps visualize tendon damage
Surgical Treatment
Surgery is recommended when:
- Tear is large or complete
- Symptoms persist for several months
- Shoulder strength is severely affected
Common Surgical Procedures
1. Arthroscopic Cuff Repair
Minimally invasive surgery using a small camera and instruments.
2. Open Cuff Repair
Traditional surgery for large tears.
3. Reverse Shoulder Replacement
Used in severe cases with massive cuff tears and arthritis.
Complications if Untreated
If a cuff tear is not treated early, it may lead to:
- Chronic shoulder pain
- Progressive tendon damage
- Shoulder weakness
- Limited arm mobility
- Development of Cuff Arthropathy
Summary
A cuff tear is a common shoulder injury affecting the tendons responsible for shoulder stability and movement. Early diagnosis and treatment—whether conservative or surgical—can help restore shoulder function and prevent long-term complications.
