Ultrasound
Complete avulsion of the Achilles tendon from its insertion. Retraction is 45 mm with dorsal foot flexion and 33 mm with plantar foot extension. Mild changes of tendinosis in the retracted tendon along with enthesophytes represented by small bone flakes. The plantaris tendon is intact. Dynamic scan (during foot flexion-extension movements) does not show the movement of the proximal tendon.
The asymptomatic side Achilles tendon is intact along with enthesophyte.
