A torn tendon is diagnosed through a combination of medical history, physical exam, and imaging tests like X-rays (to check bones), ultrasound (to see soft tissues dynamically), and MRI scans (for detailed views of the tear's extent and location). Doctors look for pain, swelling, weakness, and gaps in the tendon, assessing range of motion and strength to pinpoint the injury and rule out other issues.

How do doctors check if a tendon is torn?

Ultrasound. This type of imaging test uses sound waves to make images of structures within your body, such as muscles and tendons. Magnetic resonance imaging (MRI). An MRI uses radio waves and a magnetic field to create detailed images of the affected area of the body.

What is the Thompson test on yourself?

The Thompson Squeeze Test is one. It checks if your foot moves down when your calf is squeezed. If it doesn't, it might mean a tear. Other tests, like the Calf Squeeze Test and the Single Leg Heel Raise Test, also check your tendon's strength and function.

What would a torn tendon feel like?

A torn tendon feels like a sudden, sharp pain, often with an audible pop or snap at the time of injury, followed by significant swelling, bruising, and profound weakness or inability to move the affected joint or limb. You might notice a visible gap or bulge (like a "Popeye" muscle) where the tendon has detached, and the area becomes tender, hot, and difficult to bear weight on or use.

Can a small tendon tear heal itself?

Usually, an injured tendon tends to get better on its own, but a full recovery can be difficult, regardless of age. A plastic surgeon may suggest physiotherapy. This would be for a more severe or long-lasting injury and a brace, splint, sling or crutch may be prescribed. These allow all tendons to rest and heal.

Best Way To Know If You Have A Torn Rotator Cuff

How do you know if you partially tore a tendon?

Occasionally, flexor tendons may be partially cut or torn. With a partial tendon injury, it may still be possible to bend your finger. However, partial tendon injuries may result in incomplete bending of the finger, excessive pain, or even catching or locking of the finger during movement.

What is the difference between a tendon tear and a ligament tear?

When these structures are damaged, it can result in pain, weakness, and limited range of motion. Ligament injuries often occur when the joint is forced beyond its normal range of motion, while tendon injuries are commonly caused by overuse, sudden movements, or trauma.

What is the Simmonds test?

The Simmonds–Thompson test, described in 1957 and 1962,1–3 respectively, remains the principal clinical test for rupture of an Achilles tendon. However, there is some discrepancy in the literature regarding its mechanical significance.

How long does a partial tear take to heal?

Recovery outlook: Partial tears typically heal within a few months to half a year with proper care. A complete tear may take up to a year or more to heal, depending on whether surgery is involved and the recovery plan.

What are the first signs of a torn Achilles?

Torn Achilles symptoms

• Pain around the Achilles tendon area (back of the heel)
• Swelling and thickening of the tendon.
• Instability and difficulty walking, especially on an incline or decline.
• Tenderness at the point of injury.
• Increased pain and stiffness with use.

What to do if you suspect a torn tendon?

You should see a doctor right away after tearing or rupturing a tendon or ligament. Swelling can affect the diagnosis of your injury. To diagnose a tendon or ligament injury or rupture, your doctor will get your medical history and do an exam.

What is the most common site of tendon rupture?

Achilles tendon rupture is the most common tendon rupture in the lower extremity. The injury most commonly occurs in adults in their third to fifth decade of life. Acute ruptures often present with sudden onset of pain associated with a "snapping" or audible "pop" heard at the injury site.

What are the early warning signs of a tendon rupture?

Warning signs of a tendon rupture include a sudden, severe pain and an audible pop or snap at the time of injury, followed by immediate bruising, swelling, significant weakness, and inability to move or bear weight on the affected limb, sometimes with a visible gap or deformity where the tendon has pulled away. These symptoms signal a serious injury requiring immediate medical attention. 

What does a minor tendon tear feel like?

Pain, tenderness, redness, warmth, and swelling near the injured tendon. Pain may get worse when you're active. Symptoms may affect just the spot where the injured tendon is located, or they may be spread out from the joint area. Crepitus, or a crunchy sound or feeling when the tendon is used.

Does a torn tendon hurt all the time?

The most obvious sign that something is amiss with your tendon is pain, which can range from occasional and mild to severe and constant, depending upon the extent of the damage.

How do you tell if a tendon is torn or strained?

You can tell a tendon is torn when the pain is sudden, sharp, and accompanied by common symptoms such as swelling or loss of movement in the joint. In contrast, a strain typically results from overstretched muscle fibers, causing mild tenderness or soreness rather than severe pain.

What promotes tendon healing?

Collagen Production: Nutrients like vitamin C, glycine, and proline are vital for collagen synthesis, which supports tendon strength and elasticity. Anti-Inflammatory Foods: Include omega-3 fatty acids (found in fish and nuts) to reduce inflammation and promote tendon repair.

Is heat or ice better for tendon pain?

After a sudden injury to a tendon, ice can ease pain and swelling. Ice the area for 15 to 20 minutes every 4 to 6 hours. And be sure to put a towel or cloth between the ice pack and your skin. Heat may be more helpful for ongoing tendon pain, often called tendinopathy or tendinosis.

What does tendon pain feel like?

Symptoms of tendonitis

pain in a tendon that gets worse when you move. difficulty moving the joint. feeling a grating or crackling sensation when you move the tendon. swelling, sometimes with heat or redness.

How can I test myself for tendonitis?

Procedure: With your thumb pointing upward, slowly raise your arm out to the side and overhead. Positive Sign: Pain occurring between 60° and 120° of elevation, which then decreases as you continue raising the arm, indicates a painful arc associated with shoulder impingement or tendinitis.

What is the squeeze test for arthritis?

In this test, the second through fourth metacarpophalangeal joints (see image, lower left) or the metatarsophalangeal joints (see image, lower right) are squeezed together to test for tenderness. A positive result raises the question of an inflammatory arthritis such as rheumatoid arthritis.

How to tell the difference between tendonitis and a torn tendon?

One way that helps us to diagnose a tear is to determine if there was trauma to cause the injury. If someone fell or was hit and the person suffered an injury, then we'd suspect it was a tear and not tendonitis. Tendonitis is usually due to repetitive movements and not due to trauma.
