Full- versus Partial-Thickness Achilles Tendon Tears: Sonographic Accuracy and Characterization in 26 Cases with Surgical Correlation

Abstract

Sonography can be used to differentiate full- from partial-thickness tears or tendinosis of the Achilles tendon with 92% accuracy. Undetectable tendon at the site of injury, tendon retraction, and posterior acoustic shadowing demonstrate statistically significant correlation with full-thickness tears.
