What special tests are done for Achilles rupture?

A Thompson test is performed to determine if the Achilles tendon is ruptured. This is done by squeezing the calf muscles while the patient is kneeling or lying face down with feet hanging unsupported.

What is positive Thompson test?

A positive test has been reported to indicate a complete rupture of the tendon,4 and the cited mechanical reason for the positive test (complete rupture) is the loss of integrity of the soleal part of the tendon.

What is the Achilles pinch test?

The Achilles tendon pinch test is performed by pinching the medial and lateral sides of the Achilles tendon, superior to the location of the bursae. The presence of pain usually confirms tendinitis. Swelling will be palpably and visibly present.

What is a negative Thompson test?

When squeezing the right (unaffected) calf, the ankle spontaneously plantar flexed, indicating a negative (normal) Thompson test. Upon squeeze of the left (affected) calf, the ankle did not plantar flex, signifying a positive (abnormal) Thompson test.

Which assessment finding would be apparent in a patient with a ruptured Achilles tendon?

Physical examination findings include increased passive ankle dorsiflexion, weak plantar flexion strength, and a palpable defect overlying the tear.

What is Thompson test for Achilles?

Thompson Test – Physiopedia Definition/Description The Thompson test examines the integrity of the Achilles tendon by squeezing the calf. It is performed as a clinical test to identify the presence of a complete Achilles rupture.

How reliable is the Thompson test?

The sensitivity of the Thompson’s test for the diagnosis of a complete Achilles tendon rupture is 96-100% and the specificity is 93-100%, but data is limited.

Is Thompson test accurate?

The Thompson test is an accurate clinical test for diagnosing complete Achilles tendon ruptures. However, it might not be a useful test for diagnosing partial Achilles tendon ruptures.

What test shows a torn tendon?

MRI (magnetic resonance imaging), which can show small tears and areas of tendon, ligament, cartilage, and muscle injury. Ultrasound, which can show thickening, swelling, or tears in soft tissues such as the bursae and tendons.

What injury does a patient have if the Thompson test is positive?

The Thompson test examines the integrity of the Achilles tendon by squeezing the calf. It is performed as a clinical test to identify the presence of a complete Achilles rupture.

Do you need an MRI to diagnose a torn Achilles tendon?

MRI is unnecessary for diagnosing acute Achilles tendon ruptures: clinical diagnostic criteria.
