Recent research has indicated that while the test is an accurate detector of achilles rupture, it is unable to distinguish between partial tear (tear of the gastrocnemius or soleal portion only) and a complete tear of both portions.

The Achilles tendon is short or absent in great apes, but long in arboreal gibbons and humans. [38] It provides elastic energy storage in hopping, [39] walking, and running. [38] Computer models suggest this energy storage Achilles tendon increases top running speed by >80% and reduces running costs by more than 75%. [38]
Achilles tendon rupture seen on ultrasound. Note discontinuity over several centimeters (red line). No fracture or avulsion (radiograph). Ultrasonography can be used to determine the tendon thickness, character, and presence of a tear. It works by sending harmless high frequencies of sound waves through the body.
Tendinopathy is a type of tendon disorder that results in pain, swelling, and impaired function. [2] The pain is typically worse with movement. [2] It most commonly occurs around the shoulder (rotator cuff tendinitis, biceps tendinitis), elbow (tennis elbow, golfer's elbow), wrist, hip, knee (jumper's knee, popliteus tendinopathy), or ankle (Achilles tendinitis).
Achilles tendon tightness is a risk factor for plantar fasciitis. It can lead to decreased dorsiflexion of the foot. Heel bone with heel spur (red arrow) Thickened plantar fascia in ultrasound. Plantar fasciitis is usually diagnosed by a health care provider after consideration of a person's presenting history, risk factors, and clinical ...
The Achilles tendon is wider than normal, further suggesting inflammation. Achilles tendinitis is usually diagnosed from a medical history , and physical examination of the tendon. Projectional radiography shows calcification deposits within the tendon at its calcaneal insertion in approximately 60 percent of cases. [ 17 ]
It is also known as retrocalcaneal exostosis, Mulholland deformity, and ‘pump bump.' It is a very common clinical condition, but still poorly understood. Haglund's deformity is an abnormality of the bone and soft tissues in the foot. An enlargement of the bony section of the heel (where the Achilles tendon is inserted) triggers this condition.
Acoustoelastography is an ultrasound technique that relates ultrasonic wave amplitude changes to a tendon's mechanical properties. [ 1 ] See also the page on the acoustoelastic effect .
