The ultrasonographic characterization of tendons

Ultrasonography has not been utilized in the diagnosis of musculoskeletal disorders. However, the superficial location of tendons and ligaments lend themselves to evaluation by this modality. The ultrasonographic characteristics of the normal Achilles tendon are described in both the rabbit and man. The characteristic ultrasonographic findings after injury to the Achilles tendon are also determined. This imaging technique provides a sharp definition of the tendon and surrounding structures and easily demonstrates abnormalities. The superficially located quadriceps tendon is also well visualized by ultrasound and representative examples are shown. Ultrasound should be considered as another useful method for evaluation of these superficial musculoskeletal structures.
